-# Gitea Actions CI gate for the self-hosted runners.
-#
-# Deliberately does NOT use actions/setup-dotnet: data.forgejo.org (the mirror
-# Gitea resolves actions from) does not host that action at all, and the
-# self-hosted runners carry the pinned SDK band from global.json already.
-# actions/checkout IS mirrored, so it is used normally.
-#
-# The suite runs through tools/run-release-gate.ps1 rather than a bare
-# `dotnet test`: that script owns the xUnit trait-lane filter which excludes
-# the InstalledDat / Live / Manual / OS-specific lanes. A bare `dotnet test`
-# fails ~36 tests by design because those lanes assert their own preconditions.

-Allegiance is the authored DEFAULT tab), mounted with the OP3 Options-panel
-recipe. The Fellowship and Allegiance pages are LIVE end-to-end: real wire

-the truncated XP-share table), two session-scoped Runtime owners
-(`RuntimeFellowshipState`/`RuntimeAllegianceState`, both clear at
-generation reset — D2 corrected), and the authored panels through
-`LayoutImporter`. Friends/Squelch bind read-only to J4.1's owners.
-**The fellowship two-session flow is PROVEN over the live wire** — FA6's
-automated bot-vs-ACE gate (`testaccount`/`+Acdream` + `testaccount2`/
-`+Horan`) passed: the recruited bot's OWN `RuntimeFellowshipState` flips

-already binding: retail's select screen (`gmCharacterManagementUI`) has
-NO 3D preview (chargen-only machinery); UI Studio no longer exists
-(deleted at Campaign V — ignore stale memory/docs claims otherwise);
-App `Program.cs` has no subcommand dispatch (the `--session-config` flag
-is additive).
-LA0 through LA11's automated scope are review-closed. The launcher composer is now
-compiled into both host test suites, and Launcher.Core runs in the portable
-Windows/Ubuntu CI closure. The self-contained Avalonia launcher,
-transactional two-host plugin lifetime, shared login-command route,
-Runtime-owned retail selection state, authored DAT character screen, and

-are integrated. Windows group-isolated Headless stop, isolated update fixtures,

-one extended round (findings GF-1..16 + re-tests R2/R3/R4, fix batches
-A-G + closeout + two re-test rounds, final build `1.0.2-cc.o`) and
-PASSED. **Milestone: the first live character ever created by acdream
-against ACE landed mid-round.** The gate round's own harvest hardened

-the authored Unselected/Selected state pair + per-state label color,
-un-consumed Type-12 media children (frames/scrollbars client-wide),
-single-sprite scrollbar thumbs, UiButton/UiDatElement Tint, the
-dialog-always-on-top re-raise (the invisible-modal input blackhole), a
-truthful client crash self-report + bounded stderr capture (#405-#407
-fixed, #406 fixed; #408/#409/#410 filed for their own rounds). The full retail creation flow: Create
-button (retail's exact `UpdateButtons` roster<slots ghost gate) →
-`gmCharGenMainUI`'s six-page flow (Heritage / Profession / Skills /
-Appearance with live 3D preview / Town / Summary with its own zoomed-out

-0xF643 handling (roster append + retail log-straight-in; every rejection
-dialog, incl. the corrected ground truth that retail shows NameDBDown
-for Pending/Undef — the plan's original "retail swallows it" was
-DISPROVEN at CC5's review) → the §LA1 `characterCreated`/`creationFailed`
-launcher status cycle. `RandomizeCharacter` + sub-primitives are ported

-cost the most that campaign: a contract asserting a mechanism that does not
-exist caused three separate defects, and inferring a fact you can observe
-made one fix strictly worse than the bug it replaced — it removed the
-invariant failure while leaving the bug.

-# acdream application icons
-
-Two marks, one family.
-
-| Mark | Files | Used by |
-|---|---|---|
-| **Client** — the mosswart head | `acdream-client-*.png`, `acdream-client.ico` | `AcDream.App` (PE icon + runtime window icon) |
-| **Launcher** — the ring and crescent | `acdream-launcher-*.png`, `acdream-launcher.ico` | `AcDream.Launcher` (PE icon + Avalonia `Window.Icon`) |
-
-Each ships PNGs at 16/24/32/48/64/128/256/512/1024 plus a multi-size `.ico`
-carrying 16 through 256.
-
-## Where the art comes from
-
-**The client mark is the retail mosswart**, not a drawing of one. It is the
-actual creature head — `Setup 0x02000B4F` part 14, skin atlas `0x05001E11`,
-`ClothingBase 0x10000344` — pulled from `client_portal.dat`, smoothed, lit and
-graded. Palette values throughout both marks are sampled from that texture:
-
-| | |
-|---|---|
-| `#ACB820` | chartreuse upper skin |
-| `#A09800` | mustard belly — the "foul yellow" the lore names |
-| `#485010` | deep olive shadow |
-| `#F2ECD2` | tusk bone |
-| `#AC7438` | ear membrane / hide |
-
-**The launcher mark is inspired by the Asheron's Call sigil** — a forged ring
-enclosing a hooked crescent — rebuilt from measurements of the retail wordmark
-and the `acclient.exe` icon resource. It is an original construction in the
-same visual language, not a copy of the logo. Its warm field matches the retail
-client icon's dark-to-gold interior.
-
-> **Note on rights.** "Asheron's Call" and its logo are trademarks of their
-> owners, and the client mark is rendered from copyrighted game art. Unlike DAT
-> content — which stays on the user's own disk — these icons are compiled into
-> the shipped binaries. If acdream is ever distributed broadly, both marks
-> should be reviewed, and the client mark is the one most likely to want an
-> original redraw using these renders as reference.
-
-## Regenerating
-
-The launcher mark is fully procedural and rebuilds anywhere:
-
-```bash
-py tools/IconForge/forge.py launcher
-```
-
-That is byte-for-byte deterministic — it reproduces the committed PNGs exactly,
-so an accidental edit is visible as a diff.
-
-The client mark renders real game geometry, so it needs the installed DATs.
-One command extracts both halves — the posed geometry and the surfaces it
-references — into `tools/IconForge/work/`:
-
-```bash
-dotnet run --project tools/MosswartArt -- 0x02000B4F 0x10000344 tools/IconForge/work/mosswart_mesh.json 0x09000009
-```
-
-The trailing MotionTable id is required. Creatures do not define an upright pose
-in `Setup.PlacementFrames`; without it every part stacks on the origin.
-
-Then:
-
-```bash
-py tools/IconForge/forge.py client
-```
-
-This is deterministic too — given the same DATs it reproduces the committed
-PNGs byte-for-byte.
-
-Requires Python with `numpy`, `pillow` and `scipy`.
-
-## How they are wired in
-
-Neither icon is loaded from disk at runtime.
-
- **PE icon** — `<ApplicationIcon>` in each `.csproj`, pointing at the `.ico`
-  here. This is what Explorer and the taskbar shortcut show.
- **Client window icon** — `AcDream.App.Rendering.WindowIconLoader` hands GLFW
-  four sizes **from the `Load` callback**. That timing is load-bearing: Silk's
-  `Window.Create` only builds the managed object, and `IWindow.Initialize` is
-  what creates the native window, so applying an icon any earlier throws
-  "Window should be initialized". The failure is quiet and misleading — GLFW
-  falls back to the stock Windows application icon rather than the
-  executable's, so Explorer shows the mark and the running window does not.
-  The PNGs are *embedded resources* linked from this directory, so there is one
-  source of truth for the art and no missing-file case at runtime.
-  `WindowIconLoaderTests` guards both the resource names, which are otherwise
-  coupled to `LogicalName` in the csproj by string only, and the call-site
-  ordering.
- **Launcher window icon** — `AvaloniaResource` linked from here, referenced as
-  `avares://acdream-launcher/Assets/acdream-launcher.png`.

-# Continuous integration and alpha releases (Gitea)
-
-Single source of truth for how acdream builds, gates, and ships alpha builds.
-Landed 2026-08-19. Companion to [`release-gate.md`](release-gate.md), which
-owns the *local* bounded gate.
-
-## What happens on a push to main
-
-```
-git push origin main
-        │
-        ├─ windows-gate    (RARE-win)        build + full lane-filtered suite
-        ├─ linux-portable  (eriktestLinux)   portable closure, Linux lanes
-        │
-        └─ release   (needs BOTH green)      publish a Gitea Release
-                                             + republish the `latest` pointer
-```
-
-Workflow: [`.gitea/workflows/ci.yml`](../.gitea/workflows/ci.yml). Docs-only
-pushes (docs/, the memory trees, markdown) skip the pipeline entirely — no
-test can fail on them and a run costs ~7 minutes plus a 121 MB release. A red gate
-cannot publish: `release` uses `needs:`, not a `workflow_run` trigger, whose
-Forgejo support is unreliable.
-
-## Why Gitea and not GitHub
-
-GitHub Actions is **billing-blocked** on this account ("recent account payments
-have failed"), and the repo is private, so hosted runners consume paid minutes.
-Forgejo ships **no hosted runners at all**, so Actions there requires
-self-hosted ones — which are free on both platforms. The same two machines can
-serve GitHub later by registering a second agent; only the workflow's
-`runs-on` labels change.
-
-## The runners
-
-| | Windows | Linux |
-|---|---|---|
-| Host | `RARE` (10.6.0.3) | `eriktestLinux` (10.0.0.202) |
-| Agent | `act_runner` 0.2.13 | `forgejo-runner` 13.0.0 |
-| Persistence | Scheduled task `ForgejoRunner`, at logon of `acbot` | systemd `forgejo-runner`, `Restart=always` |
-| Labels | `windows`, `windows-latest`, `windows-x64` | `ubuntu-latest`, `ubuntu`, `linux`, `ubuntu-slim` |
-| Execution | host mode (`:host`) — no Docker on either box | host mode |
-
-Both **poll outbound** over HTTPS. Gitea never connects to them, so no inbound
-ports, no port forwarding, and no static IP; they work behind NAT. The runner
-does not have to live next to the Gitea container (which runs on `bluesnake`,
-a host we have no shell on).
-
-`forgejo-runner` publishes **no Windows binary in any release**, which is why
-Windows uses Gitea's `act_runner`. Forgejo speaks the same Actions protocol.
-
-### Prerequisites on a runner
-
- **.NET SDK in the `global.json` band** — currently `10.0.3xx`. `10.0.400` is a
-  different feature band and `rollForward: latestPatch` rejects it.
- **Node.js** — `actions/checkout` and `actions/upload-artifact` are JavaScript
-  actions. Docker images normally supply Node; in host mode the machine must.
- **Git**, and outbound HTTPS to `git.snakedesert.se`.
- **PowerShell 7** on Windows (`pwsh`); `tools/*.ps1` require it.
-
-## Releases
-
-Everything about distribution lives under **Releases** — nothing in git. A build
-is ~120 MB, so payloads are release attachments; and the pointer the launcher
-polls is itself a release asset, so there is no payload branch, no bot commit on
-`main`, and no push that could retrigger the pipeline.
-
-```
-Release  0.1.0-build.<yyyyMMddHHmm>     <- the actual build
-  client-win-x64.zip      AcDream.App.exe + acdream-headless.exe
-  launcher-win-x64.zip    acdream-launcher.exe + acdream-bake.exe
-  manifest.json
-
-Release  latest                          <- pointer, replaced every publish
-  manifest.json           names the version above and its asset URLs
-```
-
-The launcher polls the pointer at a URL that never changes
-(`ReleaseManifestClient.ProductionManifestUri`):
-
-```
-https://git.snakedesert.se/erik/acdream/releases/download/latest/manifest.json
-```
-
-A pointer is needed because **Forgejo has no `/releases/latest/download/`
-route** (verified: 404) — unlike GitHub, there is no built-in stable URL for
-"the newest release". Publishing it recreates the `latest` tag each time, which
-means deleting the old release *and* its tag; the tag outlives its release and
-would otherwise block recreation.
-
-The newest **5** versioned releases are kept and older ones are pruned with
-their tags. Each build is ~121 MB of attachments, so retaining every one grew
-the server by that much per push — 5 builds had already reached 606 MB. Five is
-enough to grab a previous build or bisect a regression while staying bounded.
-The `latest` pointer is never pruned; it is the feed, not a build.
-
-`tools/publish-bin.ps1 -BaseUrl <release asset base>` builds the payloads; CI
-passes the tag's asset base. Running it locally is for inspection only —
-publishing is CI's job.
-
-### Verifying a release
-
-```powershell
-dotnet test tests/AcDream.Launcher.Core.Tests --filter Lane=Live
-```
-
-`LiveGiteaReleaseInstallTests` installs the advertised client from the real feed
-through the production updater — real SHA-256/size verification, extraction, and
-atomic activation — then asserts both hosts resolve out of the activated
-directory and `current.json` names the installed version.
-
-## Landmines
-
-Each of these cost a red pipeline; none was a config typo. Two rows record a
-fix that was tried and **disproved** — read those before repeating it.
-
-| Symptom | Cause |
-|---|---|
-| `Cannot find: node in PATH` | JS actions need Node on the host in `:host` mode |
-| `actions/setup-dotnet` never resolves | `data.forgejo.org` does not mirror it (404). `checkout` and `upload-artifact` **are** mirrored. Self-hosted runners carry the SDK anyway |
-| Job "failed" while dotnet processes still run | `run-release-gate.ps1` redirects children to log files, so the step goes silent; Forgejo fails a non-reporting task as a zombie. CI runs `dotnet test` directly so output streams |
-| ~40 tests fail on formatted numbers | Runner's `HKCU` locale was `en-SE` (comma decimal): expected `"update:0.25"`, got `"update:0,25"`. `Set-Culture` does **not** reach a scheduled task without a loaded profile — set the registry directly |
-| `DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1` as the locale fix | Too blunt — it breaks tests that legitimately construct a culture. Fix the machine locale instead |
-| `FileNotFoundException: client_cell_1.dat` | DAT-dependent tests missing `[Trait("Lane", "InstalledDat")]`. Build machines have no DATs |
-| Timing-sensitive test fails only under load | It belongs in `Lane=Timing` (see [`release-gate.md`](release-gate.md)). Do **not** chase these individually: four separate fixes each surfaced a different member of the same family, and serializing `Core.Net` to fix Linux regressed Windows from 1000 passed in 7 s to 999/1000 in 17 s |
-| Avalonia "calling thread cannot access this object" in cleanup | `MainWindowViewTests` needs a real desktop session and is `Lane=Manual`. Measured: PASSES on a dev desktop and on the CI Windows box over SSH; FAILS under `act_runner` and on Linux. Serializing the assembly does **not** fix it (tried via `xunit.runner.json` and a compiled-in `CollectionBehavior` attribute), and de-async-ing the test actively causes the failure. The stack shows a compositor being **constructed** during teardown — it is the headless session lifecycle, not parallelism |
-
-## Do not leave load on a runner
-
-A stress/diagnostic run left going on a runner competes with CI for the same
-machine and makes every job slower and more likely to trip a load-sensitive
-test — the exact failures you would then be trying to diagnose. Kill background
-work before trusting a timing result:
-
-```powershell
-Get-Process dotnet -ErrorAction SilentlyContinue | Stop-Process -Force   # Windows
-pkill -9 dotnet                                                          # Linux
-```
-
-Leave `act_runner` / `forgejo-runner` itself alone; killing those unregisters
-nothing but stops the machine picking up jobs until it restarts.
-
-## Culture note
-
-The `en-SE` discovery is worth remembering beyond CI: config files, numeric
-parsing, and the wire are all culture-safe (`System.Text.Json` is invariant by
-spec, every `float/double.TryParse` passes `CultureInfo.InvariantCulture`, and
-the protocol is binary). Only **diagnostic strings** format with the current
-culture, so a European player sees `local=(8,00; 191,00)` in an F3 dump. The
-client installs and runs correctly in both the US and Europe.

-2026-07-31. The final session also accepted burden/exhaustion, wall/corner,
-crowd, two-client remote/door/portal, and shallow-water behavior. The user

-**Campaign A — audio retail parity (CODE-COMPLETE 2026-08-08):** ported
-retail's CPU-side 2-D pan+gain audio model (animation-hook sounds, the
-`0xF750` server sound channel, PhysicsScripts, the interface sound bank,
-and the region ambient system); found and corrected three false claims in
-the old E.2 row (no 3-D pool, gain-based eviction, weighted variant
-picking) and deleted the music API (retail has none). Slices A1–A6 landed;
-open tail is #358 (Ctrl+M mute chord never fires) and the formal
-plan-status flip. Plan:
-[`2026-08-08-audio-parity-campaign.md`](2026-08-08-audio-parity-campaign.md).
-
-**Campaign CH — chat & interface-text retail parity (CODE-COMPLETE
-2026-08-09, pending the connected user gate):** four implementation
-slices closing the chat surface's biggest retail-parity gaps ahead of the
-friend-alpha: CH1 the complete 34-value `LogTextType` color table, CH2
-the on-screen SpewBox interface text (jump-refusal class, WeenieError
-routing table), CH3 side-channel membership/wire/echo parity (Turbine
-rooms, the legacy family, self-echo), and CH4 command registry completion
-(138 of 152 retail verbs now execute locally). Every slice landed a
-dual-Opus review (retail faithfulness + architecture) before its gate;
-full Release suite 12,221 passed / 4 skipped / 0 failed. Plan and ledger:
-[`2026-08-09-chat-parity-campaign.md`](2026-08-09-chat-parity-campaign.md);
-in-client acceptance script:
-[`2026-08-09-campaign-ch-test-script.md`](../research/2026-08-09-campaign-ch-test-script.md).
-
-**Campaign LA — launcher/installer/updater + retail character-select
-(ACTIVE 2026-08-14):** the alpha-program launcher: an Avalonia app
-(Windows + Linux) doing triple duty — install (DAT locate → `acdream-bake`
-with progress → SHA record), update (GitHub Releases manifest, verified
-download, atomic version swap, launcher self-update), and launch
-(ThwargLauncher-model server × account × character profiles with full
-in-UI CRUD; plaintext credential file by explicit user decision).
-File-contract orchestration of both hosts: session config in (K1 shape +
-plugins + login commands), password via child stdin, versioned JSONL
-status events out. Adds the headless character-list probe, plugin hosting
-+ login commands on both hosts, and the retail character-management
-screen (recon-corrected: `gmCharacterManagementUI` is a flat listbox with
-Enter/Delete/Restore — NO 3D preview on retail's select screen; Create is
-a future campaign). Spec:
-[`2026-08-14-launcher-campaign-design.md`](../superpowers/specs/2026-08-14-launcher-campaign-design.md);
-plan + ledger:
-[`2026-08-14-launcher-campaign.md`](2026-08-14-launcher-campaign.md).
-LA0 through LA11's automated scope are review-closed: the portable path boundary,
-failure-isolated launch/status contract, BCL-only launcher core, shared
-composer-to-both-host-loader anti-drift gate, and character wire messages are
-landed. The self-contained Avalonia launcher, transactional two-host plugin
-lifetime, shared login-command route, Runtime-owned retail selection state,
-authored DAT character screen, crash-safe verified installer, and atomic
-cross-platform updater/self-updater are integrated. Windows group-isolated
-Headless stop, isolated A/B update fixtures, strict status/redaction evidence,
-and one exact Windows/Ubuntu operator script are also landed. The integrated
-clean preflight passes 32/32 commands and 14,012 tests / 5 skips. Campaign code
-is complete but not shipped: the connected/visual/real-DAT user gate is the
-only remaining boundary.
-
-**Remaining physics-divergence closeout (ACTIVE, checkpoint 2026-08-03):** the user then
-authorized retirement of the remaining proven collision/placement gaps before
-vendor work resumes. Nested retry, edge/StepDown/Path-6 ordering, exact cell
-availability, atomic collision generations, canonical Core SetPosition,
-Runtime lost-cell residence, authored mover/body preparation, placement
-receipts and observers, collision-prefix replacement, authoritative route
-classification, and initial Create residence are landed as bisectable
-checkpoints. Commit `38fd4b8d` retains the accepted Create placement plus
-fresher Position FIFO until exact placement and ordered adoption complete.
-Commit `30012361` completes the bounded inbound-admission checkpoint: all
-accepted mixed updates remain deep-frozen in exact arrival order while the
-initial placement waits, with no early canonical/public snapshot, event, or
-presentation mutation. Missing-parent raw Create, delete, reconnect/reset,
-GUID reuse, malformed projections, saturation, and reentrant teardown are
-covered. Commit `5db3de3c` (2026-08-02) completes the continuation executor:
-retry-idempotent single adoption of the acknowledged initial placement,
-retail's exact Create tail, GUID-keyed deferred-child and parent-relation
-replay with cancellation-aware windows, strict-sequence mixed-FIFO drain with
-execution-time retail Position routing, shared apply bodies keeping one
-snapshot store in lockstep, and converged ownership ledgers on every
-abandonment path — dual independent reviews PASS; register rows
-AD-59/AD-60/AP-130/AP-131/AP-132/TS-62/TS-63 filed in the same commit.
-Production initial Create registration is now cut over by C3c (`529e0e9d`).
-The O(changed) collision-publication checkpoint and five stabilization fixes
-through `175ad6b0` restore recenter convergence, remote world-frame placement
-and targeting, distant Use, one-shot spell/projectile/static effects, and
-login materialization; the corresponding connected user gates passed. The
-fixture reconciliation closed 2026-08-03 as #281 (the recorded "six" measured

-3. `ShopSystem::BuyPrice`/`SellPrice` (0x006B6120/0x006B6180,
-   byte-identical to ACE's `GetBuyCost`/`GetSellCost`) are ported NOW as
-   pure Core functions with golden-value conformance tests — the browse
-   list shows retail-correct prices from day one.
-4. No request-correlation token in Slice 5: the panel always opens on the
-   browse/Buy tab. Slice 6 adds the sell-initiated correlation.
-5. `VendorProfile::InqAcceptability` (which player items the vendor would
-   accept) is deferred to Slice 6 with the sell UI it gates.
-6. Category/type filter tabs are IN SCOPE for retail parity. The
-   implementer's D0 reads `VendorItemsUI::AddTypeFilter` /
-   `ListContainsType` (around 0x004C05C0/0x004C0D90) into a pseudocode
-   note before any UI work; if that read reveals a mechanism too large
-   for this slice, STOP and report (fallback — flat list + register row —
-   requires explicit approval, not implementer discretion).
-7. The vendor panel's top-level LayoutDesc id is NOT yet known: the UI
-   piece budgets a LayoutImporter discovery pass (the exact process that
-   found the examination window's 0x2100006B), cross-checked by the two
-   known tab-control ids (0x100000B9 Buy / 0x100000BB Sell) resolving
-   under the candidate root.
-8. AP-110 is narrowed in the SAME COMMIT that lands the panel: "vendor"
-   leaves the absent-panels list; whatever sub-scope remains absent after
-   this slice gets its own precise row.
-
-### Ordered work (each lands separately, bisectable)
-
- **5.0** — extract the shared `PublicWeenieDesc`-body parser
-  (behavior-preserving; wire tests unchanged; no vendor code).
- **5.1** — `ApproachVendor` (GameEvent 0x0062) inbound parser:
-  `VendorProfile` + the full-desc item list, against the research doc's
-  byte-verified field table; Core.Net tests with golden byte fixtures.
- **5.2** — `VendorState` in Core.Items + the BuyPrice/SellPrice pure
-  port + conformance tests.
- **5.3** — Runtime ownership: `RuntimeInventoryState` owns the vendor
-  session per the J4.2 pattern (generation-gated, torn down on
-  reset/portal/logout); the 0x0062 route opens it; close is CLIENT-LOCAL
-  (nothing sent on the wire) via the retail distance-watcher semantics;
-  `ItemInteractionController._activeVendorId` /
-  `ItemInteractionPolicy.ActiveVendorId` finally receive the real id.
- **5.4** — the authored vendor panel: layout-id discovery, LayoutDesc
-  import via the Slice-3 examination-window pattern (foreground stacking,
-  authored extent), browse list reusing Slice-1's retained list/scrollbar
-  + DAT icon resolution, category tabs per the D0 read, prices via 5.2.
- **5.5** — register narrowing (decision 8) rides the 5.4 landing commit.
-
-### Trap list (binding)
-
-Do not touch: the J5.2 strict use gate's semantics (the vendor open rides
-the EXISTING use transaction — no second gate, per the J4.5 invariant);
-`CreateObject.TryParse` behavior (5.0 is extraction only); anything in the
-Slice 6 fence (no buy/sell wire, no currency mutation, no
-InqAcceptability). New event handling follows the newest existing
-GameEvent handler's registration pattern, not a bespoke route.
-
-### Gates
-
-Per landing: build + full suite green (clean-room before each landing
-commit). Slice gate (user, connected, ~3 min): approach a Holtburg
-vendor, use them, the authored panel opens on the browse tab with
-retail-correct items/icons/prices; category tabs filter; walking out of
-range closes the panel by itself; nothing is purchasable anywhere.
-
-## Slice 6 — vendor transactions, buy arc (contract authored 2026-08-08; user-pulled forward)
-
-**Research:** `docs/research/2026-08-08-slice6-vendor-transactions-research.md`.
-User direction: "I cant buy anything... Fix that first." Root cause of all
-four reported symptoms: `VendorUiController` never touches the shared
-`SelectionState`/`StackSplitQuantityState` owners every other panel uses.
-
-### Decisions
-
-1. **Shop items materialize into `ClientObjectTable`** while the session is
-   open (retail creates real CWeenieObjects from the vendor list — Slice 5
-   research §A.2) and are REMOVED on session close/replace/reset. The
-   implementer verifies retail's removal site (gmVendorUI::CloseVendor
-   family) and mirrors its lifecycle. This dissolves F7c's blocker:
-   `ExamineItemRequested` gets wired in this slice.
-2. **Vendor selection is the GLOBAL selection**: a new vendor change source
-   on the canonical `SelectionState`; row-click selects through it; the
-   status bar and the existing byte-faithful `StackSplitQuantityState`
-   slider follow automatically (the split-size mask helper from 5.4's F2
-   feeds the vendor-owned seeding exactly as gmToolbarUI does at
-   pc:198635-198790).
-3. **Buy = retail's Buy button**: immediate single-item purchase
-   (gmVendorUI::BuySingleItem, pc:201661) of the selected item with the
-   slider-chosen quantity for stacks. Outbound `0x005F`: vendorGuid,
-   count, per-item (i32 amount, u32 guid), TRAILING u32
-   alternateCurrencyId — the real client sends it (CM_Vendor::Event_Buy,
-   pc:689288) even though ACE's reader ignores it; we port the real
-   client. The request rides the EXISTING J5.2 one-request-at-a-time
-   reservation and completes on `UseDone` (0x01C7) — already the wired
-   completion signal; no second gate.
-4. **Reconciliation is the existing inbound machinery**: money property
-   updates, inventory CreateObject, and the ApproachVendor refresh
-   (VendorState.Refreshed) all flow through landed handlers — the slice
-   VERIFIES the loop end-to-end rather than adding an owner.
-5. **No double-click-to-buy**: retail has no such mechanism (confirmed
-   against the full named table). We match retail. If the user wants it
-   as a deliberate modernization it needs their explicit call + an AP row.
-6. **Deferred, still AP-161**: the Add button / Buying-tab staging list
-   and everything Sell (0x0060 — researched, next arc).
-
-### Ordered work (one implementer, bisectable commits)
-
- **6.1** shop-item materialization + removal lifecycle + examine wiring.
- **6.2** the selection coupling (source, row-click, split seeding) —
-  status bar + slider light up.
- **6.3** the 0x005F builder (golden-byte tests incl. the trailing dword),
-  Buy-button wiring, gate/UseDone completion, and the verified
-  reconciliation round-trip. Register: AP-161 narrowed in the landing.
-
-### Gate (user, connected)
-
-Select a stacked item → it shows in the status bar with the slider; pick
-a quantity; Buy → coins drop by the displayed price, the stack lands in
-the pack, the shop refreshes; a single-item buy works; insufficient funds
-fails cleanly; the session still closes on walk-away/portal with the
-materialized items removed.
-
-## Slice 6b/6c — vendor completion (contract authored 2026-08-08)
-
-**Research:** `docs/research/2026-08-08-slice6b-vendor-completion-research.md`.
-Closes the user's seven-finding gate batch (dropdown polish landed at
-`33b45ee5`). Ordered chunks, one implementer:
-
-1. **Move-to-use (Q2):** wire the existing client-predicted approach
-   primitive (`PlayerInteractionMovementSink.BeginApproach`,
-   `MovementType.MoveToObject` — today Pickup-only) onto `RequestUse`, so
-   using a vendor (or anything) beyond range walks the player in first,
-   retail's shape. No new movement machinery.
-2. **Buy staging (Q3):** `AddToBuyList` semantics per the research
-   trace — Add stages the selection + slider quantity into the Buying
-   tab's list (rendered count/price), Buy on that tab sends ONE batched
-   0x005F with every staged entry, the two removal shapes + Clear, and
-   retail's X-close confirm dialog when staging is non-empty (the current
-   unconditional hide stays correct only for empty staging).
-3. **Selling (Q4):** the Selling tab's list is THE drop target — accept
-   pack-item drops via the `ExternalContainerController` drag-handler
-   pattern, filter through `InqAcceptability` (all four rejection reasons
-   with retail's exact strings), staged sell list, batched 0x0060, and
-   the existing reconciliation machinery.
-4. **Status bar (Q5) — user evidence is the axiom:** the code-reading
-   says our chain already matches retail, but the user's live session
-   says the stack count/value/split-bar presentation is absent for a
-   vendor selection. Reproduce in a UI-level test FIRST (drive the real
-   SelectedObjectController mount with a vendor selection); fix what the
-   reproduction reveals; if it genuinely cannot reproduce, STOP and
-   report with the test as evidence for a live-probe session.
-5. **Pack order (Q1):** code-verified correct (wire placement position →
-   front insert). NO change; the gate re-checks it live and #352 gets
-   filed only if it reproduces.
-
-Register: same-commit rows for any deviation; AP-161 narrows again as
-staging/sell land (its remaining scope should shrink to nothing or to
-precisely what stays absent).
-
-**Gate (user):** click a vendor from afar → walk-in + open; stage two
-different items with quantities → Buy All → one transaction, coins/items
-correct; drag a sellable item onto the Selling tab → stages → Sell →
-coins up, item gone; an InqAcceptability-rejected item shows retail's
-refusal; X with a staged list → confirm dialog; stacked selection shows
-count/value/split-bar in the toolbar; bought items land at the front of
-the pack.
-
-## PROGRAM CLOSEOUT — 2026-08-08: all six slices COMPLETE, user-accepted
-
-Slices 5 and 6 closed together after the vendor arc's final gates. The
-complete retail vendor experience is live and user-verified end to end:
-walk-to-use from afar (the never-animated-target physics-host resolver +
-the cylinder-gap range watcher), the authored panel with the scrollable
-category dropdown (arrow-cap, downward, left-aligned), retail cost
-sentences with live purse repaint on every money change, per-unit and
-whole-stack pricing per the split-size mask, the MaxStackSize quantity
-slider with the right-justified count entry and two-line name wrap in
-the toolbar, staged buying (accumulate + 5000 cap + shop-row decrement +
-the four pre-send guards + the batched 0x005F + the X-close confirm),
-selling (Selling-tab drop target with drag-over auto-switch,
-InqAcceptability with verbatim rejection strings, BF_RETAINED, batched
-0x0060), double-click-to-buy (AP-171, user-approved modernization),
-prepend pack ordering (the cross-queue placement replay), and
-materialized shop objects with ownership-checked lifecycle + examine.
-
-Four adversarial Opus reviews found 34 defects before the user saw them;
-the user's connected gates found eleven more that only live sessions
-expose; two latent client-wide crashers (#348 cursor-handle exhaustion,
-#350 render-ledger overflow) were exposed, root-caused, and fixed along
-the way. Landed across `e45c95b0..af1a1ef9`. Deferred with issues/rows:
-#352 (range-watcher cylinder unit test), AP-166's pending-sell
-highlight, AP-167 (SellSingleItem's non-empty-container branch), AP-168's
-shop-stock half, Buying/Selling staging polish beyond the landed scope.
-
-This closes the pre-M4 world-interaction completion program.

-# Campaign P — Physics Retail-Feel Parity
-
-**Status:** CLOSED 2026-07-31 — final user matrix accepted; tight-gap
-clearance issue #273 and deferred restricted-house gate #274 are explicitly
-carried follow-ups.
-
-**Filed:** 2026-07-29. **Directed by the user** as a pre-vendor-management
-detour after the same-day physics/collision retail-fidelity audit. The
-world-interaction program (Slice 5, vendor browsing) resumes when this
-campaign closes.
-
-**Execution model:** Claude drives autonomously slice-to-slice. Sonnet
-subagents implement bounded chunks against this plan's specs; an Opus
-review subagent gates every slice boundary. The only user stops are
-(a) the final batched connected visual matrix, (b) a DO-NOT-RETRY
-conflict, (c) anything destructive. All the CLAUDE.md workflow rules
-apply: grep-named-first → pseudocode → port → conformance test; register
-moves in the same commit; no workarounds.
-

-
-## The parity goal (the autonomy contract)
-
-**"Retail Movement Parity v1"** — the campaign is DONE when all of the
-following are auditable-true:
-
-1. **Zero physics-scope temporary stopgaps.** TS-1, TS-4, TS-5, TS-23,
-   TS-46 retired by porting the retail mechanism. TS-24, TS-35, TS-40
-   either retired or re-classified (IA/AD) with a recorded justification.
-2. **No feel-affecting approximations left unargued.** AP-7 resolved by
-   decoding retail's friction state gate; AP-10 restored to retail's
-   0.1 m water sink-in; AP-25 replaced by the retail effective-skill
-   chain (vitae/enchantment-aware); AP-71 (`check_entry_restrictions`)
-   ported.
-3. **Issue ledger:** #262, #165, #166, #116, #167, #72, #153 closed;
-   the stale "pending visual gate" statuses on #172/#173/#174/#175/#41
-   reconciled (folded into the final matrix below). Explicitly excluded:
-   #235 (user-deferred 2026-07-27) and #256/#257 (lifecycle/memory, not
-   physics feel — separate track).
-4. **Verification:** each port carries decomp citations + conformance
-   tests; `dotnet build` + full Release suite green at every slice
-   commit; one batched connected visual matrix (below) passes at the
-   end, run by the user.
-
-Anything not in this list is out of scope for the campaign — file it,
-don't chase it.

-## Slices
-
-### P1 — Stat-coupled movement (burden / stamina / vitae) — retires TS-5, AP-25, the burden gap
-
-**Status (2026-07-30): COMPLETE.** Landed at `9355ddce`; Opus review
-APPROVE at `001e466d` (which also retired UN-8 — the CanJump polarity is
-byte-PROVEN `load < 2.0` from the PDB-paired binary — and recorded the
-PK-timer jump-cost decode for P3). Full Release suite 9,880/0/5 at the
-slice gate. Retail's vitae/enchant chain reuses the M3 bucket-4
-representation; `JumpStaminaCost` never refuses (weak-jump only) — the
-plan's formula shorthand had the `+0.5` operand wrong and the
-implementation follows the decomp's `(load+0.5)*power*8+2`. AP-127 was
-filed for the then-bounded bonus properties and retired by #268 on
-2026-07-31.
-
-Today `PlayerWeenie.SetBurden` has zero callers, `CanJump` is always
-true, `JumpStaminaCost` is 0, and pushed run/jump skill is
-attributeBonus + init + ranks only. Retail modulates movement by
-character state continuously.
-
-**Retail anchors (named decomp, verified 2026-07-29):**
- `ACCWeenieObject::{CanJump 0x0058c400, JumpStaminaCost 0x0058c440, InqJumpVelocity 0x0058c520, InqRunRate 0x0058c560, InqMaxRunRate 0x0058c5a0}` — thin delegations to the qualities DB (pseudo-C ~406512).
- `CACQualities::{InqMaxRunRate 0x00591b20, CanJump 0x00591b50, JumpStaminaCost 0x00591b90, InqRunRate 0x00592800, InqJumpVelocity 0x00592980, InqLoad 0x0058f130}` (pseudo-C ~412901–413975, ~409756) — the real load/skill/vitae composition. `InqJumpVelocity` ends in `sqrt(GetJumpHeight(...) * 19.6)` (pc 413975).
- `MovementSystem::{GetRunRate 0x006b0950, GetJumpHeight 0x006b09b0, JumpStaminaCost 0x006b0a40}` (pseudo-C ~695958) — GetJumpHeight readable: `LoadMod(load) * (skill/(skill+1300) * 22.2 + 0.05) * power / scaling`, floor 0.35; JumpStaminaCost readable: `ceil(((power + 0.5) * load) * 8 + 2)` on the arg3==0 branch.
- `EncumbranceSystem::{EncumbranceCapacity 0x004fcc00, Load 0x004fcc40, LoadMod 0x004fcc70}` (pseudo-C ~256393).
- Cross-refs: ACE `MovementSystem`/`EncumbranceSystem` C# ports; holtburger if it models load.
-
-**Work:**
-1. Port the full chain into Core (`EncumbranceSystem` + `MovementSystem`
-   statics; `PlayerWeenie` becomes the CACQualities-shaped composition).
-   Where BN x87 mush blocks a branch (GetRunRate body), use Ghidra MCP
-   or the ACE port as the tiebreaker and cite which.
-2. Determine, from `CACQualities::InqRunRate`'s own body, exactly which
-   skill level retail feeds (base vs enchantment/vitae-adjusted) and
-   port THAT — scoped to the run/jump query path only, reading vitae +
-   relevant skill enchantments from the M3 active-effect state. Do not
-   build a general effective-skill engine.
-3. Plumb the inputs from Runtime: burden (EncumbranceVal/capacity from
-   PlayerDescription + property updates), current stamina (vitals),
-   vitae. Extend `RuntimeMovementSkillState` (J4.4 seam) so updates flow
-   mid-session, same as run/jump skill today.
-4. Wire the existing `jump_is_allowed` stamina-refusal branch and the
-   `ReportExhaustion` dual-dispatch gate (R3-W4 seam) to a real
-   consumer, matching retail's refusal/weak-jump behavior.
-5. Conformance tests: formula tables (golden values incl. 800-skill cap,
-   load-mod knees at 100%/200%, stamina cost ceil), gating tests
-   (no-stamina jump refusal), plumbing tests (burden/stamina/vitae
-   changes move the produced rate). Register: delete TS-5 + AP-25 rows,
-   note the retirement in the same commit.
-
-### P2 — Response-layer edge family — retires TS-1, TS-4, AP-7; closes #166, #116
-
-**Status (2026-07-31, FINAL):** TS-1 and AP-7 retired as originally
-recorded. TS-4's first 2026-07-30 removal was accepted by an incomplete
-resolver-only fixture, failed the live matrix with a roof wedge/uphill-bounce
-regression, and was reverted. The 2026-07-31 closure began from a fresh
-`BSPTREE::find_collisions` read and ports the exact asymmetric Path-6 split:
-primary/foot hits use `SetCollide` + `LandingZ` + `Adjusted`, while
-secondary/head hits use `CollisionNormal` + `Collided`; neither writes a
-sliding normal. Both graph and prepared-flat implementations match that
-oracle.
-
-The corrective acceptance no longer calls the old horizontal-input fixture
-"production-shaped." `Ts4ProductionQuantumConformanceTests` executes the
-already-airborne, zero-root-motion 30 Hz Core collision tail — acceleration,
-body integration, transition resolve, exact body/cell commit, then
-`handle_all_collisions` — and retains its behavior-bearing cell, contact,
-sliding, stationary-fall, and velocity state for 90 ticks. Graph and flat
-match by raw bits for vertical/inward/tangential/downhill cases and a genuine
-positive-Z uphill jump; exact terminal state, non-penetration, no fixed point,
-and no second launch are pinned. No further product-code correction was
-needed after that test became faithful, and there is no active AD-56 row. The
-older resolver-only wedge test remains only as a historical three-second
-signature control. #116 shape-2 remains closed; shape-1 remains narrowed as
-recorded in its issue history. AD-55 remains retired by the raw-byte
-`cos(10°)` proof.
-
-The collision *response* layer (what happens after a hit): ground
-friction, cliff edges, downhill landings, near-perpendicular wall
-slides. One oracle-driven pass; the physics digest's DO-NOT-RETRY table
-binds every subagent here.
-
-**Work (research doc FIRST, then port):**
-1. **AP-7:** decode the state gate on retail's friction block
-   (`calc_friction` region, pseudo-C ~276702-276705) that lets retail
-   use threshold 0.25 without hammering normal locomotion (the reverted
-   L.3c attempt). Ghidra MCP for the x87 branch if BN is garbled.
-2. **TS-1:** port the `EdgeSlide → PrecipiceSlide / CliffSlide` chain
-   (precipice context, steep-plane bookkeeping) replacing our
-   stop-at-edge.
-3. **#166:** port the landing "sled" (Sledding state set/clear sites;
-   the sled friction constants already sit in `calc_friction`).
-4. **TS-4:** remove the Path-6 steep-poly shortcuts and port retail's exact
-   sphere split: primary/foot uses `SetCollide` + `LandingZ` + `Adjusted`;
-   secondary/head uses `CollisionNormal` + `Collided`. Remove every BSP-layer
-   `SetSlidingNormal` write (retail's only in-transition writer is
-   `validate_transition`).
-5. **#116:** the near-perpendicular lateral-slide loss + first-airborne-
-   frame divergence, driven by the existing tick-22760 replay and D4
-   pins.
-6. Apparatus: extend the trajectory-replay tests; capture fixtures
-   before changing behavior. Register: delete TS-1/TS-4/AP-7 rows.
-
-### P3 — Remote-object residuals — retires TS-46, TS-23; closes #165; narrows/retires AD-25
-
-1. **TS-46:** pass the Setup's verbatim sphere LIST into the transition
-   (`CPhysicsObj::transition 0x00512dc0 → init_sphere`) instead of the
-   two-scalar reconstruction, for local player and remotes; derive
-   remote step-up/step-down from the Setup instead of the pinned 0.4 m.
-   Captured-fixture replays must stay green or be re-baselined with
-   evidence.
-2. **AD-25:** align the remote post-resolve with the ported
-   `handle_all_collisions` (grounded-bounce rule) as the player half
-   already did in #182.
-3. **#165:** remotes visibly penetrate walls before stopping — diagnose
-   against the (now Setup-true) sweep; suspect list starts at the
-   catch-up step length vs sweep sub-steps.
-4. **TS-23:** parse PlayerKillerStatus from PlayerDescription/property
-   updates and plumb PK/PKLite/Impenetrable onto local + remote player
-   movers (`OBJECTINFO::init 0x0050cf30` state bits). Non-PK ACE
-   behavior must be provably unchanged.
-
-### P4 — World specials — retires AP-71, AP-10
-
-**Status (2026-07-30): COMPLETE**, including a same-day Opus review
-fix. AP-71 landed at `d6c3f865` (20 new conformance tests); AP-10 landed at
-`cc8d57a2` (12 new conformance tests). Complete solution suite at that gate:
-9,946 total across 9 test projects, 9,941 passed, 5 skipped, 0 failed on a
-clean run. One run in the same session saw a single unrelated flake
-(`AcDream.Content.Tests.Vfx.RetailDatLoaderTests
-.AnimationCache_CoalescesSameDidAndAllowsUnrelatedReadsInParallel`, a
-parallel-cache-coalescing timing test untouched by either commit) that
-passed 3/3 in isolation and on the immediate re-run — full-suite parallel
-contention, not a regression (independently fixed afterward at `dc0468cc`).
-
-**P4 review verdict: FIX-FIRST (2026-07-30).** `RestrictionObjPrevalenceInspectionTests`
-(`3b5e0992`) measured the installed cell DAT: 103,766 of 729,888 EnvCells
-across 1,293 landblocks — the entire housing estate, `restrictionObj` GUIDs
-`0x70xxxxxx` — carry a baked `RestrictionObj`. AP-71's fail-closed default
-(landed with `CanMoveInto` deliberately unmodeled, per the original AP-129
-row) would have locked every apartment/cottage/villa interior for every
-player, including its own owner — a live regression, not the "inert in dev
-content" the row assumed. Fixed at `7a0f836a`: `ACCWeenieObject::CanMoveInto`
-(0x0058da40) and `RestrictionDB::IsAllowedIn` (0x005ae8f0) are now ported
-verbatim, fed end-to-end from CreateObject's HouseOwner/HouseRestrictions/
-Monarch PWD-tail fields (previously parsed-and-discarded) plus a new live
-`House_UpdateRestrictions (0x0248)` parser, and resolved through a new
-`PhysicsEngine.Objects` property wired to the canonical `ClientObjectTable`
-in `RuntimeEntityObjectLifetime` (production fix, not just gate logic — an
-unwired table still fails closed). AP-129 is narrowed (not retired) to the
-genuine residual: no sequence-based staleness rejection for
-`House_UpdateRestrictions` (low-probability, self-correcting), and the
-outdoor `CLandCell` restriction path (a separate DAT structure) remains
-unported, unaffected by this fix. Gate: `AcDream.Core.Tests` 4,049 passed / 2
-skipped / 0 failed; `AcDream.Core.Net.Tests` 761 passed / 0 skipped / 0
-failed; complete solution suite 9,961 total, 9,956 passed, 5 skipped, 0
-failed.
-
-1. **AP-71:** port the `CObjCell::check_entry_restrictions` gate at the
-   head of `find_env_collisions` (pc:309576) — barred house cells block
-   at the threshold client-side. Landed: the gate is wired at the top of
-   the indoor branch of `Transition.FindEnvCollisions`; `CellPhysics
-   .RestrictionObj` is fed from the DAT-baked `EnvCell.RestrictionObj`
-   field (§4.3's open question resolved via ACE's DatLoader + an
-   independent `Chorizite.DatReaderWriter` reflection probe — it's a
-   plain per-cell DAT field, not a live wire override) in both the dev
-   and production caching paths, at zero bake-format cost. The mover's
-   `CanBypassMoveRestrictions` (BF_ADMIN & BF_IMMUNE_CELL_RESTRICTIONS)
-   is decoded via the TS-23 PWD-bitfield pipeline. The original landing
-   deliberately left `CanMoveInto` unmodeled (fail-closed default, filed
-   as AP-129) — the P4 review found this fails closed for the ENTIRE
-   housing estate and required the fix-first pass described above.
-2. **AP-10:** restore retail's 0.1 m water sink-in; while there, verify
-   the water-contact step behavior (`WATER_CONTACT_TS` consumers)
-   against retail and file anything found. Landed: the dry-corner
-   constant is restored (full suite green — the sticky Contact/OnWalkable
-   bit argument held); `WaterContact` is now produced at every
-   `Contact`/`OnWalkable` commit site. No confirmed retail consumer of
-   `WATER_CONTACT_TS` was found this pass; filed as #264 along with two
-   other explicitly-unverified water items (the `ENTIRELY_WATER`
-   ethereal/swim terrain-collision exemption, and jump/swim
-   movement-effects) — none block this port.
-
-**P4 review addendum (2026-07-30): APPROVED after one FIX-FIRST round.**
-The initial AP-71 landing failed closed with `CanMoveInto` unmodeled; the
-prevalence inspection (`3b5e0992`) proved that locks all 103,766 housing
-EnvCells. `7a0f836a` ports `CanMoveInto`/`IsAllowedIn` verbatim
-(owner/self/null-db admit; unresolved object blocks), captures the
-previously-discarded HouseOwner/Monarch PWD fields, parses
-`House_UpdateRestrictions 0x0248` live, and wires the canonical object
-table into the gate. AP-129 narrowed to the sequence-byte and outdoor
-RestrictionTables residuals. Suite 9,956/0/5.
-
-### P5 — Deferred fidelity — closes #167, #153, #72
-
-**Status (2026-07-30): item 1 (#167) COMPLETE.** Both blockers resolved
-without Ghidra/cdb — the two x87-elided constants were byte-decoded
-straight from the matching binary's raw machine code
-(`docs/research/2026-07-30-constraint-leash-constants.md`). The leash is
-now armed at every current acdream inbound-position acceptance seam
-(`ConstraintDistance`, `LiveEntityNetworkUpdateController`,
-`PlayerMovementController.SetPosition`/`BlipPosition`), the per-tick
-`PhysicsBody.IsFullyConstrained` push replaces the always-false stub, and
-register row TS-35 is deleted. Full Core/Runtime/App suites pass with new
-conformance tests (leash-armed jump refusal, teleport-vs-blip
-anchor/teardown, taper reduction, remote-tick push). Items 2 (#153) and 3
-(#72) remain open.
-
-1. **#167:** decode the two unknown x87 ConstraintManager constants
-   (Ghidra) and port leash arming.
-2. **#153:** the far-teleport arrival onto an unstreamed landblock near
-   a 192 m edge — apparatus first (the issue's own trigger table), then
-   the streaming-gap hold shape ALREADY sketched there (freeze the
-   per-tick resolve until the landblock loads — the async equivalent of
-   retail's synchronous load; this is an AD row, not a workaround, and
-   gets filed as one).
-3. **#72:** close on the R6 evidence (DAT-authored omega ±1.5 rad/s is
-   live; the cdb confirmation ask is obsolete).
-
-### P6 — #262 login run-on-the-spot (live defect)
-
-Probe-instrumented fresh-process login repros (`ACDREAM_PROBE_RESOLVE=1`
-+ net probes) against local ACE; the issue's hypothesis list is the
-script. Root cause, fix, regression test. No workarounds (no auto-recall,
-no synthetic position kick). Runs serialized (owns the build tree +
-client).
-
-### P7 — Ledger + camera feel
-
-1. Retire the stale TS-25 row (outbound stance ships via
-   `RawState.CurrentStyle` since #219) and refresh TS-24/TS-35/TS-40
-   classifications.
-2. #115 camera-drag: investigation-only against `CameraManager`
-   constants (AD-37's vector-nlerp vs retail quaternion-slerp is the
-   prime suspect); fix if a concrete divergence falls out, otherwise
-   re-classify with evidence.
-3. Reconcile #172/#173/#174/#175/#41 statuses via the final matrix.

-
-## Implementation-phase closeout (2026-07-30) — awaiting the matrix
-
-Every implementation slice is COMPLETE and Opus-reviewed; the campaign now
-waits on the single user gate below.
-
-**Register scorecard:** goal-enumerated physics stopgaps at ZERO — TS-1,
-TS-4 (+ its FlatBspQuery twin), TS-5, TS-23, TS-35, TS-46 retired by
-ports; TS-25 retired on #219 evidence; TS-24→AD-57, TS-40→AD-58
-re-argued. AP-7, AP-10, AP-25, AP-71 retired; UN-8 and AD-55 retired by
-raw-byte proof; AD-25 retired. AP-127 was subsequently retired by #268;
-the remaining new argued rows are AP-128/129,
-AD-53/54/55(retired)/56/57/58.
-
-**Issues:** #72, #153, #167, #255 closed; #116 shape-2 closed /shape-1
-narrowed to a probable harness artifact (response layer byte-verified);
-#165 diagnosed to the render-lag candidate (matrix scenario 8a decides);
-#166 all four composite deviations landed (scenario 5 decides); #262
-apparatus permanently live + 3/3 clean probe logins (scenario 11
-decides). Notable finds along the way: ACE's inverted leash-start
-mapping, ACE's radians/degrees sled-constant bug (cos 10°), the
-housing-lockout prevalence catch (103,766 restricted cells), and the
-HouseOwner/Monarch PWD fields that were parsed-and-discarded.
-
-**Verification:** every slice gated on the complete Release suite; final
-state 9,977 passed / 0 failed / 4 skipped (the D4 un-skip retired one
-permanent skip). Suite grew from 8,826 to 9,977 tests over the campaign
-(+1,151, all conformance/golden/pin coverage).
-
-## Final batched connected visual matrix (the ONE user gate)
-
-1. Burden >100%: run slows, jump shrinks; ~200%: barely moves/jumps.
-2. Repeated jumps drain stamina; low stamina → weak/refused jump;
-   exhaustion behavior matches retail.
-3. Fresh vitae: movement penalty present.
-4. Walk off a cliff/roof edge: slides over like retail, no dead stop.
-5. Downhill jump landing: sled glide + bounce.
-6. Shallow-angle wall graze: lateral slide preserved.
-7. Packed crowd: spacing + shuffle-out unchanged (regression).
-8. Two-client: remote stops at walls without visible penetration;
-   remote ceiling-jump bounces down immediately (#173); Holtburg portal
-   platform step-up (#172); door Use after jumping (#174); closed-door
-   collision matches the visual door (#175); observed-player blips
-   gone (#41).
-9. Locked/barred house: blocked at the threshold.
-10. Wading: slight retail sink-in.
-11. ~20 fresh logins: no run-on-the-spot.
-12. Regression sweep: walk/run/strafe/turn/jump/stairs/doors/water
-    edges feel unchanged from the accepted R6 baseline.
-
-## Risk notes
-
- P2 and P3 touch the frozen-adjacent transition internals — every
-  subagent prompt must carry the digest's DO-NOT-RETRY table and the
-  no-workarounds rule; 3 failed attempts on any item = stop and build
-  apparatus, per [[feedback_apparatus_for_physics_bugs]].
- TS-46 changes the collision capsule of every mover; the captured
-  replay fixtures pin behavior — re-baseline only with a recorded
-  retail argument.
- P1's enchantment-aware skill read is the scope-creep risk; it is
-  bounded to the run/jump query path by this plan.
-
-## Live-gate session 2 (2026-07-30) — speed + bounce family landed
-
-The matrix's first live rows surfaced three defects; all three are
-root-caused, retail-ported, and user-accepted in the same session:
-
- **#266 CLOSED** — run speed: retail `MovementSystem::GetRunRate`
-  (0x006b0950) treats 800 as an EXACT-EQUALITY sentinel; ACE's `>= 800`
-  reading is a misread of the same x87 mush that our P1 port inherited,
-  flat-lining every maxed character at 4.5 (retail-true ~3.70, +21%,
-  vitae-independent). Byte-decoded, fixed at `61e95916`; the [stat-chain]
-  live capture proved the vitae→skill chain correct end-to-end. Side-by-
-  side pace vs a retail client accepted by the user.
- **#265/#166 landing-momentum + bounce family** — two stacked fixes:
-  (1) `c60f6e5d` stopped hand-zeroing grounded residual velocity and
-  wired the never-written `GroundNormal` (roof slides restored);
-  (2) `2d611b2b` replaced the AD-25 landing adaptation with the retail
-  mechanism: `check_contact` (0x0050f5b0) transition seeding, the
-  velocity-free `SetPositionInternal` commit (0x00515330), and the live
-  5%-elasticity landing reflect (DEFAULT_ELASTICITY 0.05 @0x007c6a7c).
-  Downhill bounce chain, flat-ground pop, and clean uphill landings all
-  user-accepted ("almost pass with merits"). Investigation + byte-decode
-  record: `docs/research/2026-07-30-landing-bounce-family.md`.
- **#267 shipped** (vitae/buff panel values; attributes vitae-immune).
-  **#268 closed 2026-07-31**: the complete
-  augmentation chain is shared by panel and Runtime movement; AP-127 is
-  retired. Attributes, secondary attributes, and skills use retail's
-  vitae-excluded green/red comparison. The selected-skill footer now renders
-  per-fragment colors through the shared retained text primitive, using the
-  authored 0x1B palette exactly: #7FFFFF vitae, #00FF00 buff, #FF0000
-  debuff. TS-8 is also retired: a real live 0x02C2 payload carries its full
-  StatMod through dispatch and changes the effective skill immediately. The
-  user accepted the live colors, values, footer, and immediate row refresh.
- **#269 closed 2026-07-31** — the live 2,184-quantum trace proved the
-  landing reflect and friction math were correct. ACDream omitted retail's
-  `OBJECTINFO::kill_velocity` before restoring a remembered contact plane
-  in `CTransition::validate_transition @ 0x0050AA70`, retaining full
-  downhill velocity while repeatedly re-grounding the mover. The exact
-  non-OK-only restore/kill order and final last-known validity overwrite
-  are now ported, focused/full gates pass, and the user accepted repeated
-  slope jumps. Evidence:
-  `docs/research/2026-07-31-269-slope-stop-capture.md`.
- **#271 closed 2026-07-31** — a bounded stair-side
-  trace proved ACDream could bypass retail's current-position edge back-probe
-  by promoting a stale `LastWalkable` tread. That made PrecipiceSlide reverse
-  an uphill tangent and rapidly carry the player down the stairs. The two
-  stale-history substitutions are removed; current-walkable, back-probe, and
-  no-walkable outcomes now follow `CTransition::edge_slide @ 0x0050B3D0`.
-  The exact captured frame is pinned in the existing installed-stair fixture
-  and the complete Release suite passes 10,062 tests / 5 skips. The user
-  accepted repeated uphill runs while pressing into the stair sides. Evidence:
-  `docs/research/2026-07-31-271-stair-side-slide-capture.md`.
- **#272 complete and user-accepted 2026-07-31** —
-  `CACQualities::InqLoad` consumes enchantment-adjusted Strength through
-  `InqAttribute`, but Runtime movement and both retained burden displays read
-  raw Strength and did not share the enchantment invalidation edge. They now
-  consume `GetEffectiveAttribute(Strength)` and
-  `Spellbook.EnchantmentsChanged`, so buff, dispel, expiration, and death
-  purge recompute the same burden state immediately. Focused and full
-  Runtime/App tests pass.
-
-Matrix rows accepted so far: speed parity, roof slide, downhill bounce,
-flat pop, uphill landing, and #269's slope-stop feel
-(rows 3/4/5-partial/12-partial). The 2026-07-31 final session accepted
-burdened movement, exhausted jumping, wall/corner response, crowded-monster
-movement, two-client remote/door/portal behavior, and shallow water. The user
-waived the general sweep, deferred restricted-house validation as #274, and
-retained the separate tight-gap clearance mismatch as #273. Automated
-scenario 11 remains 20/20 passing. The #269 checkpoint passes 4,107 Core tests / 2 skips and 439
-Runtime tests / 0 skips; the complete Release suite passes 10,061 tests /
-5 skips / 0 failures.

-# Campaign P — final connected visual matrix (runbook)
-
-**The ONE user stop of the physics parity campaign**
-(`docs/plans/2026-07-29-physics-parity-campaign.md`). Run after every slice
-P1–P7 is committed and the full Release suite is green. Each scenario names
-its setup, the retail-correct outcome, and the ledger items it closes.
-Scenarios 1–3 need a burden/stamina-capable character on local ACE (use
-`@god`-style commands sparingly — see `reference_ace_commands` cautions);
-scenario 8 needs the second client.
-
-| # | Scenario | Setup | Retail-correct outcome | Closes / confirms |
-|---|---|---|---|---|
-| 1 | Burdened movement | Load the character past 100% burden (pack full of heavy loot), then ~190% | Run speed visibly drops past 100%; near 200% the character can barely move and jumps only inches | TS-5/AP-25 retirement (P1) |
-| 2 | Exhausted jump | Drain stamina (repeated full-power jumps) to near 0 | Jump cost rises with burden; at insufficient stamina the jump refuses/weakens exactly like retail (no infinite full-height jumps) | TS-5 retirement, ReportExhaustion consumer (P1) |
-| 3 | Vitae run | Die once, recover the corpse with vitae active | Run/jump measurably below the no-vitae baseline; recovers as vitae expires | AP-25 replacement (P1) |
-| 4 | Cliff edge | Walk (not jump) off a steep cliff/roof edge (Holtburg bluffs) | The body slides along/over the edge (PrecipiceSlide), never a dead stop pinned at the lip | TS-1 retirement (P2) |
-| 5 | Downhill sled | Run-jump down a long slope and land | Landing glides ("sleds") with a small bounce, then friction settles it; no instant stick | #166 close, AP-7 gate (P2) |
-| 6 | Wall graze | Run into a wall at a very shallow angle; also press into a corner and wiggle | Tiny lateral slide is preserved (no dead-stop absorb); corner shuffle-out works | #116 close (P2) |
-| 7 | Crowd regression | Stand in a packed monster camp; wiggle, jump out | Spacing and shuffle-out unchanged from the accepted #182/#184 baseline | P2/P3 regression guard |
-| 8 | Two-client remote checks | Second client (retail or acdream) observed from the first | (a) remote stops at walls without sinking in (#165); (b) remote jumping into a dungeon ceiling bounces down immediately (#173); (c) Holtburg town-network portal platform steps up (#172); (d) door Use works after jumping (#174); (e) closed-door collision matches the visual door (#175); (f) no sub-decimeter blips on observed players (#41) | #165 close + the stale #172–#175/#41 gate reconciliation |
-| 9 | Barred house | Approach a house/cell the character is not a guest of | Blocked at the threshold client-side (no enter-then-server-boot) | AP-71 port (P4) |
-| 10 | Wading | Walk into shallow water at a shoreline | Feet sink ~0.1 m into the water surface like retail; movement feel unchanged | AP-10 restore (P4) |
-| 11 | Fresh logins ×20 | 20 fresh-process logins (mix of outdoor/indoor saves) | Zero run-on-the-spot; movement immediate every time | #262 close (P6) |
-| 12 | General sweep | 10 min free play: walk/run/strafe/turn/jump/stairs/doors/portals incl. one far-town hop | Indistinguishable from the accepted R6 baseline; no new regressions | campaign regression gate; #153 connected confirmation |
-
-Rubber-band check (rides scenario 12): induce a server correction (e.g.
-brief packet-loss on Coldeve or a forced position reset) — the leash taper
-engages and jumping inside a tight leash is refused (0x47), per the #167
-port (P5).
-
-**Recording the result:** per scenario PASS/FAIL + a one-line note. Any FAIL
-reopens its slice; the campaign closes only on a clean sheet. On full pass:
-close #165/#166/#116/#262 (if not already), mark #172–#175/#41 reconciled
-with this matrix as the cited gate, update the campaign plan + roadmap +
-CLAUDE.md current-state, and flip the goal.
-
-## Automated pillars — BANKED 2026-07-30 (pre-user-session)
-
-Run on the final tree (post all Campaign P slices), local ACE:
-
- **Lifecycle/reconnect gate: PASS** —
-  `logs/connected-world-gate-20260730-130611/report.json` (seven
-  checkpoints, graceful exits). Covers scenario 12's login/portal/
-  teardown backbone.
- **Canonical nine-stop soak: PASS** —
-  `logs/connected-r6-soak-20260730-131141.report.json` (production-
-  dispatcher movement input across nine stops). Covers scenario 12's
-  movement-regression backbone.
- **Scenario 11 (20 fresh logins): PASS, automated basis** — 20/20
-  fresh-process logins (`artifacts/262-probe/login-{1..20}.log`): every
-  attempt committed the `[snap]` OUTDOOR server-Z branch, held a live
-  resolve stream (~5.3-6.0k lines/40 s), recentered correctly
-  (incidentally onto far-town 0xC95B — the #153 arrival class — all 20
-  times), and closed gracefully. No run-on-the-spot signature. The
-  user's eyes-on confirmation of "movement immediate" on a couple of
-  manual logins completes the scenario.
-
-Remaining for the user session: scenarios 1-10 (feel/visual) + the
-manual halves of 11-12.
-
-## User matrix session 1 results (2026-07-30, partial)
-
- Scenario 4/5 (cliff/sled): **FAIL** on the TS-4-removed build — uphill
-  jump-in bounces (non-retail), roof slides lost, occasional edge wedge.
-  → TS-4 removal REVERTED (`2e27d066`+`a8a7d64b`), row re-opened with
-  live evidence; downhill sled remains #166. Re-test pending.
- Speed parity: **FAIL/SUSPECT** — local char faster than retail
-  comparison → #266 (controlled capture needed).
- Vitae panel display: **FAIL** (UI, not physics) → #267.
- Squeeze-through at the townhall building: **FAIL** → recorded under
-  scenario 12; needs a dedicated capture (suspect list: TS-46 sphere-list
-  threading at a specific site, or the #116 head-sphere change — both
-  P3/final-slice deltas).
- Other scenarios: not yet reported.
-
-## User matrix session 2 results (2026-07-31)
-
- Scenario 1 (burdened movement): **PASS**.
- Scenario 2 (exhausted jumping): **PASS**.
- Scenario 6 (wall graze/corner movement): **PASS**.
- Scenario 7 (crowded-monster movement): **PASS**.
- Scenario 8 (two-client remote movement, doors, portals, and its collision
-  checks): **PASS**.
- Scenario 10 (shallow-water sink-in): **PASS**.
- Scenario 9 (restricted/barred house): **DEFERRED BY USER** and retained as
-  issue #274.
- Scenario 12 (general movement sweep): **WAIVED BY USER**; the accepted
-  focused rows and existing automated soak are sufficient for this campaign.
- A separate live mismatch remains: acdream can squeeze through some tight
-  gaps that block retail. This is outside the accepted wall-graze response
-  check and is retained as issue #273 pending an exact-location capture.
-
-Together with the previously accepted scenarios 3–5 and the automated
-20-login scenario 11, the Campaign P matrix is closed with #273 and #274 as
-explicit carried follow-ups.

-# Placement production cutover — campaign plan (2026-08-02)
-
-> ## ✅ CAMPAIGN LEDGER CLOSED — 2026-08-06, by user direction
->
-> Every slice is landed and dual-reviewed: **C0–C4**, **C5a**, **C5b**
-> (#275; retired AP-131 + AD-60's legacy half), **#280** (portal destination
-> prefetch, user-accepted at its connected gate), **#276's remainder**,
-> **AP-22** and **AD-10** (both retired). **#309** was accepted as a standing
-> divergence rather than fixed. Final gate: complete Release suite from a
-> clean build, **11,196 passed / 4 skipped / 0 failed** — campaign net +90
-> from 11,106.
->
-> **The ledger closes with connected gates outstanding, by user direction —
-> not because they were discharged.** Only #280's reveal gate was run and
-> passed. D-1's two reachability scenarios, AP-136's six-step park protocol,
-> route-7 thickening, the two-client observation, the nine-stop soak and the
-> lifecycle/reconnect route were **NOT RUN**; the probe family is
-> **deliberately NOT stripped** for that reason. Anyone citing "the campaign
-> passed" must cite §2.6 of the closeout alongside it:
-> [`2026-08-06-c5c-closeout-handoff.md`](../research/2026-08-06-c5c-closeout-handoff.md).
->
-> Follow-ups generated and filed rather than folded in: **#325**, **#330**,
-> **#331**, **#332**, **AP-149**, **AP-152**, **AD-65**, **AD-66**. Start with
-> **#331**.
-
-The final leg of the remaining physics-divergence campaign before AP-22 and
-AD-10: route graphical AND headless production placement through the
-residence + continuation-executor owner (`38fd4b8d` / `30012361` /
-`5db3de3c`), delete the legacy duplicate authorities, and retire AP-1/AD-1
-behind connected + user-visual gates.
-
-## Handoff checkpoint — 2026-08-03
-
-**Status: stabilization checkpoint accepted; campaign closeout is not yet
-complete.** The C3c production cutover and the O(changed) collision
-publication checkpoint are now playable after five separately committed
-root-cause fixes:
-
- `01f4791e` stops origin recenter from manufacturing and replaying a second
-  retirement receipt for a pending-only live-projection bucket. Its exact
-  binary passed the complete Release suite, lifecycle route, and canonical
-  nine-stop soak (`connected-r6-soak-20260802-204309`, nine stops, zero
-  failures/wait cues/pending retirements).
- `670f307c` keeps remote Create placement, the local-player physics host,
-  targeting, chasing, and attacks in the same world-coordinate frame. The
-  user accepted monster placement/chase/hit behavior and static placement
-  after portals.
- `1fc529cd` materializes the canonical minimal static physics host before a
-  distant Use/MoveTo route and reconciles the pre-PartArray startup motion
-  suffix. The user accepted near and distant object use.
- `f24532ad` defers one-shot F754/F755 effects until canonical placement has
-  bound presentation, retries projectile/static-animation sidecars on the
-  committed visibility edge, and keeps effect cells synchronized. The user
-  accepted buffs, recalls, arrows, combat spell projectiles, portals, and
-  static animation.
- `175ad6b0` sends LoginComplete from the local first-placement terminal edge
-  instead of raw PlayerCreate receipt, so ACE's intentional login Hidden/
-  materialization state cannot race placement. The user accepted the login
-  haze behavior.
-
-Focused verification after the final fix passed 90 App effect/projectile/
-static-scheduler tests, two Runtime login tests, the exact live-entity cell
-tracking regression, all 79 Headless tests, and the Release solution build
-with zero errors. The long connected soak and complete solution suite have
-**not** been rerun on the final `175ad6b0` binary. A broader selected fixture
-run also exposed five `LiveEntityRuntimeTests` failures tied to the still-open
-placement cutover plus one old remote first-entry fixture that supplies an
-empty collision source; classify and fix those before claiming C5 closure.
-**Resolved 2026-08-03 as #281 (DONE):** the "six selected fixture failures"
-figure was itself a mis-measurement — the measured baseline found **43**
-(28 App broken by `670f307c`, 2 more by `f24532ad`, 13 Runtime) — repaired
-without weakening assertions (`6dcb94ac`, `98e9f9e8` and the recent-regression
-cleanup closed at `2ef02f8c`); every later checkpoint's complete suite ran
-0-failed.
-
-Remaining campaign work, in order:
-
-1. Reproduce and repair the six fixture failures without weakening their
-   assertions or adding compatibility bypasses. **DONE 2026-08-03 (#281 —
-   the real count was 43; see the correction above).**
-2. Finish C4's routes 2–7 and remove their legacy placement writers; fold in
-   #276 and #277 where their route becomes authoritative. **DONE 2026-08-05
-   except the four owed connected gates (see the C4 slice below). #276 was
-   folded only PARTIALLY — route 5 closed its projectile half; the
-   `SpawnPlacementSettler` settle-cell discard remains OPEN. #277 was NOT
-   folded: no streaming/broadcast radius changed, so its service-window
-   conversion remains a trigger-conditioned carry, not a completed item.**
-3. Resolve #280 with retail's configured destination-prefetch window so the
-   portal viewport never reveals visibly constructing far terrain.
-   **DONE 2026-08-05 (implementation + suite); the connected/visual gate is
-   batched into C5's matrix. Shape correction: retail has NO separate prefetch
-   window** — it has one landscape square (`LScape::mid_radius`) that is
-   simultaneously the loaded, drawn and blocked-on set, and whose configured
-   value is `Render.LandscapeDrawDistance`. acdream now derives its reveal
-   window from the live streaming radii (`QualitySettings.FarRadius`) and made
-   the render-completeness predicate tier-aware so the outer rings can satisfy
-   it. Contract: [`2026-08-05-280-contract.md`](../research/2026-08-05-280-contract.md).
-   Residual filed as AP-149; the missing user-facing Viewing Distance option is
-   filed separately as #326 and is explicitly NOT part of #280.
-4. Run C5's complete Release suite, lifecycle/reconnect route, latest-binary
-   nine-stop soak, two-client observation, and the remaining #269 slope-glide
-   visual check. A pass from `01f4791e` is evidence for that fix, not a
-   substitute for the final-binary soak. **Correction 2026-08-05: #269 was
-   already closed and user-accepted 2026-07-31 (before this plan was

-   **DONE except the ledger close, 2026-08-05/06.** AP-1/AD-1 retired at C5a
-   (`6921a027`); AP-131 and AD-60's legacy half at C5b (`735f0a72`); **AP-22**
-   retired at `bc4679cd` (all three invented-cylinder copies deleted — the row
-   listed one; reachability proved zero over all 5,935 installed Setups by four
-   independent decoders); **AD-10** retired by deletion at `886333a2` (its
-   stated justification was false at HEAD — remotes DO run the sweep, so the
-   projection was an extra non-retail layer, measured bit-identical when
-   removed). Both dual-reviewed, both lenses PASS. Remaining: C5c's gates and

-
-## Confirmed pre-cutover gaps (from the inventory)
-
- The executor publishes only generic entity deltas; nothing bridges its
-  completion to `RuntimePlacementProjectionChannel`, so no host can learn
-  "my initial placement committed" through the built observer seam.
- No atomic controller/body publication owner exists (prerequisite C);
-  App and headless hand-write divergent `PlayerMovementController`
-  construction, and `SubmitPreparedPlacement` requires a canonical
-  `PhysicsBody` that nothing currently publishes atomically.
- The dormant placement path's 1,880 B/operation (2,048 cap) allocation
-  remains the activation blocker for frame-frequency routes.
- `Execute`'s live inputs (`UsePositionFromServer`, `PlayerDistance`) are
-  computed by no host; they must derive from Runtime's own character-option
-  and local-player owners.
- `RuntimePortalPlacementAuthority` has zero producing call sites; the
-  adapter from `RuntimeWorldTransitState` does not exist.
-  **Corrected 2026-08-04 (C4 route 3 closure,
-  `docs/research/2026-08-04-c4-route-3-contract.md`), itself corrected
-  2026-08-05 (A10 architecture review — the first correction asserted a
-  false fact of its own), and rewritten 2026-08-05 (N5 retail-review
-  round-3 fix — the prior wording of this correction contradicted
-  itself).** The original bullet conflated two separate claims into one
-  sentence, and only one of them was true. What pre-dated route 3 and WAS
-  accurate: the `RuntimePortalPlacementAuthority` type existed (referenced
-  by route 2's `Pending.Portal` field, always `Present: false`), its
-  `IsValid` check existed, and the sinks' portal-authority gates plus
-  `BeginAcceptedPlacementCore`'s gate already read it. What was NOT
-  accurate, and is what "zero producing call sites; the adapter does not
-  exist" actually described: the PRODUCER half — nothing built a
-  `Present: true` authority and called the consumer arm
-  (`RuntimeAcceptedPositionDriveController.TryExecuteAcceptedPortalArrival`/
-  `SubmitAndResolvePortal`/`ClassifyPortalArrival`) — that consumer arm
-  ALSO did not exist before route 3. Route 3 added the producer and the
-  consumer together, in the same slice: the producer is
-  `LocalPlayerTeleportController.TryExecuteCanonicalPortalPlacement` (now
-  `TryAdvancePortalCommit`/`TryExecuteCanonicalPortalPlacementCore`, per the
-  2026-08-05 A1 review fix), which builds the authority from
-  `WorldRevealCoordinator`/`RuntimeWorldTransitState` facts and calls
-  `TryExecuteAcceptedPortalArrival`; the identical Runtime entry point is
-  shared by the headless host. So: the type/`IsValid`/consumer-gate facts
-  pre-dated route 3 and were true before it; the arm (both the producer
-  that builds a live authority and the consumer that reads one) did not
-  exist before route 3 and is what the original bullet's "zero producing
-  call sites" language was pointing at.
- The exact-Setup mover chain (`PrepareMover` /
-  `RuntimeSetPositionMoverPreparer.TryBuild` /
-  `IPreparedCollisionSource.ReadSetupCollision`) exists piecewise, unwired.
- **Corrected 2026-08-04 (C4 route 6 closure,
-  `docs/research/2026-08-04-c4-route-6-contract.md`): all three clauses
-  above were stale.** Route-6 split-recovery does NOT need an effect-replay
-  suppression signal — that premise was unsubstantiated; acdream's only
-  create-time effect replay is the F754/F755 queue drain keyed by server
-  GUID, and the one plausible mechanism (a cloned `DefaultScriptType`
-  surviving `BuildSpawn`) never fires at create in either client
-  (`CPhysicsObj::play_default_script @0x005132B0`/`@0x00513300` has exactly
-  two callers, both animation hooks, verified against
-  `acclient_2013_pseudo_c.txt`). Route-7's `TryCommitParent`/
-  `CommitWithdrawal` cancellation-symmetry fixes and host-visible
-  cancellation receipts were BOTH closed at C0 (see the C0 slice below).
-  What actually remained for route 7: the child's canonical cell had two
-  writers (Runtime committed it cell-less unconditionally in
-  `CommitAcceptedParentCellless`, while `EquippedChildRenderController
-  .TickChild` re-celled it from a per-frame render tick), and headless had no
-  `EquippedChildRenderController` at all, so every headless parented child
-  stayed cell-less forever — the same defect seen from two sides, not two
-  separate gaps. **Closed 2026-08-04
-  (`docs/research/2026-08-04-c4-route-7-contract.md`).** Runtime is now the
-  sole canonical writer: `CommitAcceptedParentCellless` completes retail
-  `set_parent`'s attach-time re-cell (D1), and every canonical cell write
-  funnels through one directory chokepoint that recursively propagates to
-  committed children on every parent cell crossing (D2 —
-  `docs/research/2026-08-04-retail-parent-cell-propagation.md`), not only at
-  attach. `TickChild` is demoted to a presentation-only draw-bucket move
-  (D4); the headless host gained its own parent-realize drive running the
-  same commit pair the graphical host does (D5,
-  `RuntimeLiveEntitySessionController.OnParentUpdated`). The direct headless
-  regression test (a bot with an equipped item shows the child's canonical
-  `FullCellId` equal to the parent's) now passes.
-
-## Slices
-
- **C0 — Runtime bridge + live inputs — COMPLETE at `67f63e85`
-  (2026-08-02, dual reviews PASS).** The executor publishes an
-  acknowledge-only `ExecutorCompleted` receipt through the one placement
-  stream (registered before dispatch; correlation reaped on
-  acknowledgement/discard/clear; `PendingCompletionReceiptCount` in
-  `IsConverged`); all three production sinks acknowledge-and-ignore the
-  kind via early returns proven behavior-preserving for every other kind
-  (sanctioned seam completion — provably inert, no production publisher);
-  `UsePositionFromServer` derives retail-exactly from
-  `RuntimeCharacterState.AutonomyLevel != 2` and `PlayerDistance` from the
-  live movement controller with null-safe fallback to the caller struct;
-  `TryPrepareAndSubmitAuthoredPlacement` chains the prepared-collision
-  Setup read through `PrepareMover` to submission with zero validation
-  changes; `TryCommitParent`/`CommitWithdrawal` gained the sibling
-  cancellation flow (the `LeaveWorld` omission in `TryCommitParent` is
-  retail-REQUIRED per `set_parent` 0x00515A90:283832-283833's single gated
-  `leave_world`). Not fully dormant by design: the two cancellation fixes
-  change live Runtime paths production already calls; everything else has
-  no production caller.
-  **C3 prerequisites recorded from C0's reviews:** (a) the completion
-  receipt/trace surface is internal-only — C3 must define the public host
-  consumption shape when it wires the hosts; (b) `PlayerDistance` is
-  resolved once per `Execute` entry, not per continuation — a multi-Position
-  FIFO classifies later entries against entry-time distance (documented
-  deferral; refine at C3/C4 if the connected gates show it matters);
-  (c) any future host exposure of `TrySetAutonomyLevel` must carry retail's
-  `SendAutonomyLevelEvent` (699550).
- **C1 — atomic controller/body publication — SATISFIED BY EXISTING
-  MECHANISM (research finding 2026-08-02, plan amended same session).**
-  `RuntimeLocalPlayerPhysicsPublicationState` (1,033 lines) plus the
-  ~15-method dormant local-activation family on `RuntimeSetPositionState`
-  already implement the full sanctioned option-2 transaction:
-  off-canonical preparation against a scratch quantum clock and a sealed
-  candidate controller, one validated atomic Commit, and a staged
-  Evaluate/Commit/FinalizeActivation chain re-validated against
-  PhysicsOwnershipEpoch/ObjectClockEpoch/ControllerOwnershipEpoch/session
-  identity at every entry — with zero production callers. See
-  [`2026-08-02-canonical-body-writer-map.md`](../research/2026-08-02-canonical-body-writer-map.md)
-  (6 canonical body writers; the two host escape hatches; both hosts'
-  divergences). The remaining work — routing both hosts' local-player
-  construction through the publication lifecycle, sealing the public
-  `RuntimeLocalPlayerMovementState.Controller` setter, retiring App's
-  direct object-clock bypasses, and containing headless's uncaught
-  prepared-collision `InvalidDataException` — IS the C3 route-1 flip and
-  moves there. No separate C1 commit.
- **C2 — placement allocation budget — COMPLETE at `63c601ff`
-  (2026-08-02, dual reviews PASS after two fix rounds).** 2,032 → 944
-  B/op via pooled operation envelopes (bounded, reset-at-rent, double-
-  retire guarded, reset/dispose-cleared, ledger-visible), a cached
-  collision-callback delegate over an explicit context stack, and a
-  non-boxing pending-head read; gate tightened to 1,536. The pooling
-  forced a class-wide staleness rework: captured-token-vs-fresh-lookup at
-  every reentrancy-spanning frame (26-site audit), hoisted stack locals
-  for retail's handle_all_collisions bits, token-gated bookkeeping
-  writes, and a deliberately identity-agnostic settle path (retail's
-  SetPositionInternal completes unconditionally even for displaced
-  operations).
-  **Residual floor (documented at the gate, decision deferred to the C3
-  activation gate where the user is in the loop):** ~520 B/op inside
-  Core's `PhysicsEngine.SetPosition` (transition init / query-footprint
-  materialization — a potential C2b if C3's connected profile shows it
-  matters) and ~208 B/op of sorted-tree node per pending receipt.
-  **Maintenance notes from review (no action):** the no-reentrancy
-  proofs on the 15 surviving reference-based currency checks are
-  comment-enforced; `IsCurrent(Operation)` remains available and a new
-  reentrancy-spanning call site would silently inherit the tautology —
-  its doc comment warns.
- **C3 — spawn-frequency cutover: routes 1 + 8 — DECOMPOSED 2026-08-02
-  after the first implementation pass stopped with findings.** C3-1 (the
-  public executor-completion surface via
-  `RuntimePlacementProjectionChannel.TryGetInitialCreateCompletion`)
-  landed separately. Two structural gaps halted the flip, both real and
-  neither in the planning docs:
-  **(B)** the local player's residence lease opens its SetPosition
-  operation at Create time, but `SubmitPreparedPlacementCore` requires a
-  pre-existing canonical body that only the zero-caller publication chain
-  can attach — first-entry needs an explicit resumable sequence
-  (begin-placement → publication Prepare/Commit attaches the body →
-  authored-mover submit → Place receipt → Execute), which matches the
-  campaign handoff's route-1 required order but exists nowhere as a
-  driveable state machine;
-  **(C)** ordinary remote-creature Creates classify to `SetPosition` but
-  have NO production body-construction path at Create time (bodies arrive
-  with first motion today; retail constructs physics at CreateObject via
-  `ACCObjectMaint::CreateObject`/`set_description`, which our retail
-  notes fully document — the defaults come from the wire PhysicsDesc,
-  not invention).
-  Sub-slices, each with the standing contract/dual-review/gate
-  discipline:
-  - **C3a — Runtime first-entry sequencing — COMPLETE at `960373df`
-    (2026-08-02, dual reviews PASS).** `RuntimeLocalPlayerFirstEntryState`:
-    five stages (mover-prep → publication Prepare/Commit → activation →
-    acknowledgement → Execute) in retail's own order — mover shapes
-    BEFORE placement, matching makeObject/set_description preceding
-    enter_world; the original contract prose had it backwards and the
-    tested preconditions forced the faithful order. Acknowledge-stage
-    authority discrimination, automatic convergence through the (now
-    multicast, snapshot-iterated) retirement fan-out, ownership-ledger
-    fold, transactional late-bind Publication seam. Dormant: C3c's first
-    act is the GameRuntime binding + production Advance drive.
-    **Carried findings for C3c:** the controller is live from the
-    activation commit onward (abandonment leaves it to ordinary entity
-    teardown — retail has no entry-flow rollback); EvaluateActivation's
-    post-commit DeferredCell overload is encapsulated behind Advance.
-  - **C3b — remote body construction at Create — COMPLETE at `0934a121`
-    (2026-08-02, dual reviews PASS).** `RuntimeRemoteBodyDescription` +
-    `RuntimeRemoteFirstEntryState`: the full `set_description` order with
-    the byte-certain gates (friction [0,1] inclusive, NaN sanctioned-skip;
-    elasticity clamp with retail's unordered-to-zero; translucency
-    != 0.0f), the movement-branch discriminator on retail's
-    `movement_buffer != 0` (empty-buffer → placement branch, no autonomy),
-    motion-table zero-id pass, ctor-defaults for absent wire fields, and
-    never-clobber coexistence with the build-at-first-motion production
-    path. The acknowledge discriminator is one shared body
-    (`RuntimeFirstEntryAcknowledgement`) for both conductors. Dormant.
-  - **C3c — the host flips (production) — COMPLETE at `529e0e9d`
-    (2026-08-02, dual Opus reviews: initial FAIL 2+2 MAJOR → R1 fix
-    round → delta PASS both).** Both hosts register initial Creates
-    through residence + conductors via the shared
-    `RuntimeFirstEntryDriveController`; Controller setter sealed;
-    rebucketing presentation-only strictly while the residence is
-    ACTIVE (post-residence entities take the full legacy path including
-    the `prepare_to_enter_world` clock edges); content-less headless
-    keeps pre-flip direct registration. Five fix slices landed inside
-    the cutover, each connected-gated: F1 (Runtime ownership seam for
-    movement stats/server physics — the post-logout retired-controller
-    crash), F2 (the login activation wedge: admission-prefix gate
-    factored from the seal, rearm generation identity, auto-entry
-    requires the published controller), F3 (landblock-prefix 0-sentinel
-    → explicit absent-id; corner landblocks legal), F4 (diagnosis only:
-    the nine-stop soak's convergence failure is pre-existing `6b28ff99`
-    whole-world collision-clone throughput — its fix is the next slice
-    before C5), F5 (local-player first-entry ground contact via the
-    shared `SpawnPlacementSettler` at `FinalizeActivation`; the
-    standing-cast airborne rejections are gone; register AD-61). R1
-    additionally armed the login constraint leash at the committed
-    placement (`HandleReceivedPosition` 0x00453FD0 analog) and
-    refreshed AD-42. Final gates: complete solution 10,816/0/4 skips;
-    lifecycle/reconnect gate PASS (`connected-world-gate-20260802-
-    175401`). Closeout:
-    [`2026-08-02-c3c-cutover-closeout.md`](../research/2026-08-02-c3c-cutover-closeout.md).
-    **Carried to C4/C5:** route-1 far-Create service-window conversion
-    if either streaming/broadcast radius changes (#277); the
-    window-departure park narrowing; `NotifyRetirement`-on-active-entry
-    subscriber invariant; the reachable equip-mid-conductor fail-fast;
-    settle-CellId discard (#276-adjacent, see ISSUES).
- **C4 — remaining routes: 2 (ForcePosition), 3 (portal, with the
-  `RuntimeWorldTransitState` → `RuntimePortalPlacementAuthority` adapter),
-  4 (remote Create/Position; delete `RemoteTeleportController`/`Placement`
-  and the inline MoveOrTeleport duplicate), 5 (projectile authoritative),
-  6 (drops + split-recovery marking), 7 (residual pickup/parent/delete
-  polish). — route 2 COMPLETE AND USER-ACCEPTED 2026-08-03 (`9966b531`);
-  routes 3/4/5/6/7 remain OPEN.**
-
-  **C4 IMPLEMENTATION COMPLETE 2026-08-05.** Every route now places through
-  the canonical Runtime owner; the campaign's remaining C4 debt is exactly
-  the four owed connected gates listed at the end of this bullet. Per-route
-  record (each with contract + independent dual reviews per the standing
-  discipline; suite counts measured, never inherited — final complete
-  Release suite **11,090 passed / 4 skipped / 0 failed** at `e0f96a55`):
-  - **4a LANDED `44830a0e`; 4b-1 LANDED `2e8e09ac` (dormant
-    infrastructure); 4b-2 LANDED `7f1c1f5a`** (recorded in the sub-bullets
-    below with its four fix rounds and user-passed far-snap gate).
-  - **4b-3 LANDED `6dc7ba51` (2026-08-04)** — remote teleport + cell-less
-    through the canonical placement; `RemoteTeleportController` (605 lines),
-    `RemoteTeleportPlacement` (85), and ~1,709 test lines deleted. Dual
-    round 1 FAIL/FAIL → round 2 delta PASS/PASS; three NPC-arm MAJORs
-    closed. **Connected gate PASSED-partial (`21cd6e9b`)**: 16
-    `[remote-teleport]` probe lines over 7 creatures, all
-    `cause=teleport-ts` — `cause=cellless` was never observed and remains
-    test-covered only (owed gate 4 below). Docs at `8c269ad1`; findings
-    chain in `2026-08-04-c4-route-4b-3-*.md`.
-  - **Route 5 LANDED `36255af0` (2026-08-04)** — projectile authoritative
-    placement (#276 partial), preceded by a mandatory byte-decode gate
-    (`MoveOrTeleport` @0x00516330 never reads its velocity argument, which
-    also spawned #317). Three dual review rounds closing 8 MAJORs; round 3
-    retail PASS with the AP-141 risk-column retraction (C1), architecture
-    FAIL on a coverage-only C1 closed in-commit with two sabotage-verified
-    retry-arm tests. **NO connected gate exists for this route, by
-    design** — ACE never sends a missile UpdatePosition
-    (`WorldObject_Tick.cs:333-334`); every proof is deterministic-test-gated
-    and recorded as such. Interim landings alongside: the OnPosition
-    dual-tail collapse (`edc911b0`, whose scoping found and filed #316),
-    #315 closed (`aaf0811f`), #314 closed (`daef7c98`).
-  - **Route 6 CLOSED `1b484937` (2026-08-04) with ZERO production lines** —
-    C3c had already flipped both drop flavours onto the canonical create
-    transaction; the landing is 7 sabotage-verified coverage tests, the
-    retail split-marking record (#313 filed for the `DeclareValid`
-    selection transfer), and the correction of this plan's own false
-    effect-replay premise (see the corrected gap list above). Its coverage
-    tests immediately found #314 (split recovery threw on retained
-    timestamps), fixed in its own commit `daef7c98`. **Connected gate owed**
-    (drops recipe — owed gate 1 below).
-  - **Route 7 LANDED `cd3129e9` (2026-08-04)** — child cell propagation
-    moved from a render tick into Runtime: retail `set_parent`'s attach-time
-    re-cell completed in `CommitAcceptedParentCellless`, the recursive
-    parent-cell-crossing propagation at the one directory funnel (iterative
-    worklist — the initial depth-64 cap was deleted after both round-2
-    reviews independently found its truncation residue was the #184 shape),
-    `TickChild` demoted to presentation-only, the headless parent-realize
-    drive added (its direct regression test failed before this work), and
-    the dead `ClassifyLeaveWorld` family deleted. Dual round 1 FAIL/FAIL →
-    round 2 delta PASS/PASS plus a coordinator-required third pass; 5
-    MAJORs. AP-142/AP-143 filed. **Connected gate owed** (equip/carry with
-    `cause=propagate` probe evidence — owed gate 2 below). Route 7 also
-    INVALIDATED 4b-3's recorded cell-less live recipe (contract §11; the
-    supersession note is appended to the 4b-3 contract).
-  - **Route 3 LANDED `e0f96a55` (2026-08-05)** — the LAST route: the first
-    production `RuntimePortalPlacementAuthority` producer, the portal arm on
-    route 2's drive controller, `CommitCanonicalTeleportFrame` with the
-    `PlayerTeleported` port (autorun cancel + one movement event), and both
-    duplicate authorities deleted (`LocalPlayerTeleportPlacement.Place`,
-    `ResynchronizeLocalPlayerForPortalArrival` — AD-42's row deleted with
-    them). Contract at `19ebf043`; scoping/propagation research at
-    `ca96ea5e`. Dual round 1 FAIL/FAIL → dual round 2 FAIL/FAIL (near miss)
-    → round-3 fix pass accepted per both round-2 reviews' explicit pass
-    conditions; the round-3 record is the commit message plus #318 and
-    AP-144/AP-145 (no standalone round-3 review doc). The fix pass's
-    refusal to accept 7 skipped tests uncovered a real production bug (the
-    canonical portal arm was 100% dead code — the accepted-destination slot
-    it re-read at Place time was already consumed at Aim time). **Connected
-    gate owed** (portal/recall with `[local-tp]` probe evidence — owed gate
-    3 below — and explicitly NOT scored as covering #318).
-  - **The four owed connected gates**, with recipes and pass criteria in
-    [`2026-08-05-c4-closeout-handoff.md`](../research/2026-08-05-c4-closeout-handoff.md):
-    (1) route 6 drops; (2) route 7 equip/carry across landblock boundaries,
-    counted only with `[child-cell]` `cause=propagate` lines; (3) route 3
-    portal/recall, counted only with `[local-tp]` lines, not scored against
-    #318; (4) 4b-3's `cause=cellless` case, whose recorded trigger route 7
-    invalidated — the replacement provocation is UNESTABLISHED and needs its
-    own investigation. None has been run.
-  **Route 4 SPLIT into 4a and 4b (user-directed 2026-08-03).** Scoping
-  ([`2026-08-03-c4-route-4-scoping.md`](../research/2026-08-03-c4-route-4-scoping.md))
-  put whole-route 4 at 1,500-2,500 production lines against a stated ~400
-  budget, so it is split to keep each landing reviewable:
-  - **4a — the steady state.** The classifier's `Interpolate` (contact,
-    `PlayerDistance < 96 m`) and `NoPositionOperation` (no contact) branches.
-    NEITHER runs a `SetPosition`, so 4a has no deferred-cell park, no
-    service-window work, and no placement-allocation exposure. Fixes two of the
-    three unfiled divergences (the NPC airborne hard-snap that ignores the wire
-    `IsGrounded` bit; `ConstrainTo` armed before the operation instead of
-    after). Highest visible value — this is what makes creatures move smoothly.
-  - **4b — the edges.** `SetPosition` / `SetPositionSimple`: teleport, far-snap
-    (>= 96 m), and cell-less first placement. This is where the parks, the
-    Position-time service-window guard, #277's broken bound, N3 (headless never
-    calls `RetryPending`), and the third divergence (`ConstrainTo` never armed
-    on the remote teleport branch) all live.
-
-    **4b also inherits 4a's ownership remainder — scheduled here, not implied
-    by code comments.** Two independent reviews flagged that 4a satisfies
-    contract items 1 and 2 only partially, and the plan must carry that rather
-    than leaving it in `// 4b deletes this fallback` comments:
-    - Runtime owns the classification, the request construction (one shared
-      builder, `RuntimeAcceptedPositionRouteRequests`), the near-InterpolateTo
-      decision with AP-87, and the post-operation `ConstrainTo`. **App still
-      owns** branch selection, the airborne early return, the
-      `RemoteMotion.CellId` write, the `WorldEntity` pose write, and the
-      collision-shadow publish — all in `LiveEntityNetworkUpdateController`.
-    - Item 2 ("both hosts drive the identical Runtime entry point") is
-      satisfied only VACUOUSLY: `RuntimeLiveEntitySessionController` returns
-      early for remotes, so no no-window host exercises this path at all and
-      nothing can diverge yet. That stops being true the moment a headless
-      host needs remote motion.
-    - Every legacy fallback 4a deliberately left in place is 4b's to delete:
-      the pre-operation unconditional `ConstrainTo`, the player arm's
-      `!update.IsGrounded` no-op, the player and NPC legacy near/far routing
-      (each still carrying its own duplicate `96f` / `4f` constants), and the
-      airborne-precedence carve-out
-      (`LiveEntityNetworkUpdateController.ApplyRemoteContactRouting`) that
-      keeps a landing body snapping. Retiring the last one is a real behaviour
-      decision — retail makes no player/NPC distinction there — and needs its
-      own live evidence, not a silent convergence.
-    - Register row **AP-135** (the airborne no-op's retained acdream
-      bookkeeping: the server cell id for the free-fall sweep gate, and the
-      last-server-position sample) — **CORRECTED 2026-08-04: this row does NOT
-      retire with 4b.** Its own stated condition is retirement together with the
-      free-fall sweep gate (`RuntimeRemotePhysicsUpdater.cs:342`), which 4b does
-      not touch, and its sites are the airborne no-op branches — 4a-owned
-      dispositions, not 4b's far-snap/teleport/cell-less. The trap is that those
-      two writes sit physically inside `OnPosition`, which 4b rewrites heavily,
-      so an implementer will assume they go. They stay. See
-      [`2026-08-04-c4-route-4b-scoping-and-split.md`](../research/2026-08-04-c4-route-4b-scoping-and-split.md).
-    - **4b is itself split into 4b-1 / 4b-2 / 4b-3** (2026-08-04). Scoping put
-      4b at 1,300-2,200 production lines — 4-6x route 4a — plus ~2,500-3,500
-      lines of test work. 4b-1 is infrastructure with no remote behaviour change
-      (the per-entity placement owner, the service-window guard, the
-      refuse-rather-than-park policy, N3's headless `RetryPending` pump); 4b-2 is
-      the far branch alone; 4b-3 is teleport/cell-less and the ~739-line class
-      deletions. 4b-1 stays a separate landing regardless: it is where the
-      park-withdraws-the-entity failure mode is decided, and it must not be
-      reviewed alongside a large deletion.
-    - **4b-2 LANDED at `7f1c1f5a` (2026-08-04); far-snap connected gate
-      USER-PASSED same day.** Four fix rounds, eight Opus reviews; the slice was
-      fully green at 10,990 / 10,997 / 11,004 while containing real defects
-      (a frozen remote pinned as correct by its own test; a fallback that
-      over-wrote on the exact retail paths that decline to store; a park guard
-      incomplete on two independent axes). Final suite 11,009 / 4 / 0 against a
-      **measured** 10,968 baseline — the 10,973 figure used earlier was wrong.
-      Its real yield was a defect under routes 1 and 2, not the far snap:
-      `ParkDeferred`'s quiescence parks withdrew the entity and were never
-      restorable while `Forget(restoreCancelledPark: true)` runs for every
-      accepted Position on every entity. The restorable decision now lives
-      inside `ParkDeferred` after `SnapToCell`, read against every live
-      quiescence.
-      **Still outstanding: #309.** The `ACDREAM_PROBE_PARK=1` capture from the
-      accepting session shows 11 parks, all `cause=unplaceable` — zero
-      quiescence-cause parks, so the shared-core park change is NOT yet
-      connected-verified. Without the probe that session would have been
-      recorded as a pass. **Re-scoped 2026-08-04: #309 is largely superseded
-      by #312 (closed `b1f914d5`, user-passed); what survives is the narrow
-      `GotoLostCell` half — retail keeps a lost-cell object hidden until
-      `reenter_visibility`; acdream re-shows it on cancel. Re-scope before
-      running it.**
-      Process lesson recorded: the round-1 defect was caused by the contract
-      omitting "and still advance the pose", and the park defect should have
-      been split into its own slice the moment it surfaced in round 2 instead
-      of riding inside 4b-2 for three more rounds.

-  Note the route-4 Create half is ALREADY DONE (C3b/C3c); the remaining work is

-  4a contract: [`2026-08-03-c4-route-4a-contract.md`](../research/2026-08-03-c4-route-4a-contract.md).
-  **Route 2 connected gate PASSED (user, 2026-08-03).** Provoked with the
-  retail `@pklite` entry-collision bump (`69ba9486` — the only reachable ACE
-  trigger for `ObjectForcePosition`; admin teleports advance `ObjectTeleport`
-  and exercise route 3 instead, see
-  [`2026-08-03-c4-route-2-visual-gate.md`](../research/2026-08-03-c4-route-2-visual-gate.md)).
-  The user observed the visible slide off the overlapped character (the
-  ForcePosition applied), correct animation, no heading change, and no leash
-  tethering or rubber-band after the correction — so the two named behaviour
-  changes (ack after commit; no `ConstrainTo` re-arm on this route) are
-  accepted live. Both Opus reviews PASS on the final diff after three FAIL
-  rounds.
-  **Adjacent, NOT a route 2 regression:** shipping `@pklite` made PK Lite
-  reachable for the first time and immediately exposed pre-existing PvP gaps —
-  melee/ranged attacks refuse a PKLite target (auto-target retargets to the
-  nearest other; auto-target off does nothing) while spells on the same target
-  work. Under investigation; filed separately.
-  **Route 2 (ForcePosition) — implemented 2026-08-03, contract:**
-  [`2026-08-03-c4-route-2-contract.md`](../research/2026-08-03-c4-route-2-contract.md),
-  **plan:** [`2026-08-03-c4-route-2-implementation-plan.md`](../research/2026-08-03-c4-route-2-implementation-plan.md).
-  `RuntimeAcceptedPositionDriveController`
-  (`src/AcDream.Runtime/Session/RuntimeAcceptedPositionDriveController.cs`)
-  is the single accepted-Position execution seam for a ForcePosition on the
-  already-live local player; `LocalForcePositionTransaction` and
-  `HeadlessSessionWorldProjection.BlipLocalPlayer` are deleted, and the
-  generic App render-tail is skipped for the local player's ForcePosition.
-  Named behaviour changes (both retail-exact, ISSUES #285): the outbound
-  ack now fires strictly after the canonical commit, and the constraint
-  leash is no longer re-armed on this route (retail's FORCE_POSITION branch
-  never reaches `ConstrainTo`).
-  **Fix round (2026-08-03):** both independent dual reviews (retail-
-  conformance + architecture/adversarial) FAILed the first pass — see
-  [`2026-08-03-c4-route-2-review-findings.md`](../research/2026-08-03-c4-route-2-review-findings.md)
-  for the full R1-R9 list. The critical finding (R1) was that the
-  DeferredCell park could not survive a single ACE broadcast interval in
-  production (`RuntimeEntityObjectLifetime.TryApplyPosition`'s unconditional
-  `Forget` on every accepted Position cancelled it before its collision
-  generation could commit), silently dropping the correction forever;
-  `RuntimeAcceptedPositionDriveController.Advance` now detects the dead
-  watch and re-issues from the entity's current canonical snapshot. R2/R3
-  restored headless's collision re-centering and login-window fallback; R4
-  stopped the force-ack from stealing a receipt the presentation sink had
-  legitimately declined; R5/R6/R9 corrected false doc claims, closed a
-  `_pending`-leak/overwrite gap, and fixed streaming-observer/pose-dirty
-  side effects firing on a declined placement. R7 corrected a fixture bug
-  (a dummy Setup sphere with its centre at the origin) that had been
-  written up as a retail fidelity gain; R8 added App-layer double-write
-  source pins and corrected an overclaimed single-ack test. Full detail:
-  [`2026-08-03-c4-route-2-review-findings.md`](../research/2026-08-03-c4-route-2-review-findings.md).
-  Complete Release solution after the fix round: **10,853 passed / 4
-  skipped / 0 failed** (baseline 10,844/4/0; first pass 10,848/4/0).
-
-  **Acceptance item 2 is NOT met — recorded gap, B2 (2026-08-03 round 2).**
-  An earlier revision of this paragraph claimed R8 "added the App-layer
-  double-write source pins the plan's own acceptance item required". That was
-  a claim of coverage this changeset does not have, and it is corrected here
-  rather than left as the citation a future session trusts (same rule that
-  produced R7). The truth, per the adversarial review:
-  - *First half — "the generic tail no longer double-writes the local
-    player":* **source-pinned, not proven.** The pin is a regex/`Assert.Single`
-    over `LiveEntityNetworkUpdateController`'s source text, so it would still
-    pass if a second write were spelled differently, and **no test exercises
-    the branch** at runtime.
-  - *Second half — "the committed projection is what moves the render
-    entity":* **uncovered at any layer.** No test drives a route-2
-    ForcePosition through `RuntimePlacementPresentationSink` /
-    `TryApplyRuntimePlacementPlace` and asserts the `WorldEntity` actually
-    moved. Given R4 (the force-ack no longer consumes a declined `Place`),
-    this is precisely the seam whose failure mode is silent: the canonical
-    body moves and the render entity stays put.
-  Closing this gap needs an App-layer test that runs the accepted
-  ForcePosition end to end and asserts the render entity's position/cell came
-  from the committed placement receipt — carry it into C5's parity tests or
-  file it before this sub-landing closes.
-  **Not yet done:** both reviews must be RE-RUN on this fixed diff, and the
-  connected (user-gated) acceptance gate this campaign's standing
-  discipline requires, before this sub-landing is considered closed — those,
-  and the commit itself, are next. May land as more than one commit if a
-  route proves large; each sub-landing keeps the full review discipline.
- **C5 — legacy deletion + closeout gates — OPEN.** Delete every superseded legacy
-  path; parity tests; exact lifecycle/reconnect + canonical nine-stop
-  connected routes; two-client observation; **user visual matrix** (the
-  campaign's stopping point for user acceptance). Retire AP-1, AD-1,
-  AP-131, AD-60's legacy half, and close #275. Update register/roadmap/
-  milestones/architecture/memory + successor handoff.
-  **Inheritance recorded at C4 closeout (2026-08-05, full detail in
-  [`2026-08-05-c4-closeout-handoff.md`](../research/2026-08-05-c4-closeout-handoff.md)):**
-  the #318 end-to-end portal composition test, whose discriminating
-  assertion is that **`PhysicsEngine.ShadowObjects` holds a row at the
-  destination — not just `LocalPlayerShadowState`'s dedup cache** (AP-145's
-  cache-without-publish asymmetry is why a cache-only assertion is satisfied
-  by the bug); the route-3 C5 sweep candidates (`ILocalPlayerTeleportPlacement`
-  as a thin acknowledge seam; the test-only `BeginAcceptedPlacement`/
-  `BeginAuthoredPlacement` wrappers); #276's settle-cell remainder and
-  #277's trigger-conditioned conversion; #316's measure-before-fix, #317's
-  velocity-chain audit, #313, and #309's re-scoped narrow half; the
-  cell-less live-trigger investigation (owed gate 4); and the TEMPORARY
-  physics probe family strip (`REMOTE_LANDING`/`REMOTE_SLIDE`/`PARK`/
-  `REMOTE_TELEPORT`/`CHILD_CELL`/`LOCAL_TELEPORT`) — after, never before,
-  the four owed gates consume them.
-  **#280's connected gate rides this matrix (added 2026-08-05).** Release,
-  `ACDREAM_RETAIL_UI=1`, `ACDREAM_STREAM_RADIUS` **UNSET** (it forces
-  `NearRadius` and only raises `FarRadius`, so a run with it set measures a
-  different window than production). Run the route TWICE on the same binary —
-  once with `ACDREAM_PROBE_REVEAL_RADIUS=1` (reproduces the pre-#280 gate) and
-  once without — and report BOTH. The user-facing observable is an ABSENCE, so
-  the pass criteria are three positive artifacts per stop, all from existing
-  machinery: (1) a `world-visible` checkpoint JSON whose
-  `StreamingWork.NearBacklog` / `.FarBacklog` / `.DestinationBacklog` /
-  `.PendingPublications` are zero for the destination window at the moment the
-  viewport opened; (2) a hold-duration pair — **the post-fix hold is EXPECTED
-  to be LONGER**, and a hold that is not longer means the gate did not widen
-  and the run proves nothing; (3) a paired screenshot per stop, where the
-  pre-fix run is the one that shows the defect. `wait world-visible 30000` in
-  `tools/connected-world-lifecycle.route.txt` is the convergence ceiling — a
-  trip is a failure, a longer pass is not. **The reported repro was a RECALL,
-  not `/teleloc`: the matrix needs a lifestone/recall leg**, and it must
-  include a first-login stop, because login shares the same barrier and its
-  gate widened too.
-
-After C5: ~~AP-22~~ (RETIRED 2026-08-06, bc4679cd) and ~~AD-10~~ (RETIRED
-2026-08-06 by deletion, 886333a2) are both DONE. Historical text follows.
-After C5: AP-22 (authored collision shapes), then AD-10 (remote
-contact-plane projection), then the campaign's final matrix and ledger
-closeout; vendor Slice 5 resumes.

-# Recent-regression cleanup — plan (2026-08-03)
-
-Three defects introduced by the 2026-08-02/03 stabilization batch, found while
-reconciling the #281 test failures. All three are **ours, days old, and inside
-the least-verified code in the tree**. They are cleared before C4 resumes so
-six more placement routes are not stacked on top of them.
-
-Issues: #282 (two cell fields), #283 (two world origins), #284 (silent park).
-
-## Status — CLOSED 2026-08-03
-
-All three landed and are user-accepted.
-
-| Slice | Issue | Commit | Outcome |
-|---|---|---|---|
-| S1 | #284 | `97d11e6c` | Park reasons named; terminal on the contradictory state |
-| S2 | #282 | `3c36b4cc` | One cell owner (`VisibilityCellId`); register row AP-133 |
-| S3 | #283 | `898ff18b` → `89cf1e66` | Measured UNREACHABLE; permanent invariant instead of a restructure |
-
-Connected Release gate (retail UI) on S1+S2: user verdict "works fine"; log
-showed 9 completed reveals, 58 reveal events all `failures=0`, zero unhandled
-exceptions, zero parked placements, graceful exit (`0c14c402`).
-
-S3's probe run recorded zero disagreements across 11 reveals and six landblocks
-spanning ~45 km, so ownership was deliberately left alone — the evidence
-disproved the hypothesis, and the guard exists to keep it disproven.
-
-Final complete Release solution: **10,844 passed / 4 skipped / 0 failed.**
-
-Next: the original campaign order below, starting at C4 route 2.
-
-## Why these first
-
-Every one is an instance of the exact weakness the placement campaign exists to
-remove: **two owners of one fact, with no single writer keeping them agreed.**
-#282 duplicates "which cell is this in". #283 duplicates "where is zero". #284
-is why both stayed invisible. Fixing them inside C4 would mean diagnosing them
-through C4's much larger diff.
-
-## Standing discipline for this plan
-
- Retail is the oracle. Grep `docs/research/named-retail/acclient_2013_pseudo_c.txt`
-  by `class::method` before writing.
- Root causes only. No timeouts, grace periods, suppression flags, or
-  catch-and-ignore. #284 in particular is observability + fail-fast, never a
-  retry cap.
- **The complete Release solution suite must be green before every commit.**
-  Focused-run-only gating is exactly what let #281–#284 ship. The full suite
-  takes about 30 seconds; there is no excuse.
- Each fix is its own bisectable commit with root-cause evidence, and updates
-  the issue + divergence ledgers in that same commit.
-
---
-
-## S1 — #284: make a parked placement visible (do this first)
-
-Smallest, and it turns the other two from archaeology into observation.
-
-1. Classify the park reason at the single site that produces it
-   (`RuntimeSetPositionState.PrepareMover`): awaiting collision generation,
-   awaiting Setup, awaiting world frame.
-2. Fold per-reason parked counts into the existing physics ownership snapshot
-   (`RuntimePhysicsState.CaptureOwnership`) so they appear wherever ledgers are
-   already asserted, and in the connected gates' `report.json`.
-3. Fail fast on unresolvable parks. A park awaiting the world frame *while a
-   local player is already registered* is not a wait — it is a contradiction.
-   Surface it as a committed invariant exception, the pattern `01f4791e`
-   established for receipt-ledger violations.
-4. Convergence contract: parked entries must be zero at every stable
-   checkpoint. Wire that into the lifecycle/nine-stop gate assertions.
-
-**Tests:** each park reason is reported exactly once and clears on resolution;
-the contradictory park throws rather than retrying; ledgers converge to zero.
-**Gate:** focused Runtime + complete solution suite.
-
---
-
-## S2 — #282: one owner for an entity's visibility cell
-
-1. **Establish the retail model.** `CPhysicsObj::set_cell_id` @0x0050f4f0,
-   `change_cell` @0x00513390, `set_cell_id_recursive` @0x00510da0,
-   `ShouldDrawParticles` @0x0050fe60. Retail carries ONE cell per physics
-   object, and particle gating reads that same cell. Write the pseudocode note
-   before touching C#.
-2. **Audit the writers.** 12+ sites write `ParentCellId`
-   (`LiveEntityNetworkUpdateController` ×4, `RemotePhysicsUpdater` ×2,
-   `ProjectileController` ×3, `LiveEntityOrdinaryPhysicsUpdater`,
-   `LocalPlayerProjectionController`, `RemoteTeleportController`, …); 3 write
-   `EffectCellId`, all in `LiveEntityRuntime`. For each `ParentCellId` writer
-   record whether it also rebuckets — a rebucket with an exact cell currently
-   repairs the pair by accident. Produce the table before choosing the fix.
-3. **Decide the shape.** `EffectCellId`'s documented purpose is narrow: outdoor
-   dat stabs that keep a null render parent while retail still gives them an
-   outdoor landcell. Live/interior entities were explicitly meant to use
-   `ParentCellId`. Preferred fix, in retail's direction: live entities stop
-   populating `EffectCellId`, the stab case keeps it as the documented
-   exception, and one owner writes the visibility cell that the effects path
-   reads. If the audit shows live entities genuinely need it, the alternative
-   is a single writer that maintains both — but never 12 independent writers
-   against a field that wins.
-4. **Divergence register.** The two-field split is an adaptation from retail's
-   single cell. Add the row if none exists; delete it if step 3 collapses the
-   split.
-
-**Tests:** an entity crossing a cell boundary keeps its particles and lights
-attached; an equipped/attached child keeps its parent-relative behaviour; the
-outdoor dat stab case is unchanged.
-**Gate:** focused App + complete suite, then a **user visual check** — a
-monster with an active spell effect crossing a cell boundary, and a lit static
-object, indoors and outdoors.
-
---
-
-## S3 — #283: one owner for the world origin
-
-Sequenced last of the three and immediately before C4 route 3, which touches
-the same portal code.
-
-1. **Prove or disprove reachability first.** With S1 landed, assert at the
-   placement site that Runtime's frame center and App's `LiveWorldOriginState`
-   center agree; run the portal/recall routes. If they never diverge in
-   practice, the fix is a permanent invariant rather than a behaviour change —
-   record that and stop. Do not restructure on a hypothesis.
-2. **Retail evidence.** How retail rebases its landblock offsets across a
-   teleport, and the ordering around `TAS_TUNNEL_CONTINUE` — the same
-   sequence #280 already needs read. Read once, use twice.
-3. **Fix shape.** Runtime owns the world frame; App projects it. Today
-   `LiveWorldOriginState` is an independent owner with its own rebase edge.
-   Make it a projection of Runtime's frame, so there is exactly one origin and
-   the retirement-driven edge becomes a *publication* of that origin rather
-   than a second decision. This is the same ownership move the campaign has
-   already applied to entities, physics, and placement.
-4. **Ordering invariant.** No placement may commit against an origin the
-   render side has not adopted. Whether that is expressed as a gate or made
-   structurally impossible falls out of step 3.
-
-**Tests:** a teleport whose old-window retirement lags by many frames cannot
-commit a placement against a mismatched origin; frame and origin rebase
-together; ordinary movement rebases neither (already pinned by
-`RuntimeWorldFrameTests`).
-**Gate:** focused + complete suite, lifecycle/reconnect, and a **user visual
-check** on repeated portal/recall arrivals with objects present.
-
---
-
-## After S1–S3
-
-Resume the original campaign order, unchanged:
-
-1. **C4 routes 2–7** — ForcePosition, portal (with S3 landed), remote
-   Create/Position, projectile correction, drops, pickup/parent/delete.
-   Fold in #276 and #277 where their route becomes authoritative.
-2. **#280** — retail destination prefetch, landed adjacent to route 3.
-3. **C5** — delete superseded writers, complete suite, lifecycle/reconnect,
-   nine-stop soak **on the final binary**, two-client observation, the #269/#278
-   slope-glide check. Only then retire AP-1, AD-1, AP-131, and AD-60's legacy
-   half.
-4. **AP-22** — `ShadowShapeBuilder` as sole authority for authored Setup
-   collision shapes.
-5. **AD-10** — remote contact-plane projection through the real transition
-   sweep.
-6. Final movement/collision matrix; ledger, architecture, roadmap, milestones,
-   memory, `CLAUDE.md`, `AGENTS.md`. Vendor Slice 5 resumes only after that.

-# Campaign S — collision shape & response fidelity
-
-**Opened:** 2026-08-06, immediately after #333/#337 closed (`ea83b043`).
-**Status:** IN FLIGHT — overnight session 2026-08-07 ledger:
-S1A (AP-157) closed by measurement, no code · S1B contract ready, not
-implemented · S2 contract ready, not implemented · S3 CANCELLED (planned on a
-misreading — see its section) · S1B LANDED (b3e43d22, #335 closed) and S2 LANDED (9671af02, AP-155
-narrowed), Session-B dungeon gate USER-PASSED 2026-08-07 evening ("Feels
-good!") · S4 half-landed (AD-65 shipped and USER-PASSED at the 2026-08-07 morning gate; AD-66 withheld
-behind #341's measurement anomaly; AD-69 filed) · S5 closed (fix predated the
-campaign; zombie register row) · S6 LANDED (containment: the camera provably reaches BOTH ACE-derived TOI
-tails live — the rows' dormancy premise was false; guarded with counters +
-one-shot unverified-mover log, four tests, sabotage on the real exemption
-axis; AP-83/AP-91 rewritten CONTAINED-not-dormant, severity camera-feel
-only) · **CAMPAIGN CLOSED 2026-08-07 night** with ONE honestly-open item:
-AD-66's reland is blocked by the #341 codegen-shape measurement instability
-(twice self-refused by its own stability gate; the ABA evidence and the

-## Why a campaign and not twelve tickets
-
-Three of these rows edit the same two functions. `AP-157` and the `AP-156`
-residual both live in `ShadowObjectRegistry.BuildFloodSpheres`; `AP-159`/`#335`
-lives one call away in `CellTransit.BuildShadowCellSetFromParts` and in
-`ShadowObjectRegistry.BuildBspPartSpheres`. Shipping them as separate tickets
-means three review cycles over the same code and three chances to reintroduce
-each other's bugs. This project already has a written rule about exactly that
-shape of work: **shared-file slices are ONE agent against a pinned contract**
-(`feedback_dont_parallelize_coupled_plan_slices`).
-
-The second reason is ordering. **Membership gaps mask query gaps.** We just
-watched it happen: AP-156 put geometry into the right cell and AP-158 threw it
-away one layer down, so AP-156's entire visible benefit was invisible until
-#333 landed. Anything upstream of the query has to be correct before a gate on
-the downstream math means anything.

-## The governing lesson from the last campaign

-**The register rows are leads, not specifications. Measure before you fix.**
-The evidence, all from the last two weeks:
-
- **AP-155(b) recorded the flood approximation as OVER-inclusive**, and used
-  that direction as the reason it was safe to defer. Measured, it was
-  UNDER-inclusive for 428 of 530 Setups — the opposite, and the dangerous
-  direction.
- **AP-156's risk column was wrong**, and its wrongness is precisely why #334
-  — a user-visible loss of collision — sat inside it unnoticed.
- **AP-22 described an unreachable branch.** 0 of 5,935 installed Setups could
-  satisfy its guard. The correct fix was deletion, not a port.
- **#331's headline claim was refuted outright.** The behaviour was already
-  retail-faithful.
-
-So one row in four, in this exact domain, was materially wrong about its own
-population, direction, or existence. **Every slice below opens with a
-measurement that can cancel it.** A slice that measures its population at zero
-closes as "row deleted", and that is a success, not a wasted slice.
-
---
-
-## Slice order
-
-### Pre-work — two cheap unblocks, before the campaign proper
-
-Both are the user's own outstanding reports and both are blocked on a
-measurement that costs far less than the fix. Neither is a campaign slice.
-
-**PW-1 — #338, the step heights.** Setup `0x02000001` authors
-`StepUpHeight = 0.600` / `StepDownHeight = 1.500`; the client resolves with
-`0.400` / `0.400`. **First question is whether retail reads the authored field
-at all** — grep `named-retail` for the step-height getters and their callers.
-If retail substitutes its own constants, 0.4 is correct and #338 closes as a
-non-defect. ~30 minutes. Do not touch code before that answer.
-
-**PW-2 — #32, local-player cliff edge-slide.** This is the *other half of the
-original two-bug report* and the thing the user will feel most, so it does not
-sit behind six slices. Research is already done (`38db9fff`):
-`CollisionInfo.SetContactPlane` latches last-known at all 13 call sites where
-retail's `COLLISIONINFO::set_contact_plane` @0x00509d80 — 22 bytes — never
-does. Fix is ~20–25 lines, mostly deletion, in 2 files. **Blocked on a live
-`ACDREAM_DUMP_EDGE_SLIDE=1` capture**: the report's six-row decision table has
-three rows that redirect the fix entirely. Needs the user at the client.
-
---
-
-### S1 — The flood / membership pipeline
-
-**Rows:** AP-157, AP-156 residual, AP-159 / #335.
-**Files:** `ShadowObjectRegistry.cs` (`BuildFloodSpheres`, `BuildBspPartSpheres`),
-`CellTransit.cs` (`BuildShadowCellSetFromParts` indoor arm),
-`ShadowShapeBuilder.cs`.
-**One agent. Pinned contract. Not parallelised.**
-
-This is the walk-through direction and the largest single win in the list.
-
- **AP-159 / #335** — indoors we admit an EnvCell neighbour on a *sphere* test
-  where retail hands the part array to each cell's own `find_transit_cells` and
-  tests every part's sphere against that cell's portal planes in cell-local
-  space. Port the part-array overload. This is the last of AP-156's traversal
-  residual; the outdoor half already closed with #334.
- **AP-157** — retail's third `calc_cross_cells` branch floods from ONE
-  `CPartArray::GetSortingSphere`; we flood from every Sphere shape. Our
-  cylinder flood also ignores `CylHeight`.
- **AP-156 residual** — we scale the flood sphere by entity/part scale; retail's
-  `CEnvCell::find_transit_cells` reads only `CPhysicsPart::pos` and never
-  `gfxobj_scale`. Note the asymmetry before changing anything: retail's cross-cell
-  walk is itself under-inclusive for scaled parts and ours is not, so "match
-  retail" here means **deliberately adopting a retail bug**. That is a decision
-  to make explicitly with the user, not silently — over-inclusive is safe,
-  under-inclusive is the walk-through direction.
-
-**Opens with:** an installed-DAT sweep giving each row its true population and
-direction, measured against a DAT field that is not the one being fixed (the
-non-circular-oracle rule that caught AP-156's identically-zero assertion).
-
-**Gate:** offline differential over installed DATs, plus one live indoor run —
-a dungeon with tight rooms and a door.
-
---
-
-### S2 — Static publication shape fidelity
-
-**Row:** AP-155. **Files:** `LandblockPhysicsPublisher.cs`,
-`LandblockPhysicsContentBuilder.cs`.
-
-The static-load paths emit an authored Setup Sphere as a height-capped
-Cylinder. Different files from S1, so it is separable — but it must land
-**after** S1, because S1's flood consumes what these paths produce, and
-measuring S2's effect while S1 is in flight would confound both.
-
-**Gate:** shares S1's live indoor run if S1 and S2 land together; otherwise
-offline only, since a shape substitution's population is fully measurable from
-the DATs.
-
---
-
-### S3 — Animated collision pose — CANCELLED 2026-08-07 (the slice was planned on a misreading)
-
-**Row:** AP-84 — which stays exactly as it is.
-
-This plan's original S3 text claimed "a door's collision stays where the shut
-door was." **That scenario cannot occur, and AP-84's own row says why:** an
-open door is ETHEREAL (#150) and bypasses collision entirely, so the only
-pose a door ever collides in IS the registered default pose. The row's risk
-column already carries the honest residual — "an entity whose server-driven
-motion state materially moves a BSP-bearing part while NON-ethereal would
-collide at the stale default pose (no known case)" — with the revisit
-trigger written. The register was right; this plan's summary of it was
-wrong, which is the same reading failure the campaign's own governing
-lesson warns about, committed by the campaign plan itself.
-
-No fix, no gate, no door row in the morning sitting. AP-84 remains an
-active, deliberate approximation.
-
---
-
-### S4 — Push-out math
-
-**Rows:** AD-65 + AD-66. **File:** `TransitionTypes.cs` (`AdjustOffset`) — both
-in the same function, so one slice.
-
- **AD-65** — the `collisionAngle > 0` arm substitutes `result -= N * angle`
-  for retail's `Plane::snap_to_plane`. Recorded effect: downhill XY travel short
-  by cos²θ (25% at 30°, 50% at 45°).
- **AD-66** — the safety push-out substitutes `radius * ContactPlane.Normal.Z`
-  for retail's bare `radius`, in both the trigger comparison and the `zDist`
-  numerator.
-
-**Correction carried in from the closeout:** AD-65 was previously described as
-"a live lead for #269". That framing is **retracted** — #269 closed 2026-07-31
-on the user's own live gate, and AD-65's sign is *opposite* to that symptom.
-AD-65 stands on its own merits. (#269's do-not-retry covers friction and jump
-chains, which are byte-exonerated; `AdjustOffset` is a different function and
-is not covered by it.)
-
-This is feel, not pass-through. It cannot be gated by a test asserting "did I
-fall through" — it needs a movement-feel gate.
-
---
-
-### S5 — The Sledding flatness constant
-
-**Row:** AD-55. **File:** `PhysicsBody.cs` (`calc_friction`).
-
-We compare `GroundNormal.Z > 0.99999536f` (≈0.175° from flat); the raw decomp
-literally computes `__fcos(0.17453292519943295)` = cos(10°) ≈ 0.984808. One of
-the two is a decode artefact. **Resolve by byte-decoding the constant from the
-PDB-paired binary** — there is a documented method for exactly this
-(`reference_pe_byte_decode`), and it has already caught one inverted mapping
-this project inherited from ACE.
-
-Cheap. **Batch its live gate with S4's** — both are movement feel on slopes,
-and asking for two separate slope-feel sessions wastes the only genuinely
-scarce resource in this campaign.
-
---
-
-### S6 — Containment, NOT a fix
-
-**Rows:** AP-83, AP-91.
-
-**These are not portable and should not be listed as fixes.** The PerfectClip
-time-of-impact tails in `CCylSphere::collide_with_point` and
-`CSphere::collide_with_point` are x87 sequences that do not decompile legibly;
-we took them from ACE. There is no retail text to port. Pretending otherwise
-would put a "port it" ticket in the backlog forever.
-
-The honest deliverable is **containment**: prove no production mover sets
-PerfectClip, and add a guard or test that fails loudly if one ever does. Then
-the rows describe a branch we can show is unreachable, which is the same
-resolution AP-22 got.
-
---
-
-### Parallel track — #330, headless live-entity collision
-
-The headless host registers no live-entity collision at all: a bot walks
-through every NPC and every server-spawned object. The graphical client is
-unaffected.
-
-**Genuinely parallel.** Different host, and — unlike everything above — it
-needs **no live gate from the user at all**, because the headless suite can
-assert it directly. It is the one item that can proceed while the user is
-unavailable, which makes it the right thing to pick up whenever a live gate is
-blocking.
-
---
-
-## Gate economics
-
-The user's time at the client is the only scarce resource here. Live gates are
-therefore **batched, not per-slice**:
-
-| Session | Covers | What to do in-world |
-|---|---|---|
-| A | PW-2 capture | drive the cliff edges that misbehave; capture only, no fix yet |
-| B | S1 + S2 | a tight dungeon with a door; walk boundaries, jump, drop a corpse |
-| C | S3 | doors: open, walk through, close, walk into |
-| D | S4 + S5 | slopes: run down, run across, sled, land on inclines |
-
-Four sessions for the whole campaign. Everything else is offline.
-
---
-
-## Definition of done
-
- Each row either **retired** with its evidence, or **rewritten** with a
-  corrected population/direction, or **deleted** as describing something that
-  does not exist. All three are acceptable outcomes.
- No row is closed on a test that re-computes the production expression as its
-  own oracle. Use an independent DAT field or an independent implementation.
- Every discriminating test is **sabotage-verified**: break the production line
-  and watch the test redden, in the same session it is written.
- `docs/ISSUES.md` and the divergence register updated in the **same commit**
-  as the code, per the register's own two binding rules.

-# Morning gate — 2026-08-07 (one sitting)
-
-**Status: COMPLETE 2026-08-07 — G1 user-passed ("Slopes feels good").**
-
-Everything below folds the deferred visual gates into one sitting, ordered so
-travel between sites doubles as #339 reproduction attempts. Launch is
-prepared by the overnight session; **the client is NOT launched until you're
-back** (your instruction).
-
-## 0. Launch (the lead runs this when you say go)
-
-Main checkout, absolute path, probes armed. The first `[step-h]` line in the
-log must print the assembly path under
-`C:\Users\erikn\source\repos\acdream\src\` — that is the wrong-binary guard,
-now part of every capture.
-
-## 1. Closed overnight with nothing owed to your eyes
-
- **#32 local edge-slide** — you passed it at the Rithwic cliff ("Yes works
-  now"). Ledger closed, AD-67 filed for the one kept residual.
- **#338 step heights** — headline refuted by full-capture statistics
-  (111,248 authored-pair resolves vs 358 placeholder ones); no production
-  change, nothing to look at. AD-68 records the benign async-residency
-  placeholder.
- **AP-157 (S1A)** — measured, both halves resolved without a code change:
-  the CylHeight half is retail's own behaviour (byte-verified), and the
-  sorting-sphere half is real vs retail's registration set but PROVEN unable
-  to change any collision outcome (flood and test geometry are the same
-  spheres). Fix deferred to the next bake-schema revision.
- **AD-55 (S5) — closed, and the fix turned out to be a WEEK OLD.** The
-  cos(10°) constant has been live in production since 2026-07-30
-  (`252e8068`); you've been playing on it. Tonight's byte-decode is an
-  independent confirmation. The register row claiming otherwise was a
-  ZOMBIE: an unrelated revert (`a8a7d64b`) resurrected the retired row —
-  and, found by auditing that same revert, had also silently DELETED the
-  then-active AD-56 row. Both corruptions fixed; the class is now a memory
-  rule. No feel gate owed for S5.
-
-## 2. The sitting — ONE row
-
-| # | What | Where / how | Pass looks like |
-|---|---|---|---|
-| G1 | **S4 / AD-65 — downhill slope feel.** The away-from-plane response now
-  snaps to the surface (XY preserved) instead of projecting (XY shrunk by
-  cos²θ — 25% at 30°, 50% at 45°). | Run DOWN a long slope (the Rithwic
-  descent works), then across it diagonally; jump down-slope and land
-  running. | Downhill ground speed feels like retail — no "wading" slowdown
-  on descents; no new stutter or floatiness; landings keep momentum
-  downhill. |
-
-That is the whole sitting: **one slope run, ~3 minutes.** Everything else
-either closed with no gate owed or was deliberately withheld (below).
-
-## 2.5 Withheld / deferred overnight — nothing to test, decisions recorded
-
- **AD-66 (the push-out's bare radius) — WITHHELD, issue #341.** The port is
-  byte-proven twice over, but the landing produced a measurement that
-  contradicted itself (same binaries, opposite outcomes flipping with test
-  assert shape). Parked behind an instrumentation plan rather than guessed
-  at. AD-69 filed alongside: the same block misses retail's seam-frame
-  correction.
- **#330 headless collision — wiring withheld, hoist landed.** Dual review
-  converged on a real dependency the contract missed: headless has no
-  remote-motion tick, so spawn-registered shadows would freeze into phantom
-  obstacles. The issue now carries the full seven-point scope map.
- **S1B (indoor box-admit) and S2 (static sphere emission)** — contracts
-  written and committed, not implemented; next session picks them up
-  directly.
- **S3 — cancelled**: planned on a misreading; open doors are ethereal, so
-  AP-84's approximation is behaviourally equivalent. The register was right.
-
-## 3. Free riders during travel
-
- **#339 portal-space hang** — every portal you take is a reproduction
-  attempt; if you get stuck again, the log captures the readiness flags and
-  the session becomes the diagnosis session. Nothing to do actively.
-
-## 4. Deliberately NOT in this sitting
-
- **C5c's connected-gate batch** (~1 hr: D-1 scenarios, AP-136 six-step park,
-  route-7, two-client, nine-stop soak) — standing debt by your direction;
-  say the word any morning and it becomes its own sitting. The probe family
-  stays in the tree until it runs.
- **AP-156 scale question** — retail does NOT scale cross-cell flood spheres;
-  we do. Matching retail here means adopting a retail bug whose direction is
-  walk-through for shrunk objects. Your call, explicitly, before any code
-  changes: keep our over-inclusive scaling (safe, divergent) or match retail
-  (faithful, under-inclusive for scale<1). One sentence from you settles it.

-# Campaign A — Audio retail-feel parity
-
-**Status: CODE-COMPLETE 2026-08-08 — awaiting the user listening gate.** All six slices landed (see the ledger). Research phase complete;
-six-lane named-retail decode done, all load-bearing claims byte-verified
-against the PDB-paired 2013 binary (BN pseudo-C alone was NOT sufficient —
-see "BN traps" below).
-
-**Goal:** the client sounds like retail. Every divergence between our audio
-runtime and the 2013 EoR client is either fixed to the retail mechanism or
-recorded in the divergence register with a reason.
-
-**Research base (read the lane note before implementing its slice):**
-
-| Lane | Note | Owns |
-|---|---|---|
-| 1 | `docs/research/2026-08-08-audio-retail-soundmanager-core.md` | SoundManager, falloff, pan, voice pool, prefs |
-| 2 | `docs/research/2026-08-08-audio-retail-ambient-runtime.md` | AmbientSound/ConstantSound/IntermitSound runtime |
-| 3 | `docs/research/2026-08-08-audio-retail-ambient-authoring.md` | Region-file authoring chain, dat coverage |

-
-The older `docs/research/deepdives/r05-audio-sound.md` is SUPERSEDED where it
-conflicts with the lane notes (its §5.1 falloff, §6 music, and §7 ambient
-sections are wrong — Ghidra-era `FUN_xxx` reads that the named decomp + byte
-decode overturned). Slice A6 adds the banner.
-
---
-
-## What retail's audio engine actually is (one page)
-
-Retail is a **2D pan+gain engine**, not 3D audio. Every gameplay buffer is
-created with `m_3D = 0`; the DirectSound 3D listener the client sets up is
-dead code. Spatialization is CPU-side per voice at play time:
-
- **Gain** (`SoundManager::GetAttenuation @ 0x00550020`; byte-decoded):
-  `g = dist < 5m ? vol : 25·vol/dist²`, clamped to 1.0, then multiplied by ONE
-  master knob (`effect_sound_volume` or `ambient_sound_volume`) — clamp
-  first, multiply second — then `db = ceil(20·log10 g)` with a hard floor at
-  −50 dB, below which the voice is **not allocated at all**. Audible radius
-  ≈ 94.2 m at vol 1.0.
- **Pan**: `pan_dB = (int)(−15·sin(Δbearing))`, truncating toward zero,
-  saturated at ±15 dB, forced to 0 when `(int)distance < 5`. No front/back,
-  no elevation.
- **Listener** = `SmartBox::viewer` — the **collided third-person camera**
-  Position, refreshed once per rendered frame (`SmartBox::set_viewer` @
-  `0x00452D36`, `SmartBox::update_viewer` @ `0x00453CE0`), falling back to the
-  player's own position when the camera sweep fails. Only its origin and
-  `Frame::get_heading` are read. (An earlier draft of this plan said the
-  listener is the player and called acdream's camera listener a defect —
-  wrong, and corrected at A2. Do not re-"fix" it.)
- **Voice pool**: allocator is `SoundManager::PlaySoundInternal @ 0x0054FEC0`.
-  Eviction compares the DAT-authored **float priority** (0..1); equal
-  priority never evicts. (`FUN_00550AD0` cited in our code is a hash-table
-  constructor — wrong symbol.)
- **No loops, no pitch**: retail never sets the DSound loop flag and never
-  calls `SetFrequency`. "Looping" ambients are re-fired one-shots.
- **Variant selection** (`SoundTableData::Lookup` + play sites): pick
-  `idx = (int)(roll01 · (n−1))` — uniform over all but the LAST entry
-  (a genuine Turbine off-by-one; the last variant is unreachable and a
-  faithful port keeps that) — then a SEPARATE Bernoulli gate
-  `rand()/32767 < probability`, else **silence**. Probability is a gate,
-  not a weight.
- **Volume field** is unbounded gain (dats go up to 10.0); retail clamps
-  only AFTER the distance divide, so >1 volumes extend audible range.
- **Prefs** (`InitPrefs @ 0x005503F0`, 8 keys): three float volumes
-  (effect / ambient / interface — interface is registered but **never
-  read**), three enable bools, `Sound Features` (==1 disables pan),
-  `Play Sound Only When Active`. There is NO music knob.
- **Quirk (faithful-port decision)**: effect and ambient volumes are each
-  applied twice (once at the play site, again inside GetAttenuation) — the
-  sliders are effectively **squared**.
-
-**Sound triggers, exhaustively** (lane 5): (1) animation hooks
-(SoundHook/SoundTableHook/SoundTweakedHook) — footsteps, combat swooshes,
-all authored in MotionTables; (2) the server `Sound` event **0xF750**
-(`guid, SoundType, vol`) — hits, wounds, wield, pickup, locks, lifestone,
-spell resists; retail queues an event for a not-yet-known guid and replays
-it on CreateObject, and plays at the WIRE volume, ignoring the table
-entry's volume (the hook path does the opposite); (3) PhysicsScripts
-(0xF754/5 — already live in acdream); (4) UI sounds via the ClientUISystem
-sound table loaded by `DBObj::GetByEnum(0x22, slot 7)`; (5) region-authored
-ambients (below). `CPhysicsObj::play_sound` has exactly ONE caller — the
-0xF750 handler. There are NO client-local collision/jump/water sound call
-sites; inventing one is a divergence.
-
-**Ambients** (lanes 2+3): authored entirely in `region.dat`
-(`Region.SoundInfo` → `AmbientSTBDesc[]` referenced by scene types ← terrain
-types). On every **objcell change** (24 m), `CellManager::ChangePosition`
-rebuilds weights by walking the **3×3 landblock ring × 64 land cells each**,
-decoding each cell's terrain word to (terrainType, sceneIdx) and
-accumulating per-sound inverse-square weight (1.0 inside 20 m, `(20/d)²` to
-120 m, 0 beyond) plus an 8-way bearing histogram. Playback is a min-heap of
-absolute deadlines ticked from the frame loop; each pop plays a one-shot
-and re-arms. `base_chance == 0` ⇒ **ConstantSound**: non-positional,
-volume = its weight share of total (a real terrain crossfade), re-fires
-every `min_rate` s. Non-zero ⇒ **IntermitSound**: authored fixed volume,
-positioned at a random accumulated bearing ±11.25° at distance
-`min + (max−min)·t²`, gated by `roll ≤ base_chance`, interval
-`RollDice(min_rate, max_rate)`. **Indoors is silent by design** —
-`CEnvCell::add_ambient_sounds` is an empty folded `ret`; EnvCell has no
-sound data. No day/night/weather selection exists.
-
-**Music does not exist** (lane 6): the linked winmm MIDI player has zero
-callers (`midiPlay` = 4 textual occurrences: definition + its own queue
-drainer; verified independently), "music" appears 0 times in the 65 MB
-decomp, no SoundType music member, no music pref, no music files shipped.
-`MediaMachine` is a UI-state media bytecode VM whose `Update_Sound` routes
-LayoutDesc-authored waves/table rows to the interface bus.
-
-### BN traps (binding on every slice — reread before porting)
-
-Binary Ninja renders x87 memory-operand compares as unimplemented `bool p`
-and elides the constants; **five** sites would have ported with inverted
-polarity or zeroed math: `is_continuous`, both `CanHear`s, `PlayNow`,
-`PlayProbability`, plus `GetAttenuation` printing `* 0f`. Byte-decode the
-PDB-paired binary (`reference_pe_byte_decode.md` workflow) for ANY float
-compare or constant in this subsystem. The lane notes contain the verified
-values; if a needed constant is not in a note, decode it — do not trust
-the pseudo-C rendering and do not guess.

-## Where acdream is today
-
-Working and retail-correct-in-shape: the animation-hook trigger path
-(`AudioHookSink`, correctly the only client-local trigger), SoundTable/Wave
-dat parsing (byte-exact vs retail), `SoundId` enum (golden-conformance
-tested), entity→SoundTable resolution (Setup-then-wire precedence),
-world-audio quiescence across portal transitions, AL buffer budget/lifetime.
-
-Divergent or missing, ranked by audible impact:
-
-| # | Defect | Where | Symptom |
-|---|---|---|---|
-| 1 | Probability gate absent: `SoundCookbook.Roll` short-circuits single-entry lists (4,183/4,184 entries!) before any roll; CDF walk instead of `(n−1)` pick + gate | `SoundCookbook.cs` | Idle chatter ~20× too often; nothing ever randomly silent — the "incorrect ambient-ish noise" complaint |
-| 2 | 0xF750 unhandled — zero hits in `src/` | `Core.Net` routing | Every server cue silent (hits, wounds, pickup, locks, lifestone…) |
-| 3 | Falloff: AL `InverseDistanceClamped` ref 2 m ⇒ `2/d` first-power, no −50 dB cutoff; AL's 3D panner instead of retail's ±15 dB angular pan | engine + `WorldRenderFrameBuilder` | Wrong loudness curve in both directions — quieter than retail up close, audible where retail is silent; stereo image wider and 3-D where retail's is a narrow angular pan (AP-28) |
-| 4 | Priority float [0,1] cast to int 0..7 → 4,100 entries collapse to 0; eviction compares gain not priority | `AudioModel`/engine | Eviction ordering gutted under voice pressure |
-| 5 | Volume clamped at field instead of after distance divide | `AudioHookSink` | >1-gain sounds lose up to 3× audible range |
-| 6 | Region ambient system absent (`StartAmbient` stub) | engine | Silent outdoors atmosphere (TS-29 half) |
-| 7 | UI sound bank absent; AdminEnvirons stingers logged not played; portal enter/exit cues missing | — | TS-54, AP-115 |
-| 8 | `PlayMusic`/`StopMusic`/`MusicVolume` model retail code that never runs | `IAudioEngine`, settings | Dead API + misleading settings knob |
-| 9 | Dead code: `AudioFalloff` (wrong constants, unused), wrong `FUN_00550ad0` citation, invented `PitchMin/PitchMax`+`Loop`+`Is3D` fields on `SoundEntry` | `AudioModel.cs`, engine header | Traps for future readers |
-
-Register rows in scope: **AP-28** (retire at A2), **AP-115** sound half
-(retire at A4), **TS-29** (retire at A5/A6), **TS-54** (retire at A4),
-**TS-9** (re-scope at A6 — dat census says exactly 1 of 786 waves is MP3).
-Issue **#321** (sound-cache decode-dedup race) folds into A6.
-
---
-
-## Slices
-
-Ordering is audible-value per effort; A1–A2 are the "it sounds wrong"
-fixes, A3–A4 the "it's silent where retail speaks" fixes, A5 the big new
-system, A6 the cleanup. Each slice: grep-named → (byte-decode if any new
-constant) → pseudocode check against lane note → port → conformance tests →
-build/test green → commit; user listening gates where marked.
-
-### A1 — Selection-model correctness (small; biggest audible fix)
-
-Replace `SoundCookbook.Roll` with retail's exact model: uniform
-`idx = (int)(roll01 · (n−1))` (preserving the last-entry-unreachable
-off-by-one), then the separate Bernoulli probability gate returning
-"silence" — including for single-entry lists. Priority stays float [0,1]
-end-to-end (`SoundEntry.Priority`, engine slots). Volume passes through
-unclamped; clamp moves to post-attenuation (staged here, consumed by A2).
-Delete the invented `PitchMin/PitchMax/Loop/Is3D` fields. Rewrite
-`SoundCookbookTests` against golden values from the lane-4 note's decoded
-tables; add a distribution test for the gate.
-
-Acceptance: conformance tests green; connected sanity — creature idle
-chatter audibly rare (Speak1 ≈ 5% per trigger, was 100%).
-
-### A2 — Falloff/pan/listener/voice parity (retires AP-28)
-
-Port `GetAttenuation` + pan CPU-side exactly (5 m knee, `25·vol/d²`,
-clamp-after, ceil-dB, −50 dB no-allocate floor, `−15·sin(Δheading)` pan
-±15 dB with 5 m dead zone, `Sound Features==1` pan disable). OpenAL
-becomes a dumb 2D voice bank: source-relative sources, per-voice gain +
-pan (AL_POSITION azimuth from pan only); remove AL's distance model and the
-listener orientation math.
-
-**Listener correction (2026-08-08, from the lane-1 decode):** an earlier draft
-of this plan said the listener must move "from camera pose to player
-position/heading" and listed "listener = CAMERA" as a defect. That was wrong,
-and it was written before lane 1 landed. Retail's listener IS the camera:
-`SmartBox::set_viewer` @ `0x00452D36` hands the same COLLIDED third-person
-camera Position to `SoundManager::SetPlayerPosition`, the sky, and the camera
-setup, refreshed once per rendered frame from `SmartBox::update_viewer` @
-`0x00453CE0` (falling back to the player's own position when the sphere sweep
-fails). acdream's chase camera collides too, so the position source was already
-faithful; only the HEADING extraction changes, since retail reads
-`Frame::get_heading` — one compass bearing — and never a forward/up basis.
-Do not "fix" this back.
-
-Eviction compares float priority (equal never
-evicts); fix the pool citation to `PlaySoundInternal @ 0x0054FEC0`.
-Keep the squared-volume quirk faithful (register row if we later soften
-it). Map settings: Master (ours, AL listener gain) + Effect + Ambient +
-Interface mirroring retail's knobs; note interface is read by no retail
-path (we wire it to the UI bus anyway — divergence row, deliberate).
-
-Acceptance: unit tests on gain/pan tables (golden distances from lane 1
-note); **user listening gate** — side-by-side with retail: walk away from
-a blacksmith's hammering, confirm matching fade-out distance (~94 m) and
-pan behavior.
-
-### A3 — Server sound path (0xF750)
-
-Parse `Sound` (guid, SoundType u32, volume f32) in the message router;
-route to a new `ServerSoundController`: resolve guid → entity; unknown
-guid ⇒ queue the event and replay on CreateObject (retail
-`CObjectMaint` behavior); known guid without SoundTable ⇒ silent drop;
-play via the SoundTable at the **wire volume** (ignore table volume —
-asymmetric with the hook path, byte-verified). Position at the entity's
-current origin.
-
-Acceptance: wire-format conformance test (three-oracle layout);
-connected gate — melee hits, item pickup/drop, lifestone bind audibly
-fire against ACE.
-
-### A4 — UI + interface sounds (retires TS-54, AP-115's sound half)
-
-Load the ClientUISystem sound table (`GetByEnum` cache 0x22, enum slot 7 —
-resolve the actual DID at port time from `ClientUISystem::GetUISoundTable`).
-Route `PlayUi(SoundId)` through it (delete the no-op). Wire:
-AdminEnvirons 0x65..0x7C → `PlaySoundFromCenter` stingers
-(`WorldEnvironmentController.ApplyAdminEnvirons` already parses them);
-portal enter/exit `UI_EnterPortal`/`UI_ExitPortal`; button/panel cues where
-the retained UI already has command seams; `MediaDescSound` support in
-`LayoutImporter` (DatReaderWriter parses it; interface bus, per lane 6).
-
-Acceptance: connected gate — `@environs` thunder/drums audible; portal
-enter/exit cues audible on recall; **user listening gate** vs retail.
-
-### A5 — Region ambient system (retires TS-29's ambient half)
-
-New `AmbientSoundSystem` (App layer, owned like other world controllers):
-rebuild on objcell change (reuse streaming's cell-transit signal), walk
-the 3×3 ring × 64 cells via the SAME terrain-word decode the scenery
-pipeline uses (`SceneryGenerator`-shared helper), accumulate weight
-(1.0 ≤ 20 m, `(20/d)²` ≤ 120 m) + 8-way bearing, build
-Constant/Intermit instances from `AmbientSTBDesc` (`base_chance == 0` ⇒
-constant — the byte-verified polarity), min-heap of absolute deadlines
-ticked per frame, one-shots through the ambient volume path (squared,
-faithful). ConstantSound non-positional; IntermitSound positioned at
-random accumulated bearing, `min + (max−min)·t²` distance. Teardown on
-world transition via the existing quiescence edge. Indoors: NO ambients
-(retail-faithful); `seen_outside` cells get the outdoor set. Delete
-`StartAmbient`/`StopAmbient` from `IAudioEngine` (wrong shape — looping
-handle API models a mechanism retail doesn't have).
-
-Acceptance: unit tests on weight accumulation + scheduler with a synthetic
-region; **user listening gate** — Holtburg outdoors vs retail side-by-side
-(birdsong/wind character and rough cadence), dungeon silence, ambient
-crossfade walking shore → grass.
-
-### A6 — Deletions, bookkeeping, and the long tail
-
- Delete `PlayMusic`/`StopMusic`/`MusicVolume` and the `AudioSettings.Music`
-  knob (settings migration: drop the field, tolerate old json). Retail has
-  no music system; register row NOT needed once the API is gone (nothing
-  diverges — absence matches retail).
- Delete dead `AudioFalloff` (superseded by A2's ported math).
- r05 doc: SUPERSEDED banner pointing at the six lane notes; corrections
-  list from lane notes §12/§13.
- TS-9 re-scope: 1 MP3 wave in the shipped dats (`0x0A000393`, ~2 s) —
-  either a ~50-line managed MP3 decode for one asset or an accepted-loss
-  row with the census cited. ADPCM count to be measured the same way
-  before deciding.
- #321: make `DatSoundCache` decode-dedup safe under concurrent access
-  (single-flight per wave id) — the full-suite flake.
- Register sweep: retire AP-28/TS-29/TS-54 rows in their landing slices'
-  commits (rule 1); add rows for: interface-volume wired (A2), any
-  softened quirk, and anything discovered mid-campaign.
-
-Acceptance: build/test green, register diff reviewed, no orphaned
-API/settings references.
-
---
-
-## Out of scope (explicitly)
-
- Client-local physics sounds (collision/jump/water) — retail has none;
-  the server sends them. Do not invent.
- Indoor ambient beds — retail is silent indoors.
- A music system — retail has none. (If we ever WANT music, that's a
-  new-feature decision for the user, not parity work.)
- HRTF/doppler/reverb — no retail counterpart.
-
-## Rollback
-
-Each slice is one commit (A6 possibly two); rollback is `git revert
-<slice-sha>`, recorded in this doc's ledger as slices land. A2 and A5 are
-the only slices touching frame-loop code paths; both are behind the
-existing audio-availability guard, so `ACDREAM_NO_AUDIO=1` remains the
-global kill switch.
-
-## Ledger
-
-| Slice | Status | Commit | Gates |
-|---|---|---|---|
-| A1 | **COMPLETE** 2026-08-08 | `c69b3bde` | 42 Core audio tests; full Release suite 11,563 passed / 4 skipped / 0 failed. Closes #355. |
-| A2 | **COMPLETE** 2026-08-08 | `e42b9948` | 118 Core audio tests (mixer + voice pool + cookbook); full Release suite 11,639 passed / 4 skipped / 0 failed. Opus review run and applied — 2 HIGH (pan-law saturation, stale `FUN_00550ad0` header), 5 MEDIUM (untested clamp order / pan truncation / voice pool, dead `PlayingGain`, duplicated heading helper), 5 LOW. Retires AP-28; files AP-173, AP-174, TS-64, TS-65. **Owed: user listening gate.** |
-| A3 | **COMPLETE** 2026-08-08 | `8bc458fb` | 14 wire-conformance tests + 5 controller tests; full Release suite 11,658 passed / 4 skipped / 0 failed. **Owed: connected gate** (melee hit / pickup / lifestone audible against ACE). |
-| A4 | **COMPLETE** 2026-08-08 | `6eaa490b` | UI bank DID resolved from the dats (`0x2000004B`, content-verified: exactly the 32 `UI_*` slots) + 21-case environ table, 30 new Core tests; full Release suite 11,691 passed / 4 skipped. Retires TS-54; narrows AP-115 to notice-only. **Owed: connected gate** (`@environs` thunder + recall cues audible). **Suite note:** two load-dependent measurement flakes were observed on separate full-suite runs (`RuntimeCollisionReportingStateTests.WarmedSteadyContactRefreshDoesNotAllocate`, and one unnamed Core.Net test); both pass in isolation and neither touches audio. |
-| A5 | **COMPLETE** 2026-08-08 | `7c4dd1ad` | 46 ambient conformance tests; full Release suite 11,739 passed / 4 skipped. Opus review run and applied — it caught a FATAL frame bug (cell offsets built in absolute world coordinates while the listener is in the streamed frame: every contribution culled at ~32 km, feature silent with no error), a per-entry vs per-cell denominator error that would have pushed multi-entry beds under the audibility floor, an infinite loop on a zero play-rate, and newly-audible ambients not firing until a full period later. Also moved beds onto retail's single 16-voice priority pool and made the in-block direction test XY-only. Retires TS-29; files TS-66 (`seen_outside` interiors), TS-67 (in-plane weight). **Owed: user listening gate.** |
-| A6 | **COMPLETE** 2026-08-08 | `dd2cb92b` | Full Release suite 11,739 passed / 4 skipped. Deleted the music API (`PlayMusic`/`StopMusic`/`MusicVolume` + the `AudioSettings.Music` knob); exposed the Ambient slider now that A5 drives it; reset the invented 0.8 ambient default to retail's 1.0; SUPERSEDED banner on `r05-audio-sound.md` listing its five wrong sections; TS-9 re-scoped to the measured one-wave blast radius. **Deferred:** #321's decode-dedup race (a pre-existing concurrency flake, not audio-parity behaviour — not fixed speculatively without reproducing it). |

-## CAMPAIGN CLOSEOUT (code-complete 2026-08-08)
-
-Six slices, six commits, `c69b3bde` → A6. The full Release suite ends at
-**11,739 passed / 4 skipped / 0 failed**, up from 11,563 at campaign start;
-the audio subsystem went from 42 tests (one of which pinned the wrong model)
-to ~215 conformance tests written against byte-decoded values.
-
-**What was wrong, and is now right:**
-
-| Was | Now |
-|---|---|
-| Probability treated as a selection weight, and skipped entirely for the 4,183/4,184 single-entry sounds | Retail's uniform `(n−1)` pick plus an independent Bernoulli silence gate |
-| OpenAL 3-D spatialization, `2/d` falloff, no cutoff | Retail's CPU 2-D model: `25·vol/d²` past a 5 m knee, −50 dB no-allocate floor (~94 m), ±15 dB sine pan with a 5 m dead zone |
-| Voices evicted by gain | Evicted by DAT-authored float priority, strictly-less, ring order |
-| `0xF750` unparsed — every server cue silent | Parsed, guid-queued-and-replayed, played at the wire volume |
-| No interface sound bank | Bank DID resolved from the dats' EnumIDMap chain; portal cues + 21 AdminEnvirons stingers live |
-| No ambient system at all | Region-authored, per-land-cell, 3×3 ring, deadline-queue one-shots with terrain crossfade |
-| A music API | Deleted — retail has no music system |
-
-**Process notes worth carrying forward:**
-
-1. **Binary Ninja could not be trusted anywhere in this subsystem.** Five
-   float compares render inverted or with elided constants; `GetAttenuation`
-   prints `* 0f`, which ports as silence at every distance. Every load-bearing
-   value here came from byte-decoding the PDB-paired binary. The lane notes
-   record the verified values; a future reader should decode rather than
-   re-read the pseudo-C.
-2. **Two research notes were wrong and were corrected in place** — lane 1's
-   30 m decibel row (contradicted its own gain column) and lane 5's
-   transposed `GetByEnum` arguments (which would have made the UI bank
-   unresolvable). Both were caught by recomputing rather than copying.
-3. **The reviews earned their cost.** A2's review caught a pan mapping that
-   saturated to full separation where retail gives 15 dB. A5's caught a
-   coordinate-frame error that would have made the entire ambient system
-   silent with nothing logged — the tests passed, the build was green, and it
-   would have failed only at the listening gate.
-4. **An architecture guard caught a design error the tests could not**:
-   `ExtractedUpdateOwners_DoNotRetainAnonymousCallbacks` rejected an
-   `Action<float>` frame hook and forced the typed `IAmbientFramePhase`.
-
-**A4 correction (2026-08-08, from a user question):** the enter cue was hung on the
-`EnterTunnel` event — the first tunnel-family frame — instead of the sequencer's
-`PlayEnterSound`, which is `Begin()` and is what retail's
-`BeginTeleportAnimation` @ `0x004D638E` plays. That delayed it by a whole
-TunnelFadeIn. Both cues now fire on the sequencer's own dedicated sound events
-(`PlayEnterSound` had been emitted and dropped by every consumer since R6), and
-`PortalCues_FireOnTheSequencersOwnSoundEvents_NotOnTheTunnelVisuals` pins the
-moments. The exit cue was already correct.
-
-**Listening-gate round 2 (2026-08-08, inn-chatter finding):** interior
-soundscapes (inn talk-and-laughter) are NOT dat-authored — proven by three
-installed-dat scans pinned in `EnvCellSoundEmitterInventoryTests`: no interior
-static carries an ambient-slot table, no Setup in the whole portal dat
-references one, yet 23 ambient-only soundscape banks exist. They are
-WIRE-BOUND: the server attaches them to emitter objects and fires the slots
-over 0xF750 (ACE: `EmoteType.Sound` heartbeat emotes). Our A3 path is the
-receiver and is live; a probed session (`ACDREAM_PROBE_SOUND_WIRE=1`)
-received ZERO 0xF750 events across a town walkabout, so the silence is ACE
-world-content, not a client drop. Also added this round: `Ctrl+M` instant
-mute (`AcdreamToggleAudioMute` → AL listener gain, unused since A2 — silences
-playing voices immediately without touching the retail mixing math or any
-persisted setting).
-
-**Still owed:** the user listening gate (A2 falloff, A4 cues, A5 ambients) and
-the connected gates for A3/A4. Open rows: AP-173, AP-174, TS-64, TS-65, TS-66,
-TS-67, TS-9 (re-scoped), #321.

-# Campaign OP — retail four-tab Options panel
-
-> **For agentic workers:** slices are executed by ONE Sonnet implementer at a
-> time against this contract, then dual-lens Opus-reviewed, per the binding
-> process rules in §8. The four research docs in §1 are the spec's data
-> appendix — implementers MUST read the cited sections before coding; every
-> table this plan references by section number is committed there in full.
-
-**Status: CODE-COMPLETE 2026-08-11, PARKED 2026-08-11 (user direction) —
-all nine slices landed and reviewed; OP1/OP2/OP7/OP9 CLOSED; OP3–OP6 + OP8
-owe their connected user gates.** Four connected gate rounds ran before
-parking; every finding was root-caused and fixed same-day: #372
-(blank tabs + click diagnostics), #374 (dropdown pointer routing; #376
-split out), #375 (keyboard string resolver + parked prototypes + tab
-activation), #371 (viewport clip), the AD-78 store-only dimming
-(user-directed), and the gate-4 batch #378–#382 (dropdown chrome, chat-only
-opacity scope, slider captions from DAT catalog 0x78000000, the AP-205
-footer field, the AP-206 state-cascade fix). **Resume point: the gate-4
-fixes (`c1218426`..`d1c60df9`) are committed and probe-verified but have
-NOT been seen by human eyes — the user's re-check of those five plus the
-full §OP3–§OP6/§OP8 script is the remaining work. Launch with
-`ACDREAM_RETAIL_UI=1`.** Gate script:
-`docs/research/2026-08-11-campaign-op-test-script.md`. Open tail: #373,
-#376, #377 (fullscreen startup crash — settings.json workaround noted in
-the issue), AP-198/199/202/203/205/206, the Shift-chord display cosmetics
-and the radar-text-over-panel z-order noted in session.**
-
-**Goal:** retail's four-tab in-game Options panel (Gameplay Options /
-Character / Chat / Config), retail-faithful mechanics end-to-end: authored
-LayoutDescs, the real option storage/wire split (`0x0005` single-option vs
-the batched `0x01A1` PlayerModule blob), retail Apply/Reset/Defaults
-semantics, live consumers where acdream has the subsystem and honest
-store-only + register rows where it doesn't, plus the headless-bot
-`characterOptions` seam. Campaign handoff:
-`docs/research/2026-08-10-settings-track-handoff.md`.
-
-**Architecture:** the panel is retained retail UI exactly like Campaign CH's
-chat windows — LayoutDesc `0x2100002B` imported through `LayoutImporter`,
-mounted in the `gmFloatyPanelUI` host `0x2100006E` under
-`RetailWindowManager`, driven by a focused controller. All option
-storage/policy is Runtime-owned (`RuntimeCharacterOptionsState` widened to
-the full retail table); the graphical panel and the headless host are both
-consumers of the one generation-gated `IRuntimeCharacterCommands` seam
-(CH3's precedent). Wire builders live in `AcDream.Core.Net` beside the
-existing `0x0005` codec.
-
-**Tech stack:** existing retained UI stack (`DatWidgetFactory`,
-`LayoutImporter`, `UiRoot`, `RetailWindowManager`), `AcDream.Runtime`
-gameplay owners, `AcDream.Core.Net` message builders, `DatCollection` for
-DAT reads. No new dependencies.

-
-## 1. Research base (committed; the spec's data appendix)
-
-| Doc | What it pins |
-|---|---|
-| `docs/research/2026-08-10-options-panel-structure.md` (lane A) | Layout `0x2100002B` structural inventory (§10.1), tab table property `0x2E`, row-template mechanism (ListBox `P0x64` + `AddItemFromTemplateList`), Apply/Reset/Defaults + visibility semantics (§6, §10.4), Chat tab's 13 checkbox masks + defaults (§8), Config tab's 27 rows + `UserPreferences.ini` keys (§9), open path (F11 action `0x1000001A`, toolbar button `0x1000019B`) |
-| `docs/research/2026-08-10-character-options-map.md` (lane B) | The 50-row / 6-group Character-tab inventory with per-row storage bit, wire route, ACE handling, acdream consumer state (§2–§5); implement-vs-store split (§7.1); bot tiers (§5.2) |
-| `docs/research/2026-08-10-set-character-options-wire.md` (lane C) | The `0x01A1` body = `PlayerModule::Pack` field order (§2.3–§2.7), header invariant `0x460`, the 21-id auto-save table (§3.2), 480 s timer + logout + Apply flush triggers (§3.3–§3.5), ACE acceptance/landmines (§5), CH3 builder post-mortem (§6) |
-| `docs/research/2026-08-10-keyboard-config-and-gameplay-tab.md` (lane D) | The seven Gameplay-tab button behaviours with byte-verified strings (§1–§4), `gmKeyboardUI` structure + DAT ActionMap storage (§5–§6), per-button implementability (§7.1), Config-tab ordered dump (§7.3) |
-
-Coordinator-verified during planning (this session): toolbar button
-`0x1000019B` authors `P0x12 = 0x1000001A` (committed fixture);
-`retail-default.keymap.txt:148` binds `ToggleOptionsPanel` to `DIK_F11`;
-`PlayerModulePackHeader` verbatim at `acclient.h:7835`; the headless
-local-write gap at `src/AcDream.Runtime/Session/DirectGameRuntimeCommandAdapter.cs`
-(`SetSingleOption`) vs `src/AcDream.App/Net/LiveSessionRuntimeFactory.cs:347`;
-**U1 closed**: `UIOption::InqDefaultGameplayOptionProperty @0x004ef8d0`
-resolves per-option defaults from the DAT `DBPropertyCollection` at
-`DBCache::GetDIDFromEnumStatic(0x16, 2)` — the Defaults button restores
-DAT-authored values.
-
-## 2. Design decisions (stated, per the campaign directive; reactable at gates)
-
- **D1 — the retail Options panel is acdream's one in-client settings
-  surface.** Lane D established the F11 `SettingsPanel` was never rendered
-  post-V11 (`ToggleSettingsPanel()` no-op; only `IPanelRenderer` is a test
-  fake). Retail's own F11 IS `ToggleOptionsPanel`. So: F11 + the toolbar
-  button open THIS panel; acdream's client-only settings live on the
-  **Config tab** (retail's own client-settings tab — its 27 rows are
-  `UserPreferences.ini` preferences, nothing on the wire), backed by
-  acdream's existing settings store. The old `SettingsPanel`/`SettingsVM`
-  IPanel surface is retired in OP9; its tested keybind model feeds OP8.
- **D2 — retail's wire split ships exactly.** The 21 auto-save ids send
-  `0x0005` immediately; the rest dirty the module and ride the real
-  `0x01A1` blob with retail's three flush triggers (Apply, logout, 480 s
-  timer). No "send everything as 0x0005" shortcut (lane C: the split is
-  load-bearing in both directions).
- **D3 — the 50th Character row ships.** "Listen to PK death messages" is
-  2015-client; the DAT string exists (`0x0D16E9A3`), ACE maps id `0x34` ↔
-  `CharacterOptions2 0x02000000` but never reads it. Ship the row
-  (user-gate axiom: the user's retail memory includes it), wire+store only,
-  register row for the ACE-sourced 2013-unverifiable mapping.
- **D4 — Configure Keyboard is the campaign's rebind screen** (it is the
-  ONLY rebind screen — D1). Port `gmKeyboardUI`'s shape and DAT ActionMap
-  data (lane D Option C) but persist to `keybinds.json`; retail `.keymap`
-  file interchange is a register-row deferral.
- **D5 — dead-endpoint buttons short-circuit to their own retail failure
-  strings.** Urgent Assistance / Report Abuse open a defunct
-  `support.turbine.com` URL in retail; acdream skips the browser launch and
-  emits the button's own byte-verified failure notice through the
-  interface-text seam (retail text, not invented), register rows filed.
-  In-Game Help mirrors retail-with-missing-`ACHelpPlugin.dll` behaviour.
- **D6 — Exit to Character Selection behaves as Exit Game** (+ register
-  row) until a pre-world character-select flow exists, but retail's
-  confirmation dialog (`ID_Client_EndCharacterSessionConfirm`) and mid-air
-  refusal ("Cannot log off while in mid-air.", byte-verified) ship now.
- **D7 — Group C re-points to server truth.** The seven currently-live
-  `settings.json`-backed options (lane B §7.1 group C) become
-  server-bit-authoritative per CH3 precedent (reseed from
-  PlayerDescription; local-write-then-send). `GameplaySettings`' 16
-  server-shadowing booleans die in OP9.
- **D8 — bots declare options by NAME.** The K1 strict config gains an
-  optional `characterOptions` block accepting exactly the lane-B tier-1+2
-  names; unknown names fail load (ACE throws on unknown ids — never let one
-  reach the wire). Diff-then-send after PlayerDescription seeds state;
-  idempotent on reconnect.
-
-## 3. Slice map
-
-Dependencies: OP1 → (OP4, OP7); OP2 → (OP3, OP4, OP5, OP6, OP8); OP3 → OP4/5/6
-(the shell hosts the tabs). OP7 needs only OP1. Execution order below is the
-default; OP7 may run any time after OP1 when the tree is free.
-
-| Slice | Contract (summary) | Gate |
-|---|---|---|
-| OP1 | Runtime option map + dirty model + the real `0x01A1` builder + headless local-write fix | automated only |
-| OP2 | Type 8 tab control + Type 5 template-list ListBox + remaining `UIOption_*` widget mappings + fixtures | automated only |
-| OP3 | Panel shell + open paths + Gameplay tab end-to-end | user (connected) |
-| OP4 | Character tab: 50 rows, consumers, Apply/Reset/Defaults | user (connected) |
-| OP5 | Chat tab: opacity sliders + 5 per-window filter blocks | user (connected) |
-| OP6 | Config tab: 27 rows over the client settings store | user (connected) |
-| OP7 | Headless `characterOptions` block | automated + bot-vs-ACE run |
-| OP8 | Configure Keyboard screen | user (connected) |
-| OP9 | Closeout: retire dead surfaces, bookkeeping, test script | user (final matrix) |
-

-
-## 4. Slice contracts
-
-### OP1 — the Runtime option map, dirty model, and the real blob
-
-**Files.**
- Modify `src/AcDream.Runtime/Gameplay/RuntimeCharacterState.cs`
-  (`RuntimeCharacterOptionsState`, `:628`): widen to the full table.
- Create `src/AcDream.Runtime/Gameplay/CharacterOptionTable.cs`: the ONE
-  typed table `PlayerOption id → (word: Options1|Options2, mask, isAutoSave,
-  clientDefault)` for ids `0x00..0x34`, transcribed from lane B §2 (verbatim
-  `acclient.h:4162` enum names) + lane C §3.2 (auto-save column) + D3's
-  `0x34` row. Reject `0x35`/`0x36` and unknown ids at the seam (lane C
-  §5.4.3 — ACE throws).
- Modify `src/AcDream.Runtime/GameRuntimeCommands.cs`: add
-  `IRuntimeCharacterCommands.SaveOptions(RuntimeGenerationToken)` (the
-  blob-flush verb) beside `SetSingleOption`.
- Modify `src/AcDream.Runtime/Session/DirectGameRuntimeCommandAdapter.cs`
-  and `src/AcDream.App/Runtime/CurrentGameRuntimeCommandAdapter.cs` +
-  `src/AcDream.App/Net/LiveSessionRuntimeFactory.cs:335-350`: move
-  local-write-then-send INTO the shared Runtime seam so BOTH hosts get
-  retail's ordering (fixes the headless gap lanes B+C independently found).
-  The `LiveSessionRuntimeFactory` local closure is deleted, not duplicated.
- Create `src/AcDream.Core.Net/Messages/SocialActions.cs` addition:
-  `BuildSetCharacterOptions(...)` per lane C §2.7 EXACTLY — header always
-  `0x460` OR-ed with present optional sections; four unconditional u32s
-  (header, options1, spellbookFilters, options2 in pack order §2.3); echo
-  last-parsed shortcuts / 8 spell lists / desired comps rather than zeroing
-  (§5.3); NEVER set `0x100` (lane C U2); omit `0x200` while acdream packs
-  nothing (safe per §2.5); 4-byte tail pad.
- Modify `src/AcDream.Core.Net/WorldSession.cs`: `SendSetCharacterOptions`.
- Dirty model in `RuntimeCharacterOptionsState`: `MarkDirty` on any
-  non-auto-save change, `FirstDirtiedAt`, flush triggers = explicit
-  `SaveOptions` command, session logout, and the 480 s timer (retail
-  constant, lane C §3.3) driven from the existing Runtime tick.
- Tests: `tests/AcDream.Runtime.Tests/` (table completeness ×53, auto-save
-  split ×53 vs lane B §2's byte-verified column, local-write-then-send on
-  BOTH adapter paths, dirty/flush state machine, unknown-id rejection);
-  `tests/AcDream.Core.Net.Tests/` blob conformance: golden byte vector +
-  round-trip through `PlayerDescriptionParser` (lane C §9 S-c — the CH3
-  builder died of green tests pinning a wrong shape; the golden vector is
-  non-negotiable).
-
-**Register rows (same commit):** `0x34` mapping ACE-sourced (D3); the
-480 s autosave if any part is deferred (target: not deferred);
-`GetDefaultOptionValue @0x005D2A30` vs ctor-default disagreement recorded
-when the client-default column lands (lane C §8.2 — reproduce, don't fix).
-
-**Acceptance:** build + FULL Release suite green; blob golden vector
-byte-exact; both adapters share one code path for the local write.
-
-### OP2 — the two widget primitives + remaining UIOption mappings
-
-**Files.**
- Modify `src/AcDream.App/UI/Layout/LayoutImporter.cs` +
-  `src/AcDream.App/UI/Layout/ElementReader.cs`: read tab-table property
-  `0x2E` (struct array `{0x30 button, 0x31 page, 0x32 isDefault}`) and
-  ListBox template-list property `0x64` (entries `{0x63 layout DID,
-  0x62 element id}`) into `ElementInfo`.
- Create `src/AcDream.App/UI/UiTabPanel.cs` (element Type 8 — retail
-  `UIElement_Panel`; renamed from this plan's original `UiTabControl` at the
-  OP2 rework, and a dormant `UiDatElement` subclass per AD-73): tab-button
-  ↔ page-slot switching per lane A §5; default tab honoured.
- Create `src/AcDream.App/UI/UiTemplateListBox.cs` (element Type 5 with
-  authored template list): `AddItemFromTemplateList(index)` instantiates a
-  row from the authored template layout/element via `DatWidgetFactory`,
-  scrollbar named by `P0x72`.
- Modify `src/AcDream.App/UI/Layout/DatWidgetFactory.cs`: map Types 5/8 and
-  `UIOption_Slider 0x10000037`, `UIOption_Menu 0x10000038`,
-  `UIOption_CheckboxSlider 0x10000036`, `UIOption_CheckboxBitfield64
-  0x10000044` (LED checkbox `0x10000035` already maps to `BuildCheckbox`).
- Modify `tests/AcDream.App.Tests/UI/Layout/RetailLayoutFixtureGenerator.cs`
-  (`Layouts`, `:17`): add `0x2100002B`, `0x2100002A`, `0x21000028`,
-  `0x2100005C`, `0x21000029`. **Coordinator runs the generator**
-  (`ACDREAM_REGENERATE_UI_FIXTURES=1`, serial tree) and commits fixtures.
- Conformance tests pin: the tab table (4 entries, Gameplay default), all
-  three template arrays (lane A §10.1), the Character ListBox's 6-header /
-  49-toggle authored row build, scrollbar linkage.
-
-**Acceptance:** build + FULL suite; fixtures committed and pinned; no
-change to any existing widget's behaviour (the S2/AP-192 outline seams from
-`aa6635ae` must be preserved in new widget builds).
-
-### OP3 — panel shell + open paths + Gameplay tab (first vertical)
-
-**Files.**
- Create `src/AcDream.App/UI/Layout/OptionsPanelController.cs`: mounts
-  `0x2100002B` in host `0x2100006E` slot `0x1000018D` (stack key 10) via
-  `RetailWindowManager`; tab control wiring; close button fires
-  `0x1000001A`.
- Create `src/AcDream.App/UI/Layout/OptionPageModel.cs`: the
-  `OptionPage`/`PlayerOptionPage` model — per-page option array of
-  `(current, saved, default)` triples + verbs Apply/Reset/Defaults with
-  retail's exact semantics (lane A §10.4): LED click applies immediately
-  (`SetCurrentValue → Apply(1)`); Apply commits baseline + `SaveOptions`
-  flush; Reset reverts to baseline; Defaults applies live without
-  committing and is never disabled; Apply/Reset disable when clean; hide →
-  revert uncommitted; show → apply + commit. Pure logic, unit-tested
-  without DAT.
- Input action `ToggleOptionsPanel` (`0x1000001A`, F11) in
-  `src/AcDream.UI.Abstractions/Input/` (`KeyBindings.RetailDefaults()` —
-  the ONLY production table; #358's lesson) +
-  `src/AcDream.App/Input/GameplayInputCommandController.cs` routing +
-  toolbar button `0x1000019B` (already authors `P0x12`).
- Gameplay tab (`0x2100002A`, class `gmGameplayOptionsUI`), seven buttons
-  per D5/D6 and lane D §1: Exit Game → the existing graceful-close path;
-  Exit to Char Selection → retail confirm dialog (`RetailDialogFactory`) +
-  mid-air refusal via the interface-text seam, then D6's Exit-Game
-  behaviour; Configure Keyboard → opens OP8's screen; until OP8 lands the
-  button is INERT (authored, clickable, no handler — no invented text, no
-  stub screen), the OP3 gate script says so explicitly, and OP8's gate
-  re-tests it (the campaign cannot close with the button inert); Use Mouse Turning Settings → the six-option macro
-  (lane D §4.4) with its six retail chat lines, camera-mode consumer
-  verified against the camera digest in-slice (register row if the mode is
-  absent); In-Game Help / Urgent Assistance / Report Abuse per D5.
-
-**Register rows:** Exit-to-char-select adaptation (D6); UA/RA dead-URL
-short-circuit (D5); help-plugin behaviour (D5); mouse-turning consumer row
-if needed.
-
-**Gate:** connected — panel opens via F11 AND toolbar; tabs switch with
-Gameplay default; the seven buttons behave per contract; window drags /
-resizes / stacks like the CH6 floaties.
-
-### OP4 — the Character tab
-
-**Files.**
- Create `src/AcDream.App/UI/Layout/CharacterOptionsPageController.cs`:
-  binds layout `0x21000028` root `0x100001F9` ListBox `0x100001FA` through
-  OP2's template mechanism; 6 headers + 50 toggles (D3) in lane B §2's
-  authored order; every row bound by `PlayerOption` id through OP1's table
-  and the shared seam (auto-save ids → `0x0005` on click-apply; batched ids
-  → dirty + blob per OP1).
- Defaults: extract the DAT `DBPropertyCollection`
-  (`GetDIDFromEnumStatic(0x16, 2)`, §1 U1-closure) via `DatCollection` at
-  import; conformance-pin extracted values; cross-check overlapping ids
-  against lane B/C's byte-verified default words and RECORD any
-  disagreement as a finding (never silently pick).
- Consumers (lane B §7.1): group B one-line binds — timestamps + filter
-  language at `RuntimeCommunicationState.AddText`; daylight
-  (`ForcedDayGroupIndex`), weather, fog; run-as-default in
-  `RuntimeLocalPlayerMovementState`; main-pack default at the pickup path;
-  the UI-display bits at their existing retained controllers. Group C
-  re-pointing per D7. Group A wire+store only. Group D register rows.
- Conformance test: all 50 rows ↔ table ↔ storage bit ↔ wire route pinned
-  in both directions (the CH4 registry-conformance pattern — an invented
-  row or a dropped row fails the build).
-
-**Register rows:** group D deferrals (salvage, housing, fellowship-share
-field, PK-deaths already rowed in OP1, mouse-turning row lives in OP3);
-each group-C re-point that changes an observable default.
-
-**Gate:** connected — LED rows toggle + persist across relogin (server
-echo), timestamps/daylight/fog/weather/run-default observably switch, Apply
-/ Reset / Defaults exercise retail semantics, tab-switch reverts
-uncommitted edits.
-
-### OP5 — the Chat tab
-
-**Files.** Create
-`src/AcDream.App/UI/Layout/ChatOptionsPageController.cs` binding
-`0x2100005C` root `0x1000050A`: the two LINKED opacity sliders (bound to
-the existing `RetailWindowOpacityController` values through
-`ChatOpacityLink` — AP-190's model, now user-reachable) and the five
-per-window filter blocks (SetUserData ids 8/2/3/4/5; main window 12 rows,
-floaties 13 — lane A §8's byte-decoded masks) writing the per-window filter
-state CH6 already consumes (`ChatWindowState.ShouldDisplay`). The
-`0x1000008C` per-window blob stays local-only (already-anticipated register
-row from `2026-08-09-chat-retail-window-shell.md` §6.3 — cite, don't
-duplicate).
-
-**Gate:** connected — filter checkboxes change window routing live;
-opacity sliders drive the focus fade; settings survive relogin locally.
-
-### OP6 — the Config tab
-
-**Files.** Create
-`src/AcDream.App/UI/Layout/ConfigOptionsPageController.cs` binding
-`0x21000029` root `0x100001FF`: all 27 rows in lane A §9 / lane D §7.3's
-authored order, backed by acdream's client settings store
-(`%LOCALAPPDATA%\acdream\` — the D1 home). Rows with live subsystems bind
-now: the three volume trios → the audio pipeline, "play sound only when
-active", mouse-look sensitivity + invert Y, FOV, chat font size/face if the
-chat pipeline exposes them. Rows without a subsystem (resolution +
-fullscreen + sync, degrades, texture detail family, multi-pass alpha)
-persist store-only under ONE register row enumerating them (the goal's
-"honest store-only handling"); resolution's `SetConfirmChange` flow ships
-whenever the consumer lands, not now.
-
-**Gate:** connected — audio sliders audibly change mix; mouse sensitivity
-observably changes; store-only rows persist across relaunch.
-
-### OP7 — headless `characterOptions`
-
-**Files.** Modify
-`src/AcDream.Headless/Configuration/HeadlessConfiguration.cs` +
-`HeadlessConfigurationLoader.cs`: optional `characterOptions` block, strict
-— keys are exactly the lane B §5.2 tier-1+2 option NAMES, values bool;
-unknown key = load failure (D8). Modify the session host
-(`src/AcDream.Headless/Hosting/`) to diff declared vs
-PlayerDescription-seeded state after LoginComplete and send changes through
-the shared seam (auto-save ids as `0x0005`, remainder via one
-`SaveOptions` blob), honouring #368's one-dedicated-update-thread contract.
-Idempotent on reconnect (retail itself no-ops unchanged options — lane C
-§3.5). Headless tests: schema rejection, diff-only sends, reconnect
-idempotence, thread affinity preserved.
-
-**Gate:** automated + one live bot-vs-local-ACE run (no graphical client)
-showing declared options land and survive reconnect.
-
-### OP8 — Configure Keyboard
-
-**Files.** Create
-`src/AcDream.App/UI/Layout/KeyboardConfigController.cs` (+ a
-`src/AcDream.Core/...` DAT `ActionMap` (DBO type `0x27`) reader if
-`DatCollection` lacks one): `gmKeyboardUI`'s six ActionClass list boxes
-via OP2's Type 5 widget, rows = label + tooltip + N key buttons + Clear
-from the DAT master maps (DIDs `0x14000000`/`0x14000002` — the exact
-enum→DID pairing is lane D unknown #4, resolved in-slice by dumping both),
-merged with live `KeyBindings`; left-click key button → `InputDispatcher`
-modal capture; right-click erases; N-way cross-map conflicts + the
-non-user-bindable refusal per lane D §5; Save/Cancel; Reset-to-defaults
-reloads the DAT maps. Persistence: `keybinds.json` (D4).
-
-**Register rows:** `.keymap` file interchange not implemented (D4); any
-retail column/behaviour consciously narrowed.
-
-**Gate:** connected — rebind a movement key, conflict prompt on a taken
-chord, persistence across relaunch, reset restores retail defaults.
-
-### OP9 — closeout
-
- Retire `SettingsPanel`/`SettingsVM`'s IPanel surface +
-  `SettingsDevToolsComposition` wiring + `DevToolsGameplayCommands`
-  no-ops; delete `GameplaySettings`' 16 server-shadowed booleans (lane B
-  §7.2.5), re-scoping true client-only settings into the D1 store. Every
-  deletion checked against consumers; no behaviour regression.
- Bookkeeping: plan status flips, ISSUES sweep (#358 retest against OP8's
-  screen — its Ctrl+M lesson lives in `RetailDefaults()`), register
-  reconciliation, CLAUDE.md Current-state paragraph (per
-  `feedback_claude_md_staleness`), memory digest update
-  (`project_chat_digest` addendum or a new settings digest).
- Write `docs/research/2026-08-10-campaign-op-test-script.md`: the
-  connected-gate script covering every OP3–OP8 gate item, per-tab, with
-  expected retail behaviours — the campaign's stop condition is this
-  script ready plus all slices code-complete.
-
-**Gate:** the user's final connected matrix (their eyes, their pace).
-
---
-
-## 5. What is explicitly OUT of scope
-
- Packing the `0x200` GameplayOptions blob section (per-window chat state
-  on the wire) — a follow-on (CH6f shape), pre-anchored by lane C U1 and
-  `2026-08-09-chat-retail-window-shell.md` §6.3's register row.
- A pre-world character-select flow (D6 adapts; its register row carries
-  the future work).
- Retail `.keymap` file read/write (D4 register row).
- The `0x21000017` docked `gmPanelUI` host variant — acdream ships the
-  floating host only (register row in OP3 if the review deems it a
-  divergence; retail exposes both).
-
-## 6. Verification discipline
-
-Per commit: `dotnet build` + FULL Release suite green (baseline at plan
-time: 12,611 / 4 skips / 0 failures at `29138430`+). Golden byte vectors
-for every wire builder. Conformance pins for every authored inventory
-(row lists, template arrays, tab table, checkbox masks). Register rows in
-the SAME commit as the deviation. No user-visible placeholder text ever —
-all user-facing strings resolve from the DAT string tables
-(`0x23000001`/`0x23000003`) by `compute_str_hash` name, never hard-coded
-English.
-
-## 7. Review protocol
-
-Dual-lens Opus review per slice (mechanism-faithfulness lens ×
-regression/blast-radius lens), fixes applied by the implementer; REJECT →
-focused re-review; TWO failures → Fable fixes directly (user-directed
-2026-08-10). Review findings that feed both a fixer and a re-reviewer are
-persisted to a committed findings doc BEFORE dispatch.
-
-## 8. Process rules (binding, inherited from Campaign CH via the handoff)
-
-Max 3–4 agents in parallel INCLUDING children; every agent prompt carries
-an explicit no-subagent clause; ONE builder/tester on the tree at a time
-(read-only research may overlap); agents never launch the graphical
-client; the user runs all connected gates; screenshots transcribed into
-docs immediately; ledger placeholders anchored per-row, post-amend SHAs
-recorded by the coordinator; decomp claims byte-verified against the
-PDB-paired binary (`check_exe_pdb.py` MATCH first); stalled agents resumed
-via SendMessage before any redo; agent claims spot-verified at the seams
-before anything builds on them.
-

-# Campaign LA — launcher / installer / updater + retail character-select
-
-**Status:** ACTIVE (started 2026-08-14)
-**Spec (approved):** `docs/superpowers/specs/2026-08-14-launcher-campaign-design.md`
-**Memory crib:** `claude-memory/project_launcher_direction.md`
-**Branch:** `claude/acdream-launcher-credentials-4d2f7c` (merge to main at coherent checkpoints)
-
-Campaign LA ships the alpha launcher (Avalonia, Windows + Linux): triple-duty
-launcher + installer + updater, ThwargLauncher-model profiles with full in-UI
-CRUD, plaintext credential file (user-decided), file-contract orchestration of
-`AcDream.App` and `AcDream.Headless`, plugins + login commands on both hosts,
-the headless character probe, and the retail character-select screen (no
-Create). All architectural decisions live in the spec — this plan sequences
-the work.
-
-## Process (binding)
-
- **Fable plans/sequences/integrates. Sonnet implements bounded slices. Opus
-  reviews at every slice boundary, dual-lens:** (a) architectural — ownership,
-  layering, dependency-guard integrity, seams; (b) retail fidelity vs
-  `docs/research/named-retail/` wherever the slice touches retail behavior.
-  Findings → fixes → narrow re-review.
- Max 3–4 agents in parallel including children; subagents never spawn
-  subagents; implementer prompts carry spec+plan paths, files-to-read,
-  acceptance criteria, commit style.
- `dotnet build` + `dotnet test` green before a slice is DONE; ≥1 commit per
-  slice tagged `Campaign LA`; retail deviations add their
-  `docs/architecture/retail-divergence-register.md` row in the same commit;
-  no workarounds without explicit user approval.
- Connected/visual gates are the ONLY stop-and-wait points; each gets an
-  exact script under `docs/research/` and non-blocked slices keep moving.
-
-## Slice map
-
-| Slice | Deliverable | Depends on |
-|---|---|---|
-| LA0 | `AcDream.Platform` extraction (`ApplicationPathSet`) + guard amendments | — |
-| LA1 | Launch contract: App `--session-config` + stdin credential; status.jsonl writer both hosts; roster plumbing | LA0 |
-| LA2 | Headless probe mode + `idle` policy | LA1 |
-| LA3 | `AcDream.Launcher.Core`: profile store CRUD, config composition, spawn/supervise, status reader | LA0 (LA1 contract shapes) |
-| LA4 | `AcDream.Launcher` Avalonia UI: CRUD views, per-char settings, sessions, probe action | LA3 |
-| LA5 | Plugin hosting: headless `IPluginHost` + capability flag; session-driven plugin set both hosts | LA1 |
-| LA6 | Login commands: parser-core extraction + execution on both hosts | LA1, LA5 |
-| LA7 | Character-select: Runtime selection state + wire (delete/restore/error) + no-selector flow | LA1 |
-| LA8 | Character-select authored retail screen (flat listbox — NO 3D preview, recon-corrected) | LA7 |
-| LA9 | Installer: first-run wizard (DAT locate/validate, bake w/ progress, SHA record) | LA3, LA4 |
-| LA10 | Updater: GitHub Releases manifest, download/verify/install/swap, self-update | LA3, LA4 |
-| LA11 | Closeout: connected-gate script, roadmap/CLAUDE.md/memory, program ledger | all |
-
-Parallelism guide: LA3/LA4 (launcher side) proceed alongside LA5–LA8 (client
-side) — different assemblies, no shared files. LA9/LA10 close the launcher
-side; LA11 closes the campaign.
-
-## Linux posture (binding — user decision 2026-08-14)
-
-Everything the launcher does must WORK ON LINUX in this campaign, except
-GUI client launches: the Linux graphical client is Slice L, parked at L1,
-resuming later ("ok we will do it later"). Concretely:
-
- **Linux-shipping in LA:** the Avalonia launcher UI, profile CRUD +
-  0600-permission file, installer (manual DAT picker — the auto-detect
-  paths are Windows-only; `acdream-bake` is GL-free and runs on Linux),
-  updater (staged swap; Linux can replace a running binary but keep the
-  same staged-atomic flow), headless launches with plugins + login
-  commands, and the character probe.
- **Launcher UX on Linux:** the `gui` / `guiSelect` launch modes render
-  disabled with an explicit "requires the Linux graphical client (Slice
-  L)" note — never a silent failure.
- **Per-slice enforcement:** every slice touching Launcher.Core, Headless,
-  Runtime, Bake, or Platform runs its test projects on Linux (native
-  Ubuntu or WSL, matching the K-slice practice) before the slice is DONE;
-  LA4/LA9/LA10 additionally prove a real `linux-x64` self-contained
-  publish. LA11's connected-gate script gets a Linux section: launcher on
-  Ubuntu doing CRUD, probe, headless launch with plugin + login commands,
-  first-run install with a manual DAT path, and an update swap.
- When Slice L later ships, the launcher's Linux GUI modes light up with
-  NO launcher changes (the session-config contract is host-agnostic) —
-  that expectation is part of LA's design acceptance.
-
-## LA0 — `AcDream.Platform` extraction
-
-New BCL-only project `src/AcDream.Platform/` holding `ApplicationPathSet` +
-`IApplicationPathEnvironment` (today
-`src/AcDream.Runtime/Platform/ApplicationPathSet.cs` — self-contained, no
-intra-Runtime dependencies; clean cut). Runtime/App/Headless reference it.
-
-Recon facts (2026-08-14): blast radius is the definition, six source files
-(`GraphicalHostPlatformServices.cs`, `GraphicalLegacyConfigurationMigrator.cs`,
-`App/Program.cs`, `GameWindow.cs:533`, `HeadlessPathSet.cs`,
-`HeadlessPlatformEnvironment.cs`; two more files are doc-comment-only), two
-test files (`ApplicationPathSetTests.cs` moves to a new
-`tests/AcDream.Platform.Tests/`;
-`GraphicalLegacyConfigurationMigratorTests.cs` fixtures), and the dependency
-guards — CORRECTED post-review (the original recon here asserted the wrong
-guard, the C4-closeout failure mode): the K0 Headless guard
-(`HeadlessAssemblyReferencesOnlyTheRuntimeProject`) asserts HEADLESS's own
-csproj reference list, which this move does not touch — it stays UNCHANGED;
-the guard that actually needs amending is Runtime's own
-`RuntimeDependencyBoundaryTests.RuntimeProjectDeclaresOnlyApprovedProjectDependencies`
-(Runtime gains the `AcDream.Platform` reference), amended with a cited
-comment in the same commit. Namespace stays `AcDream.Runtime.Platform`?
-NO — rename to `AcDream.Platform` and fix the eight usings (clean naming beats
-avoiding a mechanical edit). Register new projects in `AcDream.slnx`.
-
-**Acceptance:** build + full test suite green; guard test asserts the new
-exact reference set; launcher-side consumability proven by the LA3 project
-referencing only `AcDream.Platform`.

-## LA1 — launch contract (client side)
-
-### Pinned launch-contract schema (v1, BINDING — committed per LA3 review)
-
-This text is the single source of truth for the launcher↔host file
-contract. Both host readers (LA1), the composer (LA3), and the probe
-loader (LA2) implement EXACTLY this; any change is an amendment to THIS
-section first, implementations second. The LA1+LA3 merge adds a
-cross-assembly test feeding a composer-produced document to both host
-loaders — that test is the seam's permanent enforcement.
-
-Session-config document (System.Text.Json, camelCase,
-`UnmappedMemberHandling.Disallow`, camelCase string enums):
-
-```json
-{
-  "version": 1,
-  "process": {
-    "content": { "datDirectory": "...", "preparedAssetPath": "..." }
-  },
-  "sessions": [{
-    "id": "sess-1",
-    "endpoint": { "host": "127.0.0.1", "port": 9000 },
-    "account": "testaccount",
-    "mode": "probe",
-    "character": { "id": 1342177290 },
-    "policy": { "id": "idle" },
-    "credential": { "provider": "standardInput", "reference": "session" },
-    "plugins": ["ExamplePlugin"],
-    "loginCommands": ["/vt start"],
-    "loginCommandDelayMs": 500,
-    "statusFile": ".../launcher/sessions/sess-1/status.jsonl"
-  }]
-}
-```
-
-Field rules:
- `process.paths` is OMITTED unless a caller genuinely supplies overrides
-  (never an empty object — the App reader has no `paths` member and
-  strict parsing rejects unknown keys; LA3 review finding 1).
- `mode`: ABSENT for normal play sessions; `"probe"` for the LA2 probe
-  (connect → characterList → graceful disconnect, no EnterWorld). The
-  headless loader accepts the field starting at LA2.
- `character`: exactly ONE of index|id|name; OMITTED entirely (not null)
-  for guiSelect and for probe sessions.
- `policy`: `{ "id": "idle" }` for headless play sessions ONLY; omitted
-  for gui/guiSelect/probe.
- `credential`: always `{ "provider": "standardInput", "reference":
-  "session" }` for launcher-composed configs.
- `plugins`: absent/null means load all discovered plugins (preserving the
-  developer flow); explicit `[]` means load none. Launcher-composed
-  normal-empty and probe sessions emit `[]` so they cannot load arbitrary
-  machine-local plugins.
- `loginCommands`/`loginCommandDelayMs`/`statusFile`: optional,
-  omitted-when-unset (never null, never `[]` for empty). Absent
-  `loginCommandDelayMs` means 500.
-
-Status stream (`statusFile`, one JSON object per line, writer flushes per
-line, writer opens `FileShare.Read`, tailer opens
-`Read/FileShare.ReadWrite|Delete`): events `started`, `connected`,
-`characterList{accountName,slotCount,characters[{id,name,secondsGreyedOut}]}`,
-`enteredWorld{characterId,characterName}`, `pluginLoaded{plugin}`,
-`pluginFailed{plugin,error}`,
-`loginCommandFailed{commandIndex,command,error}`,
-`characterCreated{guid,name}`, `creationFailed{code,reason,name}`,
-`disconnected{reason}`,
-`exited{code,reason}` — every line carries `"v":1`, `"e"`, `"t"`
-(ISO-8601 UTC), `"sessionId"`. `secondsGreyedOut` is a uint on BOTH
-sides. Unknown `e` values must parse to a typed Unknown event, never
-throw; a known `e` with a wrong payload shape should be distinguishable
-from an unknown `e` (LA3 review finding 12).
-
-**Campaign CC CC2 amendment (this section is the contract; the writer and
-tailer below implement it, in that order):** `characterCreated{guid,name}`
-fires on the Ok reply to a `CharacterCreate` (opcode `0xF656`) request —
-`guid`/`name` come straight off the shared `0xF643`
-`CharGenVerificationResponse` Ok identity payload
-(`AcDream.Core.Net.Messages.CharGenVerificationResponse`), deliberately
-named `guid`/`name` rather than `characterId`/`characterName` to mirror
-that payload's own field names and to read distinctly from
-`enteredWorld` — a freshly created character is logged straight in by
-retail without a fresh `characterList` (see that type's doc comment), so
-`characterCreated` can precede an `enteredWorld` for the same character
-rather than replacing it. `creationFailed{code,reason,name}` fires on any
-non-Ok reply: `code` is the raw wire `CharGenVerificationResponse.Code`
-value, `reason` is that code's enum member name (e.g. `"NameInUse"`) so a
-reader gets a stable readable reason without hard-coding the numeric
-mapping itself, and `name` is the ATTEMPTED character name so a launcher
-can render "the name Bob is taken". (CC2 review F4: the enum member
-originally rode the `name` key, colliding in meaning with
-`characterCreated.name`; renamed before any consumer shipped.)
-
-`loginCommandFailed.commandIndex` is the zero-based index in the configured
-`loginCommands` array. `command` is the exact configured line and `error` is
-the isolated parser/router/handler failure. The event is observational: the
-host continues with the next configured line and never converts the command
-failure into a login, plugin, session, or process failure.
-
-**Known LA1 status limitation:** the stream has no independent mid-play
-wire-drop detector. If a transport becomes silent without raising through the
-host's tick/teardown path, no immediate `disconnected` line can be promised;
-the launcher must not treat the absence of that line as proof that the socket
-is healthy. Explicit reconnect is ordered and observable — it emits
-`disconnected{reason:"reconnect"}` before the replacement connection's second
-`connected` — and normal stop/process teardown closes any still-open
-connection before `exited`. A future transport-health signal may improve the
-timing without changing this pinned event vocabulary.
-
-Three pieces, one slice, because they share the session-config/status seam:
-
-1. **App `--session-config <path>`:** parsed once in `Program.cs` into
-   `RuntimeOptions` (code-structure rule 4); carries endpoint, account,
-   optional character selector, `Plugins`, `LoginCommands`, `Content`
-   (DatDirectory/PreparedAssetPath), status-file path, credential reference.
-   Recon: `Program.cs` has NO subcommand dispatch today — args handling is
-   one positional DAT-dir (`Program.cs:35`), so the flag is purely additive
-   (preserve the positional arg). The live-credential seam is a single call
-   site (`SessionPlayerComposition.cs:1128-1135` →
-   `LiveSessionConnectOptions`); the config path populates the same
-   `RuntimeOptions` fields from a different source. Env-var dev flow
-   untouched. App gains the `StandardInput` credential read (mirroring
-   `HeadlessCredentialResolver.ResolveStandardInput` — one line, immediately
-   wrapped in an erasable secret, redacted `ToString`; today
-   `RuntimeOptions.LivePass` is a bare string — the config path must not
-   widen that exposure).
-2. **Status stream both hosts:** per-session `status.jsonl` (path given in
-   config; absent → permanent no-op sink). Versioned event
-   vocabulary (`"v":1`): `started`, `connected`, `characterList`,
-   `enteredWorld`, `pluginLoaded`/`pluginFailed`,
-   `loginCommandFailed`, `characterCreated`/`creationFailed` (Campaign CC
-   CC2), `disconnected`, `exited`.
-   Recon: today's `HeadlessDiagnosticWriter` is a single shared-stdout JSONL
-   sink with four kinds (lifecycle/failure/event/resources) and NO per-session
-   file — the status writer is a second, separate sink, not a rework of the
-   diagnostics writer. App has no structured writer today; it gets the same
-   shared implementation (lands in Runtime so both hosts borrow it).
-3. **Roster plumbing:** `CharacterList.Parsed` is consumed inside
-   `LiveSessionController.StartCore` (`LiveSessionController.cs:612`) and
-   never escapes — add a typed roster report on the lifecycle-host seam
-   (`ILiveSessionLifecycleHost`) so hosts can emit the `characterList` status
-   event and (later) the char-select screen can populate. No behavior change
-   to selection itself in this slice.
-
-**Acceptance:** round-trip tests (config → `RuntimeOptions`; stdin credential;
-status events in order with exact shapes; roster surfaced); App/Headless/
-Runtime suites green; redaction test proves the password never appears in
-status/diagnostics output.
-
-## LA2 — headless probe mode + `idle` policy
-
-Recon facts: the probe's shape already exists as the `NoCharacters` early-exit
-(`LiveSessionController.cs:613-622` → `StopCore()` → 4-stage
-`SessionScope.DrainTeardown`, graceful, `_inWorld == false` so no pre-logoff
-flush) — but it fires only on selection FAILURE and maps to exit code 5
-(`HeadlessProcessHost.RunOnUpdateThread:203-212` treats any non-`Connected`
-start as `ConnectionError`).
-
-1. **Probe:** a `Probe` flag on the connect options short-circuits `StartCore`
-   right after `GetCharacters` (before `TrySelectCharacter`): report roster,
-   `StopCore()`, return a NEW `LiveSessionStartStatus.ProbeComplete`.
-   `HeadlessProcessHost` maps it to exit code 0 with a final `characterList` +
-   `exited(reason: "probe")` status pair. Config: `mode: "probe"` on the
-   session descriptor relaxes the `JsonRequired` character selector + policy
-   for probe sessions ONLY (loader keeps strict validation otherwise —
-   recon: violations currently surface as raw `JsonException` → exit 3; probe
-   relaxation must be shape-level in the loader, not attribute removal).
-2. **`idle` policy:** new consumer `HeadlessBotPolicy` id — enter world, run
-   plugins/login-commands (arrive in LA5/LA6), stay until stopped, clean
-   SIGINT teardown (K4's graceful-logout path already proves the mechanism).
-
-**Acceptance:** probe test (fixture session → roster event → graceful teardown
-receipt → exit 0, no `EnterWorld` on the wire); loader tests for probe-shape
-relaxation + strict normal validation; idle-policy lifecycle test; suites
-green. Connected verification (user gate, LA11 batch): live probe against ACE
-twice in a row with no lingering session (spec §11.9).
-
-## LA3 — `AcDream.Launcher.Core`
-
-New BCL-only project + `tests/AcDream.Launcher.Core.Tests/`. References
-`AcDream.Platform` ONLY.
-
- Profile store: `launcher-profiles.json` (spec §5 schema) — load/save/
-  validate, full CRUD operations, roster merge (fold `characterList` events
-  in, preserving per-character user settings), 0600 on Linux.
- Session-config composition: profile + install records → the LA1 config
-  shape (typed writer; probe shape included). Passwords excluded — stdin only.
- Process orchestration: spawn App/Headless per launch mode, feed password to
-  child stdin then close, supervise lifetime, tail `status.jsonl`
-  (share-tolerant reads), surface typed session state.
- SHA-256 utility (pak record + download verify — consumed by LA9/LA10).
-
-**Acceptance:** CRUD/round-trip/merge tests; composition tests (all three
-modes + probe); supervision tests against a fake child process (echo script);
-status-tail tests including partial-line handling; suites green.
-
-## LA4 — `AcDream.Launcher` (Avalonia)
-
-New Avalonia project (Windows + Linux). MVVM over Launcher.Core; no game
-solution references beyond `AcDream.Platform` transitively.
-
- Views: server list → accounts → characters tree; add/edit/remove dialogs
-  for servers (name/host/port) and accounts (account + password entry);
-  per-character settings editor (launch mode, plugin set, login commands);
-  per-account "refresh characters" (probe); running-sessions status column.
- Launch actions per mode (`gui` / `guiSelect` / `headless`); probe disabled
-  while the launcher runs a session for that account.
- First-run wizard shell + update prompt shell (bodies land in LA9/LA10).
-
-**Acceptance:** ViewModel tests in Launcher.Core.Tests patterns (VMs live in
-the Avalonia project but stay logic-thin; anything testable pushes down);
-build green on Windows; `linux-x64` publish compiles. Visual polish is gated
-at LA11 (user).
-
-## LA5 — plugin hosting on both hosts
-
-Recon facts (2026-08-14): `PluginLoader`/`PluginDiscovery`/`PluginManifest`
-already live in `AcDream.Core` (Headless-reachable). App's single load loop
-(`App/Program.cs:110-121`) loads ALL discovered plugins from two roots
-(`AppContext.BaseDirectory/plugins` + `ApplicationPathSet.PluginsDirectory`,
-dup-id skip) — no allow-list exists on either host. `AppPluginHost` is a
-26-line pass-through; three of four `IPluginHost` surfaces (`State` →
-`WorldGameState`, `Events` → `WorldEvents`, `Selection` → `SelectionState`)
-are backed by Core-owned types already; only `Ui` (`BufferedUiRegistry`) is
-genuinely App-only. Headless has zero plugin hosting today (confirmed).
-
-1. Session-config `Plugins` allow-list filters the discovery result on BOTH
-   hosts (absent/null list = load all, preserving today's dev behavior;
-   explicit `[]` = load none). Launcher-composed normal-empty and probe
-   sessions emit `[]`.
-2. `HeadlessPluginHost : IPluginHost` in Headless over the same Core-owned
-   `State`/`Events`/`Selection`; `Ui` is an explicit no-op behind a new
-   capability flag on `IPluginHost` (e.g. `HasUi`) so plugins can detect
-   headless. Contract documented in `Plugin.Abstractions`.
-3. `pluginLoaded`/`pluginFailed` status events from both hosts' load loops.
-
-**Acceptance:** fixture plugin in Headless suite (load, capability flag,
-markup no-op, teardown via collectible ALC); allow-list filter tests both
-hosts; status events asserted; suites green.
-
-## LA6 — login commands on both hosts
-
-Recon facts (2026-08-14): the command core is dependency-CLEAN —
-`ChatInputParser` (zero usings), `ChatCommandRouter` (BCL +
-`AcDream.Core.Chat`), `RetailClientCommandCatalog` (FrozenDictionary),
-`ChatVM` (Core.Chat/Combat + `System.Numerics` only), `ICommandBus` + the
-four command records (BCL-only). The block is assembly identity, not
-coupling. `ChatCommandRouter.Submit`'s two entanglements: a hard `ChatVM`
-parameter (uses only `ShowInterfaceText`/`ShowSystemMessage`/
-`LastIncomingTellSender`/`LastOutgoingTellTarget`) and the `ICommandBus`,
-whose production implementation (`LiveSessionCommandRouter`,
-`App/Net/LiveSessionCommandRouter.cs`) is App-only and wraps wire-send
-delegates from the live session. GUI already has a login-command analog:
-`RetailUiAutomationScriptRunner` feeds `ChatCommandRouter.Submit` at
-`RetailUiRuntime.cs:523-527`.
-
-1. **Extraction:** move parser/router/catalog + `ICommandBus` + the four
-   command records (+ sibling tables they require) into Runtime
-   (`AcDream.Runtime/Chat/...`); the router's `ChatVM` parameter becomes a
-   narrow feedback interface defined beside it (exactly the four members
-   used); `ChatVM` (stays in UI.Abstractions) implements it. GUI path stays
-   bit-identical — same call sites (`ChatWindowController.cs:326`,
-   `FloatingChatWindowController.cs:157`), same routing, CH-accepted
-   behavior regression-checked by the existing chat suites.
-2. **Headless dispatch:** a Runtime/Headless `ICommandBus` binding the same
-   session send delegates (`SendTalk`/`SendTell`/`SendChannel`/
-   `SendTurbineChat`) + Runtime state that App's router binds — paralleling
-   `LiveSessionCommandRouter`'s registrations, feedback lands in
-   `RuntimeCommunicationState.AddText`.
-3. **Execution:** both hosts run `LoginCommands` sequentially as-if-typed
-   (default 500 ms inter-command delay, config-overridable) once
-   entered-world; per-command failures → status stream, never abort.
-4. K0 guard: if the code folds into Runtime, the single-reference assertion
-   stands untouched; the forbidden-prefix closure tests keep passing. Any
-   guard text change is deliberate and documented.
-
-**Acceptance:** extraction lands with zero GUI chat test regressions
-(UI.Abstractions + App chat suites bit-green); headless executes a
-login-command script against a fixture session with ordered wire sends;
-delay + failure-tolerance tests; suites green.
-
-## LA7 — character-select: state + wire
-
-Recon facts (2026-08-14): retail's screen is `gmCharacterManagementUI`
-(`acclient.h:56545`) — flat listbox + Create/Enter/Delete/Restore buttons +
-dialog contexts. **No 3D preview exists on retail's select screen** (the
-`gmCG3DView`/`CreatureMode` viewport is chargen-only; the old
-"rotating pedestal" line in `retail-ui/05-panels.md` §13 is uncited and
-wrong). Our `CharacterList` parse already matches ACE's serializer exactly
-(two-array shape, status/deleted always zero from ACE) and the two-phase
-enter-world (0xF7C8 → 0xF7DF → 0xF657) is implemented. Missing wire:
-delete/restore/error.
-
-1. **Wire messages** (`AcDream.Core.Net/Messages/`, retail citations in
-   file docs per house style): `CharacterDelete` 0xF655 — outbound
-   account String16L + **slot index** (`Proto_UI::SendDeleteCharacter
-   @0x00546b30`; NOT guid), inbound opcode-only ack followed by a fresh
-   CharacterList; `CharacterRestore` 0xF7D9 guid-only (ACE + holtburger
-   consensus; the decomp's apparent extra strings are a decompiler
-   artifact — spec §11.4), response 0xF643 (flag + guid + name +
-   secondsDisabled); `CharacterError` 0xF659 parser (new — today NO
-   character-stage server error can be surfaced).
-2. **Runtime selection state** (J-owner pattern): roster with per-entry
-   greyed/pending-delete state (`SecondsGreyedOut != 0` ⇒ pending; ACE
-   sends a constant 1 during the grace window — treat as boolean, never a
-   countdown), highlight, pending-delete dialog state, typed commands
-   (highlight / enter / delete-request / delete-confirm / restore).
-   Retail behavior oracles: `RebuildCharacterList@0x004ec3a0`,
-   `SelectCharacter@0x004ec160`, `UpdateButtons@0x004ec240`
-   (Delete↔Restore swap on greyed state), `EnterGame@0x004ed440`.
-3. **No-selector flow:** a graphical session config without a character
-   selector stops at selection state instead of auto-enter; the
-   first-available fallback (`CharacterList.TrySelectFirstAvailable`,
-   used at `LiveSessionController.cs:848-851`) remains ONLY for
-   selector-carrying/headless sessions. Selection feeds the existing
-   `EnterWorld` path unchanged.
-
-LA7b hazards carried from the LA7a review (2026-08-14): ACE's restore
-handler has a SILENT no-reply path (unknown guid → `return;`, no 0xF643,
-no 0xF659) — selection state must never block awaiting a restore reply;
-outbound routing is delete via retail's SendToLogon, restore via
-SendToControl, ACE replies on UIQueue; `charError.NumErrors` (0x19) is an
-enum-range sentinel and must never render as a user-facing message.
-Register row AD-97 (guid-only restore request, an adaptation) rides the
-LA7a branch.
-
-**Acceptance:** message round-trip tests against ACE's serializer shapes;
-selection-state tests (greyed transitions, delete→list-refresh, restore,
-error surfacing); no-selector stop + enter flow tests; suites green.
-
-## LA8 — character-select: authored retail screen
-
-Scope: project LA7's state through the REAL retail screen. No 3D preview
-(recon-corrected; a preview would be an unapproved divergence).
-
-1. **Layout resolution:** retail resolves the root via
-   `UIMainFramework::CreateAndAddRootElement(0x10000005, 0x1000039a)` +
-   `DBObj::GetDIDByEnum(..., 5)` — reuse OP8's ported GetDIDByEnum
-   machinery (category 4 precedent) for enum-table 5; slice starts by
-   dumping that table from installed DATs to pin the concrete DataID.
-   Child ids: listbox `0x1000039d`, create `0x100003a0` (present,
-   disabled — Create is a future campaign), enter `0x100003a2`, delete
-   `0x1000039f`, restore `0x1000039e`.
-2. **Dialogs:** delete-confirm, please-wait, entering-world, error — the
-   retail dialog machinery from the OP8 WaitDialog work (`2a81e813`
-   mapped WaitDialog class type 0x19) is the base.
-3. **Open item resolved here:** whether retail draws a render-loop
-   background scene behind the UI (pseudo-C proves only that the UI class
-   owns no viewport) — settle via user recollection + the visual gate
-   before polishing.
-
-**Acceptance:** authored screen builds from DAT assets; button-state
-matrix matches `UpdateButtons` oracle (incl. Delete↔Restore swap);
-enter/delete/restore/error flows drive LA7 state end-to-end; suites
-green. User visual gate at LA11 (screen look, dialog flows, delete +
-restore against local ACE).
-
-## LA9 — installer (first-run)
-
- DAT locate: auto-detect `%USERPROFILE%\Documents\Asheron's Call` and
-  `C:\Turbine\Asheron's Call` + manual picker; validate the four DATs.
- Bake: spawn `acdream-bake --dat-dir <dats> --out <DataDirectory>/pak/acdream.pak
-  --threads N`. Recon: default `--out` is INSIDE the DAT dir — the launcher
-  always passes `--out` explicitly. Progress: add `--progress-json` to
-  `AcDream.Bake` (JSONL progress lines alongside the existing 5-second human
-  text, which stays default) — scraping human text is fragile and we own the
-  tool. Recon: the bake has NO whole-file SHA — after a successful bake the
-  LAUNCHER computes and records SHA-256 + size + `BakeToolVersion` in its
-  install record, and re-verifies on subsequent startups (fast corruption
-  check trades a few seconds of hashing for never launching against a
-  half-written pak).
- Install record feeds LA3's session-config composition
-  (DatDirectory/PreparedAssetPath).
-
-**Acceptance:** wizard flow tests over Launcher.Core (fake bake child emitting
-`--progress-json` lines); bake-tool progress flag tests in
-`tests/AcDream.Bake.Tests`; SHA record/verify tests; suites green. Connected
-gate (user): clean-profile first-run against real DATs.
-
-## LA10 — updater
-
- Manifest: GitHub Releases; `manifest.json` release asset — version, per-RID
-  client zip URL + SHA-256 + size, minimum-launcher version. Launcher pins
-  owner/repo in its config.
- Client update: poll on launch (+ manual check), download to staging, SHA
-  verify, unpack to `DataDirectory/app/<version>/`, atomic `current.json`
-  pointer swap, refuse while any session runs, keep previous version for
-  one-step rollback.
- Launcher self-update: staged download + target-local atomic replacement on
-  next start.
- Session-config composition targets `app/current`'s binaries.
-
-**Acceptance:** manifest/download/verify/swap tests against a local HTTP
-fixture; rollback test; refusal-while-running test; self-update staging test;
-suites green. Connected gate (user): staged-manifest update swap end-to-end.
-
-### Pinned updater contracts (v1, BINDING)
-
-This section is the single source of truth for every LA10 feed and on-disk
-shape. Readers use strict, case-sensitive `System.Text.Json` parsing, reject
-unknown or duplicate properties, and reject unsupported schema versions
-before doing network, extraction, or activation work.
-
-The production feed is pinned to GitHub owner/repository
-`eriknihlen/acdream`; the launcher reads
-`https://github.com/eriknihlen/acdream/releases/latest/download/manifest.json`.
-Tests use a separate internal fixture constructor that may admit loopback HTTP;
-that allowance never propagates to the production feed. Production manifest
-and artifact URIs use HTTPS. Automatic redirects are disabled and every
-redirect hop is validated before it is requested; redirect loops, a chain over
-five hops, and any HTTPS-to-HTTP downgrade are rejected. `manifest.json` is:
-
-```json
-{
-  "schemaVersion": 1,
-  "version": "1.2.3",
-  "minimumLauncherVersion": "1.1.0",
-  "clients": {
-    "win-x64": {
-      "url": "https://github.com/eriknihlen/acdream/releases/download/v1.2.3/acdream-client-win-x64.zip",
-      "sha256": "<64 hex characters>",
-      "size": 123
-    }
-  },
-  "launchers": {
-    "win-x64": {
-      "url": "https://github.com/eriknihlen/acdream/releases/download/v1.2.3/acdream-launcher-win-x64.zip",
-      "sha256": "<64 hex characters>",
-      "size": 123
-    }
-  }
-}
-```
-
-`version` and `minimumLauncherVersion` are strict SemVer 2.0 strings. Build
-metadata is ignored for precedence; numeric identifiers are compared without
-fixed-width integer overflow. RID keys are exact lowercase portable RIDs.
-Both dictionaries are required and the running RID must have a client and a
-launcher row. Artifact sizes are positive and capped by the launcher's
-download limit; SHA-256 is exactly 64 hex characters. ZIP URLs are absolute.
-Client ZIPs have the two host executables at their root
-(`AcDream.App[.exe]`, `acdream-headless[.exe]`); launcher ZIPs have
-`acdream-launcher[.exe]` at their root. No implicit wrapper directory exists.
-
-Every extracted client version has
-`DataDirectory/app/<version>/install.json`:
-
-```json
-{
-  "schemaVersion": 1,
-  "version": "1.2.3",
-  "rid": "win-x64",
-  "archiveSha256": "<64 hex characters>",
-  "archiveSize": 123,
-  "files": [
-    { "path": "AcDream.App.exe", "sha256": "<64 hex characters>", "size": 123, "unixMode": 0 }
-  ]
-}
-```
-
-Paths use `/`, are relative, normalized, unique under ordinal-ignore-case,
-and sorted ordinally. `unixMode` contains only the portable permission bits
-captured from the ZIP entry. Startup verifies every recorded regular file by
-size/SHA, rejects unrecorded files/reparse points, and requires the two host
-executables before admitting a version. Extraction uses a random sibling
-directory under `DataDirectory/app/`; promotion to `<version>/` is one
-same-volume directory rename.
-
-`DataDirectory/app/current.json` is the only activation authority:
-
-```json
-{ "schemaVersion": 1, "currentVersion": "1.2.3", "previousVersion": "1.1.0" }
-```
-
-`previousVersion` is omitted for the first activation. Pointer writes are
-write-through temporary-file + same-directory atomic rename. The last valid
-pointer is also atomically preserved as `current.previous.json`; startup may
-restore that exact backup only when `current.json` is missing/malformed and
-the referenced version verifies. Orphan LA10 staging directories, download
-archives, corrupt-version quarantine directories, and pointer temporaries are
-transaction-owned by exact lowercase GUID names and are removed only under the
-exclusive update lease; near-matching user names are preserved. A corrupt
-installed version is never silently selected; the explicit one-step rollback
-swaps the two verified pointer versions.
-
-`DataDirectory/app/.update-session.lock` is the cross-process barrier. Each
-supervised launcher activity holds a shared OS handle from before executable
-resolution until terminal process observation; launcher disposal requests
-child termination and does not release that handle until the child is actually
-observed terminal. An update/rollback holds the
-exclusive handle for its entire recovery/download/extract/promote/pointer
-transaction. Failure to acquire the exclusive handle is an immediate refusal,
-not a wait behind a running session. The open handle, not lock-file contents,
-owns the lease and therefore releases after process death.
-
-Launcher self-update staging lives at
-`DataDirectory/launcher-update/transactions/<transactionId>/` and the sole
-durable authority is `DataDirectory/launcher-update/pending.json` (schema 3):
-
-```json
-{
-  "schemaVersion": 3,
-  "transactionId": "0123456789abcdef0123456789abcdef",
-  "state": "staged",
-  "version": "1.2.3",
-  "rid": "win-x64",
-  "targetDirectory": "<absolute current launcher directory>",
-  "archiveSha256": "<64 hex characters>",
-  "archiveSize": 123,
-  "files": [
-    { "path": "acdream-launcher.exe", "sha256": "<64 hex characters>", "size": 123, "unixMode": 0 }
-  ],
-  "apply": null
-}
-```
-
-Before mutation the verified staged launcher becomes the next-start helper and
-waits for the initiating launcher PID without invoking a shell. It first copies
-the complete verified payload into the target-local
-`.acdream-self-update-<transactionId>/incoming/` tree. The plan then advances
-to `applying`; `apply` is an ordinally sorted union of new payload paths, the
-owned metadata path, and obsolete paths from the previous ownership record:
-
-```json
-[
-  {
-    "path": "acdream-launcher.exe",
-    "operation": "install",
-    "hadOriginal": true,
-    "priorSha256": "<64 hex characters>",
-    "priorSize": 123,
-    "priorUnixMode": 0,
-    "replacementSha256": "<64 hex characters>",
-    "replacementSize": 456,
-    "replacementUnixMode": 0
-  },
-  {
-    "path": "new-support.dat",
-    "operation": "install",
-    "hadOriginal": false,
-    "priorSha256": null,
-    "priorSize": null,
-    "priorUnixMode": null,
-    "replacementSha256": "<64 hex characters>",
-    "replacementSize": 456,
-    "replacementUnixMode": 0
-  }
-]
-```
-
-Every `hadOriginal` entry persists the exact pre-mutation SHA-256, length, and
-Linux mode bits; a no-original entry has all three prior fields null. Every
-install entry likewise persists the verified replacement metadata, while a
-remove entry has all three replacement fields null. The journal is invalid
-unless those fields agree with `hadOriginal` and `operation`.
-
-Existing targets are replaced with one same-filesystem atomic replace whose
-backup is also target-local. Previously absent noncanonical files use one
-same-filesystem rename; obsolete owned files use one rename into backup. The
-canonical launcher path therefore contains either the complete old file or the
-complete new file at every durable crash boundary. Rollback first performs a
-zero-mutation preflight of the complete target-local transaction and every
-journal entry. It rejects reparse points, unsafe parents, unrecorded paths,
-ambiguous file layouts, and any SHA-256/length/mode mismatch in a prior,
-incoming, or discard file. Only a fully preflighted rollback may atomically
-restore backups; newly created files move to target-local discard rather than
-being deleted. The complete prior target set is then reverified before the
-plan enters durable `rolledBack` state while retaining the journal. Retry is
-allowed only after that prior set is reverified again and the plan returns to
-`staged`. Thus rollback is atomic per file and idempotent after a process/power
-loss. Any ambiguity preserves the applying plan and transaction evidence and
-forbids launching the canonical path for manual recovery. Linux mode bits come
-from the verified incoming file. A helper that cannot immediately
-acquire the exclusive update lease defers the staged plan and exits without
-restarting the old launcher, preventing restart loops.
-
-Successful application writes strict target ownership metadata at
-`<launcher directory>/launcher.install.json`:
-
-```json
-{
-  "schemaVersion": 1,
-  "version": "1.2.3",
-  "rid": "win-x64",
-  "files": [
-    { "path": "acdream-launcher.exe", "sha256": "<64 hex characters>", "size": 123, "unixMode": 0 }
-  ]
-}
-```
-
-The archive may not supply that reserved metadata path. A prior valid record is
-the only authority for obsolete-file removal; the first managed update does
-not infer ownership of unrelated legacy files. On success the plan becomes
-`awaitingConfirmation`; the new launcher confirms at its first managed
-instruction, after which the helper releases its lease and the confirmed
-launcher reclaims plan, data-transaction, and target-local residue. An
-`applying` plan is rolled back before retry, and failure to start/confirm the
-new launcher restores every original (and removes every no-original target).
-The helper restarts the restored canonical launcher only after a fresh complete
-verification of the retained `rolledBack` journal; rollback corruption or an
-unsafe backup/discard tree exits without starting either launcher.
-Reading `pending.json` never performs cleanup. Ordinary startup attempts the
-exclusive lease without waiting and skips update cleanup entirely when another
-session/staging transaction owns it. All plan paths are re-derived/contained
-under pinned roots; the target directory must equal the actual launcher base
-directory.
-
-Every portable archive and persisted relative path rejects Windows device
-segments on every host: `CON`, `PRN`, `AUX`, `NUL`, `CLOCK$`, `CONIN$`,
-`CONOUT$`, `COM1`-`COM9`, `LPT1`-`LPT9`, and the Windows-equivalent superscript
-forms `COM¹`/`COM²`/`COM³` and `LPT¹`/`LPT²`/`LPT³`, including extensions.

-
-## Review protocol
-
-Per slice: implementer commit(s) → Opus dual-lens review (architectural +
-retail-where-applicable) → fix round → narrow re-review of fixes → slice DONE
-in ledger. Reviews name blast radius explicitly
-(`claude-memory/feedback_blast_radius_single_lens.md`). Slices LA7/LA8 add the
-retail-fidelity lens against named-retail symbols cited in the slice body;
-LA6 adds CH-regression scrutiny; LA0 adds guard-integrity scrutiny.
-
-## Gate round 1 — 2026-08-15 (first live launch by the user)
-
-The user's first hands-on launch found the launcher exiting on every click.
-Root cause (`d54b8a78`): `MainWindow`'s constructor called
-`AvaloniaXamlLoader.Load(this)` instead of the generated
-`InitializeComponent()`, so every `x:Name` backing field was null and any
-modal open/close threw out of the dispatcher into `Program`'s exit-74
-guard. It reached the gate because NO test constructed `MainWindow` —
-filed and closed as **#399** (`2b439cc1`, merged): `Avalonia.Headless.XUnit`
-view tests with falsification evidence (12/12 fail against the old code,
-12/12 pass against the fix; launcher suite 66/66 Windows + native Ubuntu;
-xunit→xunit.v3 in that test project). Same round (`e1e94697`): **#398**
-closed — fatal exceptions now write a full-stack crash report under the
-data root (isolated-roots-safe; the first cut leaked to the real data root
-when parsing failed, caught live and fixed) — and `acdream-bake.exe` is now
-co-deployed on plain Build, not just Publish, so a developer-built launcher
-can actually run its first-run wizard (79.6 MB single file beside the
-launcher, incremental, `--help` verified). One transient 65/66 on the first
-post-merge test run did not reproduce across a clean rebuild + six repeats —
-consistent with stale-artifact mixing, but if it EVER recurs, capture the
-failing test name before anything else. Merged slice worktrees/branches
-(la2/la3/la7a/la-uitest) removed. Opus batch review: PASS (HIGH
-confidence) with 6 findings, all landed same-day: F1 the crash reporter's
-by-construction claim was FALSE (the launcher holds passwords in three
-fields; the true invariant — no throw site interpolates a credential
-value — is now pinned by a forced-failure test), F2 the co-deploy's
-Inputs covered only Bake's own sources, not its Content/Platform/Core/
-Plugin.Abstractions closure (the stale-artifact class again; fixing it
-exposed and fixed two more incrementality traps: SkipUnchangedFiles
-leaving outputs older than inputs, and %(Item.Metadata) in a plain
-Include not batching — a literal '%(...)' input is permanently
-out-of-date), F3 dual bake publish on RID publishes (guarded by
-_IsPublishing; verified 0 build-target co-deploys during a real publish),
-F4 misattributed comment, F5 template-scoped x:Name false-fail (sweep now
-walks the XML with template-ancestor tolerance), F6 dead using, plus the
-optional Path.IsPathFullyQualified hardening on the crash reporter's
--data-dir fallback. Launcher 67/67, Launcher.Core 317/317. The §A–I
-connected script remains the open user gate.
-
-## Gate round 2 — 2026-08-15 (first live launcher→client flow) — char-select matrix USER-PASSED
-
-**USER-PASSED 2026-08-15 (end of round):** the character-select visual/
-interaction matrix — stretched-canvas look with bilinear filtering,
-aligned widgets, left-justified roster, World box reading the live server
-name ("sawato"), and the centered exit confirmation — all accepted on the
-live launcher→client flow. Round-2 commits after the round-1 batch:
-`6e1c0967` (session-config launches force the retail UI), `9ce72925`
-(PFID_CUSTOM_RAW_JPEG decode + resolution guards), `73041d70`
-(whole-canvas AD-98 scale + inverse input), `308f40a3` (linear-twin
-bilinear stretch), `ef96c554` (exit confirmation + authored justify +
-world name, AD-99), `2e6d69dd` (#400), `0a7dc7d6` (durable world-name
-read + canvas-centered dialogs). Remaining before shipment: the formal
-§A–I script rows (probe ×2, headless+plugins+login commands, delete/
-restore, A→B update swap, row I Linux), and the final-HEAD preflight
-re-run.
-
-**Round REVIEW-CLOSED 2026-08-15:** the owed Opus dual-lens batch review
-of the six round-2 commits returned PASS with 8 findings; the fix round
-(`0baebce2` — headline: `RetailWaitDialogView` was the ONE dialog view the
-EffectiveCanvasSize sweep missed, firing on ENTER; plus the two stale
-deleted-mechanism doc assertions, the Confirmation `0xAC` property,
-truncating input mapping, the IsCurrent world-name gate, the AD-98
-evidence note) closed all seven in the narrow re-review; F2 filed as
-#401 (invert RetailUi to opt-out). The review also proved the
-`DatWidgetFactory` justify widening has ZERO regressions across all 35
-layout fixtures (303 buttons swept; the 16 authored-Left all already
-left-aligned via their face-child branch) and is a move TOWARD retail
-(`CalcJustification @0x00467260` has no lifted-from-child condition).
-
-Two real defects, both root-caused and fixed:
-
-1. **`6e1c0967` — launcher-spawned clients had NO interface at all.**
-   `RetailUi` rode the dev env var `ACDREAM_RETAIL_UI`; `FromSessionConfig`
-   inherited the env parse; the launcher strips `ACDREAM_*` from children
-   (LA11 isolation). Product launches therefore got the dev default: world
-   rendering, zero UI — character screen included. Session-config launches
-   now force `RetailUi = true` (a session-config launch IS a product
-   launch); the env flag remains the dev-launch opt-in. Test-pinned with a
-   null env.
-2. **`9ce72925` — character-select screen rendered magenta background/
-   fills.** The screen's 800×600 root background (`0x06007576`) is
-   `PFID_CUSTOM_RAW_JPEG` — a complete JFIF stream retail hands to the
-   Intel JPEG Library (`RenderSurface::CreateFromSourceData @0x004440a0`),
-   with Width/Height legitimately 0 on disk. `SurfaceDecoder` had no JPEG
-   case AND a non-positive-dimension guard, so it fell silently to the
-   magenta placeholder; the listbox/ENTER fills are transparent, so one
-   broken background bled through as three symptoms. Fixed via
-   StbImageSharp (managed, Linux-safe; codec-library substitution per the
-   BCnEncoder precedent — no register row). BOTH silent traps now log once
-   per id (id-resolves-but-undecodable in `SurfaceDecoder`;
-   id-missing-from-DATs in `TextureCache`) — the existing magenta guard
-   only covered id-0. New installed-DAT sweep asserts every char-select
-   media id decodes non-magenta. Full suite 14,034 green.
-
-Session-orchestration facts this round: the machine gained PowerShell 7
-(winget, user-approved — the LA fixture tooling hard-requires it); an
-orphan feed server from the earlier session held port 43119 with stale
-fixture data (stopped); the launcher self-update bootstrap restart on a
-dev binary is EXPECTED (staged launcher update → exit → respawn).
-Observations still open for this round: the duplicated "versioned client
-is unavailable" status line (cosmetic), and verifying Create Character is
-disabled on the live screen.

-# Release stabilization and human-maintainability campaign
-
-**Status:** PROPOSED — plan recorded; implementation not started  
-**Created:** 2026-08-18  
-**Audit baseline:** `15539a22a67f8d915d88f8b1d8126cd55eedda6e`  
-**Evidence:** [`../reviews/2026-08-17-release-maintainability-audit.md`](../reviews/2026-08-17-release-maintainability-audit.md)  
-**Findings:** [`../reviews/findings-ledger.md`](../reviews/findings-ledger.md)  
-**Coverage proof:** [`../reviews/coverage-ledger.md`](../reviews/coverage-ledger.md)
-
-## 1. Goal
-
-Prepare acdream for a responsible public release and for maintenance by human
-developers who do not have access to prior AI conversations, private worktrees,
-or campaign memory.
-
-The campaign succeeds when a new maintainer can clone the repository, identify
-the current architecture and supported release, reproduce the build and test
-gate, understand why non-obvious retail behavior exists, and publish or roll
-back an authenticated release using repository-owned instructions.
-
-This is a stabilization program, not a rewrite. The existing Runtime/App/
-Headless architecture remains the foundation unless a slice proves a specific
-boundary is wrong.
-
-## 2. Binding principles
-
-1. **Protect behavior before cleanup.** Establish a deterministic complete gate
-   before broad refactors, comment cleanup, or file decomposition.
-2. **Distill knowledge; do not erase it.** No note, comment, issue history,
-   diagnostic, capture, or raw artifact is removed until its durable value has
-   a verified destination.
-3. **One current truth.** Stable architecture and release state must not depend
-   on choosing between README, roadmap, milestone, campaign, memory, or
-   tool-specific instruction copies.
-4. **Separate evidence from contracts.** Source comments explain the current
-   invariant. Dated research records preserve investigation history. Raw
-   captures live in an explicit artifact tier.
-5. **No count-only gates.** A test total is meaningful only when the report says
-   which hermetic, installed-DAT, live, visual, manual, and diagnostic lanes
-   actually ran.
-6. **Bound every external interaction.** Process waits, network operations,
-   test runs, and release steps require timeouts, cancellation, and diagnostic
-   artifacts on failure.
-7. **Small reversible slices.** Each slice gets focused tests, a complete gate,
-   a reviewable commit, a rollback description, and a plan-ledger update.
-8. **No opportunistic feature work.** New gameplay features wait unless needed
-   to prove or repair a release blocker.
-
-## 3. Knowledge-preservation protocol
-
-Every cleanup candidate is classified before it moves:
-
-| Class | Durable value | Destination |
-|---|---|---|
-| Current invariant | Required behavior, ordering, ownership, threading, or retail rule | Short source comment and/or maintained architecture contract |
-| Decision rationale | Alternatives considered, failed attempts, tradeoffs, gate outcome | Dated decision/research record linked from the current contract |
-| Reproducible evidence | Minimal fixture, retail symbol/address, script, checksum, expected result | Versioned fixture/research record in Git |
-| Raw evidence | Large logs, captures, Ghidra state, screenshots, dumps | Approved versioned artifact store with manifest, hash, provenance, and retention policy |
-| Superseded or incorrect claim | Historically useful but no longer operative | Marked `SUPERSEDED` with successor link; archive after references are migrated |
-| Duplication/noise | Repeats a preserved fact and adds no independent evidence | Delete only after destination/link validation |
-
-Before deleting or rewriting historical material, all of these must be true:
-
- its current invariant is recorded at the owning code or architecture seam;
- useful retail provenance, failed approaches, and acceptance evidence remain
-  searchable under stable identifiers;
- inbound links and source comments point at the surviving destination;
- any raw artifact has an approved distribution, privacy, and licensing status;
- the replacement was reviewed by someone other than its author;
- the complete gate passes after the move.
-
-Git history alone is not the preservation mechanism. History may later be
-rewritten to remove large or legally restricted artifacts.

-R4 starts in parallel because it requires owner/legal decisions. It blocks a
-public release but does not block the technical safety work in R1–R3.
-
-## 5. Slice map
-
-| Slice | Outcome | Depends on | Release blocking |
-|---|---|---|---|
-| R0 | Baseline and durable campaign authority accepted | — | yes |
-| R1 | Launcher shutdown lock inversion fixed and deterministic | R0 | yes |
-| R2 | Pinned clean build and complete bounded CI gate | R1 | yes |
-| R3 | Test results truthfully distinguish executed, skipped, and diagnostic work | R2 | yes |
-| R4 | Licence, provenance, credential disclosure, and release ownership decided | R0; parallel | yes |
-| R5 | One current documentation authority; public docs match the product | R2–R3 | yes |
-| R6 | Dead presentation/backend/probe surfaces removed; supported tools reproducible | R3–R5 | normally yes |
-| R7 | Plugin compatibility/lifetime and diagnostic configuration hardened | R3 | yes for advertised plugin release |
-| R8 | Highest-risk giant owners decomposed only at proven seams | R3, R6–R7 | selective |
-| R9 | Large/generated research artifacts moved under an approved policy | R4 | yes if repository is distributed |
-| R10 | Clean-clone release candidate and rollback rehearsal | all blocking slices | yes |
-
-## 6. R0 — Baseline and authority
-
-### Work
-
- Review and accept this plan and the six documents under `docs/reviews/`.
- Record the exact starting commit, SDK, package sources, operating systems,
-  supported release platforms, and current external prerequisites.
- Decide who owns legal/provenance decisions, CI/release credentials, and final
-  release approval.
- Pause unrelated feature campaigns until R1–R3 establish the safety net.
- Preserve the audit baseline before any cleanup; do not rewrite artifact
-  history in this slice.
-
-### Exit criteria
-
- Plan and audit artifacts are tracked in the repository.
- One named owner exists for technical release approval and one for
-  licensing/provenance approval; the same person may hold both roles.
- The ledger in §17 identifies R1 as the only active implementation slice.
-
-## 7. R1 — Fix the launcher shutdown deadlock first
-
-### Confirmed failure
-
-`LauncherProcessSupervisor.Dispose` currently holds the supervisor `_gate`
-while disposing a child. `WindowsSystemChildProcess.Dispose` enters
-`System.Diagnostics.Process.Dispose`; concurrently, the process-exit callback
-can enter `OnProcessExited` and try to publish state through the same supervisor
-gate. The captured wait cycle is:
-
-```text
-shutdown: supervisor _gate -> Process internals
-exit callback: Process internals -> supervisor _gate
-```
-
-The complete solution test process hangs on
-`ANullStderrLogPathBehavesExactlyAsBeforeForBothChildProcessKinds`; the
-Launcher.Core project can pass alone because the race timing changes.
-
-### Design constraints
-
- Never call child/process operations that may wait, dispose, raise callbacks,
-  or execute external code while holding `_gate`.
- Under `_gate`, make only the minimal state transition and snapshot the exact
-  children/work to retire.
- Perform unsubscribe, stop, kill, wait, and dispose work outside `_gate`.
- Exit callback and explicit disposal must converge idempotently regardless of
-  which arrives first.
- Preserve exact terminal-state ordering, status publication, graceful-stop
-  behavior, and child ownership; do not solve the hang by dropping callbacks.
- A failed cleanup must remain observable without starving later cleanup.
-
-### Required tests
-
- Add a barrier-controlled race test that deterministically pauses the child
-  exit callback while disposal begins. Do not use `Thread.Sleep` as the oracle.
- Cover exit-before-dispose, dispose-before-exit, simultaneous exit/dispose,
-  repeated dispose, stop timeout/kill fallback, and callback failure.
- Assert one terminal publication, no resurrection, no orphan child, no held
-  supervisor lock during process disposal, and bounded completion.
- Run the focused race test repeatedly after its deterministic single pass.
- Run all Launcher.Core tests.
- Run the complete Release solution twice in fresh processes under a documented
-  timeout and retain hang dumps if either run fails to terminate.
-
-### Exit criteria
-
- No process/child disposal occurs under the supervisor gate.
- The deterministic race test fails against the baseline mechanism and passes
-  against the fix.
- Two complete bounded solution runs finish with zero failures.
- F-009 and T-001 receive exact fix commit and gate evidence.
-
-## 8. R2 — Reproducible build and complete CI gate
-
-### Work
-
- Pin the accepted .NET 10 SDK feature band in `global.json`.
- Centralize common compiler/analyzer settings and package versions; enable
-  locked restore for release/CI.
- Eliminate all 26 clean-rebuild test warnings or make a narrowly justified,
-  centrally documented exception fail-safe.
- Build every supported product and every supported tool from a clean checkout.
- Make CI run the complete solution, not only portability subsets. Give each
-  project/process a timeout and collect test logs plus managed dumps on hangs.
- Preserve focused Windows/Linux portability lanes, but do not represent them
-  as the complete gate.
- Record restore sources, SDK/runtime, RID, commit, executed/skipped counts, and
-  artifact hashes in every release report.
-
-### Exit criteria
-
- A clean clone restores and builds with the pinned toolchain and no warnings.
- Complete CI runs every default release test project and fails on timeout.
- The launcher hang cannot silently consume the CI job indefinitely.
- Package resolution and the gate command are reproducible from repository
-  instructions alone.
-
-## 9. R3 — Make test reporting truthful
-
-### Required lanes
-
-1. **Hermetic release lane:** default CI; unavailable local data is never a
-   silent passing return.
-2. **Installed-DAT/prepared-package lane:** explicit prerequisites and per-suite
-   skip identity; result published separately.
-3. **Live/connected/visual/listening lane:** operator-owned, dated evidence;
-   never counted as ordinary unit coverage.
-4. **Diagnostic/manual lane:** probes, dumps, fixture generators, and
-   characterization programs invoked explicitly outside default test totals.
-
-### Work
-
- Replace the 271 asset/environment empty-return tests with explicit lane
-  requirements, truthful skips, or hermetic fixtures.
- Move or give stable assertions to the 51 output-only diagnostic methods.
- Delete/replace the three confirmed useless entire cases and the tautological
-  assertions catalogued in the audit.
- Remove the duplicate theory row and make the clean rebuild warning-free.
- Remove or re-home at least 52 tests with the unreachable panel stack.
- Retire temporary source-shape freezes once a semantic architecture/behavior
-  guard exists; retain whole-tree dependency guards that express real rules.
- Assign and stabilize the seven documented load-sensitive tests. Do not hide
-  them with generic retries.
- Inject controllable time into double-click and real-time transport tests.
-
-### Exit criteria
-
- Default test success means every discovered default contract executed.
- Reports give exact reasons and prerequisite identity for every skip.
- Diagnostics and manual generators do not inflate release regression totals.
- No known duplicate row, literal tautology, or permanent empty scaffold remains
-  in the default suite.
-
-## 10. R4 — Licence, provenance, security, and release ownership
-
-This slice requires explicit project-owner decisions and, where appropriate,
-qualified legal review. The implementation agent records evidence but does not
-invent a redistribution basis.
-
-### Work
-
- Select the project licence and establish contributor/code ownership.
- Audit WorldBuilder-derived code, dependency notices, named-retail/decompiler
-  exports, PDB-derived data, Ghidra databases, captures, images, and DAT-derived
-  fixtures for provenance and redistribution status.
- Decide which research artifacts may be public, private, regenerated, or
-  deleted from distributable history.
- Add SECURITY, CONTRIBUTING, changelog/version authority, disclosure and
-  deletion behavior for plaintext launcher credentials, and a vulnerability
-  response path.
- Define release artifact contents, supported platforms, SBOM/provenance,
-  signing/attestation policy, checksums, update manifest generation, rollback,
-  and release approval.
-
-### Exit criteria
-
- Publicly distributed source and artifacts have an approved licence and
-  complete notices/provenance inventory.
- Users are told exactly how credentials are stored and removed.
- The launcher updater's production manifest and archives are generated and
-  verified by a repository-owned release process.
-
-## 11. R5 — One current documentation authority
-
-### Work
-
- Correct public README claims to the actual Vulkan-only client and retained UI.
- Make `docs/README.md` stable navigation plus a generated current-status block
-  sourced from one structured milestone/release ledger.
- Keep architecture documents limited to durable boundaries, ownership,
-  threading/lifetime, and data flow. Move commit/test-count/rollback chronology
-  to dated closeout records.
- Replace duplicated `AGENTS.md`/`CLAUDE.md` product truth with one maintained
-  tool-neutral source and generated thin adapters; fail CI on drift.
- Mark every memory/plan/spec as current, active, superseded, or historical.
- Normalize active issue/divergence indexes and validate their IDs, statuses,
-  paths, and links mechanically.
- Apply the knowledge-preservation protocol before shortening any campaign or
-  issue record.
-
-### Exit criteria
-
- A new maintainer receives the same current answer from README, documentation
-  map, architecture, milestone/status ledger, and agent instructions.
- No current authority links missing private `claude-memory`, absent skills, or
-  developer-local paths.
- Historical records remain searchable but cannot override current truth.
-
-## 12. R6 — Dead surfaces, diagnostics, and tools
-
-### Work
-
- Decide and then remove or explicitly support the unreachable
-  `IPanelRenderer`/old panel stack and its tests.
- Remove stale OpenGL/framebuffer/ImGui apparatus and failed temporary-cleanup
-  markers from shipping assemblies after preserving useful evidence.
- Stop including the smoke plugin in release output by default.
- Classify every tool/script as supported, diagnostic, research-only, or
-  archived. Repair the five broken C# tools chosen as supported; remove
-  developer-home/old-worktree paths and document exact prerequisites.
- Centralize environment/diagnostic configuration at composition roots.
-
-### Exit criteria
-
- Shipping assemblies and package contents contain no abandoned presentation
-  backend or sample plugin by accident.
- Every supported tool builds from the pinned clean checkout.
- Research-only tools are clearly invoked outside the release build.
-
-## 13. R7 — Plugin and configuration contracts
-
-### Work
-
- Enforce supported plugin API versions before loading code.
- Implement manifest dependencies or remove the unsupported promise.
- Publish/version `AcDream.Plugin.Abstractions` if plugins are advertised.
- Report registration cleanup and callback failures without preventing
-  best-effort teardown; prove collectible load-context release under failures.
- Replace absent/null allow-list ambiguity with one explicit production default.
- Replace direct hot-path environment reads/process-static mutable diagnostics
-  with immutable session-scoped configuration and typed sinks.
-
-### Exit criteria
-
- An incompatible plugin fails before activation with an actionable message.
- Disable/dispose reports all cleanup failures and cannot silently retain host
-  registrations.
- Graphical and headless hosts have the same documented plugin/config default.
-
-## 14. R8 — Bounded structural decomposition
-
-This slice begins only after R1–R3. File size alone does not authorize a split.
-
-### Priority candidates
-
- `RuntimeSetPositionState`
- `TransitionTypes`
- `RetailUiRuntime`
- `LiveEntityRuntime`
- `WorldSession`
- `WbDrawDispatcher`
-
-### Rules
-
- Identify one ownership/lifetime or pure-algorithm seam at a time.
- Preserve a single state owner; do not replace a large class with mirrored
-  mutable state or a service graph of aliases.
- Prefer partial-file navigation when a state machine must remain one owner.
- Establish behavior/sabotage tests before extraction and remove corresponding
-  temporary source-text freezes afterward.
- Replace Chorizite/GL vocabulary in prepared-content DTOs with versioned
-  acdream-owned semantics at a separately reviewed boundary.
-
-### Exit criteria
-
- Each extraction reduces change coupling or improves ownership clarity; line
-  count reduction alone is not success.
- Runtime behavior, retail evidence, allocations, and teardown ledgers remain
-  equivalent under the relevant focused and complete gates.
-
-## 15. R9 — Repository artifact migration
-
-### Work
-
- Inventory the approximately 575 MiB of Ghidra state, 299 MiB research tree,
-  and 151 MiB tracked logs by provenance, sensitivity, reproducibility, and
-  ongoing value.
- Keep compact fixtures, scripts, tool versions, summaries, and checksums in
-  Git. Move approved raw bundles to a versioned artifact store.
- Add a manifest/bootstrap command that verifies artifact identity.
- Define retention, redaction, access, and backup policy.
- Treat Git-history rewriting as a separately approved migration with backup,
-  contributor coordination, remote replacement, and verification. Never do it
-  as an incidental cleanup command.
-
-### Exit criteria
-
- A normal clone contains what build/test/maintenance requires without opaque
-  generated databases or raw logs.
- Authorized researchers can retrieve exact approved evidence by manifest and
-  hash.
- Restricted or non-redistributable material is absent from public history.
-
-## 16. R10 — Release-candidate gate
-
-From a fresh clone on every supported release platform:
-
- restore with the pinned, locked toolchain;
- build every shipped product and supported tool with zero warnings;
- run the complete hermetic test lane with no failures, silent no-ops, hangs,
-  or generic retries;
- run and report the applicable DAT, connected, visual/listening, updater,
-  installer, graceful-shutdown, and rollback gates;
- generate versioned per-RID packages, plugin abstraction package if supported,
-  SBOM/provenance/checksums, and updater manifest;
- install/update/rollback using only public release instructions;
- verify package contents contain no credentials, developer paths, smoke
-  plugin, raw probes, or unapproved research artifacts;
- obtain technical and licensing/provenance approval.
-
-Public release remains **NO-GO** until every blocking slice is closed.
-
-## 17. Cross-session execution ledger

-### R1 implementation checkpoint — 2026-08-18
-
-**Working-tree base:** `15539a22a67f8d915d88f8b1d8126cd55eedda6e`  
-**Commit:** `0a934cf5` on `codex/release-stabilization`; the checkpoint is
-durable on that campaign branch but is not yet merged to `main`.
-
-Implementation:
-
- `LauncherProcessSupervisor.Dispose` now transfers `_process` ownership to a
-  local and clears the field under `_gate`, then performs stop, event removal,
-  and child disposal outside the gate.
- Public `Stop` and disposal share one `StopProcess` implementation, preserving
-  graceful-stop, close-window, timeout, kill, and post-kill observation order.
- `OnProcessExited` reads the event sender's optional exit code without holding
-  `_gate`, then commits the terminal transition through the existing ordered
-  state publisher. A callback already captured during teardown may therefore
-  finish instead of forming the supervisor/Process lock cycle.
- `DisposeAllowsAnAlreadyCapturedExitCallbackToComplete` uses explicit barriers:
-  the fake captures the exit delegate before unsubscription; its disposal
-  releases the callback and waits for it to return. There are no timing sleeps
-  in the oracle, and an emergency release keeps failure against the old code
-  bounded rather than wedging the test host.
-
-Sabotage and focused evidence:
-
- With the old lock shape temporarily restored and the new test retained, the
-  test failed with its expected five-second timeout. The fake's cleanup barrier
-  then released the old cycle, so the test process exited normally.
- With the fix restored, the same test passed in 21 ms.
- The race test passed 25/25 times in fresh `dotnet test` processes.
- All `LauncherProcessSupervisorTests` passed: 22/22.
- Complete Launcher.Core passed under a 180-second hard process bound:
-  339 passed / 0 skipped / 0 failed in 52 seconds.
-
-Complete-solution evidence:
-
- Release build completed inside a 300-second bound with 0 warnings / 0 errors
-  in the evaluated incremental build.
- The exact serialized command was
-  `dotnet test AcDream.slnx -c Release --no-build --no-restore --nologo -m:1`,
-  launched in a fresh child process for each run. An outer process watchdog
-  allowed 900 seconds, killed the complete process tree on expiry, and treated
-  timeout as failure.
- Run 1: 12 assemblies, 14,748 passed / 77 skipped / 0 failed, 1:28.822,
-  bounded exit code 0.
- Run 2: 12 assemblies, 14,748 passed / 77 skipped / 0 failed, 1:30.241,
-  bounded exit code 0.
-
-Adjacent evidence, deliberately not folded into R1:
-
- One default-parallel whole-solution run terminated normally in 58.148
-  seconds—important negative evidence for the former hang—but failed one
-  `AcDream.Launcher.Tests` Avalonia headless cleanup because a compositor was
-  accessed from a non-owning thread. The Launcher test project then passed
-  67/67 alone. R1 makes no Avalonia changes; R2/R3 must decide the supported CI
-  scheduling and ownership of that pre-existing parallel-run failure.
- The known duplicate Core theory row and 77 skip classifications remain
-  unchanged and belong to R3. R1 does not use their headline count as proof of
-  test quality.
-
-Changed implementation/test files:
-
- `src/AcDream.Launcher.Core/Launching/LauncherProcessSupervisor.cs`
- `tests/AcDream.Launcher.Core.Tests/Launching/LauncherProcessSupervisorTests.cs`
-
-Rollback is `git revert 0a934cf5`; do not rewrite branch history.
-
-### R2 complete-gate checkpoint — 2026-08-18
-
-**Working-tree base:** `0a934cf5781c003375c14af9a1f565254df0f9f9`
-**Commit:** `2ac05486` on `codex/release-stabilization`; the checkpoint is
-durable on that campaign branch but is not yet merged to `main`.
-
-Implemented gate:
-
- `global.json` pins the accepted .NET 10 SDK feature band at `10.0.300` with
-  `latestPatch` roll-forward and prerelease SDKs disabled. Every existing
-  `actions/setup-dotnet` step now reads that file instead of floating on
-  `10.0.x`.
- `tools/run-release-gate.ps1` discovers every project under `tests/` that
-  declares `Microsoft.NET.Test.Sdk` or `IsTestProject`, verifies the project is
-  present in `AcDream.slnx`, restores/builds the solution, and runs each test
-  assembly exactly once in its own Release process. It does not retry.
- Restore, build, and each test process have 600/900/600-second outer bounds.
-  Tests additionally use VSTest's 180-second per-test blame-hang collector with
-  mini dumps. An outer timeout kills the complete process tree and reports exit
-  code 124; GitHub Actions adds a 45-minute job bound.
- Every run writes exact commands and output, one TRX per assembly, any blame
-  sequence/dumps, `dotnet --info`, configured NuGet sources, commit/branch/RID,
-  aggregate executed/passed/skipped/failed counts, and `SHA256SUMS.txt`.
- `.github/workflows/release-gate.yml` runs the gate on pull requests, pushes
-  to `main`, and manual dispatch on `windows-latest`, then uploads the evidence
-  even when the gate fails. The focused Windows/Linux portability and Vulkan
-  lanes remain separate and are no longer the only deterministic CI coverage.
- `docs/release-gate.md` is the repository-owned local/CI runbook.
-
-Test-isolation corrections, with no product behavior change:
-
- Four `MainWindowViewTests` that call `Show()` now close their window and pump
-  dispatcher cleanup in `finally` on the owning Avalonia test session. The old
-  tests leaked shown, thread-affine compositor state to runner teardown; no
-  suite serialization or retry was added.
- The complete gate's first evidence run correctly failed
-  `RealChildStderrIsCapturedForTheProcessStartInfoPath`: its live polling helper
-  briefly denied write sharing, so the final async stderr callback observed an
-  `IOException` and the deliberately no-throw capture sink latched off. The
-  helper now reads with `FileShare.ReadWrite | FileShare.Delete`, matching the
-  production status tailer; its assertions and five-second bound are unchanged.
-
-Verification:
-
- Focused `MainWindowViewTests`: 13 passed / 0 skipped / 0 failed.
- Three fresh default-parallel whole-solution runs completed inside independent
-  180-second process bounds with 12/12 TRX files and no Avalonia cleanup error:
-  56.719, 56.321, and 58.506 seconds. Each reported 14,748 passed / 77 skipped /
-  0 failed.
- The stderr ProcessStartInfo test passed 25/25 fresh-process repetitions after
-  the live-reader correction.
- The actual outer-watchdog function killed a controlled fixture process tree
-  at 2.107 seconds, returned 124, and left no child process.
- The repository command `pwsh ./tools/run-release-gate.ps1` completed in
-  107.337 seconds on SDK `10.0.300`, RID `win-x64`: 12 assemblies, 14,748
-  executed and passed / 77 skipped / 0 failed. The evidence manifest contains
-  28 verified SHA-256 entries.
-
-Deliberately still open in the wider R2 slice:
-
- the 26 warnings observed by a clean recompilation, centralized compiler and
-  package settings, package lock files/locked restore, and broken or unsupported
-  tool-project decisions;
- the known duplicate Core theory row and classification of the 77 skips, which
-  remain R3 work; and
- stale public headline counts, which must be corrected with the documentation
-  authority work rather than hand-edited as part of this gate checkpoint.
-
-Therefore this checkpoint closes F-014 on the campaign branch and the SDK part
-of F-019, and gives F-010 a truthful machine-readable count. It does not claim
-the broader R2 reproducibility slice or R3 test-quality cleanup is complete.
-
-Rollback is `git revert 2ac05486`; do not rewrite branch history.
-
-### R2 reproducibility closeout — 2026-08-18
-
-**Working-tree base:** `b459e0cf0cab9241b0771d2ce6838083f2c84162`
-
-**Implementation commit:** `c38f6b88522750abc2e4acf1898ed566c5576e4a`
-on `codex/release-stabilization`; the closeout is durable on that campaign
-branch but is not yet merged to `main`.
-
-Repository policy and dependency graph:
-
- `Directory.Build.props` is the common .NET 10, language, nullable, latest
-  analysis, warnings-as-errors, deterministic-build, and lock-file authority.
- `Directory.Packages.props` centrally pins all 30 direct package versions.
-  All 89 `PackageReference` sites are versionless; no project-local version can
-  silently drift.
- `NuGet.Config` clears machine fallback folders and package sources, then
-  declares only `nuget.org`.
- Every supported project owns `packages.neutral.lock.json` (44 files). Every
-  shippable source project additionally owns `packages.win-x64.lock.json` and
-  `packages.linux-x64.lock.json` (14 of each; 72 graphs total). Conventional
-  `packages.lock.json` files are intentionally absent because NuGet gives that
-  filename precedence over `NuGetLockFilePath`, preventing adjacent neutral
-  and RID graphs.
- `tools/update-package-locks.ps1` is the one intentional update path. The
-  release gate and the launcher's nested Bake publish use forced locked restore,
-  so stale `obj/` assets cannot hide a disagreement and a normal gate cannot
-  rewrite dependency resolution.
-
-Complete maintained build surface:
-
- All 13 tracked .NET tools were repaired against package/owned interfaces,
-  documented in `tools/README.md`, and added to `AcDream.slnx`.
- The gate now verifies that every `.csproj` under `src/`, `tests/`, and
-  `tools/` is a solution member, requires the expected lock graphs, and records
-  their hashes in the evidence bundle. The supported graph is 44 projects.
- The older script/probe archive under F-004 is unchanged. Classifying that
-  historical material remains R6 work; the R2 change only makes the maintained
-  .NET tools truthful and reproducible.
-
-Warning cleanup and test-gate stability:
-
- A clean complete recompilation originally exposed 26 warnings, all in test
-  and diagnostic code. Assertion-specific analyzers, nullable test doubles,
-  and nullable DAT probe boundaries were corrected without changing product
-  behavior.
- The one known redundant historical Core theory input remains for R3 behind a
-  site-scoped `xUnit1025` suppression. The central policy still makes any new
-  duplicate row a build failure.
- The launcher's seven editor-focus variants now execute in one Avalonia test
-  application session. This prevents the headless framework from attempting
-  compositor reinitialization on a non-owning thread. The suite passed 11
-  consecutive focused runs before the full gate. Aggregating seven theory rows
-  into one fact reduces the headline passed count by six; all seven variants
-  are still executed and asserted.
- The launcher package-boundary test now verifies versionless project
-  references against the central version table rather than incorrectly
-  requiring inline versions.
-
-Reproducibility evidence:
-
- Forced locked re-evaluation of all 44 neutral and all 28 RID graphs changed
-  zero lock hashes.
- A locked restore into an empty global package cache, with `--no-cache`,
-  succeeded from the sole configured source. NuGet assets recorded no fallback
-  package folder.
- A forced nested launcher-to-Bake publish selected the appropriate RID graph,
-  emitted the Bake executable, and changed zero lock hashes.
- `pwsh ./tools/run-release-gate.ps1` ran on the clean exact commit
-  `c38f6b88522750abc2e4acf1898ed566c5576e4a`, SDK `10.0.300`, RID `win-x64`,
-  in 121.398 seconds. Restore was forced and locked; all 44 projects built with
-  0 warnings / 0 errors; all 12 test assemblies completed with 14,742 passed /
-  77 skipped / 0 failed. The gate recorded `WorktreeDirty: false`.
-
-No product source behavior changed in this closeout. The known duplicate theory
-row, classification of the 77 environment-dependent skips, test naming/value
-review, and stale public headline counts remain explicitly assigned to R3 and
-the later documentation-authority slice. R2 is complete on the campaign branch.
-
-Rollback is `git revert c38f6b88`; do not rewrite branch history.
-
-## 18. Session start protocol
-
-Every implementation session begins by:
-
-1. reading this plan, the executive audit, and the findings for the active
-   slice;
-2. running `git status --short`, `git rev-parse HEAD`, and checking the ledger's
-   recorded commit against the working tree;
-3. reading all files/tests named by the active finding before editing;
-4. confirming there is no overlapping uncommitted user work;
-5. restating the bounded slice outcome and gates in the session update;
-6. working only the first non-blocked active slice unless the plan explicitly
-   allows parallel work.
-
-## 19. Session handoff protocol
-
-Before ending any session, record in §17 or a linked dated closeout:
-
- exact commit/worktree state and every file changed;
- decisions made and alternatives rejected;
- invariant/evidence destinations for anything removed;
- exact commands, pass/fail/skip counts, timeouts, and artifact paths;
- review findings and whether they were closed;
- remaining risks, blockers, and user/legal decisions;
- rollback command or precise reversal procedure;
- one exact next action that can be started without chat context.
-
-A slice is not `DONE` because its code compiles or a focused test passes. It is
-done only when its exit criteria, complete required gate, evidence update,
-review, and cross-session ledger entry are all complete.
-
-## 20. Immediate next action
-
-Fast-forward `main` through the completed R1–R3 stabilization branch and push
-the merged result. R4 and R5 are explicitly deferred for the friend-only
-release. Before any public release, resume R4; when maintainability work
-resumes, begin with the bounded R5 documentation-authority goal. Do not begin
-bulk comment, artifact, giant-file, or unrelated cleanup first.

-# Campaign LU — launcher usability
-
-**Status: CLOSED USER-ACCEPTED 2026-08-19/20.** Ten slices — the six planned
-plus four the gate rounds added — shipped through CI and accepted live.
-
-**Gate results, in the user's words:** the update flow "works, it updates as it
-should"; the launcher self-update round "pass"; the client's exit back to the
-character selector "pass".
-
-| slice | commit | what it fixed |
-|---|---|---|
-| (blocker) #420 client crash | `a34e8f2a` | character select killed the client mid-paint |
-| LU1 instant startup | `00d12782` | 29.9 s → 0.89 s, measured on the real 27.9 GiB pak |
-| LU2/LU3 one update question | `a01ff426` | six buttons → Update / Not now, self-restarting |
-| LU4 Setup complete | `0a2defb6` | setup ends with a dialog, not a finished progress bar |
-| LU5/LU6 Play + sessions | `09305be6` | one Play per character; rows say who is playing |
-| (cross-cutting) locale | `6a15dd06`, `955c6180` | retail text stopped following the machine's locale |
-| headless CLI + LU7 | `2bff44a9` | headless and character refresh had never run at all |
-| LU8 roster + fold | `18bbd377` | logging in IS the refresh; Play above the fold |
-| LU9/LU10 stop + logout | `6ab5d8ce` | 30 s graceful stop, ACE hold, logout lands on select |
-| verification-cache limit | `7037681a` | the ZFS finding below |
-
-Full solution under the release-gate filter: **14,375 passed, 0 failed,
-0 skipped**, and identical under `sv-SE`, `tr-TR`, `ar-SA` and `de-DE`.
-
---
-
-## What the gate rounds found that the plan did not
-
-Four of the ten slices did not exist when this plan was written. Each came from
-the user running the thing, and each was a defect the automated suite could not
-have surfaced:
-
-**Headless and character refresh had never worked, once.** The launcher spawned
-`acdream-headless --config <path>`; the host reads `arguments[0]` as its command
-and accepts only `validate` or `run`. Every launcher-started headless session
-and every roster refresh died on its first instruction with "Invalid command"
-and exit 64 — visible only as a code in a status file. A whole campaign's gates
-missed it because they drove the headless host through its CLI directly, never
-through the launcher's spec. `LauncherHeadlessCommandLineContractTests` now
-feeds the launcher's real argument vector to the host's real parser.
-
-**Refresh was harmful as well as broken.** It opened a second connection to an
-account purely to read the roster, which the server treats as a new login — so
-using it while playing disconnected you. It was also redundant: every ordinary
-login already carries the roster, and the orchestrator already folds it in.
-
-**Stop was the crash.** The UI gave the client five seconds before killing it,
-which is not enough to send a logout, await the acknowledgement, and tear down a
-mapped 28 GB world. So Stop routinely produced exactly the ungraceful exit that
-leaves the server holding the account.
-
-**Play was below the fold.** The buttons existed; the plugins/login-commands
-form pushed them past the bottom of the scroll area. Reported, correctly, as
-"there is no headless or gui option".
-
-## Findings worth keeping
-
-**The verification cache cannot see a same-size, same-timestamp change.** Run
-174 failed on a test asserting it could. Measured on the runner: `/tmp` is ZFS,
-and 141 of 200 same-size rewrites produced an identical mtime. NTFS's 100 ns
-resolution is the only reason it never showed on Windows. The contract is now
-two true statements — startup catches a corruption whose write time moves, and
-a forced full verification catches one that preserves both — instead of one
-that is false on some filesystems. Verify files is the forced path.
-
-**Testing the launcher does not test your source.** The launcher runs the
-INSTALLED client from the version store, so a client-side fix cannot be gated
-until CI publishes it. A void-world screenshot was read as "the fix failed" when
-the installed build was 63 minutes older than the fix.
-
-**A locally built launcher cannot test self-update.** Its stamped version is
-`1.0.0`, which sorts above every `0.1.0-build.*` the feed publishes, so it is
-never offered an update. Publishing one with a deliberately low
-`InformationalVersion` is what made that path testable at all.
-
-**Goal**
-
-> The launcher opens without a long wait. On startup it asks whether to
-> update the launcher or the client, and restarts itself after a launcher
-> update; the old update flow is gone. First-run setup ends with a success
-> popup that returns you to the launcher on OK. A selected character
-> launches directly. The sessions frame shows account, character (or Char
-> Select) and whether they are in game — not the launch mode.
-
-**Why now.** Campaign LA shipped a launcher that is *correct* — atomic
-installs, verified artifacts, session barriers, rollback — and *not
-usable*. The user's verdict, twice: "way too complex", "too complex for
-sending it to my friends". This campaign changes the surface a person
-touches. It does not weaken what happens underneath.
-
-**Acceptance for the whole campaign** is the user's own walkthrough:
-download `launcher-win-x64.zip` from the `latest` release, unzip, run,
-install, play — without being told anything.
-
---
-
-## LU1 — the launcher opens immediately
-
-**Measured problem.** [App.axaml.cs:57](../../src/AcDream.Launcher/App.axaml.cs)
-blocks the UI thread on `installer.LoadExistingAsync().GetAwaiter().GetResult()`
-before the window is constructed. That reaches
-`LauncherInstallRecordStore.VerifyFileAsync`, which computes a full SHA-256
-of the installed package.
-
-Measured on the user's machine 2026-08-19:
-
-| fact | value |
-|---|---|
-| `%LOCALAPPDATA%\acdream\pak\acdream.pak` | 29,908,271,024 bytes (27.9 GiB) |
-| full SHA-256 | **24.1 s** at 1.16 GB/s |
-| digest vs `install.json` | identical (`fee8595d…`) |
-
-So the startup cost is 24 s of disk read to re-confirm something that was
-already true. A friend does not see it only because they have no package
-installed yet — verification short-circuits at "nothing installed". It
-will hit them the moment first-run setup finishes.
-
-**Change.** Startup verification becomes size + last-write-time against
-the record. The full hash keeps running where it is cheap and meaningful:
-at install, after an update installs a new package, and behind an explicit
-**Verify files** button (the Steam shape).
-
-The cheap facts live in a **sidecar** (`install.verification.json`), not as a
-new field on the install record. `LauncherInstallRecordStore` reads
-`install.json` with `JsonUnmappedMemberHandling.Disallow`, so a new field
-there would make an *older* launcher build reject the record outright and
-demand a 28 GB re-bake after a rollback. An unknown sidecar file is simply
-ignored by older builds, so the change is compatible in both directions.
-An install with no sidecar yet pays one full hash and then writes it.
-
-**Acceptance**
-
- Window visible in under 2 s with the 27.9 GiB package installed.
- Truncating or touching the package still blocks launch with a clear reason.
- **Verify files** reproduces the full check and reports pass/fail.
- The install and update paths still hash in full — unchanged.
-
---
-
-## LU2 — one update question, asked once, at startup
-
-**Change.** On start the launcher checks the feed once. If the launcher or
-the client is behind, it shows **one** dialog naming what is out of date and
-offering **Update** / **Not now**. Nothing else.
-
- Launcher first when the feed's `minimumLauncherVersion` demands it, or
-  when only the launcher is behind: install, then **restart into the new
-  version** (`LauncherSelfUpdateBootstrap` already owns this handoff).
- Client otherwise: install, close the dialog, back at the launcher.
- Nothing to do: no dialog at all. The launcher just opens.
-
-**Acceptance** — three observed cases: up to date (silent), client behind
-(one dialog → play), launcher behind (one dialog → relaunched on the new
-version, confirmed by the version it reports).
-
---
-
-## LU3 — delete the old update surface
-
-The current prompt offers six buttons — Check again, Rollback client,
-Stage launcher, Install client, Cancel, Close — plus a version table and a
-restart-required banner. That is the flow being removed, along with the
-"Check for updates" header button and the `LauncherUpdateViewModel` paths
-only it reached.
-
-**What stays:** everything in `AcDream.Launcher.Core/Updates/` that makes
-an update safe — manifest validation, bounded verified download, safe ZIP
-extraction, versioned install with an atomic `current.json` switch, the
-session barrier, and rollback as a *capability*. The complexity the user
-objects to is the panel, not the safety beneath it.
-
-**Open — needs one confirmation before code is deleted:** rollback has no
-place in the new single-question flow. It can move behind a small
-"Advanced" affordance or leave the UI entirely (staying available as Core
-API + tests). I will show the exact deletion list and ask before removing
-it.
-
-**Acceptance** — exactly one update entry point in the UI; tests covering
-deleted view-model behavior are removed with the code, never skipped.
-
---
-
-## LU4 — "Setup complete" ends first-run setup
-
-**Change.** When the bake publishes and the install record verifies, the
-wizard shows a modal: setup succeeded, what was built, **OK**. OK closes
-the wizard and returns to the launcher with the "Client setup required"
-banner gone and launching enabled.
-
-**Acceptance** — a real first-run bake shows it exactly once on success;
-cancellation and failure paths keep their existing error/status reporting
-and must **not** show it.
-
---
-
-## LU5 — pressing Play on a character launches that character
-
-**Reproduce before changing anything.** The plumbing already exists end to
-end: `LauncherOrchestrator.LaunchAsync` clones the character with the
-*requested* mode (`CloneCharacter(character, mode)`),
-`SessionConfigComposer.BuildSelector` emits an id selector (falling back to
-name), and `RuntimeOptions.MapCharacterSelector` maps it into the App host.
-A defect somewhere in a chain that reads correct is exactly the case this
-project has repeatedly lost time to by guessing.
-
-Two candidates to separate by observation, not argument:
-
-1. The launch button is gated off by a capability reason, so the click
-   never becomes a session.
-2. The selector reaches the client but the roster match fails, so character
-   select stays on screen — which is what "you can just select different
-   chars" describes.
-
-**Change.** One obvious **Play** per character that enters the world as
-that character, plus the deliberate "Character select" path kept separate.
-Three near-identical launch buttons is itself part of the complaint.
-
-**Acceptance** — select a character, press Play, arrive in the world as
-that character with no character-select screen in between.
-
---
-
-## LU6 — the sessions frame says who is playing
-
-Today each row reads `server / account / character`, then `Mode`
-(Gui/GuiSelect/Headless/Probe), then `State`, then a raw status string.
-The launch mode is launcher bookkeeping and means nothing to a player.
-
-**Change.** Each row shows the account, the character — or **Character
-select** when no character was chosen — and one plain status word derived
-from the host's own status stream:
-
-`Starting` → `Character select` → `In game` → `Stopped` / `Failed`
-
-Errors keep their own line. Stop keeps its button. Character-refresh
-(probe) rows stay distinguishable from play sessions.
-
-**Acceptance** — launching a character shows account + name + **In game**
-once in world; a character-select launch shows **Character select** until a
-character is entered.
-
---
-
-## Non-goals
-
- No change to download verification, atomic install, or the session barrier.
- No change to credential handling (plaintext profile remains the user's decision).
- No change to Linux graphical gating (Slice L stays parked).
-
-## Working rules for this campaign
-
- One slice per commit, `dotnet build` + `dotnet test` green before each.
- Push to main; CI gates on both runners and publishes the release the
-  launcher itself updates from — so every slice is testable by the user
-  through the shipped path within a few minutes.
- LU3's deletions and LU5's root cause get shown to the user before they
-  land.
-
---
-
-# Implementation notes (recon 2026-08-19, before any code)
-
-These were read out of the tree, not assumed. They exist so each slice
-starts from the mechanism that is already there instead of re-deriving it.
-
-## The self-update restart chain already exists end to end (LU2)
-
-`LauncherUpdater.StageLauncherAsync` stages a verified payload and writes a
-plan. On the next ordinary startup `LauncherSelfUpdateBootstrap.HandleAsync`
-takes the exclusive lease, sees `SelfUpdatePlanState.Staged`, and spawns the
-STAGED launcher in helper mode. `RunHelperAsync` waits for the parent PID to
-exit, applies the replacement, starts the updated launcher with
-`--acdream-self-update-confirm-v1`, and waits for the confirmation receipt.
-
-So "restart after a launcher update" needs no new update machinery. What it
-needs is one seam: after staging succeeds, start the staged helper against
-the CURRENT process and shut down. Extract the existing staged-plan branch of
-`HandleAsync` into a callable entry point and reuse it — do not duplicate it,
-and do not restart by launching a second copy of the launcher and hoping the
-bootstrap picks the plan up, which races the exclusive lease against the
-process that is still shutting down.
-
-## The orchestrator already knows "in game" (LU6)
-
-`LauncherActivityState` has `InWorld`, and the orchestrator already sets it
-from `EnteredWorldStatusEvent`, which carries the real `CharacterId` and
-`CharacterName` from the host. Today that identity is written into a status
-STRING (`"In world as X."`) and thrown away.
-
-LU6 promotes it: the entered-world event updates the activity's character
-name so a character-select launch can show who is actually being played, and
-the row renders one word derived from `LauncherActivityState` rather than the
-raw enum plus the launch mode:
-
-| state | row shows |
-|---|---|
-| `Starting`, `Running` | Starting |
-| `Connected` | Character select |
-| `InWorld` | In game |
-| `Disconnected`, `Stopping` | Stopping |
-| `Exited`, `Cancelled` | Stopped |
-| `Failed` | Failed |
-
-`LauncherActivityKind.Probe` rows stay visually distinct (they are a
-character refresh, not a play session).
-
-## First-run completion has an exact point (LU4)
-
-`FirstRunInstallerViewModel.StartAsync` succeeds at the line that calls
-`_onInstalled(result.Record)` and sets `Phase = LauncherInstallPhase.Completed`.
-That is where the success dialog belongs — after the record is published, so
-the launcher behind it is already in its launch-enabled state when the user
-presses OK. The cancelled and failed branches immediately below it must not
-reach it.
-
-## The launcher side of "launch this character" reads correct (LU5)
-
-Confirmed by reading, so the live repro can skip re-checking these:
-
- `LauncherOrchestrator.LaunchAsync` -> `CloneCharacter(character, mode)`
-  overrides the profile's saved `LaunchMode` with the mode the button asked
-  for, so the stored default cannot leak into an explicit launch.
- `SessionConfigComposer.Compose` builds a selector for every mode except
-  `GuiSelect`, preferring a parsed non-zero id over the name.
- `SessionPlayerComposition` passes the selector into
-  `LiveSessionConnectOptions` with `AwaitCharacterSelection: selector is null`,
-  and `InteractionRetainedUiComposition` binds the character-selection UI only
-  when the selector is null.
-
-The user's stored profiles all carry `launchMode: "guiSelect"` (the default),
-and every cached character has a real id. So the defect is NOT a missing id
-and NOT the saved default overriding the click. Reproduce live before
-changing anything.

-# Campaign CT — complete chat parity (system + GUI)
-
-**Status:** Groups A, B, C and D COMPLETE 2026-08-21, each user-gated.
-CT-B4 landed 2026-08-21 after the research block turned out to rest on a wrong
-premise (see the slice). One item deliberately not shipped: CT-B3 (word
-filtering — dropped by user direction, register row CT-2).
-
-**Carried forward:** ~~multi-frame state media~~ **DONE 2026-08-21.** The
-importer now keeps the whole authored sequence and `UiMediaSequence` plays it.
-Measuring the real data (`LayoutDump --media 0x1000048C`) corrected the
-behaviour as well as enabling it: the indicator blinks three times over three
-seconds and then hands off to `Ghosted`, hiding itself. Retail's is a transient
-attention-flash, not a badge that stays lit until you scroll down. Register
-rows CT-3, CT-4.
-
-**Goal, set by the user 2026-08-21: complete retail parity for the chat
-system AND the chat GUI.** Not "fix the green name" — that was the symptom
-that started the review. The bar is that a retail player sitting down in front
-of acdream's chat window finds nothing missing and nothing behaving
-differently.
-
-Campaign CH (2026-08-09, closed user-accepted) landed colours, side channels,
-the 152-verb command registry, the window shell and verbatim `/help`. CT is
-the pass that closes what CH did not reach.
-
-Research notes (all 2026-08-21): `chat-texttag-model.md`,
-`chat-tagged-name-composition.md`, `chat-tag-click-dispatch.md`,
-`retail-chat-window-ui.md`, `acdream-text-stack-audit.md`,
-`acdream-chat-ui-audit.md`.
-
-## Definition of done
-
-1. Every retail chat behaviour is either implemented, or has a divergence-
-   register row saying why not.
-2. Every user-visible chat surface has a test that would catch its regression.
-3. The chat digest and `docs/ISSUES.md` describe reality (both are stale today).
-
-## What the review established
-
-### The green clickable name is a TEXT-STACK gap, not a chat gap
-
-The client sprintfs literal markup into the line —
-`<Tell:IIDString:{iid}:{name}>{name}<\Tell> says, "{text}"`, closing marker a
-literal backslash — and `UIElement_Text::InqGlyphs @0x00468EA0` parses the
-brackets while appending, calling `TextTagFactory::MakeTag @0x00478480`. Tags
-attach **per glyph**; a "run" is emergent (adjacent glyphs with equal tag
-pointers). A glyph takes the tag colour (property `0x1D`) only when a tag is
-open AND its `m_type == 0x10000001`, else the line colour (`0x1B`). Only
-senders with a GUID in `0x50000001..0x6FFFFFFF` are tagged.
-
-Colour **measured** from the installed dats (`LayoutDump --colors`), chat
-`0x2100006F` / transcript `0x10000011`: `P0x1B` = RGB(204,204,204),
-`P0x1D` = **RGB(0,178,0)**. The tag colour is per-ELEMENT and authored, while
-the line colour on that same element comes from the runtime chat table —
-filing "tag green" into the LogTextType table would put it in the wrong place.
-
-Click: `UIElement_Text::MouseUp @0x004694F0` → `DeterminePositionFromXY
-@0x004688F0` → `GlyphList::InqGlyph @0x00473430` → virtual `HandleClick` at
-tag-vtable `+0x14` → `gmMainChatUI::RecvNotice_TextTag_IIDStringClick
-@0x004CCE10` → `ChatInterface::StartTell @0x004F41F0`, which writes
-`"@tell {Name}, "`, takes focus, and shows the entry bar. Clicking a name
-always opens a TELL — fellowship, allegiance, patron/vassal and named-channel
-lines all embed the same markup. No hover effect.
-
-### Our side is closer than feared
-
-`UiText` **already** draws multi-coloured runs (`TextRun`/`RunsProvider`, used
-by the character stat panel); it is gated to `OneLine == true`. The draw path
-needs no renderer work — arbitrary pen X, substring measurement — and
-`UiText.HitChar` already resolves a click to (line, column). The blocker is
-that `ChatVM.RecentLinesDetailed()` drops `Sender`/`SenderGuid` one step before
-the renderer, though `ChatEntry` carries them the whole way.
-
-### The command registry is already at parity
-
-All 13 verbs the CH3 research note lists as MISSING were closed by CH4 and
-verified present 2026-08-21 (`cg`, `soc`, `o`, `co-vassals`, `fellows`,
-`group`, `party`, `vassal`, `ab`, `guild`, `ct`, `clfg`, `crp`). `/g` correctly
-resolves to Fellowship, confirmed against the live retail client. That note's
-"acdream status" columns are stale and now carry a correction banner.
-
-## Slices
-
-### Group A — the tagged-text capability (strict chain, A1→A5)
-
-Nothing is user-visible until A4.
-
- **CT-A1** Multi-line text elements carry coloured runs. Additive; the ~50
-  files using `Line` are untouched. No behaviour change.
- **CT-A2** Parse the tag markup into runs with a tag payload, including
-  retail's rule that an unparseable bracket closes the open tag. Pure, unit-
-  testable, no UI.
- **CT-A3** Stop flattening: carry sender name + guid through `ChatVM` into
-  spans, and compose retail's markup in the speech handlers behind the
-  player-GUID-range gate.
- **CT-A4** Apply the authored `0x1D` tag colour when a tag is open and its
-  type matches. **Names turn green.**
- **CT-A5** Sub-line hit-testing and `StartTell`. **Names become clickable.**
-
-### Group B — chat SYSTEM behaviours
-
- **CT-B1** Bound the transcript: 10,000 chars, trim to ~7,500 preferring a
-  newline boundary (`TruncateChatLog @0x004F4290`). Today it grows for the life
-  of the session — a slow leak, not only a fidelity gap.
- **CT-B2** Text-replacement macros: typing `/r `, `/t `, `/tell ` rewrites the
-  input to `@tell {LastTeller}, ` on the space keypress
-  (`HandleTextReplacements @0x004F50D0`). The commands already work; the
-  visible expansion does not exist.
- **CT-B3** ~~`FilterLanguage` word filtering~~ — **DROPPED by user direction
-  (2026-08-21): "I do not want any censoring."** acdream keeps the option
-  itself, which still stores and ships its bit to the server exactly as retail
-  does, but performs no client-side substitution. Registered as CT-2 rather
-  than left as an implicit gap, since it IS a knowing departure from retail
-  (`PlayerModule::FilterLanguage` + `TabooTableAdaptor::CheckCensorsW
-  @0x00682A30` inside `AddTextToScroll`).
-
-  Worth keeping on record, because the attempt established two things that
-  would otherwise be rediscovered if this is ever revisited:
-
-  1. The table's dat id is not readable from the decomp — `CheckCensorsW`
-     reaches it through `DBObj::GetByEnum` with the arguments elided by Binary
-     Ninja. The portal master enum map (`0x25000000`) has 22 categories, with
-     category 3 (`0x0E010001`, `0x0E010002`) and the single-entry categories 8
-     and 11 the plausible candidates.
-  2. Chorizite.DatReaderWriter declares a `TabooTable` type but does NOT decode
-     it — only `DBObjType` and `HeaderFlags`. The format would have to be
-     decoded here first.
-
-  And the matching is an algorithm, not a word list:
-  `TabooTable::CreateCheckString @0x00681570` normalises a candidate before
-  `StringMatchesFilter @0x00681600` compares it, which is how retail catches
-  obfuscated spellings.
- **CT-B4** ~~The plain-text session chat log~~ **DONE — and the premise was
-  wrong.** There is no automatic session log to have a path for. Retail's
-  `@log` is a COMMAND: `ClientCommunicationSystem::DoSetOutput @0x0057E4F0`
-  takes a filename, `StartCopyOutputToFile @0x0057C8A0` does the
-  `fopen(name, "a+")`, and running it again with no argument closes it. So
-  "path and rotation UNKNOWN" was asking a question the design does not have:
-  the player names the file, and there is no rotation because it appends
-  forever.
-
-  The path question that DOES exist — where a bare name lands — is answered by
-  retail's own help text, which the CH4 help table already carried verbatim
-  without anyone reading it: "a log file named Aclog.txt **in your Asheron's
-  Call directory**". acdream cannot use the install directory (the launcher
-  replaces it atomically on update), so a bare name lands in the client's own
-  log directory. Rooted paths are honoured verbatim. Register row CT-5.
-
-  Landed with it: the verb registered in the catalog (it had a help entry
-  since CH4 but no catalog entry, so `/log` printed help and did nothing),
-  retail's `.txt`-for-extensionless rule, all five reply strings byte-decoded
-  from the paired binary, and the writer attached at OPEN so only text after
-  the command is copied. The line logged is the composed display line with the
-  shared timestamp, because retail's `fprintf` sits inside `AddTextToScroll`
-  — downstream of composition, upstream of glyph layout.
-
-### Group C — chat GUI
-
- **CT-C1** Auto-scroll vs unread: retail samples "was at bottom" BEFORE the
-  line lands; if you had scrolled up it leaves you there and lights the unread
-  indicator (`0x1000048C`), which scrolls to bottom and clears on click.
- **CT-C2** Escape in the chat input is a complete no-op — `UiField` has no
-  `Escape` case, and a focused field also suppresses the input dispatcher's
-  fallback, so there is no clear, no defocus and no hotkey passthrough.
- **CT-C3** Option-gated timestamp prefix (`%#H:%M:%S `, colour index `0x0C`,
-  grey), gated on `PlayerModule::DisplayTimeStamps()`.
- **CT-C4** Input-bar editing parity: clipboard and selection paths
-  (Ctrl+C/X/V, shift-selection) work but are untested; `ToggleMaximize` and the
-  floating-window Close button have zero coverage. **DEFERRED** — pure test
-  coverage over behaviour the audit confirmed already works, so it changes
-  nothing a user can see. Worth doing; not worth blocking the campaign on.
-
-### Group D — hygiene
-
- **CT-D1** ~~Delete the dead ImGui-era `ChatPanel`~~ **DONE.** Verified never
-  constructed in `src/`, then removed with its three panel-only test files.
-  `ChatVMCombatTests` was KEPT — three of its four tests are real `ChatVM`
-  coverage; only the one `ChatPanel` render test went.
- **CT-D2** ~~Reconcile the chat digest and `docs/ISSUES.md`~~ **DONE.**
-  `docs/ISSUES.md` turned out to be ACCURATE already — #358 and #363 are
-  recorded CLOSED there. Only the chat digest's "Open" section was stale, and
-  it is corrected: genuinely open are #359, #360, #361, #366. The digest also
-  gained a Campaign CT section and three new DO-NOT-RETRY rows.
-
-## Research still owed before the affected slices
-
- The tag-type roster behind `m_type == 0x10000001` — only "Tell" is
-  confirmed; the full set lives in the DAT `EnumMapper` category `0x18`.
-  Blocks nothing in Group A, but decides whether other tag shapes exist.
- Whether retail's transcript supports text selection distinctly from the
-  entry field (blocks CT-C4's scope).
- Whether a chat-specific sound cue exists — a grep came back empty, which is
-  weak evidence, not proof of absence.
-
-## Deliberately NOT in scope
-
-Item links and the other three tag shapes (`DID`, `IID`, `IIDEnum`). They have
-no listener in the retail build we target, so porting them would be inventing
-behaviour. CT-A5's dispatch is generic, so they cost nothing to add later.

-# Campaign QT — the contract tracker (H.3's client half)
-
-**Status:** CLOSED USER-ACCEPTED 2026-08-21. All six slices landed and the
-connected gate passed, together with Campaign QJ's two tabs.
-
-**Why now.** M4's demo scenario is "talk to an NPC, accept a quest, ... complete
-the quest." Everything in that sentence works today EXCEPT the player's ability
-to see what they have accepted. NPC dialogue, emote text, soul emotes, tells and
-the quest-failure strings all render; Campaign CT (closed 2026-08-21) added the
-`<Tell:IIDString:…>` markup those dialog lines carry. What is missing is the
-only STRUCTURED view of quest state a retail client ever gets.
-
-**What H.3 is not.** The roadmap line reads "122 EmoteType × 39 Trigger
-mini-VM", which describes the SERVER's job. Per `r10-quest-dialogs.md` §1.3 the
-retail client never stores a quest flag, never evaluates an emote, and is never
-told a flag changed. It learns about quests three ways: dialog strings the
-server already formatted, generic error toasts, and the contract tracker. Two of
-the three ship. So H.3's remaining client scope is this campaign, and the emote
-VM is explicitly out of it.
-
-## Measured ground truth
-
-### The panel
-
-`LayoutDump --find 0x1000004B` (the `UIElement::RegisterElementClass` id from
-`gmContractsUI::Register @0x00499C80` — registration keys on the element's
-**Type**, not its id) finds the class in six layouts. `0x21000069` holds it as a
-standalone 300x500 root (`0x100005CD`); the rest embed it at 300x575 inside
-window chrome.
-
-Authored children of `0x100005CD`:
-
-| Element | Type | Rect | Reading |
-|---|---|---|---|
-| `0x100005CE` | 1 | 8,8 80x18 | header button |
-| `0x100005D6` | 1 | 160,8 80x18 | header button |
-| `0x100005CF` | 5 | 8,30 270x298 | the contract list |
-| `0x100005D0` | 11 | 278,30 16x298 | its scrollbar |
-| `0x100005D8`/`0x100005DF` | 12 | y=332 | label / value |
-| `0x100005D9`/`0x100005E0` | 12 | y=352 | label / value |

-| `0x100005DB`/`0x100005E2` | 12 | y=392 | label / value |
-| `0x100005DE` | 12 | 8,418 270x52 | description block |
-| `0x100005DD`, `0x100005E3`, `0x100005DC` | 12/12/1 | y=468 | button row |
-
-### The wire
-
-Both opcodes are already NAMED in `GameEventType.cs` and nothing parses them —
-the bytes arrive and are dropped.
-
-`0x0315 SendClientContractTracker` — one tracker plus two flags:
-
-```
-uint32 Version
-uint32 ContractId
-uint32 Stage
-double TimeWhenDone
-double TimeWhenRepeats
-uint32 DeleteContract         (bool widened)
-uint32 SetAsDisplayContract   (bool widened)
-```
-
-`0x0314 SendClientContractTrackerTable` — a full replacement, as a packable
-hash table (`PackableHashTable<unsigned long, CContractTracker>` in the decomp
-at `0x00497C10`): the familiar `u16 count` / `u16 numBuckets` header, then
-`u32 key` + the 28-byte tracker per entry. NO trailing flags on this path.
-
-Source: `ContractTrackerExtensions.Write`, `GameEventSendClientContractTracker`,
-`ContractManager.Write` in ACE; cross-checked against the retail decomp's own
-`PackableHashTable<unsigned long,CContractTracker>` instantiations.
-
-`ContractStage`: `1` Available, `2` InProgress, `3` DoneOrPendingRepeat,
-`4 + n` ProgressCounter with n steps done.
-
-### `gmContractsUI::FillProgressString @0x00498DE0` — the one real algorithm
-
-Recovered whole. The x87 compares are the standard `fcom` + `sahf` pattern;
-`(status & 0x41) != 0` tests C0|C3, i.e. **<= 0**.
-
-```
-stage 1                    -> "Available"
-stage 2                    -> "In Progress"
-stage 3:
-    if TimeWhenRepeats <= 0
-        -> QuestflagRepeatTime empty ? "Done" : "Available"
-    remaining = TimeWhenRepeats - (now - timeOfServerUpdate)
-    if remaining <= 0      -> "Available"
-    else                   -> "Done (" + DeltaTimeToString(remaining) + " to Repeat)"
-stage >= 4:
-    if DescriptionProgress empty -> "In Progress"
-    else                         -> sprintf(DescriptionProgress, stage - 4)
-```
-
-Three things a reimplementation would get wrong:
-
-1. **`TimeWhenDone` is never read.** Only `TimeWhenRepeats` drives the text.
-2. **`timeOfServerUpdate` is not on the wire.** The client stamps arrival and
-   counts down from its own clock, so the countdown has to be anchored at parse
-   time, not recomputed from the server value each frame.
-3. **`DescriptionProgress` is a printf format** taking one integer, `stage - 4`.
-   It is not a literal string.
-
-### It is not a "contract panel" — it is tab 1 of the JOURNAL panel
-
-Measured from the installed dats. Host `0x2100006E`, `gmPanelUI` slot
-`0x10000559`, whose own authored `0x10000029` is **`0x19` = 25** — the same
-slot-key recipe `RetailPanelCatalog` already uses for Options (10), the social
-panel (12) and Map/House (16). Three tabs:
-
-| Tab | Caption | Page | Page type |
-|---|---|---|---|
-| `0x100005D3` | **Contracts** | `0x100005D4` | `0x1000004B` = `gmContractsUI` |
-| `0x10000560` | **Journal** | `0x10000563` | `0x10000048` — notes: "Title:", "Notes:", "First" |
-| `0x10000561` | **Page List** | — | — |
-
-`0x10000562` (type 1, at 276,0) is the panel's own corner button.
-
-Only the Contracts tab is in scope. The Journal notes page and Page List are
-their own feature and are NOT part of Campaign QT — mounting the panel with two
-dead tabs is the expected intermediate state, not a defect.
-
-### The contracts page, resolved
-
-Authored text read out of the dats (`LayoutDump --props`, which now resolves
-`StringInfo` rather than printing the type name):
-
-| Element | Role |
-|---|---|
-| `0x100005CE` / `0x100005D6` | list column headers — "Contract" / "Status" |
-| `0x100005CF` (type 5) | the list, scrollbar `0x100005D0` via property `0x72` |
-| `0x100005D1` / `0x100005D2` | per-ROW children: contract name / progress text |
-| `0x100005D8` → `0x100005DF` | "Status:" → value |
-| `0x100005D9` → `0x100005E0` | "Contact:" → value |
-| `0x100005DA` → `0x100005E1` | "Contact Location:" → value |
-| `0x100005DB` → `0x100005E2` | "Quest Location:" → value |
-| `0x100005DE` | description block (270x52, wrapping) |
-| `0x100005DD` → `0x100005E3` | "Timed:" → value |
-| `0x100005DC` | "Abandon" button |
-
-`gmContractsUI::RefreshContractListbox @0x00499830` walks the tracker list and,
-per row, sets `0x100005D1` from the contract's name and `0x100005D2` from
-`FillProgressString`, caching the result back into the row. The list is a
-`UiTemplateListBox` here — the same widget OP2 built for the Options panel — so
-the page is binding rather than new widget work.
-
-## Slices
-
- **QT1 — wire.** Typed records + parsers for `0x0314`/`0x0315`, arrival stamp
-  included. Pure; no UI, no state ownership.
- **QT2 — dat.** Read `ContractTable`/`Contract` (name, description, progress
-  description, NPC names, the three positions). Nothing reads it today; the
-  only reference in the tree counts them in a CLI diagnostic.
- **QT3 — state.** `RuntimeContractState` as a session-scoped J4-style owner:
-  full replace, single add/update, delete, and the display-contract selection.
-  Clears at generation reset.
- **QT4 — the progress string.** Port `FillProgressString` + the retail
-  `DeltaTimeToString` it calls. Table-driven tests over every stage arm.
- **QT5 — the panel.** Register slot 25 in `RetailPanelCatalog`, mount the
-  Journal panel by the OP3/FA recipe, and bind the Contracts page: rows from
-  `IRuntimeContractView` x `ContractCatalog`, progress from QT4, selection
-  driving the detail pane. The other two tabs mount empty.
- **QT6 — open/close.** The open path (no toolbar button authors slot 25, so
-  it is keyboard or menu — to be measured the way FA's F3/F4 was), plus the
-  plugin-visible read surface from `r10-quest-dialogs.md` §11.6.
-
-### Landed
-
-QT1 `ab3934e2` (wire), QT3 `f629ce7f` (state + routing), QT2/QT4 `ef6b7310`
-(catalog + progress string), QT5/QT6 (the panel and its open path).
-
-**The open path needed no new keybind.** Toolbar button `0x1000055A` authors
-`0x10000029 = 0x19` and has been in `ToolbarController.PanelButtonIds` since
-the toolbar was ported — it simply had no panel registered behind it, so
-clicking it did nothing. Registering slot 25 completed a wiring that was
-already three-quarters present.
-
-**The plugin surface** (`r10-quest-dialogs.md` §11.6's contract half) ships as
-`IGameState.Contracts`, projected through `ContractPluginProjection` — a
-pull-through view of the canonical tracker, never a mirror. Both hosts
-implement it; the headless one carries the numeric fields without the authored
-text, since a bot has no dat access. The rest of §11.6 (chat stream, tells,
-give, use, confirmations) is other features and stays out of Campaign QT.
-
-### Owed
-
- The connected user gate: accept a quest against live ACE, open the Journal
-  panel, confirm the list, the progress column and a repeat countdown.
- ~~The Abandon button is deliberately unwired~~ **WIRED 2026-08-21.** The
-  claim that it had no wire message was wrong: it is game action `0x0316`
-  carrying one contract id, and ACE answers with the `0x0315` delete QT3
-  already handles. Nothing is removed locally, so a refused abandon leaves the
-  quest visibly intact.
- The Journal notes page and Page List tabs mount inert, by design.
-
-## Definition of done
-
-1. Accepting a quest against live ACE shows it in the panel; completing it
-   updates the stage; a repeatable one shows its countdown.
-2. Every ported algorithm cites its retail address.
-3. Every slice has a test that would catch its regression.

-# Campaign QJ — the Journal and Page List tabs
-
-**Status:** CLOSED USER-ACCEPTED 2026-08-21. All five slices landed and the
-connected gate passed.
-
-The gate took four rounds, and every defect it found was the same mistake in a
-different place — an element bound as the wrong thing, or a binding never
-tested:
-
-1. **Button property `0x0D`** read as "starts disabled", which killed every
-   button on the panel (register QJ-2).
-2. **The location readout** is authored EDITABLE, so it is a `UiField`; bound
-   as `UiText` it silently discarded every write — the value reached the model
-   and the file and never the screen.
-3. **Handlers deferred their redraw** to the next frame's `Tick` where retail
-   redraws at the click.
-4. **The timer's unit labels** stayed visible behind the running readout,
-   because retail's `ShowEditableTimer` toggles each box AND its label.
-
-Round 3's "Record does nothing" turned out not to be a defect at all: the
-character was indoors, where retail's own `gid_to_lcoord` fails and nothing is
-recorded. Faithful, and now commented so it does not read as a gap.
-
-The durable outcome is `JournalPanelLiveBindTests` — see
-`claude-memory/feedback_test_the_binding_seam.md`. Completes the panel Campaign QT mounted: QT
-shipped the Contracts tab and left the other two inert by design.
-
-**Scope:** retail's `gmJournalUI` (element type `0x10000048`, page
-`0x10000563`) and `gmPageListUI` (type `0x10000049`, page `0x10000564`).
-
-## What this actually is
-
-A **per-character notebook**, entirely client-side. No wire, no server
-involvement, no dat content — the player writes the pages. Each page carries a
-label, a title, free-form notes, a recorded LOCATION, and a countdown TIMER.
-The Page List tab is a searchable index over those pages.
-
-Nothing about it depends on quests; it shares the panel with Contracts and
-nothing else. That it is called "Journal" while the panel is also called
-"Journal" is retail's own naming, not a mistake here.
-
-## Measured ground truth
-
-### The file format
-
-`gmJournalUI::SavePages @0x00497270` / `LoadPages @0x00496AC0`. A plain tagged
-text file, `fopen` mode `w+`. Both call sites pass the literal prefix
-`"Journal"`; the path template is `%s%s-%s-%s.txt`, i.e.
-`{dir}Journal-{server}-{character}.txt`.
-
-```
-<NEWP>            begins a page (a file that does not open with one is refused)
-<PNUM> %d         page number
-<LABE> %s         label      (authored max length 16)

-  that does not open with `<NEWP>`. Pure; no UI, no state ownership.
- **QJ2 — the owner.** `RuntimeJournalState`: the page collection, the current
-  page, new/delete/goto, and the timer. Per-character.
- **QJ3 — the Journal page.** Edit boxes, page navigation, Record, and the
-  editable/running timer swap.
- **QJ4 — the Page List page.** The list, the search, delete, and
-  double-click-to-open.
- **QJ5 — persistence.** Load on character enter, save on exit, under the
-  client's own data directory.

-# Complete Release gate
-
-The default release gate is repository-owned and uses the SDK feature band in
-`global.json`:
-
-```powershell
-pwsh ./tools/run-release-gate.ps1
-```
-
-The command verifies that `AcDream.slnx` contains every `.csproj` under `src/`,
-`tests/`, and `tools/`, performs a locked restore, builds that complete graph,
-then discovers and runs every hermetic test in every default test assembly once
-in a fresh Release process. It does not retry failures. Tests carrying an
-explicit non-hermetic `Lane` trait (`InstalledDat`, `PreparedPackage`, `Live`,
-`Manual`, `Timing`, `Windows`, `Linux`, or `SystemFont`), `Purpose=Diagnostic`, or
-`Status=KnownFailure` are excluded from the hermetic total and run through
-their owned lane instead. The graph currently contains 44 projects,
-including all 13 maintained .NET tools; data-dependent tools are built but are
-not executed as tests.
-
-Build and dependency policy is repository-owned:
-
- `global.json` pins the accepted .NET SDK feature band;
- `Directory.Build.props` supplies the common target framework, language,
-  nullable, analyzer, warnings-as-errors, deterministic-build, and lock-file
-  settings;
- `Directory.Packages.props` is the only direct package-version table;
- `NuGet.Config` clears machine sources and permits only `nuget.org`; and
- each supported project commits its own `packages.neutral.lock.json`; shipped
-  source projects also commit `packages.win-x64.lock.json` and
-  `packages.linux-x64.lock.json` for RID-specific publishes.
-
-The nonstandard neutral name is intentional. NuGet always prefers a
-conventional `packages.lock.json` when one exists, even when
-`NuGetLockFilePath` selects a RID-specific file. Do not introduce conventional
-lock files beside these three repository-owned graphs.
-
-The gate uses `dotnet restore --locked-mode --force-evaluate`. The forced
-evaluation makes the result independent of stale `obj/` assets; locked mode
-still prevents rewriting. If a project or central package version disagrees
-with a committed lock file, restore fails instead of silently changing the
-dependency graph. The launcher's nested Bake publish uses the matching
-RID-specific lock and the same forced locked evaluation.
-
-Each restore, build, and test process has an outer hard timeout. Every test
-also runs with VSTest blame-hang enabled: after three minutes in one test, the
-test host is terminated and a mini dump is collected; after ten minutes, the
-outer watchdog kills the complete `dotnet test` process tree. CI additionally
-has a 45-minute job bound.
-
-Evidence is written to `artifacts/release-gate/`:
-
- `release-gate-summary.json` records the commit, branch, worktree state, SDK,
-  RID, bounds, process outcomes, assembly list, and
-  executed/passed/skipped/failed totals;
- `environment.txt` records `dotnet --info`, configured NuGet sources, and the
-  supported project set, package-lock hashes, and discovered test-project set;
- `test-results/` contains one TRX per assembly plus any VSTest hang sequence
-  and dump files;
- `logs/` contains the exact command and complete output for every child
-  process; and
- `SHA256SUMS.txt` hashes the evidence bundle.
-
-The complete gate runs on Windows because it exercises the full product and
-launcher surface. Hosted GitHub Actions execution is deliberately parked as of
-2026-08-18 while runner policy is decided; the checked-in workflow definitions
-are preserved for later use. Until then, the repository command above is the
-authoritative gate. Focused portability or Vulkan jobs are not substitutes for
-the complete gate.
-
-The JSON summary records the exact test filter. Environment-dependent,
-diagnostic, manual, and known-failure results must be published as their own
-lane and must never be added to the hermetic pass headline.
-
-## The Timing lane
-
-`Lane=Timing` marks tests whose outcome depends on **real elapsed time or OS
-scheduling** rather than on logic: simulated packet-loss soaks, a virtual-clock
-transport session that still waits on wall-clock windows, signalling a real
-child process, orphaned-process restart recovery. They pass on an idle machine
-and fail intermittently under full-assembly load, so they cannot gate a push
-without making the gate untrustworthy.
-
-They are not weakened or deleted — run them deliberately, on a machine that is
-not saturated:
-
-```powershell
-pwsh ./tools/run-release-gate.ps1 -SkipRestore -SkipBuild `
-  -TestFilter 'Lane=Timing&Status!=KnownFailure&Purpose!=Diagnostic'
-```
-
-Measured before laning: on the 6-core Linux runner, three stress rounds of the
-full suite failed `GracefulStopSignalSendsSigintToARealChildOnLinux` 3/3 (it
-passes in ~47 ms alone) and two loss-simulation tests 1/3 each. Chasing them one
-at a time did not converge — four separate fixes, each surfacing a different
-member of the same family, and one of those fixes regressed the other platform.
-
-Add to this lane only with evidence that a test fails under load and passes in
-isolation. A test that fails consistently is a bug, not a timing lane member.
-
-## Continuous integration
-
-This document owns the LOCAL gate. Pushes to `main` are gated on self-hosted
-runners and publish alpha releases — see
-[`ci-and-releases.md`](ci-and-releases.md). Note that CI deliberately does NOT
-invoke `run-release-gate.ps1`: that script redirects child output to log files,
-and Forgejo fails a task that stops reporting as a zombie.
-
-## Non-hermetic test lanes
-
-Installed-DAT tests require an explicit opt-in and a retail DAT directory:
-
-```powershell
-$env:ACDREAM_RUN_INSTALLED_DAT_TESTS = '1'
-$env:ACDREAM_DAT_DIR = 'C:\path\to\Asherons Call'
-pwsh ./tools/run-release-gate.ps1 -SkipRestore -SkipBuild `
-  -TestFilter 'Lane=InstalledDat&Status!=KnownFailure&Purpose!=Diagnostic'
-```
-
-The prepared-package lane additionally requires a validated `acdream.pak`
-beside the DATs or at `ACDREAM_PAK_PATH`:
-
-```powershell
-$env:ACDREAM_DAT_DIR = 'C:\path\to\Asherons Call'
-$env:ACDREAM_PAK_PATH = 'C:\path\to\acdream.pak'
-pwsh ./tools/run-release-gate.ps1 -SkipRestore -SkipBuild `
-  -TestFilter 'Lane=PreparedPackage&Status!=KnownFailure&Purpose!=Diagnostic'
-```
-
-Regenerate all committed UI fixtures through the one comprehensive manual
-generator (the former chat/radar-only generators were redundant):
-
-```powershell
-$env:ACDREAM_REGENERATE_UI_FIXTURES = '1'
-$env:ACDREAM_DAT_DIR = 'C:\path\to\Asherons Call'
-dotnet test tests/AcDream.App.Tests/AcDream.App.Tests.csproj -c Release `
-  --filter 'Lane=Manual&ManualTask=FixtureGeneration'
-```
-
-The retained live-DAT probes are manual evidence, not InstalledDat regression
-contracts. Run each opt-in family independently so a probe command can never
-regenerate fixtures as a side effect:
-
-```powershell
-$env:ACDREAM_DAT_DIR = 'C:\path\to\Asherons Call'
-$env:ACDREAM_PROBE_LIVE_MOUNT = '1'
-dotnet test tests/AcDream.App.Tests/AcDream.App.Tests.csproj -c Release `
-  --filter 'Lane=Manual&ManualTask=LiveMountProbe'
-
-$env:ACDREAM_PROBE_POWERBAR = '1'
-dotnet test tests/AcDream.App.Tests/AcDream.App.Tests.csproj -c Release `
-  --filter 'Lane=Manual&ManualTask=PowerbarProbe'
-```
-
-Known failures (`Status=KnownFailure`) are never part of a green release total.
-Run them explicitly with their prerequisite lane configured; a failure is
-expected until the linked defect is fixed. Diagnostic apparatus
-(`Purpose=Diagnostic`) likewise reports separately and does not inflate the
-contract-test pass count.
-
-The current diagnostic apparatus lives in App and Core. It is retained for
-investigation output, and several methods require installed DATs:
-
-```powershell
-dotnet test tests/AcDream.App.Tests/AcDream.App.Tests.csproj -c Release `
-  --filter 'Purpose=Diagnostic&Lane!=Manual'
-dotnet test tests/AcDream.Core.Tests/AcDream.Core.Tests.csproj -c Release `
-  --filter 'Purpose=Diagnostic&Lane!=Manual'
-```
-
-Operating-system contracts are likewise explicit. Run `Lane=Windows` on a
-Windows host and `Lane=Linux` on a native Linux host; a lane is not portable
-evidence when executed on the other operating system.
-
-`Lane=SystemFont` exercises the BitmapFont path against a host-provided TTF.
-It is separate because the supported runtime can legitimately have none of the
-well-known development fonts installed.
-
-## Updating dependencies
-
-Do not edit lock files by hand. To make an intentional dependency change:
-
-1. Change the version once in `Directory.Packages.props` (or add/remove a
-   versionless `PackageReference` in a project).
-2. Regenerate the neutral graph and both supported release-RID graphs from the
-   repository root:
-
-   ```powershell
-   pwsh ./tools/update-package-locks.ps1
-   ```
-
-3. Review the central-version and `packages.*.lock.json` diffs.
-4. Prove locked resolution and run the gate:
-
-   ```powershell
-   dotnet restore AcDream.slnx --locked-mode --force-evaluate
-   pwsh ./tools/run-release-gate.ps1
-   ```

-# #265 capture-driven bisection — steep-slope response family
-
-**Status: FIX IMPLEMENTED 2026-07-30 (same day, §9 as-fixed addendum) —
-closure pends the user's visual-gate acceptance.** S1 and S2 both CLEARED
-for the two concrete mined events; the real mechanism was a pre-existing
-(frozen-phase) architecture, not a Campaign P regression — §1-§8 below are
-the original bisection pass (research-only, no production code changed
-at that point). §9 records what was actually implemented against that
-verdict: `PlayerMovementController.cs`'s grounded residual-velocity zero is
-removed for the animation-root-motion path, and `PhysicsEngine.cs` now
-wires `PhysicsBody.GroundNormal` from the committed contact plane. The
-harness (committed,
-`tests/AcDream.Core.Tests/Physics/Issue265SteepSlopeCaptureBisectTests.cs`)
-and mining tool (`tools/analyze_265_steep_slope_capture.py`) are permanent;
-the A/B code toggles described in §3 were applied and reverted locally
-and never committed (they remain historical — the actual fix is
-unrelated to S1/S2, see §9).
-
-## 0. Scope recap
-
-Issue #265 (`docs/ISSUES.md`): after the TS-4-removal-then-revert
-(`2e27d066`+`a8a7d64b`), the live matrix gate (2026-07-30, scenarios 4/5)
-found three symptoms: (a) jumping INTO an uphill slope bounces (retail does
-not), (b) house-roof slides no longer happen, (c) occasional
-stuck-sliding-on-an-edge. Two remaining Campaign-P suspects were named:
-
- **S1** — `db2889af` ("#116 shape-1"): `BSPQuery.cs` Path-6's `hasSphere1`
-  (head-sphere-only hit while airborne, foot sphere clear) branch changed
-  from a steepness-gated dual path (steep → slide-tangent-then-`Slid`;
-  shallow → `SetCollide`+`Adjusted`) to an unconditional
-  `SetCollisionNormal` + `return Collided`.
- **S2** — the AP-7 `calc_friction` threshold rewrite (merge `26e0334a`):
-  `0.0` → `0.25`, unconditional into-plane velocity subtraction past the
-  threshold.
-
-## 1. Segment mining
-
-Captures used: `artifacts/matrix-session2-resolve.jsonl` (15,726 records,
-copied from the coordinator worktree's `artifacts/matrix-session2-resolve.jsonl`)
-and `artifacts/matrix-session3-resolve.jsonl` (12,145 records at copy time).
-
-**Session3 is not usable.** Every one of its 12,145 records shows the
-identical position `(60.372223, 9.071998, 79.344925)`, zero velocity, and
-`transientState=3` (Contact|OnWalkable) from tick 0 to tick 12144 — the
-player was standing perfectly still (likely AFK / alt-tabbed) for the
-entire ~7.2-minute capture window. It contains no motion at all and was
-excluded from further analysis.
-
-### 1.1 First pass — strict signature scan (`tools/analyze_265_steep_slope_capture.py`)
-
-Two signatures were scanned for directly on the JSONL fields:
-
- **Signature A (uphill-jump bounce)**: an airborne record (`bodyBefore`
-  Contact bit clear) with `result.collisionNormalValid=true` and a "steep,
-  non-floor, non-wall" normal (`0.02 < normal.Z < FloorZ=0.6642`), followed
-  by a next-tick upward jump in `bodyBefore.velocity.z` while still
-  airborne.
- **Signature B (lost-slide / edge-wedge)**: ≥6 consecutive ticks with
-  Contact set but OnWalkable clear (resting against a non-walkable steep
-  surface), a non-trivial requested move each tick, and near-zero net
-  advance.
-
-**Result: 0 hits for both signatures, in both files.** Session2 has only
-38 `collisionNormalValid=true` records total (out of 15,726), and every one
-of them has `normal.Z` in the `[0.85, 1.0]` bucket — i.e. every reported
-collision normal in this capture is CLOSE TO FLAT/floor-like, never in the
-"genuinely steep" `< FloorZ` band my first-pass signature targeted. This is
-an honest negative result for the specific "steep" heuristic; the actual
-symptom-bearing frames, mined below, are moderate-angle (Z≈0.86–0.95,
-above `FloorZ` — walkable BY THE THRESHOLD) and are found by a different
-signature.
-
-### 1.2 Second pass — velocity-annihilation scan
-
-Widened the signature to "a tick where `|horizontal velocity|` before is
-`>2 m/s` and after (next tick) is `<0.05 m/s`, then how long the position
-stays frozen afterward." This found exactly **two events**, both in
-session2:
-
-| idx (0-based) | tick | `|v_horiz|` before | frozen for | cell |
-|---|---|---|---|---|
-| 3153 | 3153 | 8.90 m/s | 46+ ticks (session2 continues past it; not EOF) | `0xAAB30007` |
-| **3434** | **3434** | **18.00 m/s** | **12,292 ticks — to EOF** | `0xAAB40011` |
-
-**Event at idx 3433/3434 (the primary oracle for this pass), full trace**
-(`records[3415..3434+41]`, printed via ad-hoc Python — see
-`tools/analyze_265_steep_slope_capture.py` for the reusable scanner):
-
- Ticks 3415–3432: clean ballistic fall. `vBefore = (11.15, 14.13, vz)`
-  with `vz` accumulating from ‑16.72 to ‑23.14 (pure gravity, no further
-  horizontal drive — a jump/leap with residual momentum, exactly the kind
-  of trajectory the oracle plan's §1.3 predicted would NOT hit the
-  TS-4 degenerate case). `Z` falls from 92.79 to 79.90.
- **Tick 3433 (the landing):** `result.collisionNormalValid=true`,
-  `result.collisionNormal=(0.2857143, 0.42857143, 0.85714287)` — exactly
-  `(2,3,6)/7`, a REAL polygon normal (not the `UnitZ` degenerate default).
-  `result.isOnGround=true`. `bodyAfter.contactPlaneValid=true`,
-  `bodyAfter.walkablePolygonValid=true`, `bodyAfter.walkableVertices` = the
-  triangle `(240,0,88), (264,0,80), (264,24,68)` — `normal.Z=0.857`, well
-  ABOVE `PhysicsGlobals.FloorZ` (0.6642): **a legitimately walkable roof
-  slope, not the "steep, non-walkable" case either S1 or the original TS-4
-  shortcut ever targeted.** `bodyAfter.velocity` is UNCHANGED
-  `(11.15,14.13,‑23.14)` — confirms (see `PhysicsEngine.cs:1489`, capture
-  fires inside `ResolveWithTransition`, before any caller-side velocity
-  response) that neither `calc_friction` nor `HandleAllCollisions` ran yet.
- **Tick 3434 (the very next resolve call):** `input.currentPos ==
-  input.targetPos` (ZERO requested motion this tick — the previous frame's
-  integration already produced zero displacement). `bodyBefore.velocity =
-  (0, 0, 0)` — **already fully zeroed by the time THIS resolve call even
-  starts.** `transientState=7` (Contact|OnWalkable|Sliding). Every
-  subsequent record (12,292 of them, to the literal end of the file) is
-  byte-identical: same position, same zero velocity, same
-  `transientState=7`.
-
-**Event at idx 3152/3153** is the same shape at a shallower ~18° roof edge
-(`normal≈(0,0.32,0.95)`): the player glides/climbs cleanly along the edge
-for ~140 ticks (idx 3016–3152, gaining ~10 m of Z — this portion is
-healthy behavior), then at idx 3153 horizontal velocity is forced to
-exactly zero in one tick and the position freezes for the rest of the
-examined window.
-
-**Both events are the SAME shape**: a real, correct, non-default collision
-normal is recorded on the landing tick; on the very next tick the mover's
-full horizontal velocity has already vanished and the position never
-changes again. This is what the user experiences as "roof slides no
-longer happen" (symptom b) and "occasional stuck-sliding-on-an-edge"
-(symptom c). Neither event's landing surface is steep by `FloorZ` — both
-are moderate, walkable-by-threshold roof pitches.
-
-## 2. Replay harness
-
-`Issue265SteepSlopeCaptureBisectTests.cs` builds a synthetic
-`PhysicsEngine` containing ONE polygon — the exact real triangle recovered
-from record 3433's `bodyAfter.walkableVertices` — registered via
-`ShadowObjectRegistry`, then replays the EXACT real captured ballistic
-state (position + velocity, record index 3415) forward with real gravity
-at 30 Hz, calling `PhysicsEngine.ResolveWithTransition` every tick exactly
-like `PlayerMovementController` does at the Core boundary. Once the mover
-reports `IsOnGround`, the harness keeps REQUESTING the same forward
-velocity every tick (simulating held input) — this is deliberate: it turns
-the harness from "replay what the live game did" (which trivially
-reproduces the freeze, since the live game's own subsequent inputs were
-already zero — see §4) into "does the physics engine itself allow
-continued advance across this surface," which is the actual question S1
-and S2 bear on.
-
-### 2.1 Harness commissioning (three real bugs found and fixed while building it — kept as code comments)
-
-1. `ShadowObjectRegistry.Register`'s broad-phase culls by distance from
-   `worldPos`. Registering at the literal real-world coordinates (X≈256)
-   while querying at world origin put the polygon ~264 units away — the
-   very first run found **zero collisions at all**. Fixed by re-anchoring
-   the whole synthetic scene (triangle + approach trajectory) at the
-   triangle's centroid.
-2. `CellTransit.BuildShadowCellSet`'s outdoor flood
-   (`CellTransit.AddAllOutsideCells`) treats world position as
-   landblock-local (an anchor-frame convention shared with
-   `Ts4SteepRoofWedgeCaptureTests`/`DoorBugTrajectoryReplayTests`, active
-   whenever `CellGraph.TryGetTerrainOrigin` has no real terrain to
-   consult). The real-world coordinates (X≈256) are outside the valid
-   `[0,192)` per-landblock range even after centroid re-anchoring picked a
-   bad cell id — still zero collisions.
-3. `LandDefs.AdjustToOutside` (inside the flood) **silently re-derives**
-   the actual `(lx,ly)` grid cell from the sphere's real position and
-   corrects a mismatched seed rather than honoring the literal
-   `seedCellId` passed to `Register` — an arbitrary chosen cell id
-   (`0x00000011`) registered successfully (`TotalRegistered=1`) but
-   `GetObjectsInCell(0x00000011)` came back empty; the entity had actually
-   landed in cell `0x00000001` (the canonical grid-(0,0) cell, matching
-   the re-anchored centroid). Switching the harness's cell id to
-   `0x00000001` fixed it.
-
-These are documented in the test file's code comments in case another
-harness hits the same three traps.
-
-## 3. A/B outcomes
-
-### (i) HEAD vs (ii) S1-reverted
-
-The S1 revert (`BSPQuery.cs`'s `hasSphere1` branch restored to the
-pre-`db2889af` steepness-gated dual path, mirroring the still-current
-`sphere0` branch — applied locally, verified `git diff --stat` clean
-before and after, never committed) produced **byte-identical output** to
-HEAD for the full 80-tick replay: same landing tick (19), same clean
-44-tick glide (ticks 20–62, `adv=0.5149` every tick, `cnv=false`), same
-freeze at tick 63 (`adv=0.0000` for 16+ consecutive ticks, capped by the
-harness's tick budget — it would continue indefinitely), same recorded
-`collisionNormal=(-0.958,0.128,0.256)` from that point on.
-
-**Why they're identical — confirmed by diagnostic instrumentation**
-(`PhysicsDiagnostics.ProbeIndoorBspEnabled`/`ProbeBuildingEnabled`, the
-`[path-dispatch]`/`[path5-diag]` probes `db2889af` itself added): across
-the entire 80-tick replay, **`hit1=True` never appears once.** The two
-`[path-dispatch] ... collide=True ... contact=False ...` lines (Path 6
-firing during the airborne approach) are followed by
-`insertType=Placement` (Phase 3's walkable-landing retry succeeding) —
-this is the STILL-UNCHANGED `sphere0` (foot) branch's graceful
-`SetCollide`→`Adjusted`→Phase-3-Placement chain, not the `hasSphere1`
-branch S1 touched. Once grounded, every subsequent Path-5 dispatch reports
-`hit0=False hitPoly0=False` then `hit1=False hitPoly1=False` — a genuinely
-clean glide with no collision at all, which is why the S1 edit (which only
-fires inside `if (hit1 || hitPoly1 is not null)`) never executes for this
-trajectory. **S1's site is provably unreached by the real mined
-trajectory that produced the freeze.** Reverting code that never runs
-cannot change the outcome — this is not a coincidence, it's the direct
-mechanical explanation.
-
-### (iii) S2 toggle
-
-**Not run as a harness A/B — proven inert by static analysis instead.**
-`grep -rn "\.calc_friction(" src/` returns **zero production call sites** —
-the only callers of `PhysicsBody.calc_friction` in the entire repository
-are its own unit tests (`tests/AcDream.Core.Tests/Physics/PhysicsBodyTests.cs`).
-`PlayerMovementController.cs` mentions it only in a code comment
-(line ~2021, "friction next frame") — it is never invoked. Neither
-`ResolveWithTransition` nor `PlayerMovementController`'s tick loop calls
-`calc_friction` anywhere. **S2's threshold value (0.0 vs 0.25) cannot
-affect any live or replayed behavior, full stop** — there is no toggle to
-run because there is no live code path to toggle.
-
-### (iv) Both reverted
-
-Follows immediately from (ii) and (iii): with S1 reverted producing
-byte-identical output to HEAD, and S2 provably inert, the "both" variant
-is mathematically identical to (ii), which is identical to (i). No
-separate run was needed.
-
-### A/B summary table
-
-| Variant | Landing tick | Clean glide (ticks 20-62) | Freeze at tick 63+ | Notes |
-|---|---|---|---|---|
-| (i) HEAD | 19 | yes, `adv=0.5149`/tick | yes, frozen forever | `hit1` never true |
-| (ii) S1 reverted | 19 (identical) | yes (identical) | yes (identical) | S1's branch unreached |
-| (iii) S2 toggle | n/a | n/a | n/a | dead code, no call sites |
-| (iv) both | 19 (identical) | yes (identical) | yes (identical) | follows from (ii)+(iii) |
-
-## 4. The actual mechanism (found by hand-tracing the live capture against `PlayerMovementController.cs`, independently confirming it explains BOTH mined freeze events exactly)
-
-Neither S1 nor S2 touch velocity. The full-zero-in-one-tick signature
-(§1.2) is produced by two pre-existing, Campaign-P-independent pieces
-working in sequence:
-
-1. **The landing tick** (`PlayerMovementController.cs`, the
-   `if (resolveResult.IsOnGround && _body.Velocity.Z <= 0f)` block):
-   Contact+OnWalkable are set, and — because `Velocity.Z < 0` — ONLY the
-   Z component is hand-zeroed: velocity becomes `(11.15, 14.13, 0)`.
-   `PhysicsObjUpdate.HandleAllCollisions` then runs with `shouldReflect =
-   true` (the mover was airborne the frame before: `prevOnWalkable=false`
-   makes `shouldReflect` unconditionally true regardless of the new
-   grounded state — see `PhysicsObjUpdate.cs:163-164`). But
-   `dot(velocity, collisionNormal) = dot((11.15,14.13,0),
-   (0.286,0.429,0.857)) ≈ +9.25` — POSITIVE (moving away from, not into,
-   the surface, because the Z component that would have made it negative
-   was just zeroed) — so the `if (dot < 0f)` reflection guard
-   (`PhysicsObjUpdate.cs:177`) never fires. Velocity survives this tick as
-   `(11.15, 14.13, 0)`.
-2. **The very next tick** (`PlayerMovementController.cs:1868-1882`, added
-   2026-07-20 by `f961d700`, "port retail complete object frame
-   pipeline" — R6, well before Campaign P):
-   ```csharp
-   if (_body.OnWalkable)
-   {
-       float savedWorldVz = _body.Velocity.Z;
-       if (hasAnimationRootMotion)
-       {
-           _body.Velocity = new Vector3(0f, 0f, savedWorldVz);
-       }
-       ...
-   }
-   ```
-   `OnWalkable` is now true (set last tick), so this runs UNCONDITIONALLY,
-   EVERY tick, for as long as the mover stays grounded: it zeros
-   `Velocity.X/Y` to exactly zero (`savedWorldVz` is already 0 from step
-   1), replacing physics-integrated horizontal velocity with
-   animation-root-motion-driven displacement (`pmDelta.Origin`, populated
-   from `_advanceAnimationRootMotion`, which only produces nonzero
-   displacement when a movement key is actually held). **With no key held
-   at the instant of landing, `pmDelta.Origin` stays `Vector3.Zero` forever,
-   and the mover never advances again.** This reproduces `bodyBefore.velocity
-   = (0,0,0)` at record 3434 exactly, and the permanent freeze that follows.
-
-This is the R6 "local player animation-owned grounded movement"
-architecture: once grounded, walking is driven entirely by held-input +
-animation root motion, not by integrating `Velocity`. It has been in
-place since 2026-07-20 — **ten days before Campaign P and the TS-4
-removal/revert (2026-07-29/30)** — and is explicitly a frozen-phase
-architecture per the milestones doc (R6 shipped; the freeze list bars
-rework without a dedicated brainstorm). It is retail-DIVERGENT in one
-specific way that matters here: retail does not need a held key to carry
-residual momentum across a landing — a fast fall onto a walkable-but-
-sloped surface should glide/sled per `docs/ISSUES.md` #166 ("Slope-landing
-glide + bounce absent... acdream lands clean and dead"), which is filed,
-open, and explicitly OUT OF SCOPE for this pass (the `Sledding`
-`PhysicsStateFlags` bit that would let `calc_friction`'s Sledding-gated
-overrides engage is never set anywhere in the codebase — a separate,
-already-tracked gap).
-
-`git log --oneline -3 -- src/AcDream.Core/Physics/PhysicsObjUpdate.cs`
-confirms `HandleAllCollisions` itself was also last touched by an
-unrelated water fix (AP-10, `cc8d57a2`) — Campaign P did not modify it
-either.
-
-## 5. Re-reading the oracle plan's S1 claim against the mined evidence
-
-The task asked specifically: if S1's port is faithful but its SCOPE is
-wrong, say exactly that. Re-checked against
-`docs/research/2026-07-30-ts4-116-oracle-plan.md` §2.3-§2.4 and §3, plus
-this pass's own finding:
-
- **S1's port IS faithful in isolation.** Its cited sources
-  (`acclient_2013_pseudo_c.txt:323824-323834`, ACE `BSPTree.cs:221-230`)
-  are an exact structural match — not a BN misdecompile, not a citation
-  error. This was independently re-verified by reading the current
-  `BSPQuery.cs:2259-2302` against the same two sources again this pass; no
-  discrepancy found.
- **S1's scope is narrower than any symptom this pass could reproduce —
-  not wider.** The oracle plan's own Addendum 2 (§"implementation
-  session") already found this exact pattern once, for the door
-  tick-22760 capture: the hypothesis assumed the "not-yet-in-Contact"
-  branch would fire, but the mover was actually GROUNDED (`Contact` set),
-  so dispatch went to Path 5 instead and S1's site was never reached. This
-  pass finds the SAME pattern a second, independent time, for a
-  DIFFERENT capture (a genuine airborne fall, not a grounded door-push):
-  the foot sphere (`sphere0`) reaches the rising/sloped polygon at the
-  same moment as or before the head sphere, so the `if (hit0 ||
-  hitPoly0 is not null)` branch above `hasSphere1`'s check fires first and
-  RETURNS before `hasSphere1`'s block is ever entered
-  (`BSPQuery.cs:2188` gates the whole `hasSphere1` block behind falling
-  through that first `if`). `hit1=True` never appears once across the
-  entire 80-tick replay, confirming this mechanically, not just by
-  inference.
- **Two independent capture families (a grounded door-push, and now an
-  airborne fall-and-land) both show S1's site going unreached.** This
-  strongly suggests S1's real-world reach is much narrower than its
-  authors worried — for it to matter, a trajectory would need the FOOT
-  sphere to stay clear while the HEAD sphere alone grazes a polygon
-  during an airborne (not-yet-grounded) frame — e.g. jumping up under an
-  overhang, or clipping a roof's underside while airborne with the feet
-  still below the eave line. **Neither of #265's two concrete mined
-  freeze events is that geometry.** S1 remains a real, citable, retail-
-  faithful port-accuracy improvement and should NOT be reverted on this
-  evidence (it fixes a genuine, if narrow, divergence for whenever its
-  exact geometry does occur) — but it is not implicated in the symptoms
-  #265 was filed against.
-
-## 6. Named culprit
-
-**Neither S1 nor S2. This is S3 — but not a NEW regression: it is the
-pre-existing, frozen-phase R6 "grounded movement is animation-root-motion-
-owned" architecture (`PlayerMovementController.cs:1868-1882`, landed
-2026-07-20 via `f961d700`, ten days before Campaign P), which
-unconditionally zeros the mover's horizontal `Velocity` every tick once
-`OnWalkable` is true, with no gate on approach speed, surface steepness,
-or how the mover became grounded.** It was mechanically traced, tick by
-tick, against BOTH of #265's concrete mined freeze events and reproduces
-the observed `(0,0,0)` velocity and permanent position-freeze exactly.
-
-This explains symptom (b) (roof slides don't continue — there is no
-"continue," walking requires a held key that landing doesn't supply) and
-symptom (c) (stuck at the landing spot indefinitely) completely, for both
-mined events. It does **not**, by itself, explain symptom (a) (the
-"bounce" on jumping into an uphill slope) — that is a property of
-`PhysicsObjUpdate.HandleAllCollisions`'s elastic reflection (`shouldReflect
-= true` whenever the mover was NOT already on walkable ground before AND
-after the resolve — `PhysicsObjUpdate.cs:163-164`), which is ALSO
-pre-existing (from the #182 rebuild, well before Campaign P) and fires for
-ANY valid `CollisionNormal` reported while airborne, regardless of which
-BSPQuery branch produced it. This pass did not find or replay a concrete
-"bounce" event in the captures (the closest analogue — the tick-63
-edge-freeze in the replay harness — shows a suspicious secondary normal,
-`(-0.958,0.128,0.256)`, unrelated to the registered polygon's own plane
-normal, with Path-5 diagnostics showing no fresh BSP hit during the frozen
-ticks; this smells like stale `ContactPlane`/`CollisionNormal` persistence
-at a polygon boundary rather than a fresh reflection, and — like the S1
-revert — was unaffected by reverting S1. It is flagged as a genuine open
-question, not resolved this pass, and may be an artifact of this
-harness's single small (24-unit) synthetic triangle rather than a general
-production bug; a real roof's continuous mesh would not present a "run off
-the edge of a 24-unit patch" boundary at all. See §7).
-
-## 7. What's still open (do not guess, per CLAUDE.md)
-
-1. **Why does the user perceive this as a NEW regression coinciding with
-   Campaign P**, if the freeze mechanism (§4) predates it by ten days and
-   is unaffected by S1/S2? Two honest hypotheses, neither confirmed:
-   (a) the roof-jump/fall scenario was specifically exercised for the
-   FIRST time as part of the Campaign P visual matrix (scenarios 4/5),
-   surfacing a pre-existing bug rather than a new one; (b) a genuinely
-   separate, not-yet-isolated interaction exists. Resolving this needs
-   either a live retail-vs-acdream side-by-side of the EXACT same
-   fall-and-land-with-no-input scenario pre-Campaign-P (to confirm the
-   freeze is not new), or a fresh capture of the user's ACTUAL "roof
-   slide" repro (holding a movement key throughout, not a passive fall) to
-   see whether the animation-root-motion path (which DOES produce
-   displacement while a key is held) also fails.
-2. **The tick-63 edge freeze** in this pass's own harness (§6, closing
-   parenthetical) — a `CollisionNormal` unrelated to the registered
-   polygon's plane, reported while Path-5 diagnostics show no fresh hit.
-   Candidate next step: extend the harness's synthetic roof to several
-   contiguous polygons (removing the small-triangle-edge artifact) and
-   re-run; if the freeze persists on a much larger interior region, it is
-   a real, separate, third mechanism worth its own root-cause pass
-   (possibly `SpherePath.PrecipiceSlide`'s edge-crossing test, or stale
-   `LastKnownContactPlane` persistence — NOT yet confirmed, do not guess
-   further).
-3. **Symptom (a)'s bounce** was analyzed only by static code reading
-   (`HandleAllCollisions`'s reflection math), not independently reproduced
-   against a live-captured bounce event — none of the 38
-   `collisionNormalValid=true` records in session2 showed the "airborne,
-   then a large upward `Velocity.Z` jump next tick" signature this pass's
-   Signature-A scanner looked for. A fresh capture specifically of a
-   jump-into-an-upward-slope repro (ideally with `ACDREAM_PROBE_RESOLVE=1`
-   or `ACDREAM_CAPTURE_RESOLVE` active for the WHOLE approach, not just
-   the moment of impact) would let Signature A actually fire and give a
-   concrete oracle the way records 3433/3434 did for the freeze.
-
-## 8. Recommended fix direction
-
-**Do not touch S1** (`BSPQuery.cs`'s `hasSphere1` branch) — it is a real,
-narrow, retail-faithful improvement unrelated to #265's two concrete mined
-events; reverting it would only reopen the #116 shape-1 door-collision gap
-it was written to close, for zero benefit here.
-
-**Do not spend further effort on S2** (`calc_friction`'s threshold) until
-it is actually wired into a live code path — right now changing it changes
-nothing observable, in either direction. If/when `calc_friction` IS wired
-into `PlayerMovementController` (a legitimate future piece of closing #166,
-the downhill-sled issue), the 0.25 threshold becomes live and worth
-re-testing at that point, not before.
-
-**The real target is #166 + the grounded-movement architecture (§4/§6),
-which is a frozen-phase design question, not a quick fix.** Per CLAUDE.md's
-"the roadmap and the observed bug disagree → brainstorm before writing
-code" rule, this needs `superpowers:brainstorming` before any
-implementation: does acdream want a genuine physics-driven momentum carry
-across a landing (porting the retail `Sledding` state + a real
-`calc_friction` wiring), or a narrower "if IsOnGround at high incoming
-speed, force a minimum coast distance regardless of held input" patch? The
-former is retail-faithful and already has a filed target (#166); the
-latter would be a new, unfiled design decision. Either way, this is
-explicitly NOT an S1/S2 code change — it is new work against
-`PlayerMovementController.cs`'s grounded-movement block and
-`PhysicsBody.calc_friction`'s wiring, gated on a design conversation, not a
-revert.
-
-## 9. As-fixed addendum (2026-07-30, same day — implementation session)
-
-The user chose the retail-faithful direction (§8's first option): port the
-genuine physics-driven momentum carry, wiring `calc_friction` for real
-rather than adding a narrower coast-distance patch. Implementation
-landed the same day as this bisect.
-
-### 9.1 The fix
-
-Two changes, both minimal and at the exact commit points already
-responsible for the adjacent state:
-
-1. **`src/AcDream.Core/Physics/PhysicsEngine.cs`** — `body.GroundNormal`
-   (the vector `calc_friction` dots velocity against, per its own doc
-   comment "`angle = dot(velocity, contactPlane.N)`") had **zero
-   production writers anywhere** before this fix; it silently defaulted
-   to `Vector3.UnitZ` forever (`grep -rn "GroundNormal\s*=" src/` found
-   only the property's own default and calc_friction's internal reads/
-   writes). This is a SEPARATE gap from the one §4 found — even if
-   Velocity had survived the grounded-tick zero, friction would have
-   dotted it against a fake flat-ground normal on any real slope,
-   producing wrong physics. Fixed by syncing
-   `body.GroundNormal = ci.ContactPlane.Normal` (or
-   `ci.LastKnownContactPlane.Normal`) at the exact block
-   (`PhysicsEngine.cs` ~:1297-1320) that already publishes
-   `body.ContactPlane`/`ContactPlaneValid` after every resolve — Core-level,
-   so player, remote, ordinary, and projectile movers all get a real
-   slope normal for free (matching the task's "the mechanism is general"
-   requirement; the ordinary/remote physics updaters
-   (`RuntimeOrdinaryPhysicsUpdater.cs`, `RuntimeRemotePhysicsUpdater.cs`)
-   already compose root motion + `UpdatePhysicsInternal` cleanly, with no
-   destructive zero — this fix brings the player path in line with its
-   own siblings, not a novel invention).
-
-2. **`src/AcDream.Runtime/Gameplay/PlayerMovementController.cs`** — the
-   grounded-tick block §4 identified (`if (_body.OnWalkable) { ... if
-   (hasAnimationRootMotion) _body.Velocity = new Vector3(0f, 0f,
-   savedWorldVz); ... }`) no longer reconstructs `Velocity` AT ALL for the
-   `hasAnimationRootMotion` case (production graphical local-player
-   path). The condition is now `if (_body.OnWalkable &&
-   !hasAnimationRootMotion)`, so ONLY the headless/test-controller
-   `get_state_velocity` fallback (unchanged) still writes velocity here.
-   Root motion continues to fully own commanded locomotion (walking
-   displacement still comes from `pmDelta.Origin`, never from
-   `Velocity`) — this does not reintroduce command- or packet-cadence-
-   derived grounded translation (the DO-NOT-RETRY rule in
-   `claude-memory/project_physics_collision_digest.md`); it only stops
-   DESTROYING whatever `Velocity` already holds. The existing
-   `preIntegratePos`/`postIntegratePos` bracketing (root-motion apply,
-   then `calc_acceleration()` + `UpdatePhysicsInternal(tickDt)`, then
-   `ResolveWithTransition(preIntegratePos, postIntegratePos, ...)`) was
-   ALREADY structurally correct for composing both channels — retail's
-   `CPhysicsObj::UpdatePositionInternal` composition model — so no
-   further restructuring was needed once the destructive zero was
-   removed.
-
-### 9.2 Fixture results (freeze → slide, proven)
-
-`Issue265SteepSlopeCaptureBisectTests.cs` gained a `ComposedTickSample`
-harness (`ReplayRealRoofLandingComposed`) that mirrors
-`PlayerMovementController.cs`'s per-tick composition line-for-line using
-only Core types (`PhysicsBody`, `PhysicsObjUpdate.HandleAllCollisions`,
-`PhysicsEngine`), parameterized by a
-`preserveResidualVelocityOnGroundedTick` toggle representing the old vs.
-new shape:
-
- **`ComposedRoofLanding_OldZeroingModel_ReproducesTheMinedFreeze`**
-  (toggle `false`): reproduces the exact mined signature — velocity forced
-  to `(0,0,0)` the tick after landing, frozen solid (`FrozenStreak` grows
-  unbounded) for the rest of the replay.
- **`ComposedRoofLanding_NewFix_VelocitySurvivesAndPositionKeepsAdvancing`**
-  (toggle `true`): the SAME captured landing (velocity `(11.15, 14.13,
-  -23.14)` onto the real `(2,3,6)/7` roof normal) now survives the Z-only
-  hand-zero with its full horizontal speed, and the position advances
-  every single tick (`adv=0.5149` per tick, `onWalk=true`, `frozen=0`)
-  for the entire post-landing window — a genuine sustained glide, not a
-  freeze. (The original small real-captured triangle had to be enlarged
-  6x about its centroid — same plane, same normal, same landing point/tick,
-  see `MakeRoofEngine`'s new `scale` parameter — because the real glide
-  travels ~50 m over the test window and would otherwise run off the
-  tiny real triangle's edge into the SEPARATE small-triangle-boundary
-  artifact §7 item 2 already flagged; that artifact is confirmed
-  real and unrelated to this fix, see §9.4.)
- **`ComposedRoofLanding_NewFix_SyntheticGrazingApproach_DecaysViaCalcFriction`**:
-  a synthetic variant (same roof polygon, a deliberately different
-  approach velocity chosen so `dot(velocity, GroundNormal) < 0.25` after
-  landing) proves genuine exponential decay: speed at landing ≈ 6.0 m/s
-  decays tick-by-tick down to the `SmallVelocitySquared` hard-zero floor
-  by roughly tick 33 after landing — retail's `calc_friction` formula
-  working exactly as ported.
-
-**Important nuance:** the REAL captured landing (record 3433's velocity
-and normal) happens to fall in retail's "moving away fast enough, no
-friction" band (`dot(velocity, GroundNormal) ≈ +9.25 ≥ 0.25`) — so it
-glides at CONSTANT velocity across the roof rather than visibly decaying.
-This is not a bug; retail's own `calc_friction` early-returns in exactly
-this case (the velocity's horizontal projection points "downhill," same
-direction as the normal's horizontal projection — see the derivation in
-§9.3). The task's framing ("decays over subsequent ticks") is
-demonstrated by the separate synthetic case above, which deliberately
-selects a velocity/normal pairing where retail's own formula calls for
-decay; the real mined case demonstrates the OTHER correct retail outcome
-(sustained glide) for its own geometry. Both are "survives and slides,"
-never "freezes" — the actual acceptance bar.
-
-### 9.3 Downhill direction derivation (for the synthetic decay case)
-
-For a planar triangle with outward normal N and any point P on the
-plane, `dot(N, P - centroid) = 0` (coplanarity). For a slope where Z
-increases as you move "uphill," the outward normal's horizontal
-projection points toward LOWER Z (downhill) — e.g. plane `z = m·x`
-(uphill as x increases) has normal `∝ (-m, 0, 1)`, whose horizontal
-component `-m` points toward decreasing x (downhill). The real captured
-roof normal `(0.2857, 0.4286, 0.8571)` has horizontal projection
-`(0.2857, 0.4286)` pointing downhill; the captured velocity's horizontal
-component `(11.15, 14.13)` points in nearly the same direction (both
-positive, roughly proportional) — i.e. the mover is genuinely sliding
-DOWN and AWAY from the impact point, which is exactly why
-`dot(velocity, normal)` comes out strongly positive and friction
-correctly declines to engage.
-
-### 9.4 Runtime-level regression tests + a second, unrelated mechanism found
-
-`tests/AcDream.Runtime.Tests/Gameplay/PlayerMovementControllerTests.cs`
-gained two tests exercising the REAL `PlayerMovementController` (not just
-the Core-level model):
-
- **`Update_AnimationRootMotion_WalkSpeedUnaffectedByResidualVelocityFix`**:
-  ordinary root-motion walking (no fall/collision in flight) advances by
-  exactly the authored per-tick delta for 30 ticks and `BodyVelocity`
-  stays exactly zero throughout — confirming the fix is a complete no-op
-  for the common "just walking around" case, pinning the L.3c hazard
-  (`claude-memory/project_physics_collision_digest.md`'s DO-NOT-RETRY
-  table) at the Runtime level in addition to the existing
-  `GroundedRootMotion_FrictionThreshold_DoesNotHammerLocomotionTests`
-  Core-level pin (unmodified, still green).
- **`Update_RunningJumpLandsOnFlatGround_ResidualVelocitySurvivesAndDecays_NotFrozen`**:
-  a real charged running jump (forward + jump, full production dispatch)
-  lands on flat ground and its residual horizontal speed survives the
-  first post-landing tick, then measurably decays (flat ground:
-  `dot(velocity, (0,0,1)) ≈ 0 < 0.25`, so friction DOES engage here,
-  unlike the real roof capture above).
-
-**Building this test surfaced a second, genuinely separate,
-already-registered mechanism** (temporary `Console.WriteLine`
-instrumentation was added and fully removed per CLAUDE.md's diagnostic-
-logging discipline): `MotionInterpreter.LeaveGround()`
-(`CMotionInterp::LeaveGround` 0x00528b00, R3-W4/J7/J8, unrelated to
-#265/#166) recomputes and OVERWRITES `PhysicsObj.Velocity` from
-`GetLeaveGroundVelocity()` on the grounded→airborne edge, using whatever
-forward command is interpreted AT THAT EXACT TICK — a real, intentional,
-already-ported retail behavior. Releasing the forward key in the SAME
-tick this edge fires (an early test-construction mistake, not a
-production concern) clobbers the just-launched velocity. Separately,
-`MotionInterpreter.ApplyCurrentMovementInterpreted`'s AP-77
-"animation-less/headless movement fallback" (register row AP-77,
-already correctly scoped: "When `MotionInterpreter.DefaultSink` or the
-local PartArray callback is absent...") ALSO rewrites grounded velocity
-from `get_state_velocity()` on every `HitGround`/`LeaveGround` re-apply
-when no `DefaultSink` is wired — which is exactly the state of a
-`PlayerMovementController` built directly in a unit test without wiring
-one. Production (`GameWindow`) always wires a real `DefaultSink`, so
-neither mechanism is live there; the fixed test (1) holds Forward for one
-extra tick so `LeaveGround`'s one-time recompute captures the real
-launch velocity before releasing it, and (2) wires a minimal
-`FakeAnimationDispatchSink` as `controller.Motion.DefaultSink` so
-`ApplyCurrentMovementInterpreted` takes its real dispatch branch instead
-of the AP-77 fallback — making the test representative of the production
-graphical path rather than the headless one. **Neither mechanism
-required any production code change or register update** — AP-77's row
-already accurately describes its scope, and `LeaveGround`'s behavior is
-intentional retail-ported behavior, not a bug this task touches.
-
-### 9.5 Symptom (a), the uphill bounce — confirmed separate, unaffected
-
-Re-derived `PhysicsObjUpdate.HandleAllCollisions`'s `shouldReflect` gate
-byte-for-byte against the raw retail decomp
-(`acclient_2013_pseudo_c.txt:282647-282760`,
-`CPhysicsObj::handle_all_collisions`) this session:
-`var_10_1` (== `shouldReflect`) ends up `!(arg4 && (transient_state & 2)
-!= 0 && !sledding)` where `arg4` is `prevContact`/`prevOnWalkable`
-captured at `SetPositionInternal` entry (before this call's own commits)
-and `transient_state & 2` is read live inside `handle_all_collisions`
-itself — i.e. AFTER `set_on_walkable` has already committed the
-DESTINATION's OnWalkable bit. This is **exactly** `PhysicsObjUpdate.
-HandleAllCollisions`'s existing `shouldReflect = !(prevOnWalkable &&
-nowOnWalkable && !sledding)` — a byte-exact port, not a translation bug.
-For ANY fresh landing from airborne (`prevOnWalkable=false`), retail
-itself reflects whenever the collision normal shows "moving into the
-surface" (`dot < 0`), REGARDLESS of whether the destination is walkable.
-This is the SAME mechanism AD-25 closed (2026-07-30, Campaign P Slice
-P3, docs/ISSUES.md #166) for both local and remote movers — confirmed
-pre-existing and out of scope for this task, matching CLAUDE.md's "do
-not fix code that matches retail" rule.
-
-`UphillLanding_Synthetic_ReflectionDecisionUnaffectedByResidualVelocityFix`
-(`Issue265SteepSlopeCaptureBisectTests.cs`) constructs a synthetic
-30°-uphill walkable slope, a falling-forward approach with `dot(velocity,
-normal) < 0` by construction, and runs `HandleAllCollisions` with and
-without the residual-velocity-preserving toggle applied AFTERWARD. The
-reflection decision (and its resulting velocity) is identical either way
-— proving the #265/#166 fix is orthogonal to whatever
-`HandleAllCollisions` decides, not a cause of or a fix for the bounce.
-The test's own log line documents the specific synthetic case DOES
-reflect (`Vz` goes from `0` to `+2.27` on this exact input), consistent
-with retail's byte-exact algorithm — evidence for a future dedicated pass
-if the user's live repro still shows an unwanted bounce, not a verdict
-this task renders.
-
-### 9.6 Test/file summary
-
- `src/AcDream.Core/Physics/PhysicsEngine.cs` — `GroundNormal` sync.
- `src/AcDream.Runtime/Gameplay/PlayerMovementController.cs` — grounded
-  block no longer zeros `Velocity` for the animation-root-motion case.
- `tests/AcDream.Core.Tests/Physics/Issue265SteepSlopeCaptureBisectTests.cs` —
-  `MakeRoofEngine`'s new `scale` parameter, `ComposedTickSample` +
-  `ReplayRealRoofLandingComposed`, and four new `[Fact]`s (old-model
-  freeze pin, new-fix slide proof, synthetic decay proof, uphill-bounce
-  orthogonality proof).
- `tests/AcDream.Runtime.Tests/Gameplay/PlayerMovementControllerTests.cs` —
-  `FakeAnimationDispatchSink` + two new `[Fact]`s (walk-speed no-op pin,
-  real running-jump landing survival+decay pin).
- `docs/ISSUES.md` — #265 and #166 updated (fix implemented, closure
-  pends the user's visual-gate acceptance).
- `docs/architecture/retail-divergence-register.md` — AP-7's retirement
-  note corrected (the 0.25f threshold port was always right; it had
-  nothing real to operate on until this fix closed both the grounded-
-  velocity-zero and the `GroundNormal`-wiring gaps). No new row filed —
-  this change ports retail's mechanism faithfully; it does not introduce
-  a new deviation.

-# Animation system parity audit — retail vs acdream (2026-07-30)
-
-**Status: COMPLETE — report-only investigation, no code changes made.**
-
-Scope: `CMotionInterp` / `CSequence` / `MotionTableManager` / `CMotionTable`
-retail method surfaces vs acdream's `src/AcDream.Core/Physics/MotionInterpreter.cs`,
-`src/AcDream.Core/Physics/Motion/*`, `src/AcDream.Core/Physics/AnimationSequencer.cs`,
-`src/AcDream.App/Rendering/Vfx/AnimationHookFrameQueue.cs`.
-
-**Bottom line:** the core animation-selection/playback stack
-(`MotionInterpreter`/`CSequence`/`CMotionTable`/`MotionTableManager`) is a
-faithful, heavily retail-cited port. All 103 symbols.json-listed retail
-methods across the four classes were enumerated (section 1); only one is a
-genuine unexplained gap (`get_adjusted_max_speed`) and the rest of the
-"unported" set is verified dead code in retail itself. All 7 traced
-feel-visible flows (section 2) came back parity. The real, actionable gaps
-are narrow and listed in section 6's ranked catalog: an animated-emote
-authoring gap (AD-57), two already-known hook-timing residuals (TS-50/
-TS-51) precisely rescoped against current code, one likely-already-fixed
-issue (#64) needing only live re-verification, and two untraced
-combat/casting-layer questions flagged for a future audit outside this
-scope.
-
-## Note on the requested prior deep-dive doc
-
-The task referenced `docs/research/2026-06-04-animation-sequencer-deep-dive.md`
-as prior art. That file does not exist in this worktree or anywhere in git
-history (`git log --all --diff-filter=A -- "*animation-sequencer-deep-dive*"`
-returns nothing). `claude-memory/MEMORY.md` indexes it, and a same-named
-**skill** (`acdream-animation-sequencer-deep-dive`) exists that would
-presumably generate such a doc, but no prior run's output is present at that
-path or any other. The closest prior-art documents actually in the repo are:
- `docs/research/2026-06-26-movement-animation-retail-parity-audit.md` (D1-D12
-  divergence list, dated before the R6/J-slice root-motion work — most of its
-  wire-format findings, D1/D3/D4/D9, have likely since been superseded by
-  TS-33/TS-47 and the R6 root-motion campaign; treated as historical baseline
-  only, re-verified against current code below, not trusted at face value)
- `docs/research/acclient_animation_map.md`, `docs/research/acclient_animation_pseudocode.md`
- `docs/research/2026-04-21-animation-audit.md`, `docs/research/2026-04-28-combat-animation-planner.md`
- `docs/research/2026-07-02-r1-csequence/r1-acdream-sequencer.md`
- `docs/research/2026-07-02-inbound-motion-verbatim-port-handoff.md`
-
-This audit proceeds using those plus the R6 sections of
-`claude-memory/project_physics_collision_digest.md` (which describes what R6
-already shipped — not re-audited here per task instructions) and a fresh
-grep sweep of the named retail decomp.
-
---
-
-## 1. Method-coverage sweep
-
-Two independent passes fed this section: a dedicated method-coverage-sweep
-sub-agent did a symbol-by-symbol enumeration against `symbols.json` +
-pseudo-C call-site tracing, and the lead auditor separately read essentially
-the entirety of all four files directly (`MotionInterpreter.cs` ~2,600 of
-3,182 lines read in full, `CSequence.cs`/`CMotionTable.cs`/`MotionState.cs`/
-`AnimationSequencer.cs` read in full) and independently confirmed the
-sub-agent's headline finding (`GetMaxSpeed()` is the only max-speed accessor
-anywhere in the App/Runtime call sites — `grep` for `AdjustedMaxSpeed`/
-`get_adjusted_max_speed` across `src/` returns zero hits outside the doc
-comment that names it as unported). The two passes agree; findings below are
-merged, with the sub-agent's table format preserved since it's more scannable
-than prose.
-
-**Methodology note (symbol-artifact class):** `symbols.json` occasionally
-attributes a class method name to an address whose pseudo-C body is a
-different, unrelated function, or lists two names at the identical address
-(most likely `/OPT:ICF` identical-code-folding at link time collapsing
-byte-identical trivial bodies, with the PDB keeping multiple aliases for one
-surviving address). Confirmed instances: `CMotionInterp::HandleEnterWorld`
-@ `0x00694750` resolves to `IDClass<>::~IDClass` (unrelated template
-destructor); `CMotionInterp::InqStyle` @ `0x00527B10` resolves to
-`CBaseFilter::GetPinVersion` (unrelated DirectShow class); `MotionTableManager::RemoveLinkAnimations`
-and `HandleEnterWorld` are both listed at `0x0051BDD0` (only one body exists
-there); `CMotionTable::Allocator`/`Allocate` are both listed at `0x004F96E0`.
-These are marked **SYMBOL-ARTIFACT** below rather than forced into
-ported/unported, since the decomp genuinely cannot answer what (if anything)
-that distinct method does.
-
-Also confirmed independently on both classes that have a `Pack`/`UnPack`
-family (`CSequence`, `CMotionTable`): these `PackObj`/`DBObj` serialization
-methods have **zero call sites anywhere in the 1.4M-line pseudo-C** outside
-their own bodies and a `.rdata` vtable-slot registration — dead code
-inherited from a shared server/client engine base, never invoked by the
-retail client itself. Their absence in acdream is correctly not a gap.

-symbol-artifacts (not real distinct methods), ~9 trivial/GC-obviated, 1
-architecturally superseded, 1 ported-but-uncited (`CMotionInterp.Create`),
-and 8 genuinely unported — of which 7 are verified dead code in the retail
-client itself (the `Pack`/`UnPack`/`pack_size`/`GetMotionTableID`/
-`SetMotionTableID` family, confirmed via call-site tracing). **The single
-genuine, unexplained, feel-visible-risk gap across all four classes is
-`CMotionInterp::get_adjusted_max_speed` (0x00527D00)** — the only unported
-method sitting on a hot per-tick gameplay path (dead-reckoning catch-up
-speed clamp) whose retail selection condition could not be resolved from
-static analysis alone. All four files hold up as genuinely faithful,
-well-cited retail ports; this sweep found no evidence of silently-diverged
-gameplay logic in any of the four classes' core responsibilities.
-
-## 2. Feel-visible flow verdicts
-
-This section was independently traced by the lead audit against the primary
-source (the extensively retail-cited C# in `CMotionTable.cs`, `CSequence.cs`,
-`MotionState.cs`, `AnimationSequencer.cs`, `MotionInterpreter.cs` — most
-methods in these five files quote the exact decompiled C body in a doc
-comment, so this section cites the acdream file:line as primary evidence
-rather than re-deriving from the 1.4M-line decomp text directly; the
-background method-coverage-sweep and flow-tracing agents' independent
-findings are merged in below where they add or contest something). A
-striking finding up front: several of the 7 flows below turned out to have
-**verdict parity for a decisive reason that ISN'T "acdream ported it
-correctly"** — retail itself doesn't do the fancier thing the flow's framing
-implied. That distinction matters for a retail-faithful project: it means
-there is nothing to build, not merely nothing left to fix.
-
-**1. Stance-change transition animations — PARITY.**
-`CMotionTable.GetObjectSequence` Branch 1 (`src/AcDream.Core/Physics/Motion/CMotionTable.cs:279-336`,
-citing retail `GetObjectSequence @ 0x00522860`) is a full style-change
-dispatcher: it computes an exit link from the current substate to the
-current style's default substate, a direct link from the current style's
-default substate to the target style's default substate, and — when no
-direct link exists — a double-hop through the table's `DefaultStyle` (lines
-308-314), then plays exit-link → hop1 → hop2 → new-cycle in sequence
-(`AddMotion` calls at 318-321) before installing the new style/substate.
-This is retail's genuine weapon-draw/style-change link mechanism, not a
-simplified instant cut. `AnimationSequencer.SetCycle`
-(`src/AcDream.Core/Physics/AnimationSequencer.cs:390-391`) drives style
-changes through exactly this path before dispatching the target motion.
-
-**2. Landing after jump/fall (soft vs hard landing) — PARITY, and the "gap"
-doesn't exist in retail.** `MotionInterpreter.HitGround`
-(`src/AcDream.Core/Physics/MotionInterpreter.cs:2425-2443`) quotes retail's
-`CMotionInterp::HitGround @ 0x00528ac0` FULL BODY: strip link animations,
-then re-apply the PRESERVED pre-fall interpreted forward command (walk/run/
-ready) — there is no velocity, fall-distance, or fall-duration branch
-anywhere in that function. Retail's `Falling` SubState
-(`MotionInterpreter.cs:56-63`) is one airborne cycle regardless of how far
-the body fell; landing is simply "the Falling→X link fires through the same
-`GetObjectSequence` Branch 2 cycle-to-cycle mechanism verified in item 6."
-There is no severity-based "hard landing" animation to select in retail's
-own Humanoid MotionTable, so this was never a divergence to close.
-
-**3. In-place turn cycles vs omega-driven turning — PARITY (already shipped
-under R6; not re-audited here per task scope, confirmed only that the two
-things are the SAME mechanism, not competing ones).** `TurnRight`/`TurnLeft`
-(`0x6500000D`/`0x6500000E`) carry the `0x40000000` cycle-class bit
-(`0x65000000 & 0x40000000 != 0`), so they ARE genuine `CMotionTable` cycles
-with their own authored `Anims` (the visual leg-crossing/pivot animation)
-AND their own authored `Omega` (R6's pinned finding: `omega.Z = -1.5`
-rad/s ≈ -86°/s from the installed Humanoid table, not a synthetic 90°
-formula). `CMotionTable.AddMotion`
-(`src/AcDream.Core/Physics/Motion/CMotionTable.cs:116-134`) writes both the
-anim frames and the omega from the SAME `MotionData` record onto the
-sequence in one call; `CSequence.ApplyPhysics` rotates the Frame by that
-omega every frame the turn cycle plays. There was never a separate
-"visual cycle vs physical rotation" question to resolve — one MotionData
-record drives both.
-
-**4. Walk↔run mid-stride transitions — PARITY (same Branch-2 machinery as
-item 1, one level down).** Walk and Run are both cycle-class substates
-within `NonCombat`/combat styles, so crossing the walk/run threshold or
-toggling the Run hold-key is a same-style cycle-to-cycle request through
-`GetObjectSequence` Branch 2 (`CMotionTable.cs:341-423`): it looks up a
-direct link between the two substates via `GetLink`, falls back to a
-style-default double-hop if none exists (lines 378-383), and has a
-same-substate "fast re-speed" path (lines 358-367) for a pure speed change
-within the SAME substate (e.g. accelerating while already running) that
-rescales the cyclic framerate and physics in place rather than re-triggering
-a full transition. This is retail's genuine walk-to-run link/blend
-mechanism, not an instant swap.
-
-**5. Backward/strafe cycle selection — PARITY, and again the "gap" doesn't
-exist in retail.** `AnimationSequencer.SetCycle`
-(`src/AcDream.Core/Physics/AnimationSequencer.cs:344-348, 367-381`) states
-plainly, citing ACE's `MotionInterp.cs:394-428` as cross-check: "the AC
-MotionTable has NO cycles for TurnLeft, SideStepLeft, or WalkBackward. These
-are played as their right-side/forward equivalents with a negated
-framerate so the animation runs in reverse." This is a retail asset-content
-fact, not an acdream simplification — there is no distinct backward-walk or
-strafe-left animation to select in the first place; retail itself reverses
-the forward/right cycle. acdream's remap (WalkBackward → WalkForward at
-0.65×speed, SideStepLeft → SideStepRight at -1×speed) matches this exactly
-at both the `AnimationSequencer` boundary (local-player raw input) and the
-`MotionInterpreter.adjust_motion` boundary (wire-level, R3-cited) — see
-section 1's method sweep for whether both call sites are still needed or
-one is now dead code.
-
-**6. Link-animation traversal system — PARITY, and it is the single most
-load-bearing finding of this audit.** `CMotionTable.GetLink`
-(`CMotionTable.cs:190-241`, retail `get_link @ 0x00522710`) is a genuine,
-general-purpose `(fromStyle, fromSubstate, toSubstate)` link lookup over the
-DAT-authored `Links` dictionary — not a hardcoded Ready/Walk/Run subset. It
-handles the forward direction, a reversed-key direction (used when a speed
-sign flip means "the link is authored the other way," e.g. the Ready↔
-WalkBackward case the doc comment says was field-validated fixing a
-"left leg twitches" glitch), and a style-level catch-all fallback. Every one
-of `GetObjectSequence`'s four branches (style-change, cycle, action,
-modifier) calls it and composes the result into 1-3 chained `AddMotion`
-calls (exit link, direct/hop1, hop2) before the target cycle, exactly
-matching retail's own double-hop-via-`DefaultStyle` fallback for style
-changes with no direct link, and an out-hop/action-link/return-hop triple
-for action-class motions with no direct link to the target (`CMotionTable.cs:428-478`,
-with the load-bearing `#A4-1` tick-count citation: "never the base cycle,
-never double-counted (ACE's bug, not retail's)" — i.e. acdream's tick
-accounting is MORE correct than the reference ACE port here, not less).
-This resolves the audit's biggest open question going in: acdream does not
-skip genuine style-to-style links (drawing a weapon, sheathing, sitting
-down) in favor of a hardcoded locomotion-only subset.
-
-**7. Interrupted-animation behavior — PARITY at the queue-mechanics level;
-one narrower residual question outside this file set.** A dedicated
-flow-tracing sub-agent (independent pass, cross-checked against ACE) closed
-most of the uncertainty this item started with. Retail
-`MotionTableManager::RemoveRedundantLinks` (`0x0051bf20`) explicitly only
-collapses cycle-class-not-modifier or style-class queue tails — the
-modifier/action-class branch is "neither branch taken" (confirmed directly
-in `CMotionTable.cs`'s ported `RemoveRedundantLinks`, see section 1): action-class
-one-shots (attacks, casts) are **never truncated** by this mechanism and
-always run their tick-countdown to natural completion. Separately, retail
-`CPhysicsObj::interrupt_current_movement` (`0x005101f0`) is called
-unconditionally from `jump()` and cancels an in-flight `MoveToManager`
-transition — a wholly different mechanism from the action queue, not a
-"cancel this attack" primitive. acdream's `MotionTableManager.RemoveRedundantLinks`
-(`src/AcDream.Core/Physics/Motion/MotionTableManager.cs:191-248`) is a
-byte-for-byte match including the identical `0xb0000000`/`0x70000000` block
-masks and the same fallthrough, and the `InterruptCurrentMovement` seam
-(`MotionInterpreter.cs:658`) is fully wired in PRODUCTION — not a stub — to
-real `MoveToManager.CancelMoveTo(WeenieError.ActionCancelled)` in both
-`src/AcDream.App/Physics/LiveEntityMotionRuntimeController.cs:152-154`
-(remote) and `src/AcDream.App/Input/PlayerModeController.cs:354-362` (local
-player), plus 4 call sites in `StickyManager.cs`. **Net: attack/cast
-animations are uninterruptible by movement/jump input in BOTH clients —
-movement just queues behind them; jump only ever cancels an in-flight
-move-to, never the action queue.** The one thing this audit still did not
-verify: whether higher-level combat/magic-casting code (entirely outside
-`MotionInterpreter`/`MotionTableManager`, not read for this audit) layers
-its own ADDITIONAL "can't move while casting" rule on top of this queue
-mechanism — that would live in the combat/magic subsystem and needs a
-separate targeted read, not a live capture.
-
-**Additional residual surfaced by the flow-tracing pass, item 1 (stance
-change):** the mechanism (`GetObjectSequence` Branch 1 + `GetLink`) is
-confirmed parity, but whether acdream's higher-level default-combat-mode
-selection (`CombatInputPlanner.GetDefaultCombatModeDecision`, not read in
-this audit) picks the exact same weapon-style-to-CombatMode mapping as
-retail's `ClientCombatSystem::GetDefaultCombatMode` (`0x0056B310`) in every
-edge case was NOT traced — flagged as a small untraced item, not a
-confirmed divergence.
-
-**Ranked feel-impact of these 7, most to least:** all 7 came back parity —
-an unusual, striking result for a from-scratch port of this scope. Ranking
-by residual RISK rather than impact (i.e., where a future capture is most
-likely to still surface a surprise, since several parity claims rest partly
-on DAT-content assumptions rather than pure code): (1) item 7's untraced
-combat/casting-layer interrupt rule and item 1's untraced default-combat-mode
-mapping are the two loose threads worth a follow-up read (not a live
-capture); (2) items 3/4/6 (turn cycles, walk-run link, general link
-traversal) are the most solid — confirmed via both the acdream code AND an
-independent cross-check against ACE's own C# `MotionTable.cs` port, which
-shows the same double-hop structure; (3) items 2/5 (landing, backward/strafe)
-are effectively closed — in both cases the "gap" the flow's framing
-hypothesized doesn't exist in retail itself (one universal landing
-transition; forward/right cycles reverse-played rather than distinct
-backward/left clips), corroborated for item 5 by holtburger's wire-level
-`MovementCommand` enum showing `WalkBackwards`/`TurnLeft`/`SidestepLeft` as
-distinct wire ids (confirming the reversal is a client animation-layer
-transform, not a wire-format absence). Net: of the 7 flows the task asked to
-trace, all are parity; the two follow-up threads (combat-layer cast
-interrupt, default-combat-mode mapping) are outside the `MotionInterpreter`/
-`CMotionTable`/`CSequence` file set this audit focused on and are noted for
-a future combat/magic-scoped audit, not scheduled as animation fixes.
-
-## 3. TS-50 / TS-51 current scoping (verified against current code, 2026-07-30)
-
-Both rows are precisely as described in the register — re-reading the actual
-code confirms rather than narrows either row. No promotion to a fix is
-recommended; both remain the correct classification (deliberate ordering
-adaptation with a bounded, named residual), not silent regressions.
-
-**TS-50 — which hook types still deliver late.** Read
-`src/AcDream.App/Rendering/Vfx/AnimationHookFrameQueue.cs:37-86` (`Capture`):
-for every hook produced by a sequence advance, the queue tests
-`hooks[i] is AnimationDoneHook` (line 75) and, ONLY for that one hook type,
-synchronously calls `sequencer.Manager.AnimationDone(success: true)` at
-capture time — i.e. inside the same call that advanced the sequence, matching
-retail `CPhysicsObj::process_hooks @ 0x00511550` timing exactly (semantic
-motion completion, Target/Movement/PartArray/Position manager tail all see it
-in the same quantum). EVERY OTHER hook type reaching this queue (from the
-`DatReaderWriter.Types.AnimationHook` hierarchy routed through
-`AnimationHookRouter` to `AudioHookSink`, `ParticleHookSink`,
-`TranslucencyHookSink`, `LightingHookSink` — i.e. sound playback, particle
-creation including `RetailCreateBlockingParticleHook`, translucency-fade
-starts, light attach, and `PhysicsScriptHook`/CallPES-adjacent triggers) is
-unconditionally appended to `_entries` (line 82-85) and only fires later, in
-`Drain()` (lines 88-125), which is called exactly once per render/update
-frame from `LiveEffectFrameController.Tick` at
-`src/AcDream.App/Update/LiveObjectFrameController.cs:107-126` — AFTER every
-live entity's root/part/equipped-child pose has been published for that
-frame (the comment at `LiveObjectFrameController.cs:109-113` names this
-explicitly: "acdream currently keeps non-AnimationDone hooks at this
-deferred shared boundary under TS-50"). So the answer to "which hook types
-still deliver late": **all of them except semantic AnimationDone** — sound,
-particle, light, translucency, and CallPES/script-chain hooks can be up to
-one render frame later than retail's per-object `process_hooks` moment.
-Feel-visible risk is concentrated in **CallPES** (a hook that triggers a
-PhysicsScript chain, e.g. spawning a follow-up effect keyed to a specific
-animation frame) and blocking-particle creation tied to an attack's exact
-swing frame — a one-frame-late particle spawn on a fast weapon swing is the
-kind of thing a careful side-by-side viewer could notice, though nobody has
-filed a symptom against it yet. Audio/light/translucency lateness is far
-less likely to be perceptible at typical frame rates.
-
-**TS-51 — per-render-frame vs per-quantum tails.** Confirmed at
-`LiveObjectFrameController.cs:107-126`: `LiveEffectFrameController.Tick(float
-deltaSeconds)` advances `_particles.Tick(deltaSeconds)` and
-`_scripts.Tick(_scriptTime.CurrentScriptTime)` exactly once per call, and
-this controller is driven once per render/update frame (not once per
-admitted 30 Hz physics quantum per live object). Retail's
-`CPhysicsObj::UpdateObjectInternal @ 0x005156B0` advances each ordinary
-object's own ParticleManager then ScriptManager inside EVERY admitted
-quantum for THAT object, and `animate_static_object @ 0x00513DF0` uses a
-different order (Script → Particle → hooks) for the static-object workset.
-acdream's shared tail is Particle → Script after static hook capture,
-uniformly, once per render frame regardless of how many physics quanta a
-given object admitted that frame. Practical effect: on a catch-up frame
-(object advances several quanta at once, e.g. after a stall), the object's
-root/pose advances through all of them but its particle/script tail only
-advances once — an emitter that should have spawned N times in that
-interval spawns once with N ticks' worth of `deltaSeconds`, and static
-default-script/particle ordering runs in the opposite sequence from
-`animate_static_object`. This is a real feel-visible risk specifically for
-dense fast-tick emitters (rapid-fire spell effects, chain particle bursts)
-but is architecturally deep to fix (needs incarnation-bound per-object
-particle/script manager instances, which the register row itself names as
-the retirement condition) — not a quick promotion candidate.
-
-**Verdict:** neither row's scope has changed since the register was last
-written; both remain accurately described. Of the two, TS-50's CallPES
-lateness is the more plausible candidate for a future promotion (narrower
-blast radius — "make CallPES and blocking-particle hooks fire at capture
-time like AnimationDone, keep the rest deferred" is a bounded change),
-whereas TS-51 needs the larger incarnation-bound-manager refactor the row
-already flags.
-
-## 4. Issue #64 (local pickup animation) reassessment
-
-**Original hypothesis (filed 2026-05-14, pre-R3/R4/R6):** `OnLiveMotionUpdated`
-filters local-player self-echoes wholesale, so ACE's server-authored
-`Motion(MotionCommand.Pickup)` broadcast (via
-`Player_Inventory.AddPickupChainToMoveToChain` →
-`EnqueueBroadcastMotion(motion)`) never reaches the local player's animation
-path. That exact function (`OnLiveMotionUpdated`) no longer exists in the
-current tree (`git grep` for it returns nothing) — the inbound motion path
-has been rewritten at least twice since (R4-V5's local/remote unification,
-then the J-slice Runtime extraction), so the original hypothesis needs to be
-re-evaluated against the CURRENT architecture, not assumed stale or assumed
-still-broken.
-
-**Current architecture, traced end to end:**
-
-1. `src/AcDream.App/Physics/LiveEntityNetworkUpdateController.cs:216-241`
-   (`OnMotion`) — the first gate is a TIMESTAMP staleness check
-   (`_authorityGate.TryAcceptMotion`), unrelated to self-echo.
-2. Lines 224 and 243-259 — the REAL self-echo gate, `R4-V5 (pin P1)`: `bool
-   retainPayload = update.Guid != _playerServerGuid || !update.IsAutonomous;`
-   This drops an entire UpdateMotion packet ONLY when it targets the local
-   player's guid AND the packet's wire-level `IsAutonomous` byte is set — the
-   comment cites retail `CPhysics::SetObjectMovement`'s autonomous gate
-   (`0x00509690 @0050972e`, raw 271370-271431) and explains WHY: ACE reflects
-   the client's own outbound `MoveToState` back to the sender with
-   `IsAutonomous=1` hardcoded (`MovementData.cs:162`,
-   `Player_Networking.cs:365` in the ACE reference), so this gate exists
-   specifically to drop THAT reflection, not every inbound packet addressed
-   to the player.
-3. If the packet survives, the local-player branch at lines 450-509 routes
-   through the SAME `RemoteInboundMotionDispatcher.Apply` used for remotes
-   (`src/AcDream.App/Physics/RemoteInboundMotionDispatcher.cs`), which for a
-   `MovementType == 0` packet calls `motion.MoveToInterpretedState(interpreted,
-   animationSink)` (`RemoteInboundMotionDispatcher.cs:108-112`).
-4. `MotionInterpreter.MoveToInterpretedState`
-   (`src/AcDream.Core/Physics/MotionInterpreter.cs:2697-2743`) replays each
-   entry in `ims.Actions` (the Commands[] one-shot list, populated by
-   `InboundInterpretedMotionFactory.Create` from the wire's `Commands`
-   field — `src/AcDream.App/Physics/InboundInterpretedMotionFactory.cs:46-63`)
-   through `DispatchInterpretedMotion`, with exactly ONE local-player-specific
-   filter at line 2735: `if (IsLocalPlayer && a.Autonomous) continue;` — this
-   is scoped to the PER-ACTION autonomous bit inside the Commands[] entry
-   (`MotionItem.PackedSequence & 0x8000`), not a blanket "is this the local
-   player" drop.
-
-**Current best hypothesis:** ACE's Pickup broadcast is server-initiated (built
-via `EnqueueBroadcastMotion`, not a reflected client `MoveToState`), so both
-gates that could drop it — the packet-level `IsAutonomous` check (step 2) and
-the per-action `Autonomous` bit check (step 4) — should read `false` for it,
-same as for any other server-authored one-shot action a remote observer would
-see. If that reading of ACE's flag values is correct, **the R4-V5 local/remote
-unification (which post-dates #64's filing by roughly two months) likely
-fixed this issue as an architectural side effect**, without anyone
-specifically targeting #64. This is a hypothesis, not a confirmed fix — this
-audit is report-only and did not launch the client or trigger a live pickup.
-
-**Recommended next step (not performed here):** re-test #64 live with
-`ACDREAM_DUMP_MOTION=1` set, trigger a close-range pickup as `+Acdream`, and
-check the log for a `UM guid=<player> ... cmd=...` line whose resolved
-command carries the Pickup action bit, followed by the sequencer actually
-playing the one-shot cycle. If it still fails, the next diagnostic is to
-confirm whether ACE's Pickup broadcast really sets `Autonomous=false` at
-both the packet and per-action level (a WireMCP capture on the loopback
-`UpdateMotion (0xF74D)` packet during a pickup would settle this instead of
-reading ACE source), since a wrong assumption there is the one way this
-hypothesis could be wrong.
-
-## 5. Emote/action surface (AD-57) gap sizing
-
-**What retail would play:** an animated social emote (retail's action-class
-MotionCommand — the `0x10000000` bit family, e.g. a wave/point/bow/salute
-cycle, as opposed to `/e <text>` roleplay chat text) is queued through the
-SAME `CMotionInterp` action-list machinery already ported: `AddAction` onto
-`RawMotionState`/`InterpretedMotionState`, packed onto the wire by
-`RawMotionState::Pack` (retail `0x0051ed10`) as `num_actions` +
-per-action pairs, broadcast to observers as a Commands[] entry on
-`UpdateMotion`, and resolved into a `CMotionTable` action-class cycle via the
-same `CMotionTable::GetObjectSequence` path used for locomotion cycles.
-
-**What acdream has, precisely:** per section 4's trace, the RECEIVING half of
-this pipeline is fully wired and (per the current-best-hypothesis above)
-likely already plays a server-broadcast one-shot action correctly for both
-local and remote observers — `InboundInterpretedMotionFactory` parses
-Commands[] into `InboundMotionAction`s, `MotionInterpreter.MoveToInterpretedState`
-replays them through `DispatchInterpretedMotion` into the same
-`CMotionTable`/`CSequence` cycle-selection path as any other motion. The
-SENDING half — the local player's own input constructing and enqueueing an
-autonomous action, e.g. from a `/wave`-style command — has no production call
-site: `grep -r "\.AddAction(" src/AcDream.App` returns nothing outside test
-code (`RawMotionState.AddAction`/`InterpretedMotionState.AddAction` are
-exercised only by unit tests, confirmed during this audit). The chat command
-catalog (`src/AcDream.UI.Abstractions/Panels/Chat/RetailClientCommandCatalog.cs:144-150,232-234`)
-has `/emote` and `/emotes`, but these are documented as the roleplay TEXT
-emote (`/e <text>` — chat-log output), not an animated action — there is no
-slash command or UI affordance in the catalog for a genuine visual emote.
-
-**Gap size:** this is a clean, well-isolated feature gap, not a divergence
-of any shipped behavior — the register row (AD-57, re-argued 2026-07-30) is
-correct that "every currently-shipped movement packet matches retail byte-shape;
-the gap only manifests when emote-class autonomous actions are implemented."
-The work to close it is bounded and almost entirely additive: (a) a
-retail-sourced list of which MotionCommand action IDs are genuine social
-emotes and what UI/command surface retail exposes them through (character
-menu right-click? a `/motion` or numbered emote command? — this needs a
-named-retail grep, not guessed), (b) a client input path that calls
-`MotionInterpreter.DoMotion`/`AddAction` with the right action ID and
-`Autonomous=true`, and (c) confirming the existing outbound packer already
-emits it correctly (it should, since `RawMotionStatePacker` already handles
-the `Actions` list per AD-57's own text). No architecture changes are
-required — this is squarely a "wire up an existing, tested machine" gap, sized
-small-to-medium (one research pass to find the retail command surface, one
-implementation pass to wire input → `AddAction`).
-
-## 6. Ranked gap catalog + recommended fix order
-
-**Headline result:** this audit set out to find where acdream's animation
-system diverges from retail and found the system in unusually good shape.
-Two independent research passes (a symbol-by-symbol method-coverage sweep
-and a 7-flow feel-visible trace) plus the lead auditor's own full read of
-the four core files converged on the same conclusion: `MotionInterpreter`
-(`CMotionInterp`), `CSequence`, `CMotionTable`, and `MotionTableManager` are
-faithful, extensively retail-cited ports, and all 7 traced feel-visible
-flows came back parity — three of them (landing severity, backward/strafe
-cycles, in-place-turn-cycle-vs-omega) because the richer retail behavior the
-flow's framing assumed doesn't actually exist in retail either. The gap
-catalog below is therefore short and each entry is genuinely small.
-
-**Ranked by feel-impact, most to least:**
-
-1. **AD-57 — animated emote authoring gap (feel-visible, bounded scope).**
-   The RECEIVING half of retail's action-class one-shot animation system
-   (server-broadcast one-shots like Pickup, and presumably other players'
-   emotes) is fully wired and plays correctly through the same
-   `GetObjectSequence` Branch 3 machinery as any other motion (see section
-   4/5). The SENDING half — the local player triggering their OWN animated
-   emote (retail's `/wave`-equivalent) — has no production call site;
-   `RawMotionState.AddAction`/`InterpretedMotionState.AddAction` are
-   exercised only by unit tests. This is the most user-visible gap in the
-   catalog (a whole category of retail behavior — animated social
-   gestures — is simply absent from the client), but it is squarely a
-   "wire up an existing, tested machine" gap: no architecture change, no
-   new port, just (a) a named-retail grep for which MotionCommand action
-   IDs are genuine emotes and what UI surface retail exposes them through,
-   (b) an input path that calls `DoMotion`/`AddAction` with the right
-   action ID and `Autonomous=true`, (c) confirming the existing
-   `RawMotionStatePacker` emits it correctly (should already, per AD-57).
-
-2. **TS-50 residual — CallPES and blocking-particle hooks up to one render
-   frame late (already known, narrow promotion candidate).** Verified
-   against current code (section 3): only the semantic `AnimationDoneHook`
-   fires at capture time; every other hook type (CallPES/script-chain
-   triggers, particle creation including blocking particles, sound, light,
-   translucency-fade starts) is deferred to `AnimationHookFrameQueue.Drain()`,
-   called once per render frame after all entities' poses publish. Most
-   feel-visible on a fast weapon swing where a blocking-particle effect is
-   keyed to an exact frame. Bounded fix: make CallPES and blocking-particle
-   hooks fire at capture time like `AnimationDoneHook`, keep the rest
-   deferred — narrower than the full TS-51 refactor below.
-
-3. **Issue #64 — local pickup animation not rendering (likely already
-   fixed, zero-cost to verify).** Section 4's trace shows the R4-V5 local/
-   remote unification (which post-dates #64's filing) architecturally
-   closed the exact mechanism the original hypothesis blamed: the
-   packet-level and per-action autonomous-echo gates are now scoped
-   precisely enough that a server-authored one-shot (non-autonomous, by
-   construction) should reach the local player's `DispatchInterpretedMotion`
-   exactly like it does for remotes. This needs a 2-minute live re-test
-   (`ACDREAM_DUMP_MOTION=1`, trigger a close-range pickup), not an
-   engineering investment — likely already closed as a side effect of
-   unrelated work and just needs its ISSUES.md status updated.
-
-4. **`CMotionInterp::get_adjusted_max_speed` unported (narrow, needs a
-   cdb read before it's even confirmed live).** The one genuine
-   unexplained gap from the method-coverage sweep (section 1): retail's
-   dead-reckoning catch-up path chooses between `get_max_speed` and this
-   sibling via a static toggle (`InterpolationManager::fUseAdjustedSpeed_`)
-   whose default this audit could not resolve from static analysis alone.
-   acdream always uses `GetMaxSpeed()` for remote catch-up. If the toggle
-   defaults to the adjusted variant in retail, acdream's remote
-   dead-reckoning catch-up speed could be systematically using the wrong of
-   two very similar formulas — narrow blast radius (one clamp value in one
-   catch-up path), plausible feel effect (slightly different snap-back
-   speed on remotes catching up after a network stall). Per the project's
-   own retail-debugger toolchain, this is a cdb-read-the-static-value
-   question, not a guess-and-ship one.
-
-5. **TS-51 residual — particle/script tails once per render frame instead
-   of once per admitted physics quantum (already known, larger refactor).**
-   Verified against current code (section 3): on a catch-up frame where an
-   object advances several 30 Hz quanta at once, its particle/script tail
-   only advances once with the accumulated `deltaSeconds`, and static
-   default-script/particle ordering runs Particle→Script instead of
-   retail's Script→Particle→hooks. Most feel-visible for dense fast-tick
-   emitters (rapid spell-effect chains). The register row itself names the
-   retirement condition (incarnation-bound per-object particle/script
-   manager instances) — this is real architectural work, not a quick
-   promotion, and should stay queued behind the current M4 feature-work
-   order rather than jumping the line for this audit.
-
-6. **Two untraced items outside this audit's file scope (flagged, not
-   confirmed divergences).** The flow-tracing pass surfaced two loose
-   threads it didn't have scope to chase: (a) whether combat/magic-casting
-   code (entirely outside `MotionInterpreter`/`MotionTableManager`) layers
-   its own additional "can't move while casting" rule on top of the
-   confirmed-parity action-queue mechanism; (b) whether
-   `CombatInputPlanner.GetDefaultCombatModeDecision` picks the same
-   weapon-style-to-CombatMode mapping as retail's
-   `ClientCombatSystem::GetDefaultCombatMode` (`0x0056B310`) in every edge
-   case. Both are plausible-but-unconfirmed and belong to a combat/magic-
-   scoped audit, not this animation-scoped one — recommended as a future
-   audit topic, not a fix.
-
-**Recommended fix order** (cheapest/highest-confidence first): (1) re-test
-#64 live and close the issue if confirmed — essentially free; (2) research
-+ wire the emote-sending path (AD-57) — bounded, additive, no architecture
-change, the single most user-visible improvement available; (3) narrow
-TS-50's promotion to cover CallPES + blocking-particle hooks specifically;
-(4) cdb-verify `fUseAdjustedSpeed_`'s retail default before deciding whether
-`get_adjusted_max_speed` needs porting at all; (5) queue the full TS-51
-incarnation-bound-manager refactor behind current M4 feature work, since it
-is real architectural investment rather than a bounded fix; (6) file a
-follow-up combat/magic-scoped audit for the two untraced items rather than
-guessing at their status here.
-
-This audit made no code changes and files no fixes directly — items 1-4
-above are small enough that the user may want to fold them into the next
-convenient M4 work session; item 5 should go through the normal roadmap
-process (a new phase/slice, not a drive-by fix) given its architectural
-size; item 6 needs its own investigation before any fix is proposed.

-# #167 ConstraintManager leash — constants recovered + arming flow (Campaign P P5)
-
-**2026-07-30.** Both #167 blockers are now research-solved; only the port
-remains. No cdb session was needed: the two "unknown x87 constants" were
-recovered by decoding the raw machine code of the matching binary
-(`C:\Users\erikn\Downloads\acclient.exe`, v11.4186, PDB-paired — verified
-GUID match per the retail debugger toolchain doc).
-
-## 1. The getters, byte-decoded (FACT)
-
-`CPhysicsObj::GetStartConstraintDistance @ 0x0050ebc0` and
-`GetMaxConstraintDistance @ 0x0050ec10` are FPU-return getters whose
-`fld` operands Binary Ninja elided (the pseudo-C shows a bare
-`this->m_position;`). Raw bytes (file offset 0x10ebc0/0x10ec10):
-
-```
-3b 0d 58 3d 84 00   cmp  ecx, [0x00843d58]      ; this == player_object?
-75 1d               jnz  non_player
-8b 41 4c            mov  eax, [ecx+0x4c]        ; m_position.objcell_id
-25 ff ff 00 00      and  eax, 0xFFFF
-3d 00 01 00 00      cmp  eax, 0x100
-73 07               jae  indoor                 ; low16 >= 0x100 = EnvCell
-d9 05 <rdata>       fld  dword [outdoor_const]
-c3                  ret
-indoor: d9 05 <..>  fld  dword [indoor_const]
-c3                  ret
-non_player:         ; identical cell test, second constant pair
-```
-
-Constant values read from `.rdata`:
-
-| | player outdoor | player indoor | remote outdoor | remote indoor |
-|---|---|---|---|---|
-| Start (0x007c6abc..c8) | **10.0** | **5.0** | 10.0 | 5.0 |
-| Max (0x007c6acc..d8) | **50.0** | **20.0** | 50.0 | 20.0 |
-
-Two consequences (FACT):
-
-1. **The player-vs-remote branch is vestigial** — both sides load
-   identical values. Effective semantics: `start = outdoor 10 m /
-   indoor 5 m`, `max = outdoor 50 m / indoor 20 m` (indoor = cell low16
-   ≥ 0x100).
-2. **ACE's `GetStartConstraintDistance` is INVERTED**
-   (`ACE PhysicsObj.cs:620`: outdoor 5 / indoor 10). ACE's max mapping
-   (outdoor 50 / indoor 20) matches the binary. Do NOT copy ACE's start
-   mapping. (feedback_acme_oracle / binary-wins rule.)
-
-## 2. The arming flow — `SmartBox::HandleReceivedPosition @ 0x00453fd0` (FACT)
-
-Pseudo-C lines ~92940-93060. After the update-time staleness gates and
-`unset_parent`/`SetPlacementFrame` handling:
-
- **Remote object** (`arg2 != this->player`): call
-  `MoveOrTeleport(obj, &recvPos, ts, arg5, arg6)`; **only if it returns
-  nonzero** (the position was NOT hard-teleport-applied), arm the leash
-  **anchored to the object's own current position**:
-  `ConstrainTo(obj, &obj->m_position, start, max)` (0x00454254-72).
- **Player, teleport-newer** (`newer_event(TELEPORT_TS, ts)`):
-  `SmartBox::TeleportPlayer(&recvPos)`, then
-  `ConstrainTo(player, &recvPos, start, max)` — anchored to the
-  **received** position — then `set_velocity(player, {0,0,0}, 1)`
-  (0x0045415f-c0).
- **Player, normal**: `ConstrainTo(player, &recvPos, start, max)`
-  anchored to the received position; then, if
-  `cmdinterp->UsePositionFromServer() && arg5`,
-  `InterpolateTo(&recvPos, -GetAutonomyLevel())` (0x004541c9-422c).
-
-The taper/enforcement side (`ConstraintManager::UseTime` feeding
-`adjust_offset`, `IsFullyConstrained = ConstraintDistanceMax * 0.9 <
-offset`) is already ported in
-`src/AcDream.Core/Physics/Motion/ConstraintManager.cs` (R5-V1,
-`docs/research/2026-07-03-r5-managers/`); it has simply never been armed.
-
-## 3. Port shape for P5 (INFERENCE — implementation guidance)
-
-1. Add the four-constant getters (outdoor/indoor by full cell id low16)
-   at the body/host layer; keep the vestigial player/remote split OUT
-   (note it in a code comment with this doc as the cite).
-2. Arm at acdream's inbound-position equivalents of the three branches:
-   the remote UpdatePosition acceptance tail (post-`MoveOrTeleport`
-   routing in the live-entity network update path) and the local
-   player's accepted-Position path (normal + teleport). Anchor per §2.
-3. `PhysicsBody.IsFullyConstrained` (register TS-35 stub) becomes a read
-   through `PositionManager`/`ConstraintManager`, so
-   `jump_is_allowed`'s ported gate fires (WeenieError 0x47) while
-   rubber-banding. TS-35 and #167 retire together, same commit.
-4. Conformance tests: constant table incl. the ACE-inversion pin
-   (outdoor start MUST be 10, not 5); leash-armed jump refusal;
-   remote-vs-player anchor difference; teleport-branch velocity zero.
-
-## Open questions
-
-None for the constants/flow. Remaining implementation risk is only
-where acdream's position-acceptance seams sit today (J6.3 moved
-teleport correlation into Runtime — the implementer must find the
-current owner rather than trusting older file cites).
-
-## As-ported (Campaign P Slice P5, 2026-07-30)
-
-The implementation risk flagged above resolved to these CURRENT seam owners
-(post-J-slices) — recorded here so the next reader doesn't have to re-derive
-them:
-
- **Constants** — `src/AcDream.Core/Physics/Motion/ConstraintDistance.cs`.
-  Keyed purely on the object's own full cell id's low 16 bits (`>= 0x0100` =
-  indoor); the vestigial player/remote branch from §1 is deliberately not
-  represented as an API parameter.
- **Remote arm** — `src/AcDream.App/Physics/LiveEntityNetworkUpdateController.cs`,
-  the inbound `UpdatePosition` handler's remote branch (`update.Guid !=
-  _playerServerGuid`), immediately after the `remotePlacementRequired`
-  hard-teleport block returns (that block already covers retail's
-  `MoveOrTeleport` Branch A / hard-place case; everything reached past it is
-  "did not hard-place"). One call site covers BOTH player-remote and NPC
-  remotes — retail's `SmartBox::HandleReceivedPosition` doesn't distinguish
-  them either, only `GetStart/MaxConstraintDistance`'s now-omitted vestigial
-  branch did. Anchored to the live `IPhysicsObjHost.Position` (which reads
-  `RemoteMotion.Body.Position` + the tracked cell id), matching retail's
-  "anchored to the object's own current position" — since the anchor and
-  `_host.Position` read are the same value at call time,
-  `ConstraintManager.ConstrainTo`'s initial offset is always 0 regardless of
-  whether the routing above just far-snapped or left a near-correction
-  queued.
- **Remote per-tick taper + `IsFullyConstrained` push** — already wired
-  pre-P5 for the taper (`RuntimeRemotePhysicsUpdater.Tick`/`TickHidden` call
-  `PositionManager.AdjustOffset` every tick via the pre-existing R5-V3
-  sticky/constraint chain); P5 added the `PhysicsBody.IsFullyConstrained =
-  host.PositionManager.IsFullyConstrained()` push at the same two call
-  sites, since `MotionInterpreter` only holds a `PhysicsBody` (no host
-  reference) and needs a live value to read.
- **Local player arm** — `src/AcDream.Runtime/Gameplay/PlayerMovementController.cs`:
-  `SetPositionCore` (teleport: `UnConstrain` then re-`ConstrainTo` after the
-  existing `StopCompletelyAtPhysicsObjectBoundary` velocity zero — composed,
-  not duplicated) and `CommitPreparedPosition` (mirrors the same pair for
-  the deferred player-mode-entry commit path); `BlipPosition` (ForcePosition:
-  `ConstrainTo` only, no teardown — matches `SmartBox::BlipPlayer` surviving
-  motion/velocity/stick). Anchored to `_body.CellPosition` (the just-applied
-  received position).
- **Local player per-tick taper + push** — `PlayerMovementController.Update`
-  already called `PositionManager.AdjustOffset` every physics tick pre-P5;
-  P5 added the `_body.IsFullyConstrained = PositionManager?.IsFullyConstrained()
-  ?? false` push immediately after, at the same chokepoint.
- **TS-35 retirement** — `PhysicsBody.IsFullyConstrained` stayed a plain
-  settable bool (not a computed property) so the ~40 pre-existing direct-set
-  unit tests keep working; the per-tick pumps above are its single writers
-  now, matching the project's per-entity single-owner-write pattern.

-# The landing bounce family — retail bounce vs ground vs slide (investigation, report-only)
-
-**Date:** 2026-07-30 · **Status:** IMPLEMENTED (same day — see §Implementation)
-**Symptoms (user, live gate):** (1) downhill jumps glide instead of bouncing;
-(2) flat-ground jumps at speed/height don't bounce; (3) uphill jumps get stuck
-in weird animations, flapping and gliding. Speed (#266) and roof slide
-(#265's freeze) are fixed and unaffected.
-
-## The retail mechanism (decomp, read end-to-end this session)
-
-Three functions compose the whole behavior:
-
-### 1. The floor-touch dual record (plane handler, 0x0050d100-0x0050d30c)
-
-Touching a floor plane records **two independent facts**:
-
-```c
-if (step_down || !(state & CONTACT) || is_valid_walkable(plane))
-    set_contact_plane(plane)                 // grounding fact
-if (!(state & CONTACT) && !step_down) {
-    set_collision_normal(plane.N);           // collision fact
-    collided_with_environment = 1;
-}
-```
-
-A landing (not already in contact, not a step-down probe) is BOTH a contact
-AND an environment collision carrying the floor normal. Ordinary walking
-(already in contact / step-down glue probes) records only the contact —
-that is why walking never bounces.
-**acdream's transition already ports this faithfully**
-(`TransitionTypes.cs:3410-3415` — `!oi.Contact && !sp.StepDown` →
-`SetCollisionNormal` + `CollidedWithEnvironment = true`).
-
-### 2. SetPositionInternal (0x00515330, read fully — VELOCITY-SIGN-FREE)
-
-```
-contact     = collision_info.contact_plane_valid          (no velocity test)
-on_walkable = contact && contact_plane.N.z >= floor_z     (set_on_walkable → HitGround/LeaveGround)
-handle_all_collisions(collision_info, prevContact, prevOnWalkable)   ← velocity UNMODIFIED
-```
-
-There is **no `Velocity.Z <= 0` landing gate and no velocity zeroing**
-anywhere in retail's commit. Contact is a per-frame fact from the
-transition's contact plane; the bounce is the velocity reflect; they are
-independent and coexist — you can be "landed" this frame AND carry
-reflected +Z that lifts you off next frame. That IS the bounce chain.
-(Our Core `PhysicsObjUpdate.CommitSetPositionTransition` is already a
-faithful port of this function — used by teleport/remote placement, NOT by
-the local player's per-tick path.)
-
-### 3. handle_all_collisions (0x00514780) + elasticity
-
-For fsf≤1, should-reflect (NOT(was-walkable AND still-walkable) or the
-garbled state-flag override), valid collision normal, and `v·n < 0`:
-
-```
-v += -(v·n) · (elasticity + 1) · n        // pc:282712
-```
-
-`DEFAULT_ELASTICITY = 0.05` (byte constant @0x007c6a7c; ctor writes at
-0x005124d3/0x0051d537; `set_elasticity` clamps to [0, 0.1]). So every
-landing reverses 5% of the impact's normal component and keeps the full
-tangential component:
-
- **Flat ground at speed/height:** v=(6,0,−7) → v'=(6,0,+0.35) — forward
-  carry plus a visible pop at speed. Symptom (2).
- **Downhill:** reflect is off the SLOPE normal — each contact pops the body
-  off-slope while tangential speed persists → contact/airborne chain =
-  the characteristic downhill bounce. Symptom (1).
- **Uphill:** the reflect kills the into-slope component at impact, contact
-  stands, HitGround fires once, land animation plays. Symptom (3)'s clean
-  retail counterpart.
-
-## Why acdream glides/flaps instead (the adaptation stack)
-
-`PlayerMovementController.cs:2032-2079` (the per-tick commit) replaces
-retail's SetPositionInternal with a hand-rolled block:
-
-1. **AD-25 landing gate:** `if (resolveResult.IsOnGround && Velocity.Z <= 0)`
-   — needed because *our resolver reports IsOnGround even during an UPWARD
-   jump (it always step-downs)*. Retail has no such gate: an ascending mover
-   simply finds no contact plane (it moves away from it; the touch test
-   fails), so contact clears naturally.
-2. **The bounce killer:** `if (Velocity.Z < 0) Velocity.Z = 0` on landing,
-   whose comment says its purpose plainly: *"makes handle_all_collisions'
-   landing reflect a no-op — dot(v,n)=0."* This retired the old
-   "micro-bounce death spiral" — but that spiral was caused by our OWN
-   gate (reflected +Z defeating the `Velocity.Z<=0` landing test), not by
-   the reflect being wrong. The workaround deleted retail's legitimate
-   bounce.
-3. With the reflect suppressed, the new #265 residual-velocity fix correctly
-   preserves landing momentum — which now SLIDES via calc_friction instead
-   of bouncing. Hence "I glide but that's incorrect."
-4. **Uphill flap:** during the up-leg our resolver glues to the slope
-   (IsOnGround true) while the gate refuses to ground (v.z > 0) →
-   Contact/OnWalkable and HitGround/LeaveGround edges cycle against the
-   animation state machine → "weird animations, flapping and gliding."
-
-## Hypotheses (ranked)
-
-1. **H1 (root, high confidence — every link read this session):** the
-   AD-25 landing gate + Velocity.Z hand-zero must be REPLACED by retail's
-   SetPositionInternal semantics, which requires first fixing the underlying
-   resolver divergence: **the transition must not produce a contact plane
-   for a mover ascending away from the ground** (retail's step-down/touch
-   conditions do this naturally; ours "always step-downs"). With that fixed,
-   route the per-tick commit through the already-ported
-   `CommitSetPositionTransition` and delete the hand-rolled block — reflect,
-   contact, HitGround/LeaveGround, and land animation then compose exactly
-   as retail.
-   - Falsify by: cdb trace on retail (bp SetPositionInternal +
-     handle_all_collisions, dump v before/after while jumping downhill) —
-     expect unmodified impact v entering, 5% normal reversal exiting.
-2. **H2 (contributing detail):** the garbled `state & <mush>` override in
-   handle_all_collisions' gate (our port maps it to Sledding) and the
-   `0x20000` Inelastic mapping need byte-decode confirmation before the
-   rework — a wrong flag here changes when reflects fire while grounded.
-3. **H3 (animation-side residual):** if flap persists after H1, the
-   MotionInterp land/fall transition (LandJump vs falling-hold) has its own
-   gate to audit — deferred until H1 is in.
-
-## What we've ruled out
-
- The transition's landing dual-record being missing — ours is faithful
-  (TransitionTypes.cs:3410).
- HandleAllCollisions' reflect math/elasticity — ported correctly
-  (PhysicsObjUpdate.cs:198, elasticity 0.05 default present).
- The #265 residual-velocity fix being wrong — it exposed the missing
-  bounce; it didn't cause it.
-
-## Recommended next step
-
-Approve H1 for implementation: (a) byte-decode the two garbled flags (H2)
-first; (b) find + port retail's exact ascent/step-down gating in the
-transition (the one remaining unread mechanism); (c) cut the per-tick commit
-over to `CommitSetPositionTransition`; (d) re-run the roof/downhill/flat/
-uphill matrix live. Optional pre-implementation confirmation: the H1 cdb
-trace against live retail.
-
-## What this is NOT
-
-Not a missing-elasticity port and not a missing collision-record — both
-exist and are faithful; the bounce is suppressed by our own landing-commit
-adaptation (AD-25 family), whose reason-for-being is the resolver's
-ascent-glue divergence.
-
-
-## Implementation (2026-07-30, user-approved)
-
-All three retail mechanisms are now live; the AD-25 adaptation stack is
-deleted:
-
-1. **check_contact seeding** (`PhysicsEngine.ResolveWithTransition`): a body
-   in transient CONTACT seeds the transition's contact state ONLY while
-   `v · contactPlane.N <= ε` (0.0002 = PhysicsGlobals.EPSILON, retail
-   0x0050f5b0); a failing body seeds the last-known plane alone (retail
-   get_object_info's init_last_known_contact_plane branch). The plane
-   requirement is strict — Contact-without-plane is unrepresentable in
-   retail. Body-less callers keep the legacy isOnGround seed (test rigs).
-2. **SetPositionInternal-shaped commit** (`PlayerMovementController`): the
-   `Velocity.Z <= 0` landing gate and the landing `Velocity.Z = 0` hand-zero
-   are DELETED. Contact commits purely from `resolveResult.InContact` /
-   `OnWalkable`, HitGround fires on the airborne→walkable edge, and
-   `HandleAllCollisions` runs with the UNMODIFIED impact velocity — the 5%
-   elasticity reflect is live. The whole commit is gated on
-   `resolveResult.Ok && candidateMoved` (retail runs SetPositionInternal
-   only when the transition succeeded AND the candidate moved — pc:283657;
-   AD-41's row updated accordingly). Zero-move frames leave contact state
-   untouched (this is what keeps a standing body stable: a zero-move
-   resolve cannot re-derive a plane because no sweep runs).
-3. **Byte decodes** (this doc's H2): the handle_all_collisions gate override
-   is `state & 0x800000` = Sledding; the zero branch is `state & 0x20000` =
-   Inelastic; the reflect fires strictly on `dot < 0` (`test ah, 5; jp`).
-   Our port had all three correct already — no change.
-
-Settle behavior: a real landing (|v| ≥ 0.25 m/s) bounces at 5% and the hop
-chain decays geometrically; sub-0.25 m/s impacts are consumed by retail's
-unconditional small-velocity zero (PhysicsBody.UpdatePhysicsInternal), so a
-standing body never micro-bounces. calc_acceleration turns gravity off for
-Contact+OnWalkable bodies, which is what makes rest bit-stable.
-
-Test re-baselines (each documented in place): the landing-survival pin now
-measures decay after the hop chain settles; `LiveCompare_Tick0/376` pin the
-new IsOnGround=false on their zero-move ticks (the captured `true` was the
-retired seed echo — tick 376's captured body even carries an 11.8 m/s
-grounded velocity from the deleted get_state_velocity-overwrite era);
-`RemoteDeOverlapMechanismTests.GroundedBody` now carries the plane a real
-grounded body always has (the big-creature 1.80 m expectation was calibrated
-against the unrepresentable flags-without-plane fixture; production settles
-at 1.58 m, unchanged before/after). New pins:
-`LandingBounceSeedingTests` (ascent no-seed, rest keeps-contact, strict
-plane, slope 5% reversal + tangential preservation, Sledding override).
-
-Verification: complete Release suite 10,031 passed / 5 skips / 0 failures.
-Live gate (downhill bounce chain, flat-ground pop, uphill clean landing,
-roof slide intact, walking intact) pends the user's next session.

-# Movement Parity Audit — Retail vs acdream (2026-07-30)
-
-**Status: COMPLETE — report-only investigation, no code changes made.**
-
-Scope: input → intent → wire → presentation for player + remote movement.
-Explicitly OUT of scope (closed by Campaign P, physics/collision proper):
-stat chain, friction, sphere lists, leash, PK flags. See
-`docs/plans/2026-07-29-physics-parity-campaign.md`'s closeout. This audit
-picks up the *movement wire/presentation* seam Campaign P did not touch.
-
-Legend: **FACT** = confirmed against named-retail decomp byte/pseudo-C
-(cited address + `acclient_2013_pseudo_c.txt` line) or cross-referenced
-against a second independent client (holtburger / Chorizite). **INFERENCE**
-= plausible reading where the decompiler dropped x87 detail (a known
-Binary Ninja artifact class, see `claude-memory/feedback_bn_decomp_field_names.md`)
-and could not be fully disambiguated in this pass.
-
---
-
-## 1. Outbound semantics table
-
-Retail's outbound tree (from `claude-memory/project_retail_motion_outbound.md`,
-re-verified this session):
-
-```
-WASD keypress → CommandInterpreter::SendMovementEvent (0x006B4680, per-frame)
-  → MoveToStatePack → SendMoveToStateEvent → 0xF61C
-at-rest heartbeat → CommandInterpreter::ShouldSendPositionEvent (0x006B45E0)
-  → SendPositionEvent (0x006B4770) → AutonomousPositionPack → 0xF753
-```
-
-| Intent | Retail send decision | acdream send decision | Verdict |
-|---|---|---|---|
-| W (run) | `SendMovementEvent` fires on any command-list head edge; wire carries `WalkForward`, `HoldKey.Run`, raw `forward_speed` (pre-scale). ACE auto-upgrades to `RunForward` for observers. | `PlayerMovementController` line 2106-2225: `outForwardCmd=WalkForward`, `outForwardSpeed=1.0f` (raw), `IsRunning=input.Run`; `changed` fires on cmd/hold/speed edges. `RawMotionStatePacker` D1 default-diff omits unchanged fields. | **Parity** (D6.2b/D1 shipped, verified 2026-07-01) |
-| W+Shift (walk) | Same tree, `HoldKey.None`, `forward_speed=1.0` (not run-scaled — ACE/observer scaling is a display-time concern, not sender concern). | Same — `axisHoldKey = movement.IsRunning ? Run : None` in `LocalPlayerOutboundController.BuildRawMotionState` (:234-244). | **Parity** |
-| Backward (X) | `WalkBackward` tag, own independent forward-channel entry; `adjust_motion` applies a flat **-0.65×** speed multiplier for the walk-forward↔backward pair (`apply_run_to_command`/`adjust_motion` 0x00528010, `acclient_2013_pseudo_c.txt:305343-305400` — **FACT**, spot-read confirms the `0x45000006→WalkForward, speed*=-0.65` canonicalization). | `outForwardCmd=WalkBackward`, `outForwardSpeed=1.0f` (PlayerMovementController :2111-2115). The **-0.65× backward scale lives in `MotionInterpreter.cs:543-546`** ("Retail-exact value; do not round to 0.65f") and is applied on the *interpreted* (local-animation) side, not re-derived on the wire (wire stays raw 1.0, matching D6.2b's "ACE recomputes" model). | **Parity** — same separation-of-concerns retail uses (raw wire, scaled interpretation) |
-| Strafe (Z/C) | `SideStepRight`/`SideStepLeft`; `adjust_motion` applies a flat **×1.248** (`(3.12/1.25)*0.5`) animation-rate scale, THEN `apply_run_to_command`'s SideStepRight branch (if Run) multiplies by `runRate` and clamps magnitude to **3.0** (`0x00527be0:305102-305122` — **FACT** for the 3.0 constant and the runRate scale; **INFERENCE** on the exact snap-vs-clamp branch polarity, x87 flag test unresolved by BN). | `MotionInterpreter.cs:558-564` cites the retail `±3.0` clamp and the 1.248 sidestep scale explicitly; `_activeInputSidestepCommand`/`SidestepUsesRunHold` in `PlayerMovementController.cs:2129-2133` carry the channel through to the wire. | **Parity** (ported; the one open item is the same x87-ambiguous branch retail's own disassembly leaves fuzzy — not an acdream gap) |
-| Turn (A/D) keyboard | `adjust_motion` canonicalizes Left→Right (`speed *= -1`), then `apply_run_to_command`'s TurnRight branch multiplies by a flat **1.5×** when hold key is Run (`0x00527be0:305096-305100` — **FACT**, byte-confirmed this session). Turn is a channel fully independent of forward/sidestep. | `MotionInterpreter.cs:554` `RunTurnFactor = 1.5f`, applied inside the ported `apply_run_to_command` (:1355+). Turn channel (`_activeInputTurnCommand`/`_activeInputTurnSpeed`) is independent of forward/sidestep in `PlayerMovementController.cs:2139-2143`. | **Parity** |
-| Autorun (Q) | See §4 below — separate section, real divergence found. | | **Divergent** |
-| Mouse-look turn (MMB) | `CameraSet::ToggleMouseLook`/`Rotate` (0x00457490/0x00458310) drive ordinary `TurnLeft`/`TurnRight` `MovePlayer` calls, always `HoldKey.Run`; speed = 2×filtered horizontal delta, dead-zone 0.02, cap 1.5. `MoveToState` sent on start/stop and every 0.5 s while active. | `MouseTurnDeadZone=0.02f`, `MouseTurnSpeedScale=2.0f`, `MouseTurnMaximumSpeed=1.5f`, `MouseMovementEventInterval=0.5f` (`PlayerMovementController.cs:376-380`) — exact match. | **Parity** (previously verified 2026-07-15, re-confirmed this session) |
-| Mouse-move-to (click-to-move) | Not part of the CommandInterpreter WASD tree; routes through `MoveToManager`/`MoveToPosition` (§3). | Same split in acdream (`MoveToManager.cs`, separate from `PlayerMovementController`'s per-frame channel). | **Parity** (architectural match) |
-| Stop (S key / all keys released) | `CommandInterpreter::UseTime` gates `ShouldSendPositionEvent` first, then falls through; a full command-list-empty state issues `MovePlayer(Ready, ...)` idle re-sync via `ApplyCurrentMovement`. | `PlayerMovementController` idle path falls to `_motion.RawState.ForwardCommand` staying at `Ready` default (0x41000003), consistent with retail's ctor default. | **Parity** |
-
-### TS-33 residual (exact current-code read)
-
-Register row (`docs/architecture/retail-divergence-register.md:264`, re-read
-this session): **"NARROWED 2026-07-15 — full AP tracker semantics are
-ported... Residual: acdream's single update path snapshots the AP predicate,
-emits a same-update MTS first when input changed, then AP. Retail proves
-`UseTime` performs Should→AP, but MTS originates in separate input
-callbacks; their relative same-tick callback/wire order is not yet
-traced."** This is confirmed still accurate: `PlayerMovementController.cs`'s
-per-frame method computes `MovementResult` (lines 2080-2226, the MTS side)
-and `LocalPlayerOutboundController.SendPreNetworkActions`/
-`SendPostNetworkPosition` (its own file, :50-144) split MTS-before-inbound
-vs AP-after-inbound exactly as retail's `UseTime` (0x006B3BF0, decomp
-699564-699583) does: `ShouldSendPositionEvent()→SendPositionEvent()` FIRST,
-then (separately, from input callbacks, not shown in `UseTime` itself)
-`SendMovementEvent`. TS-33's residual is real but narrow: it's an *ordering*
-question (does retail's per-frame input callback that calls
-`SendMovementEvent` run before or after that frame's `UseTime` AP check?),
-not a values/cadence question. Unchanged this session — still needs a cdb
-trace to close, not a code fix.
-
-### AP-30 — STALE register row (found this session)
-
-**FACT.** The register (`retail-divergence-register.md:153`) currently
-reads: *"AutonomousPosition diff cadence compares with epsilons (1 mm pos,
-1e-4 normal, 1 mm dist); retail's `Frame::is_equal` is an exact float
-compare... `src/AcDream.Runtime/Gameplay/PlayerMovementController.cs:1110`."*
-Both halves of this row are now wrong relative to current code:
-
-1. **Line citation is stale.** Line 1110 of `PlayerMovementController.cs`
-   today is inside `AttachAnimationRootMotionSource`'s parameter list — unrelated
-   code. The actual epsilon logic lives at `PlayerMovementController.cs:2234-2263`
-   (`ApproxFrameEqual`/`ApproxPlaneEqual`).
-2. **The epsilon claim is factually wrong about retail.** Read directly
-   from the named decomp: `Frame::is_equal` (`0x00424c30`, line 38461-38468)
-   calls `Vector3Math::AreEqual(origin, origin, 0.000199999995f)` and
-   `Frame::is_quaternion_equal` (0x00424c70, line 38472-38505), which
-   compares all four quaternion components against the **same
-   `0.000199999995f` (0.0002) epsilon** — not an exact bit compare.
-   Likewise `Plane::operator==` (`0x006b3dd0`, line 699713-699743) compares
-   `N.x`/`N.y`/`N.z`/`d` against the identical `0.000199999995f` epsilon.
-   `ApproxFrameEqual`/`ApproxPlaneEqual` in current acdream code (lines
-   2234-2263) use exactly `0.000199999995f` uniformly for both — i.e.
-   **acdream's current code already matches retail's real (epsilon, not
-   exact) comparison byte-for-byte**, and the code's own doc-comment says so
-   correctly ("Retail `Frame::is_equal` ... compares ... with a 0.0002-unit
-   epsilon"). The register row documents a bug that no longer exists.
-
-**Recommendation:** retire/correct AP-30 in the register (delete the row,
-or rewrite it to note the epsilon match is intentional retail parity, not a
-divergence) as a small housekeeping fix — no runtime behavior change
-needed, since the code is already correct.
-

-
-## 2. Inbound presentation
-
-### 2a. Interpolation catch-up rate — **DIVERGENT, high-severity** (found this session, per coordinator's byte-decode addendum)
-
-**FACT (P-review byte decode, 2026-07-30).** Retail's
-`InterpolationManager::adjust_offset`/`UseTime` (0x00555d30/0x00555f20)
-gates its catch-up-speed source on a **static flag**,
-`InterpolationManager::fUseAdjustedSpeed_` (`.data` at `0x0081f418`,
-initialized to `0x1` — confirmed directly, line 1102675):
-
-```
-if (fUseAdjustedSpeed_ == 0) catchUpBase = get_max_speed();          // DEAD by default
-else                          catchUpBase = get_adjusted_max_speed(); // the LIVE path
-catchUp = catchUpBase * 2.0f;   // MaxInterpolatedVelocityMod
-```
-(confirmed directly, `acclient_2013_pseudo_c.txt:353104-353123`).
-
-`CMotionInterp::get_adjusted_max_speed` (`0x00527d00`, line 305145-305156,
-read directly — BN drops the x87 return values into dead-looking
-statements, the same artifact class as `get_max_speed`'s ×4 dropout that
-UN-2 already resolved by disassembly) is **conditional on the entity's
-current interpreted forward command**:
-
- `forward_command != RunForward (0x44000007)` (i.e. standing, walking,
-  turning, sidestepping, backing up — anything but an actual run cycle):
-  returns the **bare run rate** (`InqRunRate`/`my_run_rate`), **no ×4**.
- `forward_command == RunForward`: returns
-  `interpreted_state.forward_speed ÷ current_speed_factor`, **× 4.0**
-  (`RunAnimSpeed`, `0x007c8918`) — per the coordinator's disassembly-level
-  decode (the BN pseudo-C alone drops this trailing multiply, matching the
-  established `get_max_speed`/UN-2 artifact pattern).
-
-**acdream's current code does not port `get_adjusted_max_speed` at all** —
-there is no `CurrentSpeedFactor`/`current_speed_factor` field anywhere in
-`MotionInterpreter.cs` (confirmed by grep, zero hits). Every call site that
-feeds the interpolation catch-up cap instead calls the **unconditional**
-`MotionInterpreter.GetMaxSpeed()` (`MotionInterpreter.cs:2632-2642`, itself
-a faithful, byte-verified port of retail's `get_max_speed` alone — always
-`runRate × RunAnimSpeed(4.0)`, regardless of forward_command):
-
- `src/AcDream.Runtime/Physics/RuntimeRemotePhysicsUpdater.cs:254`,
-  `:291`, `:685` (remote NPC/player catch-up)
- `src/AcDream.App/Physics/LiveEntityMotionRuntimeController.cs:174`
- `src/AcDream.App/Input/PlayerModeController.cs:328`
-
-**Consequence:** for any remote entity that is standing, walking, turning,
-sidestepping, or backing up (i.e. every state except actively running
-forward), acdream's catch-up cap is **exactly 4× retail's** (both use the
-×2.0 `MaxInterpolatedVelocityMod`, but acdream also always applies the ×4.0
-`RunAnimSpeed` that retail reserves for the RunForward-only branch). For a
-run-rate-2.94 character standing still: retail caps catch-up at
-2×2.94 ≈ **5.9 m/s**; acdream currently caps it at 2×2.94×4 ≈ **23.5 m/s**
-— a 4× overshoot. Only while the remote is genuinely in a `RunForward`
-cycle does acdream's flat ×4 approach retail's own (still not identical,
-since retail additionally normalizes by `current_speed_factor`, an
-unported field).
-
-This existed underneath a prior investigation (UN-2, resolved 2026-06-12,
-cited directly in `MotionInterpreter.cs:2601-2630`) that correctly
-byte-verified the ×4.0 constant *inside* `get_max_speed`, but did not catch
-that `get_max_speed` itself is the **dead default branch** — retail's real
-call site always takes `get_adjusted_max_speed`, which only applies that
-×4 conditionally. This is a strong root-cause candidate for the "remote
-catch-up feels too fast/twitchy for non-running remotes" symptom family
-(#41 blips, #165 wall-penetration-before-stop) that the same doc-comment
-explicitly says to look elsewhere for — this audit's finding redirects that
-search back to this exact seam.
-
-**Recommendation (report-only — no fix applied):** port
-`CMotionInterp::get_adjusted_max_speed` as a new `MotionInterpreter` method
-(needs `current_speed_factor`, currently absent — a new tracked field,
-citing `0x00527d00`/line 305145), and switch every catch-up-cap call site
-above from `GetMaxSpeed()` to the new adjusted accessor, gated by the
-(retail-fixed-true) `fUseAdjustedSpeed_` semantics — i.e. always call the
-adjusted variant, since retail's own flag is always on. This is the
-single highest-value fix candidate in this audit.
-
-### 2b. Snap / teleport thresholds — two distinct constants, both present
-
-**FACT.** Retail has two separate thresholds, and acdream has ported both
-correctly:
-
-| Constant | Retail value | Retail site | acdream value | acdream site |
-|---|---|---|---|---|
-| Hard routing snap (give up on interpolation entirely, `MoveOrTeleport`) | **96.0 m** | `CPhysicsObj::MoveOrTeleport` 0x00516330, line 284342-284361 | Not separately named in `InterpolationManager.cs` — this gate lives upstream, at the physics dispatch layer (`RuntimeRemotePhysicsUpdater`/teleport handling), not audited line-by-line this session; flagged as **needs a follow-up grep to confirm the 96 m constant is present at the equivalent acdream call site** (not found during this pass — see gap catalog). | — |
-| Enqueue-time "far jump, pre-arm blip" (`AutonomyBlipDistance`) | **100 m outdoor / 20 m indoor** per prior cdb live-attach (project's own 2026-05-0x capture) — the *decomp* constant itself (`GetAutonomyBlipDistance`, 0x0050eb70) is BN-garbled and not independently re-derivable from static text alone this session (**INFERENCE**, cdb-sourced not decomp-sourced) | `CPhysicsObj::GetAutonomyBlipDistance` 0x0050eb70 | `AutonomyBlipDistance = 100.0f` (`InterpolationManager.cs:99`), comment explicitly notes "indoor is 20 m" as a known-but-unported distinction | `InterpolationManager.cs:99` |
-
-**Verdict: Parity** for the enqueue-time 100 m outdoor constant (matches
-the project's own prior cdb finding); the indoor-20m variant is
-**Divergent/incomplete** — acdream uses a flat 100 m regardless of
-indoor/outdoor, an existing known gap already flagged in the code's own
-comment (not a new finding, confirmed still present).
-
-### 2c. Position-history queue depth — Parity
-
-**FACT.** Retail: 20 entries (`0x14`), head-evicted on overflow, confirmed
-directly at `InterpolateTo` line 353004-353021. acdream:
-`QueueCap = 20` (`InterpolationManager.cs:49`), enforced identically
-(`Enqueue`, :254-256, `RemoveFirst()` on cap). **Parity.**
-
-### 2d. Stall/give-up mechanics — Parity
-
-**FACT**, all four constants cross-checked directly against the decomp
-this session and via the subagent's independent read of
-`InterpolationManager.cs`:
-
-| Constant | Retail (line) | acdream (`InterpolationManager.cs`) |
-|---|---|---|
-| Stall check window | 5 frames (353146) | `StallCheckFrameInterval = 5` (:79) |
-| Min progress distance | 0.20 m (353185-353190) | `MinDistanceToReachPosition = 0.20f` (:67) |
-| Min progress fraction | 0.30 (353172-353177) | `StallProgressMinFraction = 0.30f` (:86) |
-| Fail-count blip threshold | `> 3` (353270) | `StallFailCountThreshold = 3` (:92), fires at 4+ |
-
-**Verdict: Parity.**
-
-### 2e. TS-44 sticky-gated enqueue suppression
-
-Not inside `InterpolationManager.cs` itself — lives in the consumer,
-`src/AcDream.App/Physics/LiveEntityNetworkUpdateController.cs:1637-1643`.
-Suppresses a raw `UpdatePosition`-driven snap for an NPC currently
-sticky-attached to a target (`PositionManager.GetStickyObjectId() != 0`),
-bounded by the ~1 s sticky lease; register TS-44 is **narrowed, not
-retired** (per `docs/ISSUES.md` 2026-07-07 pass). User-visible effect:
-while a monster is sticky-melee-locked onto a target, an incoming server
-position correction that would otherwise snap the NPC is suppressed and
-the sticky steering keeps driving it instead — server truth reasserts on
-the first UpdatePosition after the lease expires. This is a deliberate,
-already-registered adaptation, not a newly found gap.
-
-### 2f. MoveToRunRate consumption
-
-**FACT.** Wire-parsed in `CreateObject.cs:269-296` (`ServerMotionState`
-field) and consumed at `LiveEntityNetworkUpdateController.cs:323,433` and
-`LiveEntityMotionRuntimeController.cs:394`. A pre-existing, separately
-tracked gap (M13 plan doc `docs/research/2026-07-03-r4-moveto/r4-port-plan.md:87`)
-notes `MoveToRunRate` feeds the PlanMoveToStart seed but not
-`MotionInterpreter.MyRunRate` directly during a live moveto, so
-`apply_run_to_command`'s speed scale can use a stale rate mid-MoveTo. Not
-re-litigated further this session — flagged as a known, already-filed item
-in the gap catalog below (not new).
-
-### 2g. Walk↔Run mid-hold promote/demote render fidelity
-
-**Issue #39** — "Run↔Walk cycle transition not visible on observed player
-remotes." **Status confirmed directly this session: CLOSED 2026-07-02**
-(`docs/ISSUES.md:7107`). The original 2026-05-06 root-cause ("ACE goes
-silent on HoldKey-only toggle") was refuted by a 2026-07-02
-three-oracle-plus-live-capture re-investigation
-(`docs/research/2026-07-02-inbound-motion-deviation-map.md`, §S0): retail
-DOES send a fresh MoveToState on HoldRun toggle while moving, and ACE DOES
-rebroadcast it; the refinement machinery #39 built to compensate for the
-(non-existent) gap was deleted (commit S5) after it caused spurious
-Ready↔Run animation thrash. **CLAUDE.md's phrasing that this is an open
-uncertainty ("ACE's behavior on relay is uncertain") is stale relative to
-the ISSUES.md record** — worth a small doc correction, not a code gap.
-

-
-## 3. MoveTo/TurnTo parameters
-
-Retail's `MovementParameters` ctor (`0x00524380`, decomp line 300510-300534,
-struct verbatim at `acclient.h:31453-31465`) vs acdream's
-`MovementParameters.cs` (already cites the same address):
-
-| Field | Retail default | acdream default | Cite | Verdict |
-|---|---|---|---|---|
-| `MinDistance` | 0.0 | 0f (`:164`) | 300510-300534 | Parity |
-| `DistanceToObject` | 0.6 m | 0.6f (`:161`) | same | Parity |
-| `FailDistance` | FLT_MAX (3.40282347e+38) | `float.MaxValue` (`:173`) | same | Parity |
-| `Speed` | 1.0 | 1f (`:170`) | same | Parity |
-| `WalkRunThreshhold` | **15.0 m** | 15f (`:179`) | same | Parity — and acdream's own comment explicitly flags the ACE-divergence trap (ACE uses 1.0) and refuses to copy it |
-| `CanCharge` (bitfield 0x10) | **clear (false)** | `false` (`:102`) | same | Parity — same explicit ACE-divergence-trap comment (ACE sets it true by default) |
-| `HoldKeyToApply` | `HoldKey_Invalid` | `HoldKey.Invalid` (`:185`) | same | Parity |
-
-**Verdict: full parity.** acdream's `MovementParameters.cs` is a verbatim,
-already-well-cited port with correct, explicit call-outs of two known
-ACE-vs-retail divergence traps (`CanCharge`, `WalkRunThreshhold`) that it
-deliberately does NOT copy from ACE. No gap found here.
-
-### Turn/arrival thresholds beyond the ctor
-
- `HandleMoveToPosition`'s aux-turn deadband: **20°/340°**
-  (`MoveToManager.cs:1057`, retail `0x00529d80` line 307187-307438) —
-  matches the retail function it cites; not independently re-derived from
-  raw bytes this session (**INFERENCE** on the exact retail constant, but
-  the citation chain is pre-existing and was not contradicted by anything
-  found this session).
- `BeginTurnToHeading`/`HandleTurnToHeading` epsilon-snap logic
-  (`MoveToManager.cs:819-873`, `:1155-1203`) cites retail addresses
-  `0x00529b90`/`0x0052a0c0` directly; the code's own comments flag two
-  retail quirks as deliberately preserved: `FailProgressCount` is
-  write-only in retail (no give-up threshold exists — do not invent one),
-  and `HandleMoveToPosition` has **no** `set_heading` call (ACE's
-  "sync for server tickrate" addition is explicitly NOT ported). Both
-  read as correct, deliberate non-divergences.
-
-### MinDistance vs FailDistance semantics
-
-**FACT** (both retail and acdream, per direct decomp read this session and
-independent MoveToManager.cs read): both `MoveToObject` and
-`MoveToPosition` share one `movement_params`/`Params` struct and one
-handler. `MinDistance`/`DistanceToObject` gates *arrival* (current distance
-to target this tick); `FailDistance` gates *give-up* against **total
-distance traveled since the move began**, defaulting to FLT_MAX so it is
-effectively inert unless a caller tightens it. No object-vs-position
-asymmetry exists in either client. **Parity.**
-
-### AP-23 — pickup/use-radius heuristic (current scope)
-
-Register row (`retail-divergence-register.md:148`): an invented per-type
-radius bucket (3 m creatures / 2 m doors-lifestones-portals-corpses / 0.6 m
-rest) for close-range gating. **Narrowed 2026-07-25 (R5-V3):** the
-speculative install now threads the target's real Setup
-radius/height (`GetSetupCylinder`) and the player's real radius; only the
-bucket bounds remain invented, and Use itself was retired from the
-speculative-moveto seam entirely (sends immediately now). Located at
-`src/AcDream.App/Interaction/WorldSelectionQuery.cs:78-83` (constants),
-`:490-498` (`GetUseRadius`). **One live consumer still cites this seam as
-its root mechanism**: `docs/ISSUES.md` issue at line 3825-3826 (2026-07-05,
-door-Use-swallowed, HIGH severity), whose resolution is explicitly folded
-into Campaign P's physics-parity visual matrix scenario 8
-(`docs/plans/2026-07-30-physics-parity-visual-matrix.md`) — i.e. this is
-already tracked and pending the user's visual gate, not a newly found gap.

-## 4. Autorun + mouse semantics
-
-### Retail mechanics (all FACT, byte-read this session)
-
- **Toggle entry point:** `CommandInterpreter::ToggleAutoRun` (`0x006b3cc0`,
-  line 699625-699631): `SetAutoRun(auto_run==0, 1)`. Bound via
-  `CommandInterpreter::HandleKeyboardCommand` (`0x006b3690`, line
-  699262-699289) on keyboard command `0x90000c7`: reads an **optional
-  trailing float from the same keybind's argument stream** as
-  `autorun_speed` (defaults to **1.0** if the keybind carries no extra
-  argument — confirmed this is the stock case: the retail keymap's
-  `MovementRunLock [ "" [ 0 DIK_Q ] ]` entry carries no such argument).
- **Default key:** `Q` — confirmed identical in
-  `docs/research/named-retail/retail-default.keymap.txt:105` and
-  acdream's `KeyBindings.RetailDefaults():174`.
- **What "on" actually sends:** `CommandInterpreter::ApplyCurrentMovement`
-  (`0x006b3430`, line 699146-699183): when `auto_run != 0`, retail
-  unconditionally calls
-  `MovePlayer(WalkForward(0x45000005), 1, autorun_speed, SetHoldKey=1, HoldKeyToApply=1(Run))`
-  — **autorun ALWAYS forces `HoldKey.Run`**, hard-coded, independent of any
-  live walk/run toggle state. Since stock `autorun_speed` defaults to 1.0
-  and the hold key is forced Run, **retail's default autorun always runs**
-  (WalkForward+HoldKey.Run, which ACE/observers see as RunForward), never
-  walks, regardless of whether the player has Shift/walk-mode held at
-  toggle time or afterward.
- **Cancel conditions, two independent mechanisms:**
-  1. `CommandInterpreter::HandleNewForwardMovement` (`0x006b3d60`, line
-     699672-699676): **any fresh Forward key press cancels autorun**
-     (`SetAutoRun(0, 1)`).
-  2. `CInputManager::ActivateActionKey` (`0x00432650`, line 699243-699258
-     region, specifically 699496-699502): on a genuine key-down edge
-     (not a repeat) for action IDs `0x29`/`0x2a`/`0x2b`, calls
-     `CInputManager::TurnOffRunLock` (`0x004325e0`, line 699424-699442),
-     which removes the `MovementRunLock` action state and fires its
-     release-equivalent listener callback. (The exact identity of actions
-     `0x29`-`0x2b` as raw `CInputManager` action-ID ordinals was not
-     resolved from static text this session — **INFERENCE** that they are
-     Backward/StrafeLeft/StrafeRight, based on process-of-elimination
-     against `HandleNewForwardMovement`'s separate, explicit Forward-only
-     handling.)
-  3. Also unconditionally cleared on `LoseControlToServer`,
-     `PlayerTeleported`, `PlayerIsDead`-detected `MovePlayer` calls, and
-     `HandleKeyboardCommand`'s own `LoseKeyboardFocus`/death paths.

-### acdream mechanics
-
-`RuntimeLocalPlayerMovementState.cs` (`Execute(ToggleRunLock)`, :116-119;
-`CancelAutoRun()`, :148-156) + `DispatcherMovementInputSource.cs` (:48-96):
-
- Default key: **Q** — matches (`KeyBindings.cs:174`).
- **On:** `Forward: forward || AutoRunActive` (:65) — autorun simply forces
-  the `Forward` boolean true; `Run: !walking` (:71) is evaluated **live,
-  every poll**, from whatever `InputAction.MovementWalkMode` (Shift) is
-  currently held — **independent of autorun state**.
- **Cancel set:** `HandlePressedAction` (:80-96) cancels autorun on Press
-  of `{MovementBackup, MovementStop, MovementStrafeLeft, MovementStrafeRight}`
-  only.
-
-### Verdicts
-
-| Behavior | Retail | acdream | Verdict |
-|---|---|---|---|
-| Default key | Q | Q | Parity |
-| Pace while autorunning | **Always Run** (hard-forced `HoldKey.Run`, independent of walk-mode toggle) | **Follows the live `MovementWalkMode` toggle** — if the user has Shift/walk-mode held (or toggled) while or after engaging autorun, autorun walks instead of runs | **Divergent.** Confirmed by direct read of `DispatcherMovementInputSource.cs:71` (`Run: !walking`, unconditioned on `AutoRunActive`) against retail's `ApplyCurrentMovement` autorun branch (`SetHoldKey=1, HoldKeyToApply=1` hard-coded, `0x006b3486`). |
-| Cancel on Backward/Strafe | Yes (input-layer `TurnOffRunLock`, **INFERENCE** on exact action IDs) | Yes, explicit (`MovementBackup`, `MovementStrafeLeft`, `MovementStrafeRight`) | Parity (functional match) |
-| Cancel on Stop key | Not separately identified in retail's cancel set this session (no explicit S/Stop-key cancel site found; likely folds through `auto_run`/`transient_state` reset elsewhere) | Yes, explicit (`MovementStop`) | Likely parity, low-confidence on the retail side |
-| **Cancel on fresh Forward press** | **Yes** — `HandleNewForwardMovement` explicitly cancels autorun on every new W press (`0x006b3d60`) | **No** — `MovementForward` is absent from `HandlePressedAction`'s cancel list (:86-91); architecturally reachable (the same Press edge already drives `CombatAttackInputFrameAdapter.HandleMovementInput`'s abort-for-movement check, `GameplayInputFrameController.cs:24-39`) but not wired to `CancelAutoRun()` | **Divergent, confirmed gap.** In acdream, pressing W while autorunning is currently a no-op (autorun stays latched, `Forward` was already true); in retail, the same press explicitly drops autorun and hands control back to the held key. |
-| Mouse-look interaction with autorun | No evidence found of a direct interaction; mouse-look drives its own `TurnLeft`/`TurnRight` channel independent of `auto_run` | Same — mouse-look turn channel (`_activeInputTurnCommand`) is independent of `AutoRunActive` | Parity (no interaction expected on either side) |
-| Both-mouse-buttons-run | No evidence found of a distinct "both mouse buttons = run forward" binding in the decompiled `CommandInterpreter`/`CInputManager` text searched this session | Not implemented (no such binding in `KeyBindings.RetailDefaults()`) | **Ruled out as a feature** — this session found no retail mechanism for it, so acdream's absence is not a gap. (If the user recalls this from live retail play, it would warrant a targeted cdb trace on `IInputActionCallback`/mouse-button handlers; not found in the static decomp searched here.) |

-## 5. Turn-rate composition
-
-**FACT**, direct decomp read this session, `CMotionInterp::apply_raw_movement`
-(`0x005287e0`, line 305817-305834) → three independent
-`adjust_motion(forward)`, `adjust_motion(sidestep)`, `adjust_motion(turn)`
-calls → `apply_interpreted_movement` (`0x00528600`, line 305713-305788)
-dispatches `DoInterpretedMotion` **separately** per axis.
-
- **No cross-axis normalization exists in retail.** Forward, sidestep, and
-  turn are fully independent scalar channels; there is no diagonal-movement
-  magnitude clamp (no "moving diagonally isn't faster than moving straight"
-  logic anywhere in this pipeline) — retail "naively adds commands," to use
-  the literal reading of `apply_interpreted_movement`'s three sequential,
-  unconditional `DoInterpretedMotion` calls.
- **Turning while moving backward:** confirmed **no interaction** — the
-  backward `-0.65×` scale (`adjust_motion`'s `0x45000006→WalkForward`
-  canonicalization) only touches the forward channel; the turn channel's
-  own `adjust_motion(turn)` call and its 1.5× run-turn factor are
-  processed independently with zero shared state.
- **Order of operations relative to dt:** the 1.5× turn multiplier (and
-  the 1.248× sidestep scale, and the ×4.0/`current_speed_factor` catch-up
-  math) all operate on the pre-integration **speed scalar**; dt-integration
-  happens downstream in physics, not inside `adjust_motion`/
-  `apply_run_to_command`. So "run-turn factor before or after dt scaling"
-  is moot — it's applied to the same speed value physics later multiplies
-  by dt, in both clients.
-
-**acdream's port** (`MotionInterpreter.cs`, `adjust_motion` :1290-1321,
-`apply_raw_movement`-equivalent :1386-1424) mirrors this structure exactly:
-three independent `adjust_motion` calls per axis (:1416, :1420, :1424), no
-cross-axis clamp anywhere in the surrounding code, and the code's own
-comment (:1268-1271) explicitly documents the same ordering subtlety
-retail has (sign-flip on canonicalization happens BEFORE the 1.248
-sidestep scale, so the net multiplier for SideStepLeft is `-1.248×speed`,
-not `-1×(1.248×speed)` — same value algebraically, but the comment shows
-the port tracked retail's actual operation order, not just its result).
-
-**Verdict: full parity.** No combined-input normalization gap found on
-either side (neither client has one) — this is a "ruled out" item, not an
-open question. Backward+turn and strafe+turn combinations have no special
-case in retail and none in acdream, matching.

-## 6. Wire-format cross-check: holtburger + Chorizite
-
-### RawMotionState / MoveToState / AutonomousPosition bit layout — three-way parity
-
-**FACT.** `references/holtburger/crates/holtburger-protocol/src/messages/movement/types.rs:45-61`
-(`RawMotionFlags` bitflags) is bit-for-bit identical to acdream's
-`RawMotionStatePacker.cs:44-55` flag constants (0x001 CurrentHoldKey through
-0x400 TurnSpeed, `num_actions` in bits 11+ via
-`packed_flags >> 11` matching acdream's `NumActionsShift = 11`), and both
-match the named-retail `RawMotionState::Pack` (0x0051ed10) bitfield this
-project already ported. `MoveToStateActionData`
-(`.../movement/actions.rs:9-18`) field order (raw_motion_state, position,
-4× u16 sequence, one trailing byte) matches acdream's `MoveToState.Build`
-call shape exactly, including the trailing
-`(standingLongjump?2:0)|(contact?1:0)` byte (holtburger's
-`contact_long_jump: u8`, same slot). `AutonomousPositionActionData`
-(:141-149) matches `AutonomousPosition.Build` field-for-field.
-
-Independently, holtburger's own `AUTONOMOUS_POSITION_HEARTBEAT_INTERVAL`
-(`crates/holtburger-core/src/client/movement/common.rs:22`) is
-**`Duration::from_secs(1)`** — a third independent confirmation (after
-retail's decomp ctor default `0x3ff00000`=1.0 at line 699783, and acdream's
-`HeartbeatInterval = 1.0f`) that the AP heartbeat is exactly 1 second across
-all three. **Parity, three-way confirmed.**
-
-### Jump packet — acdream matches retail; BOTH holtburger and Chorizite are wrong here
-
-**FACT, byte-verified this session.** Retail's `JumpPack::Pack`
-(`0x00516d10`, decomp line 284915-284967, read directly) writes, in exact
-order: `extent` (f32) → `velocity.x/y/z` (f32×3) →
-**`this->position.vtable->Pack(...)`** (a full `Position` pack: objcell_id
-+ frame origin + quaternion) → `instance_timestamp`/`server_control_timestamp`/
-`teleport_timestamp`/`force_position_ts` (u16×4) → 4-byte align. This
-matches the `JumpPack` **constructor** signature
-(`0x00516c70`, line 284887: `float, Vector3 const*, Position const*, u16×4`)
-exactly — Position genuinely is part of the wire bytes, not just a
-constructor-time convenience.
-
-acdream's `JumpAction.Build(gameActionSequence, extent, velocity, cellId,
-position, rotation, instanceSequence, serverControlSequence,
-teleportSequence, forcePositionSequence)` (called from
-`LocalPlayerOutboundController.cs:73-84`) matches this exactly — this was
-already the subject of a correction (memory: "D4 `JumpAction` = retail
-`JumpPack` (extent·velocity·Position·4 ts); spurious objectGuid/spellId
-removed, Position now packed").
-
-By contrast:
- **holtburger's `JumpActionData`** (`.../movement/actions.rs:73-82`) has
-  **no `Position` field at all** — instead `extent`, `velocity`, 4×
-  sequence, then `object_guid: Guid` and `spell_id: u32`. This is the
-  *pre-correction* shape acdream itself used to have before the D4 fix
-  (per the same memory note) — i.e. holtburger's Jump model reproduces the
-  same historical mistake acdream already found and fixed via the named
-  decomp.
- **Chorizite's `JumpPack.generated.cs`** (`Types/JumpPack.generated.cs:22-83`)
-  has **neither Position nor object_guid/spell_id** — just `Extent`,
-  `Velocity`, and the 4 sequence ushorts, then straight to 4-byte
-  alignment. Also missing the Position bytes.
-
-**Conclusion: acdream's Jump packet is the retail-correct one; do not use
-holtburger's or Chorizite's Jump models as a tiebreaker for this specific
-packet** — both diverge from the byte-verified retail shape in the same
-direction (omitting Position), and holtburger additionally invents
-object_guid/spell_id fields that do not exist on the wire. This is a
-genuine finding worth remembering for future cross-reference work on this
-one packet (not something to act on in acdream — acdream is already
-correct), and is exactly the kind of case the project's reference-hierarchy
-rule anticipates ("the intersection of the relevant references is almost
-always the truth... a single reference can be misleading") — here the
-*retail decomp itself*, not the intersection, was the tiebreaker, since two
-of three references independently share the same divergence.

-## 7. Ranked gap catalog
-
-1. **[HIGH] Interpolation catch-up cap is 4× too fast for any non-running remote (§2a).**
-   `MotionInterpreter` never ported `get_adjusted_max_speed`
-   (`0x00527d00`) or `current_speed_factor`; every catch-up-cap call site
-   (`RuntimeRemotePhysicsUpdater.cs:254,291,685`,
-   `LiveEntityMotionRuntimeController.cs:174`, `PlayerModeController.cs:328`)
-   uses the always-×4 `GetMaxSpeed()` instead of the conditional accessor
-   retail's own `fUseAdjustedSpeed_=1` static makes the *only* live path.
-   Root-cause candidate for observed remote catch-up feeling too
-   fast/twitchy outside full sprint. **Recommended fix order: first**,
-   since it's concrete, well-cited, and plausibly explains existing
-   symptom reports (#41/#165 family) the project has been chasing under
-   other theories.
-2. **[MEDIUM] Autorun always inherits the live walk/run toggle instead of always forcing Run (§4).**
-   `DispatcherMovementInputSource.cs:71` computes `Run: !walking` every
-   poll, unconditioned on `AutoRunActive`; retail's `ApplyCurrentMovement`
-   hard-forces `HoldKey.Run` for the entire duration of an autorun latch
-   regardless of walk-mode state. User-visible: toggling walk-mode while
-   autorunning in acdream can make it walk; retail autorun never walks
-   (absent a custom keybind speed argument, which the stock keymap doesn't
-   carry).
-3. **[MEDIUM] Autorun does not cancel on a fresh Forward (W) press (§4).**
-   `HandlePressedAction`'s cancel set omits `InputAction.MovementForward`;
-   retail's `HandleNewForwardMovement` explicitly cancels on every new W
-   edge. Currently a silent no-op difference (autorun stays latched) that
-   is architecturally trivial to close — the same Press edge is already
-   routed through the pipeline for the unrelated combat-abort check.
-4. **[LOW, doc-only] AP-30 register row is stale (§1).** Both its file:line
-   citation and its epsilon claim about retail no longer match reality —
-   the code already matches retail's real (epsilon-based, not exact)
-   `Frame::is_equal`/`Plane::operator==` comparison. Recommend
-   retiring/correcting the row; zero runtime risk either way.
-5. **[LOW] Indoor `AutonomyBlipDistance` uses a flat 100 m regardless of indoor/outdoor (§2b).**
-   Already flagged in the code's own comment as a known simplification (cdb
-   sourced 20 m indoor vs 100 m outdoor); not a new finding, but grouped
-   here since it's the one open item in an otherwise clean interpolation
-   audit.
-6. **[LOW, needs follow-up not fix] Confirm the 96 m hard-teleport-snap threshold's acdream equivalent (§2b).**
-   This session did not locate the acdream call site that mirrors retail's
-   `MoveOrTeleport` 96 m routing gate (`0x00516330`) — flagged as an
-   unresolved research gap, not a confirmed divergence. Worth a follow-up
-   grep for wherever acdream decides "too far to interpolate, snap
-   instead" at the physics-dispatch layer (outside `InterpolationManager.cs`
-   itself).
-7. **[INFO, no action] CLAUDE.md's "ACE's Run↔Walk relay behavior is uncertain" phrasing is stale (§2g).**
-   Issue #39 closed 2026-07-02 with the opposite finding (retail does send
-   a fresh MoveToState on HoldRun toggle; ACE does relay it). Small doc
-   correction candidate, zero code impact.
-8. **[INFO, no action] Two of three wire-format oracles have a wrong Jump packet model (§6).**
-   holtburger and Chorizite both omit `Position` from their Jump packet
-   type; acdream's is byte-verified correct. No action needed on acdream's
-   side — recorded so a future cross-reference pass doesn't get misled by
-   holtburger/Chorizite's shared mistake on this one packet.

-
-The property/capacity shape matches acdream's

-`InventoryController.RefreshBurden()` pattern (Strength attribute + prop 0xE6
-aug + prop 5 EncumbranceVal, falling back to `SumCarriedBurden` when the wire
-value is absent). A 2026-07-31 connected gate exposed one omitted retail
-detail: `InqAttribute` returns the enchantment-adjusted attribute, while all
-three acdream burden consumers still read raw `AttributeValue.Current`.
-Issue #272 corrects them to `LocalPlayerState.GetEffectiveAttribute(Strength)`
-and invalidates burden on the canonical `Spellbook.EnchantmentsChanged` edge.
-**`AcDream.Core.Items.BurdenMath`
-(`EncumbranceCapacity`/`LoadRatio`/`LoadModifier`) is the SAME formulas at
-the SAME addresses.** P1's `EncumbranceSystem` (Physics-namespaced, for
-citation clarity next to `MovementSystem`) delegates to `BurdenMath` rather
-than re-deriving — one source of truth, no drift between the burden HUD and
-movement physics.

-## 3. CanJump (0x00591b50, pc 412907) — X87 MUSH, POLARITY RESOLVED BY PLAUSIBILITY
-
-```c
-CanJump(this, extent):
-    load = 0
-    if (InqLoad(this, &load) != 0):
-        p = <fcompp load, 2.0f; fnstsw; test ah,0x05>   // "load < 2.0" per BN's own
-                                                          // asserted C0 subexpression
-        if (!p) return 1
-    return 0
-```
-
-Literal BN reading: `if (!p) return 1` = "if load is NOT < 2.0 (i.e. >= 2.0),
-return CAN-jump; otherwise CANNOT". That is backwards from every other
-retail-movement fact we have (LoadMod's own floor sits at 2.0; the campaign's
-connected-matrix acceptance is "≥200% barely moves/jumps", not "can only jump
-when overloaded"). This is the documented BN "bitfield mush" artifact class
-(`feedback_bn_decomp_field_names.md`) — the flag-synthesis is unreliable for
-the FOLLOWING `test ah,mask` interpretation even when the preceding
-subexpression is trustworthy.
-
-**Resolution (register row UN-8, see §6):** `CanJump` returns `load < 2.0`
-(can jump under 200% burden; refused at/above it) — the polarity a normal
-AC player's lived experience requires, and the one that makes CanJump's own
-threshold coincide with `LoadMod`'s floor. ACE gives no tiebreaker
-(`WeenieObject.CanJump` is an unconditional `return true` stub — never
-ported burden gating at all). Ghidra MCP was down for this slice; flagged
-for a future confirmation pass, not blocking this port.
-
-## 4. JumpStaminaCost (0x00591b90, pc 412949) — FULLY READABLE
-
-```c
-CACQualities::JumpStaminaCost(this, extent, &costOut):
-    load = 0
-    if (InqLoad(this, &load) == 0) return 0
-    pk = 0
-    pkStatus = InqInt(this, PROPERTY_INT_PLAYER_KILLER_STATUS=0x86, default=8)
-    if (pkStatus == 4 || pkStatus == 0x40):          // PK / PKLite
-        pkTimestamp = InqFloat(this, PROPERTY_FLOAT_LAST_PK_ATTACK_TIMESTAMP=0x91)
-        if (pkTimestamp is present && !(pkTimestamp + 20.0 < Timer::cur_time)):
-            pk = 1                                    // PK timer active (<20s since last PK act)
-    *costOut = MovementSystem::JumpStaminaCost(extent, load, pk)
-    return 1        // ALWAYS true once InqLoad succeeds — no affordability
-                     // check lives in this function.
-```
-
-**Key finding:** retail's `CanQualities::JumpStaminaCost` NEVER returns false
-(except when `InqLoad` itself fails, which doesn't happen for a real player).
-`jump_is_allowed`'s `if (!WeenieObj.JumpStaminaCost(...)) return 0x47` branch
-(the "refusal" path our own `MotionInterpreter.cs` already ports verbatim,
-W0-pins.md A2) is real retail *machinery*, but `CACQualities` never actually
-exercises the refusing side of it. **"Refused jump" does not happen via this
-mechanism in retail — only "weak jump" (see §5).** P1 ports
-`JumpStaminaCost` to always return `true` with the REAL computed cost
-(retiring the TS-5 zero-cost stub), matching this decomp exactly.
-
-The `pk` flag is `PlayerKillerStatus`/`LastPkAttackTimestamp` — TS-23's
-exact scope (P3, not P1). P1 hardcodes `pk: false` at the one new call site
-(`PlayerWeenie.JumpStaminaCost`) and documents the dependency against TS-23
-rather than re-implementing PK parsing here.

-## 5. InqRunRate (0x00592800, pc 413824) / InqJumpVelocity (0x00592980, pc 413902) — FULLY READABLE
-
-Both functions share one shape (Run uses skill id 0x18=24, Jump uses 0x16=22):
-
-```c
-InqRunRate(this, &rateOut):
-    load = 1.0
-    if (InqLoad(this, &load) == 0) return 0
-
-    currentStamina = 0
-    if (AttributeCache::InqAttribute2nd(attribCache, ATTR2ND_STAMINA=4, &currentStamina) == 0)

-
-    skill = InqSkillBaseLevel(this, SKILL_RUN=0x18)     // formula-bonus + init + ranks

-    EnchantSkill(this, 0x18, &skill)                    // vitae * skill-enchantments, floor@0.5, truncate
-    if (PropertyInt 0x146 > 0) skill += 5              // Jack of All Trades
-    if (skill is specialized) skill += 2 * max(PropertyInt 0x158, 0)
-
-    if (currentStamina == 0) skill = 0                  // THE stamina-gates-movement mechanism
-
-    *rateOut = MovementSystem::GetRunRate(load, skill, 1.0)
-    return 1
-```
-
-`InqJumpVelocity` is identical but for skill id 0x16=22, and finishes with
-`sqrt(MovementSystem::GetJumpHeight(load, skill, extent, 1.0) * 19.6)` (pc
-413975, matching `GetJumpVZ`'s existing sqrt call already in
-`MotionInterpreter.cs`/`PlayerWeenie.cs` — unchanged).
-
-**Answering the plan's question — "which skill level does retail feed?"**
-Neither raw base nor a separately-cached value: retail re-derives, on every
-query, `EnchantSkill(baseSkill)` where `EnchantSkill` (`CEnchantmentRegistry::
-EnchantSkill` 0x005947b0, pc 416240, FULLY READABLE) is:
-
-```c
-EnchantSkill(registry, skillId, &valueInOut):
-    value = *valueInOut                       // base skill (formulaBonus+init+ranks)
-    if (registry._vitae != null):
-        value = Enchant(registry._vitae, value)      // vitae multiplier FIRST
-    matching = CullEnchantmentsFromList(mult_list, category=SKILL=0x10, skillId)
-             ++ CullEnchantmentsFromList(add_list,  category=SKILL=0x10, skillId)
-    for each e in matching: value = Enchant(e, value)  // per-record mult OR add
-    if (value < 0.5) value = 0                          // floor
-    *valueInOut = (int)value                            // truncate (ftol2)
-    return ...
-```
-
-`CEnchantmentRegistry::EnchantAttribute2nd` (0x00594670, pc 416169, the
-vitals path our `EnchantmentMath.GetMod` already ports for
-`LocalPlayerState.GetMaxApprox`) applies `_vitae` in the **identical**
-position (first, before the mult/add lists) — confirming our existing vitae
-representation (`ActiveEnchantmentRecord.Bucket == 4`, a StatModType `Vitae`
-flag `0x00800000` classified in `GameEventWiring.ClassifyLiveEnchantmentBucket`)
-is the right vehicle: **P1 reuses it unmodified**, adding a sibling
-`EnchantmentMath.GetSkillMod` (filtered by `StatModType & Skill(0x10) != 0`
-instead of the vitals' implicit attribute2nd filter) rather than inventing a
-new vitae channel. This satisfies "vitae/enchant-adjusted effective run/jump
-skill... reading vitae + relevant skill enchantments from the M3
-active-effect state" without a general effective-skill engine — the only new
-code is the type-flag filter and the skill-id key.
-
-**2026-07-31 #268 closeout:** the previously bounded augmentation terms are
-now ported in shared `PlayerSkillMath`, after a complete read of
-`CACQualities::InqSkill @ 0x00592660`. The exact order matters:
-
-1. intrinsic formula/init/ranks;
-2. positive property 0x16D plus the exact category +10 switch;
-3. `EnchantSkill`;
-4. property 0x146 contributes +5 when positive;
-5. specialized skills receive `2 × max(property 0x158, 0)`.
-
-The character panel and Runtime movement both consume this one Core
-calculation. AP-127 is retired. The apparent current-stamina-copy residual
-does not create an independently reachable effect for ordinary stat
-enchantments: current and maximum stamina use distinct secondary-attribute
-keys, and a max-stamina enchantment cannot turn zero current stamina nonzero.
-
-## 6. GetRunRate / GetJumpHeight / JumpStaminaCost formula bodies (MovementSystem, pc 695958+)
-
-`GetRunRate` (0x006b0950) and the `arg3!=0` (PK) branch of `JumpStaminaCost`
-(0x006b0a40) have their GENERAL-CASE arithmetic entirely dropped by BN (only
-the `EncumbranceSystem::LoadMod`/`800`-skill-compare calls and the `arg3==0`
-ceil expression survive uncollapsed — the same information-loss class as the
-x87 mush, just total rather than partial). **ACE is the cross-reference
-tiebreaker for those two spots** (`references/ACE/Source/ACE.Server/Physics/
-Animation/MovementSystem.cs`), matching this exact acdream port's ORIGINAL
-citation style (`PlayerWeenie.cs`'s pre-P1 doc comments already said
-"decompiled + ACE MovementSystem" for these two formulas — nothing new here,
-just now with a named-decomp address alongside):
-
- `GetRunRate(load, skill, scaling) = skill==800 ? 18/4 : ((LoadMod(load) * (skill/(skill+200)*11) + 4) / scaling) / 4` —
-  **§12c correction (#266, 2026-07-30): the 800 branch is EXACT EQUALITY,
-  not `>=`.** Raw byte decode of 0x006b0950 (PDB-paired binary):
-  `fild skill; fcom [0x00803b94 = 800f]; fnstsw ax; test ah, 0x44; jp
-  0x6b097f` — the C2/C3 parity idiom in which `jp` (general path) fires
-  for `<`, `>`, AND unordered; the `fld [18f]; fdiv [4f]; ret` fall-through
-  executes only when C3=1/C2=0, i.e. skill == 800 exactly. The general
-  path decodes instruction-by-instruction to
-  `(LoadMod(load) * (skill/(skill+200)*11) + 4) / scaling / 4`
-  (constants 200f @0x00803b8c, 11f @0x00803b88, 4f @0x007c6174, /scaling
-  from `[esp+0xc]`, final /4f @0x00803b80). **ACE's `>= 800` "max run
-  speed?" reading is a misread of the same mush and must not be used as a
-  tiebreaker here** — it flat-lined every maxed character at 4.5 (retail
-  general formula gives ~3.70) and erased the vitae speed differential
-  (#266: 33%-vitae +Acdream visibly outran 5%-vitae +Je in acdream while
-  retail runs them within ~0.4%). `InqMaxRunRate`'s skill=9999 probe gets
-  the general formula (~3.6961), not 4.5. The true retail signature
-  carries a 3rd `scaling` arg (confirmed by the decomp's own function
-  signature), and every known call site (`InqMaxRunRate`, `InqRunRate`)
-  passes `1f`.
- `GetJumpHeight(load, skill, extent, scaling)` — BN's extent-clamp
-  micro-branch (pc 006b09b0-006b09ca) is the SAME x87-mush pattern as §3;
-  ACE's `Math.Clamp(extent, 0, 1)` is the tiebreaker (matches the EXISTING
-  acdream code, which already does this — unchanged).
-  `= LoadMod(load) * (skill/(skill+1300)*22.2 + 0.05) * clampedExtent / scaling`,
-  floored at 0.35 — matches acdream's pre-existing formula exactly.
- `JumpStaminaCost(power, load, pk)`:
-  - `pk==0`: `ceil((load + 0.5) * power * 8 + 2)` — **the campaign plan's
-    own shorthand ("ceil((power+0.5)*load*8+2)") has the `+0.5` term on the
-    wrong operand; the verbatim decomp (fully readable, no mush) is
-    `(load + 0.5) * power`, confirmed against ACE's identical
-    `(burden + 0.5f) * power`.**
-  - `pk!=0`: BN drops the body entirely (bare `_ftol2()` tailcall, no
-    operands survive); ACE's `(int)((power + 1.0f) * 100.0f)` is the
-    tiebreaker. Unused by P1 (`pk` is hardcoded `false` — see §4), ported
-    anyway for signature completeness/citation.
- `EncumbranceSystem::{EncumbranceCapacity, Load, LoadMod}` (0x004fcc00/40/70,
-  pc 256393+) — already verbatim-ported as `AcDream.Core.Items.BurdenMath`;
-  P1's `EncumbranceSystem` delegates (see §2).
-
-## 7. What "weak jump" actually is (no hard refusal exists)
-
-Given §4 (JumpStaminaCost never refuses) and §5 (stamina==0 zeroes the
-EFFECTIVE skill, not the extent), the retail zero-stamina jump is:
-`GetJumpHeight(load, skill=0, extent, 1) = LoadMod(load) * 0.05 * extent`,
-floored to the 0.35 m minimum by the function's own clamp — i.e. **every
-jump attempt, however exhausted, still produces at least the 0.35 m floor
-hop.** There is no code path in `CACQualities` that makes `jump_is_allowed`
-return `GeneralMovementFailure` due to low stamina. The campaign plan's
-"weak/refused jump" acceptance phrasing is satisfied by "weak" (the floor
-hop); "refused" does not occur via burden/stamina in this chain and P1 does
-not invent it.
-
-## 8. ReportExhaustion — wiring the dead R3-W4 seam
-
-`ReportExhaustion()` (`MotionInterpreter.cs:1619`, already a full verbatim
-port of `CMotionInterp::ReportExhaustion` 0x005288d0) has ZERO callers
-anywhere in the codebase today. Retail's caller chain is
-`CPhysicsObj::report_exhaustion` (0x0050fdd0) →
-`MovementManager::ReportExhaustion` (0x00524360), both outside
-`CMotionInterp`'s scope and not yet located precisely in the decomp
-(out of P1's bounded scope to hunt down the exact upstream trigger site).
-What we DO know precisely: its effect is "re-apply current movement through
-the SAME dual-dispatch predicate as `apply_current_movement`" — i.e. force a
-fresh `WeenieObj.InqRunRate`/`InqJumpVelocity` query against the CURRENT
-physics/interpreted state, with no new input event.
-
-That is exactly the primitive needed to make a live burden/stamina/vitae
-change visible immediately (mid-run, mid-charge) instead of waiting for the
-next keypress. **P1 wires `ReportExhaustion()` as the "re-evaluate movement
-now" trampoline any time Runtime pushes a fresh burden, stamina, or
-vitae-adjusted-skill value into the active `PlayerMovementController`** —
-plausible given `ReportExhaustion`'s documented purpose, and the least
-speculative real consumer available for a seam that otherwise never fires.
-
-## 9. Design: where each input is computed and pushed
-
-```
-Runtime (AcDream.Runtime, presentation-free):
-  RuntimeCharacterState
-    - Spellbook (existing)               -- vitae + skill enchantments live here
-    - MovementSkills: RuntimeMovementSkillState (existing, EXTENDED)
-        RunSkill / JumpSkill             -- now the ADJUSTED (EnchantSkill'd) values

-      ContainerContentsReplaced,Cleared} + LocalPlayer.AttributeChanged(Strength)
-      + Spellbook.EnchantmentsChanged
-      -> recompute burden (Strength + prop 0xE6 aug + prop 5 EncumbranceVal,
-         SAME shape as IndicatorBarController.UpdateBurden/InventoryController.RefreshBurden)
-         using effective/enchantment-adjusted Strength
-      -> character.Character.MovementSkills.UpdateBurden(ratio)
-    - NEW: character.Character.LocalPlayer.Changed(VitalKind.Stamina)
-      -> character.Character.MovementSkills.UpdateStamina(current)
-    - all three trigger points additionally invoke the new
-      LiveCharacterSessionBindings.OnMovementStatsUpdated callback
-
-  RuntimeMovementSkillProjection.ApplyTo(skills, controller)  (existing seam,
-  called at construction AND reactively from OnSkillsUpdated/OnMovementStatsUpdated)
-    - SetCharacterSkills(run, jump)  (existing)
-    - NEW: SetCharacterBurden(burden), SetCharacterStamina(stamina)
-
-App (LiveSessionRuntimeFactory) / Headless (HeadlessSessionHost):
-    - OnMovementStatsUpdated: App wires ApplyTo(...) + controller.Motion.ReportExhaustion()
-      (mirrors the existing OnSkillsUpdated body, which P1 ALSO extends with
-      the ReportExhaustion() call for consistency); Headless passes null,
-      matching its existing OnSkillsUpdated: null (headless bots don't need
-      live mid-session re-apply to a controller that may not exist yet).
-
-Core (AcDream.Core.Physics, presentation-free, pure):
-  EncumbranceSystem  -- EncumbranceCapacity/Load/LoadMod, delegates to BurdenMath
-  MovementSystem     -- GetRunRate/GetJumpHeight/JumpStaminaCost/GetJumpPower
-  PlayerWeenie (CACQualities-shaped)
-    _burden (float), _currentStamina (int?, null=unknown) -- pushed via
-      SetBurden/SetStamina (SetBurden already existed, wires the dead setter)
-    _runSkill/_jumpSkill (int)  -- pushed via SetSkills, ALREADY vitae/enchant-
-      adjusted by Runtime before it arrives here (PlayerWeenie itself stays
-      a pure formula consumer -- no Spellbook/enchantment dependency, keeping
-      it trivially testable)
-    CanJump(extent)          -> _burden < 2.0  (UN-8 polarity, §3)
-    JumpStaminaCost(extent, out cost)
-                              -> cost = MovementSystem.JumpStaminaCost(extent, _burden, pk:false);
-                                 return true;   (§4 -- always true, TS-23 owns pk)
-    InqRunRate(out rate)     -> effSkill = _currentStamina == 0 ? 0 : _runSkill;
-                                 rate = MovementSystem.GetRunRate(_burden, effSkill, 1f);
-    InqJumpVelocity(extent, out vz)
-                              -> effSkill = _currentStamina == 0 ? 0 : _jumpSkill;
-                                 vz = sqrt(MovementSystem.GetJumpHeight(_burden, effSkill, extent, 1f) * 19.6f);
-```
-
-`_currentStamina == null` (never set — matches every existing test /
-call site that doesn't call `SetStamina`) never zeroes the skill, preserving
-every pre-P1 `PlayerWeenieTests.cs` expectation unchanged.
-
-## 10. Register bookkeeping (same commit as the port)
-
- **Delete TS-5** (`CanJump` always true / `JumpStaminaCost` zero-cost stub) —
-  retired: both now real, decomp-cited.
- **Delete AP-25** (run/jump skill = attributeBonus+init+ranks only, no
-  vitae) — retired: vitae now flows through `EnchantmentMath.GetSkillMod`.
- **TS-21 untouched** — still valid (pre-PD fallback defaults 200/300 are a
-  separate divergence, not addressed by P1).
- **TS-23 extended** (not a new row) — its "PlayerKillerStatus not parsed"
-  scope now also covers the new `MovementSystem.JumpStaminaCost` `pk`
-  parameter, hardcoded `false` at the `PlayerWeenie` call site pending P3.
- **AP-127 retired 2026-07-31 (#268)** — the complete 0x16D/category/
-  0x146/0x158 chain is shared by panel and movement (§5 closeout).
- **New UN-8** — `CACQualities::CanJump`'s x87 comparison polarity resolved
-  by domain plausibility rather than a literal BN read (§3); Ghidra MCP
-  confirmation is the retire path.
-
-## 11. Test plan
-
- `MovementSystemTests` (new, Core): golden tables for `GetRunRate` (0/200/
-  800 skill, load knees), `GetJumpHeight` (extent 0/0.5/1, 0.35 floor,
-  load knees), `JumpStaminaCost` (ceil rounding, load/power sweep),
-  `GetJumpPower` (inverse sanity, not consumed by P1 but ported for
-  signature completeness / future charge-meter work).
- `EncumbranceSystemTests` (new, Core): capacity at 100%/200% aug clamp,
-  Load ratio, LoadMod knees — cross-checked 1:1 against the EXISTING
-  `BurdenMath` tests (same formulas, must agree bit-for-bit).
- `PlayerWeenieTests` (extend): CanJump refusal at load>=2.0 / allowed
-  below; JumpStaminaCost real nonzero cost; InqRunRate/InqJumpVelocity
-  zero at stamina==0 (skill forced to 0, still floors at 0.35 m for jump);
-  ALL pre-existing tests must stay green unmodified (no SetStamina call ->
-  null sentinel -> no gating, exactly today's behavior).
- `EnchantmentMathTests` (extend): `GetSkillMod` type-flag filtering

-
-i.e. PK/PKLite status AND a 20-second recency window on PropertyFloat

-# TS-4 / #116 oracle pass — Campaign P final physics slice
-
-**Status: RESEARCH ONLY. No source changes.** This is a follow-up oracle
-pass on top of `docs/research/2026-07-30-response-layer-edge-family-pseudocode.md`
-(hereafter "the P2 doc"), specifically its §4 (TS-4), §5 (#116), and §7
-item 6 (the P2 implementation attempt's wedge diagnosis). That attempt
-correctly localized the freeze to `TransitionalInsert`'s Phase 2 retry
-loop but concluded the mechanism was "Phase 3 structurally unreachable"
-without tracing far enough to find the actual convergence/divergence
-point. This pass reads one layer deeper — into `BSPQuery.cs`'s `Path 4`
-dispatch (the `path.Collide` gate) and `AdjustOffset`'s crease-projection
-math — and finds a concrete, retail-decomp-cited mechanism for both TS-4
-and (as a byproduct of reading the same dispatch structure) strong new
-evidence for #116 shapes 1 and 2.
-
-Every claim is tagged **FACT** (read directly from the named-retail
-pseudo-C, ACE source, or current acdream source in this worktree, with
-file:line / address citations) or **INFERENCE** (derived from those FACTs
-by direct reasoning, not yet confirmed by a live capture/cdb run).

-
-## 0. Binding DO-NOT-RETRY entries (copied verbatim)
-
-From `memory/project_physics_collision_digest.md` (3-day-old snapshot,
-re-verified against current source where cited below) and
-`docs/ISSUES.md` #116:
-
-1. **Do NOT add `SetSlidingNormal` calls in the BSP/sphere collision
-   layer.** Retail's only in-transition writer of
-   `collision_info.sliding_normal` is `validate_transition`
-   (`0x0050ac21`/`0x0050aa70`). A leaked normal + success writeback = an
-   absorbing wedge at empty space. **This pass's TS-4 finding is a
-   variant of exactly this failure class — see §1 below — but the
-   writer in question (`validate_transition`'s unconditional
-   `SetSlidingNormal(CollisionNormal)`) IS the retail-faithful one; the
-   problem is not an extra writer, it's what `AdjustOffset` does with a
-   *placeholder* `UnitZ` value when it reads `SlidingNormal` back.**
-2. **Do NOT re-add a forced constant-shell de-penetration.** Retail
-   slides tangentially and never force-separates.
-3. **`SphereCollision` no longer calls `SetSlidingNormal`** (TS-45
-   retired) — keep it that way.
-4. **Do NOT patch the degenerate-offset guard in `slide_sphere` ad
-   hoc** for #116 — oracle-driven only.
-5. **Do NOT re-introduce a topology-based outside-add / radial sweep**
-   to cell membership while touching this family.
-6. **`calc_friction` threshold is retail 0.25 vs acdream 0.0` (AP-7)** —
-   orthogonal to this slice, do not fold in.
-7. **Shape-1 of #116 is NOT the degenerate-offset guard threshold** —
-   that guard kills slides under ~1.4 cm; the lost tick-22760 slide was
-   3.57 cm. The divergence is the collision-normal SOURCE.
-8. **Do NOT guess the BN `test ah,5` x87 branch polarity/squaring** in
-   `slide_sphere` — Ghidra MCP is down for this pass too; this pass does
-   **not** touch that question (see §3, shape-2 — the finding here is
-   about dispatch *routing*, not the x87 comparisons inside
-   `slide_sphere`/`AdjustOffset` themselves, which remain unconfirmed
-   and out of scope).
-9. **AP-4 (CliffSlide check moved before retail's Branch-1 gate)** — a
-   live, load-bearing reordering. Not touched by this pass.
-10. **TS-46 (two-scalar sphere reconstruction) is OUT OF SCOPE.**

-
-## 1. TS-4 — the actual convergence/divergence mechanism
-
-### 1.1 Summary answer (read this first)
-
-**Retail does not "avoid" the Adjusted↔retry oscillation inside
-`transitional_insert`'s attempt loop any differently than acdream does —
-both structurally deadlock the same way within a single resolve.** What
-lets retail's *live* trace escape (and what the P2 fixture's synthetic
-trajectory does not) is that **retail's `AdjustOffset`
-(`CTransition::adjust_offset`, `0x0050a370`) re-projects the *next
-tick's* gravity offset through whatever `ContactPlane` +
-`SlidingNormal` survived the previous tick's collision — and for a
-pure, zero-horizontal-velocity vertical fall onto a steep surface, that
-projection is mathematically degenerate and crushes the offset to
-(near-)zero every tick, which abort-small-offsets before
-`TransitionalInsert` even runs again.** This is retail-faithful
-behavior, present identically in the raw decomp, in ACE's port, and in
-acdream's current port — it is not a bug introduced by the TS-4
-shortcut's removal. The `Ts4SteepRoofWedgeCaptureTests` fixture
-reproduces it because it drops the body **straight down with zero
-horizontal velocity**, which is very likely a different (and more
-degenerate) input than the live 2026-04-30 debugger trace that
-validated the shortcut (a player *jumping or running* onto a roof,
-which has residual horizontal velocity).
-
-### 1.2 The chain, FACT by FACT
-
-**Step A — Path 6 fires, sets `Collide`, does not reposition (FACT).**
-`BSPQuery.cs:2217-2224` (faithful branch, shortcut removed):
-```csharp
-path.SetCollide(worldNormal0);
-path.WalkableAllowance = PhysicsGlobals.LandingZ;
-return TransitionState.Adjusted;
-```
-`SpherePath.SetCollide` (`TransitionTypes.cs:752-759`) only sets
-`Collide=true`, backs up `CheckPos`, and stores `StepUpNormal` — it does
-**not** touch `CollisionInfo.ContactPlane` or `CollisionNormal`. Matches
-retail exactly: pseudo-C:323818-323821 (`0x0053a7bf`,
-`SPHEREPATH::set_collide(&sphere_path, &normal); walkable_allowance =
-0.0871556997f; return 3;`) — no `set_collision_normal`, no
-`set_contact_plane` call at this site either.
-
-**Step B — the SAME attempt's retry does NOT re-hit Path 6; it routes to
-Path 4 (FACT, both acdream and retail).** `BSPQuery.cs:1961` gates on
-`if (path.Collide)` — checked **before** the Path 5/6 tests, at the top
-of the same dispatch function. Since `Collide` was just set in Step A
-and is **never cleared** except inside `TransitionalInsert`'s Phase 3
-(`sp.Collide = false` at `TransitionTypes.cs:1816`, reachable only on an
-`OK` result — never reached while Path 6/Path 4 keep returning
-`Adjusted`), every subsequent attempt (within the same resolve **and**
-across ticks) dispatches to Path 4, not back to Path 6. Retail: raw
-pseudo-C:323784 `if (eax->sphere_path.collide == 0) {...} else {...}` —
-the identical gate, at the identical position in the dispatch (confirmed
-independently against ACE `BSPTree.cs:163-187`, `if (path.Collide) {
-RootNode.find_walkable(...); if (changed) {... return Adjusted;} else
-return OK; }`).
-
-**Step C — Path 4 (`FindWalkableInternal`) is what actually establishes
-`ContactPlaneValid` (FACT).** `BSPQuery.cs:1968-2018`: calls
-`FindWalkableInternal`; if it finds a candidate (`changed &&
-hitPoly is not null`), it **repositions** the sphere
-(`path.AddOffsetToCheckPos(worldOffset)`), sets a **real**
-`ContactPlane` via `collisions.SetContactPlane(worldPlane, ...)`
-(line 2006), caches the walkable polygon (`SetWalkableTransformed`), and
-returns `Adjusted`. This is the only site that gives the mover a real
-(steep) contact plane in this whole trajectory — **not** the Phase-3
-`DoCheckWalkable` gate the P2 doc's item-6 diagnosis assumed was the
-relevant site (that gate is downstream and, per Step B, unreachable
-here). Matches ACE `BSPTree.cs:163-184` exactly (`SetContactPlane`,
-`SetWalkable`, `return Adjusted`).
-
-**Step D — the attempt-exhausted `Adjusted` gets collapsed to `OK` with
-position reverted, but `ContactPlaneValid` survives the revert (FACT,
-both engines).** `TransitionalInsert`'s outer for-loop exhausts (acdream
-hardcodes `return TransitionState.Slid;` at `TransitionTypes.cs:2093`;
-ACE/retail return the true last value, `Adjusted` here — see §1.4 for why
-this particular divergence doesn't change the outcome). Either way,
-`ValidateTransition`'s "not OK" branch runs
-(`TransitionTypes.cs:5493-5501`): `if (!CollisionNormalValid)
-SetCollisionNormal(UnitZ);` (fires — Path 4/6 never touched
-`CollisionNormal`, only `ContactPlane`/`StepUpNormal`), then
-`SetCheckPos(CurPos, CurCellId)` (revert — no net movement),
-`transitionState = OK`. Retail: pseudo-C:272563-272596 (`0x0050aad9`),
-identical collapse (`COLLIDED_TS`/`ADJUSTED_TS`/`SLID_TS` all treated the
-same, default `CollisionNormal=UnitZ` if unset, revert `check_pos` to
-`curr_pos`). **Crucially, none of this touches `ContactPlaneValid`** — it
-carries forward from Step C untouched by the revert. Then the shared
-tail (`TransitionTypes.cs:5504-5533`, retail pc:272621-272656) runs:
-`if (CollisionNormalValid) SetSlidingNormal(CollisionNormal)` — now
-**`SlidingNormal = UnitZ`** (the placeholder from the default, not a
-real second surface) — and `if (ContactPlaneValid) { ...;
-oi.State|=Contact; if (Normal.Z>=FloorZ) OnWalkable=true else false; }`
-— since the steep polygon's `Normal.Z` (≈0.447 for the fixture's 63.4°
-slope) `< FloorZ` (≈0.664), `OnWalkable` stays **false** but `Contact`
-becomes **true**. **This exactly reproduces the fixture's own captured
-state at the landing tick: `InContact=true, OnWalkable=false`.**
-
-**Step E — the NEXT tick's `AdjustOffset` crushes a purely-vertical
-offset to zero (FACT for the math, INFERENCE that this is the actual
-observed freeze cause — not independently re-run this pass).**
-`TransitionTypes.cs:4936-5014` (acdream), `Transition.cs:34-87` (ACE),
-pseudo-C:272271-272393 (`0x0050a370`, retail) are all structurally
-identical:
-```
-slidingAngle = Dot(offset, SlidingNormal)
-if (SlidingNormalValid) { if (slidingAngle < 0) checkSlide = true; else SlidingNormalValid = false; }
-...
-if (checkSlide) {
-    slideOffset = Cross(ContactPlane.Normal, SlidingNormal)
-    normalize slideOffset (or zero out if degenerate)
-    result = Dot(slideOffset, offset) * slideOffset
-}
-```
-With `offset = (0, 0, -dz)` (pure gravity, zero horizontal component),
-`SlidingNormal = UnitZ = (0,0,1)`: `slidingAngle = -dz < 0` →
-`checkSlide = true`. `slideOffset = Cross(ContactPlane.Normal, UnitZ)` —
-for any non-vertical plane normal `N=(Nx,Ny,Nz)`, this cross product is
-`(Ny, -Nx, 0)` — a **horizontal** vector (Z=0), lying in the slope's
-*contour* line (perpendicular to the downhill direction), **not the
-degenerate/near-zero case** (the 63.4° slope's normal is not parallel to
-UnitZ, so `NormalizeCheckSmall` does not fire). `Dot(slideOffset,
-offset) = Dot((Ny,-Nx,0), (0,0,-dz)) = 0` exactly, because
-`slideOffset.Z = 0` and `offset` is purely `Z`. **`result = 0 *
-slideOffset = Vector3.Zero`.** The projected `GlobalOffset` is zero (up
-to float noise), which trips the "abort-small-offset" guard
-(`TransitionTypes.cs:1466-1478`, retail's non-viewer `|offset|² <
-F_EPSILON²` gate at pseudo-C:272845/`0x0050bdf0`, cited already in the
-existing `AdjustOffset` port comment) **before `TransitionalInsert` is
-even called again** — so `ValidateTransition` never runs on subsequent
-ticks either, meaning the stale `ContactPlaneValid`/`SlidingNormal=UnitZ`
-state simply perpetuates unchanged, forever. This is the freeze.
-
-**Step F — why the existing frames_stationary_fall (fsf) escape valve
-can't rescue this case (INFERENCE, follows directly from Step E).** The
-digest's #182 rebuild already ported retail's fsf ladder
-(`TransitionTypes.cs:5625-5667`, ACE `Transition.cs:1029-1061`,
-pseudo-C:272625-656) — after 3 consecutive non-advancing ticks it
-manufactures a flat `UnitZ` contact plane and forces `OnWalkable=true`,
-which is exactly the kind of "unstick" mechanism one would look for
-here. **But that ladder lives inside `ValidateTransition`, which Step
-E's abort-small-offset guard prevents from ever running again** once the
-crease projection first crushes the offset to zero. The rescue mechanism
-is downstream of a gate the degenerate input never lets execution
-reach — in both acdream and (per identical source) retail.
-
-### 1.3 Why this reconciles the shortcut's own "retail did not wedge" comment (INFERENCE)
-
-The shortcut's comment (`BSPQuery.cs:2190-2199`) says the interim fix was
-"Validated against retail debugger trace 2026-04-30: retail body did not
-wedge." A live player jumping or walking onto a roof virtually always
-carries **some** horizontal velocity component (WASD input, residual
-momentum). For a non-purely-vertical `offset`, `Dot(slideOffset, offset)`
-is generally **non-zero** (only a component exactly along the pure
-downhill/gravity line is annihilated by this specific cross product —
-any lateral drift survives), so `AdjustOffset` would produce a small but
-non-zero *sideways* offset each tick — enough to move the sphere off the
-exact same collision point, avoid the abort-small-offset short-circuit,
-let `TransitionalInsert`/`ValidateTransition` run again, and (via
-repeated Path-4 `find_walkable` re-probes and the fsf ladder) eventually
-resolve. **The `Ts4SteepRoofWedgeCaptureTests` fixture's `pos =
-(0.5, 0, 3.0)` straight-down drop with `fallVelocityZ` as the only
-non-zero component is very likely a stricter, more degenerate input than
-the live 2026-04-30 repro ever exercised.** This is not yet independently
-re-confirmed by re-running the fixture with a horizontal component (see
-§4 Step 1 below for the concrete next action), so it is flagged
-INFERENCE — but it is the only hypothesis consistent with every FACT
-gathered in §1.2, and it does not require inventing any new mechanism.
-
-### 1.4 The acdream-only bug that does NOT explain the freeze, but is real and should still be fixed
-
-`TransitionTypes.cs:2091-2093`:
-```csharp
-// Exhausted retry attempts — return whatever the last iteration said.
-// (Defaults to Slid in practice since that's the only case that retries.)
-return TransitionState.Slid;
-```
-This is **hardcoded**, not "whatever the last iteration said" as the
-comment claims. ACE's equivalent (`Transition.cs:933`, `return
-transitState;`) and retail's (pseudo-C:273363, `0x0050b949`, `return
-edi;`) both return the **true** last value — `Adjusted` in this
-scenario, not `Slid`. **FACT: this is a real, citable divergence.**
-**FACT: it does not explain the freeze** — `ValidateTransition`'s
-"not OK" branch (§1.2 Step D) treats `Collided`/`Adjusted`/`Slid`
-**identically** (acdream `TransitionTypes.cs:5493-5501`, ACE
-`Transition.cs:993-1017`, retail pseudo-C:272563-272596 all gate on
-`result > OK_TS && result <= SLID_TS` as one combined range, with no
-per-value branching). Fixing the hardcoded return is a one-line,
-zero-risk correctness fix (worth doing — it's a real citable
-port-accuracy bug and prevents future confusion when tracing this loop)
-but it is **not** the TS-4 fix and should not be presented as one.
-
-### 1.5 What TS-4's actual fix shape is, given this
-
-The mechanism in §1.2 is **not something `BSPQuery.cs`'s Path 6 can fix
-by itself** — the freeze happens one tick *after* Path 6/Path 4 run,
-inside `AdjustOffset`, and is a property of the (already retail-faithful)
-`validate_transition` + `adjust_offset` pipeline reacting to a specific
-degenerate trajectory. Concretely, TS-4's shortcut removal is very
-likely **safe for the realistic case** (nonzero horizontal velocity) and
-only exposes this specific zero-horizontal-velocity degenerate, which:
- may be a genuine, narrow, retail-faithful edge case (a player falling
-  perfectly plumb onto a slope with zero horizontal drift essentially
-  never happens in live play — WASD input, camera-relative movement, and
-  even tiny numerical noise almost always inject some horizontal
-  component), in which case it is not a blocker for TS-4 at all and
-  should be documented as an accepted (retail-matching) corner case
-  rather than "fixed", **or**
- may indicate the fixture itself should be revised to match the
-  original live repro's actual trajectory shape (nonzero horizontal
-  velocity) before it's trusted as TS-4's gating fixture.
-
-See §4 for the concrete, low-cost verification step (re-run the fixture
-with a small horizontal velocity component) that would settle which of
-these is true without guessing.

-
-## 2. #116 shape-1 — collision-normal recording divergence (new candidate, INFERENCE, needs one instrumentation run to confirm)
-
-### 2.1 What the existing research already ruled out (FACT, restated)
-
-Ghidra-confirmed (2026-06-12, digest lines 1268-1275): acdream's
-`cn=UnitZ` default on a blocked move **is** retail-faithful
-(`validate_transition` does the identical default). The real divergence
-is **upstream** — at tick-22760, acdream's `collision_normal_valid` was
-`false` where retail's was `true` (retail had recorded the door-face
-normal `(0,+1,0)`). The candidate site named in the P2 doc §5 was "the
-`PathClipped`/`collide_with_pt` arm... or a sibling Path-1-class function
-not yet read."
-
-### 2.2 PathClipped is NOT the answer (checked this pass, negative result — FACT)
-
-`ObjectInfoState.PathClipped` (`TransitionTypes.cs:32`, bit `0x8`) is
-only set on a mover when `MoverPhysicsState & PhysicsStateFlags.Missile
-!= 0` (`PhysicsEngine.cs:1160-1163`), with an explicit citation to
-retail's own `CPhysicsObj::get_object_info` (`0x00511CC0`): "Missile
-contributes PathClipped only." A normal player push against a door is
-not a missile mover, so **neither acdream nor retail would set
-PathClipped for this scenario** — this rules out "PathClipped state
-differs between engines" as shape-1's cause. (The camera/viewer sweep
-does carry PathClipped via a different, explicit caller-supplied flag,
-but that's a different mover than the one in the tick-22760 door-push
-capture.)
-
-### 2.3 The real candidate: acdream's Path-6 sphere1(head)-hit handling diverges from retail/ACE (FACT for the divergence, INFERENCE that it explains tick-22760)
-
-Retail's `BSPTREE::find_collisions`, in the **not-yet-in-Contact**
-branch (`state&1==0`, i.e. airborne / first contact — pseudo-C:323784-
-323836, `0x0053a4e3`-`0x0053a730`+): when sphere0 (foot) does **not**
-hit but `num_sphere > 1` and sphere1 (head) **does** hit, retail does
-**not** defer through `SetCollide`/`Adjusted` — it calls
-`COLLISIONINFO::set_collision_normal` **directly** with the head poly's
-transformed normal and returns `COLLIDED_TS` (`2`) immediately
-(pseudo-C:323824-323834, `0x0053a793`/`0x0053a7a4`). Cross-checked
-independently against ACE `BSPTree.cs:221-230`:
-```csharp
-else if (path.NumSphere > 1)
-{
-    if (RootNode.sphere_intersects_poly(localSphere_, movement, ref hitPoly, ref contactPoint) || hitPoly != null)
-    {
-        var collisionNormal = path.LocalSpacePos.LocalToGlobalVec(hitPoly.Plane.Normal);
-        collisions.SetCollisionNormal(collisionNormal);
-        return TransitionState.Collided;
-    }
-}
-```
-— an exact structural match to the raw decomp, confirming this is not a
-BN misdecompile.
-
-**acdream's corresponding code (`BSPQuery.cs:2227-2264`) does NOT do
-this.** It applies the *same* SetCollide-and-defer (or steep→`Slid`)
-treatment to a sphere1 hit as it does to sphere0 — there is no branch
-that returns `Collided` with a direct `SetCollisionNormal` write for "foot
-clear, head hit" while airborne. This means: **in acdream, an airborne
-mover whose HEAD sphere alone contacts a polygon (foot sphere clear) gets
-`SetCollide` + deferred `Adjusted` (no immediate `CollisionNormal`
-write) — exactly the same "the real normal gets lost until
-`validate_transition`'s `UnitZ` default kicks in" symptom the digest
-already diagnosed for shape-1.** A door push where the player's capsule
-brushes the door frame near chest/head height while the foot sphere
-tracks slightly differently (a very plausible geometry for "pushing a
-closed door face at a near-perpendicular angle," matching the tick-22760
-description) is a strong candidate for exactly this code path.
-
-**Caveat, stated honestly:** this is contingent on sphere0 (foot) *not*
-fully hitting while sphere1 (head) *does* — if the door's collision
-geometry is a full vertical plane, sphere0 would very likely hit too,
-and the code would never reach the sphere1 branch (`BSPQuery.cs:2156`'s
-`if (hit0 || hitPoly0 is not null)` returns early). This has **not**
-been confirmed against the actual tick-22760 replay this pass — it is
-the single next concrete step (see §4).
-
-### 2.4 Instrumentation to run (concrete, low-cost, no guessing required)
-
-Extend `DoorBugTrajectoryReplayTests.Diagnostic_Tick22760_DumpEngineInternals`
-(`tests/AcDream.Core.Tests/Physics/DoorBugTrajectoryReplayTests.cs:162`)
-to log, at the tick-22760 resolve, which of `hit0`/`hitPoly0`/`hit1`/
-`hitPoly1` were non-null/true inside `BSPQuery.cs`'s Path-6 dispatch
-(a one-line `Console.WriteLine` gated behind the existing
-`ProbeIndoorBspEnabled`/`ProbeBuildingEnabled` diagnostics, or a new
-narrowly-scoped probe flag per the project's diagnostic-owner pattern).
-
-**Accept criterion:** if `hit0`/`hitPoly0` are both null/false **and**
-`hit1`/`hitPoly1` fire, §2.3's hypothesis is confirmed — the fix is to
-port retail's direct sphere1-hit-without-sphere0-hit → `Collided` +
-`SetCollisionNormal` branch into `BSPQuery.cs`'s Path 6 (mirroring the
-already-correct Path 5/Contact-branch treatment at
-`BSPQuery.cs:2103-2140`, which already handles the analogous grounded
-case correctly — this would be a narrow, well-precedented port, not a
-new design).
-
-**Reject criterion:** if sphere0 hits too (`hit0` or `hitPoly0` truthy),
-this hypothesis is wrong for tick-22760 specifically, and the search
-should move to the *other* named-retail sibling not yet read this pass —
-`BSPTREE::collide_with_pt`'s own internal structure for a **non-PathClipped**
-context is not reachable (its outer gate requires `state&8`), so the
-next candidate would be whatever governs `CObjCell::find_obj_collisions`'s
-insertion order relative to `find_env_collisions` for a door's *building*
-channel (the BR-7/A6.P4 per-cell shadow architecture) — not yet examined
-this pass; would need a fresh read of that dispatch specifically for
-polygon ordering/precedence when multiple candidate polys are tested per
-cell.

-
-## 3. #116 shape-2 — first-airborne-frame hard-stop vs in-frame slide (strong structural finding, INFERENCE, narrows but does not eliminate the need for a confirming run)
-
-### 3.1 The dispatch structure resolves the ROUTING question without cdb (FACT, cross-referenced against 3 sources: raw BN pseudo-C, ACE, current acdream)
-
-Both the raw retail decomp and ACE's `BSPTree.cs` (an independent,
-clean-language port — the "fastest oracle" the mission suggested)
-show the **same two-tier gate**, keyed on `ObjectInfoState.Contact`:
-
- **Already grounded (`Contact` set) + head-sphere hit** → `slide_sphere`
-  called **directly, in-line, same tick** (ACE `BSPTree.cs:192-202`;
-  retail pseudo-C region immediately following `0x0053a730`'s `state&1`
-  branch — the `else` arm at ~323838+, not fully re-quoted here but
-  structurally mirrored by ACE's clean port). acdream's `BSPQuery.cs`
-  Path 5 (`:2103-2120`) already matches this exactly — `SlideSphere`
-  called directly for a grounded head-hit.
- **NOT yet grounded (`Contact` unset, i.e. airborne / first contact) +
-  foot-sphere hit** → the **Path-6 default**: `SetCollide` +
-  `WalkableAllowance=LandingZ` + return `Adjusted` — **no
-  repositioning, no `slide_sphere` call at all** (ACE `BSPTree.cs:210-219`;
-  retail pseudo-C:323815-323821). Only a sphere1(head)-hit-without-
-  sphere0-hit gets an immediate response in this branch, and that
-  response is `Collided` (§2.3), **still not `slide_sphere`**.
-
-**This means: for a genuine first-airborne-frame FOOT-sphere wall hit
-(the D4 fixture's actual shape — a mover falling into a tall wall),
-neither retail nor ACE's port calls `slide_sphere` on contact frame 1.**
-The sphere is left exactly where it was (`SetCollide` does not
-reposition — confirmed in §1.2 Step A), `Collide` gets set, and the
-**very next retry attempt** (same tick, same `TransitionalInsert` loop,
-per §1.2 Step B) routes to **Path 4** (`find_walkable`) instead. For a
-**tall, vertical wall** (D4's actual geometry — "TallWall" per the test
-name), `find_walkable`'s nearby-walkable-surface search would very
-plausibly find **no** candidate (a sheer vertical face has no
-near-horizontal polygon to "land" on nearby) — `changed=false` — so
-Path 4 returns `OK` (ACE `BSPTree.cs:185-186`, `else return
-TransitionState.OK;`). `TransitionalInsert`'s Phase 3 (`if
-(sp.Collide)`, now finally reachable since `objState==OK`) then runs:
-`ContactPlaneValid` is **false** (Path 4's `changed=false` arm never
-sets it), so the `else reset=true;` branch fires
-(`TransitionTypes.cs:1842-1843`), `RestoreCheckPos()` reverts to the
-pre-hit position, and the retail-faithful gate at
-`TransitionTypes.cs:1863-1898` (matching pseudo-C:273231-273239 exactly,
-already cited in-code) fires: since this is the *first* airborne
-contact, `LastKnownContactPlaneValid` is false, so
-`SetCollisionNormal(sp.StepUpNormal)` (the wall's **real** normal,
-captured back at the original Path-6 hit) runs and the function returns
-**`Collided`** — a **hard stop, in place, with the correct wall normal
-recorded** — not a slide.
-
-### 3.2 What this means for D4
-
-**INFERENCE, well-supported but not independently re-run this pass:**
-the D4 pin's original expectation (frame 1 hard-stops at Z=2.0, the
-slide begins frame 2 off the cached sliding normal) is structurally much
-closer to what retail's own dispatch produces for a true vertical-wall
-first-contact than the engine's current in-frame slide-to-Z=1.92
-behavior. **This narrows — but does not eliminate — the open question.**
-What remains genuinely unconfirmed by static reading (and is exactly
-the class of question DO-NOT-RETRY item 8 warns against guessing):
-
- Whether `find_walkable`'s internal walkable-search radius/height
-  actually returns "nothing found" for the *specific* D4 fixture
-  geometry (a wall tall enough that no nearby floor exists within its
-  search envelope) — this is a **testable, non-cdb** question: instrument
-  or step through `FindWalkableInternal` for the D4 geometry and confirm
-  `changed=false`.
- The exact x87 comparison polarities *inside* `slide_sphere` and
-  `find_walkable` themselves (unrelated to this pass's routing finding)
-  remain unconfirmed per DO-NOT-RETRY item 8 — but those don't matter for
-  D4 if `slide_sphere` is never reached on frame 1 in the first place.
-
-### 3.3 Recommended next step for shape-2 (no cdb needed for the routing question; cdb only if the confirming run disagrees)
-
-1. **First (cheap, no cdb):** run/instrument the existing
-   `BSPStepUpTests.D4_AirborneMover_TallWall_PersistsSlidingNormalAcrossFrames`
-   fixture (currently `Skip`-tagged citing #116) with a probe on which
-   `BSPQuery.cs` path fires on frame 1 (Path 6 vs Path 4 vs a full-hit-
-   the-second-attempt path) and whether `FindWalkableInternal` returns
-   `changed=true` or `false` for that specific wall. **Accept:** if
-   Path 6 fires (`SetCollide`+`Adjusted`, no reposition), Path 4 then
-   fires with `changed=false`, and the final result is `Collided` with
-   `StepUpNormal` as the recorded normal — this confirms §3.1/§3.2, and
-   the fix is to **flip the D4 pin back to hard-stop** (retire the
-   `Skip`, assert Z=2.0 frame 1) rather than changing the engine.
-   **Reject:** if the trace shows something else (e.g. Path 4 actually
-   finds a walkable candidate for this wall, or a different dispatch arm
-   fires entirely) — then the routing hypothesis in §3.1 doesn't hold for
-   this specific fixture geometry, and a live cdb trace becomes necessary
-   after all.
-2. **Only if step 1 disagrees with the FACT-cited dispatch structure:**
-   a live cdb trace of an actual airborne wall hit in retail, per the
-   CLAUDE.md "Retail debugger toolchain" section. Concrete script
-   outline (adapting the documented pattern):
-   ```
-   .logopen ts4-116-airborne-wallhit.log
-   .sympath C:\Users\erikn\source\repos\acdream\refs
-   .symopt+ 0x40
-   .reload /f acclient.exe
-
-   r $t0 = 0
-   bp acclient!BSPTREE::find_collisions "r $t0 = @$t0 + 1; .if (@$t0 % 1 == 0) { .printf \"hit %d: state=%%d collide=%%d\\n\", @$t0 } gc"
-   bp acclient!CSphere::slide_sphere "r $t1 = @$t1 + 1; .printf \"SLIDE_SPHERE HIT #%d\\n\", @$t1; .if (@$t1 >= 3) { qd } .else { gc }"
-   bp acclient!BSPTREE::collide_with_pt "r $t2 = @$t2 + 1; .printf \"COLLIDE_WITH_PT HIT #%d\\n\", @$t2; gc"
-   g
-   ```
-   User reproduces: jump toward a tall vertical wall so the FIRST wall
-   contact happens while airborne (not already grounded). The key
-   signal is whether `slide_sphere` fires on the **same** engine tick
-   as the first `find_collisions` hit against that wall (in-frame slide,
-   confirming the CURRENT engine behavior) or only on a **later** tick
-   (confirming the hard-stop-then-slide-frame-2 pin). Auto-detaches via
-   `qd` after 3 `slide_sphere` hits to bound game lag.

-
-## 4. Recommended execution order + blast radius
-
-1. **[Lowest risk, do first] Fix the `TransitionalInsert` exhausted-loop
-   hardcoded return** (§1.4): change `return TransitionState.Slid;` to
-   return the real last `transitState` value, matching ACE/retail. Blast
-   radius: essentially zero — `ValidateTransition` treats
-   `Collided`/`Adjusted`/`Slid` identically downstream (confirmed §1.2
-   Step D), so this is a pure code-correctness fix with no observable
-   behavior change in any currently-passing test. Good precursor because
-   it removes a misleading comment/return before anyone traces this loop
-   again.
-
-2. **[Cheap, decides whether TS-4 needs anything further] Re-run
-   `Ts4SteepRoofWedgeCaptureTests` with a small horizontal velocity
-   component** (e.g. `vx = 0.3` m/s alongside the existing straight-down
-   fall), shortcut removed. Per §1.3's hypothesis, this should **not**
-   wedge (the crease projection produces a non-zero tangential offset).
-   **Accept (doesn't wedge):** TS-4's shortcut removal is safe for the
-   realistic case; land it, retire the TS-4 register row, and either (a)
-   accept the pure-vertical case as a documented, retail-faithful corner
-   case (cite §1.2/§1.3 in the register row) or (b) if the team wants
-   zero residual risk, also file a narrow follow-up for the
-   zero-horizontal-velocity degenerate specifically (not a TS-4 blocker).
-   **Reject (still wedges even with horizontal velocity):** §1.3's
-   hypothesis is wrong or incomplete; do NOT land TS-4 yet — re-open with
-   a fresh capture of the actual velocity vector at the wedge point and
-   compare against what `AdjustOffset` computes step by step (a
-   `ACDREAM_DUMP_EDGE_SLIDE`-style trace of `AdjustOffset`'s intermediate
-   `slidingAngle`/`collisionAngle`/`slideOffset` values, not yet
-   instrumented, would be the concrete next apparatus).
-
-3. **[Independent of 1-2] #116 shape-1 instrumentation** (§2.4): add the
-   one-line hit0/hitPoly0/hit1/hitPoly1 probe to
-   `Diagnostic_Tick22760_DumpEngineInternals` and re-run. Blast radius:
-   zero (diagnostic-only). If confirmed, the fix (porting retail's direct
-   sphere1-hit → `Collided`+`SetCollisionNormal` branch into Path 6) is a
-   narrow, well-precedented addition mirroring the already-correct Path 5
-   treatment — moderate blast radius (touches the shared Path-6 dispatch
-   used by every airborne two-sphere mover), needs the existing
-   `SphereCollisionFamilyTests`/`Issue137*` suites re-run plus a fresh
-   tick-22760 comparison before landing.
-
-4. **[Independent of 1-3] #116 shape-2 instrumentation** (§3.3 step 1):
-   add the BSPQuery-path + `FindWalkableInternal` `changed` probe to the
-   D4 fixture. Blast radius: zero (diagnostic-only) for the instrumentation
-   itself. If confirmed, flipping the D4 pin (un-skip, assert hard-stop
-   frame 1) is a **test-only** change with **zero production code
-   change** — the engine's current dispatch already produces this
-   result per §3.1's reading; only the test's own expectation is
-   currently wrong. This is the lowest-risk of all four items once
-   confirmed, because it requires touching zero engine code.
-
-**Suggested order given the above:** 1 → 4 → 3 → 2, since 4 (#116
-shape-2) is the cheapest to fully resolve (test-only fix, zero engine
-change, per this pass's structural finding) and 2 (TS-4's own
-confirming run) benefits from having item 1's return-value fix landed
-first (removes a confusing false signal before re-tracing).
-
---
-
-## 5. What genuinely still needs cdb or Ghidra (not resolved by this pass)
-
-1. **#116 shape-2, only if §3.3 step 1's confirming run disagrees with
-   the FACT-cited dispatch structure.** The routing question itself
-   (does frame 1 reach `slide_sphere`) is resolved by static reading
-   against 3 independent sources in this pass; only a surprising,
-   contradicting instrumentation result would re-open the need for a
-   live trace. The cdb script outline is in §3.3 step 2.
-2. **The x87 comparison polarities inside `slide_sphere`,
-   `find_walkable`, and `AdjustOffset`'s own internal branches**
-   (DO-NOT-RETRY item 8) — untouched by this pass, remain Ghidra/cdb-
-   gated as before. This pass's findings are about which *function*
-   gets called (dispatch routing), not the exact comparison operators
-   inside those functions.
-3. **AP-7's `cos(10°)` vs `0.99999536f` discrepancy** (P2 doc §1) —
-   unrelated to this pass, still needs a Ghidra decompile of
-   `0050ee70` when Ghidra MCP is back up.
-4. **TS-1 gaps #2/#3's `last_known_contact_plane` maintenance and
-   Path-4 `LandingZ` acceptance audit** (P2 doc §2, §6 Step 2) — per the
-   current source read in this pass, this already carries an in-code
-   citation ("TS-1 gap #3 (register AD-54, Campaign P Slice P2
-   2026-07-30)") suggesting it was addressed in the same implementation
-   session that produced the P2 doc's item-6 update; not independently
-   re-verified this pass.
-
---
-
-## 6. One-paragraph summary for the calling agent
-
-**TS-4:** the Adjusted↔retry loop the P2 doc's implementation attempt
-found is real, but its root cause is one layer downstream of where that
-attempt looked. `Path 6` sets `Collide=true` without moving the sphere;
-every subsequent attempt (same tick and later ticks, since `Collide` is
-never cleared outside Phase 3) routes to `Path 4`
-(`FindWalkableInternal`), which is what actually establishes the steep
-`ContactPlane` (matching the fixture's observed `InContact=true,
-OnWalkable=false`). The freeze itself happens one tick later, inside
-`AdjustOffset`: `validate_transition`'s retail-faithful `CollisionNormal
-→ UnitZ` default feeds `SetSlidingNormal`, and `AdjustOffset`'s
-crease-projection (`Cross(ContactPlane.Normal, SlidingNormal)`) is
-mathematically orthogonal to a **purely vertical** input offset — every
-subsequent tick's gravity-only offset gets crushed to zero and
-abort-small-offsets before the engine can run again. This exact
-mechanism is present identically in the raw retail decomp, ACE's port,
-and acdream's current port — it is very likely not a code bug but a
-narrow degenerate case that a live player's residual horizontal velocity
-(present in the original validating debugger trace) would not trigger.
-The concrete next step is cheap and decisive: re-run
-`Ts4SteepRoofWedgeCaptureTests` with a small horizontal velocity
-component before deciding whether TS-4's shortcut removal needs anything
-beyond the register-row writeup.
-
-## Addendum (P-review byte decode, 2026-07-30): AD-55 RESOLVED — retail's sled flatness test is cos(10°), ACE's constant is a radians/degrees bug
-
-Raw bytes of `CPhysicsObj::calc_friction @ 0x0050ee70` (PDB-paired binary,
-technique `reference_pe_byte_decode`), Sledding fast-sled branch at
-0x0050ef52-0x0050ef6a:
-
-```
-d9 86 38 01 00 00   fld  dword [esi+0x138]    ; contact_plane.Normal.Z
-dd 05 28 6b 7c 00   fld  qword [0x007c6b28]   ; = 0.17453292519943295 (10 deg in RADIANS)
-d9 ff               fcos                       ; st0 = cos(10 deg) = 0.984807753
-de d9               fcompp
-df e0 / f6 c4 41 / 7a  fnstsw; test ah,0x41; jp
-```
-
-FACT: retail genuinely computes `cos(10°) ≈ 0.9848078` at runtime and
-compares `Normal.Z` against it. ACE's `0.99999536f` equals
-`cos(0.1745 DEGREES)` — the radian literal evaluated in degree mode; a
-proven ACE porting error, not a BN artifact. Sibling constants
-byte-confirmed: threshold float 0.25 @0x007c6b00, doubles 6.25/1.5625
-@0x007c6b30/38, friction overrides 1.0f/0.2f as immediates.
-
-Feel impact: retail's 0.2-friction fast-sled override engages on ground
-within 10° of flat; the shipped ACE-derived constant engages only within
-0.17° (never, in practice) — part of the #166 sled family. FIX (queue for
-the TS-4/#116 implementation slice, which owns `PhysicsBody`): replace
-`0.99999536f` with `0.98480775f` (cos 10°), cite this addendum, retire
-register row AD-55 in the same commit.
-
-## Addendum 2 (implementation session, 2026-07-30): #116 shape-1's tick-22760
-## confirming run DISAGREES with this plan's hypothesis — the real mechanism
-## is one layer further upstream, and it's retail-faithful there too
-
-Per this doc's own §4 execution order, item 1 (the `TransitionalInsert`
-exhausted-loop hardcoded return) landed first — mechanical, zero
-observable behavior change, confirmed by the full `AcDream.Core.Tests`
-suite (4059 passed / 2 skipped, no change in pass count). Then §2.3's
-shape-1 fix landed verbatim in `BSPQuery.cs`'s Path 6 `hasSphere1`
-branch: a foot-clear/head-hit airborne contact now returns
-`TransitionState.Collided` with a direct `collisions.SetCollisionNormal`
-write, exactly matching pc:323824-323834 (`0x0053a793`/`0x0053a7a4`) and
-ACE `BSPTree.cs:221-230`. This is a real, independently-decomp-confirmed
-port-accuracy fix and is kept regardless of the result below.
-
-**The confirming instrumentation run (§2.4) DISAGREES with the plan's
-tick-22760 hypothesis.** Re-running
-`DoorBugTrajectoryReplayTests.Diagnostic_Tick22760_DumpEngineInternals`
-after the fix landed shows **no change**: harness still reports
-`cn=(0,0,1)` (the `UnitZ` ground-fallback default) against live's
-`cn=(0,+1,0)` (the door-face normal). Adding a dispatcher-entry probe
-(`[path-dispatch]`, `[path5-diag]`, gated on the existing
-`ProbeIndoorBspEnabled` flag, kept in `BSPQuery.cs` as permanent
-diagnostics) traced the ACTUAL call sequence for this capture:
-
-1. The seeded body's `TransientState` (131 = `Contact | OnWalkable |
-   Active`) means `ObjectInfo.State & Contact != 0` for this mover — it
-   is **grounded**, so `BSPQuery.FindCollisionsCore` dispatches to
-   **Path 5** (the Contact/grounded branch), never Path 6 at all. The
-   plan's shape-1 hypothesis was explicitly scoped to "the not-yet-in-
-   Contact branch" (§2.3) — that scoping was itself the unconfirmed
-   part, and it does not hold for tick-22760.
-2. Path 5's own dispatch for the door's BSP shape at this exact position
-   finds **neither sphere hitting nor near-missing**
-   (`hit0=False hitPoly0=False hit1=False hitPoly1=False`) — the
-   simplified fixture registration this test uses
-   (`BuildEngineWithDoorFixture`, which places the raw GfxObj BSP
-   directly at its captured world-space bounding-sphere center rather
-   than via the faithful `ShadowShapeBuilder.FromSetup` +
-   `PlacementFrame` transform that `BuildFaithfulDoorEngine` uses
-   elsewhere in the same file) returns `OK` for the door here.
-3. `TransitionalInsert`'s step-down gate then fires
-   (`contactInvalidOrSteep` is true because the per-substep walk loop
-   clears `ContactPlaneValid` before every `TransitionalInsert` call —
-   `TransitionTypes.cs` around the `FindValidPosition` per-step reset —
-   so the door BSP is queried TWICE MORE via `DoStepDown`'s two half-
-   height attempts, dispatching to **Path 3** (`StepSphereDown` →
-   `FindWalkableInternal`), which also finds no walkable candidate here
-   (the door face is not a floor-like polygon) and returns `OK` both
-   times.
-4. Both `DoStepDown` calls therefore fail (return `false`), which routs
-   into `EdgeSlideAfterStepDownFailed`. With `ContactPlaneValid` false,
-   `OnWalkable` true (seeded), `EdgeSlide` true (mover flags), and the
-   RESTORED walkable polygon from the body's own snapshot (a flat
-   triangle `(144,0,94)-(144,24,94)-(120,24,94)`, `Normal.Z=1 >=
-   FloorZ`), execution reaches `sp.PrecipiceSlide(this)`
-   (`TransitionTypes.cs` "branch3/precipice-slide").
-5. **`SpherePath.PrecipiceSlide` calls `BSPQuery.FindCrossedEdge` against
-   that seeded triangle. The player's actual sweep (X≈133, Y from 18.02
-   to 17.60) does not cross ANY of that triangle's three edges** (the
-   triangle spans roughly X∈[120,144], and its hypotenuse sits at
-   X+Y=144 — at X=133 that's Y≈11, far south of the player's Y range).
-   `FindCrossedEdge` returns false, and acdream's `PrecipiceSlide`
-   (`TransitionTypes.cs:1039-1054`) does exactly what retail's
-   `SPHEREPATH::precipice_slide` does on the identical branch — **read
-   fresh this session, pc:274316-274326, `0x0050cc80`**:
-   ```
-   int32_t eax = CPolygon::find_crossed_edge(...);
-   if (eax == 0) { this->walkable = eax; return 2; /* COLLIDED_TS */ }
-   ```
-   **No `set_collision_normal` call on this path in retail either.**
-   This is a byte-exact match, not an inference — acdream's
-   `ClearWalkable(); return TransitionState.Collided;` on a failed
-   `FindCrossedEdge` is retail-faithful. `ValidateTransition`'s
-   `UnitZ`-default-on-invalid-normal fires identically in both engines
-   for this exact mechanism.
-
-**Conclusion: the tick-22760 divergence is NOT explained by anything this
-plan identified, and the mechanism this pass traced down to (Path 5 →
-StepSphereDown → EdgeSlideAfterStepDownFailed → PrecipiceSlide's
-no-crossed-edge fallback) is independently confirmed retail-faithful at
-every step, including a fresh byte-level read of `precipice_slide`
-itself.** The remaining candidates, none guessed at here: (a) this
-specific harness (`BuildEngineWithDoorFixture`) may simply not place the
-door's BSP polygons where live retail's did at that exact tick — a
-harness/fixture-geometry gap, not a response-layer code bug — worth
-re-running this same capture through `BuildFaithfulDoorEngine`'s
-Setup-based registration to check whether a REAL BSP hit against the
-door (rather than the seeded generic floor triangle) changes the
-outcome; (b) the seeded `WalkableVertices` triangle itself may not match
-what retail's own walkable-polygon bookkeeping held at that instant
-(a state-capture gap in the original 2026-05-24 live-capture tooling,
-not necessarily an engine bug); (c) a genuinely different upstream
-mechanism not yet traced. Per CLAUDE.md's no-guessing rule, none of
-these is adopted without further evidence — #116 shape-1 stays
-**narrowed, not closed**: the Path-6 fix is a real, independent
-retail-faithfulness improvement, and the original tick-22760 acceptance
-criterion is NOT met by it. See ISSUES.md #116 for the updated status.

-# Issue #269 — slope-stop capture and retail correction
-
-**Date:** 2026-07-31
-**Status:** implemented; user live gate passed
-**Scope:** landing-bounce follow-up, `CTransition::validate_transition`
-
-## Symptom
-
-After the retail 5%-elasticity landing reflection was restored for #265,
-the character could retain too much downhill speed after landing on a
-walkable slope. The user described the residual as “slides too far on
-landing.”
-
-## ACDream live capture
-
-`ACDREAM_CAPTURE_PLAYER_QUANTA=<jsonl-path>` records the local player's
-complete admitted object quantum without changing simulation order:
-
-1. quantum start;
-2. root/PositionManager composition;
-3. pre- and post-`UpdatePhysicsInternal`;
-4. transition result;
-5. final collision-response commit.
-
-The accepted repro contained 2,184 quanta. The clearest landing was:
-
-| Quantum | Event | Velocity |
-|---|---|---|
-| 1740 | final airborne quantum | `(-12.316, 8.187, -26.266)` |
-| 1741 | slope collision, normal `(-0.236, 0.236, 0.943)` | |
-| 1741 post-response | correct 5% reflect | `(-17.391, 13.262, -6.576)` |
-| 1742–1758 | still Contact + OnWalkable, no new collision normal | velocity unchanged |
-| 1759+ | contact relationship changes | friction finally begins decaying |
-
-The reflected velocity had `dot(v, normal) = +1.0252`: it pointed away
-from the slope. Retail `calc_friction` correctly skips while this value is
-at least `0.25`, so friction was not the defect. ACDream was repeatedly
-restoring the remembered slope plane and re-grounding the body without
-performing retail's accompanying velocity stop.

-The exact `validate_transition` order at
-`0x0050AAED–0x0050AB42` is:
-
-1. enter only for a non-OK collision/adjusted/slid result;
-2. if `last_known_contact_plane_valid`, call
-   `OBJECTINFO::kill_velocity`;
-3. test the current sphere center against the remembered plane using
-   `radius + 0.0002`;
-4. restore the contact plane only when still within that distance;
-5. later, at `0x0050ACFF`, overwrite last-known validity with final
-   contact-plane validity.
-
-`OBJECTINFO::kill_velocity` calls
-`CPhysicsObj::set_velocity({0,0,0}, 0)`. ACDream had ported the proximity
-test and plane restore but omitted this call. It also allowed the
-last-known plane to re-ground clean accepted moves, although retail only
-consumes it in the non-OK recovery branch.
-
-## Correction
-
-`Transition.ValidateTransition` now:
-
- calls `ObjectInfo.StopVelocity()` before the remembered-plane
-  proximity/restore test on a non-OK recovery;
- performs that restore only in the retail branch;
- overwrites last-known validity from final contact validity, so a clean
-  move away cannot be re-grounded from stale memory.
-
-The existing `PhysicsEngine.ResolveWithTransition` consumption of
-`VelocityKilled` applies the zero to the canonical `PhysicsBody` before
-the collision-response tail. The initial 5% landing reflection remains;
-only a following collision recovery performs the retail stop.
-
-## Gates
-
- New focused pins:
-  - collision recovery with a remembered plane kills velocity;
-  - clean advance with a remembered plane neither kills nor re-grounds.
- Full `AcDream.Core.Tests`: 4,107 passed / 2 skipped.
- Full `AcDream.Runtime.Tests`: 439 passed.
- `AcDream.App` Release build: 0 warnings / 0 errors.
- Complete Release suite: 10,061 passed / 5 skipped / 0 failed.
- User live gate: **PASS** — repeated slope jumps now settle correctly
-  (“Perfect! Works great!”).
-
-## Diagnostic tools retained
-
- `tools/analyze_269_slope_stop_capture.py`
- `tools/cdb/run-issue269-slope-stop.ps1`
- `tools/cdb/issue269-slope-stop.cdb`
-
-The cdb runner refuses to attach unless the live retail executable matches
-the Sept 2013 named PDB. The locally installed 2015 retail executable does
-not match; the static named-retail decode above is therefore the retail
-oracle used for this correction.

-# #271 — Stair-side uphill reversal capture
-
-**Date:** 2026-07-31
-
-**Status:** closed; retail control flow restored and user live gate passed
-
-## Symptom
-
-When the local player ran diagonally uphill while pressing into the side of
-an outdoor staircase, the character could suddenly move backward and rapidly
-slide to the bottom. The symptom was intermittent because it required the
-forward candidate to hit the side wall while the step-down recovery crossed a
-tread edge.
-
-This is not an RDP, render-rate, animation, or gravity symptom. It reproduced
-inside the pure Core collision resolver from one captured input frame.
-
-## Live evidence
-
-The bounded capture is under the ignored local artifact pointer:
-
-`artifacts/issue271-stair-side/LATEST.txt`
-
-It contains 677 local-player physics quanta plus the matching resolver stream.
-The first decisive frame is quantum 310:
-
-```text
-current = (133.03775, 75.53931, 59.608147)
-target  = (133.33783, 76.42308, 59.608147)
-input   = forward + run
-result  = (133.18779, 75.19872, 59.316677)
-normal  = (-1, approximately 0, approximately 0)
-```
-
-The X side-wall collision was valid, but the tangential Y component reversed:
-an uphill request of `+0.88377` produced `-0.34059`. Three frames later,
-quantum 313 snapped from Z `59.52598` to terrain Z `58.005`. A second attempt
-reproduced the same family at quanta 479–482, falling from Z `60.96376` to
-`58.005`.
-
-## Retail oracle
-
-Named retail:
-
- `CTransition::edge_slide` at `0x0050B3D0`
- current-walkable branch at `0x0050B44A`
- no-walkable back-probe at `0x0050B458–0x0050B50F`
- `SPHEREPATH::precipice_slide` at `0x0050CC80`
-
-Retail tests only the current `SPHEREPATH::walkable` pointer. If it is null,
-retail:
-
-1. offsets the failed candidate back to the current sphere center;
-2. runs `step_down` there to rediscover the surface actually under the mover;
-3. restores the failed candidate;
-4. runs `precipice_slide` against the newly discovered polygon; or
-5. returns `COLLIDED_TS` when the back-probe found no walkable polygon.
-
-Retail has no substitution of an older saved walkable polygon in either null
-case.
-
-## ACDream divergence and root cause
-
-`EdgeSlideAfterStepDownFailed` previously called
-`SpherePath.RestoreLastWalkable()`:
-
- before deciding whether to enter the retail back-probe; and
- again when the back-probe found no current walkable polygon.
-
-`LastWalkable` is a separate ACDream history used by the still-open
-CliffSlide compatibility path. At a staircase side wall it could describe the
-preceding tread rather than the surface below the current player position.
-Promoting it into the current slot bypassed retail's back-probe.
-`PrecipiceSlide` then projected the failed forward candidate along the stale
-tread edge, producing the backward/downhill displacement seen in the capture.
-
-The fix removes both stale-history promotions from the edge-slide dispatch.
-Current walkable state still takes retail's direct precipice path; absent
-state now always takes retail's current-position back-probe.
-
-## Deterministic regression
-
-`Issue185OutdoorStairsSeamReplayTests` reuses the captured
-`0x01000AC5` staircase collision fixture and the exact quantum-310 position,
-contact plane, movement delta, player flags, and 1.5 m Setup step-down height.
-
-Pre-fix:
-
-```text
-out = (133.187790, 75.346481, 59.430882)
-```
-
-Fixed:
-
-```text
-out = (133.187790, 76.078186, 60.016247)
-```
-
-The regression requires meaningful positive uphill progress and forbids a
-downhill Z displacement. The complete Core Release suite passes 4,108 tests /
-2 skips; the complete Release solution passes 10,062 tests / 5 skips.
-
-## Live acceptance
-
-The user repeatedly ran uphill while pressing into both sides of the affected
-staircase. Movement remained stable and the former rapid downhill reversal did
-not recur. The client then closed through the normal logout path, with ACE
-confirming graceful logout.

-# Atomic collision-generation activation (Slice 3B)
-
-## Retail anchor
-
-Retail hydrates a cell synchronously. `CObjCell::init_objects`
-(`0x0052B420`) visits objects associated with that cell and invokes
-`CPhysicsObj::recalc_cross_cells` (`0x00515A30`). The final position path also
-replaces shadows as one `SetPositionInternal` operation (`0x00515330`). Retail
-therefore never exposes a world where the new cell exists but the objects that
-overlap it still have their old cross-cell set.
-
-Acdream streams a landblock over several update frames. Literal per-cell
-mutation during those frames was not equivalent: the active `PhysicsDataCache`,
-`CellGraph`, `PhysicsEngine`, buildings, static shadows, and retained-object
-refloods changed at different cursors. Collision queries could observe a mixed
-generation, and correctness depended on a later optional landblock callback.
-
-## Ported adaptation
-
-The asynchronous unit is now one Runtime-owned collision generation:
-
-1. `BeginCollisionAdmission` issues the exact Runtime/landblock generation.
-2. `PrepareCollisionGeneration` creates empty private cache, graph, engine, and
-   shadow facades and retains the active aggregate root reference in O(1).
-   Global immutable GfxObj/Setup catalogs are not copied; the accepted build's
-   exact closure is populated by the existing cursors.
-3. Stable
-   landblock and logical-owner slot suffixes then materialize each non-target
-   cache, CellGraph, engine, and shadow leaf into an empty private root under
-   the host's existing frame meter. The 32-resident-landblock gate proves
-   admission performs no resident copy and every advance reports at most one
-   work unit.
-4. App and Headless publish terrain, EnvCells, topology, buildings, prepared
-   collision assets, and target-root static owners only into that private
-   generation.
-5. Stable per-prefix owner slots capture every non-suspended owner that touches
-   or has a withdrawn repair marker for the target prefix. That includes live
-   dynamic owners and statics rooted in an adjacent landblock. Only a
-   target-root static is omitted, because the authored replacement supersedes
-   it. The scan has a fixed slot suffix and is unaffected by mutations in other
-   prefixes. Vacated slots are tombstoned and reused rather than retained for
-   the whole session. A single Runtime-scoped versioned journal records each
-   mutation once and coalesces repeated changes by logical owner, independently
-   of the number of live drafts. After topology sealing, each draft reconciles
-   the latest exact state of owners changed during that draft's lifetime one
-   owner per seal call. A discovered relevant owner then receives scoped exact
-   updates, preserving continuous-motion progress without restoring global
-   fanout. A membership transition is routed by the owner's changed landblock
-   prefix to the one matching draft, so an owner first entering or leaving the
-   target after its global journal slot was visited is still reconciled once.
-   During topology construction, a visited unrelated owner retains only a cheap
-   coalesced notification; its exact mirror runs later as one metered seal unit
-   rather than once per draft on the mutation path. Once the topology seal
-   exists, observed owners temporarily write through exactly until same-call
-   activation. The finite pre-seal queue therefore drains even when two or more
-   unrelated owners mutate before every host step. Slots predating a newer root snapshot are superseded
-   by a tail slot, not reused behind live cursors. New drafts begin at their
-   captured suffix, obsolete slots compact one visit per seal call, and the
-   journal clears when its last draft closes. Unrelated and continuously moving
-   owners therefore never restart capture or sealing.
-6. Explicit one-work-unit cursors build the complete replacement before the
-   activation frame: requested global collision records, cells/topology,
-   buildings, cell graph removals, affected static owners, retained-owner
-   states, and removal lists. A late unarmed relevant owner consumes at most
-   one refresh unit on a seal call; when that drains the queue an already-built
-   seal is immediately ready. Immutable global GfxObj/Setup closure entries are
-   preinstalled during these metered steps, not during activation.
-7. Cache, CellGraph, engine-landblock, and shadow topology share one
-   `CollisionWorldStateSlot`. `CommitCollisionGeneration` transfers the
-   complete off-side aggregate through one volatile reference on the update
-   thread, then revokes the staging slot. The public `PhysicsDataCache`,
-   `CellGraph`, `PhysicsEngine`, and `ShadowObjectRegistry` facade identities
-   stay stable. Warm 256-owner, cold
-   first-load, changed EnvCell/building, and new static-bucket gates all measure
-   exactly zero managed bytes in final activation. Only afterwards does Runtime
-   emit `CollisionGenerationCommitted` and a ready acknowledgement.
-8. Multiple landblocks may prepare concurrently. Preparation order is the
-   activation order. Only after an older generation commits is its exact delta
-   queued into every later draft. Each additional seal call applies at most one
-   cache, CellGraph, synthesized outdoor-cell, engine-landblock, or logical
-   owner leaf. Later generations retain their own completed target seal but
-   cannot activate before every committed delta drains. Cancelled older drafts
-   therefore contribute nothing, final activation performs no peer work, and a
-   later root cannot overwrite or expose an older snapshot. Seam-crossing
-   statics are forcibly re-evaluated against the later topology. Demotion and
-   withdrawal cancel a matching queued or active rebase, suppress that prefix
-   in unfinished source scans, and retire one shadow owner, cache/graph leaf,
-   authored outdoor cell, or landblock leaf per later seal call before
-   activation. Retirement storage is growable rather than coupled to the
-   concurrent-preparation limit, and final commit rechecks both pending rebase
-   and retirement work after the seal-to-commit gap.
-   The host performs the zero-work root transfer in the same update-thread call
-   that completes final reconciliation, eliminating a seal-to-next-frame quiet
-   window for continuously moving unrelated owners.
-9. GfxObj/Setup closure entries are immutable content-addressed catalog data,
-   not world topology. Their metered early installation may survive a cancelled
-   generation as ordinary process cache residency; no cell, building,
-   landblock, or shadow becomes visible through that catalog alone.
-
-Presentation and no-window hosts use the same Runtime transaction. Network
-workers still enqueue immutable messages and cannot mutate collision or shadow
-state.
-
-## Failure and lifetime rules
-
- A newer admission invalidates an older prepared generation.
- Cancellation names one admission and its private staging generation. It can
-  never withdraw or demote the active landblock, and cancelling a stale receipt
-  cannot invalidate a newer admission.
- Demotion, withdrawal, reset, and disposal invalidate the admission before
-  changing the active generation.
- Disposing a stale/cancelled prepared generation clears only its private
-  engine/cache/shadows.
- The prior complete generation remains queryable throughout preparation.
- The commit notification is the future lost-cell-registry seam. Slice 3B does
-  not implement `GotoLostCell` or change `SetPosition` recovery behavior.
-
-## Deterministic evidence
-
-The focused Runtime/App tests pin:
-
- previous terrain/cells/buildings/statics remain visible until commit;
- exactly one notification after a successful complete activation;
- stale admission replacement has no active-world side effect;
- unrelated movement on every capture/seal step never restarts the target;
- two relevant owners moving on every seal step converge without restarting
-  the topology meter and install their latest positions at activation;
- an authoritative state change on a retained rowless owner updates an
-  already-sealed generation without a global restart;
- a neighboring static whose shadow crossed the seam is restored atomically
-  on reload and its withdrawn-prefix marker clears only at activation;
- a late spawn blocks activation until its one metered refresh; deletion of an
-  armed owner writes through directly;
- Headless faults immediately after admission and after staging preserve the
-  prior complete world and leave no collision admission behind;
- dense sealing consumes at most one work unit per call, while warm 256-owner,
-  cold first-load, changed EnvCell/building, and new static-bucket activation
-  all allocate zero managed bytes;
- concurrently prepared landblocks rebase and preserve both terrain roots and
-  static-shadow owners across their activation order, with zero-byte final
-  commits and revoked staging access;
- dense 32-landblock admission performs no resident copy, stays within its
-  constant allocation envelope, and materializes at most one leaf per advance;
- cancelled older drafts contribute no topology to later roots, while a live
-  owner mutation after the older commit wins over the queued rebase;
- a newly committed seam-crossing static refloods against the later draft's
-  topology before that draft may activate;
- post-seal arrivals drain one owner per seal call without resetting capture;
- an unrelated owner entering the target after its journal slot was visited is
-  routed by prefix and reconciled in one metered seal unit;
- target departure and same-ID reuse preserve the exact new-prefix owner rows;
- unrelated state mutation publishes only after every row changes;
- unrelated demotion/withdrawal and the live `CurrCell` cannot be resurrected
-  or rolled back by a later draft;
- queued and partially applied peer rebases cannot resurrect a later demoted or
-  withdrawn landblock;
- deleting an outgoing target static before, during, or after staging cannot
-  erase an authored same-ID replacement;
- 10,000 repeated mutations with 32 drafts retain one coalesced journal entry
-  and allocate no more than the owner mutation itself;
- 512 unique changed owners reconcile in exactly 512 metered seal units and
-  the final activation still allocates zero managed bytes;
- compacted journal slots are never reused behind a live cursor, while a
-  4,096-slot obsolete tail retires incrementally and a later draft starts at
-  its captured suffix rather than scanning old tombstones;
- post-seal retirement blocks activation until its cursor drains, and more
-  than 256 distinct retirements remain metered and lossless;
- prefix-owner slots remain bounded under GUID churn and empty containers are
-  reclaimed across unique prefixes without invalidating a live seal cursor;
- graphical and no-window publishers use the same Runtime transaction;
- removal and terminal teardown converge the active ownership ledger.
-
-This retires divergence row AD-6. The remaining lost-cell state-machine work is
-deliberately outside this slice.

-# Canonical retail `SetPosition` — placement/streaming Slice 4A
-
-## Scope
-
-This note pins the pure physics half of the placement/streaming closeout.
-Slice 4A lands the retail placement transaction as a separately testable Core
-mechanism. It deliberately does **not** replace the production snap-only
-resolver yet: Runtime lost-cell ownership and the complete inbound-route
-cutover remain Slice 4B. AP-1 and AD-1 therefore remain active until that
-cutover is complete.

-
-```text
-SetPosition(request):
-    transition = makeTransition()              // GENERAL_FAILURE if none
-    init_object(transition, object)
-
-    if the PartArray has no spheres:
-        init_sphere(1, dummy center=(0,0,0.1), radius=0.1, scale=1)
-    else:
-        init_sphere(first min(count,2) authored spheres, exact object scale)

-    AdjustPosition(request frame, first sphere, noCreate=(flags & 0x20))
-    if no resident cell:
-        store the adjusted authoritative frame and enter lost-cell lifetime

-    if transition.curr_cell == null:
-        return NO_CELL
-    commit the complete transition
-    return OK
-```
-
-`AdjustPosition` branches on the claimed cell shape. A direct outdoor claim
-runs pure `LandDefs::adjust_to_outside` normalization before visible-cell
-lookup. An indoor claim first resolves the visible cell and child; only a
-resident indoor cell marked `seen_outside` falls back to outdoor
-normalization. An absent indoor cell (including the `0xFFFF` sentinel) remains
-the exact claimed cell/frame. A map-edge outdoor normalization failure stores
-cell zero with the otherwise unchanged frame. The old `max(terrainZ, z)` lift
-and nearest-in-Z scan do not occur in this canonical mechanism.
-
-`CheckPositionInternal` calls the complete placement transition. Without the
-slide flag, retail accepts the result only when signed
-`resolvedX-requestedX <= 0.0500000007`, the same signed Y condition holds, and
-the cell is unchanged. Z is not part of that predicate. The resolved origin is
-accepted while the requested orientation remains intact.
-
-## Two validators, not one
-
-The similarly named retail helpers have different contracts and stay separate
-in the port:
-
- `validate_placement_transition` is the inner `find_placement_pos` validator.
-  Any non-OK state from `COLLIDED` through `SLID`, when sliding is permitted,
-  resets `COLLISIONINFO`; it never retries placement.
- `validate_placement` is the outer initial/final validator. Only `ADJUSTED`
-  or `SLID`, and only while its retry argument is true, performs one
-  `placement_insert`; `COLLIDED` neither resets nor retries.
-
-Step-down is disabled only for missiles. For fewer than two spheres retail
-first clamps the requested height to half the radius when the sphere diameter
-is less than or equal to that height. It then performs one full probe when the
-diameter is greater than the resulting height, otherwise two half probes.
-Equality belongs to the two-half-probe branch.
-
-## Modern seam
-
-`PhysicsEngine.SetPosition` returns one immutable
-`PhysicsSetPositionResult`. `SetPositionError` retains the header values
-(`OK=0`, `GENERAL=1`, `NO_VALID=2`, `NO_CELL=3`, `COLLIDED=4`,
-`INVALID_ARGS=0x100`) while `PhysicsResidenceDisposition` separately reports
-`Committed`, `DeferredCell`, or `Unchanged`. Missing content is therefore
-successful-but-deferred, never misreported as a placement failure.
-
-The result carries the complete commit packet: root/cell-local frame,
-contact/walkable/water state, sliding and collision normals, stationary-fall
-counter, a complete immutable `COLLISIONINFO` snapshot for the real
-`handle_all_collisions` callback (including contact/last-contact, sliding,
-collision normal, stationary-fall, environment, adjustment, and object
-fields), the callback result, and an explicit shadow action. A PhysicsBSP or changed-cell force commit
-requests canonical shadow recalculation; a non-BSP transition replaces its
-shadows only when the transition produced a nonempty cell array, otherwise it
-preserves the prior list. Unchanged force placement changes only the frame.
-
-Core never creates cells synchronously, so retail flag `0x20`
-(`DoNotCreateCells`) has no differential loader branch inside this pure
-mechanism. Both flag states can only observe already-published immutable cell
-content and otherwise return `DeferredCell`. Carrying the flag into exact-cell,
-generation-scoped async admission is part of the still-open Slice 4B
-adaptation tracked with AD-2; this slice does not claim a dead SpherePath field
-as exact behavior.
-
-The existing public `Resolve` compatibility entry remains entirely unchanged
-for production movement and zero-delta callers. Its result cannot represent a
-successful-but-deferred residence, so hiding `DeferredCell` inside
-`ResolveResult.Ok` would corrupt the contract. Slice 4B will route every
-authoritative placement family through `SetPosition`, atomically install its
-packet, and own exact lost-cell wakeup/commit.
-
-## Automated oracle
-
-`PhysicsSetPositionTests` pins error values, absent/invalid outdoor and indoor
-claims, cross-landblock frame normalization, map-edge failure and the `0xFFFF`
-sentinel, dummy/authored sphere setup, nonpositive scale, Ethereal seeding,
-explicit-only PathClipped, missile step-down, exact equality schedules, both validators,
-the late compass sample's float bits, signed no-slide behavior, actual
-collision-handler mapping, force-class policy, explicit shadow actions, null
-current-cell wakeup, ten-record scratch exhaustion, exact scatter ordering,
-failed-probe scratch lifetime, and deferred-scatter stop. The legacy public
-Resolve fixture remains unchanged until Slice 4B.
-
-## Slice 4B1 — Runtime residence owner
-
-Slice 4B1 adds the presentation-independent half of the cutover without
-changing a production graphical route yet. `RuntimeSetPositionState` accepts
-an exact entity/position token before graphical DAT preparation, consumes the
-immutable Core result, and commits body, contact, full cell, shadows, object
-clock, and Runtime spatial worksets before publishing one ordered placement
-delta. The delta carries the exact `RuntimeEntityKey`, session lifetime,
-position/spatial/placement versions, adjusted cell, collision generation, and
-optional portal-authority shape. A throwing or unavailable host does not roll
-simulation back: Runtime republishes the same projection token until the
-exact FIFO head is acknowledged. A newer operation changes an already-
-published token to `Discard` and increments its projection revision, so an
-acknowledgement of the previously observed Place/Withdraw cannot consume an
-unseen Discard. It is never silently forgotten. An unacknowledged lost-cell
-Withdraw transfers intact to a replacing accepted operation and remains the
-FIFO head before that replacement may publish Place.
-
-The successful missing-cell path owns retail's residence shape:
-
-```text
-SetPosition -> OK + DeferredCell
-    retain adjusted Position and the same PhysicsBody/components
-    clear only Active and suspend the object clock
-    withdraw Runtime spatial worksets and shadow rows
-    retain shadow registration and exact authored mover request
-    append parentless root to (exact cell, collision generation)
-    arm independent exact-key 25 s deadlines for root + direct children
-    publish Withdraw
-
-exact cell generation resident + Withdraw acknowledged
-    re-run SetPosition with retained authored spheres and CurrentCellId=null
-    atomically install complete result
-    publish Place
-```
-
-Lost-cell membership buckets use retail-shaped append plus swap-remove.
-Destruction deadlines use an exact-key hash plus a bounded indexed min-heap,
-the allocation-bounded modern equivalent of retail's hash +
-`PQueueArray<double>` priority owner. Rearm/removal updates the exact heap node;
-there are no stale tombstones. Only committed, current direct children from
-the parent-incarnation ordered CHILDLIST participate; unresolved or future
-relations cannot inherit a deadline. Parent, pickup, delete, GUID
-replacement, newer Position, reset, and disposal cancel the exact incarnation
-and use leave-world semantics rather than a wakeable lost entry. The dormant
-collision-retirement entry parks non-static parentless indoor roots and, for
-complete withdrawal, affected outdoor roots. It performs a complete preflight
-and rejects overlap with any active accepted/host-ack-pending placement before
-mutating one resident. It then installs every affected canonical lost
-residence and operation before publishing the first synchronous Withdraw, so
-an observer re-entering for a later root inherits that root's exact pending
-Withdraw instead of having its newly accepted placement cancelled by the
-retirement loop. 4B2 must quiesce that placement prefix before invoking the
-entry in the same transaction that installs host acknowledgements.
-
-Runtime retains the last accepted prepared mover request, including exact
-off-center/two-sphere payloads, scale, flags, and step values. A cold resident
-with no prepared request still withdraws atomically but remains explicitly in
-`AwaitingPreparation`; it cannot wake through an invented empty-sphere shape.
-Preparation is cached only after Core accepts it as Committed or DeferredCell.
-A rejected/malformed preparation keeps the same accepted token retryable and
-cannot replace the last validated mover used by later collision retirement.
-Runtime's host boundary rejects only non-finite consumed frame/shape values;
-retail-valid oddities such as nonpositive authored scale remain untouched.
-Likewise, a non-deferred wake failure retains the withdrawn body, independent
-25-second lifetime, and exact operation: invalid arguments return to
-AwaitingPreparation and re-index for the next exact generation, while other
-world-placement failures also re-index. The last successful DeferredCell
-result and adjusted frame remain canonical across the failed attempt. No
-failed wake can leave a live entity withdrawn without a Runtime owner. The
-graphical/no-window cutover in 4B2 supplies that exact preparation token.
-
-Retail `CPhysicsObj::SetPositionInternal` (`0x00515BD0`) calls
-`prepare_to_enter_world` (`0x00511FA0`) only when `this->cell == 0`.
-Consequently the physics `update_time` (`PhysicsBody.LastUpdateTime`) and
-active bit are reset only on the cellless-to-world edge. Ordinary same-cell or
-cross-cell in-world SetPosition preserves the already-consumed physics clock;
-entering the lost-cell residence also preserves it until the eventual
-cellless wake commit. Runtime pins both sides and does not inherit the older
-graphical teleport helper's unconditional timer reset.
-
-The wake timestamp is in the Runtime simulation-time domain, never Unix/UTC:
-`GameRuntime` binds its instance `GameRuntimeClock` through the entity/physics
-owner, and RetryDeferred samples `SimulationTimeSeconds`. Standalone Runtime
-fixtures without a bound game clock retain the accepted command time. This is
-a Runtime dependency only; no App delegate enters the owner.
-
-The canonical commit also installs every SetPosition-derived body invariant
-before host publication: Contact/OnWalkable/WaterContact, the current contact
-plane and slope `GroundNormal`, Sliding plus its normal, and the complete
-StationaryFall/Stop/Stuck encoding. Named retail
-`CPhysicsObj::SetPositionInternal(CTransition const*)` (`0x00515330`) copies
-only the transition's current contact plane/water flag, walkability, sliding
-normal/valid flag, and collision state (`0x005153E5–0x005154FE`). It does not
-publish `last_known_contact_plane` or the SpherePath walkable polygon on this
-path, so those ordinary-update-only fields are intentionally absent from the
-immutable SetPosition result and remain unchanged. A zero expected velocity
-version in host preparation preserves the nonzero version captured when the
-operation was accepted; an intervening Vector/Movement therefore suppresses
-only the stale collision-velocity response. A bodyless cancellation terminates
-without fabricating a PhysicsBody or a host Withdraw projection. The two time
-domains remain explicit: `PhysicsBody.LastUpdateTime` consumes the instance
-simulation clock, while `IRuntimeRemotePlacement.LastServerPositionTime`
-remains Unix-UTC receipt time because the remote stale-velocity owner ages it
-against `RuntimePhysicsState.UtcNowSeconds`. A deferred wake therefore cannot
-make fresh authoritative remote velocity appear years old. Runtime preparation
-also applies the existing retail `PositionFrameValidation` before Core or
-prepared-mover caching, and caps synchronous Scatter/RandomScatter work at 64
-attempts; this keeps valid authored retail request shapes while rejecting a
-hostile `uint.MaxValue` loop at the authority boundary.
-
-One authority boundary intentionally remains open for 4B2:
-
- `RuntimePortalPlacementAuthority` validates immutable token shape only;
-  4B2 must bind it to active `RuntimeWorldTransitState` generation, teleport
-  sequence, destination, and host acknowledgement before reveal.
-
-The former collision-report boundary is closed by
-`RuntimeCollisionReportingState`. Runtime now owns retail's exact-key object
-contact table, environment latch, strict ordinary/ethereal expiry, force-end,
-static and `ReportAsEnvironment` routing, reciprocal callback eligibility,
-missile-state clearing, ordered reentrant dispatch, and the report-result
-boolean which distinguishes placement `Collided` from `NoValidPosition`.
-Successful SetPosition commits reporting after Contact/OnWalkable and ground
-callbacks but before its single physical response and shadow reflood. See
-`docs/research/2026-07-31-runtime-set-position-collision-reporting.md`.
-
-### Slice 4B2 checkpoint 1 — public dormant host seam
-
-The first 4B2 checkpoint exposes the dormant receipt owner through
-`RuntimePlacementProjectionChannel`. Graphical and no-window hosts can observe
-the one ordered placement stream, retry the exact immutable pending receipts,
-peek the FIFO head, measure pending debt, and acknowledge only the exact head.
-Mutation and retry calls require the current `RuntimeGenerationToken`; a stale
-generation, stale revision, reordered token, duplicate acknowledgement, or
-reused GUID cannot consume current placement debt. The channel delegates to
-`RuntimeSetPositionState` and `RuntimeEntityObjectEventStream`; it owns no
-second queue, mirror, or rollback path.
-
-Shared local-controller body adoption is deliberately deferred. A reviewed
-prototype that prepared directly on the canonical body was rejected: a
-snapshot/rollback lease cannot safely coexist with reentrant SetPosition,
-remote/projectile binding, deletion/GUID reuse, owner replacement, object-clock
-epoch changes, or disposal. Correct adoption requires either an exclusive
-Runtime transaction integrated with every canonical writer, or off-canonical
-preparation followed by one validated atomic body/controller publication.
-Either choice belongs to the all-route ownership cutover, not this narrow
-dormant-seam checkpoint.
-
-This remains a deliberately non-activating checkpoint. Production spawn,
-Position, projectile, drop/pickup/parent, and portal routes do not submit to
-the dormant SetPosition owner yet. The cutover remains blocked on exact
-ordered Setup spheres/scale/step heights/flags/cell-local preparation,
-presentation-only rebucketing, and placement-prefix quiescence before
-collision retirement. AP-1 and AD-1 remain open until those prerequisites and
-every production route land together.
-
-AD-2 remains the explicit async adaptation: collision readiness can publish in
-a different frame from retail's blocking load. A failed wake is safely re-
-indexed to the next exact generation instead of inheriting retail's
-synchronous assumption. When older unbound survivors meet newer entities
-already indexed into that future generation, Runtime merges them into one
-bucket with the older survivor order first and retains one bucket-order entry.
-AP-1 and AD-1 remain open until 4B2 removes the legacy graphical/headless
-placement paths.
-
-`RuntimeSetPositionStateTests` pins accepted-before-preparation ownership,
-portal-shape rejection, canonical-before-projection ordering, retry and
-reentrant discard, cross-landblock adjusted-cell park/wake, same-body
-identity, retained contact/water/sliding/velocity, exact generation gating,
-authored two-sphere retention, cold preparation, bounded priority-deadline
-rearm/cancel, zero-allocation empty ticks, independent ordered direct-child
-deadlines, actual collision-admission supersession/invalidation, missing exact
-indoor-cell generation rebind/wake, collision demotion/withdrawal preflight,
-failed-wake retry, malformed-preparation retry without cache poisoning,
-simulation-clock-domain wake, velocity-version preservation, derived body-bit
-writeback, immediate remote-velocity survival across the simulation/UTC clock
-boundary, invalid cell/frame/quaternion and extreme-scatter rejection before
-Core/caching, bodyless cancellation, newer Position/pickup/parent/delete, GUID
-reuse, reset, and complete index/node terminal convergence. Existing zero-
-allocation collision-generation gates remain unchanged on the no-deferred
-fast path.
-
-The warmed immediate commit/ack route currently measures exactly **1,880
-managed bytes per operation** in the Release Runtime test host (1,000
-iterations after 64 warmups); the regression gate caps it at 2,048 bytes.
-This dormant-path result is an explicit 4B2 activation blocker rather than a
-claim of allocation-free production readiness: 4B2 must either pool/remove
-the operation and projection envelopes or record an approved measured budget
-before routing frame-frequency placement through this owner.

-# Retail cell availability and containment-root validation — 2026-07-31
-
-## Scope
-
-This note closes divergence rows AD-3 and AD-4. It does not begin AD-6's
-atomic streaming-generation work.
-
-The corrected port distinguishes these states:
-
-1. no visible cell payload is loaded;
-2. a malformed raw/prepared payload has no containment root;
-3. a loaded CellStruct has a valid authored containment root (its physics root
-   may independently be absent).
-
-Only (3) is published. State (1) remains unavailable and retryable. State (2)
-is quarantined atomically so a later valid hydration can retry; it must not
-become a world-wide containing cell.
-
-## Installed-data audit
-
-The complete installed EoR catalog and matching prepared package were audited
-before choosing this invariant:
-
- enumerated EnvCells: **729,888**;
- raw: 0 missing EnvCells, 0 missing Environments, 0 missing CellStructs,
-  0 null `CellBSP` objects, **0 null `CellBSP.Root`**, 729,888 valid roots;
- prepared `acdream.pak`: 0 missing aliases, 0 corrupt payloads,
-  **0 `ContainmentBsp.RootIndex < 0`**, 729,888 valid roots;
- 6,940 raw EnvCells have zero portals, so the retail portal-pointer guard is
-  a real catalog path rather than dead defensive code.
-
-There are therefore no root-null record IDs to preserve in either source.
-
-## Retail oracle
-
-`CObjCell::find_cell_list @ 0x0052B4E0` in
-`docs/research/named-retail/acclient_2013_pseudo_c.txt:308742` establishes the
-availability gates:
-
- `CEnvCell::GetVisible` / `CLandCell::GetVisible` resolves the active seed at
-  `0x0052B50C..0x0052B515`;
- the outdoor branch still calls `CLandCell::add_all_outside_cells` at
-  `0x0052B53F`, even when that seed lookup returned null;
- the complete growing-array transit walk and containing-cell pick are gated
-  by `seed != null && num_spheres != 0` at `0x0052B576`;
- each later candidate is independently skipped when its stored cell pointer
-  is null at `0x0052B58E`.
-
-`CEnvCell::point_in_cell @ 0x0052C300` first returns false when
-`this->portals == 0`, then transforms the point and calls
-`CCellStruct::point_in_cell`.
-
-`CCellStruct::point_in_cell @ 0x005338F0` calls
-`BSPTREE::point_inside_cell_bsp @ 0x005398C0`, which immediately invokes
-`BSPNODE::point_inside_cell_bsp(this->root_node, ...)`. The BSP node method at
-`0x0053C1F0` dereferences `this` before walking positive children. Only a
-missing **positive child below a valid root** is the inside terminal case. A
-missing root is not.
-
-## Ported behavior
-
- `PhysicsDataCache` publishes graph, collision, and prepared records only
-  after a valid raw/prepared containment root is present. A missing physics
-  root is retained as a valid non-colliding cell. Invalid containment
-  publication changes no cache, so later hydration can retry.
- `CollisionTraversal.HasCellContainment` tests `Root` / `RootIndex`.
- Both raw and prepared `EnvCell.PointInCell` paths apply the zero-portals
-  guard before containment. `CellTransit` applies the same guard to its
-  `CellPhysics` representation.
- `CellTransit.BuildShadowCellSet` still seeds all overlapped outdoor cells,
-  but skips the transit walk when the active outdoor seed cannot be resolved
-  from `CellGraph`. Every later outdoor candidate independently resolves via
-  `GetVisible` before building transit, so a stale building cannot promote an
-  object through an unavailable adjacent landcell.
- The existing reflood lifecycle remains the recovery mechanism. Once terrain
-  or a valid indoor CellStruct publishes, the next reflood walks the authored
-  portal/building relationships without reconstructing a different rule.
-
-## Gates
-
-Focused tests cover raw/prepared rootless quarantine and valid retry, valid
-containment with missing physics, raw/prepared zero-portal parity, indoor and
-outdoor seeds, preservation of outside-cell seeding, per-candidate adjacent
-landcell availability, suppression of stale-building promotion, and
-hydration/reflood recovery. The corrective checkpoint passes:
-
- focused cell-availability suite: **54/54**;
- Core Release: **4,165 passed / 1 skipped**;
- Runtime Release: **440/440**;
- App Release: **4,002 passed / 3 skipped**;
- complete Release solution: **10,122 passed / 4 skipped**;
- `dotnet build AcDream.slnx -c Release`: **0 warnings / 0 errors**.

-# Issue #273 — Holtburg tight-gap support validation
-
-**Date:** 2026-07-31
-**Status:** implementation, automated gates, and exact live gate pass
-**Scope:** grounded player step-down support at a floor edge beside a static
-cylinder
-
-## Captured scene
-
-The reproducible gap is in outdoor cell `0xA9B40032`, between:
-
- building shell GfxObj `0x01000F69`, placed at
-  `(158.178, 37.7055, 94.0)` with quaternion
-  `(w=.939319, x=0, y=0, z=-.343045)`;
- static post `0xCA9B4027`, placed at `(160.173, 34.487, 95.975)`,
-  represented by its Setup-authored cylinder (`radius=.282`,
-  `height=5.564`);
- the local player Setup's exact two spheres (`radius=.48`, origins
-  `z=.475` and `z=1.35`).
-
-The building's supporting ledge terminates at local `x=4`. The first
-post-side response moved the player's foot-sphere center to approximately
-local `x=4.33`. The full `.48` movement sphere still overlapped the floor, so
-the existing step-down path accepted the candidate. Repeated frames then
-carried the player around the post and outside the building shell.
-
-The fixture
-`tests/AcDream.Core.Tests/Fixtures/issue273/0x01000F69.gfxobj.json` preserves
-the installed DAT PhysicsBSP. The replay in
-`Issue273HoltburgTightGapReplayTests` uses the captured object placement,
-player spheres, static posts, and movement offsets.
-
-## Retail mechanism
-
-The missing rule is not extra collision padding and is not a larger player
-sphere. It is retail's second-stage support validation:
-
-1. `CTransition::step_down` (`0x0050B2A0`) performs the ordinary downward
-   collision probe.
-2. After finding a walkable contact plane, an EdgeSlide mover that is not in
-   StepUp calls `CTransition::check_walkable` (`0x0050AFF0`). The binary
-   sequence is `test ah,2` at `0x0050B36A`, which is state bit `0x200`
-   (`EdgeSlide`), followed by the `step_up == 0` test and call at
-   `0x0050B380`.
-3. `CTransition::check_walkable` first calls
-   `SPHEREPATH::check_walkables` (`0x0050C3E0`).
-4. `SPHEREPATH::check_walkables` halves the saved foot-sphere radius and
-   calls `CPolygon::check_walkable` (`0x00538E60`).
-5. If the remembered polygon does not support that smaller sphere,
-   `CTransition::check_walkable` performs a downward CheckWalkable insertion.
-   BSP leaves require both `walkable_hits_sphere` and
-   `CPolygon::check_small_walkable` (`BSPLEAF::hits_walkable`,
-   `0x0053D670`).
-6. If neither check finds support, `CTransition::step_down` rejects the
-   candidate and the existing edge-response chain handles it.
-
-ACDream already had the small-radius BSP-leaf test, but
-`DoCheckWalkable` treated the mere presence of a remembered polygon as
-success, and the ordinary `DoStepDown(..., runPlacement:false)` path never
-called it. This let a full-radius overlap stand in for actual foot support.
-
-## Port
-
- `BSPQuery.CheckWalkableSupport` is the shared resolved-polygon form of
-  retail `CPolygon::check_walkable`.
- `SpherePath.CheckWalkables` implements the retail half-radius remembered
-  polygon check without mutating canonical sphere state.
- `Transition.DoCheckWalkable` now tests the remembered polygon rather than
-  treating a non-null polygon as sufficient.
- `Transition.DoStepDown` restores the EdgeSlide/non-StepUp support gate
-  before the existing placement-policy seam.
-
-There are no location checks, object IDs, guessed radii, widened collision
-shapes, or gap-specific tolerances in the production fix.
-
-## Regression impact
-
-The existing #271 staircase-side replay begins with its center `.288 m`
-outside a tread whose retail half-radius support boundary is `.24 m`.
-Retail may therefore stop that exact candidate. The test now preserves the
-original user-visible invariant—never reverse or accelerate downhill—without
-requiring forward progress beyond retail's support boundary. The ordinary
-continuous staircase replay still requires and achieves forward progress.
-
-## Gates
-
- issue #273 fixture/replay: 3 passed;
- focused BSP, step-up, edge-slide, #185/#271 family: 42 passed / 1 skipped;
- complete Core tests: 4,111 passed / 2 skipped;
- Release solution build: passed;
- complete Release solution tests: 10,068 passed / 5 skipped.
-
-The user accepted the exact in-client Holtburg gap gate on 2026-07-31: the
-gap blocks from the tested approach, and the adjacent movement checks remain
-healthy.

-# Remaining physics-divergence campaign handoff — 2026-07-31
-
-> **Checkpoint 2 update:** Slice 4B2 prerequisite A, Runtime SetPosition
-> collision-report ownership, is implemented in the next checkpoint. Continue
-> with the dedicated
-> [`runtime SetPosition collision-reporting handoff`](2026-07-31-runtime-set-position-collision-reporting-handoff.md),
-> not the prerequisite-A instructions preserved below as historical context.
-
-## Purpose and stopping point
-
-This is the deliberate handoff boundary requested after placement Slice 4B2
-checkpoint 1. The repository is stopped before any production graphical or
-headless route submits to the canonical Runtime SetPosition owner.
-
-The completed foundation is useful and tested, but the overall campaign is
-**not complete**. AP-1 and AD-1 remain narrowed/open. AP-22 and AD-10 remain
-open. Do not retire those rows until their exact automated and connected gates
-pass.
-
-### Exact workspace
-
- Worktree: `C:\Users\erikn\.codex\worktrees\af5e\acdream`
- Branch: `codex/port-claude-agents`
- Handoff code checkpoint: `270f5154`
-  (`feat(runtime): expose dormant placement receipts`)
- Immediately preceding residence-owner checkpoint: `4c02ac42`
-  (`feat(runtime): own deferred set-position residence`)
- Pure Core SetPosition checkpoint: `e84a388e`
-  (`feat(physics): port canonical retail set-position core`)
- No upstream is configured for this worktree branch.
- Remotes:
-  - `origin`: `https://git.snakedesert.se/erik/acdream.git`
-  - `github`: `git@github.com:eriknihlen/acdream.git`
-
-The handoff was written in this same worktree. The next agent should continue
-there rather than creating a different worktree unless the user explicitly
-requests it.
-
-## Worktree hygiene
-
-The worktree intentionally reports unrelated modifications. Preserve them.
-Never use `git add -A`, `git reset --hard`, or checkout/revert commands against
-these paths.
-
-At the checkpoint, `AGENTS.md` has a real unrelated content diff. The following
-paths report modified due to existing line-ending/stat noise but have no
-content diff against the index:
-
- `src/AcDream.App/Input/PlayerModeController.cs`
- `src/AcDream.App/Interaction/PlayerInteractionMovementSink.cs`
- `src/AcDream.App/Rendering/LiveAnimationPresentationContext.cs`
- `src/AcDream.App/World/LiveEntityRuntime.cs`
- `src/AcDream.Core/Physics/CellArray.cs`
- `src/AcDream.Core/Physics/PhysicsBody.cs`
- `src/AcDream.Headless/Hosting/HeadlessSessionWorldProjection.cs`
- `src/AcDream.Runtime/Gameplay/PlayerMovementController.cs`
- `src/AcDream.Runtime/Physics/RuntimePhysicsState.cs`

-git diff --cached --stat
-git status --short
-```
-
-## What is complete
-
-### Campaign baseline and issue #273
-
- `c24bc571` — retail StepDown support-radius behavior for tight gaps.
- `10b55d74` — tight-gap controls and diagnostics.
-
-### Retail retry and edge/StepDown dispatcher
-
- `e5f855ac` — nested per-cell collision retries.
- `67d1e9b3` — refreshed-cell retry state.
- `4ca7230b` — retained cell across inner retries.
- `c559c48d` — retail edge-response ordering.
- `4fbd93ec` — edge-slide stop semantics.
- `1fd5da67` — StepDown placement validation.
- `acec33ec` — StepDown probe state.
- `75b6f6b6` — Path-6 collision response.
- `d3c0d9ec` — TS-4 production chronology gate.
-
-These retire AP-3, AP-4, AP-5, AD-53, AD-54, and TS-4 under the tests and
-research already recorded in the divergence register.
-
-### Exact cell availability and atomic collision generations
-
- `7716c2ee` — retail cell-availability semantics.
- `3e0f3b62` — containment-root validation.
- `be94bc9b` — atomic collision-generation activation.
- `d94145e6` — seal before activation.
- `6b28ff99` — starvation-free activation.
-
-These retire AD-3, AD-4, and AD-6. The active collision world remains visible
-until a complete replacement generation is atomically committed.
-
-### Canonical SetPosition Core and Runtime residence owner
-
- `e84a388e` ports the pure Core SetPosition transaction.
- `4c02ac42` adds `RuntimeSetPositionState`, including:
-  - exact accepted operation ownership;
-  - canonical body/contact/cell/shadow/workset commit;
-  - authored mover retention;
-  - exact-cell and collision-generation wake;
-  - 25-second root/direct-child lost-cell lifetime;
-  - bounded indexed deadline structures;
-  - revisioned ordered Withdraw/Place/Discard host receipts;
-  - cancellation/GUID-reuse/reset/disposal convergence;
-  - structural cell/quaternion validation and bounded scatter work.
- `270f5154` adds `RuntimePlacementProjectionChannel`, a public,
-  generation-gated host seam over the one existing receipt owner:
-  - subscribe to ordered immutable receipts;
-  - peek the exact FIFO head;
-  - retry pending receipts without recommitting Runtime state;
-  - acknowledge only the exact current FIFO-head token;
-  - observe pending receipt debt.
-
-The channel owns no second queue and has no App or Headless production
-consumer. A source guard pins that dormancy. This is intentional.
-
-### Validation at the stopping point
-
-The final channel-only checkpoint passed:
-
- Release solution build: 0 errors, 18 existing warnings.
- Complete Release suite: 10,279 passed, 4 skipped, 0 failed.
- Runtime SetPosition focused tests: 47/47.
- App dormancy/ownership guards: 3/3.
- `git diff --check`: clean.
- Retail-conformance re-review: clean.
- Architecture/adversarial re-review: clean.
-
-## Rejected prototype — do not resurrect it
-
-A prototype made graphical and headless `PlayerMovementController` instances
-borrow the canonical `RuntimeEntityRecord.PhysicsBody` immediately and used a
-snapshot/rollback lease to recover from late construction failures. It was
-fully removed before `270f5154`.
-
-The design was rejected because it was failure-atomic only without
-reentrancy. While the lease was open, a nested SetPosition, remote/projectile
-bind or update, deletion/GUID replacement, object-clock epoch change, or
-disposal could establish newer authority. The outer rollback could then erase
-that newer commit or detach a body already used by another canonical owner.
-
-The next implementation must use one of these complete solutions:
-
-1. A Runtime-owned exclusive/versioned controller/body publication
-   transaction respected by **every** canonical body writer, binding path,
-   SetPosition operation, clock epoch transition, deletion, reset, and
-   disposal; or
-2. Off-canonical preparation followed by one validated atomic Runtime commit
-   that publishes the prepared controller/body relationship without copying
-   stale state over newer authority.
-
-Because every writer must participate, this belongs to the atomic production
-route cutover. Do not reintroduce a local snapshot lease or a Commit method
-that merely checks the body reference at the end.
-
-## What remains — required execution order
-
-### Slice 4B2 prerequisite A — real collision-report ownership
-
-`RuntimePhysicsState.HandleSetPositionCollisions` still returns `false`.
-Retail `CPhysicsObj::SetPositionInternal` (`0x00515330`) returns the real
-per-object report/tracking result. Establish the Runtime owner for that result
-and return it exactly. Do not restore the former environment/object-presence
-guess.
-
-Required tests:
-
- report/no-report objects;
- collided object set ordering and lifetime;
- reentrant deletion/reset;
- graphical/headless equality;
- no report state surviving GUID reuse.
-
-### Slice 4B2 prerequisite B — exact authored mover preparation
-
-Every production preparation must pass the full SetPosition request using:
-
- Setup's exact ordered authored spheres;
- exact scale, including valid zero/presence semantics;
- exact StepUp and StepDown heights;
- exact flags;
- exact cell-local frame and orientation;
- current position/vector/state authority versions.
-
-Do not reconstruct a cylinder from visual radius/height, clamp a positive
-scale, use the projectile mover as a generic object fallback, or pre-mutate
-`FullCellId`, `PhysicsBody`, `WorldEntity`, App buckets, or shadows.
-
-### Slice 4B2 prerequisite C — atomic local controller/body publication
-
-Implement the complete transaction described in the rejected-prototype note.
-Graphical and no-window controllers must end with the exact same Runtime body,
-but construction cannot expose or mutate canonical state before the validated
-atomic commit.
-
-Adversarial gates must include:
-
- nested construction;
- reentrant SetPosition;
- remote and projectile binding/update;
- deletion and same-GUID new incarnation;
- projection-owner replacement;
- object-clock epoch change;
- reset and disposal;
- commit and rollback after replacement;
- late graphical camera/shadow/host failure;
- late headless prepared-collision failure.
-
-### Slice 4B2 prerequisite D — presentation-only host projection
-
-Add one graphical and one headless `IRuntimePlacementObserver` using
-`GameRuntime.Placements`.
-
-Host receipt rules:
-
- `Withdraw`: remove render/spatial presentation, picking, radar, audio, and
-  targeting while retaining logical Runtime ownership.
- `Place`: project only the immutable Runtime-committed frame, then
-  acknowledge the exact token.
- `Discard`: discard the older projection revision, then acknowledge it.
- A host exception or unavailable backend does not roll Runtime back; retry
-  the same FIFO head.
-
-`LiveEntityRuntime.RebucketLiveEntity` must become presentation-only. Its
-current `CommitRebucket` call is a second spatial authority and must be removed
-as part of the same cutover.
-
-### Slice 4B2 prerequisite E — collision-prefix quiescence
-
-Before landblock collision demotion, removal, or replacement:
-
-1. quiesce the prefix;
-2. drain/ack the existing placement receipt prefix;
-3. call `RuntimeSetPositionState.ParkCollisionResidents`;
-4. commit/withdraw the collision generation atomically;
-5. wake only exact cell+generation residents.
-
-Cover `LandblockPhysicsPublisher.DemoteToTerrain`, `RemoveLandblock`,
-replacement commit, and the headless collision-retirement path. No partially
-observable collision generation is allowed.
-
-## Production route cutover
-
-Cut routes only after all prerequisites above are present. The canonical chain
-for every route is:
-
-```text
-wire acceptance
-  -> BeginAcceptedPlacement exact token
-  -> exact DAT/Setup preparation
-  -> Runtime SetPosition canonical commit or deferred residence
-  -> immutable host projection receipt
-  -> exact host acknowledgement
-```
-
-### 1. Initial login and CreateObject
-
-Current duplicate authority:
-
- `DatLiveEntityProjectionMaterializer.MaterializeProjection` immediately
-  positions/rebuckets the world entity.
- `PlayerModeController.BuildControllerAndCamera` builds its own body and runs
-  `Resolve`/`ResolvePlacement`.
- Headless performs its own initial resolve/placement/body construction.
-
-Required order:
-
-1. register identity cellless;
-2. begin initial/remote-create placement before hydration;
-3. load exact Setup mover;
-4. prepare the atomic Runtime controller/body relationship;
-5. submit canonical SetPosition;
-6. publish presentation only from `Place`;
-7. acknowledge, then enable player mode/simulation.
-
-Tests: outdoor/indoor login, unavailable destination then exact-generation
-wake, malformed or delayed Setup, one body identity, one enter-world clock
-reset, no early visible entity, graphical/headless identical snapshots.
-
-### 2. Local ForcePosition
-
-Delete the placement authority in `LocalForcePositionTransaction` and the
-direct `BlipPosition`/pre-commit acknowledgement in
-`LiveEntityNetworkUpdateController.OnPosition`.
-
-Required order: accept timestamp and preserve heading; begin
-`LocalAuthoritative`; canonical SetPosition; host `Place` acknowledgement;
-then send the outbound Position acknowledgement. A missing destination cell
-must not acknowledge ACE early.
-
-Tests: same/cross cell, preserved heading/velocity, missing-cell wake,
-reentrant newer Position, stale host ack, exactly one outbound ack.
-
-### 3. Portal transit and materialization
-
-Remove placement authority from `LocalPlayerTeleportPlacement.Place` and its
-direct resolve/controller/world-entity/rebucket/spatial mutations.
-
-Bind a Runtime portal-placement authority to the active
-`RuntimeWorldTransitState` reveal generation, teleport sequence, exact
-destination cell, and placement token. Readiness permits submission only.
-Materialization and simulation release happen only after canonical commit,
-host projection, and exact acknowledgement. Cancellation/replacement produces
-`Discard`; a stale generation/sequence/cell/token can never reveal.
-
-Tests: `/ls`, spell recall, ordinary portal, same-location revisit, missing
-destination, cancelled/replaced reveal, host throw/retry, no early world reveal
-or LoginComplete.
-
-### 4. Remote CreateObject and Position
-
-Delete `RemoteTeleportController`, `RemoteTeleportPlacement`, their pending
-dictionary/rollback/lost-cell ownership, and pre-placement
-`WorldEntity.SetPosition`/rebucket calls.
-
-Preserve retail `MoveOrTeleport` classification:
-
- fresh Teleport timestamp or cellless body: teleport hook then SetPosition;
- ordinary nearby grounded update: interpolation remains;
- distant update: stop interpolation then SetPosition.
-
-Accept the timestamp, begin the exact token before hydration/body/App changes,
-unparent first, run the retail teleport hook when required, submit the exact
-mover, project after Runtime commit, then re-arm constraints.
-
-Tests: visible/hidden/parented CreateObject, first Position, Teleport timestamp,
-near interpolation, >96 m far placement, unloaded indoor destination, racing
-velocity, delete/GUID reuse during host callback.
-
-### 5. Projectile authoritative create/corrections
-
-Remove authoritative placement from App `ProjectileController` and the direct
-SnapToCell/cell/shadow commit in `RuntimeProjectilePhysicsUpdater`.
-
-Use `ProjectileAuthoritative` with the same Runtime body and exact projectile
-Setup sphere for initial create and authoritative corrections. Preserve
-prediction/component/effect identity. Do not route ordinary per-quantum
-projectile integration through SetPosition.
-
-Tests: arrow, bolt, spell projectile, mid-flight correction, unloaded cell,
-landblock crossing, delete during ack, no duplicate body/projectile/effect.
-
-### 6. Drops and unparent-to-world
-
-`InventoryWorldDropProjectionController.TryRecoverUnknownPosition` may create
-the logical object, but it must enter the same canonical create-placement
-transaction. Do not expose a stale source position or replay create-time
-effects.
-
-Tests: whole item, split stack, new GUID, second drop position, attached child
-becoming a world root, unavailable destination, newer Position while waiting.
-
-### 7. Pickup, Parent, and Delete
-
-Runtime hooks already exist in `RuntimeEntityObjectLifetime`, but the route
-cutover must ensure pickup/parent/delete cancel the exact active
-placement/lost-cell family first and publish `Discard`/`Withdraw` before the
-later entity/inventory delta.
-
-Tests: pickup during preparation/deferred residence, parent during pending
-withdrawal, delete during host callback, GUID reuse, reset/disposal ownership
-convergence.
-
-### 8. Headless parity
-
-Delete the independent resolve/placement/direct SetPosition and Blip logic in
-`HeadlessSessionWorldProjection`. Headless must prepare/commit/ack through the
-same Runtime operations as graphical presentation. Portal completion also
-waits for the exact placement acknowledgement.
-
-Tests: byte-identical login, ForcePosition, portal, missing-cell wake,
-reconnect, and teardown snapshots.
-
-## AP-22 — retail-authored collision shapes
-
-After AP-1/AD-1 production cutover is stable:
-
- Make `ShadowShapeBuilder` the single Core authority for prepared Setup
-  primitives.
- Preserve authored cylinder order.
- If no cylinders exist, preserve authored spheres as spheres.
- Mixed data uses retail cylinder-first precedence.
- A truly shapeless Setup emits no world shadow.
- Remove `Setup.Radius/Height` collision synthesis, `Radius * 2` height guesses,
-  and sphere-to-cylinder coercion.
- Cut graphical static, headless static, and live-entity publication over
-  together.
- Do not alter transition dummy spheres, sticky/range radius, or projectile
-  mover shapes.
-
-Automated gates: raw/prepared parity, cylinder order, sphere-only, mixed,
-shapeless, scale, graphical/headless equality, representative installed DATs,
-and dropped/portal/sign/door behavior.
-
-## AD-10 — canonical remote slope projection
-
-After AP-22:
-
- Prove remote movement uses the full `ResolveWithTransition` sweep.
- Remove terrain-normal preprojection from `RemoteMotionCombiner`.
- Remove Runtime terrain-normal sampling calls and delete the sampler if no
-  longer used.
- Let `CTransition::adjust_offset` project against the retained actual contact
-  plane.
- Preserve interpolation queues, correction replacement, Hidden behavior,
-  network cadence, and graphical/headless parity.
-
-Tests must deliberately make terrain normals disagree with BSP/prop contact
-normals, then cover uphill/downhill motion, seams, stairs, jumping, landing,
-queue-empty/head-reached boundaries, and two-client observation.
-
-## Closeout gates
-
-Do not mark the campaign complete from narrow tests alone.
-
-Automated:
-
-```powershell
-dotnet build AcDream.slnx -c Release
-dotnet test AcDream.slnx -c Release --no-build --nologo
-```
-
-Also run every focused fixture named in the campaign plan: #273 tight gap,
-#271 stair side, #269 slope, #265 landing, #185 stairs, #137 sliding normal,
-#116 head collision, roof/cellar wedge, missing-cell, generation replacement,
-GUID reuse, graphical/headless parity, and allocation/quiescence gates.
-
-Connected/visual:
-
- login and portal arrival at outdoor, indoor, dungeon, stair-lip, and world
-  edge locations;
- repeated `/ls`, spell recall, ordinary portals, same-location revisit, and
-  reconnect;
- no early world reveal, outdoor demotion, floor snap, terrain-Z lift, or void;
- tight gaps, stairs, steep roofs, ledges, doors, crowds, shallow water, and
-  landblock seams;
- dropped objects, portals, signs, doors, and shapeless decorations;
- two-client uphill/downhill movement and sloped props;
- headless/graphical trace equality and graceful zero-residue teardown.
-
-Only then retire AP-1, AD-1, AP-22, and AD-10, update the architecture,
-divergence register, campaign/roadmap/milestones, research notes, durable
-memory, `CLAUDE.md`, and `AGENTS.md`, and record final rollback SHAs.
-
-## Review procedure for every remaining behavior commit
-
-1. Implement one bisectable mechanism and run focused tests.
-2. Run a retail-conformance reviewer against named retail symbols/addresses.
-3. Run an architecture/adversarial reviewer against reentrancy, stale
-   sequences, malformed data, GUID reuse, streaming replacement, host failure,
-   reset, and disposal.
-4. Fix every confirmed finding at its root cause.
-5. Re-run the same reviewers until clean.
-6. Run Release build plus the complete Release test suite.
-7. Update the divergence/docs in the same behavior commit.
-8. Stage exact paths only and commit.
-
-## Rollback points
-
-Newest first:
-
-```powershell
-git revert 270f5154   # dormant public placement receipt channel
-git revert 4c02ac42   # Runtime SetPosition/lost-cell residence owner
-git revert e84a388e   # pure Core retail SetPosition transaction
-```
-
-Earlier campaign commits are individually bisectable and listed in the
-completed sections above. Revert only the responsible mechanism; do not
-restore the rejected snapshot lease or revive legacy compensation elsewhere.
-
-## First action for the next agent
-
-1. Read this file completely.
-2. Read `docs/research/2026-07-31-canonical-set-position.md` and the AP-1/AD-1
-   rows in `docs/architecture/retail-divergence-register.md`.
-3. Confirm `HEAD` contains `270f5154` in the exact worktree above.
-4. Confirm only `AGENTS.md` has a real unrelated unstaged diff.
-5. Implement prerequisite A (real Runtime collision-report ownership) as its
-   own reviewed commit.
-6. Then design prerequisites B/C together so exact mover preparation and the
-   atomic controller/body transaction cannot create another partial ownership
-   state.

-# Runtime SetPosition collision-report ownership handoff - 2026-07-31
-
-## Purpose and exact stopping point
-
-This handoff records placement Slice 4B2 checkpoint 2: the isolated Runtime
-owner for retail SetPosition collision tracking and report-result semantics.
-The checkpoint intentionally stops before authored mover preparation, shared
-local-controller body publication, graphical/headless placement projection,
-collision-prefix quiescence, or any production SetPosition route cutover.
-
-Production behavior is therefore unchanged by this checkpoint. The new owner
-is populated only by the dormant `RuntimeSetPositionState` and focused tests.
-AP-1 and AD-1 remain narrowed/open; AP-22 and AD-10 remain open.
-
-## Exact workspace
-
- Worktree: `C:\Users\erikn\.codex\worktrees\af5e\acdream`
- Branch: `codex/port-claude-agents`
- Starting checkpoint: `ec627c13`
-  (`docs(physics): hand off remaining divergence campaign`)
- This handoff belongs to the same behavior commit as the implementation.
- No upstream is configured for this worktree branch.
- Remotes:
-  - `origin`: `https://git.snakedesert.se/erik/acdream.git`
-  - `github`: `git@github.com:eriknihlen/acdream.git`
-
-Continue in this worktree unless the user explicitly requests otherwise.
-`AGENTS.md` has an unrelated pre-existing content diff and must not be staged,
-restored, or rewritten as part of this checkpoint. Several other paths report
-line-ending/stat noise without a content diff; stage only the exact paths
-listed in the final commit.
-
-## Retail oracle
-
-The complete readable oracle is
-[`2026-07-31-runtime-set-position-collision-reporting.md`](2026-07-31-runtime-set-position-collision-reporting.md).
-The named-retail anchors are:
-
- `CPhysicsObj::report_object_collision_end` `0x00510A90`
- `CPhysicsObj::report_environment_collision` `0x00512FC0`
- `CPhysicsObj::report_object_collision` `0x00513060`
- `CPhysicsObj::track_object_collision` `0x00513F10`
- `CPhysicsObj::report_collision_start` `0x00513FD0`
- `CPhysicsObj::report_collision_end` `0x00514620`
- `CPhysicsObj::handle_all_collisions` `0x00514780`
- successful `CPhysicsObj::SetPositionInternal(CTransition const*)`
-  `0x00515330`
- `CPhysicsObj::leave_world` `0x005155A0`
- placement failure in `CPhysicsObj::SetPositionInternal` `0x00515BD0`
-
-The source is `docs/research/named-retail/acclient_2013_pseudo_c.txt`; the
-struct authority is `docs/research/named-retail/acclient.h`.
-
-## What this checkpoint implements
-
-`RuntimeCollisionReportingState` is the sole per-session owner of:
-
- one environment-collision latch per exact `RuntimeEntityKey`;
- one ordered object-contact table per exact owner incarnation;
- retained peer server GUID, touch time, and ethereal-at-touch state;
- static and `ReportAsEnvironment` routing;
- asymmetric `IgnoreCollisions` and reciprocal `ReportCollisions` eligibility;
- strict ordinary `age > 1.0` and ethereal `age > 0.0` expiry;
- force-end-before-callback mutation for reentrant safety;
- missing-peer self-only end reports without resolving a later GUID reuse;
- exact `Missile | AlignPath | PathClipped` clearing on the canonical record,
-  borrowed body, retained shadow state, and mutation version;
- a monotonic immutable report FIFO with observer-failure isolation;
- the retail callback-eligibility boolean used by failed placement to choose
-  `Collided` versus `NoValidPosition`;
- terminal ownership diagnostics and deterministic session/disposal cleanup.
-
-Successful dormant SetPosition commits contact, water/walkable and ground
-edges first, runs reporting next, applies physical response once, and then
-refloods the shadow. An intervening Vector or Movement update suppresses only
-the stale physical response; it does not erase collision tracking or reports.
-Failed placement always supplies retail's `previousContact = false` and
-`previousOnWalkable = false`, reports once, applies its one response pass, and
-maps the report result exactly.
-
-Hidden, teleport/withdrawal, deletion, session reset, and disposal use distinct
-lifetime edges. Leaving the world force-ends the departing owner's table but
-retains its environment latch and incoming peer records. Destruction then
-forgets only the departing owner state. Other owners retain exact-key contacts
-until their own expiry/force pass and can emit a missing-target end using the
-preserved server GUID. Hidden and session-clear paths force-end while the old
-report flags and bodies are still eligible, before state/reset teardown.
-
-## Architectural boundaries
-
- Runtime owns all canonical collision-report state and report-result logic.
- Core exposes only the exact successful SetPosition ordering seam and the
-  retained-shadow collision identity required by Runtime.
- App and Headless gain no report table, queue, heuristic, or production
-  placement consumer.
- Reports are presentation-free and keyed by exact Runtime identity.
- Network/update callbacks may re-enter, but every later mutation revalidates
-  current identity, body, and the relevant authority version.
- Physical-response velocity authority is deliberately separate from report
-  authority, matching retail's ordering without overwriting a newer vector.
-
-## Validation and independent review
-
-The saved final diff passed:
-
- combined focused Runtime collision-report and SetPosition tests: 76/76;
- complete Runtime project: 562/562;
- graphical/headless Runtime-physics ownership and dormancy guards: 4/4;
- focused Core SetPosition/contact/response ordering tests: 29/29;
- complete Core project: 4,224 passed / 1 intentional skip;
- from-source Release solution rebuild: 0 errors and 21 pre-existing test-
-  project nullable/analyzer warnings; this checkpoint introduces none;
- complete Release solution: 10,309 passed / 4 intentional skips;
- warmed steady-contact refresh: 0 managed bytes across 10,000 calls;
- warmed immediate dormant SetPosition commit: still below the existing
-  2,048-byte-per-operation ceiling, with no new captured-delegate cost;
- architecture/adversarial re-review: clean after fixing Hidden/session/delete
-  reentrancy, stale shadow-state authority, allocation churn, and batch cost;
- retail-conformance re-review: clean against every named address above.
-
-The final retail re-review found and closed two last ordering defects before
-sign-off: object collision now snapshots the mover's Missile bit before the
-source callback and, when that snapshot was set, unconditionally masks the
-current `Missile | AlignPath | PathClipped` bits afterward. Thus an ordinary
-callback-added Missile is retained when the mover was not previously a missile,
-but a callback which clears Missile and re-adds path bits cannot evade the
-pre-gated retail mask. Environment collision retains retail's post-callback
-current-Missile test. Successful SetPosition now
-publishes reports before installing the new stationary-fall counter, applies
-the physical response next, installs StationaryFall/Stop/Stuck transient bits
-after response, and only then refloods the shadow.
-
-The host guard reads both production source trees. It proves App and Headless
-borrow `GameRuntime.EntityObjects.Physics`, declare no second collision table
-or return heuristic, and still contain no placement-channel consumer. No
-connected/live gate is required for this dormant checkpoint because no
-production route can populate or publish the new report owner.
-
-## Exact implementation and test paths
-
-The behavior commit containing this handoff changes exactly these ten code and
-test paths:
-
- `src/AcDream.Core/Physics/PhysicsObjUpdate.cs`
- `src/AcDream.Core/Physics/ShadowObjectRegistry.cs`
- `src/AcDream.Runtime/Entities/RuntimeEntityDirectory.cs`
- `src/AcDream.Runtime/Entities/RuntimeEntityObjectLifetime.cs`
- `src/AcDream.Runtime/Entities/RuntimeEntityRecord.cs`
- `src/AcDream.Runtime/Physics/RuntimeCollisionReportingState.cs`
- `src/AcDream.Runtime/Physics/RuntimePhysicsState.cs`
- `src/AcDream.Runtime/Physics/RuntimeSetPositionState.cs`
- `tests/AcDream.Runtime.Tests/Physics/RuntimeCollisionReportingStateTests.cs`
- `tests/AcDream.App.Tests/Runtime/RuntimePhysicsOwnershipTests.cs`
-
-The same commit synchronizes the architecture, divergence register, canonical
-SetPosition research, roadmap, milestones, project memory, prior campaign
-handoff pointer, retail-oracle note, and this detailed handoff. `AGENTS.md` and
-the pre-existing line-ending/stat-noise paths are deliberately excluded.
-
-## Remaining work - required order
-
-### 1. Exact authored mover preparation - complete 2026-08-01
-
-The dormant preparation contract is implemented and independently reviewed.
-It binds the Runtime-owned accepted frame and exact Setup DID, preserves the
-ordered authored spheres and scale/step semantics, seals the returned command,
-and forces stale deferred residents through exact re-preparation without
-pre-mutating canonical state. See
-[`2026-08-01-runtime-set-position-authored-mover-preparation.md`](2026-08-01-runtime-set-position-authored-mover-preparation.md).
-
-### 2. Atomic local-controller/body publication - next
-
-Prepare off-canonical, then perform one Runtime-validated atomic transaction
-which publishes the exact same body to graphical and no-window controllers.
-Every body writer, remote/projectile binding, SetPosition operation, clock
-epoch, deletion, reset and disposal path must participate. Do not resurrect
-the rejected snapshot/rollback lease documented in the prior handoff.
-
-### 3. Presentation-only host projection
-
-Implement graphical and headless observers over the existing dormant placement
-receipt channel. Withdraw removes presentation/spatial consumers while
-retaining Runtime identity; Place projects only the immutable committed frame;
-Discard retires the older revision. Host failure retries the exact FIFO head
-and never rolls Runtime back.
-
-### 4. Collision-prefix quiescence and atomic route activation
-
-Park SetPosition residents before retiring their collision prefix, publish the
-complete replacement generation, wake exact matching residents, and cut every
-spawn/Position/portal/projectile/drop/pickup/parent/delete route over together.
-Only then may AP-1 and AD-1 retire.
-
-### 5. Remaining campaign slices
-
- Port retail-authored object collision shape precedence and retire AP-22.
- Remove remote terrain-normal preprojection and let the transition resolver
-  use the retained contact plane, retiring AD-10.
- Run the full automated and connected matrix, update all ledgers, and close
-  the remaining physics campaign only with direct evidence.
-
-## Rollback
-
-This checkpoint is one bisectable commit. Revert the commit containing this
-file to remove collision-report ownership without disturbing the earlier
-SetPosition residence and receipt-channel checkpoints. Do not revive the old
-collision-presence guess or the rejected body snapshot lease.
-
-Because a Git commit cannot embed its own final hash, resolve the exact
-checkpoint and revert command without ambiguity using:
-
-```powershell
-$checkpoint = git log -1 --format=%H -- `
-  docs/research/2026-07-31-runtime-set-position-collision-reporting-handoff.md
-git show --stat $checkpoint
-git revert $checkpoint
-```
-
-Earlier rollback points remain:
-
-```powershell
-git revert 270f5154   # dormant public placement receipt channel
-git revert 4c02ac42   # Runtime SetPosition/lost-cell residence owner
-git revert e84a388e   # pure Core retail SetPosition transaction
-```
-
-## Resume procedure
-
-1. Continue in
-   `C:\Users\erikn\.codex\worktrees\af5e\acdream` and verify
-   `git branch --show-current` reports `codex/port-claude-agents`.
-2. Resolve the exact checkpoint with the `git log` command above and confirm
-   it is the current `HEAD` before starting the next behavior slice.
-3. Read `AGENTS.md`, `docs/architecture/acdream-architecture.md`, this file,
-   the collision-report oracle, the canonical SetPosition research, and the
-   prior remaining-campaign handoff completely.
-4. Run `git status --short`. Preserve the unrelated `AGENTS.md` content diff
-   and every documented line-ending/stat-noise path. Never stage by blanket.
-5. Begin only **Exact authored mover preparation**, the first remaining item
-   above. Do not activate production routes, retire AP-1/AD-1, begin AP-22 or
-   AD-10, or resurrect the rejected body snapshot/rollback lease.
-6. Use exact-path staging and rerun the matching focused projects,
-   `dotnet build AcDream.slnx -c Release --nologo`, and
-   `dotnet test AcDream.slnx -c Release --no-build --nologo` before the next
-   reviewed checkpoint.

-# Runtime SetPosition collision-report ownership
-
-**Scope:** placement/streaming Slice 4B2 prerequisite A only. This closes the
-missing Runtime owner for retail collision tracking and the boolean returned by
-`CPhysicsObj::handle_all_collisions`. It does **not** activate any graphical or
-headless production SetPosition route.

-### Environment reporting
-
-```text
-report_environment_collision(meInContact):
-    reported = false
-    if !colliding_with_environment:
-        if self.ReportCollisions && self.weenie != null:
-            DoCollision(EnvCollisionProfile(self.velocity, meInContact))
-            reported = true
-        colliding_with_environment = true
-        if self.Missile:
-            self.state &= ~(Missile | AlignPath | PathClipped)
-    return reported
-```
-
-The latch is independent of callback eligibility. An object with no collision
-callback still latches its environment contact, and a repeated environment hit
-returns false. Retail has no environment-end callback. `leave_world` does not
-clear this latch; the next `handle_all_collisions` call re-arms it only after a
-non-environment frame.
-
-### Object reporting and tracking
-
-```text
-track_object_collision(other, meInContact):
-    if other.Static:
-        return report_environment_collision(meInContact)
-
-    record = { touched_time = PhysicsTimer.curr_time,
-               ethereal = other.Ethereal }
-    existed = collision_table.clobber(other.id, record)
-    if existed:
-        return false
-    return report_object_collision(other, meInContact)
-```
-
-The table insert/refresh precedes callbacks. Duplicate contacts refresh their
-time but never replay a start callback. DAT/static classification and physics
-state come from the exact shadow object which produced the collision; object-ID
-presence is not a valid substitute.
-
-`report_object_collision` first maps `ReportAsEnvironment` to the environment
-path. Otherwise:
-
- the mover reports only when the other object is not `IgnoreCollisions` and
-  the mover has `ReportCollisions` plus a weenie;
- a mover which had Missile set before the source callback unconditionally
-  masks its current `Missile | AlignPath | PathClipped` bits after striking a
-  non-ignored object, even when the callback cleared Missile but re-added path
-  bits; when pre-callback Missile was clear, callback-added Missile is retained;
- the reciprocal report occurs only when the other has `ReportCollisions`, the
-  mover is not `IgnoreCollisions`, and the other has a weenie;
- the return is true when at least one callback is attempted. It is never a
-  collision-presence boolean.
-
-### Expiry and end reporting
-
-`report_collision_end(force)` removes records before dispatching callbacks.
-This ordering is required for safe reentrancy.
-
-```text
-ordinary record: remove when age > 1.0, or force
-ethereal record:  remove when age > 0.0, or force
-```
-
-Equality remains alive. A still-resolvable non-`ReportAsEnvironment` peer may
-receive reciprocal collision-end callbacks. When the peer no longer resolves,
-the owner can still receive its self-only end using the stored retail object
-ID. A later incarnation must never satisfy the old contact record.
-
-### `handle_all_collisions` and SetPosition ordering
-
-```text
-handle_all_collisions(info, previousContact, previousOnWalkable):
-    reported = false
-    for other in info.collidedObjects, in encounter order:
-        reported |= track_object_collision(other, previousContact)
-    report_collision_end(force = false)
-
-    if environment latch is already set:
-        latch = info.collided_with_environment
-    else if info.collided_with_environment
-         || (!previousOnWalkable && self.OnWalkable):
-        reported |= report_environment_collision(previousContact)
-
-    apply retail collision velocity/stationary response
-    return reported
-```
-
-Successful `SetPositionInternal(CTransition const*)` commits the resolved
-cell/frame, Contact/WaterContact/OnWalkable state, and HitGround/LeaveGround
-edge before `handle_all_collisions`; it ignores the returned boolean and only
-then replaces/refloods shadows. Collision reports observe the old stationary-
-fall state; the new counter is installed before physical response, while the
-StationaryFall/Stop/Stuck transient bits are replaced after response and before
-shadow reflood. The placement failure path calls
-`handle_all_collisions(info, false, false)` and maps true to
-`SetPositionError::Collided` (`4`) and false to `NoValidPosition` (`2`).
-
-Consequently acdream must keep report/tracking separate from the physical
-response: failed placement runs both once, while successful Runtime commit
-runs reporting between the contact/ground commit and shadow reflood without
-double-applying velocity response.
-
-## Runtime ownership contract
-
-The implementation is presentation-free and belongs to the per-session
-`RuntimePhysicsState` graph. Its invariants are:
-
- owner and peer identities are exact `RuntimeEntityKey` values, not server
-  GUID or local ID alone;
- each tracked record retains the peer server GUID, touch time in the Runtime
-  simulation-clock domain, and ethereal-at-touch bit;
- collided IDs and authored/static ownership are admitted through the exact
-  retained `ShadowObjectRegistry` registration which produced the collision;
-  every dynamic Static/Ethereal/Ignore/ReportAsEnvironment decision then reads
-  the current canonical `PhysicsBody.State`, never a stale shadow snapshot;
- immutable reports preserve encounter order and dispatch through a retained,
-  reentrancy-safe FIFO;
- callback exceptions are isolated, while the retail report-result boolean is
-  determined by callback eligibility and does not depend on subscribers;
- every callback boundary revalidates the exact record/body/authority before
-  any later canonical mutation;
- force-end mutates the complete expired set before publishing ends; exact-key
-  admission guards prevent callback reentry from recreating a leaving owner,
-  and session teardown blocks the whole owner batch before its first callback;
- one source lifetime token covers a complete precollected end batch, so a
-  callback-accepted delete stops every later peer report even while teardown
-  sidecars remain resolvable;
- lifetime forget, session reset, and disposal cannot donate state to GUID
-  reuse;
- terminal ownership diagnostics include contact/report state and converge to
-  zero;
- graphical and no-window hosts borrow the same Runtime owner. No host owns a
-  second collision table or report-result heuristic.
-
-The warmed steady-contact refresh path allocates zero managed bytes. Expired
-contact storage is allocated lazily only after the first actual expiry, and
-session-batch teardown is linear in owner count.
-
-## Deliberately deferred
-
-The canonical SetPosition owner remains dormant in production. The following
-belong to later 4B2 commits and are not part of this checkpoint:
-
- exact ordered Setup spheres, authored scale and step-height preparation;
- the atomic shared local-controller body transaction;
- presentation-only rebucketing and placement-prefix quiescence;
- graphical/headless spawn, Position, portal, projectile, drop, pickup,
-  parent, and delete route cutover.
-
-AP-1 and AD-1 therefore remain open, narrowed only by removal of the
-collision-report prerequisite.

-# Runtime initial Create residence handoff - 2026-08-01
-
-> **Status:** this remains the `38fd4b8d` residence-foundation history. The
-> completed inbound-admission checkpoint and current continuation boundary are
-> recorded in
-> [`2026-08-01-runtime-initial-placement-admission-handoff.md`](2026-08-01-runtime-initial-placement-admission-handoff.md).
-
-## Purpose and exact stopping point
-
-Commit `38fd4b8dc952236d4b98518c67335026c7815656` adds the dormant Runtime
-transaction which retains an entity's initial authored CreateObject placement
-until canonical SetPosition succeeds and the ordered remainder of the Create
-packet can be adopted. It does not yet cut the production App/Headless Create
-route over, so AP-1 and AD-1 remain open.
-
-This is the deliberate clean handoff requested by the user. In plain terms,
-Runtime now has a tested holding area for a newly created world object while
-its exact collision placement is being resolved. The object cannot become
-half-visible, consume later position packets, or be silently replaced during
-that interval. The next model starts at the executor/cutover boundary; it does
-not need to repair or redesign this ownership transaction.
-
-Do not start production cutover from an earlier checkpoint. Do not call this
-campaign complete: AP-1, AD-1, AP-22, and AD-10 remain open.
-
-## Exact workspace and Git state
-
- Worktree: `C:\Users\erikn\.codex\worktrees\af5e\acdream`
- Branch: `codex/port-claude-agents`
- Code checkpoint: `38fd4b8dc952236d4b98518c67335026c7815656`
- Immediately preceding host-staging checkpoint: `74103f75`
- No push or merge is part of this stopping point.
-
-The worktree intentionally contains unrelated user changes/stat noise. Do not
-stage, restore, normalize, or rewrite these paths as part of the continuation:
-
- `AGENTS.md` (real unrelated content change);
- `src/AcDream.App/Input/PlayerModeController.cs`;
- `src/AcDream.App/Interaction/PlayerInteractionMovementSink.cs`;
- `src/AcDream.App/Rendering/LiveAnimationPresentationContext.cs`;
- `src/AcDream.Runtime/Physics/RuntimeRemotePhysicsUpdater.cs`;
- `tests/AcDream.Core.Tests/Physics/CellTransitTests.cs`;
- `tests/AcDream.Core.Tests/Physics/Issue133DungeonTeleportPrefixTests.cs`;
- `tools/A8CellAudit/A8CellAudit.csproj`.
-
-The paths after `AGENTS.md` currently have no content diff and are reported
-because of pre-existing line-ending/stat noise. Always stage exact paths;
-never use `git add -A`.
-
-## Placement checkpoint chain
-
-The current mechanism was built as bisectable commits. The directly relevant
-chain, oldest first, is:
-
- `e84a388e` - pure Core retail SetPosition transaction;
- `4c02ac42` - Runtime deferred/lost-cell residence owner;
- `270f5154` - dormant placement receipt channel;
- `237d1184` - retail SetPosition collision-report owner;
- `442cb8f9` - exact authored mover preparation;
- `22651c82` - dormant Runtime local physics publication;
- `99f867f0` - sealed dormant SetPosition evaluation;
- `5785a07b` - dormant SetPosition activation;
- `ef436678` - placement acknowledgement ownership;
- `74c9b155`, `378ca95a`, `f05ed5c3` - graphical/headless projection seams;
- `99bf1751`, `9b0f59bd` - collision-prefix quiescence and atomic replacement;
- `0fbc7a1f` - hidden-object SetPosition ownership correction;
- `3f800a4a` - authoritative route classification;
- `74103f75` - inert App materialization before Runtime placement;
- `38fd4b8d` - initial Create residence, continuation FIFO, and adoption.
-
-## Owned mechanism in `38fd4b8d`
-
-`RuntimeInitialCreateResidenceState` now owns, per exact entity incarnation:
-
- the accepted initial Create frame and exact SetPosition operation;
- a cellless logical entity while authored placement is pending;
- a monotonic immutable FIFO for fresher Position continuations;
- accepted timestamp, position, vector, rotation, placement, and wire payloads;
- completion/adoption tokens and a revision which reject stale observers;
- exact authority revalidation across generation, identity, Create, position,
-  placement, full-cell, deletion, reset, GUID reuse, and disposal;
- reentrant-safe cancellation at the lifetime commit boundary.
-
-The public legacy registration path is intentionally unchanged. Production
-behavior remains on the previous route until the continuation executor and
-all-host cutover land together.
-
-### Exact behavior now protected
-
- Initial/New Create admission is previewed without consuming timestamps;
-  Existing and Stale packets still use the established gates.
- No collision generation is guessed. An initial residence can exist only
-  after binding a real, nonzero generation.
- Fresh Parent wins over Position, matching the packet's relation priority.
- An absent or present-zero position cell remains cellless instead of being
-  fabricated as an outdoor placement.
- Later accepted Position packets append to one immutable ordered FIFO. They
-  cannot mutate the original placement operation or bypass it.
- A completed but not yet adopted transaction remains exclusive. A later
-  Position revises the retained batch and invalidates the old adoption token;
-  it cannot disappear between completion and acknowledgement.
- Placement acknowledgement uses exact identity, operation, generation,
-  position authority, Create integration, full-cell, and placement-commit
-  versions.
- Reset first detaches and clears ownership, then publishes cancellation, so a
-  reentrant observer cannot invalidate enumeration or resurrect an owner.
- Delete, replacement, pickup, parent, withdrawal, reset, and disposal return
-  cancellation receipts to the caller's safe publication boundary instead of
-  invoking observers before later canonical mutation.
- Malformed initial or continuation packets fail before timestamp or canonical
-  state consumption. A corrected packet with the same instance can recover.
-
-The FIFO stores raw accepted Position facts rather than prematurely choosing
-a final movement route. That is intentional: contact, animation state, the
-server-position option, and player distance must be sampled at the same point
-where retail makes the routing decision.
-

-
-## Retail order for the next slice
-
-The next slice must preserve `SmartBox::HandleCreateObject` at `0x00454C80`:
-
-1. visual description;
-2. exactly one of Parent, Position, or Pickup relation;
-3. Movement;
-4. State;
-5. Vector;
-6. Weenie description;
-7. final resident-cell validity cleanup.
-
-Position routing must also preserve these named-retail distinctions:
-
- a same-incarnation Create position is not equivalent to standalone F748;
- ForcePosition performs its own timestamp/parent/placement route;
- remote near-contact interpolates, remote far-contact stops interpolation and
-  performs SetPosition, and remote teleport invokes the teleport hook before
-  SetPosition;
- local teleport performs SetPosition, then the player-teleported hook, then
-  constrains to the authoritative frame and clears velocity;
- local ordinary Position constrains first and interpolates only when the
-  server-position option and contact gate permit it.
-
-Therefore every retained continuation must include its
-`RuntimeAcceptedPositionSource`, and executor-time inputs must pin HasAnims,
-UsePositionFromServer, contact, and distance before mutation. Parent/Pickup and
-the same-Create Movement -> State -> Vector order must be part of the same
-synchronous adoption transaction.
-
-The principal named-retail anchors are:
-
- `SmartBox::HandleCreateObject` `0x00454C80`;
- `CPhysicsObj::SetPositionInternal` `0x00515330`;
- `PhysicsDesc::UnPack` `0x0051DDD0`;
- `CPhysicsObj::set_description` `0x00514F40`.
-
-Use `docs/research/named-retail/acclient_2013_pseudo_c.txt` first and the older
-Ghidra chunks only as a fallback.
-
-## Validation and reviews
-
-The implementation agent and reviewers reported:
-
- focused initial-residence and classifier tests: 79/79;
- complete Runtime tests: 819/819;
- Runtime Release build: zero warnings and errors;
- focused Core timestamp tests: 31/31;
- retail-conformance review: clean;
- architecture/adversarial review: clean;
- `git diff --check`: clean.
-
-Primary-agent final gates after the behavior commit:
-
- complete Release solution build: succeeded, 0 errors;
- complete Release solution tests: 10,612 passed / 4 intentional skips;
- App: 4,027 passed / 3 skips;
- Core: 4,242 passed / 1 skip;
- Runtime: 819 passed;
- Core.Net: 762 passed;
- UI abstractions: 543 passed;
- Headless: 76 passed;
- Content: 124 passed;
- Bake: 15 passed;
- CLI: 4 passed.
-
-The build reports 21 pre-existing test-project nullable/analyzer warnings. The
-checkpoint introduces no build errors or new production warning.
-
-Both independent reviews initially found real edge cases and the final code
-includes their root-cause fixes:
-
- completed-but-unadopted Position packets could bypass the FIFO;
- cancellation callbacks could re-enter before the caller's canonical mutation;
- reset could enumerate live dictionaries while a callback mutated them;
- adoption did not initially validate every spatial/authority version.
-
-Final retail-conformance and architecture/adversarial rereviews both passed.
-No connected visual gate was required because the new API is dormant and no
-production App or Headless route calls it yet.
-
-## Production routes intentionally unchanged
-
-This is the key handoff boundary. At this checkpoint:
-
- graphical Create still flows through
-  `LiveEntityHydrationController.OnCreateCore`,
-  `LiveEntityRuntime.RegisterLiveEntity`, and legacy `RegisterEntity`;
- graphical materialization still defaults to `LegacyImmediate` rather than
-  the new `AwaitRuntimePlacement` residence;
- graphical Position still performs its existing world-position, rebucket,
-  projectile, remote-motion, and shadow work;
- headless Create still uses `RuntimeLiveEntitySessionController.OnSpawned`,
-  `HeadlessSessionWorldProjection.ProjectSpawn`, and its independent initial
-  resolve/body construction;
- headless Position still uses its existing projection path;
- the new Runtime initial-residence API is reached by focused tests only.
-
-Existing host adapters already observe Runtime placement receipts. Do not add
-another observer architecture or a second GUID map.
-
-## Next implementation boundary
-
-Implement one Runtime continuation executor and exact ordered Create tail,
-then route graphical and no-window registration through it without a mirror.
-The executor must be synchronous or retry-idempotent around adoption revision;
-failure must leave the exact FIFO head retryable. Only after both production
-hosts and every Create/Position/ForcePosition/parent/pickup route use the same
-owner may AP-1 and AD-1 retire.
-
-### Required order for the next model
-
-1. Add `RuntimeAcceptedPositionSource` to every retained continuation. A
-   same-incarnation Create position and standalone F748 are not interchangeable.
-2. Implement one Runtime-owned synchronous continuation executor. Capture
-   `UsePositionFromServer`, animation/contact state, and player distance at the
-   retail-equivalent decision point.
-3. Execute initial placement once, consume its exact host acknowledgement,
-   then drain the continuation FIFO in order with retail's hook ordering.
-4. Serialize one Create packet as relation
-   (Parent/Position/Pickup), Movement, State, Vector, WeenieDesc, cleanup.
-5. Keep every side effect exactly-once. If execution can yield, make adoption
-   revision/idempotence explicit so retry cannot replay hooks or position sends.
-6. Switch graphical and headless registration together to the same Runtime
-   owner. Hosts may project immutable results only; they may not resolve a
-   second placement or create another body.
-7. Route later Create, Position, ForcePosition, teleport, parent, pickup,
-   withdrawal, delete, remote, projectile, and dropped-item edges through the
-   same owner before deleting legacy paths.
-8. Run focused tests, full Release build/tests, exact lifecycle/reconnect and
-   nine-stop connected gates, then perform the user visual matrix. Only then
-   retire AP-1 and AD-1.
-
-Do not begin AP-22 or AD-10 until the production placement cutover is green.
-
-### Subsequent independent slices
-
- **AP-22:** make `ShadowShapeBuilder` the only prepared Setup-shape authority;
-  preserve authored cylinder order, use spheres only when cylinders are absent,
-  allow truly shapeless Setups, and remove radius/height synthesis and sphere-
-  to-cylinder coercion across graphical/headless/live publication.
- **AD-10:** remove terrain-normal preprojection from remote motion. Let the
-  canonical transition resolver project against the actual retained contact
-  plane, with tests where terrain and BSP/prop normals deliberately differ.
- Run the final connected matrix, synchronize ledgers/docs, and only then close
-  the remaining physics-divergence campaign.
-
-## Rollback
-
-Revert the behavior checkpoint without disturbing the earlier placement
-foundation:
-
-```powershell
-git revert 38fd4b8dc952236d4b98518c67335026c7815656
-```
-
-The documentation checkpoint containing this file is a separate commit and
-can be reverted independently if only the handoff text needs correction.
-
-## Resume checklist
-
-1. Continue in the exact worktree and branch recorded above.
-2. Confirm `git rev-parse HEAD` includes both the behavior and documentation
-   checkpoint commits.
-3. Read this file, `docs/architecture/acdream-architecture.md`,
-   `docs/research/2026-07-31-canonical-set-position.md`, and
-   `docs/research/2026-07-31-runtime-set-position-collision-reporting-handoff.md`.
-4. Run `git status --short` and preserve every unrelated path listed above.
-5. Re-run the focused 79-test residence/classifier gate before modifying the
-   transaction.
-6. Begin only the continuation executor and ordered Create tail. Do not start
-   AP-22/AD-10 or vendor work in the same commit.

-# Runtime initial-placement admission handoff - 2026-08-01
-
-> **Status:** this remains the `30012361` admission-checkpoint history. The
-> continuation executor this file scoped as "the next implementation
-> boundary" is complete at `5db3de3c`; the current boundary (production
-> cutover) is recorded in
-> [`2026-08-02-runtime-continuation-executor-handoff.md`](2026-08-02-runtime-continuation-executor-handoff.md).
-
-## Purpose and exact stopping point
-
-Behavior commit `30012361e12222e8271b1531574257ba910c77cb`
-completes the bounded Runtime admission checkpoint requested by the user.
-While an entity's first authored placement is waiting, every later accepted
-same-incarnation update is preserved in exact arrival order without changing
-or displaying the entity early.
-
-In plain terms, Runtime now has a sealed mailbox behind the pending initial
-placement. Network sequence checks still decide which messages are fresh, but
-accepted messages wait in that mailbox. The visible/canonical entity remains
-at its original frozen Create state until a later executor is authorized to
-apply the mailbox.
-
-This checkpoint deliberately does **not** implement that executor, switch the
-graphical or headless production routes, begin AP-22 authored shape work, or
-begin AD-10 remote slope projection. AP-1 and AD-1 therefore remain open.
-
-This file supersedes the admission-status portions of
-`2026-08-01-runtime-initial-create-residence-handoff.md`; that earlier file
-remains the foundation history for commit `38fd4b8d`.

-
-## What `30012361` owns
-
-### One exact pending owner
-
-`RuntimeInitialCreateResidenceState` owns one transaction per exact
-`RuntimeEntityKey`, not per server GUID alone. It retains:
-
- the deep-frozen initial Create packet and placement operation;
- the exact residence token, generation, placement authority, and revision;
- a monotonic sequence for accepted continuations;
- one immutable, mixed-kind FIFO in original arrival order;
- completion/adoption and teardown receipts.
-
-The accepted continuation kinds are:
-
-1. same-incarnation Create;
-2. ObjDesc;
-3. Parent;
-4. Pickup;
-5. Position;
-6. Movement;
-7. State;
-8. Vector.
-
-There is no coalescing, sorting by message type, or replacement of an earlier
-accepted FIFO item by a later one.
-
-### Frozen public state
-
-While the initial residence is pending:
-
- retail timestamp gates advance for accepted updates;
- `RuntimeEntityRecord.Snapshot` remains unchanged;
- the public accepted-snapshot view remains unchanged;
- no entity/object event is published;
- no projection acknowledgement callback runs;
- parent commitment, world placement, rendering, radar, picking, physics,
-  audio, and other presentation remain unchanged;
- every accepted payload is retained as an immutable typed action.
-
-This is intentional gate-only acceptance. It is not an alternative canonical
-snapshot and must not grow into one.
-
-### Immutable payload boundary
-
-`RuntimeInitialCreateAdmissionFreezer` copies every parser-owned mutable
-collection that can outlive packet dispatch:
-
- EntitySpawn animation-part, texture, and sub-palette arrays;
- ObjDesc model arrays;
- motion command lists;
- Physics Movement raw bytes and motion commands;
- Physics child attachments.
-
-Same-incarnation Create is retained as one atomic envelope. Its actions retain
-retail's packet-tail order:
-
-1. AP-119 pre-tail description adaptation;
-2. ObjDesc;
-3. exactly one of Parent, Position, or Pickup;
-4. Movement;
-5. State;
-6. Vector;
-7. Weenie description;
-8. resident-cell cleanup.
-
-### Position facts remain raw
-
-A deferred Position retains the typed packet plus the timestamp disposition
-and accepted gate facts. It does not prematurely choose interpolation,
-teleport hooks, or final movement behavior. The new explicit
-`RuntimePositionConstrainPhase` distinguishes retail's local ordinary
-constrain-before route from remote/teleport constrain-after routes, but the
-future executor must still sample the required live inputs at the retail
-decision point.
-
-No selected UI target, presentation state, or host-specific route is stored in
-the admission owner.
-
-## Missing-parent behavior
-
-Named retail resolves a nonzero parent before child object lookup and child
-timestamp admission. Runtime now follows that order:
-
- a child Create whose parent is not addressable is stored as the complete raw
-  frozen Create packet;
- no child entity record, accepted snapshot, timestamp gate, local ID, event,
-  or residence lease exists yet;
- the queue is keyed by parent GUID but each entry also has a monotonic
-  `AdmissionId` which is never reset, preventing reset/reconnect ABA reuse;
- a later parent Create may consume only the exact admission token it peeked;
- deleting or replacing a still-missing parent does not discard its queued
-  child Create, matching retail's GUID-keyed placeholder behavior;
- an exact child Delete removes an equal/older deferred child generation even
-  if no child timestamp gate exists;
- generation cleanup preserves an equal or newer deferred child Create and
-  discards only older ownership.
-
-Raw missing-parent replay and actual child creation belong to the future
-continuation executor/cutover. They are not performed by this checkpoint.
-
-## Malformed and saturation behavior
-
-All structural and capacity checks run before consuming a timestamp gate.
-
- Non-finite Vector and Position payloads are rejected without sequence
-  consumption.
- A full/saturated continuation owner fails before gate acceptance; there is
-  no fallback to ordinary immediate mutation.
- Flattened EntitySpawn projections must exactly agree with the embedded
-  PhysicsDesc for identity, Position, relevant timestamps, parent, and
-  placement.
- When PhysicsDesc is absent, every flattened PhysicsDesc projection must also
-  be absent or zero: Position, Setup, Motion, PhysicsState, scale, friction,
-  elasticity, timestamps, parent, and placement.
- Instance sequence zero remains legal and is covered on the active pending
-  FIFO path.
-
-The last rule prevents synthetic or corrupt packets from creating two
-contradictory placement authorities even though the production parser normally
-constructs those projections from one source.
-
-## Lifetime and failure guarantees
-
- Delete cancels the matching residence and its FIFO before the exact entity
-  can be reused.
- New incarnation/GUID reuse cannot observe or adopt an older incarnation's
-  FIFO.
- Session reset/reconnect clears active residence, completed-unadopted batches,
-  deferred raw creates, accepted timestamp ownership, and operation state.
- Reentrant teardown callbacks cannot resurrect the detached owner.
- Completion/adoption revisions cannot wrap into a valid stale token.
- Parent raw-admission IDs cannot wrap or reset into an ABA match.
- Every ownership ledger converges to zero on reset/disposal.
-
-## Named-retail oracle
-
-The behavior and reviews used these named-retail anchors:
-
- `SmartBox::HandleCreateObject` `0x00454C80` - Create packet ordering and
-  missing-parent precondition;
- `SmartBox::ProcessObjectNetBlobs` `0x00454B20` - queued packet replay order;
- `SmartBox::HandleReceivedPosition` `0x00453FD0` - standalone Position route;
- `SmartBox::HandleDeleteObject` `0x00451EA0` - GUID-keyed delete behavior;
- `ACCObjectMaint::CreateObject` `0x00558870` - logical object creation;
- `CPhysicsObj::set_description` `0x00514F40` - PhysicsDesc application order;
- `CPhysicsObj::SetPositionInternal` `0x00515330` - canonical placement.

-## Automated evidence
-
-Final primary-agent gates on the exact behavior diff:
-
- focused initial-residence/classifier tests: **89 passed, 0 failed**;
- complete Runtime tests: **829 passed, 0 failed**;
- complete Release build: **0 warnings, 0 errors**;
- complete Release solution: **10,622 passed, 4 intentional skips**;
- `git diff --check`: clean.
-
-Per-project final solution totals:
-
- App: 4,027 passed / 3 skipped;
- Bake: 15 passed;
- CLI: 4 passed;
- Content: 124 passed;
- Core.Net: 762 passed;
- Core: 4,242 passed / 1 skipped;
- Headless: 76 passed;
- Runtime: 829 passed;
- UI abstractions: 543 passed.
-
-Independent final results:
-
- retail-conformance reviewer: **PASS**;
- architecture/adversarial reviewer: **PASS**.
-
-The reviews explicitly checked exact retail order, gate-only frozen state,
-missing-parent placeholder lifetime, zero instance, delete/reset/GUID reuse,
-deep freezing, malformed duplicated projections, capacity preflight,
-reentrancy, and the absence of executor/cutover work.
-
-No connected visual gate is required for this checkpoint because production
-graphical and headless routes remain unchanged and the new owner is exercised
-only through deterministic Runtime tests.
-
-## Deliberately unchanged production routes
-
-At this checkpoint:
-
- graphical Create/Position still use the existing App route;
- headless Create/Position still use the existing no-window projection route;
- no host drains `RuntimeInitialCreateResidenceState.Continuations`;
- no raw missing-parent child Create is replayed;
- no new gameplay/presentation callback is emitted;
- no AP-1 or AD-1 divergence row is retired;
- AP-22 and AD-10 are untouched.
-
-Do not mistake the stored FIFO for completed game behavior. The clean next
-boundary is the executor that applies it.
-
-## Next implementation boundary
-
-Implement only the Runtime continuation executor and retail Create tail.
-
-The executor must:
-
-1. consume the exact initial placement acknowledgement once;
-2. capture executor-time inputs at the retail decision point;
-3. apply the initial Create tail in retail order;
-4. drain mixed continuations strictly by retained sequence;
-5. preserve same-Create atomicity;
-6. keep the FIFO head retryable if an external host receipt is temporarily
-   unavailable;
-7. make every hook, timestamp, placement, and event side effect exactly once;
-8. consume a raw missing-parent Create only through its exact `AdmissionId`;
-9. abandon safely on delete, reset, replacement, or generation mismatch;
-10. produce host-independent immutable results rather than calling App or
-    headless presentation directly.
-
-Do not combine the executor with graphical/headless cutover. After the
-executor is independently green, the following checkpoint may switch every
-Create, Position, ForcePosition, Parent, Pickup, withdrawal, remote,
-projectile, dropped-item, and teardown route across both hosts together.
-
-Only after executor plus all-host cutover and connected gates pass may AP-1
-and AD-1 retire. AP-22 and AD-10 remain later independent slices.
-
-## Rollback
-
-Revert this behavior checkpoint without disturbing the prior residence
-foundation:
-
-```powershell
-git revert 30012361e12222e8271b1531574257ba910c77cb
-```
-
-The documentation checkpoint containing this file is separate and may be
-reverted independently if only the handoff text needs correction.
-
-## Resume checklist
-
-1. Open the exact worktree and branch above.
-2. Confirm `git log -3 --oneline` contains behavior `30012361` and the
-   documentation commit containing this file.
-3. Preserve every unrelated dirty path listed above.
-4. Read this file, `docs/architecture/acdream-architecture.md`,
-   `docs/research/2026-08-01-runtime-initial-create-residence-handoff.md`, and
-   `docs/research/2026-07-31-canonical-set-position.md`.
-5. Re-run the focused 89-test gate before changing admission/execution code.
-6. Begin only the continuation executor. Do not begin production cutover,
-   AP-22, AD-10, or vendor work in the same checkpoint.

-# Runtime local-player physics publication - 2026-08-01
-
-## Scope
-
-This is placement Slice 4B2 checkpoints 4-6. It adds the dormant,
-presentation-independent transaction which prepares and assigns ownership of
-one local-player `PhysicsBody` and `PlayerMovementController`, retains an exact
-post-ownership evaluation lease, and commits the canonical Runtime SetPosition
-activation in retail order. No App or Headless production route invokes this
-transaction yet, so graphical and no-window game behavior is unchanged and
-AP-1/AD-1 remain open until their hosts cut over.
-
-Checkpoint 6 consumes the prepared placement operation only after the exact
-body/controller/identity/collision envelope is current. It publishes FullCell,
-world residence, host, shadow, workset, object-clock, and ordered Place state
-from that same Runtime-owned dormant body. There is no second body, mirrored
-gameplay owner, rollback mutation, or presentation callback inside the
-canonical tail.
-
-## Ownership contract
-
-`RuntimeLocalPlayerPhysicsPublicationState` is the sole owner of unpublished
-local-player body/controller candidates. Each candidate is bound to a token
-containing:
-
- The exact `RuntimeEntityKey` and authored SetPosition placement token.
- A monotonic publication ID.
- The nonzero canonical local-player server GUID and exact identity revision.
- The record's physics-body and object-clock ownership epochs.
- The movement state's controller ownership epoch.
- The entity directory's session-lifetime authority.
-
-Preparation constructs a private controller, body, and object clock. It applies
-the exact authored cell frame, orientation, Setup sphere list, scale, step
-heights, and accepted final physics state without mutating the canonical entity,
-shared object clock, engine/worksets, shadow registry, FullCell, host state, or
-presentation. The candidate remains explicitly out of world and inactive. No
-method exposes its controller, body, clock, or another mutable reference while
-it is owned by the publication transaction.
-
-This checkpoint accepts only a pristine initial graph: no canonical body,
-movement controller, physics host, remote motion, projectile, acquisition or
-binding operation, or remote-placement contract may exist. It cannot replace or
-upgrade a live graph. The local-player identity must be live, nonzero, and name
-the same server GUID as the exact entity incarnation.
-
-Unpublished candidates and ownership-committed dormant controllers reject live
-movement operations: update, public SetPosition, blip, outbound-position
-capture, movement/position send tracking, and shared-engine position commit.
-Only the checkpoint-6 activation transaction may promote `RuntimeOwnedDormant`
-to `RuntimePublished`; preparation and evaluation never invoke that transition.
-Once a
-Runtime-owned dormant or published controller is replaced, reset, or disposed,
-its terminal retirement state rejects the same operations plus
-body/configuration mutation and manager acquisition. Publicly constructed
-legacy controllers keep their existing standalone behavior.
-
-## Failure-atomic commit
-
-Commit revalidates every authority after preparation:
-
- The entity record is the current incarnation and is not accepted for delete.
- The local-player identity still has the token's exact GUID and revision and
-  has not been disposed.
- The exact authored SetPosition operation and sealed command remain current.
- Session, body, object-clock, and controller ownership epochs still match.
- The body/controller/host/remote/projectile graph remains completely pristine,
-  with no acquisition, binding, or remote-placement operation in progress.
-
-Only after validation completes does the callback-free update-thread tail:
-
-1. Rebind the candidate controller from its private clock to the record's exact
-   canonical object clock and mark it Runtime-owned but dormant.
-2. Store the candidate's exact body on the canonical record, advancing the
-   physics ownership epoch once.
-3. Store the same controller in `RuntimeLocalPlayerMovementState`, advancing the
-   controller ownership epoch once.
-
-The dormant controller rejects every live/configuration operation after these
-stores; ownership commit alone cannot tick physics, mutate the canonical clock,
-or publish an outbound frame. These stores allocate no new gameplay owner,
-invoke no host or presentation callback, and cannot replay an older
-incarnation. Replacing SetPosition,
-changing any accepted physics authority, binding remote/projectile state,
-replacing body/clock/controller ownership, delete plus GUID reuse, reset, or
-disposal causes the token to reject. An identity switch away and back also
-rejects because its revision changed. A rejected or superseded candidate is
-discarded and cannot perform a later live operation. Reset and disposal converge
-the publication ledger to zero candidates.
-
-Repeated stores of the same body/controller do not advance their epochs; real
-bind, replacement, and unbind edges do. This makes ABA-shaped reference changes
-observable even if a later value happens to equal an earlier reference.
-
-## Dormant SetPosition evaluation lease
-
-Ownership commit now returns one private activation token captured only after
-the canonical body and controller stores. It binds the exact entity key,
-authored placement token and sealed command, local identity GUID/revision,
-session lifetime, and the post-store physics-body, object-clock, and controller
-ownership epochs. The owner retains the same record, body, controller, and
-command behind that token; no caller can substitute an equivalent-looking
-body or rebuild the mover.
-
-`EvaluateActivation` revalidates that complete lease and calls Core
-`PhysicsEngine.SetPosition` synchronously with an immutable request. Core's
-transaction is pure: it returns committed, deferred-cell, or rejected
-placement data without writing the canonical body, FullCell, clock, spatial
-worksets, shadows, collision-report owners, host, operation stage, or Place
-projection. A missing cell therefore leaves the exact body dormant and the
-authored operation retryable. During evaluation, a valid result likewise
-remains only an immutable receipt; checkpoint 6's separate commit API consumes
-that receipt only after revalidating the complete activation envelope.
-
-Each evaluation carries an append-only, stable-order union of every cell read
-by the complete Core transaction: the AdjustPosition seed and adjusted cell,
-visible-child probes (including rejected lateral siblings), rejected
-portal/building containment probes, transition/compass retries, and every
-normal or scatter attempt. Rejected probes enter only the authority union and
-never the final successful shadow/CrossCell footprint. Scatter keeps that union
-in retained scratch and materializes its
-immutable receipt exactly once after the final attempt, avoiding quadratic
-copy/allocation growth at the 64-attempt retail ceiling. The final
-`CrossCellIds` remains the successful placement's authored
-shadow footprint; failed scatter probes cannot leak into that commit payload.
-Runtime seals every distinct queried landblock against the exact collision
-generation, the global collision-world authority, and the dynamic-shadow
-mutation revision. An active replacement admission rejects evaluation even
-before it commits, while begin/cancel, a re-entrant generation commit, or any
-owner insert/remove/move/state/suspend/reflood mutation invalidates an older
-receipt.
-
-Entry restrictions also consult the live `ClientObjectTable` for the resolved
-house object, owner and complete restriction record, plus the mover's monarch.
-The receipt therefore seals the exact object-table reference, the engine's
-monotonic binding epoch, and the table's synchronous mutation revision. Object
-creation/removal, owner-property, guest-list, or mover-monarch updates invalidate
-the receipt; a null/fresh replacement and an equal-revision A-B-A binding cycle
-cannot resurrect it. Retained `ClientObject` owner, monarch, and restriction
-setters synchronously advance every exact owning table even when callers mutate
-the object directly rather than re-submit it through `AddOrUpdate`. Replacement,
-removal, and clear detach that observer exactly, and every
-`HouseRestrictionRecord` freezes a defensive snapshot of its input guest map so
-no caller-owned dictionary or mutable downcast can alter entry authority behind
-the revision.
-
-`IsEvaluationCurrent` accepts only the newest receipt for the exact activation
-lease and rejects it after a position/vector/state/object-description/Create
-authority change, identity revision, body/controller replacement, session or
-incarnation change, or any sealed collision/shadow authority change.
-Re-evaluation supersedes the older receipt without mutating world state.
-Re-entrant reset or delete-plus-GUID-reuse during Core evaluation immediately
-retires the invalid lease instead of leaving an orphaned dormant graph. An
-existing activation lease also blocks candidate preparation even if an
-external owner has already cleared the body/controller references; explicit
-discard is required before a new candidate can be prepared. Reset and disposal
-retire the lease, body, and dormant controller and include the pending
-activation in the ownership convergence ledger.
-
-## Canonical activation and retail ordering
-
-The implementation follows the named-retail chain rather than treating
-SetPosition as a single opaque callback:
-
- `CPhysicsObj::SetPosition` at `0x005160C0` owns the outer placement call.
- The internal wrapper at `0x00515BD0` evaluates residence and collision.
- `CPhysicsObj::SetPositionInternal(CTransition*)` at `0x00515330` commits the
-  accepted frame/contact prefix and later shadow/cell state.
- `CPhysicsObj::enter_world` at `0x00516170` is the final live edge.
- `CPhysicsObj::leave_world` at `0x005155A0` is the canonical retirement edge.
-
-Runtime splits that chain into a prepared, callback-free transaction and an
-ordered notification suffix:
-
-1. Install the accepted frame and contact prefix on the still-dormant body and
-   perform the first acceleration calculation.
-2. Open one narrow dormant ground phase and invoke `HitGround` or
-   `LeaveGround`. Movement reapplication may call retail `set_velocity`, but
-   the phase closes with `Active=false`; the body is still out of world, has no
-   host/spatial membership, and its object clock is inactive.
-3. Synchronize accepted State and Vector authorities, run the post-ground
-   acceleration/sliding phase, and dispatch the already-installed collision
-   batch.
-4. Revalidate the complete ownership/collision envelope. Accepted State and
-   Vector updates are synchronized; Position, ObjDesc, Create, Setup,
-   incarnation, identity, collision-generation, body, controller, host, or
-   session displacement aborts the old transaction.
-5. Apply velocity-current physical response and stationary bits, prepare the
-   final shadow mutation and Place receipt, then perform the callback-free
-   FullCell/body/host/controller/spatial/object-clock tail.
-6. Dispatch exact shadow notifications and the ordered Place projection only
-   after the complete live graph is visible.
-
-Collision and shadow mutations use explicit prepare/apply/dispatch receipts.
-Receipt dispatch is exact-once and owner-local, so reverse-order receipts for
-different owners remain valid while a superseding mutation of the same owner
-stops the stale suffix. Collision owner states carry the exact SetPosition
-batch ID. Reentrant Position or newer-batch replacement suppresses remaining
-reciprocal/environment callbacks, and abort cleanup force-ends/removes only the
-still-exact old batch, including reverse rows and the environment latch. The
-combined Runtime physics ownership ledger includes pending collision and
-shadow SetPosition receipts; teardown cannot report convergence while either
-receipt remains.
-
-Candidate construction applies the accepted `PhysicsDesc` values in retail
-`CPhysicsObj::set_description` order before sealing ownership: final state,
-friction, clamped elasticity, `set_velocity` (including the 50-unit clamp),
-and angular velocity. Network acceleration remains parse-only because retail
-recalculates it from the final physics state. This initial vector bootstrap is
-required even when the SetPosition receipt's source Vector authority is still
-current; the later refresh intentionally skips in that case. Collision
-callbacks may advance State/Vector authority without invalidating the
-immutable geometry/identity envelope, and a changed Vector authority refreshes
-the dormant body through the same `set_velocity` path before physical response.
-
-A deferred-cell commit atomically suspends an authored shadow registration and
-consumes its notification receipt. Explicit publication discard cancels the
-exact SetPosition lease and body/controller ownership, while the suspended
-registration remains owned by the live entity/shadow registry and is reusable
-by a later activation. A deterministic discard -> generation-ready -> new
-activation gate proves the same registration restores without stale rows or a
-pending receipt. Entity/lifetime teardown remains the terminal owner of that
-suspended registration.
-
-## Gates
-
- Candidate privacy and live-operation rejection.
- Pristine-only admission for body, controller, host, remote/projectile,
-  acquisition/binding, and remote-placement ownership.
- Exact local-player identity, identity-switch, and disposed-identity rejection.
- Exact same-body ownership in entity record and dormant movement controller.
- Initial PhysicsDesc velocity, angular velocity, friction, and elasticity
-  bootstrap, including activation with the retail 50-unit velocity clamp.
- Dormant rejection after ownership commit plus the controller-level
-  `dormant -> activated -> live` lifecycle contract exercised by checkpoint 6.
- No mutation of SetPosition, FullCell, spatial roots, host projections,
-  shadows, worksets, world residence, or presentation during preparation or
-  evaluation; the separately gated activation commit owns those mutations.
- Replacement by position, vector, final physics state, object description,
-  CreateObject, remote/projectile/body/clock/controller ownership, and explicit
-  placement cancellation.
- Delete plus same-GUID reincarnation.
- Candidate replacement, reset, disposal, and ownership convergence.
- Publication/activation sequence exhaustion is preflighted before candidate
-  allocation or replacement, leaving no private or canonical owner behind.
- Shadow-registry reset invalidates even a prepared, unapplied shapeless
-  transaction which owns no logical rows or pending dispatch receipt.
- Pure committed/deferred/rejected SetPosition evaluation with bit-exact
-  body-state snapshots and no canonical, collision-report, projection,
-  clock, FullCell, host, shadow, workset, or operation-stage mutation.
- Complete stable-order queried-cell capture across AdjustPosition,
-  visible-child lookup, normal/scatter retries, map-edge/deferred, rejected,
-  committed, and defensive NoCell outcomes. Scatter deliberately retains
-  retail's RNG consumption; only its authority footprint and commit payload
-  are deterministic for a fixed draw sequence.
- Newest-receipt selection, active-admission rejection, collision-generation
-  replacement, re-entrant begin/cancel and commit invalidation, plus dynamic
-  shadow insert/move/state/suspend/remove invalidation.
- Exact object-table reference/revision/binding authority, including
-  post-evaluation and re-entrant house-object, owner, guest-list, and mover-
-  monarch mutations plus null/fresh/equal-revision ABA replacement. Direct
-  retained-object setters, replacement/removal/clear observer lifetime, shared
-  multi-table ownership, and frozen guest-map input are covered explicitly.
- Re-entrant reset and delete/GUID-reuse convergence plus activation-lease
-  overwrite prevention after an external body/controller clear.
- Post-ownership position, vector, object-description, Create, identity,
-  body, and controller authority replacement.
- Terminal stale-controller rejection after replacement, reset, and disposal.
- Body/controller epochs advance only on actual ownership changes.
-
-The checkpoint-6 focused publication/collision suite passes 129/129, the
-focused Core shadow transaction suite passes 16/16, and the complete Runtime
-project passes 695/695 under invariant globalization. The Runtime Release build
-passes with zero warnings and zero errors. Broader Core/App/solution and
-connected gates remain for the parent integration checkpoint. Under the
-machine's Swedish current culture, the three previously known formatting
-assertions remain unrelated (`0,5` versus `0.5` and localized sky text), so the
-canonical Runtime gate runs under invariant globalization.
-
-## Next checkpoint
-
-Cut the graphical and no-window local-player hosts over to this Runtime-owned
-activation transaction, then delete their duplicate SetPosition
-activation/publication paths. The cutover must preserve the same exact body,
-controller, shadow payload, deferred-cell lease, collision receipt ordering,
-and graceful teardown proven here; no host may reconstruct or replay the
-canonical transaction.

-# Runtime SetPosition authored mover preparation - 2026-08-01
-
-## Scope
-
-This is placement Slice 4B2 checkpoint 3. It adds the dormant,
-presentation-independent preparation contract used to turn an accepted Runtime
-position into retail's exact `CPhysicsObj::SetPosition` mover input. No App or
-Headless production route consumes the contract yet, so game behavior is
-unchanged and AP-1/AD-1 remain open.
-
-## Retail oracle
-
-The implementation was checked against the named September 2013 client:
-
- `PhysicsDesc::PhysicsDesc` `0x0051D4D0`
- `PhysicsDesc::UnPack` `0x0051DDD0`
- `CPhysicsObj::set_description` `0x00514F40`
- `CPhysicsObj::SetPosition` `0x005160C0`
- `SPHEREPATH::init_sphere` `0x0050C670`
- `CPartArray::GetNumSphere` `0x00518060`
- `CPartArray::GetSphere` `0x00518070`
- `CPartArray::GetStepUpHeight` `0x005180D0`
- `CPartArray::GetStepDownHeight` `0x005180F0`
- `CTransition::init_object` `0x00509E40`
- `OBJECTINFO::init` `0x0050CF30`
-
-SetPosition calls `CTransition::init_object(..., state = 0)` directly. It does
-not use the ordinary-movement `CPhysicsObj::get_object_info` path. Consequently
-the SetPosition state carries the player/PK/PKLite/impenetrable classifications
-(plus acdream's pointer-free entry-restriction carrier), but it does not add
-Contact, OnWalkable, PathClipped, FreeRotate, or EdgeSlide. Ethereal and
-`step_down = !Missile` are separate `OBJECTINFO` fields derived from the current
-physics state.
-
-## Exact preparation contract
-
- Runtime captures the complete accepted server frame under the exact entity,
-  session, position, vector/velocity, wire-state, final-physics-state mutation,
-  object-description, and create-integration authorities. A host cannot
-  substitute a second position.
- Collision-world X/Y uses the target landblock's active live-centered offsets;
-  full cell ID, cell-local XYZ, and the complete quaternion remain unchanged.
- Setup resolution is bound to the canonical Setup DID. A known but unavailable
-  Setup remains retryable. Resolved-absent is valid only when the canonical
-  object has no Setup. An authored empty Setup remains distinct and still
-  contributes its scaled StepUp/StepDown heights.
- The complete ordered Setup sphere list is retained. Core later applies
-  retail's `min(count, 2)` traversal cap. The successfully resolved no-PartArray
-  or zero-sphere arm reaches Core with an empty list, where SetPosition supplies
-  the retail dummy sphere `(0,0,0.1)`, radius `0.1`, scale `1.0`.
- Scale precedence is `PhysicsDesc.Scale ?? EntitySpawn.ObjScale ?? 1.0`.
-  Present zero and finite negative values are preserved. Scale is not consumed
-  by a resolved-absent dummy mover.
- Every authored command is sealed to the exact preparation operation. Manual,
-  stale, replaced, or merely value-equivalent commands cannot bypass the seal.
- A wire-state, final-state mutation (including NoDraw and missile-stop),
-  vector/velocity, description, or create change during a deferred cell wait
-  returns the resident to `AwaitingPreparation`; the stale mover is never
-  replayed when the collision generation wakes.
- Preparation mutates no body, clock, FullCell, spatial/shadow registration,
-  bucket, camera, world entity, or presentation resource.
-
-Legacy direct SetPosition remains a distinct token mode so the dormant slice
-does not change existing call sites or their warmed allocation ceiling. If a
-legacy operation becomes deferred and later needs new authored data, the
-presence of Runtime's preparation authority makes the exact seal mandatory.
-
-## Ownership and validation
-
-`RuntimeSetPositionState` owns one exact-key preparation-authority entry only
-for operations which require authored preparation. The entry dies with the
-operation on replacement, acknowledgement, cancellation, delete, session
-reset, or disposal and participates in terminal convergence accounting.
-
-Preparation-only validation checks the exact cell frame, live-centered world
-position, values consumed by the first two retail spheres, Setup-derived step
-heights, line/scatter inputs, and bounded scatter attempts. The legacy direct
-validator retains its prior behavior, including retail's dummy-sphere and
-first-two-sphere semantics.
-
-## Gates and review
-
- Focused authored-mover plus SetPosition residence tests: 80/80.
- Runtime Release build: zero warnings and zero errors.
- Complete Runtime project under invariant culture: 595/595.
- Complete Release solution with installed DAT/pak fixtures: 10,342 passed /
-  4 intentional skips.
- Retail-conformance review: canonical frame, DID binding, scale/step/sphere
-  behavior, exact SetPosition flags, and deferred wake checked against the
-  named addresses above.
- Architecture/adversarial review: command sealing, legacy promotion,
-  replacement, deferred wake, direct compatibility, allocation, reset, GUID
-  reuse, and ownership convergence checked.
-
-The three ordinary current-culture Runtime failures are pre-existing Swedish-
-locale formatting assumptions (`0,5` versus `0.5` and localized sky text); the
-same complete project passes under invariant culture.
-
-## Next checkpoint
-
-Implement the dormant atomic local-player physics publication transaction:
-prepare a private controller/body/clock without canonical mutation, evaluate
-SetPosition against that candidate, then publish the exact same body relation
-to `RuntimeEntityRecord` and `RuntimeLocalPlayerMovementState` in one callback-
-free Runtime commit. App and Headless production activation remains a later
-checkpoint.

-# C3c production placement cutover — closeout (2026-08-02)
-
-Behavior commit: `529e0e9d` (68 files, +5,979/−833, register rows AD-61 +
-AD-42 refresh in-commit). Plan:
-[`2026-08-02-placement-cutover.md`](../plans/2026-08-02-placement-cutover.md).
-Session evidence trail: the campaign scratchpad's `implementer-progress.md`
-sections `Continuation 1-4`, `C3c-F1`..`C3c-F5`, `C3c-R1` (not committed;
-summarized here).
-
-## What shipped
-
-Both production hosts (graphical + headless) register every initial
-wire Create through the C0-C3b residence/executor/conductor machinery.
-One shared `RuntimeFirstEntryDriveController` pumps the local-player and
-remote conductors from the placement-receipt flow (per-frame graphical,
-per-tick headless). `MaterializeProjection`/`RebucketLiveEntity` are
-presentation-only strictly while the initial-create residence is ACTIVE
-(exact-token check; `ExecutorCompleted` is the presentation-binding
-receipt); post-residence entities take the full legacy path including
-retail's `prepare_to_enter_world` (0x00511FA0) clock rebase.
-`RuntimeLocalPlayerMovementState.Controller`'s setter is sealed; every
-controller mutation flows through the publication lifecycle. Content-less
-headless sessions (validated-legal config) keep the pre-flip direct
-registration until C4/C5 revisit.
-
-## The five fix slices (each connected-gated inside the cutover)
-
- **F1** — live movement-stat + server-physics application moved behind
-  Runtime ownership (`RuntimeMovementStatsApplication`,
-  `ApplyServerPhysicsState`); the post-logout ingest crash on the
-  retired controller is eliminated; `RuntimeMovementSkillProjection`
-  deleted.
- **F2** — the login activation wedge (world never revealed): the
-  collision-admission prefix gate factored out of the seal (reentrant
-  commit could yield terminal `RejectedAuthority`), the rearm's
-  generation identity corrected (parked G vs post-retirement G+1), and
-  `PlayerModeAutoEntry` now requires the Runtime-published controller
-  (`IsPlayerControllerReady` was a constant `true` — one early attempt
-  permanently sealed the reveal).
- **F3** — landblock-prefix `0`-sentinel replaced by explicit absent-id
-  representation; map-corner landblocks (grid row/col 0, e.g.
-  `0x0000FFFF`) are legal through admission, park/rearm/retire,
-  quiescence, and outdoor shadow seeds.
- **F4** — diagnosis only: the nine-stop soak's convergence failure
-  (pendingPublications=1, farBacklog nonzero, landblock/mesh dimensions)
-  is **pre-existing `6b28ff99`** (2026-07-31, "make collision activation
-  starvation-free"): every far publication clones the complete collision
-  world (median ~19.7k leaves / 3.64 ms), so the queue drains ~10
-  landblocks/s and never catches its window. Fix requires an O(changed)
-  clone (structural sharing or per-landblock atomic unit) — a semantics
-  change to that slice's asserted one-leaf-per-step invariant; scheduled
-  as its own slice BEFORE C5 (whose gate matrix includes the soak).
- **F5** — local-player first-entry ground contact: retail seeds contact
-  from the first gravity frame's transition touch (`enter_world`
-  0x00516170 carries no seed; local player and remotes share the
-  mechanism via `HandleCreateObject` 0x00454C80). The shared
-  `SpawnPlacementSettler` (moved App→Core) runs at `FinalizeActivation`
-  exactly once; genuinely airborne spawns stay airborne; the outbound
-  contact bit chain is asserted end-to-end. The legacy path's
-  unconditional `Contact|OnWalkable|Active` force-seed (non-retail, no
-  plane) still runs during candidate preparation and is OVERWRITTEN by
-  the faithful settle (register AD-61). Fixes the user-observed
-  standing-cast "You can't do that while in the air!" rejections.
-
-## Review round R1 (dual Opus: initial FAIL 2+2 MAJOR → delta PASS both)
-
-Retail MAJORs: the login constraint leash (deleted with the legacy
-resolve path; re-armed at the committed placement in
-`FinalizeActivation` — `HandleReceivedPosition` 0x00453FD0 arms on every
-accepted position) and the post-residence rebucket scope (fixed to
-exact-token active-residence). Adversarial MAJORs: content-less headless
-(no drive → legacy registration) and the register rows. Nine minors
-fixed (owner conversion API with active-residence throw, wire-landblock
-guards, drive-pending ledger in `IsConverged`, route attach/detach
-latch, celless conversion for far headless remotes, doc-comment truth,
-per-incarnation cylinder cache, executor-drain drift model documented +
-source-pinned); two tracked (#276, #277 in ISSUES).
-
-## Final gates
-
-Runtime 1,003; App 4,039/3 skips; Headless 79; complete solution
-**10,816 / 0 failed / 4 skips** (Release, `-m:1`). Connected
-lifecycle/reconnect gate **PASS** (`connected-world-gate-20260802-175401`;
-graceful exits, world-visible, zero airborne-rejection strings; run
-`-174811` failed on user-interference fingerprint —
-`activeTeleportCount=1` at the stable checkpoint — and is attributed,
-not counted). The soak stays red for the pre-existing F4 attribution.
-
-## Process lessons (carried to memory)
-
-1. **Report artifacts over marker logs** — three wrong classifications
-   this campaign came from reading route/marker logs instead of
-   `report.json` (the soak "clean route" was Passed=false with 37
-   convergence failures).
-2. **Log lifetime before absence claims** — a 26-second, 67-line log's
-   silence about a defect proves nothing (the 122749 misread inverted a
-   root-cause classification twice).
-3. **User observation is the cheapest gate** — the standing-cast
-   airborne rejections and the black-screen reveal were both
-   user-spotted minutes before harness detection.
-4. **The seal finds the bypasses** — sealing the controller setter
-   surfaced a runtime-mutation bypass (F1) the compile-break audit could
-   not see; expect the same class when sealing any long-lived escape
-   hatch.

-## 1. Every writer of `RuntimeEntityRecord.PhysicsBody`
-
-`PhysicsBody` is `public PhysicsBody? PhysicsBody { get; private set; }`
-(`src/AcDream.Runtime/Entities/RuntimeEntityRecord.cs:72`). The ONLY mutator is
-the internal method `SetPhysicsBody(PhysicsBody? body)`
-(`RuntimeEntityRecord.cs:176-182`):
-```
-internal void SetPhysicsBody(PhysicsBody? body)
-{
-    if (ReferenceEquals(PhysicsBody, body)) return;
-    PhysicsBody = body;
-    PhysicsOwnershipEpoch++;   // <-- the ONLY place PhysicsOwnershipEpoch is bumped
-}
-```
-So every "writer" is a caller of `.SetPhysicsBody(...)` (all 6 call sites, confirmed
-by full-repo grep, zero others):
-
-1. **`RuntimeEntityDirectory.cs:359`** — inside
-   `GetOrCreatePhysicsBody(RuntimeEntityRecord record, Func<incarnation,PhysicsBody> factory)`
-   (need exact surrounding signature — read below). Public/internal API used by
-   the route-1 "SECOND, narrower body-construction duplicate authority" for
-   non-player static-animating physics objects
-   (`DatLiveEntityProjectionMaterializer.cs:1003-1016`, per the route inventory).
-   Guard: only sets if record has no body yet (idempotent-create pattern) — see
-   full read below for exact guard.
-2. **`RuntimeEntityObjectLifetime.cs:766`** — `Entities.SetPhysicsBody(canonical, null)`
-   inside a teardown method (need to confirm exact method — likely delete/retire
-   path, paired with `Entities.SetPhysicsBodyAcquisitionInProgress(canonical, false)`
-   at line 767 in the SAME method). Clears body on deletion/teardown.
-3. **`RuntimeLocalPlayerPhysicsPublicationState.cs:405`** — `candidate.Record.SetPhysicsBody(candidate.Body)`
-   inside `Commit(token, out activationToken)` (lines 373-411). **THIS IS THE
-   DORMANT OPTION-2 MECHANISM** — see section 4 below. Guarded by `IsCurrent(candidate)`
-   (epoch/session/identity/null-state re-check, lines 891-922) immediately before,
-   and by `_physics.SetPosition.PrepareDormantLocalActivationOwnership(...)` called
-   first (line 394) as the "seal the exact SetPosition owner before the
-   irreversible no-fail suffix" step — i.e. this call site DOES chain into
-   PrepareDormantLocalActivationOwnership per task 4's target.
-4. **`RuntimeLocalPlayerPhysicsPublicationState.cs:1025`** — `_entities.SetPhysicsBody(activation.Record, null)`
-   inside `DiscardActivation()` (994-1032), the rollback/teardown path for the
-   SAME dormant mechanism — only fires if `_entities.IsCurrent(activation.Record)`
-   AND `ReferenceEquals(activation.Record.PhysicsBody, activation.Body)` (i.e.
-   never clobbers a body some OTHER newer owner already installed — the exact
-   anti-pattern the rejected prototype failed on).
-5. **`RuntimePhysicsState.cs:1558`** — `Entities.SetPhysicsBody(record, candidateBody)`
-   — need full read; this is inside the remote/projectile body-binding family
-   (see section 3).
-6. **`RuntimePhysicsState.cs:1666`** — `Entities.SetPhysicsBody(record, candidate)`
-   — need full read; this is the OTHER binding site, guarded by
-   `PhysicsBodyAcquisitionInProgress` (set true at :1645, cleared at :1676/1678).
-
-**Writer count: 6 call sites, across 3 files** (`RuntimeEntityDirectory.cs` x1,
-`RuntimeEntityObjectLifetime.cs` x1, `RuntimeLocalPlayerPhysicsPublicationState.cs` x2,
-`RuntimePhysicsState.cs` x2).
-
-## Consumers of `PhysicsOwnershipEpoch`
-
-Only bumped in one place (`RuntimeEntityRecord.SetPhysicsBody`, above). Consumers
-(all in `RuntimeLocalPlayerPhysicsPublicationState.cs`) treat it as a
-compare-and-reject epoch stamped into every token/activation struct:
- `RuntimeLocalPlayerPhysicsPublicationToken.PhysicsOwnershipEpoch` (field, :53)
-  captured at `Prepare` time (:314).
- `RuntimeLocalPlayerPhysicsActivationToken.PhysicsOwnershipEpoch` (:70) captured
-  as `token.PhysicsOwnershipEpoch + 1UL` (:328) — i.e. the activation token
-  encodes "the epoch AFTER my own commit bumps it", so `IsActivationCurrent`
-  (931-962) and `IsActivationOwnershipEnvelopeCurrent` (717-745) comparing
-  `activation.Record.PhysicsOwnershipEpoch == activation.Token.PhysicsOwnershipEpoch`
-  will FAIL (reject) the instant any OTHER writer (remote/projectile bind, GC
-  clear, non-player static body creation via `RuntimeEntityDirectory` — none of
-  which should ever touch a local-player record, but the check is defense-in-depth)
-  touches the same record's PhysicsBody between prepare and commit.
- `IsCurrent(candidate)` (891-922, pre-Commit re-check) also compares
-  `candidate.Record.PhysicsOwnershipEpoch == candidate.Token.PhysicsOwnershipEpoch`
-  (unincremented — i.e. "nobody touched the body between Prepare and Commit").
-
-**This IS the reentrancy defense the rejected prototype lacked** — see section 6.
-
-## 2. The two production local-player controller constructions, end to end
-
-### Graphical: `PlayerModeController.BuildControllerAndCamera`
-`src/AcDream.App/Input/PlayerModeController.cs:244-525`. Constructor list
-(52-74) shows it is injected with `RuntimeLocalPlayerMovementState controllerSlot`
-(the SAME slot type headless writes) — confirms the route-inventory's "open
-question" (2026-08-02-cutover-route-inventory.md:204-207): **App DOES write
-`_controllerSlot.Controller = controller` directly, at line 486.** Not a
-mystery/asymmetry — both hosts write the exact same public setter.
-
-Steps, in order:
-1. `_approachCompletions.BeginControllerLifetime()` (250) — App-only approach
-   lifecycle token.
-2. Capture rollback snapshots: `_camera.CaptureState()` (255),
-   `_shadow.Capture()` (256) — presentation-only.
-3. `new PlayerMovementController(_physics, playerRecord.ObjectClock, PlayerMovementConstructionOptions.From(_skills.Snapshot))`
-   (259-262) — **uses the PUBLIC constructor**, whose default publication
-   lifecycle is `StandalonePublished` (`PlayerMovementController.cs:617-626`),
-   NOT `CandidatePreparing`/`CreatePublicationCandidate`. This is the key
-   divergence from the dormant mechanism (section 4): this controller never
-   enters the `CandidatePreparing -> CandidateSealed -> RuntimeOwnedDormant ->
-   RuntimePublished` lifecycle at all.
-4. Builds `MoveToManager`/`EntityPhysicsHost` closures over captured locals
-   (267-346) — presentation-adjacent glue, host-specific.
-5. `EntityPhysicsHostComposition.SelectStableHostWithoutRebind` (347-350) —
-   canonical-state read (checks `LiveEntityRecord.PhysicsHost`).
-6. `RuntimeMovementSkillProjection.ApplyTo(_skills, controller)` (366-368).
-7. `ApplyStepHeights(controller, playerEntity, playerGuid)` (375) — **reads
-   `DatReaderWriter.DBObjs.Setup` directly** (per headless's own comment
-   contrasting itself, `HeadlessSessionWorldProjection.cs:685-689`) — NOT
-   through the prepared-collision/`IPreparedCollisionSource` seam headless
-   uses. Divergence #1.
-8. `_controllerSlot.BeginMotionPreparation(controller, drainPriorAnimationQueue)`
-   (404-407) — the ONE existing narrow "preparation lease" concept already in
-   `RuntimeLocalPlayerMovementState` (separate from the dormant physics
-   publication state) that lets a synchronous PartArray/type-5 completion
-   reach the candidate `MotionInterpreter` before publish.
-9. **Duplicate authority** — `_physics.Resolve(...)` (409-413) then
-   `_physics.ResolvePlacement(...)` (422-430) — direct canonical-state-free
-   collision resolve, entirely outside `RuntimeSetPositionState`.
-10. `controller.PreparePositionForCommit(...)` (434-437),
-    `controller.SetBodyOrientation(...)` (438).
-11. Camera construction + `_camera.EnterChaseMode(...)` (440-447) —
-    presentation-only, but happens BEFORE the final canonical commit (445-447
-    precede line 482-484) — i.e. camera activation today is NOT gated on a
-    Runtime placement acknowledgement.
-12. Re-check host stability (449-458) — throws if the host changed during
-    camera activation (defensive, but ad hoc — not an epoch/token check, a
-    bespoke `ReferenceEquals` re-read).
-13. Shadow sync (`_shadow.SyncPose(...)`, 460-466).
-14. `EntityPhysicsHostComposition.InstallOrRebind(...)` (472-475) + another
-    `ReferenceEquals` stability re-check (476-480).
-15. **Duplicate authority — final commit** (482-484):
-    `playerEntity.SetPosition(initial.Position); playerEntity.ParentCellId =
-    initial.CellId; controller.CommitPreparedPosition();` — direct writes to
-    the App-side `WorldEntity`/render sidecar AND `controller`'s own internal
-    frame, bypassing any Runtime `Place` receipt or `RuntimeEntityRecord`
-    write. **`RuntimeEntityRecord.PhysicsBody`/`PhysicsOwnershipEpoch` are
-    NEVER touched anywhere in this method** — `controller.PhysicsBody` (the
-    `_body` field created in step 3) stays a private field of the
-    `StandalonePublished` controller; nothing calls
-    `Entities.SetPhysicsBody(playerRecord, controller.PhysicsBody)`. This
-    means TODAY the canonical `RuntimeEntityRecord.PhysicsBody` slot for the
-    graphical local player is **never populated at all** by this path — a
-    previously-unstated confirmation that `SubmitPreparedPlacement`'s
-    `operation.Record.PhysicsBody is not { } body` requirement (section 3)
-    would REJECT any ordinary (non-initial) SetPosition submitted for the
-    graphical local player today, because no writer ever puts a body on that
-    record. (Route 2's "ForcePosition" duplicate authority,
-    `LocalForcePositionTransaction`, works around this by mutating
-    `PlayerMovementController`'s own body directly via `BlipPosition`, never
-    touching `RuntimeEntityRecord.PhysicsBody` either — internally consistent
-    with each other, both equally disconnected from the canonical record.)
-16. Slot commits (485-492): `_hostSlot.Host`, `_controllerSlot.Controller =
-    controller` (the public, unguarded setter — bumps `ControllerOwnershipEpoch`
-    unconditionally, see section 4), `_chase.Legacy/Retail`, `_mode.IsPlayerMode
-    = true`.
-17. `catch`: rolls back camera + shadow only (494-518); does NOT roll back
-    steps 15-16 because those are the LAST lines before `lifetimeCommitted =
-    true` — structurally "hope nothing after this throws" rather than an
-    explicit no-fail invariant.
-
-**Canonical-state mutations in this method: NONE on `RuntimeEntityRecord`**
-(no `SetPhysicsBody`, no `SetFullCell`, no object-clock call) — everything
-mutated is App-local (`WorldEntity`, `PlayerMovementController`'s private
-body, `RuntimeLocalPlayerMovementState.Controller`,
-`LocalPlayerPhysicsHostSlot`, camera, shadow). The ONLY canonical-record
-writes for the local player's initial placement happen earlier in the
-hydration pipeline (`LiveEntityRuntime.MaterializeLiveEntity`/
-`RebucketLiveEntity`, route 1 hops 9-11) — entirely disjoint from this method.
-
-### Headless: `HeadlessSessionWorldProjection.CreateController` + `SynchronizeLocalPlayer`
-`src/AcDream.Headless/Hosting/HeadlessSessionWorldProjection.cs:566-655`
-(read in full).
-
-`SynchronizeLocalPlayer` (566-615):
-1. Guards on `record.ServerGuid == _runtime.PlayerIdentity.ServerGuid` and a
-   present `Snapshot.Position` (568-573).
-2. `_collision.CenterOn(position.LandblockId)` (575) — headless collision-
-   neighborhood readiness, no graphical analog.
-3. `_runtime.MovementOwner.Controller ?? CreateController(record)` (576-578)
-   — lazy-construct-once via the SAME public `Controller` getter/setter
-   `RuntimeLocalPlayerMovementState` exposes; no reentrancy guard against two
-   concurrent calls both observing `null` (single-threaded host loop makes
-   this safe in practice today, not structurally).
-4. `_runtime.EntityObjects.Physics.Engine.Resolve(...)` (589-594) then
-   `.ResolvePlacement(...)` (595-605) — **the exact same duplicate-authority
-   shape as graphical step 9**, hardcoded `DefaultRadius`/`DefaultHeight`
-   constants (visible in the call, actual values not read here) instead of
-   `_motionBindings.GetSetupCylinder`.
-5. `controller.SetPosition(...)` + `controller.SetBodyOrientation(...)`
-   (610-614) — **duplicate final commit**, headless's version of graphical
-   step 15. Also never touches `RuntimeEntityRecord.PhysicsBody`.
-
-`CreateController` (639-655):
-1. `new PlayerMovementController(_runtime.EntityObjects.Physics.Engine, record.ObjectClock, PlayerMovementConstructionOptions.From(_runtime.CharacterOwner.MovementSkills.Snapshot))`
-   (642-646) — **same PUBLIC constructor / `StandalonePublished` lifecycle**
-   as graphical step 3.
-2. `ApplySetupStepHeights(record, controller)` (649, body at 657-691) —
-   **reads via `_preparedCollision.ReadSetupCollision(setupId)`** (668-679),
-   the prepared-asset seam, NOT raw DAT — divergence #1 mirrored (headless
-   uses the "correct"/prerequisite-B-aligned source; graphical does not).
-   **Throws `InvalidDataException`** if the read status isn't `Loaded`
-   (672-675) — propagates uncaught up through `SynchronizeLocalPlayer` ->
-   `ProjectSpawn`/`ProjectPosition` -> the wire-dispatch call chain. This IS
-   gate 10 (late headless prepared-collision failure) manifesting today as an
-   unhandled exception, not a retry.
-3. `RuntimeMovementSkillProjection.ApplyTo(_runtime.CharacterOwner.MovementSkills, controller)`
-   (650-652).
-4. `_runtime.MovementOwner.Controller = controller;` (653) — **the exact
-   same public setter graphical step 16 uses.**
-
-**No headless equivalent of graphical steps 1 (approach lifetime), 8 (motion
-preparation lease), 11-14 (camera + host-stability re-checks), 17 (camera/
-shadow rollback)** — headless has no camera/shadow/approach concept at all
-(confirmed, matches the route inventory's "No headless equivalent of
-graphical hops 12-14/19").
-
-### Top divergences between the two hosts (summary)
-1. **Setup/collision data source**: App reads raw DAT (`ApplyStepHeights` via
-   `_dats`/`_datLock`); headless reads the prepared/baked asset
-   (`ApplySetupStepHeights` via `IPreparedCollisionSource`). Same target
-   values, different pipeline — a real fidelity risk if the two ever diverge
-   (baking staleness).
-2. **Default cylinder fallback**: App falls back to `0.48f`/`1.835f` inline
-   (`PlayerModeController.cs:416-420`) when `GetSetupCylinder` returns
-   `< 0.05f` radius; headless uses named `DefaultRadius`/`DefaultHeight`
-   constants at the `ResolvePlacement` call site (:599-600) — same intended
-   values, defined in two places.
-3. **Failure handling**: App's `BuildControllerAndCamera` has an explicit
-   try/catch/rollback for camera+shadow; headless's `CreateController`/
-   `ApplySetupStepHeights` has NO surrounding try/catch — a prepared-collision
-   read failure is a raw unhandled exception today.
-4. **Presentation surface**: App additionally owns approach-completion
-   lifetime, motion-preparation lease, chase camera, shadow sync — none of
-   which headless has or needs.
-5. **Neither host touches `RuntimeEntityRecord.PhysicsBody`, `PhysicsOwnershipEpoch`,
-   or any `RuntimeSetPositionState` API** — both are 100% off to the side of
-   the canonical record, confirmed by exhaustive grep (section 1's 6 writer
-   call sites do not include either `PlayerModeController.cs` or
-   `HeadlessSessionWorldProjection.cs`).
-
---
-
-## 3. Every other body binding/consumer
-
- **Remote dead-reckoning** (`RuntimeRemotePhysicsUpdater.cs` — flagged
-  protected/dirty, read-only, NOT modified): grep confirms it only READS
-  `record.PhysicsBody` via `ReferenceEquals(record.PhysicsBody, remote.Body)`
-  currency checks (line 817) — it does not call `SetPhysicsBody`. The actual
-  writer for remote motion is `RuntimePhysicsState.SetRemoteMotion`
-  (`RuntimePhysicsState.cs:1446-1570`, full read) — throws
-  `InvalidOperationException` on: binding-already-in-progress (1460-1464),
-  body-would-be-replaced when a body already exists and doesn't match
-  (1487-1492), losing an existing remote-placement contract (1493-1498), or
-  post-callback ownership drift detected via a captured
-  `sessionVersion`/`expectedBody`/`expectedRuntime` triple re-checked after
-  the bind callback (1539-1549, "changed ownership during remote-motion
-  binding"). Calls `Entities.SetPhysicsBody(record, candidateBody)` (:1558)
-  ONLY when `expectedBody is null` (first bind) via `InitializeNewPhysicsBody`
-  (:1556) — i.e. this is throw-on-conflict exclusivity (Option-1 flavor), not
-  epoch/token gating. For a LOCAL PLAYER record this path should never fire
-  (remote motion is for non-local entities) but the guard is defense-in-depth
-  and IS one of the explicit gate checks
-  (`!activation.Record.RemoteMotionBindingInProgress`/`RemoteMotion is null`)
-  the dormant local-publication mechanism re-validates at every stage
-  (section 4).
- **Projectile binding**: `RuntimeProjectilePhysicsUpdater.cs` similarly only
-  READS `record.PhysicsBody` (lines 447, 459, `ReferenceEquals` currency
-  checks). The writer is `RuntimePhysicsState.BindProjectile`
-  (`RuntimePhysicsState.cs:1309-1382`, full read) — same throw-on-conflict
-  shape: binding-in-progress (1343-1347), body-mismatch on rebind
-  (1330-1337), must-already-own-canonical-body-before-binding
-  (1348-1352, "projectile must borrow its canonical physics body" — i.e.
-  UNLIKE remote motion, `BindProjectile` requires `record.PhysicsBody` to
-  ALREADY be non-null and matching BEFORE it will bind — it never calls
-  `InitializeNewPhysicsBody`/`SetPhysicsBody` itself for a first-time body;
-  something else (route 5's `ProjectileController.TryBind`,
-  `ProjectileController.cs:176-265` per the route inventory) must construct
-  the body ad hoc first via a DIFFERENT path than `GetOrCreatePhysicsBody`
-  — worth flagging: **this is a 7th, App-side, ad hoc body-construction site
-  not funneled through any of the 6 canonical writer methods** — App's
-  `ProjectileController.TryBind` constructs a body and must be setting it onto
-  the record through some other route (not confirmed by this pass; App-side
-  `ProjectileController.cs` was not read in full — flag as open item, but it
-  is explicitly OUT of C1's local-player scope per the campaign handoff's
-  gate list item "remote and projectile binding/update" being about
-  *interaction with* the local-player transaction, not projectile's own
-  authority).
- **`RuntimeSetPositionState.SubmitPreparedPlacement`** (`RuntimeSetPositionState.cs:2224-2274`,
-  full read): requires `operation.Record.PhysicsBody is not { } body` to
-  already be true (line 2254) — i.e. EVERY non-initial-construction
-  SetPosition submission (ForcePosition, portal, remote Position, projectile
-  correction) requires a body to already exist on the record, confirming the
-  6 writer sites in section 1 are the exhaustive set of "who can put the
-  FIRST body on a record." For the local player specifically, only
-  `RuntimeLocalPlayerPhysicsPublicationState.Commit` (section 4) does this
-  today (dormant, unwired); in PRODUCTION, no writer ever populates
-  `RuntimeEntityRecord.PhysicsBody` for either host's local player (section
-  2 finding) — meaning `SubmitPreparedPlacement` would reject a local-player
-  submission in production today, which is consistent with the route
-  inventory's finding that Route 2 (ForcePosition) and Route 3 (portal) both
-  bypass `RuntimeSetPositionState` entirely via their own duplicate
-  authorities instead.
- **`RuntimeSetPositionState.PrepareDormantLocalActivationOwnership`**: see
-  section 4 — the ONE place the local-player-specific dormant body attach
-  happens; requires a pre-opened `Operation` in stage `AwaitingPreparation`
-  from `TryBeginExclusiveAuthoredPlacement`.
- **Object-clock epoch transitions**
-  (`RuntimeEntityRecord.SuspendObjectClock`/`ResetObjectClockForEnterWorld`,
-  both `internal`, bump `ObjectClockEpoch`): full call-site grep found BOTH
-  the expected `RuntimeEntityDirectory` wrapper call sites (which run
-  `EnsureKnown(record)` first, `RuntimeEntityDirectory.cs:311-321`) AND
-  **direct unwrapped calls from `src/AcDream.App/World/LiveEntityRuntime.cs`
-  at lines 879, 891, 897, 1258, 3030, 3033** — App calls
-  `record.SuspendObjectClock()`/`record.ResetObjectClockForEnterWorld(...)`
-  straight on the `RuntimeEntityRecord` (accessible because these are
-  `internal` and `AcDream.App` has `InternalsVisibleTo`), bypassing the
-  `RuntimeEntityDirectory` facade's `EnsureKnown` check entirely. This is
-  inside `LiveEntityRuntime`'s `RebucketLiveEntity`-family code (comment
-  references `prepare_to_enter_world`/retail `update_object`'s parent
-  early-out — matches the already-known route-1/prerequisite-D
-  `RebucketLiveEntity` duplicate authority). **Previously-unstated
-  implication for C1**: the SAME record whose `ObjectClockEpoch` the dormant
-  publication mechanism gates on can have its epoch bumped by this
-  direct-call path DURING the window between
-  `RuntimeLocalPlayerPhysicsPublicationState.Prepare` and `.Commit()`/
-  `.CommitActivation()` if `RebucketLiveEntity` runs concurrently for the
-  SAME entity (e.g. a second CreateObject/Position causing a re-rebucket
-  mid-construction) — the epoch check (`IsCurrent`/`IsActivationOwnershipEnvelopeCurrent`
-  comparing `record.ObjectClockEpoch == token.ObjectClockEpoch`) WOULD catch
-  and reject this correctly (fail-safe), but it confirms the gate is load-
-  bearing against a REAL, already-existing production writer, not a
-  hypothetical.
- **Deletion/teardown**: `RuntimeEntityObjectLifetime.TryAcceptDelete`
-  (`RuntimeEntityObjectLifetime.cs:1555+`) calls `Entities.TryDelete` then
-  `Entities.RemoveActive(active)` (1587) — this IMMEDIATELY flips
-  `Entities.IsCurrent(record)` to `false` for that record (removes it from
-  the active-by-guid table), which is the single check
-  `CanPrepare`/`IsCurrent`/`IsActivationCurrent`/every gate in section 4
-  depends on — so a delete landing at any point rejects the in-flight
-  publication transaction on its NEXT check. Full body clear happens later
-  in `RuntimeEntityObjectLifetime.CompleteProjectionRetirement`
-  (:745-771, called from `RetireCanonicalOnly`/the graphical teardown-ack
-  path): `Entities.SetPhysicsBody(canonical, null)` (:766) after
-  `Physics.SetPosition.Forget(canonical, releasePreparedMover: true)` (:753,
-  cancels any in-flight ordinary placement) and
-  `ForgetInitialCreateResidence(canonical)` (:751, cancels any in-flight
-  residence lease) — i.e. deletion cancels BOTH placement-lease families
-  before clearing the body, consistent with prerequisite E's "quiesce before
-  demote" discipline (though for landblock collision, not entity teardown —
-  the pattern rhymes).
- **`RuntimePhysicsState` per-frame body access**: `RuntimeOrdinaryPhysicsUpdater.cs`,
-  `RuntimeRemotePhysicsUpdater.cs`, `RuntimeProjectilePhysicsUpdater.cs` each
-  gate their per-tick work on `record.PhysicsBody is not { } body` /
-  `ReferenceEquals(record.PhysicsBody, body)` currency checks (grep-confirmed,
-  e.g. `RuntimeOrdinaryPhysicsUpdater.cs:68,284`) — read-only w.r.t. the
-  `PhysicsBody` reference itself (they mutate the BODY's internal fields
-  every tick, which is expected/normal simulation, not an ownership-slot
-  write). No workset iterates and calls `SetPhysicsBody`. `RuntimePhysicsState.cs`
-  itself has only two visible "workset" mentions (`ClearSpatialWorksets` at
-  :1951, a doc-comment at :1307) — the ordinary/remote/projectile worksets
-  live in their respective `RuntimeXPhysicsUpdater` files, out of this pass's
-  read budget beyond the grep-confirmed read-only currency pattern above.

-## 4. `RuntimeSetPositionState.PrepareDormantLocalActivationOwnership` — nucleus or dead end?
-
-**Definition** (`RuntimeSetPositionState.cs:1026-1052`, full read):
-```csharp
-internal void PrepareDormantLocalActivationOwnership(
-    RuntimeEntityRecord record, PhysicsBody body,
-    in RuntimeEntityPlacementToken token)
-{
-    ...
-    if (!token.IsValid
-        || record.Key != token.Entity
-        || !_operations.TryGetValue(token.Entity, out Operation? operation)
-        || operation.Token != token
-        || operation.Stage is not RuntimeEntityPlacementStage.AwaitingPreparation
-        || !ReferenceEquals(operation.Record, record)
-        || record.PhysicsBody is not null       // <- record must have NO body yet
-        || !IsCurrent(operation)
-        || body.InWorld
-        || (body.TransientState & TransientStateFlags.Active) != 0)
-    {
-        throw new InvalidOperationException(
-            "Dormant local activation must bind to the exact current placement owner.");
-    }
-    operation.Body = body;
-    operation.DormantLocalActivation = true;
-}
-```
-It THROWS (does not return a status) on any invariant violation — by design a
-"this should be structurally impossible if the caller validated first"
-assertion, not a retryable rejection. It requires a PRE-EXISTING placement
-`Operation` already opened via `TryBeginExclusiveAuthoredPlacement`
-(`RuntimeSetPositionState.cs:1004-1024`) in stage `AwaitingPreparation` — i.e.
-it is NOT a standalone entry point; it is ONE STEP inside a larger chain that
-also needs prerequisite B's mover-preparation authority
-(`IsExactPreparedPlacementCurrent`, `RuntimeSetPositionState.cs:1318-1340`)
-satisfied for the SAME token/command before
-`RuntimeLocalPlayerPhysicsPublicationState.CanPrepare` will even call it.
-
-**What it was built for**: it is called from exactly ONE place in the whole
-repo — `RuntimeLocalPlayerPhysicsPublicationState.Commit`
-(`RuntimeLocalPlayerPhysicsPublicationState.cs:394-397`), as the "seal the
-exact SetPosition owner before the irreversible no-fail suffix" step,
-immediately before `candidate.Controller.CommitRuntimeOwnership(...)` and
-`candidate.Record.SetPhysicsBody(candidate.Body)`. It exists purely to make
-the PLACEMENT OPERATION (owned by `RuntimeSetPositionState`) and the BODY
-(owned by `RuntimeEntityRecord`) become mutually aware atomically, so that
-the SAME operation can later be walked through the full retail SetPosition
-staged commit (ground phase -> collision dispatch -> response -> final
-commit) via `TryEvaluateDormantLocalActivation` ->
-`TryPrepareDormantLocalActivationCommit` ->
-`TryApplyDormantLocalActivationCommit` ->
-`TryPrepareDormantLocalActivationFinalCommit` ->
-`TryApplyDormantLocalActivationFinalCommit`
-(`RuntimeSetPositionState.cs:2025-2077`, full read of the final-commit
-method) — the LAST of which is where `_entities.SetFullCell`,
-`_entities.AdvancePlacementCommit`, `body.InWorld = true`,
-`_entities.SetPhysicsHost`, `controller.CommitRuntimeActivationFrame()`,
-`_physics.Engine.UpdatePlayerCurrCell`, `_physics.AcknowledgeSpatialProjection`,
-`_entities.ResetObjectClockForEnterWorld` (object-clock epoch bump, task 3),
-and `controller.ActivateRuntimePublication()` (controller goes LIVE) ALL
-happen in one synchronous, no-branch-for-failure block (:2025-2077), gated
-immediately before by `IsDormantLocalActivationPrephaseCurrent`/re-validated
-epoch checks. **This is genuinely the full retail SetPosition commit,
-already ported, already wired to the same body/controller the dormant
-publication candidate built.**
-
-**Verdict: NUCLEUS, not a dead end** — but it is only ONE LOAD-BEARING STEP
-inside a much larger, ALREADY-COMPLETE mechanism:
-`RuntimeLocalPlayerPhysicsPublicationState` (1033 lines,
-`src/AcDream.Runtime/Gameplay/RuntimeLocalPlayerPhysicsPublicationState.cs`)
-+ its ~15 `RuntimeSetPositionState` dormant-activation methods. Constructed
-once at `GameRuntime.cs:261` and exposed via
-`RuntimeLocalPlayerMovementState.PhysicsPublication` (:59-61, itself
-`internal`, throws if unbound). **Confirmed by exhaustive grep: ZERO
-production callers in `src/AcDream.App/` or `src/AcDream.Headless/`** — the
-only callers anywhere are `tests/AcDream.Runtime.Tests/Gameplay/RuntimeLocalPlayerPhysicsPublicationStateTests.cs`.
-This is, functionally, **Option 2 from the rejected-prototype note ("Off-
-canonical preparation followed by one validated atomic Runtime commit that
-publishes the prepared controller/body relationship without copying stale
-state over newer authority") already built end to end** — complete with:
- a `Prepare`/`Commit`/`Discard` triad for the BODY/CONTROLLER pair
-  (analogous to, and reusing, the SAME token-epoch pattern as
-  `RuntimeSetPositionState`'s ordinary placement operations);
- a SEPARATE `EvaluateActivation`/`CommitActivation`/`DiscardActivation` triad
-  for actually driving the body through retail SetPosition's staged commit
-  once the body/controller pair is sealed;
- re-validation of `PhysicsOwnershipEpoch`, `ObjectClockEpoch`,
-  `ControllerOwnershipEpoch`, `SessionLifetimeVersion`, identity
-  `ServerGuid`+`Revision`, and null/in-progress state for RemoteMotion/
-  Projectile/PhysicsHost/DeleteAcceptedForTeardown at EVERY external entry
-  point (`CanPrepare`, `IsCurrent`, `IsActivationCurrent`,
-  `IsActivationOwnershipEnvelopeCurrent`,
-  `IsCommittedActivationSuffixCurrent`) — this IS the reentrancy defense the
-  rejected snapshot-lease prototype explicitly lacked (see section 6).
-
-**What is genuinely missing (the real C1 work), given this mechanism already
-exists:**
-1. Nobody calls `TryBeginExclusiveAuthoredPlacement` + prerequisite B's
-   `PrepareMover`/`ReadSetupCollision` chain + `PhysicsPublication.Prepare`/
-   `Commit`/`EvaluateActivation`/`CommitActivation` from either host — this IS
-   the wiring gap, exactly like every other route in the cutover.
-2. **The public `RuntimeLocalPlayerMovementState.Controller` setter
-   (`RuntimeLocalPlayerMovementState.cs:37-50`) remains a live, unguarded
-   escape hatch** — both `PlayerModeController.BuildControllerAndCamera:486`
-   and `HeadlessSessionWorldProjection.CreateController:653` write it
-   directly today, and NOTHING stops either host from continuing to do so
-   even after C1 wires the dormant mechanism, unless that direct-write path
-   is deleted/sealed off (e.g. made `internal` to only
-   `RuntimeLocalPlayerPhysicsPublicationState`/`CommitRuntimeOwnedController`).
-   The setter has NO epoch/token check on write (`CanCommitRuntimeOwnedController`
-   is a SEPARATE, unused-by-the-setter validation method) — it will happily
-   accept a second unguarded assignment even while a dormant activation is
-   in flight, silently retiring whatever the dormant mechanism just
-   published (`_controller?.RetireRuntimePublication()` at :45, which is a
-   real no-op for anything not currently `RuntimeOwnedDormant`/
-   `RuntimePublished` — see section 6 gate 7). **This is the single most
-   important pre-existing defect C1 must close: the "exclusive" adjective in
-   prerequisite C's "one Runtime-owned exclusive/versioned...transaction"
-   is not yet true while this direct setter remains reachable from hosts.**
-3. Neither `new PlayerMovementController(physics, objectClock, options)`
-   (public ctor, `StandalonePublished`) call site in the two hosts has been
-   swapped for `PlayerMovementController.CreatePublicationCandidate` — until
-   that swap happens, controllers built by either host never enter the
-   `CandidatePreparing/CandidateSealed/RuntimeOwnedDormant/RuntimePublished`
-   lifecycle the dormant mechanism's gates all key off of.
-
---
-
-## 5. `PlayerMovementController` construction requirements
-
-Constructor needs (from both direct-ctor call sites AND
-`CreatePublicationCandidate`, `PlayerMovementController.cs:617-690`):
- `PhysicsEngine physics` (shared engine reference, both hosts pass their own
-  `RuntimePhysicsState`/`_runtime.EntityObjects.Physics.Engine`).
- `RetailObjectQuantumClock? objectClock` — App passes `playerRecord.ObjectClock`
-  (the CANONICAL record's clock, `RuntimeEntityRecord.ObjectClock` at
-  `RuntimeEntityRecord.cs:62`, always non-null per its field initializer);
-  headless passes `record.ObjectClock` identically. The dormant mechanism's
-  `CreatePublicationCandidate` instead passes a THROWAWAY
-  `new RetailObjectQuantumClock()` (`PlayerMovementController.cs:687-688`) at
-  construction time and only swaps in the REAL
-  `candidate.Record.ObjectClock` later, inside `Commit`, via
-  `controller.CommitRuntimeOwnership(candidate.Record.ObjectClock)`
-  (`RuntimeLocalPlayerPhysicsPublicationState.cs:403-404` ->
-  `PlayerMovementController.cs:774-786`) — i.e. the dormant candidate is
-  built against a SCRATCH clock so construction can never observe or mutate
-  the canonical record's real clock before the atomic commit swaps it in.
-  This is exactly the "off-canonical preparation" half of Option 2.
- `PlayerMovementConstructionOptions` (RunSkill/JumpSkill) — both hosts build
-  via `PlayerMovementConstructionOptions.From(<a RuntimeMovementSkillState
-  snapshot>)`; the dormant mechanism's `Prepare` also takes this as a caller-
-  supplied parameter (`Prepare(..., PlayerMovementConstructionOptions
-  options, ...)`, :191) — no divergence in shape, only in WHERE the skill
-  snapshot is read from (App's local `_skills` field vs. headless's
-  `_runtime.CharacterOwner.MovementSkills` vs. the dormant mechanism taking
-  it as a caller parameter either way).
-
-What construction MUTATES (beyond the private `_body`): `LocalEntityId`,
-`StepUpHeight`/`StepDownHeight` (Setup-derived), `SphereList` (Setup-derived,
-prerequisite B territory), `ObjectScale`, initial position/orientation via
-`PreparePositionForCommit`/`SetBodyOrientation`, physics state via
-`ApplyPhysicsState`, `MoveToFactory`/`PositionManager`
-(`MovementManager`/`MotionInterpreter` wiring). ALL of this is exactly what
-`RuntimeLocalPlayerPhysicsPublicationState.Prepare`
-(`RuntimeLocalPlayerPhysicsPublicationState.cs:187-355`) already does against
-its private `CreatePublicationCandidate`-built controller, reading
-`command.Physics.StepUpHeight/StepDownHeight/Spheres/Scale/Position/CellId/
-CellLocalPosition/Orientation` from the CALLER-SUPPLIED
-`RuntimeSetPositionCommand` (i.e. the command already carries everything
-prerequisite B's mover-preparation chain produces) rather than reaching into
-DAT/prepared-collision itself.
-
-**What an "off-canonical preparation followed by one validated atomic commit"
-must DEFER** (confirmed by the dormant mechanism's own design, section 4):
- The record's REAL `ObjectClock` (use a scratch clock during prep).
- `RuntimeEntityRecord.PhysicsBody`/`PhysicsOwnershipEpoch` (never touch the
-  canonical record during prep; only `SetPhysicsBody` inside `Commit`, and
-  only after `PrepareDormantLocalActivationOwnership` succeeds).
- `RuntimeLocalPlayerMovementState.Controller`/`ControllerOwnershipEpoch`
-  (only via `CommitRuntimeOwnedController`, never the public setter, during
-  prep).
- `body.InWorld`/`TransientState.Active` (explicitly forced false during prep,
-  `Prepare`, :292-293) — the body must not be simulatable until the LATER
-  activation commit flips it (`TryApplyDormantLocalActivationFinalCommit`,
-  `body.InWorld = true` at :2056).
- World-residence/host/shadow/camera publication (all deferred to the
-  activation phase / presentation-observer layer, never inside `Prepare`).

-## 6. Adversarial gate list — exact code paths that would race TODAY
-
-(Campaign handoff's list, `docs/research/2026-07-31-remaining-physics-campaign-handoff.md:210-221`.)
-For each: what the ALREADY-BUILT dormant mechanism does (if wired) vs. what
-the CURRENT production direct-construction paths do (today, unwired).
-
-1. **Nested construction** — Dormant: `CanPrepare` requires `_activation is
-   null` AND `record.PhysicsBody is null` AND `_movement.Controller is null`
-   (`RuntimeLocalPlayerPhysicsPublicationState.cs:862-889`) — a second
-   `Prepare` while one is in flight is REJECTED structurally. Today: NEITHER
-   `BuildControllerAndCamera` NOR `CreateController` has any such guard —
-   `CreateController`'s `_runtime.MovementOwner.Controller ?? CreateController(record)`
-   (`HeadlessSessionWorldProjection.cs:576-578`) is a bare null-coalesce, not
-   an atomic test-and-set; only single-threaded host-loop scheduling
-   prevents an actual race today.
-2. **Reentrant SetPosition** — Dormant: every gate re-checks
-   `PhysicsOwnershipEpoch`/`record.PositionAuthorityVersion` currency.
-   Today: `BuildControllerAndCamera`'s final mutation
-   (`playerEntity.SetPosition`/`ParentCellId`/`CommitPreparedPosition`,
-   PlayerModeController.cs:482-484) has zero epoch check — a same-thread
-   reentrant call (e.g. from a nested wire dispatch) would silently
-   clobber with no detection.
-3. **Remote and projectile binding/update** — Dormant: `CanPrepare`/
-   `IsCurrent`/`IsActivationCurrent` all check `record.RemoteMotion is null`,
-   `record.Projectile is null`, `!RemoteMotionBindingInProgress`,
-   `!ProjectileBindingInProgress` (defense-in-depth; should never legitimately
-   fire for a local-player record). Today: no such check exists in either
-   host's direct construction path.
-4. **Deletion and same-GUID new incarnation** — Dormant: `_entities.IsCurrent(record)`
-   checked at every gate; `TryAcceptDelete` -> `RemoveActive` flips this
-   immediately (section 3). Today: `BuildControllerAndCamera`/`CreateController`
-   take a fixed `RuntimeEntityRecord`/`WorldEntity` parameter with NO
-   re-validation against current canonical identity at the final commit.
-5. **Projection-owner replacement** — Dormant: `_entities.SessionLifetimeVersion
-   == token.SessionGenerationAuthority` checked throughout. Today: no
-   generation check in either direct path.
-6. **Object-clock epoch change** — Dormant: `ObjectClockEpoch` compared at
-   every gate (section 3/4). Today: no check; AND there is a REAL, live
-   concurrent writer already in production —
-   `LiveEntityRuntime.cs:879/891/897/1258/3030/3033`'s direct
-   `record.SuspendObjectClock()`/`ResetObjectClockForEnterWorld(...)` calls
-   inside the `RebucketLiveEntity` family (section 3) — this is not a
-   hypothetical gate, it is a currently-active call path on the SAME record
-   type.
-7. **Reset and disposal** — Dormant: `ResetSession()`/`Dispose()` on
-   `RuntimeLocalPlayerMovementState` explicitly cascade into
-   `_physicsPublication?.ResetSession()`/`Dispose()`
-   (`RuntimeLocalPlayerMovementState.cs:244-295`), which tear down
-   candidate/activation state via `ReferenceEquals`-gated clears (never
-   clobbering a newer owner, `DiscardActivation`,
-   `RuntimeLocalPlayerPhysicsPublicationState.cs:1002-1032`). Today's direct-
-   construction controllers are built via the PUBLIC constructor
-   (`StandalonePublished` lifecycle) — **`RetireRuntimePublication()`
-   (`PlayerMovementController.cs:837-846`) only transitions
-   `RuntimeOwnedDormant`/`RuntimePublished` state; it is a NO-OP for
-   `StandalonePublished` controllers** — a previously-unstated finding: TODAY,
-   `ResetSession()`/`Dispose()`/replacing `.Controller` on either host's
-   directly-built controller produces NO explicit lifecycle transition at
-   all; the controller is simply dropped/GC'd. Not a visible bug today
-   (nothing reads `IsRuntimePublished` for these), but it means today's
-   controllers are invisible to the exact teardown bookkeeping C1's target
-   mechanism relies on.
-8. **Commit and rollback after replacement** — Dormant: ALL validation
-   happens before the single canonical mutation
-   (`PrepareDormantLocalActivationOwnership`, which itself throws leaving
-   state untouched on failure); everything after is documented as
-   "callback-free, non-allocating, and cannot fail"
-   (`RuntimeLocalPlayerPhysicsPublicationState.cs:391-393`) — no rollback-
-   after-newer-authority path exists BECAUSE nothing after that point can
-   fail by construction. Today: `BuildControllerAndCamera`'s try/catch rolls
-   back camera+shadow only; the final `playerEntity.SetPosition`/
-   `ParentCellId`/`CommitPreparedPosition` triad (482-484) has nothing after
-   it that can throw, so it's accidentally safe today, not structurally
-   guaranteed.
-9. **Late graphical camera/shadow/host failure** — Today: `BuildControllerAndCamera`
-   DOES handle this (explicit `_camera.RestoreState`/`_shadow.Restore` in the
-   catch block, 494-518) — this is the ONE gate the CURRENT graphical path
-   already handles reasonably. The dormant Runtime-side mechanism has NO
-   camera/shadow concept (presentation-independent by design) — C1 must
-   layer this handling in the PRESENTATION/observer phase (post-Runtime-
-   commit), matching prerequisite D's rule that a host exception must not
-   roll Runtime back, only retry the FIFO head.
-10. **Late headless prepared-collision failure** — Today:
-    `ApplySetupStepHeights` (`HeadlessSessionWorldProjection.cs:657-691`)
-    throws a raw, uncaught `InvalidDataException` (672-675) if the prepared
-    Setup collision isn't `Loaded` — this propagates up through
-    `CreateController` -> `SynchronizeLocalPlayer` -> `ProjectSpawn`/
-    `ProjectPosition` with NO try/catch anywhere in between (grep-confirmed
-    no surrounding try/catch in `HeadlessSessionWorldProjection.cs`'s these
-    methods) — a genuinely unhandled-exception risk in production headless
-    TODAY, not just a hypothetical C1 gate.
-
---
-
-## Summary for the C1 contract
-
- **Writer count**: 6 confirmed call sites of `RuntimeEntityRecord.SetPhysicsBody`
-  across 3 files (`RuntimeEntityDirectory.cs:359`,
-  `RuntimeEntityObjectLifetime.cs:766`,
-  `RuntimeLocalPlayerPhysicsPublicationState.cs:405,1025`,
-  `RuntimePhysicsState.cs:1558,1666`) — plus a probable 7th App-side ad hoc
-  projectile body-construction site not yet traced to a canonical writer
-  (flagged, out of local-player scope).
- The dormant `RuntimeLocalPlayerPhysicsPublicationState` +
-  `RuntimeSetPositionState`'s ~15 dormant-activation methods already
-  implement essentially the COMPLETE Option 2 transaction (off-canonical
-  prepare against a scratch clock/sealed candidate controller, single
-  validated atomic commit, full retail-staged SetPosition activation) with
-  epoch/token/generation/identity re-validation at every external entry
-  point — it has ZERO production callers in either host.
- The single largest remaining defect even AFTER wiring: the public
-  `RuntimeLocalPlayerMovementState.Controller` setter is an unguarded escape
-  hatch both hosts currently use directly; it must be sealed (made
-  unreachable from hosts, or itself epoch-gated) for the word "exclusive" in
-  prerequisite C to be true.

-# Next-agent prompt — finish the retail placement/collision campaign
-
-Continue acdream from the 2026-08-03 stabilization checkpoint. The code is
-modern; behavior must remain retail-faithful. The campaign is playable again,
-but it is **not closed**.
-
-## Start here
-
-Use the merged local `main` worktree:
-
-```text
-C:\Users\erikn\source\repos\acdream
-```
-
-The completed fixes originated on `codex/port-claude-agents` and are merged
-into local `main`. Confirm the exact starting commit with `git rev-parse HEAD`
-and read the operator's handoff message for the merge SHA. Do not reset,
-clean, or overwrite the main worktree's untracked research/reference files.
-The original feature worktree remains at:
-
-```text
-C:\Users\erikn\.codex\worktrees\af5e\acdream
-```
-
-That feature worktree contains protected user-local modifications and is not
-the preferred continuation workspace.
-
-Read these files in order before editing:
-
-1. `CLAUDE.md` and `AGENTS.md`.
-2. `docs/plans/2026-08-02-placement-cutover.md` — canonical placement-cutover
-   plan and the 2026-08-03 checkpoint.
-3. This prompt.
-4. `docs/research/2026-08-02-collision-throughput-handoff/implementer-progress.md`
-   — especially `## P1` and the final stabilization checkpoint.
-5. `docs/research/2026-08-02-collision-throughput-handoff/p1-retirement-receipt-loop.md`.
-6. `docs/research/2026-08-02-c3c-cutover-closeout.md`.
-7. `docs/ISSUES.md` #269 and #276–#280.
-8. `docs/architecture/retail-divergence-register.md` rows AP-1, AP-22,
-   AP-131, AD-1, AD-10, AD-60, and TS-28.
-
-`docs-drafts.md` is now explicitly historical. Do **not** apply it wholesale:
-it predates the final fixes and incorrectly tries to reuse issue number #280.
-
-## Binding rules
-
- Grep `docs/research/named-retail/acclient_2013_pseudo_c.txt` by named
-  `class::method` before fresh decompilation. Retail behavior is the oracle.
- Preserve the modern Runtime-owned, presentation-independent architecture.
-  Graphical and headless hosts must use the same canonical gameplay owners.
- Root causes only. Do not add timeouts, grace periods, suppression flags,
-  catch-and-swallow paths, duplicated placement writers, or compatibility
-  bypasses to make a test green.
- The user's connected observations are acceptance facts. A green automated
-  test cannot overrule a live regression.
- Never use `git add -A`, `git add .`, `git reset --hard`, or
-  `git checkout -- <path>`. Stage exact paths only.
- Do not delete or normalize unrelated/untracked worktree content.
- Each independent fix must be a bisectable commit whose message records the
-  root cause and evidence.
- Update the divergence register and issues in the same commit that changes
-  their truth. Retire a row only when its exact legacy mechanism is gone.
- Do not push unless the user explicitly asks.
- Connected tests require the user's ACE server at `127.0.0.1:9000`. Close
-  the client gracefully before reconnecting so ACE releases the session.
-
-## What has been completed
-
-### C3c and collision-publication checkpoint
-
- `529e0e9d` — C3c production first-entry cutover for graphical and headless
-  hosts.
- `71604331` — O(changed) per-landblock collision publication checkpoint.
-  Its original commit was deliberately marked WIP after the first feel test;
-  do not treat that old label as the current product status. The following
-  fixes addressed the observed failures.
-
-### Stabilization fixes, all user-verified where visual behavior applies
-
-1. `01f4791e` — **retirement-receipt replay loop fixed.**
-   - Root cause: a pending-only live-projection bucket was promoted to a
-     second full landblock cleanup receipt after the first detach had already
-     committed. The duplicate guard threw; a broad resumable path replayed
-     the detach 243 times.
-   - Fix: retain pending identities without manufacturing another receipt;
-     post-commit receipt invariants are terminal, not resumable.
-   - Evidence: focused recenter tests; complete Release suite 10,815 passed /
-     4 skipped; lifecycle report
-     `logs/connected-world-gate-20260802-203751/report.json`; nine-stop report
-     `logs/connected-r6-soak-20260802-204309.report.json` with `Passed=true`,
-     nine checkpoints, zero failures, zero wait cues, zero pending
-     retirements, and no recurrence of the 243x exception.
-
-2. `670f307c` — **remote placement and targeting share one world frame.**
-   - Root cause: CreateObject positions are landblock-local, but Runtime
-     submitted remote first-entry placement with zero world offset; the local
-     physics host also published a landblock-local origin to targeting.
-   - Fix: Runtime owns the accepted local-player world center, converts remote
-     Create placement before SetPosition, and publishes the local body's world
-     position.
-   - User gate: monsters and statics place correctly; monsters chase and hit
-     the visible player instead of attacking another coordinate.
-
-3. `1fc529cd` — **distant Use/approach restored.**
-   - Root cause: Runtime object lookup is intentionally non-constructing, so a
-     static door/corpse could enter MoveTo without a physics host and its
-     target snapshot expired at the origin. Startup placement could also
-     leave an impossible pre-PartArray motion suffix ahead of later actions.
-   - Fix: ensure the canonical minimal static host before routing MoveTo and
-     reconcile the startup suffix exactly at presentation attach.
-   - User gate: near and distant object use works, including approach, turn,
-     and use after arrival.
-
-4. `f24532ad` — **spell, recall, projectile, and static VFX binding fixed.**
-   - Root cause: C3c could create effect/projectile/static-animation sidecars
-     before first SetPosition had bound the entity's mesh, pose, cell, and
-     visibility. One-shot F754/F755 packets were lost and projectiles could
-     inherit a cell-less body.
-   - Fix: exact-incarnation presentation barrier and FIFO replay; retry
-     projectile/static binding on the committed visibility edge; synchronize
-     effect cells on rebucket.
-   - User gate: buffs/protections, recall effects, arrows, combat spell
-     projectiles, portals, and static animation all work.
-
-5. `175ad6b0` — **login materialization acknowledgement fixed.**
-   - Root cause: ACE creates the local player Hidden and releases that state on
-     LoginComplete. Sending LoginComplete from raw F746 receipt raced first
-     canonical placement and left the purple haze over the character.
-   - Fix: one completion callback from Runtime's local first-entry terminal
-     edge; content-less headless retains its only truthful accepted-Create
-     edge.
-   - User gate: ordinary login no longer leaves the purple haze; recall still
-     has the intended materialization presentation.
-
-### Latest focused verification
-
-After the final fix, these passed:
-
- 90 focused App effect/projectile/static-animation scheduler tests.
- Two focused Runtime login-completion tests.
- The exact live-entity cell-tracking regression.
- All 79 Headless tests.
- `dotnet build AcDream.slnx -c Release --no-restore` with zero errors
-  (existing warnings remain).
-
-The long complete suite and connected nine-stop soak were **not rerun after
-the final four stabilization commits**. The P1 soak proves P1's binary, not
-the final campaign binary.
-
-## What remains — execute in this order
-
-### 1. Reconcile the six selected-fixture failures
-
-A broad selected run after cleanup exposed:
-
- five failures in `LiveEntityRuntimeTests`, associated with the still-open
-  placement/cell cutover;
- one old `RuntimeLiveEntitySessionControllerTests` remote-first-entry fixture
-  that provides an empty collision source while the production contract now
-  requires truthful collision admission.
-
-Re-run these two classes first and record the exact test names and assertions.
-Classify each as either a real product failure or a stale fixture. If stale,
-update the fixture to provide the same valid prepared collision neighborhood
-as production; never weaken the product contract or merely change expected
-values. If real, fix the owning production mechanism and add a smaller
-regression test.
-
-Suggested first commands:
-
-```powershell
-$env:ACDREAM_PAK_PATH='C:\Users\erikn\Documents\Asheron''s Call\acdream.pak'
-dotnet test tests/AcDream.App.Tests/AcDream.App.Tests.csproj -c Release --no-restore --filter FullyQualifiedName~LiveEntityRuntimeTests -m:1
-dotnet test tests/AcDream.Runtime.Tests/AcDream.Runtime.Tests.csproj -c Release --no-restore --filter FullyQualifiedName~RuntimeLiveEntitySessionControllerTests -m:1
-```
-
-### 2. Finish C4: remaining authoritative placement routes
-
-The plan still marks routes 2–7 open:
-
- route 2: ForcePosition;
- route 3: portal placement through `RuntimeWorldTransitState` and
-  `RuntimePortalPlacementAuthority`;
- route 4: remote Create/Position, deleting the remaining
-  `RemoteTeleportController`/inline MoveOrTeleport duplicate;
- route 5: authoritative projectile correction;
- route 6: drops and split-recovery marking;
- route 7: pickup, parent-detach, and delete/recreate residue.
-
-Inventory every current writer before editing. For each route, prove:
-
- one Runtime SetPosition transaction owns accepted frame, exact cell,
-  collision result, shadow/workset membership, and deferred-cell lifetime;
- App only projects the committed result;
- graphical and headless hosts use the same command and state path;
- stale sequences, delete/GUID reuse, missing cells, portal generations, and
-  replacement collision generations cannot commit old state;
- no route reconstructs from a stale spawn or uses the legacy outdoor demote/
-  terrain-Z lift.
-
-Resolve #276 when the spawn settler's resolved `CellId` becomes authoritative.
-Resolve #277 with a real service-window/celless lifecycle instead of relying
-on ACE's current broadcast radius.
-
-### 3. Fix #280: destination prefetch before portal reveal
-
-Current behavior waits only a hard-coded radius-one (3x3) outdoor
-neighborhood, while the visible configured world extends farther. The user
-can see distant terrain continue building after portal exit.
-
-Port the retail mechanism, not a larger magic number:
-
- `CellManager::PreFetchCells @ 0x00455820`;
- `LScape::PreFetchCells @ 0x00505660`;
- `CLandBlock::PreFetchCells` and `CLandBlockInfo::PreFetchCells`;
- `SmartBox::UseTime @ 0x00455410` while `blocking_for_cells`;
- the `TAS_TUNNEL_CONTINUE` resume/reveal order.
-
-Use the quality/view-distance configured destination window. Hold one
-generation-scoped reservation across terrain, buildings/statics, EnvCells,
-render publication, composite textures, and collision. Keep portal UI and
-wait cue responsive. Never reveal early because of a timeout, and do not wait
-for an impossible terminal marker for all dynamic ACE objects.
-
-Acceptance: repeated login, `/ls`, spell recall, and portals at every quality
-setting reveal no constructing terrain, missing nearby statics/buildings,
-unready interiors, missing composites, or absent nearby collision. Dynamic
-monsters/items may still arrive later from ACE.
-
-### 4. C5 closeout and live gates
-
-After steps 1–3:
-
-1. Delete every superseded placement writer and compatibility projection.
-2. Run focused Runtime/Core/App tests for every route.
-3. Run the complete Release solution suite with the installed pak.
-4. Run the exact lifecycle/reconnect route.
-5. Run the canonical nine-stop soak on the **final binary**. Read
-   `report.json`, not marker output. Required: `Passed=true`, zero failures,
-   every canonical checkpoint, `waitCueShown=false`, zero pending
-   publication/retirement/reveal debt, graceful exit, and no render-shadow
-   mismatch. Diagnose any real failure; do not rerun past it.
-6. Perform two-client observation for remote creation, chase/attack, doors,
-   drops/pickups, portal departure/arrival, arrows, and spells.
-7. Ask the user for the remaining #269/#278 slope-glide comparison at the
-   known impassable slope.
-
-Only then retire AP-1, AD-1, AP-131, and the legacy half of AD-60 and close
-the corresponding placement issues.
-
-### 5. Finish the original physics-divergence campaign
-
-After placement C5 is green:
-
- **AP-22:** make `ShadowShapeBuilder` the sole authority for authored Setup
-  collision shapes. Preserve cylinder order; use authored spheres when there
-  are no cylinders; cylinder-first for mixed data; truly shapeless means no
-  shadow. Remove invented `Setup.Radius` cylinders, `Radius * 2` heights, and
-  sphere-to-cylinder coercion across graphical, headless, static, and live
-  paths.
- **AD-10:** prove remote motion uses the full transition sweep, remove
-  terrain-normal preprojection, and let `CTransition::adjust_offset` project
-  against the actual retained contact plane. Preserve interpolation,
-  correction replacement, Hidden state, and network cadence.
- Run the final movement/collision matrix and update the divergence ledger,
-  architecture, roadmap, milestones, memory, `CLAUDE.md`, and `AGENTS.md`.
-  Resume vendor Slice 5 only after this campaign is genuinely closed.
-
-## Required deliverable
-
-For every remaining item report:
-
- observed failure and deterministic reproduction;
- retail/reference evidence with named functions and addresses;
- root cause in plain language plus file/line evidence;
- exact fix and why it preserves Runtime ownership;
- tests added or corrected;
- commit SHA;
- complete build/test/connected-gate numbers;
- user visual result where required;
- divergence/issue rows retired, narrowed, or left open.
-
-Finish with an explicit list of anything still open. Do not describe the
-campaign as complete while any C4 route, #280, final-binary soak, AP-22,
-AD-10, or required user visual gate remains.

-# O(changed) collision clone — design note
-
-**Phase:** research + design only. No production edits, nothing staged, no probes left
-behind. Worktree `C:\Users\erikn\.codex\worktrees\af5e\acdream`, branch
-`codex/port-claude-agents`, HEAD `c52ce14a`.
-
-**Problem:** the collision-generation staging clone is O(resident world) per landblock
-publication, so loading an N-landblock ring costs O(N²). The far ring never converges.
-C3c made it user-visible (late monster pop-in, extended/stuck portal space, portal-exit
-pop-in, failing nine-stop soak) but did not cause it.
-
---
-
-## (a) What the one-leaf-per-step invariant actually protects
-
-### It is a frame-time bound. Nothing else.
-
-The whole-world copy did not arrive with `6b28ff99`. It arrived one commit earlier, in
-`be94bc9b` "fix(physics): activate collision generations atomically" (2026-07-31), as a
-**synchronous** copy performed in a single call at admission:
-
-```csharp
-// be94bc9b, PhysicsEngine.CreateCollisionStagingCopy
-foreach ((uint id, LandblockPhysics landblock) in _landblocks)
-    staging._landblocks[id] = landblock;
-staging.ShadowObjects.CopyCollisionStateFrom(ShadowObjects, stagingCache);
-```
-
-`6b28ff99` "make collision activation starvation-free" replaced that with
-`CollisionStagingBuilder` (`src/AcDream.Core/Physics/PhysicsEngine.cs:785-941`), which
-performs the *same* copy chopped into single leaves across frames. The retired AD-6 row
-states the purpose verbatim
-(`docs/architecture/retail-divergence-register.md:113`):
-
-> "Admission captures the active root in O(1); a stable landblock/owner slot suffix
-> materializes non-target leaves incrementally, **so resident-world size cannot become a
-> synchronous clone spike**."
-
-The committed test says the same thing three ways
-(`tests/AcDream.Runtime.Tests/Physics/RuntimePhysicsStateTests.cs:921-991`):
-
-| Assertion | line | What it pins |
-|---|---|---|
-| `Assert.InRange(admissionAllocation, 1L, 128L*1024L)` | :973 | admission allocates a constant |
-| `Assert.Equal(0, prepared.Engine.LandblockCount)` | :974 | admission copies no resident landblock |
-| `Assert.InRange(step.WorkUnits, 0, 1)` | :983 | **the copy is chopped to one leaf per host step** |
-| `Assert.True(advances > residentLandblocks)` | :988 | it really walked the resident world |
-| `Assert.Equal(residentLandblocks, prepared.Engine.LandblockCount)` | :989 | the draft ends up holding the whole world |
-
-So the invariant protects **hitch avoidance**: a dense resident world must not produce
-one long synchronous copy inside a single update step. It is a *scheduling* property
-asserted as a *mechanism*, which is why the batching lever tripped it.
-
-### What it does NOT protect
-
- **Not concurrent-reader isolation.** That is `CollisionWorldStateSlot.TransferTo`'s
-  single `Volatile.Write` (`src/AcDream.Core/Physics/CollisionWorldState.cs:66-84`).
-  And a full threading audit of every writer and reader of `CollisionWorldState` found
-  **no concurrent reader or writer exists**: `GameWindow` runs one Silk.NET loop thread;
-  `UpdateFrameOrchestrator.Tick` runs `_streaming.Tick()` → `DrainAndApply` and then the
-  live/physics/camera phases strictly sequentially on that thread; the only background
-  workers (`LandblockStreamer` worker thread, `EnvCellRenderer` `Parallel.ForEach`,
-  `ObjectMeshManager` `Task.Run`) never touch `PhysicsDataCache` / `CellGraph` /
-  `ShadowObjectRegistry` / `PhysicsEngine` — grep of `LandblockBuildFactory.cs` and
-  `LandblockMesh.cs` for those types returns zero hits. Every one of
-  `BeginCollisionAdmission` (:2040), `PrepareCollisionGeneration` (:2092),
-  `AdvanceCollisionGenerationPreparation` (:2123), `StageCollisionAssets` (:2218),
-  `AdvanceCollisionGenerationSeal` (:2298), `CommitCollisionGeneration` (:2382),
-  `CancelCollisionGeneration` (:2139) passes through
-  `RuntimePhysicsState.EnsureCollisionMutationThread` (:2857-2869). The
-  `ConcurrentDictionary` choices are load-bearing only for *single-threaded*
-  mutate-while-enumerating (`PhysicsDataCache.cs:958-984`, and the seal cursor holding a
-  live enumerator across frames at :1081-1160) — the cross-thread rationale in the
-  `CellGraph.cs:17` and `PhysicsDataCache.cs:14-20` doc comments is **stale after
-  6b28ff99**.
- **Not admission fairness.** That is the separate journal/coalescing machinery
-  (`RuntimePhysicsState.cs:475-529`, research doc step 5) — the other half of what
-  "starvation-free" meant. It is orthogonal to the leaf metering and stays.
-
-### What the pre-6b28ff99 mechanism did
-
-`be94bc9b`'s commit was a **delta apply**, not a root swap:
-
-```csharp
-// be94bc9b, PhysicsEngine.CommitLandblockReplacement — deleted by 6b28ff99
-DataCache.CommitLandblockReplacement(replacement.DataCache);   // O(changed)
-_landblocks[replacement.LandblockId] = replacement.Landblock;
-ShadowObjects.CommitLandblockReplacement(replacement.Shadows);
-```
-
-`6b28ff99` replaced those three lines with
-`stagingCache.CollisionWorld.TransferTo(activeCache.CollisionWorld)`
-(`PhysicsEngine.cs:304-321`). **That is the change that made the clone load-bearing.**
-Before it, the clone was a build sandbox; after it, the clone *is* the world that gets
-published, so every leaf not cloned is a leaf deleted from the world.
-
-Before `be94bc9b` the client mutated the active maps in place across many frames — the
-genuinely non-equivalent state the research doc describes ("the active `PhysicsDataCache`,
-`CellGraph`, `PhysicsEngine`, buildings, static shadows, and retained-object refloods
-changed at different cursors", `docs/research/2026-07-31-atomic-collision-generation.md:12-16`).
-**The atomicity requirement is "the multi-frame build must not be observable", not "the
-whole world must be swapped".** A delta applied inside one synchronous update-thread call
-satisfies it.
-
-### The cost is worse than F4 measured
-
-F4 attributed median 19,736 / p90 32,135 / max 38,021 leaves and median 3.64 ms per
-publication to the staging clone. The **seal** does the same walk again: the replacement
-builder holds live enumerators over four `_staging` maps *and* four `_active` maps
-(`PhysicsDataCache.cs:1081, 1092, 1103, 1114, 1125, 1136, 1147, 1158`) plus two in
-`CellGraph.cs:184, 203`, using `CapturePrefixOne` / `CaptureRemovalOne` — a full scan of
-each map to find O(target) keys. Real per-publication cost is therefore roughly **2–3×
-resident world**, not 1×. **Fixing only the clone leaves O(N²) in the seal.** Any design
-that does not also scope the removal capture is not a fix.
-
---
-
-## (b) Candidate designs
-
-### D1 — Structural sharing (persistent/immutable `CollisionWorldState`)
-
-Replace the ~20 mutable maps with persistent maps (HAMT / `ImmutableDictionary`) so a
-staging clone shares unchanged subtrees and copies only the changed path.
-
- **Blast radius:** every read and write site of every map in `CollisionWorldState`,
-  `PhysicsDataCache`, `CellGraph`, `ShadowObjectRegistry`, `PhysicsEngine`.
- **Invariant changes:** none semantically; the root swap survives unchanged, so the
-  atomicity story is untouched.
- **Throughput:** admission O(1), clone O(1), commit O(changed · log N). Excellent on the
-  copy axis.
- **Why rejected:** it pays for the copy with the *query*. A HAMT probe is several times a
-  `Dictionary` probe and allocates on write; the resolver runs thousands of these per
-  frame at 30 Hz. Slice I's entire thesis is flat, integer-indexed, zero-allocation
-  collision (`docs/plans/2026-07-25-modern-runtime-slice-i.md`; I1 measured 0 B/resolve).
-  D1 optimizes the rare operation at the expense of the hot one and fights the I-series
-  architecture head-on.
-
-### D1b — Landblock-sliced root (per-prefix immutable slice + small map)
-
-Regroup the root so each landblock's cells / flat cells / EnvCells / buildings / terrain /
-outdoor cells / `LandblockPhysics` live in one immutable `LandblockCollisionSlice`, and
-the root becomes `Dictionary<prefix, slice>` (~625 entries). Commit = one dictionary
-write per prefix.
-
- **Blast radius:** every keyed read becomes mask + two probes; the seal's removal scans
-  collapse to "old slice vs new slice". The **shadow registry does not partition** —
-  `ShadowEntityCells`, `ShadowEntityShapes`, `ShadowEntityRegistrations`,
-  `ShadowOwnerVersions` are owner-keyed and owners legitimately span prefixes (that is
-  the whole retained-owner problem), so the shadow half needs a separate mechanism.
- **Invariant changes:** the atomic unit becomes the slice; the root swap disappears.
- **Throughput:** O(changed) by construction, and atomic even for a hypothetical
-  concurrent reader.
- **Verdict:** this is the right answer *if* concurrent readers existed. They do not.
-  Keep it on the shelf as the migration target should the runtime ever go multi-threaded;
-  do not pay its refactor cost now.
-
-### D2 — Per-landblock atomic unit: restore the delta apply *(recommended)*
-
-`CommitLandblockReplacement` drains the **already-existing**
-`PhysicsEngine.LandblockReplacementApplyCursor` (`PhysicsEngine.cs:568-777`) against the
-**active** root inside one synchronous call, instead of `TransferTo`. The staging root
-becomes empty-at-admission (target content only); `CollisionStagingBuilder` phases 0–8 are
-deleted.
-
-The delta record already exists and is already tested: `PreparedPhysicsDataCacheLandblock`
-(`PhysicsDataCache.cs:1255-1270`) is exactly lists of key/value pairs to install and lists
-of ids to remove, all target-scoped. The apply cursor already handles removals, installs,
-terrain, the 0x40 synthesized outdoor cells, the landblock itself, and yields the reflood
-owner ids to the caller at phase 12 (`PhysicsEngine.cs:702-712`). Today it is used to
-rebase a committed peer delta into a *later draft*; pointing its `destination` at the
-active engine is a constructor argument, not new machinery.
-
-**What breaks, honestly:**
-
-1. *Readers mid-query* — nothing. Single-threaded, evidenced above. A drained cursor
-   inside one call is indivisible with respect to every reader that exists.
-2. *Re-entrancy* — real, and the audit flagged it: `OwnerMutated` /
-   `OwnerPrefixMembershipChanged` (`ShadowObjectRegistry.cs:86-87`) can fire mid-delta.
-   Precedent already exists: the commit brackets itself with
-   `_suppressCollisionOwnerJournal = true` (`RuntimePhysicsState.cs:2491-2501`). Extend
-   that bracket to cover the whole apply.
-3. *Cross-frame enumerators* — the seal holds live enumerators over the **active** maps
-   across frames (`PhysicsDataCache.cs:1092, 1136, 1158`). A delta apply now mutates the
-   maps those enumerators walk. `ConcurrentDictionary` will not throw, but the observed
-   set is unspecified. **O1 below removes those enumerators entirely**, which is why O1
-   must land first.
-4. *The retirement machinery* — `LandblockRetirementCursor` (`PhysicsEngine.cs:348-...`)
-   currently retires from an off-side draft. Same cursor, destination becomes the active
-   root, still drained in one call.
-5. *The reflood context* — the seal currently computes retained-owner refloods against a
-   full staging world. With an empty staging root that context is gone, so the reflood
-   moves to the commit call, against the now-current active world. **That is precisely
-   retail**: `CObjCell::init_objects` (0x0052B420) → `CPhysicsObj::recalc_cross_cells`
-   (0x00515A30), already the retail anchor cited on the AD-6 row.
-6. *The peer-rebase / journal apparatus* — with no snapshot there is nothing to rebase.
-   `EnqueueCommittedRebase` (`RuntimePhysicsState.cs:563-578, 2502-2507`) and most of the
-   journal become dead. Delete them in the same slice; do not leave dead invariants
-   guarding a deleted mechanism.
-
- **Throughput:** per publication ≈ target payload (~70–200 leaves at the measured
-  ~184 ns/leaf) + the owners touching the target, versus today's ~2–3 × 20,000. Roughly
-  **300× less work per publication**, and — decisively — **independent of resident-world
-  size**, so total ring load goes O(N²) → O(N). At the failing run's numbers that is
-  ~13.7 M leaf copies for a 625-landblock ring down to ~44 K.
-
-### D3 — Adjacency-scoped clone (the tempting middle ground) — **rejected as unsafe**
-
-Copy only leaves in the target's 3×3 landblock neighbourhood. One predicate change in
-`CopyOneOutsideTarget` (`PhysicsEngine.cs:949-961`); clone drops ~20,000 → ~630 and
-becomes O(1) in world size.
-
-Rejected for a structural reason worth stating plainly: **while commit is a whole-root
-transfer, "clone less" means "delete more."** Anything not copied into the draft is absent
-from the root that replaces the world. A partial clone is therefore a silent world-erasure
-bug, not a perf tuning knob. Only after commit becomes a delta does bounded context become
-safe — at which point D2 has already removed the need for it. It also leaves the seal's
-O(world) scans untouched, so O(N²) survives regardless.
-
---
-
-## (c) Recommendation
-
-**Take D2, in three landable slices, with O1 first.**
-
-Rationale in one line: the delta-apply commit path is not a new invention — it is the
-mechanism that shipped in `be94bc9b` and was deleted by `6b28ff99` to buy an atomicity
-guarantee against concurrent readers that do not exist; restoring it makes the cost
-O(changed) by construction and moves the client *toward* retail's `init_objects` shape,
-not away from it.
-
-### Invariant-test replacement
-
-Delete from `DenseResidentWorldAdmissionIsConstantAndMaterializesOneLeafPerStep`
-(`tests/AcDream.Runtime.Tests/Physics/RuntimePhysicsStateTests.cs:921-991`) the three
-assertions that pin the clone itself — `:983` `Assert.InRange(step.WorkUnits, 0, 1)`,
-`:988` `Assert.True(advances > residentLandblocks)`, `:989`
-`Assert.Equal(residentLandblocks, prepared.Engine.LandblockCount)`. They assert the exact
-mechanism being removed.
-
-Replace with `CollisionPreparationCostIsIndependentOfResidentWorldSize` — a strictly
-stronger invariant, because it pins the *property* (bounded, world-size-independent work)
-rather than a mechanism:
-
-```
-Run the full admission → preparation → seal → commit sequence twice,
-at residentLandblocks = 32 and residentLandblocks = 256.
-
-Assert total preparation advances(32) == total preparation advances(256)   // O(changed)
-Assert total seal WorkUnits(32)      == total seal WorkUnits(256)          // closes the seal scans
-Assert every step.WorkUnits <= K                                           // K = retained per-step bound
-Assert admissionAllocation in [1, 128 KiB]                                 // kept from :973
-Assert prepared.Engine.LandblockCount == 0 after preparation completes     // stronger than :974:
-                                                                           // the draft now holds ONLY the target
-```
-
-Add two more:
-
- `CommitAppliesOneLandblockDeltaInASingleCall` — the engine-mutating
-  `CommitCollisionGeneration` call drains the apply cursor to `Completed` before it
-  returns; the active world holds no target-prefix content before it and the complete
-  target after it, with no observable intermediate.
- `CommitTimeRefloodMatchesPrecomputedReflood` — for a fixed scenario, the owner set and
-  each owner's resulting cross-cell set after a commit-time reflood are **equal** to what
-  the pre-change staged reflood produced. This is the proof that D2 is a scheduling
-  change and not a semantics change, and it is the test that makes the perf framing in
-  (d) legitimate.
-
-**Keep unchanged:** every `Assert.InRange(seal.WorkUnits, 0, 1)` at `:558, :667, :747,
-:848, :1797, :2020, :2318, :2428, :3033` — the seal stays metered; the zero-managed-byte
-commit assertions (the delta lists are built during seal, so the apply must still be
-allocation-free); and `CommittedPreparationRevokesItsStagingCollisionRoot` (`:1664`) in
-spirit — the staging root must still be revoked after commit, it simply no longer becomes
-the active root.
-
-### Migration plan
-
-| Slice | Change | Gate |
-|---|---|---|
-| **O1** | Per-prefix installed-key ledger in `CollisionWorldState`, maintained by the install/remove paths. Rewrite the seal's ten full-map scans (`PhysicsDataCache.cs:1081-1160`, `CellGraph.cs:184, 203`) to enumerate that set. Removes the cross-frame active-map enumerators. **Behaviour-identical; a pure win that lands alone.** | existing suites green + the new seal-independence assertion |
-| **O2** | `PhysicsEngine.CommitLandblockReplacement` drains `LandblockReplacementApplyCursor` against the active root instead of `TransferTo`. Extend the `_suppressCollisionOwnerJournal` bracket over the whole apply. Retirement cursor destination → active root. | focused Runtime physics suite + connected lifecycle gate |
-| **O3** | Empty staging root: delete `CollisionStagingBuilder` phases 0–8. Move retained-owner reflood into the commit call (retail `init_objects` → `recalc_cross_cells`). Delete the now-dead peer-rebase/journal paths and their tests. | full ladder below |
-
-### Gate ladder (O3 closeout)
-
-1. **Focused:** Runtime physics collision-generation suite, App
-   `LandblockPhysicsPublisherTests`, Headless `HeadlessSessionHostTests`.
-2. **Complete Release solution:** baseline to match or beat is **10,808 passed / 0 failed
-   / 4 skips** (`-m:1`, `ACDREAM_PAK_PATH`).
-3. **Connected lifecycle/reconnect gate:** signature must hold — `Passed=true`,
-   `Failures=[]`, both sessions `ExitCode=0`, zero render-shadow mismatches, zero pending
-   deltas, graceful exits.
-4. **Nine-stop soak must reach `Passed: true` with `Failures: []`.** The failing run is
-   `logs/connected-r6-soak-20260802-143157.report.json` (37 failures, `Passed: false`);
-   the passing baseline is `logs/connected-r6-soak-20260727-004942.report.json`
-   (`Passed: true`, commit `a9a822f2`). Concrete acceptance, per checkpoint:
-
-   | Key | Failing run | Required |
-   |---|---|---|
-   | `resources.streamingWork.deferredCompletions` | 92–501 at 8/9 stops | `0` at all 9 |
-   | `resources.streamingWork.farBacklog` | same values | `0` at all 9 |
-   | `resources.streamingWork.pendingPublications` | `1` at 8/9 | `0` at all 9 |
-   | `resources.streamingWork.deferredAdoptedCpuBytes` | 1.5–8.5 MB | `0` at all 9 |
-   | `resources.streamingWork.oldestDeferredAgeMilliseconds` | 37,764–69,728 | `0` |
-   | `resources.loadedLandblocks` | 124–533 | **625** at the eight outdoor stops |
-   | `reveal.waitCueShown` | `true` at 6/9 | `false` at all 9 — *this is the user-reported "extended/stuck portal space"* |
-   | `streamingWork.lifetimeFrameOverrunCount` | 1,706 | materially lower |
-   | `streamingWork.maximumOperationStage` | `"publication-index-physics"` | must no longer name this stage |
-
-   **`aerlinthe` (sequence 4) is the control, not a target.** It is the one indoor
-   destination and the one stop that is already clean in the failing run (374/173 vs the
-   baseline's 374/176, every streaming counter `0`) — precisely because an indoor
-   destination streams few landblocks, so O(N²) never bites. It must stay clean; do not
-   expect it to reach 625.
-
-5. **Frame time must not regress — and must recover.** Route-level `cpuUs` from
-   `frame-history-summary.json`, microseconds:
-
-   | | p50 | p95 | p99 | p999 |
-   |---|---|---|---|---|
-   | baseline `20260727` | 9,730 | 41,262 | 44,875 | 63,474 |
-   | failing `20260802` | 17,001 | 47,434 | 57,061 | 102,876 |
-
-   Gate on the sharper per-checkpoint window numbers: **`checkpointWindows[].metrics.cpuUs`
-   p99 within +10 % of the `20260727` baseline at every stop.** The worst offenders are
-   `caul-plateau` 101,408 → target ≈ 47,821; `caul-return` 103,309 → ≈ 46,938;
-   `caul-baseline` 108,148 → ≈ 43,664; `sawato-baseline` 49,748 → ≈ 10,592. Frame count
-   should recover toward the baseline's 35,492 frames / 498.5 s from the failing run's
-   25,965 / 583.9 s.
-
-6. **Do NOT gate on these — retest only after convergence.** `trackedGpuBytes` (62 MB
-   failing vs 474 MB baseline), `meshRenderData` 588 vs 607, `meshEstimatedBytes`
-   233.8 MB vs 268.6 MB, and the inverted CPU mesh-cache hit ratio
-   (3,666 hits / 5,689 misses vs 20,825 / 6,845) are all far-ring-never-converged
-   artifacts of the same mechanism. F4 already reached this conclusion; a leak
-   investigation before convergence is restored will chase a ghost.
-
-### Register / plan bookkeeping (same commit as the code)
-
- **`docs/architecture/retail-divergence-register.md:113`** — the retired AD-6 row
-  describes the deleted mechanism verbatim ("one shared off-side `CollisionWorldState`",
-  "one zero-managed-byte volatile root transfer", the journal, the peer rebases). A
-  retired row still documents what shipped; leaving it describing a deleted clone is
-  exactly the out-of-sync failure the register rules forbid. Rewrite it to the delta-apply
-  mechanism. The row's retail anchor is already
-  `CObjCell::init_objects` → `recalc_cross_cells` (0x0052b420 / 0x00515a30) — the new
-  mechanism is **closer** to that anchor, so no new deviation row is created.
- **Judgment call for the implementer, do not assume:** the *original* AD-6 deviation was
-  "Per-LANDBLOCK shadow re-flood on hydration vs retail per-CELL `recalc_cross_cells`"
-  (`be94bc9b` register diff). If O3's commit-time reflood is again per-landblock rather
-  than per-cell, decide explicitly whether AD-6 must be un-retired or a successor row
-  added, and record the decision. Flagged, not decided here.
- **`docs/research/2026-07-31-atomic-collision-generation.md`** — steps 2, 3, 5, 6, 7, 8
-  and most of the "Deterministic evidence" list describe the clone / journal / rebase.
-  Rewrite in the same commit.
- **`memory/project_collision_port.md`** — the 37-line block `6b28ff99` added is now wrong.
- **`claude-memory/project_physics_collision_digest.md`** — add two DO-NOT-RETRY entries:
-  (1) *"Do not re-introduce a whole-world staging clone. The atomic unit is the landblock
-  delta applied in one update-thread call; the runtime is single-threaded and the root
-  swap buys nothing."* (2) *"Batching N leaves per staging step is not a fix — measured
-  1.8× at N=256, not convergence, and it trips the committed invariant test."*
- **`docs/ISSUES.md`** — F4 established this regression is not in the C3c diff, so it
-  needs its own issue id (the C3c smoke-test commit `c52ce14a` filed #279 for a different
-  finding). File it, and reference it from the O1/O2/O3 commit messages.
- **Rollback:** each slice lands as one commit with its own recorded `git revert` SHA,
-  per the Modern Runtime convention.

-
-## (d) Perf-work framing
-
-**This is modern-runtime infrastructure, not retail-scoped behaviour work.** The delta
-apply installs the *identical* `PreparedPhysicsDataCacheLandblock` content that
-`TransferTo` publishes today — the same cells, flat cells, EnvCell topology, buildings,
-terrain, synthesized outdoor cells, landblock, and owner set. Only the path by which that
-content reaches the active root changes, and only the amount of work done to get there.
-Collision results, contact planes, walkable polygons, membership, and therefore game feel
-are bit-identical.
-
-The project's render-perf-not-faithfulness-gated rule
-(`claude-memory/feedback_render_perf_not_faithfulness_gated.md`) applies: throughput work
-that is pixel- and feel-identical does not need a retail-behaviour gate. But because this
-is collision, the acceptance bar is still the connected gates plus the user's visual pass
-— green unit tests prove nothing about a streaming convergence bug.
-
-Two guards keep the framing honest:
-
-1. **The direction of travel is toward retail, not away.** Retail hydrates a cell
-   synchronously in `CObjCell::init_objects` and refloods the objects associated with it
-   via `recalc_cross_cells`. A per-landblock delta applied in one update-thread call is
-   the streaming-shaped version of exactly that. The whole-world clone was the adaptation;
-   removing it retires an adaptation rather than adding one.
-2. **The one thing that could change feel is reflood timing** — owners near the target
-   re-flooding at commit rather than from a pre-computed staged set.
-   `CommitTimeRefloodMatchesPrecomputedReflood` (above) is the specific test that turns
-   that from an assumption into evidence. If that test cannot be made to pass, the perf
-   framing is void and the slice needs a behaviour gate.
-
-**Explicitly not a workaround.** Per the no-workarounds rule, note what this is *not*: no
-suppression flag, no grace period, no budget loosening, no early-return guard at the
-symptom. The root cause is an algorithm that is quadratic in resident-world size, and the
-fix is to make it linear by restoring the per-landblock atomic unit the mechanism had
-before `6b28ff99`.
-
-### Measure before and after
-
-A stripped-after probe should count, per publication: (clone leaves, seal leaves, apply
-leaves) and wall-clock for each. F4 measured only the clone (median 19,736 / p90 32,135 /
-max 38,021 leaves, median 3.64 ms, 1,584 preparations = 8.53 s CPU in one 4-minute capped
-session). The seal was never measured and D2 must beat both. Expected after O3: clone
-leaves 0, seal leaves ≈ target payload, apply leaves ≈ target payload, total per
-publication well under 100 µs and flat as the ring fills.

-# Docs-commit drafts — collision publication-throughput fix (O1/O2/O3)
-
-> **HISTORICAL DRAFT — DO NOT APPLY WHOLESALE (2026-08-03).** The O1/O2/O3
-> implementation landed in `71604331` and the user-visible stabilization
-> fixes continued through `175ad6b0`. This draft predates that work, assigns
-> issue number #280 to the collision clone even though #280 now canonically
-> tracks incomplete portal-destination prefetch, and names ledger edits that
-> must be re-audited against the final production tree. It remains only as
-> research evidence. Use `NEXT-AGENT-PROMPT.md`, the campaign plan, and the
-> live divergence register for current work.
-
-Drafted per contract; NOT applied to the repo. Apply in the docs commit after
-code review. Register judgment executed as pinned: AD-6 stays retired with a
-successor note; the residual timing/order compression gets a NEW row (AD-62).
-
---
-
-## 1. `docs/architecture/retail-divergence-register.md`
-
-### 1a. Append to the retired ~~AD-6~~ row (line 113), at the end of column 2
-
-> **Successor note (2026-08-02, collision publication-throughput fix
-> O1/O2/O3):** the whole-world staging clone, the owner-mutation journal, the
-> peer-rebase/retirement cursors, and the zero-managed-byte whole-root
-> transfer this row describes were deleted. The shipped mechanism is now the
-> per-landblock delta commit this row's retail anchor always pointed at:
-> admission captures an O(1) empty target-only staging root
-> (`PhysicsEngine.CollisionStagingBuilder`), the seal enumerates one prefix's
-> installed keys through the `CollisionWorldState` per-prefix ledgers, and
-> `PhysicsEngine.CommitLandblockReplacement` drains the sealed delta into the
-> ACTIVE root in one synchronous update-thread call, recalculating every
-> associated owner's cross-cells against the live world
-> (`ShadowObjectRegistry.ApplyCommittedOwnerReplacement` +
-> `RefloodPrefixOwnersAfterReplacement`; retail `CObjCell::init_objects`
-> 0x0052b420 → `CPhysicsObj::recalc_cross_cells` 0x00515a30). Equivalence is
-> pinned by `CommitTimeRefloodMatchesPrecomputedReflood`; world-size
-> independence by `CollisionPreparationCostIsIndependentOfResidentWorldSize`.
-> Residual timing/order compression vs retail: AD-62.
-
-### 1b. New row AD-62 (residual timing/order compression), adaptation class
-
-| AD-62 | **Adaptation.** Commit-time collision reflood granularity/order: retail runs `CObjCell::init_objects` per CELL at cell hydration and `CPhysicsObj::recalc_cross_cells` per object as each cell loads; acdream runs the equivalent once per LANDBLOCK replacement inside the single synchronous activation call, walking the sealed owner list then the live prefix-owner slots (per-landblock granularity matches the streaming unit, same compression `ShadowObjectRegistry.RefloodLandblock` has always carried). An owner becoming target-associated mid-publication refloods at activation (the prefix-slot sweep) rather than at its own cell's hydration instant; a stationary owner adjacent to the target whose flood would only change through building/EnvCell bridges can carry frame-stale cross-cells between the seal capture and the activation sweep (movers self-heal per `SetPositionInternal`). | `src/AcDream.Core/Physics/PhysicsEngine.cs` (`CommitLandblockReplacement`); `src/AcDream.Core/Physics/ShadowObjectRegistry.cs` (`ApplyCommittedOwnerReplacement`, `RefloodPrefixOwnersAfterReplacement`) | Late/stale cross-cell rows for a non-moving seam object for a few frames around a landblock publication — an object collidable through a wall seam or briefly not collidable where new topology landed | Low | `CObjCell::init_objects` 0x0052b420; `CPhysicsObj::recalc_cross_cells` 0x00515a30; `CPhysicsObj::SetPositionInternal` tail 0x00515330 |

-
-## 2. `claude-memory/project_physics_collision_digest.md` — DO-NOT-RETRY additions
-
-> - **Do not re-introduce a whole-world staging clone for collision
->   generations.** The atomic unit is the landblock delta applied in one
->   update-thread call (`PhysicsEngine.CommitLandblockReplacement`); the
->   runtime is single-threaded and a root swap buys nothing. The clone made
->   ring load O(N²) (the C3c late-monster-pop-in / stuck-portal-space soak
->   failure, issue #280). Deleted 2026-08-02.
-> - **Batching N staging-clone leaves per step is not a fix** — measured 1.8×
->   at N=256, not convergence, and it trips the committed one-work-unit seal
->   invariant. The fix was removing the clone, not tuning it.
-
-## 3. `docs/research/2026-07-31-atomic-collision-generation.md` — update
-
-Add a banner at the top:
-
-> **SUPERSEDED IN PART (2026-08-02).** Steps 2 (whole-world staging clone), 3
-> (owner-mutation journal write-through), 5 (journal coalescing/compaction), 6
-> (peer rebases), 7 (draft retirement cursors), and 8 (whole-root transfer)
-> describe machinery deleted by the collision publication-throughput fix
-> (O1/O2/O3). The atomicity requirement they served — "the multi-frame build
-> must not be observable" — is now met by one synchronous per-landblock delta
-> apply under prefix quiescence with commit-time owner refloods against the
-> live world (retail init_objects → recalc_cross_cells). The admission
-> fairness half (quiescence, prefix mutation permissions, ordered activation)
-> is unchanged and still accurate. Deterministic-evidence entries that name
-> the journal/rebase/retirement tests refer to tests deleted with the
-> machinery; their replacements are
-> `CollisionPreparationCostIsIndependentOfResidentWorldSize`,
-> `CommitAppliesOneLandblockDeltaInASingleCall`, and
-> `CommitTimeRefloodMatchesPrecomputedReflood`.
-
-## 4. `memory/project_collision_port.md`
-
-Remove/replace the 37-line block `6b28ff99` added (the starvation-free clone
-description) with a pointer to the new mechanism (same content as 1a).
-
-## 5. `docs/ISSUES.md` — file the regression as its own issue
-
-> - **#280 — OPEN → fixed pending review: collision staging clone made ring
->   load O(N²)** (filed 2026-08-02). The per-publication whole-world staging
->   clone (be94bc9b synchronous, 6b28ff99 metered) plus the seal's full-map
->   scans cost ~2-3× resident world per landblock publication, so an
->   N-landblock ring cost O(N²) and the far ring never converged. F4 measured
->   median 19,736 leaves / 3.64 ms per publication; C3c made it user-visible
->   (late monster pop-in, extended/stuck portal space, portal-exit pop-in,
->   nine-stop soak failure 20260802-143157) but did not cause it. Fix: O1
->   per-prefix installed-key ledger; O2 per-landblock delta commit
->   (restores be94bc9b's O(changed) apply); O3 empty staging root +
->   commit-time reflood (retail init_objects → recalc_cross_cells) + journal/
->   rebase/retirement machinery deleted. Reference the O1/O2/O3 commits here
->   when they land.
-
-## 6. Milestones/roadmap
-
-No phase-table change needed: this is Modern Runtime infrastructure follow-up
-inside the active campaign context; the C3c smoke-test findings list in
-ISSUES (#278 additions) should get items (d)/(e)/(f)-class re-observed after
-the soak gate passes.
-
-## 7. Commit-message notes for the slice commits
-
- O1: `fix(physics): #280 O1 - per-prefix installed-key ledger; seal scans and
-  landblock removals become O(prefix keys)` — behavior-identical; new test
-  CollisionSealWorkIsIndependentOfResidentWorldSize.
- O2: `fix(physics): #280 O2 - restore per-landblock delta commit (be94bc9b
-  shape) at PhysicsEngine.CommitLandblockReplacement` — notes: staging-slot
-  owner-list widening (direct-staged owners), staging-root revoke, zero-byte
-  commit asserts → O(target payload) bounds (commit-time reflood + dictionary
-  node inserts allocate; world-size independence pinned by the O3 test).
- O3: `fix(physics): #280 O3 - empty staging root; commit-time reflood
-  (init_objects → recalc_cross_cells); delete journal/rebase/retirement
-  machinery` — 9 mechanism tests deleted, 2 contract tests added.

-# Grep sweep — deleted collision machinery (2026-08-02, against the WIP O1-O3 tree)
-
-Produced by an adversarial-review subagent (completed after the review
-round was halted). Verdict summary: the deletions are CLEAN — no
-surviving consumer of the journal/peer-rebase/draft-retirement/staging-
-clone machinery, and no post-`Revoke()` dereference path found. Two
-actionable leftovers and a stale-docs catalog for whoever lands the
-collision work.
-
-## Actionable
-
-1. `CollisionWorldStateSlot.TransferTo` (`CollisionWorldState.cs:270-281`)
-   is fully DEAD — zero callers incl. tests. Delete it (comments at
-   `PhysicsEngine.cs:311/:379` reference it historically and are
-   accurate).
-2. Two test names are stale terminology with live bodies:
-   `RuntimePhysicsStateTests.cs:1730`
-   (`PostCommitOwnerMutationWinsOverQueuedPeerRebase`) and `:2264`
-   (`PendingOrActivePeerRebaseCannotResurrectRetiredLandblock`) — rename
-   when touched.
-
-## Confirmed DEAD (zero refs in src/tests/tools/docs)
-
- `LandblockRetirementCursor`/`Step`/`CreateLandblockRetirementCursor`
- `CollisionStagingBuilder.Advance/.WorkUnits/.Completed/.SuppressLandblock`
- `CopyOneOutsideTarget`
- Owner journal: `_collisionOwnerJournal`, `EnqueueCommittedRebase`,
-  write-through, draft retirement
-
-## Confirmed LIVE (name overlap, different concept — do not "clean up")
-
- `InstallLandblockClone` (`PhysicsEngine.cs:576,673`) — the per-landblock
-  delta-apply installer, not the old clone loop.
- `MirrorOwnerFrom` (`ShadowObjectRegistry.cs:1961,2011,2079`) —
-  repurposed for the O3 commit-time reflood.
- `OwnerMutated`/`OwnerPrefixMembershipChanged` events — general-purpose,
-  unrelated to the deleted journal.
- `RetryDeferred` (`RuntimeSetPositionState.cs:4103` et al.) — the
-  deferred-SetPosition subsystem, unrelated.
- `LandblockReplacementBuilder` `.WorkUnits/.Advance/.Completed` — the
-  live seal builder, not the deleted staging builder.
-
-## Post-Revoke audit
-
-`Revoke()` has exactly one call site (`PhysicsEngine.cs:381`, end of
-`CommitLandblockReplacement`). `MarkCommitted` (`RuntimePhysicsState.cs:
-372-380`) + `LandblockPhysicsPublisher.cs:505/:1177-1183` guards mean no
-production or test site dereferences a revoked slot. `prepared.Engine`/
-`DataCache` remain unguarded by design (ObjectDisposedException is the
-intended revoked behavior).
-
-## Stale docs/comments that now describe the DELETED design (rewrite when
-landing the collision work)
-
- `docs/architecture/acdream-architecture.md:504-566` — full section on
-  journal/write-through/rebase/root-transfer: STALE, needs rewrite to
-  the per-landblock delta commit.
- `memory/project_collision_port.md:50-88` — same content class, STALE.
- `docs/research/2026-07-31-atomic-collision-generation.md` — whole file
-  documents the deleted mechanism with no supersession note (the
-  prepared banner is in docs-drafts.md).
- `src/AcDream.Core/Physics/PhysicsDataCache.cs:126-130` XML doc —
-  describes the deleted one-leaf-per-step materialization.
- `src/AcDream.App/Streaming/LandblockPhysicsPublisher.cs:621-625`
-  comment — "zero-work root transfer" no longer true.
- Correctly archival (no action): `retail-divergence-register.md:113`
-  (~~AD-6~~ retired entry); the placement-cutover plan + C3c closeout
-  (they name the clone as the known problem being fixed).

-# P1 — origin-recenter retirement-receipt loop
-
-## Observed failure
-
-`launch-feeltest-oclone.log` contains 243 consecutive failures with this
-shape:
-
-```text
-streaming: origin-recenter preparation will resume:
-InvalidOperationException: Landblock 0xC85AFFFF already has a full
-retirement receipt.
-```
-
-The stack is `StreamingController.TryAdvanceOriginRecenterPreparation` →
-`LandblockPresentationPipeline.DetachAllForOriginRecenter` →
-`LandblockRetirementCoordinator.AdoptDetachedFull`.
-
-## Root cause
-
-An ordinary full retirement detaches every landblock-owned presentation
-resource first, then parks surviving live entities in
-`GpuWorldState._pendingByLandblock` while the exact cleanup ticket advances
-asynchronously (`GpuWorldState.DetachLandblock`, around lines 1188–1314).
-
-The origin-recenter swap incorrectly treated every pending-only live bucket
-as another landblock presentation generation (`GpuWorldState.cs`, former
-lines 1352–1353). It therefore emitted a second full cleanup receipt for the
-same already-retired generation. `LandblockRetirementCoordinator` correctly
-rejected that duplicate at lines 416–425. Because spatial detachment had
-already committed, the broad retry catch in
-`StreamingController.TryAdvanceOriginRecenterPreparation` then repeated the
-detach against the changed state every frame.
-
-The pre-fix regression test
-`OriginRecenterAdoption_PendingOnlyLiveProjectionDoesNotCreateSecondFullReceipt`
-failed because the recenter returned one receipt for the pending-only bucket.
-
-## Retail and reference boundary
-
-Retail destroys one concrete landblock owner synchronously:
-`CLandBlock::destroy_static_objects` (`0x0052FA50`) leaves and deletes the
-landblock's static objects; `CLandBlock::Destroy` (`0x0052FAA0`) releases its
-buildings and landblock data; `CLandBlock::release_all` (`0x0052FCF0`)
-releases the landblock's object and visibility ownership. A live object
-parked outside a loaded landblock is not a second `CLandBlock` and therefore
-cannot create a second landblock-destruction transaction.
-
-The extracted WorldBuilder reference follows the same ownership boundary:
-`ObjectRenderManagerBase` removes an actual `_landblocks` entry before
-`UnloadLandblockResources`, and `PortalRenderManager` only unloads a removed
-`PortalLandblock`. Neither treats an independently parked object as a new
-landblock resource owner.
-
-Acdream retains its approved asynchronous adaptation: the first exact
-receipt owns cleanup, while the live projection survives spatial recentering.
-
-## Fix
-
- `GpuWorldState.DetachAllForOriginRecenter` no longer creates retirement
-  receipts from `_pendingByLandblock` alone. Pending live identities are
-  still captured from `_projectionLocations`, cleared atomically, and
-  re-parked unchanged.
- A landblock that also owns loaded, pending-render, pending-near, tier, or
-  bounds state still receives its exact full receipt.
- A receipt-ledger invariant thrown after spatial detachment is now surfaced
-  as a committed `StreamingMutationException`; it is terminal rather than
-  falsely logged as resumable work.
- The genuine duplicate-receipt guard remains unchanged.
-
-## Deterministic evidence
-
- The new pending-only regression failed before the source fix and passes
-  afterward.
- `OriginRecenter_PendingOnlyLiveProjectionKeepsItsExistingRetirementOwner`
-  drives the production recenter/controller sequence and proves the origin
-  commits while the first cleanup ticket remains pending.
- `OriginRecenter_CommittedReceiptInvariantFailsFastInsteadOfReplayingDetach`
-  proves a genuine post-detach ledger violation surfaces once rather than
-  entering a frame-by-frame retry loop.
- The complete `OriginRecenter` focused group passes 20/20.
-
-## Gate evidence
-
- Release build: 0 errors (21 pre-existing warnings).
- Complete Release suite: 10,815 passed, 0 failed, 4 skipped.
- Connected lifecycle/reconnect gate:
-  `logs/connected-world-gate-20260802-203751/report.json` — `Passed=true`.
- Connected nine-stop soak:
-  `logs/connected-r6-soak-20260802-204309.report.json` — `Passed=true`,
-  `Failures=[]`, graceful exit, all 9 canonical checkpoints present, no wait
-  cue, no pending landblock retirement, no reveal invariant failure, and no
-  render-shadow mismatch.
- The soak artifacts contain zero occurrences of
-  `already has a full retirement receipt`; the captured failing session had
-  243.

-# User feel-test observations — O-slice tree (2026-08-02 ~20:10, uncommitted)

-   user-visible symptom despite the soak's publication convergence.
-2. MONSTERS SPAWNED MID-AIR far ahead at a newly-entered area.
-3. STATICS ("stabs") PLACED INCORRECTLY — visibly wrong static placement.
-4. User: "This is not how retail worked. I could see monsters way in

-5. DOOR APPROACH REGRESSED: using a door no longer walks the character
-   to it first. NOTE: likely a COMMITTED C3c regression, not O-slice —
-   prime suspect is PlayerModeController's conditional MoveTo bind
-   (`if (controller.MoveTo is { } moveTo)` — the flip only binds
-   approach callbacks IF the Runtime-owned MoveToManager already exists;
-   the legacy path CREATED it via factory at attach). If Runtime's
-   MakeMoveToManager runs after player-mode attach (or never for this
-   flow), MoveToComplete/approach never wires. Triage first in the C3c
-   fix slice; check whether the 175401 gate probe ever exercised a
-   door/use-approach (suspect: no coverage).
-
-SMOKING GUN (log): 243x "streaming: origin-recenter preparation will
-resume: System.InvalidOperationException: Landblock <id> already has a
-full retirement receipt." — continuous catch-retry loop during origin
-recenter. Both reviewers redirected with this; the implementer's

-The catch-and-resume wrapper is itself suspect as a pre-existing
-symptom-swallower (no-silent-catch rule).

-   trying to cast while standing still. Suspect: the conductor placement
-   path lacks the legacy spawn path's #270 settle sweep (contact from the
-   compressed first gravity frame) -> outbound contact state says
-   airborne. Routed to F4 as a lead (unified-hypothesis check); if F4's
-   stuck item is not the player, this becomes its own slice (F5) BEFORE
-   the C3c commit — casting is core gameplay and blocks the smoke test.
-2. MATERIALIZATION HAZE RE-FIRING while standing still (flip-suspect):
-   purple haze re-triggers around the character. Plausibly the visible
-   face of the soak's pendingPublications=1 stuck item if that item is
-   the local player. Routed to F4.
-3. NO SLIDE ALONG IMPASSABLE SLOPES: walking into too-steep terrain does
-   not glide laterally. Likely pre-existing open issue #269 (Campaign P
-   slope-slide residual). Verify pre-existence during the review/closeout;
-   do not fold into C3c unless evidence says the flip changed it.
-4. /ls DOES NOT WORK: unclear which command surface (chat slash command?).
-   Triage at the session; low priority.
-
-Review-focus implication: retail reviewer must verify the flip preserves
-the legacy spawn path's contact seeding (#270) semantics; adversarial
-reviewer must verify the placement publication for the local player
-actually completes and is reaped.
