Our flood does the same (3→43, headless +`FloodDepthFrom015E_VsRetail26` = max 43 vs retail 26). So retail does NOT keep the spiral +where we drop it — the flood is EXONERATED as the cause. **The vanish must be DOWNSTREAM of +the flood** (unexplored): the steps in these spiral cells are STATIC objects (GfxObj +`0x010000DE` ×6/cell), drawn via the separate viewcone cull (`ViewconeCuller.SphereVisibleInCell` +/ `DrawCellObjectLists`), NOT the cell shell — acdream may cull those step statics where +retail doesn't. OR a per-pose clip difference at the exact descending gaze (would need +retail's gaze — not yet captured — to confirm, but the matching num RANGES argue against it). +cdb watchout CONFIRMED THE HARD WAY: `qd` in a CONDITIONAL bp action does NOT fire (stuck +cdb → had to kill it → took retail down). Reliable detach = bp action falls through to BREAK +after N (no gc), then top-level `qd` (`tools/cdb/pview-spiral2.cdb`). NEXT: probe acdream's +step-static (0x010000DE) draw/viewcone in the spiral vs the cell shell. + +**⚠️ UPDATE 2026-07-07 (session 3) — fix#1 (edge-on eye-in-opening rescue) FAILED the +visual gate + REVERTED; [flood-collapse framing superseded by 3b — retail's flood collapses +the same way, so the flood is not the differentiator]. The mechanism is a GRAZING/SLIVER +FLOOD COLLAPSE in the tight SPIRAL staircase, NOT the edge-on-in-plane case.** Live [stair-clip]+[flap] capture +(`launch-177-stairclip.log`, PROBE_FLAP): the user's staircase is the `0x8A02` SPIRAL +`01C0→01C1→…→01C8→0210→…` (cells stacked z 0..6, joined by floor/ceiling portals + turning +via alternating ±Y wall portals; the recurring `0x010000DE`×6 statics are the steps). At the +vanish, root=`01C8`, vis collapses **12→3**: the DOWN floor-portal `→0210` goes OFF-SCREEN +(`clip=0`, D=3.75 — NOT edge-on) and the wall portals `→01C4/01C9` project to SLIVERS +(`clip=3`), so the flood barely spreads and 9 cells (the spiral) drop. Turning slightly +re-admits (portals swing on-screen); zoom-out gives a top-down shaft view (aligned floor +portals) → floods down → visible. **The camera is NOT collision-jammed** — `[flap-sweep]` +`pulledIn=0.00` across all 103k frames, full boom, `collNormValid=False` — so it is purely +the flood/clip, from a NATURAL chase pose. This is the #119/#181 grazing/sliver-clip class. +**The retail contradiction (hit 3×):** retail draws only the flood (`PView::DrawCells` +`cell_draw_list`) and `polyClipFinish` also rejects <3-vert slivers — so retail's flood +*should* collapse the same way, yet the user's retail shows the spiral. Something about +retail's viewpoint or flood in a spiral differs in a way NOT derivable from static analysis. +**NEXT: cdb-trace retail descending this spiral** (capture `PView::ConstructView` → +`cell_draw_list` contents + `Render::FrameCurrent->viewer.viewpoint`) to see how retail keeps +the spiral flooded — the CLAUDE.md tool for "guessing failed twice."

The handoff mis-identified the staircase. +- **The steps are cell SHELL geometry** (drawn whole/unconditionally when the cell is + admitted), so the vanish ⇒ the cell drops from the flood. +- **MECHANISM: you can flood DOWN a staircase but not UP it.** `[vis]` sets: root `01C1` + (top) ⊇ {015F,015E}; root `015F` drops `01C1`; root `015E` drops both `015F` AND `01C1`. + The up-cell dies at the **CLIP, never the side test** (root `015F`→`01C1`: CULL=0, + edge-on clip≤0 = 1508/1782). The chase-camera eye on a staircase sits at/near the cell + boundary = the floor/ceiling portal PLANE (local eye-z ≈ 6.0 = the ceiling, `D≈0`), + so the vertical portal projects EDGE-ON (collinear, <3 verts) → `ClipPortalAgainstView` + rejects it → the stacked cell above never floods in → the whole staircase above the + camera vanishes.

NEXT: user visual +gate (retail side-by-side, chase a fleeing player) → then strip the #170 probes +(`s_mvtoDiag`, `s_drainDiag`, `[npc-tick]`, `UM ↳ actions`) and close. +**Severity:** MEDIUM (visual — remote combat / aggro) +**Filed:** 2026-07-03 (user retail side-by-side during the R5-V2 visual gate) +**Component:** animation, remote entity, combat + +**Description:** A monster chasing + attacking the player (aggro) renders wrong +vs the retail client running against the SAME local ACE. User side-by-side: +retail plays proper animations, positions the monster better, plays DIFFERENT +attack animations (variety), and the attack-animation FREQUENCY is correct; +acdream shows the creature "stuck in the attack animation, gliding after me." +Because retail gets the identical ACE motion stream and renders it correctly, +the divergence is CLIENT-side (acdream's UM/animation handling), **not** ACE. + +Three distinct sub-divergences: +1. **Wrong/uniform attack animations** → **#159 is DONE (`2de5a011`) but was a + RED HERRING for this creature.** The Mite Scamp's attacks are wire + `0x62/0x63/0x64` = `AttackHigh1/Med1/Low1`, which live in the ALREADY-CORRECT + low block — they were never misnumbered, and `CombatAnimationPlanner` isn't + even wired into the runtime dispatch (the live path is `AnimationCommandRouter` + → `MotionInterpreter`/`AnimationSequencer`). #159 fixed a genuine latent bug in + the late block (Offhand*/Attack4-6/Punch*) but does not touch this symptom. + The "uniform/same animation" is therefore NOT a classification-numbering bug — + it is sub-bug 2 below (the same attack replays because `pending_motions` + completes+re-queues) and/or the sequencer not selecting per-command frames. +2. **Over-frequency / stuck attack** — motion trace: ACE streams attack UMs + (`mt=0x00 cmd=0x62/0x63/0x64 spd=0.97`) on top of the `mt=0x06` chase; + acdream's `pending_motions` completes+re-queues in a tight MOTIONDONE loop + (`pending=True` spam) → over-plays. R3/R4 pending_motions/MotionDone area. +3. **Glide** — the creature's position moves (mt-6 moveto + UP dead-reckon) but + no locomotion legs play (attacks override) → smooth slide. AP-80 / #160 + dead-reckon-vs-animation family. + +**Evidence:** `ACDREAM_DUMP_MOTION` trace for guid 0x80000244 — `mt-0 stance 0x3C` +→ `mt-6 chase spd 2.03` → stream of `mt-0` attacks `0x62/63/64 spd 0.97`; +MOTIONDONE loop between `0x8000003C` (stance) and the dispatched motion. + +**NOT V2/R5:** the voyeur target-tracking correctly makes the creature chase +(the `mt-6` is proof); this is the animation/position layer. + +**Where:** `MotionInterpreter`/`AnimationSequencer` attack-motion dispatch + +`pending_motions`; `CombatAnimationPlanner` (#159); `ServerControlledLocomotion` ++ remote dead-reckoning (glide). + +**Acceptance:** side-by-side with retail — a chasing+attacking Mite Scamp shows +correct attack-animation variety, correct frequency, and steps/runs (no glide). + +**Investigation 2026-07-04 (code-grounded mechanism, HYPOTHESIS — pending live +confirmation):** traced the live remote path end-to-end. The chase (`mt-6` +MoveToObject) is owned by the entity's verbatim `MoveToManager` +(`GameWindow.RouteServerMoveTo`, ~4899) — this is what moves the legs. The +attacks arrive as SEPARATE `mt-0` InterpretedMotionState UMs and flow through +`MotionInterpreter.MoveToInterpretedState` (~4985).

So each `mt-0` + attack UM **cancels the active chase MoveTo.** +2. `MoveToInterpretedState` → `ApplyInterpretedMovement(cancelMoveTo:true)` + installs the UM's `ForwardCommand`, which for an attack-only UM defaults to + **Ready/idle** (`ims.ForwardCommand = fullMotion`, null/0 → Ready, ~4933) → + the run cycle is replaced by idle while the body keeps its dead-reckon + translation → **glide**; the creature is repeatedly knocked idle+attack + rather than running (over-play / "stuck"). +The `ServerActionStamp` 15-bit gate (`MoveToInterpretedState` ~2845) IS faithfully +ported, so identical-stamp replays are already suppressed — the "uniform anim" is +NOT a stamp bug. This coexistence of MoveTo (chase) + interpreted-state (attack) +is **explicitly R5/MovementManager scope** (GameWindow ~4816 "LoseControlToServer +autonomy handoff is R5/MovementManager scope"). So #170 sub-bugs 2/3 are +**downstream of the incomplete MovementManager port (R5-V4), not #159 and not a +localized bug.** NEXT: (a) confirm with a labelled `ACDREAM_DUMP_MOTION=1` capture +of the Mite Scamp (exact mt-6/mt-0 interleave + what ForwardCommand + stamps the +attack UMs carry), (b) retail side-by-side — does retail keep the legs running +during attacks and re-establish the chase between swings? — then port the retail +MovementManager coexistence (R5-V4).

A character saved FAR from the startup center (0xA9B4 Holtburg) +triggers a login-spawn `RecenterTo` against that stale, half-loaded window; +`RecenterTo` trusts `_tierResidence`, so the old/new window overlap is never +re-enqueued — a permanent HOLE of resident-but-never-loaded landblocks (zero +`BUILD-NULL`; they're simply skipped). The player spawns in the hole → its +landblock never loads → terrain/NPCs/player never draw ("world loads behind me, +character invisible"). Probe: spawn at 0xADAF, column 0xAD loaded Y=0xA3-0xAA + +0xB0-0xC0 but MISSING Y=0xAB-0xAF; player at 0xADAF (Y=0xAF) dead in the gap. +**Fix:** a far login-spawn moves the render origin like an outdoor teleport +(which already calls `StreamingController.ForceReloadWindow` — drop stale window ++ re-bootstrap fresh at the new origin); the login-spawn recenter now flags that +rebuild (network thread → set flag → render thread consumes it before the Tick). +Verified: 0xADAF now loads (216 entities), full world draws, player recovers. +No-op for a normal Holtburg login. NOT R5 (pre-existing streaming bug). + +## #168 — Invisible player / character disappears (pending-bucket trap) + +**Status:** DONE (`315af02f`, 2026-07-03) — root confirmed live via +`ACDREAM_PROBE_ENT`. **Cause:** a persistent server-spawned entity that spawns +into a not-yet-loaded landblock is parked in `GpuWorldState._pendingByLandblock`. +`RelocateEntity` (per-frame, keeps the player homed to its current landblock so +it draws) scanned ONLY `_loaded`, so it silently no-op'd on a pending entity — +and the player fell through all recovery paths (the AddLandblock drain already +ran empty; the server-object re-hydrate excludes the player; RelocateEntity +couldn't reach pending) → stranded invisible. This is the mechanism behind BOTH +"cold-spawn invisible" AND "character disappears running out of Holtburg far +enough" (both = player parked in pending, never recovered). **Fix:** +`RelocateEntity` now removes the entity from whichever bucket it occupies +(`_loaded` OR `_pendingByLandblock`) then re-appends to its current landblock — +promoting a stranded pending entity to drawn as soon as its landblock loads. +Test: `GpuWorldStateTests.RelocateEntity_StrandedInPending_MovesToLoadedTarget` +(red→green). Composes with #169.

Retail arms the leash +ONLY from `SmartBox::HandleReceivedPosition` (0x00453fd0) — on every inbound +server position packet, anchoring the mover to self (remotes) or the received +position (player) — with a start/max distance band from +`CPhysicsObj::GetStartConstraintDistance` (0x0050ebc0) and +`GetMaxConstraintDistance` (0x0050ec10). acdream's position reconciliation is +not `SmartBox`, so nothing calls `PositionManager.ConstrainTo`, and +`IsFullyConstrained` stays false (= register **TS-35**'s current stub +behavior — jump never blocked by the leash). + +**Blockers:** (1) the two distance constants are **x87 float returns BN +elided** — `GetStart/MaxConstraintDistance` decompile to a bare +`this->m_position;` expression with the actual returned value lost to the +FPU-return-elision artifact. Recovering them needs a live cdb read of `st0` +after the call (retail debugger toolchain) or a Ghidra re-decompile with a +corrected float-return signature. (2) The arming site (`SmartBox`'s inbound +position-reconciliation branches A/B/C) has no acdream equivalent yet — wiring +it means teaching acdream's position path to re-anchor the leash on every +server position update, then feeding the `adjust_offset` taper into the body +integration (same chokepoint as the sticky wiring, R5-V3). + +**Where:** `src/AcDream.Core/Physics/Motion/ConstraintManager.cs` (class, +unarmed); the read gate is `PhysicsBody.IsFullyConstrained` (TS-35) via +`jump_is_allowed`.

Fix: +`RemoteWeenie` (retail's per-object ACCWeenieObject stand-in; InqRunRate +fails → my_run_rate fallback) on every RemoteMotion interp. +**Symptom:** observing a retail player's server MoveToChain from acdream: +close-range movetos WALK correctly; at run distance the RUN cycle plays but +the body moves visibly slower than the legs (treadmilling). The legs' pace +comes from the manager's dispatch (`_DoMotion` → `apply_run_to_command` × +`MyRunRate` = the wire's mt-6 `MoveToRunRate`, observed 4.50 for a +high-skill char); the body's position is queue-chased from ACE's actual +UpdatePosition stream — evidently slower than that rate. Speed-source +disagreement: either ACE's chain moves slower than the advertised runRate, +or our dispatched cycle speed over-scales (compare: local player run pace +was correct). **Evidence to gather:** UP cadence Δpos/Δt for the mover vs +`RunAnimSpeed × dispatched speed`; check what speed ACE's MoveToChain +actually steps at (Player_Move.cs / Creature GetRunRate usage). +**Where:** GameWindow `TickRemoteMoveTo` + the L.3 M2 queue chase vs +`MotionTableDispatchSink` dispatch speed.

Ground truth was taken by reflecting over the same DatReaderWriter 2.1.7 assembly the runtime binds (409 enum values). Blocks 1-2 (stances + single melee, 0x3C-0x12A) were already correct; the late block (Offhand*/Attack4-6/Punch*, 0x173-0x19A) was all +3 shifted; `Reload` was the dead 2013 value `0x100000D4` (absent from DRW) → now the real `0x40000016` SubState. New parity test `PlanFromWireCommand_LateCombatBlock_UsesAceDrwNumbering` pins 14 ACE wire values through the full wire→resolve→classify pipeline. **Caveat (relevant to #170):** `CombatAnimationPlanner` is not yet wired into the runtime — the live dispatch is `AnimationCommandRouter` → `MotionInterpreter`/`AnimationSequencer` — so this is a *latent* correctness fix. It does NOT by itself change the #170 Mite Scamp symptom, whose attacks `0x62/0x63/0x64` live in the already-correct low block. #170 sub-bugs 2 (MOTIONDONE loop) + 3 (glide) remain. +**Severity:** MEDIUM (late-combat animation classification wrong against ACE) +**Filed:** 2026-06-30 +**Component:** animation, combat + +**Description:** `CombatAnimationPlanner.CombatAnimationMotionCommands` hardcodes the late-combat command constants (the `Offhand*` / `Attack4-6` / `Punch*` block) using **2013-decomp numbering** instead of the ACE/DatReaderWriter numbering that ACE actually broadcasts and that the local DAT MotionTables use. Per the +3-ish low-word shift documented in the ACE-vs-2013 gap research, e.g. `OffhandSlashHigh` should be `0x10000173` not `0x10000170`; `AttackLow6` should be `0x1000018E` not `0x1000018B`. Against a live ACE server these specific commands will be silently misclassified (resolver returns the correct ACE value, but the planner's set contains the 2013 value, so no match). + +**Root cause / status:** Pre-existing — surfaced by the L.1b command-catalog slice (commit pending). The old blind `0x016E–0x0197` override in `MotionCommandResolver` masked the matching test (`CombatAnimationPlannerTests.MotionCommandResolver_UsesNamedRetailLateCombatCommands`) by force-mapping the same wire range to 2013-class values, so the test agreed with the planner's wrong numbering. Deleting the override (correct) exposed the mismatch. NOT a regression: for the real ACE wire value (`0x0173`), the resolver returns `0x10000173` both before and after the override deletion, so runtime behavior is unchanged — the planner was already misclassifying it. The fix is to renumber the `CombatAnimationMotionCommands` block to the ACE/DRW values (cross-check each constant against `DatReaderWriter.Enums.MotionCommand`). + +**Files:** `src/AcDream.Core/Combat/CombatAnimationPlanner.cs:268-307` (the hardcoded `CombatAnimationMotionCommands` block). + +**Research:** `docs/research/2026-06-26-ace-vs-2013-motion-command-gap.md`. + +**Acceptance:** Each late-combat constant in `CombatAnimationMotionCommands` matches its `DatReaderWriter.Enums.MotionCommand` value; a parity test asserts the ACE wire values (`0x0173 → OffhandSlashHigh`, etc.) classify correctly through `ClassifyMotionCommand`. + +--- + +## #158 — Character window — deferred polish + +**Status:** OPEN +**Severity:** LOW +**Filed:** 2026-07-03 +**Component:** ui / net + +**Description:** UseDone (0x01C7) refusals now surface in chat, but the text comes from `WeenieErrorText.For` — a hardcoded subset map (0x001D/0x04EB/0x04FC/0x04FE) with a generic fallback.

Retail overlays a high-frequency **landscape detail texture** on the base ground; that overlay is what keeps retail's ground crisp up close. Filtering is NOT the problem (the ground array already has mipmaps + `LinearMipmapLinear` + 16× anisotropy, `TerrainAtlas.cs:187-193`); resolution is NOT the problem (terrain is 512² in both Portal and HighRes). + +**Verified retail mechanism (decomp `docs/research/named-retail/acclient_2013_pseudo_c.txt`):** +- Dat fields on `DatReaderWriter.Types.TerrainTex` (confirmed via reflection on Chorizite.DatReaderWriter 2.1.7): `DetailTextureId` (`QualifiedDataId`, `.DataId`) + `DetailTexTiling` (`uint`). acdream currently reads neither (only `TextureId`). +- `ACRender::landPolyDraw` 0x006b6525 (lines 702299-702300): **detail UV = `curr_detail_tiling × baseUV`** (the detail texture tiles `detail_tiling×` relative to the base). +- `landPolyDraw` 0x006b6450-0x006b649c (lines 702263-702287): **distance fade** — detail alpha is FULL at camera depth `< 10`, lerps to 0 by depth `50`, gone beyond.

It **compiled, linked, ran with no GL error** — but the ground rendered **black/dark up close**: the detail array sampled near-zero, so MODULATE2X collapsed `rgb` to 0. **The bindless handles were verified NOT swapped** (renderer correctly binds `(terrain, alpha, detail)`). The bug is in the detail-texture **DATA**: the no-detail gray fill (`NoDetailGray=128`) didn't land as neutral, OR `DetailTextureId` decodes dark/black, OR AC's detail textures are not 0.5-centered (so MODULATE2X darkens). Reverted via `git checkout` — terrain back to the working (blurry) state. + +**NEXT (debugging steps for the fresh pass):** +1. **Dump the detail array content** — are the layers ~0.5 gray or ~0 black?

If the textures decode dark, AC detail textures may not be gray-centered → use plain MODULATE or re-center, not MODULATE2X. Confirm the actual blend visually. +3. Confirm `DetailTextureId` → `SurfaceTexture` → `RenderSurface` resolves (do the detail textures even exist for these terrain types? many may be 0 → must fall to the gray no-op). +4. Use retail's **single landscape scalar** (`TerrainDesc[0].DetailTexTiling`, default 2.0), not per-type (faithfulness note above). +5. Gate behind an `EnvironmentDetailTextures` equivalent. +6. **Secondary (separate, unconfirmed):** is the base `TILE=1.0` (once per cell) correct vs retail?

Server-spawned DOORS still block (they register their own collision via CreateObject), and terrain stays solid — so the symptom is specifically dat-static building-wall collision after a portal-in. + +**Root cause (capture-narrowed, one probe from confirmed):** The building collision channel (`TransitionTypes.FindBuildingCollisions` → `PhysicsDataCache.GetBuilding(cellId)` → BSP test vs `BuildingPhysics.WorldTransform`) IS reached after a portal-in — the `[bldg-channel]` probe fires at Holtburg post-portal (`cell=0xA9B40022 model=0x01000C17`) — but every test returns `result=OK` (no penetration) as the foot-sphere walks into the wall (`arwic-to-holtburg-bldg-capture.log`). The building's `WorldTransform` is computed from `_liveCenter` AT CACHE TIME (`GameWindow.cs` ~6969: `building.Frame.Origin + origin`, `origin = (lb − _liveCenter)·192`) and `CacheBuilding` is IDEMPOTENT (`PhysicsDataCache.cs:444` `if (_buildings.ContainsKey) return;` — never re-cached, never cleared on unload). A teleport recenters `_liveCenter`, so the cached shell BSP can sit at a stale world offset → the sphere never penetrates → no block. Same streaming-relative-frame family as #145/#147. + +**Next step (one probe before fixing):** add `building.WorldTransform.Translation` to the `[bldg-channel]` line; if it's offset from the visual building / player position after a portal-in, the stale-transform root is confirmed.

Same root as the Z free-fall (`#135`/`#138` placed-but-unstreamed gap). **DO NOT guess-patch** (original #145 burned 5 attempts) — needs a capture + an anchor/guard diagnostic at the crossing FIRST.

The first teleport works; a subsequent portal use (run out, or re-enter) does not. Goal: run in, run out, repeatedly. + +**Root cause (CONFIRMED — code trace + live cdb-style [phys-lb] probe):** the teleport OUT of a dungeon mis-rooted the player into the SOURCE dungeon's coordinate frame, desyncing all movement from ACE. acdream uses a streaming-RELATIVE coordinate frame (positions relative to `_liveCenterX/Y`) and recenters on teleport, but **resident physics landblocks keep their load-time world-offset**. After recentering onto the outdoor destination, the collapsed source dungeon (loaded at offset (0,0) when it was the center) and the destination (also the new center → offset (0,0)) **overlap**, and the Z-agnostic outdoor cell-snap (`AdjustPosition`, iterating `_physicsEngine._landblocks`) returns the dungeon — for the arrival placement AND every per-frame resolve — so the player was rooted at a dungeon cell (`0x00070019`) at Holtburg's position. acdream then sent dungeon-frame positions; ACE (which knows the player is at Holtburg) rejected every one (`WARN: failed transition … to 0x0007…`), so the player couldn't move, never reached a portal, and ACE never re-broadcast the Holtburg objects. Teleport IN works because its placement is cell-keyed (indoor `FindVisibleChildCell` validates the specific claimed cell) and it pre-collapses; the OUTDOOR resolve is the grid-snap, which the overlap fools. + +**Fix (2026-06-20) — server-authoritative teleport placement (user-approved approach):** +1. **Drop the stale source center landblock from physics at the teleport recenter** (`GameWindow.OnLivePositionUpdated`, `differentLandblock` branch → `_physicsEngine.RemoveLandblock(EncodeLandblockId(oldCenter))`). Only the offset-(0,0) center collides with the destination-local position, so removing it alone clears the overlap; the arrival + per-frame resolve then fall through to the server position (`PhysicsEngine.Resolve` NO-LANDBLOCK verbatim, `:605`) until the destination streams in. +2. **Place outdoor teleports immediately** (`TeleportArrivalRules.Decide` — outdoor → Ready). Holding is futile: streaming does NOT progress while the player is held in PortalSpace (the destination only loads once placement flips to InWorld). Indoor unchanged (`IsSpawnCellReady` hold). Gate suppression during the hold kept (`DungeonStreamingGate`). +3. **Clear a dangling `CellGraph.CurrCell` when its landblock is removed** (`PhysicsEngine.RemoveLandblock`). Without this, dropping the dungeon left CurrCell pointing at the orphaned dungeon cell; the dungeon-streaming gate (keyed on CurrCell) kept streaming collapsed onto the gone landblock, so the destination never streamed → only skybox.

The first fix (`45a5cc5`) folded `ZLevel` into `ZOrder` and put the backdrop behind the **ZLevel-0 top-level** panels, which made the **paperdoll** (its base root is ZLevel 0) render — so it *looked* done. But the **mounted backpack/3D-items panels** inherited their sub-window root's **ZLevel 1000** (via `ElementReader.Merge`'s zero-wins-base rule), so the `ReadOrder − ZLevel·10000` fold sank them to ZOrder ≈ −10,000,000 — *behind* the backdrop (ZLevel 100 → ≈ −1,000,000). The Alphablend backdrop then **washed out** the backpack/3D-items captions + burden meter + item cells (only the bright paperdoll survived the wash). Surfaced once B-Controller populated those panels. Continuation fix `417b137`: the sub-window mount keeps each slot's **own** frame ZLevel (not the base root's 1000), so panels sit in front of the backdrop. Confirmed live (Burden 17% + vertical bar + "Contents of Backpack" + full item grid all render on the dark backdrop).

Fix: factory `ZOrder` should honor `ZLevel` (higher `ZLevel` = further back) with `ReadOrder` as the tiebreaker — e.g. `ZOrder = ReadOrder − ZLevel·K`. `ElementInfo` has no `ZLevel` field yet (add it + read in `ElementReader.ToInfo` + carry in `Merge`). **Regression risk:** touches z-order for every window — must verify chat (`0x21000006`) + toolbar (`0x21000016`) `ZLevel`s (vitals are all 0) and visually regression-test. + +**Files:** `src/AcDream.App/UI/Layout/DatWidgetFactory.cs` (`e.ZOrder = (int)info.ReadOrder`, ~:81); `src/AcDream.App/UI/Layout/ElementReader.cs` (`ElementInfo` — add `ZLevel`; `ToInfo`; `Merge`); `src/AcDream.App/UI/Layout/LayoutImporter.cs`. + +**Research:** `docs/superpowers/specs/2026-06-20-d2b-inventory-grid-mount-design.md` (B-Grid); dat dump of `0x21000023` (panels ReadOrder 1-3 / ZLevel 0; backdrop `0x100001D0` ReadOrder 4 / ZLevel 100). + +**Acceptance:** F12 shows the nested paperdoll/backpack/3D-items panels over the backdrop (backpack burden meter + slot borders visible); vitals/chat/toolbar unchanged; full suite green. + +--- + +## #142 — Windowed-building interiors read "like outdoors" (indoor lighting regime is per-frame, not per-stage) + +**Status:** DONE (2026-06-20) — `ef5049f` (per-instance sun gate) + `0d8b827`.

This is the toolkit's general click semantics — every non-draggable widget (buttons included) fires Click after sub-gesture mouse movement; only an *armed* drag suppresses the click. Today it is a **no-op**: the toolbar's `Clicked` handler guards `if (Cell.ItemId != 0)`, so an empty-slot click uses nothing. + +**Root cause / status:** Surfaced in the B.1 spine code review (Task 3). Whether retail fires nothing vs. a no-op click on an empty cell after a >3 px move is **unverified** — deliberately NOT "fixed" with a speculative `_dragCancelled` guard, because that would make empty item-slots behave differently from every other widget and would be guessing at retail behavior (CLAUDE.md forbids both). Becomes relevant only if a future panel (e.g. the inventory grid in Stream C) wires an empty-cell click handler that does NOT guard on occupancy.

Retail's per-object torch binder `minimize_object_lighting` (0x0054d480) runs ONLY `if (Render::useSunlight == 0)` (`DrawMeshInternal` 0x0059f398), and the OUTDOOR landscape stage runs `useSunlightSet(1)` (`PView::DrawCells` 0x005a485a before `LScape::draw`). So retail lights outdoor objects (building exterior shells, scenery, outdoor creatures) with the **sun + ambient ONLY — never wall torches**. acdream was torch-lighting them. Fix: `WbDrawDispatcher.ComputeEntityLightSet` now gates torch selection on the object being indoor (`ParentCellId` is an EnvCell) via `IndoorObjectReceivesTorches`; outdoor objects get the sun only. acdream reads the dat falloffs faithfully (the orange torch is genuinely `Falloff 6`; the "reach too long" theory was a red herring). Register **AP-43**; the indoor-vs-outdoor *sun* half uses a per-frame player-inside global (residual logged in AP-43). Full handoff: `docs/research/2026-06-19-lighting-a7-fixD-round2-torch-reach-CHECKPOINT.md` (RESOLVED banner). Indoor-lighting follow-ups the user raised at the gate (windowed-building interior regime; portal swirl as a dynamic light) are SEPARATE M1.5 work, not part of this issue. + +**Description (user):** Outdoor buildings (e.g. the Holtburg meeting hall) read much brighter near torches in acdream than in retail — the walls blow out warm where retail stays dim. The general ambient/sun is correct after Fix C (`57c1135`); this is specifically the per-object point-light *contribution*. + +**Root cause / status:** GROUNDED but BLOCKED on one capture. Retail's object point-light path (`config_hardware_light` 0x0059ad30): `Diffuse=color×intensity`, `Attenuation=(0,1,0)`⇒1/d, `Range=falloff×rangeAdjust` (`rangeAdjust=1.5`⇒9 m), `material.diffuse=(1,1,1)`. CONTRADICTION: by that math a torch 3 m away = color×33 ⇒ retail walls should blow to WHITE — but they're DIM. Material/range/intensity all captured + ruled out. So the scaling is in the building's RENDER PATH (unknown). Leading hypothesis: static buildings DON'T use D3D hardware lighting — they use the `SetStaticLightingVertexColors` BAKE (`calc_point_light`, like cells), and the captured `intensity=100` light was a different object (player/portal). **DO NOT port the D3D-FF model — the math says it would make objects brighter, not dimmer.** + +**Files:** `src/AcDream.App/Rendering/Shaders/mesh_modern.vert` (`pointContribution`/`accumulateLights`); `src/AcDream.Core/Lighting/LightManager.cs` (`SelectForObject`); `LightBake.cs` (verbatim calc_point_light, unwired). + +**Research:** `docs/research/2026-06-18-lighting-a7-fixABC-shipped-fixD-handoff.md` (full grounding + cdb cheat-sheet + the next capture); `claude-memory/reference_retail_ambient_values.md`. + +**Acceptance:** Determine the building's actual render path (bake vs D3D-FF; is `SetStaticLightingVertexColors` 0x0059cfe0 called for it / is `D3DRS_LIGHTING` on), then make the object torch contribution match retail — user side-by-side sign-off (meeting hall stays dim near torches). + +--- + +## #139 — D.2b retail UI polish: chat text colors + buttons + +**Status:** OPEN +**Severity:** LOW (cosmetic fit-and-finish — the widget generalization works and matches the prior hand-made build; this is polish vs a side-by-side retail client) +**Filed:** 2026-06-16 +**Component:** ui — D.2b retail UI (chat window + buttons) + +**Description (user):** After the widget-generalization pass landed (2026-06-16), two areas want a polish pass against retail: +1. **Chat text colors** — the per-`ChatKind` transcript text colors need tuning to match retail more precisely.

See the 2026-06-24 update at the bottom of this entry. +**Severity:** MEDIUM (breaks the dungeon→outdoor transition; collision + visuals wrong after exit) +**Filed:** 2026-06-14 +**Component:** streaming — dungeon collapse↔expand (the #133/#135 collapse) + teleport-arrival + +**Description (user):** taking a portal OUT of a dungeon to the outdoor world often loads +the world incompletely — **fewer objects than expected (e.g. missing trees/scenery)**, and +**collision doesn't work properly**. There's also a **position desync**: "it's like I'm not +moving while my character is moving" (the avatar animates/advances but the player's +actual position / camera doesn't track, or vice-versa). + +**Root cause / status (hypothesis — needs investigation):** very likely a gap in the +dungeon-streaming **collapse→expand** introduced for #133/#135. Inside a dungeon, streaming +is COLLAPSED to the single dungeon landblock (radius-0). On teleport OUT, +`StreamingController.ExitDungeonExpand` must rebuild the full 25×25 outdoor window at the new +center. Suspects: (a) the expand doesn't fully re-enqueue / re-hydrate the outdoor landblocks +(→ missing trees/scenery + no collision because shadow-object registration never ran for the +un-hydrated blocks); (b) the teleport-arrival recenter (`OnLivePositionUpdated`) + +`PreCollapseToDungeon`/observer interaction leaves the streaming observer pinned wrong after +exit; (c) the position desync = the player controller / streaming observer disagree on the +post-exit world position (the avatar moves in one frame, the streaming/camera in another). +Pairs with #135 (`712f17f`/`2c92375`) — same collapse machinery; the EXIT path is the gap. + +**UPDATE 2026-06-20 — the position-desync HALF is FIXED via #145; the remaining half is narrowed + RE-SCOPED to entity render/lifecycle:** #145 fixed the cell-rooting (the player was rooted into the source dungeon's frame on teleport-out → ACE rejected all movement → "avatar moves but position doesn't track"). With that fixed (server-authoritative placement + drop-stale-center + CurrCell clear), the outdoor TERRAIN now streams + renders and movement is accepted. What REMAINS, observed in the #145 verification run: +- **(A) Server-spawned objects don't render after teleport-back.** NOT a re-broadcast gap — the `ACDREAM_DUMP_LIVE_SPAWNS` trace shows ACE DOES re-send `CreateObject` for all Holtburg weenies on return (Doors, NPCs "Agent of the Arcanum"/"Wedding Planner", "Holtburg Meeting Hall Portal", chests, …) and acdream receives + processes them (`OnLiveEntitySpawnedLocked` → `AppendLiveEntity`). They just don't appear. So the bug is downstream: entity render/storage during the teleport streaming churn — candidates: the re-added live entities are dropped by a subsequent `GpuWorldState.AddLandblock` record-replace for the same landblock, OR the per-instance render data (`WbEntitySpawnAdapter.OnCreate`) isn't built/registered, OR a render-root/visibility gate while `CurrCell` re-acquires. +- **(B) Own avatar stops rendering after a couple of round-trips.** The player entity (persistent, rescued+re-injected via `GpuWorldState.DrainRescued`→`AppendLiveEntity` at `GameWindow` ~:7421) is lost/duplicated across repeated rescue/re-inject cycles. Cumulative (first trip OK, later trips vanish). + +Both are the **entity-lifecycle/render path across a teleport**, NOT the streaming collapse/expand (which now works — terrain streams). Start here: instrument `GpuWorldState` (AppendLiveEntity / AddLandblock / RemoveLandblock / DrainRescued) to trace one guid (a Door + the player 0x5000000B) across an in→out cycle and find where it leaves the rendered set. + +**Files:** `src/AcDream.App/Streaming/GpuWorldState.cs` (`AddLandblock` pending-merge vs record-replace, `AppendLiveEntity`, `RemoveLandblock`/rescue, `DrainRescued`, `RelocateEntity`), `src/AcDream.App/Rendering/GameWindow.cs` (`OnLiveEntitySpawnedLocked` ~:2696, rescued re-inject ~:7421), the per-instance render adapter (`WbEntitySpawnAdapter`). The streaming collapse/expand (`StreamingController`) is no longer the suspect. + +**UPDATE 2026-06-21 — root re-scoped again: it's RE-DELIVERY, not render-cull or cache.** A deep dive (probes: `[ent]` append/remove + `[ent-flat]` rendered-set count + `[dyn]` DrawDynamicsLast cull) eliminated the 2026-06-20 hypotheses: +- **NOT the Tier-1 cache.** Re-created live entities get a fresh monotonic `Id = _liveEntityIdCounter++` (`GameWindow` ~:3251), so `EntityClassificationCache` (keyed on `Id`) is ALWAYS a miss for them — never the cause. *(Side-finding, separate minor bug: the cache has a demote-vs-unload invalidation asymmetry — `RemoveEntitiesFromLandblock` fires `_onLandblockUnloaded` (`:~495`) but `RemoveLandblock` does NOT, violating the documented "demote OR unload" intent. NOT the #138 cause; fix-with-verification later.)* +- **Render path is FINE when entities are present.** At login `[dyn] rootOutdoor=True dyn=54 drawn=33` — the dynamics partition (`InteriorEntityPartition` :55, every `ServerGuid!=0` with `MeshRefs>0` → dynamic) + `DrawDynamicsLast` draw them. +- **The ACTUAL cause: re-delivery is unreliable / absent.** `notan/+Je` walk-around run: after teleport-out, `live:spawn` doors = **0**, `[ent] +` door appends = **0**, `[ent-flat] server=1` (only the player), `[dyn] dyn=1` — the server delivered **ZERO** Holtburg objects on return; they never reach acdream. (An earlier `testaccount2` run got ~15 re-sent, but the user confirmed they stayed missing then too — so re-delivery is partial AND unreliable across accounts/sessions.) "Other clients see +Je" → the server has correct player state; acdream's LOCAL world is simply missing the objects. The 2026-06-20 "NOT a re-broadcast gap" claim above was WRONG — it IS (intermittently) a re-broadcast gap. +- **Mechanism:** acdream UNLOADS the landblock's server-spawned objects on teleport-IN (the dungeon collapse unloads neighbours, including Holtburg), and on the way back NOTHING restores them; ACE does not reliably re-broadcast them (known-set/awareness desync, likely worsened by the rapid relaunch churn). + +**FIX SHIPPED 2026-06-21 — client-side re-hydrate from the retained spawn table (re-projection, not ACE re-send):** + +**⚠️ Handoff correction:** the 2026-06-21 handoff said to re-hydrate from `ClientObjectTable` ("keeps ALL objects with their positions"). That is WRONG — `ClientObject` (`src/AcDream.Core/Items/ClientObject.cs`) is the INVENTORY data model (container/slot/equip/icon/value/stack); it carries **no world position, no cell id, no Setup/PhysicsDesc/mesh**. It cannot build a render entity. The real retained world-object table is **`GameWindow._lastSpawnByGuid`** (`Dictionary`) — the parsed `CreateObject` records, carrying Position + Setup + MotionTable + AnimPartChanges + palette. It is pruned ONLY by a server `DeleteObject` or a spawn de-dup, so it **survives the dungeon collapse** (verified: the collapse path `StreamingController.Tick → GpuWorldState.RemoveLandblock` never calls `RemoveLiveEntityByServerGuid`, the only thing that touches `_lastSpawnByGuid`). + +**Cross-reference confirmation (this is retail-faithful, not a workaround):** ACE (`references/ACE/Source/ACE.Server/Physics/Common/ObjectMaint.cs`) **never clears a player's `KnownObjects` set on a normal teleport** (`teleport_visibility_fix` is off by default + flagged non-retail), so it will NOT re-send objects it thinks we still have — it relies on the client retaining its table and doing its own 25 s/384 m visibility cull. holtburger (`references/holtburger/.../handlers/player.rs`) **keeps its entire object table across a teleport** (only suspends physics bodies) and re-projects its displayed world from that table; stale far objects self-evict after a 25 s timeout. So "client keeps the object table and re-renders from it" IS retail behavior. acdream's render entities are the projection; the collapse drops the projection for FPS (AP-36), and re-hydrate rebuilds it on reload. + +**Implementation (A — server objects):** new `StreamingController` `onLandblockLoaded` callback fires after `AddLandblock` (Loaded path = dungeon-exit expand) and `AddEntitiesToExistingLandblock` (Promoted = Far→Near). `GameWindow.RehydrateServerEntitiesForLandblock` builds the set of server guids already present in `GpuWorldState`, snapshots `_lastSpawnByGuid`, and — via the pure `LandblockEntityRehydrator.SelectGuidsToRehydrate` (selects spawns in the loaded landblock that have a world mesh, are not the player, and are NOT already present) — replays `OnLiveEntitySpawnedLocked` for each missing guid under the dat lock. The replay's own `RemoveLiveEntityByServerGuid` de-dup scrubs the state the collapse orphaned (the entity lingers in `_entitiesByServerGuid` after `RemoveLandblock` even though its render entity is gone — so the present-gate keys on `GpuWorldState`, not that map). Idempotent + no double-build on initial login (entities already present → skipped). Commit: `LandblockEntityRehydrator.cs` + `StreamingController.cs` + `GameWindow.cs`; tests `LandblockEntityRehydratorTests` (7). Register row **AP-48** (no 25 s cull → a re-hydrate may restore an object the server silently dropped — port holtburger's cull to close). + +**Implementation (B — player vanish, candidate):** `GpuWorldState.RemoveLandblock` rescued persistent entities only from `_loaded`, silently dropping a persistent entity sitting in the **pending bucket** (the player is re-injected via `AppendLiveEntity` every frame; right after a teleport its landblock hasn't streamed yet → pending; if that landblock is then unloaded mid-churn the player was dropped → "vanishes after a couple round-trips"). Fix: rescue persistent pending entries too. Tests `RemoveLandblock_RescuesPersistentEntity_FromPendingBucket` (+ negative). This is a provable correctness fix for the "persistent ⇒ survives unload" invariant; it is the leading candidate for symptom B but needs user re-verification to confirm it is the complete cause. + +**UPDATE 2026-06-24 — symptom B (avatar vanish) ACTUAL root found + FIXED (`afd5f2a`, user-confirmed + trace-verified):** the pending-bucket rescue above was necessary but NOT the whole cause. The real culprit: the per-frame avatar-sync (`GameWindow` ~:8018) calls `GpuWorldState.RelocateEntity` using the player controller's cell, which stays the **FROZEN SOURCE cell** until `PlaceTeleportArrival` materializes the destination. Mid-transit it dragged the avatar — which the teleport's `DrainRescued` re-inject had correctly placed at the destination center — back into the now-UNLOADED source landblock's pending bucket, where nothing recovers it (`RelocateEntity` only scans `_loaded`). Fix: skip the per-frame relocate while `_playerController.State == PortalSpace`. Verified by a new env-gated avatar-lifecycle probe (`ACDREAM_PROBE_ENT` / `EntityVanishProbe`): pre-fix `[ent] APPEND lb=0x0007FFFF(source) -> PENDING -> DRAWSET ABSENT` never recovered; post-fix every teleport goes `RESCUE -> ABSENT -> APPEND(destination) -> PRESENT` and stays drawn. **The remaining #138 collision residual split into #152 (Holtburg/building portal-in walls, DONE `49d743f`) + #151 (Arwic far-town frame, FIXED `9743537`).** (#146/#147 in this file are unrelated D.2b inventory-polish issues.) + +**Acceptance:** portal out of the 0x0007 dungeon → full outdoor world streams (trees/scenery present), **server objects (doors/NPCs/portals) render**, **own avatar renders across repeated round-trips**, collision works, position tracks (no avatar-vs-camera desync). + +**2026-07-10 gate — PASSED, #138 CLOSED:** the user confirmed the full dungeon round-trip end-to-end — ENTER + NAVIGATE (dungeon streams, renders, collides, navigable, doors work) AND the EXIT (portal OUT to the outdoor world, world streams, collision holds, position tracks).

The +PortalSide polys to 0x011E were a red herring: cell 0x8A02016E has IDENTITY +rotation, the polys are ±Y planes perpendicular to the run (directionally +culled), retail's physics-BSP leaves reference them too, and the dat's +keep-PortalSide/strip-ExactMatch asymmetry reads as intentional (solid +window/grate-class portals) — NO portal-poly filter needed, no cdb session +needed for this repro. Dat-backed replay +(`Issue137CorridorSeamReplayTests`) reproduces the live frame exactly and +runs the corridor clean. The issue's DOOR half remains open. + +**CHARACTERIZED 2026-07-05 (Facility Hub corridor repro, probe + dat evidence) +— two stacked mechanisms (historical; see the 2026-07-06 resolution above):** +1. **PortalSide portal polygons are IN the physics polygon set and we treat + them as solid.** Live: running the corridor, the seam crossing + `0x8A02016E → 0x8A02017A` (x≈85.25) records a wall hit with normal + (−1,0,0) — straight against the movement (`launch-175-verify2.log:42858`). + Dat (`Issue137CorridorSeamInspectionTests`): cell 0x8A02016E's portals to + 0x011E (polys 1/3/5, flags=**PortalSide**, no ExactMatch) are PRESENT in + `CellStruct.PhysicsPolygons` — every ExactMatch portal in the same cell is + absent from the physics set. The cell's rotation maps those local ±Y portal + planes to world ±X — the phantom mid-corridor wall. Retail must honor the + portal's SIDE (pass from one side / solid from the other, or pass when the + neighbor is loaded); we collide with the raw polygon unconditionally. + **Oracle findings so far (2026-07-05 evening — greps done, question + OPEN):** `CCellStruct::UnPack` (0x00533d00) loads physics_polygons + + physics_bsp verbatim — NO portal-poly stripping at load; + `CPolygon::pos_hits_sphere`/`hits_sphere`/`polygon_hits_sphere_slow_but_sure` + (0x005394f0/0x00539540/0x00538a10) are pure geometry — no portal check; + `CCellPortal` (0x0053bab0) carries portal→CPolygon ptr + portal_side + + exact_match but nothing in the BSP test chain consults it. So retail's + passability for a PortalSide physics poly is NOT a load filter and NOT a + poly-level flag — remaining candidates: the transit/membership order + makes the sphere test the NEIGHBOR cell first (never hitting the portal + poly from the passable side), or a sidedness interaction + (stippling=NoPos + approach direction). NEXT: cdb-attach retail at this + exact corridor (0x8A02016E→011E portals) per the CLAUDE.md step −1 + protocol — the decomp alone hasn't settled it. +2. **The stale sliding normal then wedges all forward motion** (the #116 + slide-response family): after the single seam hit, EVERY subsequent + forward resolve returns `ok=False hit=no` with zero advance — the + body-persisted SlidingNormal (−1,0,0) projects the +X offset to exactly + zero in AdjustOffset, aborting at step 0 BEFORE any collision test could + update the state — an ABSORBING wedge escaped only by strafing ("push + through on the side").

The degradation is specifically on the **outbound** side: what acdream sends to ACE for relay to other clients. - -**Root cause / status:** - -Unverified. The likely culprits, ranked by suspected probability: - -1. **AutonomousPosition heartbeat cadence.** `memory/project_retail_motion_outbound.md` notes acdream's fixed 200 ms heartbeat is a probable retail mismatch. Retail's `CommandInterpreter::SendPositionEvent` gates on transient_state (Contact + OnWalkable + valid Position) and may broadcast at a different cadence — fewer / more / variable. If acdream sends too rarely, observer dead-reckons too long between updates and visibly stutters when each AutoPos arrives. -2. **MoveToState send conditions.** `PlayerMovementController.cs:813-840` decides when a fresh MoveToState fires (state-change detection). If important transitions are missed (e.g., direction changes that don't flip ForwardCommand/SidestepCommand), the observer's last-known motion stays stale and AutoPos updates blip the body to the new authoritative position. -3. **InstanceSequence / ObjectMovement sequence counters.** ACE rejects out-of-order packets. If acdream's sequence stamping is off, ACE silently drops some packets; observer dead-reckons through the gap. -4. **Velocity field absent on AutoPos.** ACE relays UPs without HasVelocity for player characters (per `OnLivePositionUpdated` comment).

The bug reopened 2026-06-11 when a second root cause surfaced (dictionary-referenced-but-undrawn BSP polys drawn that retail never draws); per the user's mandate this was folded into the holistic building-render port effort (#113/#114/#108/#109/#99, charter at `docs/research/2026-06-11-building-render-holistic-port-handoff.md`), which shipped as part of the broader render-pipeline redesign (Option A) closed 2026-06-12. ## #111 — ACE-mutated indoor restores: transparent interior / wrong placement at login — [DONE 2026-06-10 · 5f1eb7c + 5706e0e + 2735695] @@ -5818,6 +7606,186 @@ Regen workflow: `py tools/pdb-extract/pdb_extract.py refs/acclient.pdb`. The com **Commit:** `feat(player): #5 PlayerDescription parser — Stam/Mana via attribute block` **Resolution:** First attempt (commit `d42bf57`) used `AppraiseInfoParser` for `PlayerDescription (0x0013)` — wrong wire format. ACE source confirmed via `GameEventPlayerDescription.WriteEventBody`: PlayerDescription is hand-written (DescriptionPropertyFlag-driven property hashtables, vector flags, attribute block, skills, spells, options/inventory tail) — distinct from `IdentifyObjectResponse (0x00C9)`'s `AppraiseInfo.Write`. Pivoted to a real port: new `PlayerDescriptionParser.cs` that walks property hashtables (Int32/Int64/Bool/Double/String/Did/Iid + Position) gated on the property flags, then reads vector flags + has_health + the attribute block where vitals 7/8/9 carry `ranks/start/xp/current`. Also redesigned `LocalPlayerState` to track per-vital snapshots (replacing the sentinel-API of attempt 1) plus per-attribute snapshots, with `GetMaxApprox` applying the retail formula `vital.(ranks+start) + attribute_contribution` (Endurance/2 for Health, Endurance for Stamina, Self for Mana). Live verified: `+Acdream` shows three bars; ~95% reading on Stam/Mana traced to active buff multipliers (filed as #6). Wire-port also added `PrivateUpdateVital (0x02E7)` + `PrivateUpdateVitalCurrent (0x02E9)` for delta updates per holtburger `UpdateVital`. ~700 LOC C#, 30+ new tests. +## #59 — WorldPicker 5m fixed-radius could over-pick at tight thresholds (M1-deferred polish) + +**Status:** DONE (2026-07-09, user-confirmed via memory during an issues-triage pass — not independently re-verified this session). +`WorldPicker.Pick` used a hardcoded 5m sphere around every candidate regardless of the entity's actual size, relying on the `ServerGuid==0` skip filter plus closest-wins logic to avoid mis-picks.

Fixed by Phase G.3a: `TeleportArrivalController` holds the position snap until the destination landblock/cell hydrates (`7947d7a`/`aca4b46`/`f22121b`), plus the validated-claim landblock-prefix fix (`2ce5e5c`) and a login-spawn recenter fix (`47ae237`) for the sibling case of logging in already inside a dungeon.

This was the founding bug behind the full render-pipeline redesign (Option A, one `DrawInside(viewer_cell)` traversal — see `docs/research/2026-05-31-render-architecture-reset-handoff.md`), closed as part of the broader #119/#128 render arc (2026-06-12); see `project_render_pipeline_digest.md`. + +--- + +## #103 — Phase A8.F portal-frame indoor rendering broken at runtime (visual-gate failure) + +**Status:** DONE (2026-07-09, user-confirmed via memory during an issues-triage pass — not independently re-verified this session). +The A8.F two-pipe (inside/outside) portal-frame renderer (`ACDREAM_A8_INDOOR_BRANCH=1`) was abandoned wholesale rather than fixed in place — Phase U (Unified Render Pipeline, 2026-05-30) deleted the broken `RenderInsideOut` two-pipe path and replaced it with the single unified retail PView portal-visibility pipeline that the render digest now treats as canonical.

User confirms this no longer reproduces. Files: `TerrainModernRenderer.cs`, `terrain_modern.frag`. + +--- + +## #154 — Dungeon interiors still read too dim vs retail (torch-sparse stretches + per-vertex bake) + +**Status:** DONE (2026-07-09, user-confirmed via memory during an issues-triage pass — not independently re-verified this session). +After the initial indoor-lighting fixes (`0d8b827`/`57c2ab7`) dungeons were brighter than the old flat-0.2 ambient but still trailed retail, especially in torch-sparse corridors. User confirms this is now resolved — consistent with the same-day A7 dungeon-lighting root-cause work (the "463>128 light cap" fix in the most recent commit history) that closed the sibling #93/#80 lighting issues. + +--- + +## #83 — Indoor multi-Z walking broken (cellars, 2nd floors, intermittent falling-stuck) + +**Status:** DONE (2026-07-09, user-confirmed via memory during an issues-triage pass — not independently re-verified this session). +Walking down into cellars and on 2nd floors was broken (stuck/falling); root cause was `TryFindIndoorWalkablePlane` synthesizing a fresh `ContactPlane` every frame instead of retaining the previous frame's plane like retail. User confirms this is resolved, consistent with the later A6.P4 per-cell collision architecture (shipped 2026-06-11) and the subsequent #137/#171/#182 physics fixes that completed the retail-faithful collision port this issue was blocked on. + +--- + +## #88 — Indoor static objects vibrate (bookshelves, open furnaces) + +**Status:** DONE (2026-07-09, user-confirmed via memory during an issues-triage pass — not independently re-verified this session). +Static cell objects (bookshelves, open furnaces) showed per-frame transform jitter, suspected sub-step state corruption or floating-point drift in per-part transform recomputation. User confirms this no longer reproduces, likely resolved alongside the A6.P4 physics architecture and subsequent entity-transform stabilization work. + +--- + +## #89 — Port BSPQuery.SphereIntersectsCellBsp for retail-faithful CheckBuildingTransit + +**Status:** DONE (2026-07-09, user-confirmed via memory during an issues-triage pass — not independently re-verified this session). +`CellTransit.CheckBuildingTransit` used a radius-less point-in-BSP test instead of retail's sphere-vs-BSP `CCellStruct::sphere_intersects_cell`, making outdoor→indoor entry fire ~sphereRadius deeper into doorways than retail. User confirms this is resolved, consistent with the A6.P4 per-cell shadow-list collision architecture (shipped 2026-06-11) which ported retail-faithful building-transit checks. Files: `src/AcDream.Core/Physics/CellTransit.cs`, `BSPQuery.cs`. + +--- + +## #134 — Player "lags downward" instead of gliding along a dungeon ramp edge + +**Status:** DONE (2026-07-09, user-confirmed via memory during an issues-triage pass — not independently re-verified this session). +Running along a dungeon ramp's edge produced a downward "lag" instead of a slide along the slope tangent, surfaced by the #133 connector-cell physics fix exercising the ramp's collision for the first time. User confirms this is resolved, consistent with the later CSphere/CCylSphere collision-family ports (#172, #182) and the general slide-response work tracked under #32/#116. + +--- + +## #46 — Retail observer of acdream sees blippy / laggy movement + +**Status:** DONE (2026-07-09, user-confirmed via memory during an issues-triage pass — not independently re-verified this session). +A retail client observing acdream's locally-driven `+Acdream` character saw stepped/blippy movement, suspected `AutonomousPosition` heartbeat cadence or `MoveToState` state-change-detection mismatches on the outbound path. User confirms this is resolved — matches the L.2b outbound wire-parity work per `project_retail_motion_outbound.md`. + +--- + +## #122 — Windows oscillate between background and the correct outside view when entering houses + +**Status:** DONE (2026-07-09, user-confirmed via memory during an issues-triage pass — not independently re-verified this session). +Windows flickered between the background/skybox and the correct outside view while entering houses (the #109 oscillation family localized to windows at the outdoor→interior root flip). User confirms this is resolved, consistent with the render-pipeline redesign (Option A, one `DrawInside(viewer_cell)`) that closed the broader #119/#128 flap family on 2026-06-12. + +--- + +## #123 — Buildings transiently disappear when running close past them + +**Status:** DONE (2026-07-09, user-confirmed via memory during an issues-triage pass — not independently re-verified this session). +Whole buildings transiently vanished when the player ran close past them at the outdoor root, suspected frustum pre-gate or stencil-punch interaction at close range. User confirms this is resolved, consistent with the render-pipeline redesign (Option A) that closed the broader #119/#128 flap family on 2026-06-12. + +--- + +## #179 — Lightning flash has no indoor gate (dormant until weather strobes ship) + +**Status:** DONE (2026-07-09, user-confirmed via memory during an issues-triage pass — not independently re-verified this session). +`mesh_modern.frag` added the lightning-flash term to every fragment (including sealed-dungeon interiors) with no indoor gating, latent until weather strobes ship. User confirms this is resolved — the flash term is now gated for `playerInsideCell` frames (or zeroed at the `SceneLightingUbo` build), matching retail's flat indoor ambient with no storm terms. + +--- + +## #65 — Local player doesn't turn to face target on close-range Use + +**Status:** DONE (2026-07-09, user-confirmed via memory during an issues-triage pass — not independently re-verified this session). +ACE's close-range Use path sends a `MovementType=8 TurnToObject` motion that acdream's `OnLiveMotionUpdated` didn't handle, so the local player completed the Use without visibly turning to face the target. User confirms this is resolved, consistent with the R4/R5 `MoveToManager` arc that ported retail's TurnTo handling for local and remote entities (superseding the older `RemoteMoveToDriver`). + +--- + +## #66 — Local + remote rotation: player flips back, NPCs don't turn + +**Status:** DONE (2026-07-09, user-confirmed via memory during an issues-triage pass — not independently re-verified this session). +Two related rotation bugs: the local player's facing snapped back after auto-walk arrival, and NPCs didn't turn to face the player on `MovementType=8 TurnToObject` motions (acdream only handled `MovementType=6 MoveToObject`). This issue explicitly superseded #65 as the broader TurnToObject-handling ticket. User confirms both are resolved, consistent with the R4/R5 `MoveToManager` arc's retail-faithful TurnTo port for local and remote entities. + +--- + +## #96 — Per-tick PhysicsEngine.ResolveWithTransition CP seed (retail divergence) + +**Status:** DONE (2026-07-09, investigated this session). +#96 was never a plain bug to fix — by 2026-05-22 (commits `892019bc`/`f8d669be`) the project determined the per-tick `ContactPlane` seed at `PhysicsEngine.cs` is load-bearing (BSP step_up on the last stair step depends on it) and formally reclassified it as an accepted retail divergence rather than a defect. It's tracked today as register row **IA-1** in `docs/architecture/retail-divergence-register.md` (retail: `CTransition::init`, pc:272547) rather than as an open bug. The code today still matches the issue's description exactly (verified at `PhysicsEngine.cs:979-1010`), so nothing was "fixed" in the traditional sense — the issue was superseded by the divergence-register entry as its permanent home. + +--- + +## #60 — `obstruction_ethereal` retail downstream path not ported (M2 combat-HUD impact) + +**Status:** DONE (2026-07-09, investigated this session). +Fixed by `3361a8d7` and `dc1e9270` (2026-06-24). `CollisionExemption.ShouldSkip` now requires both `ETHEREAL_PS` and `IGNORE_COLLISIONS_PS` for the Gate-1 exempt; ETHEREAL-alone now sets `SpherePath.ObstructionEthereal` and flows through BSP/Sphere/Cylinder consume sites matching retail pc:276782/276806/276989/321692/324573. Divergence-register row AD-7 retired same commit. `ObstructionEtherealTests.cs` passes 11/11. + +--- + +## #68 — Remote players don't stop running animation on auto-walk arrival + +**Status:** DONE (2026-07-09, investigated this session). +The mechanism named as the suspect in #68 (`RemoteMoveToDriver`'s arrival handling not flipping the animation cycle to Ready) was deleted wholesale in commit `7016b26c` (R4-V4, 2026-07-03), replaced by a verbatim-ported retail `MoveToManager` for every remote. The same day, commit `c2dc1a88` (R4-V5) fixed exactly the class of bug #68 describes: `StopCompletely` (which `MoveToManager`'s arrival path calls) wasn't reaching the entity's `AnimationSequencer` at all — it's now wired through `IInterpretedMotionSink.StopCompletely()` → `MotionTableDispatchSink` → `sequencer.PerformMovement(StopCompletely())`, confirmed live-wired for remotes in `GameWindow.EnsureRemoteMotionBindings`. No commit references "#68" explicitly and no user visual re-verification of this specific scenario is on record post-fix — recommend a spot-check (retail player auto-walking to an NPC, watched from acdream) if it resurfaces. + +--- + +## #87 — Drop WB fork patch by switching to PrepareEnvCellGeomMeshDataAsync + +**Status:** DONE (2026-07-09, investigated this session). +Superseded by Phase O (2026-05-21, dropped the `WorldBuilder.Shared`/`Chorizite.OpenGLSDLBackend` project references entirely — there's no more forked submodule to patch/revert) and Phase A8 (2026-05-28, shipped `EnvCellRenderer.cs` which already calls the narrow `PrepareEnvCellGeomMeshDataAsync(geomId, environmentId, cellStructure, surfaces)` entry point at `EnvCellRenderer.cs:355`, using the bit-32-tagged synthetic geom id the issue proposed). `ObjectMeshManager.cs`'s bounds/type dispatch now branches on resolution type before calling `TryGet`, so the blind `TryGet` bug is structurally gone. `EnvCellRenderer` remains the live production cell-rendering path under Phase U as of commit `6aabe0b5` (Jul 6 2026). Note: a second, unrelated, already-DONE issue also uses the heading `## #87` elsewhere in this file (a pre-existing numbering collision, left untouched). + +--- + +## #126 — Outdoor spawn claim on a building roof is grounded THROUGH the roof to terrain (transparent-interior spawn) + +**Status:** DONE (2026-07-09, investigated this session). +Fixed same-day as filed (2026-06-11) by commit `120aeff7` "RETAIL-CORRECTED: restores commit the server Z — retail never re-derives position from surfaces" (superseding an earlier same-day attempt `b94a7e80` that the user caught as retail-divergent). The outdoor zero-delta-restore branch in `src/AcDream.Core/Physics/PhysicsEngine.cs` now commits the claim's Z verbatim (matching retail's `CPhysicsObj::SetPositionInternal`, 0x00515bd0) instead of unconditionally grounding to terrain, eliminating the roof-to-interior warp. Verified present, unmodified, at HEAD. + +--- + +## #4 — Sky horizon-glow disabled (fog-mix skipped on sky meshes) + +**Status:** DONE (2026-07-09, investigated this session). +The literal bug as filed — fog-mix skipped on sky meshes — is no longer true. Commit `97fc1b51` (2026-04-27) re-enabled sky fog using a retail-cited 3D range-fog formula (`docs/research/2026-04-23-sky-fog.md`, which root-caused retail's actual horizon-glow mechanism: sky domes saturate to `WorldFogColor` by design because their intrinsic radius sits near/past keyframe FogEnd — same fog path as terrain, no special sky-only rule needed). Author noted user visual verification against retail screenshots; the fix has shipped unmodified for 2.5+ months through several subsequent commits. Follow-up: the `SKY_FOG_FLOOR=0.2` mitigation clamp layered on top still lacks a divergence-register row. + +--- + +## #81 — Static building stabs don't react to atmospheric lighting changes + +**Status:** DONE (2026-07-09, investigated this session). +Fixed by the A7 lighting rework, specifically A7 Fix D (`0980bea4`, `cf627933`, `c62da825`, `b7d655bc`, 2026-06-18/19). That work split the previously-unified lighting shader into an explicit object-path (`uLightingMode=0`) vs EnvCell-interior-path (`uLightingMode=1`): building exterior shells (stabs, `IsBuildingShell`/`ParentCellId==null`) are object-path entities and now read the same per-frame `SceneLighting` UBO (sun direction/color + ambient, rebuilt every frame from the live `SkyKeyframe`) that terrain and scenery already consumed — so stabs now darken/brighten in lockstep with the day/night cycle by construction. No dedicated visual re-check specific to stabs-vs-daycycle is on record, but the code mechanism the issue blamed no longer exists. + +--- + +## #33 — Live entity collision shape collapses to one cylinder + +**Status:** DONE (2026-07-09, investigated this session). +The described mechanism (live entities collapsing to one root-centered cylinder) no longer exists. `RegisterLiveEntityCollision` (`GameWindow.cs:4244`) now builds a multi-shape list via `ShadowShapeBuilder.FromSetup` — one shape per CylSphere, Sphere, and BSP-bearing Part — and registers via `RegisterMultiPart` (A6.P4 Task 7, `ca9341c2`). The retail `CSphere` and `CCylSphere` collision families were ported verbatim in `78e57581` (sphere primitive), `6ab26989` (fix #172, CCylSphere family), and `96ae2740` (fix #182, CSphere family, retires TS-45). The remaining `setup.Radius` single-cylinder path is now a deliberately-audited fallback used only when no other shape data exists. `tests/AcDream.Core.Tests/Physics/ShadowShapeBuilderShapeSourceTests.cs` covers both a multi-shape object and a live-creature case. + + + + + + + + + + +``` + +NOTE: `Chorizite.DatReaderWriter` flows transitively via AcDream.Core.

TL;DR + +Dungeons don't work because of **one timing+placement gap on one code path**, +not a terrain-less-pipeline rewrite. A dungeon landblock (e.g. `0x0125`, the +Holtburg-area meeting hall) is a **flat-terrain** landblock (`LandBlock` +present, all-zero heights) + 71 EnvCells + no buildings — it already streams, +renders, and collides through the existing pipeline. The teleport-arrival +handler snaps the player **before** that landblock has streamed in, so Resolve +falls back to the resident Holtburg blocks and lands the player in ocean. + +The fix is retail's own shape: **hold the player in portal space until the +destination cell is hydrated, then place into the EnvCell** — reusing the +#107/#111 login machinery — and then layer retail's portal-tunnel visual +(`TeleportAnimState`) on top. We ship it in four installments, gated by one +visual acceptance test. + +--- + +## 1. Corrected root cause (verified) + +### 1.1 The "terrain-less landblock" framing is WRONG (dat-verified) + +A prior research pass assumed dungeon landblocks have no `LandBlock` record, so +`LandblockLoader.Load` returns null and the whole streaming/render/physics +pipeline needs terrain-less support. **A direct dat probe +(`DungeonLandblockDatProbeTests`, committed) refutes that:** + +``` +0x0125 (dungeon): LandBlock 0x0125FFFF PRESENT, Height[81] allZero=True (flat) + LandBlockInfo: NumCells=71, Buildings=0, Objects=0 + EnvCells 0x0100.. present (the 71 dungeon rooms) +0xA9B4 (Holtburg): LandBlock PRESENT, heights non-zero; NumCells=123, Buildings=12, Objects=114 +``` + +A dungeon landblock is a **flat-terrain landblock** (lowest/"ocean" terrain +height index) **plus its EnvCells, no buildings/objects**. `LandblockLoader.Load` +returns a valid flat landblock; the terrain mesh builds a flat plane; +`PhysicsEngine.AddLandblock` gets a valid flat `TerrainSurface`. **The existing +pipeline already streams a dungeon landblock.** This matches ACE's `IsDungeon` +(all heights 0 + `NumCells > 0` + no buildings — `Landblock.cs:575`) and the +single-landblock rule (`Player_Tick.cs:548-560` forbids moving between dungeon +landblocks without a teleport — so "multi-landblock dungeon LOD" is moot). + +### 1.2 The real blocker: teleport TIMING + PLACEMENT + +`OnLivePositionUpdated` (`src/AcDream.App/Rendering/GameWindow.cs:4877-4961`) +detects teleport arrival as **any** player position update while in PortalSpace +(correct, per #107), then **unconditionally**: + +1. Recenters streaming to the destination landblock (`_liveCenterX/Y`, `:4908-4925`). +2. **Immediately** calls `_physicsEngine.Resolve(destPos, destCell, …)` to snap + the player (`:4927-4931`) — **before the destination landblock has streamed in**. +3. Snaps entity + controller (`:4935-4939`), exits PortalSpace (`:4950`), sends + `LoginComplete` (`:4953-4959`). + +Because the dungeon landblock isn't resident yet, Resolve can't find the +destination cell, falls back to an **outdoor scan against the still-resident +Holtburg landblocks**, and snaps to `0xA9B3000E` (Holtburg's south edge — local +`(30,−60)` maps into the block south of the A9B4 spawn). Streaming then shifts +the frame out from under the player → they slide south into ocean. ACE logs the +matching `failed transition for +Acdream from 0x01250126 … to 0xA9B0000E …` +chain (captured in `launch-dungeon-diag.log`). + +**There is no hold-until-hydration on the teleport-arrival path.** The #107 +*login* path directly above it (`GameWindow.cs:1010-1024`) HAS exactly this gate; +the teleport path doesn't. + +--- + +## 2. Grounded seam facts (the design rests on these) + +All five verified against current code this session (high confidence). + +### 2.1 Teleport-arrival + PortalSpace FSM +- `OnTeleportStarted` (`GameWindow.cs:~4971-4976`) — on `PlayerTeleport (0xF751)` + sets `_playerController.State = PlayerState.PortalSpace`, freezing movement. +- `PlayerMovementController.Update` (`PlayerMovementController.cs:840-854`) returns + a zero-movement result while `State == PortalSpace` — **PortalSpace already + doubles as the input-freeze.** It can equally serve as the hydration-wait gate. +- Exit is **only** via the arrival detection in `OnLivePositionUpdated` + (`:4880`). No timeout, no cell-hydration gate today. + +### 2.2 #107/#111 login machinery (directly reusable) +- `PhysicsEngine.IsSpawnCellReady(cellId)` (`PhysicsEngine.cs:468-472`): outdoor + (`cellId & 0xFFFF < 0x0100`) → always ready; indoor → `DataCache.GetCellStruct(cellId) + is not null` (the cell's physics BSP has hydrated). +- `IsSpawnClaimUnhydratable(claim)` (`GameWindow.cs:11728-11748`): fetches the dat + `LandBlockInfo` at `(lb & 0xFFFF0000) | 0xFFFE`; a claim whose low word is + `>= 0x0100 + NumCells` (or `NumCells==0`) can **never** hydrate → reject fast + (distinguishes a bogus claim from a not-yet-streamed one). +- #107 login hold (`GameWindow.cs:1010-1024`): `isSpawnGroundReady` waits for + terrain AND (claim outdoor OR `IsSpawnCellReady` OR `IsSpawnClaimUnhydratable`). + No timeout today (login can afford to wait forever; teleport cannot — see §5). +- #111 validated-claim placement (`PhysicsEngine.cs:626-646`): when + `snapDiag (zero-delta) && adjustedFound && indoor`, place via + `WalkableFloorZNearest` (`:383-406`) — projects Z onto the claim cell's **own + physics walkable polygons** (`normal.Z >= PhysicsGlobals.FloorZ`, 0.6642), + cell-local, nearest to the reference Z. Returns `null` if the cell isn't + hydrated → falls through to the legacy `bestCell` scan (**the ocean bug**). +- **The teleport-arrival Resolve call is already the same shape as login entry.** + The gate only needs to sit in front of it; no change to Resolve or + WalkableFloorZNearest. (Both already key on the full prefixed cell id + + indoor/outdoor.) + +### 2.3 Streaming far recenter (works as-is) +- `StreamingRegion.RecenterTo` (`StreamingRegion.cs:180-283`) recomputes the + near/far Chebyshev window **from scratch** around the new center — a 42 km jump + is treated identically to a 1-step move. No incremental-movement assumption. +- Drain: `StreamingController` applies ≤ `MaxCompletionsPerFrame` (default 4) + results/frame; `ApplyLoadedTerrainLocked` (`GameWindow.cs:5941-6150`) does GPU + upload + cell-visibility registration + AABB + `PhysicsEngine.AddLandblock` + + EnvCell/portal registration. Estimate: **~7-8 frames (~120-130 ms)** to hydrate + a 5×5 near window; physics ready +1-2 frames. +- Recenter keeps the old neighborhood until hysteresis unload (NearRadius+2 + demote, FarRadius+2 unload), so the player isn't instantly stranded. +- **New code needed:** reuse the #107 login-gate **terrain-ready signal** + `_physicsEngine.SampleTerrainZ(x,y) is not null` (non-null once the destination + terrain landblock has applied) — no separate "landblock applied" query is + required. Plus dest-coord validation (reject out-of-world coords — a malformed + portal dest would otherwise leave the player in an invisible, unloadable + landblock). + +### 2.4 EnvCell hydration coupling (latent landmine — decouple) +- In `BuildInteriorEntitiesForStreaming` (`GameWindow.cs:5564-5651`), both + `BuildLoadedCell` (the portal-visibility node) **and** + `_physicsDataCache.CacheCellStruct` (the physics BSP) sit **inside** the render + guard `if (cellSubMeshes.Count > 0)` (`:5602`). A cell whose render mesh is empty + (`CellMesh.Build` returns nothing — e.g. all-untextured/`Stippling.NoPos` polys) + silently gets **no visibility node and no collision**, even if it has walkable + physics polygons. `CellTransit.FindTransitCellsSphere` then `GetCellStruct → null + → continue` (silently skips it) → fall-through-floor. +- A normal dungeon *room* has textured walls → non-empty submeshes → the guard + passes, so this is **probably not the meeting-hall blocker** — but it is a real + correctness landmine for any geometry-less collision cell, and decoupling is + cheap and retail-correct (physics/visibility do not depend on visible geometry). + **Fix:** gate `CacheCellStruct` on `cellStruct.PhysicsBSP != null` and + `BuildLoadedCell` on `cellStruct != null`, independent of the render submesh + count. (`CacheCellStruct` already early-returns on null BSP internally — + `PhysicsDataCache.cs:172` — so moving it out is safe.) + +### 2.5 #95 — dungeon portal-graph visibility blowup (RE-ASSESSED: likely superseded) +- ISSUES.md #95 (`888-913`): on a 2026-05-21 **A6.P1 scen5 (Town Network hub)** + trace, `visibleCells` per cell exploded to 135-145 with spurious cells from + landblocks `0x020A`/`0x0408` (other dungeons). Its "Files" point at the WB + `EnvCellRenderManager`/`VisibilityManager` + the Streaming cell-cache. +- **That code path was DELETED by the T1-T6 render rewrite (2026-06-11)** (T4: + "per-frame ACME BFS deleted… InteriorRenderer/DrawPortal deleted"). The current + flood, `PortalVisibilityBuilder.Build`, (a) confines neighbors to the camera + cell's landblock (`lbMask = cameraCell.CellId & 0xFFFF0000`, `:131`) and (b) has + **enqueue-once termination** (`queued` HashSet, `:165` — "at most N cells are + ever processed"). Since AC dungeons are single-landblock, that confinement is + *correct*, and the cross-landblock 135-cell blowup **structurally cannot + reproduce**: a single-landblock flood visits ≤ `NumCells` distinct cells (71 for + the meeting hall). +- **Verdict (pre-gate, 2026-06-13 AM):** #95's evidence is stale, from a deleted + path; the current pipeline looked bounded. Treated #95 as likely superseded. +- **⚠️ GATE CORRECTION (2026-06-13 PM — #95 is CONFIRMED LIVE):** the G.3a visual + gate ran a real `PlayerTeleport` into the `0x0007` dungeon (Town Network). The + core hold+place worked (player grounded on the dungeon floor, z=0 — no ocean), + but **WB-DIAG exploded to entSeen=6.5M / instances=9.1M / drawsIssued=590K per + frame** (vs. 3345 / 4667 at Holtburg), with a flood of `[mesh-miss] 0x000100xxxx` + interior re-requests → the dungeon renders as "thin air." **#95 reproduces under + the current Option-A pipeline.** The "bounded flood" reasoning was wrong for the + `0x0007` dungeon (the grounding agent's "still live" verdict was correct; this + doc over-discounted it). **G.3b is now REQUIRED, not conditional** (§3.2). The + retail-faithful fix shape stands: port `CEnvCell::grab_visible_cells` (:311878) + stab_list bounding — a `seen_outside==0` cell walks ONLY its `stab_list`. + +--- + +## 3. The plan (Approach C — phased full-G.3) + +Each installment lands a **complete retail behavior** (the BR-2 half-port +lesson). The visual gate sits as early as possible, right after the core. + +### 3.1 G.3a — Core teleport-into-dungeon (the blocker) + +**Goal:** teleporting into the meeting-hall dungeon lands the player standing in +the dungeon cell, on the floor, with walls blocking — no ocean, no ACE +`failed transition` spam. + +**New component — `TeleportArrivalController`** (`src/AcDream.App/World/`): +- Owns a small phase: `Idle / Holding / Placing`, plus `_pendingArrival` + `(destPos, destCellId, deadline)`. +- Lives outside `GameWindow` (Code Structure Rule 1: no new feature bodies in the + god-object). `GameWindow.OnLivePositionUpdated` hands the arrival to it and + calls its per-frame `Tick`; `GameWindow` keeps only the wiring. +- Unit-testable in isolation (no GL, fake readiness predicate + fake Resolve). + +**Control flow (replaces the unconditional snap at `GameWindow.cs:4927-4950`):** +1. On arrival update in PortalSpace: validate `destCellId`'s landblock coords are + in-world; recenter streaming + prioritize-load the dest landblock (existing + path); stash `_pendingArrival`; enter `Holding`. Re-send `LoginComplete` + immediately (holtburger-conformant — `messages.rs:434`; do **not** wait for + assets to send it). +2. Each frame in `Holding`, evaluate the **readiness predicate**: + - `IsSpawnClaimUnhydratable(destCell)` → impossible claim: stop holding, place + via the safety-net demote (loud log), exit PortalSpace. + - `now > deadline` (timeout, ~10 s) → force-snap via safety-net demote + loud + log, exit PortalSpace. (See §5 — failure-surfacing, not symptom-masking.) + - `SampleTerrainZ(destPos) != null && (outdoor || IsSpawnCellReady(destCell))` + → ready: go to 3. + - else stay frozen, retry next frame. +3. `Placing`: call the **existing** `Resolve(destPos, destCell, Vector3.Zero, …)`. + Because the cell is now hydrated, Resolve takes the #111 validated-claim branch + → `WalkableFloorZNearest` grounds the player on the EnvCell floor. Snap entity + + controller (existing `:4935-4939` code), exit PortalSpace, resume input. + +**Readiness predicate — reuse the #107 login triplet (no new query).** The +hold gates on exactly the three checks the login auto-entry gate already uses +(`GameWindow.cs:1010-1024`), evaluated against the teleport's `(destPos, +destCell)` instead of the spawn claim: `SampleTerrainZ(destPos.X, destPos.Y) is +not null` (destination terrain applied) ∧ (outdoor cell OR +`IsSpawnCellReady(destCell)`); `IsSpawnClaimUnhydratable(destCell)` short-circuits +an impossible claim to immediate placement. This reuses proven, validated code +rather than introducing a parallel "landblock applied" query. + +**Dest-coord validation:** in `OnLivePositionUpdated`, reject a destination whose +`(lbX, lbY)` is out of the world grid before recenter; log + abort the teleport +hold rather than recenter to a phantom block. + +**Hydration decouple (§2.4):** move `BuildLoadedCell` + `CacheCellStruct` out of +the `cellSubMeshes.Count > 0` guard in `BuildInteriorEntitiesForStreaming`. Gate +each on its own non-null precondition. + +**Acceptance (G.3a):** the visual gate in §6. This gate also empirically settles +#95 (does the flood blow up?) and the hydration coupling (does collision work?). + +### 3.2 G.3b — #95 visibility bounding (REQUIRED — gate-confirmed 2026-06-13) + +**The G.3a gate confirmed the blowup** (9.1M instances/frame in `0x0007`), so this +is the next blocker, not a conditional follow-up. The dungeon will not render +until the portal-visibility flood is bounded to the dungeon's own cell adjacency. + +**Fix:** port retail `CEnvCell::grab_visible_cells` (`:311878`) — a cell with +`seen_outside == 0` loads ZERO terrain and walks ONLY its `stab_list` of adjacent +EnvCells; the portal graph is bounded by the dungeon's own cell adjacency, never a +radius / never the whole resident cell set. This is a render-pipeline change in +`PortalVisibilityBuilder` (the flap-/DO-NOT-RETRY-sensitive area) and needs its own +grounding + brainstorm before implementation (verify the dat carries the stab_list +and acdream's EnvCell loader parses it; confirm the `seen_outside` flag is read; +decide how it composes with the outdoor-root look-in floods). **NOT a wing-it +inline fix.** + +**Open question surfaced at the gate (possible Bug C):** even with Bug A fixed +(placement keeps the dungeon prefix, `2ce5e5c`), the dungeon's negative-local-Y +coordinate frame may cause the per-tick membership/landblock resolution to drift +(the ACE `movement pre-validation failed` spam). Re-gate after Bug A to see if it +persists; if so, fold the dungeon-coordinate membership handling into G.3b's +grounding (it is plausibly the same `seen_outside` / cross-landblock root as #95). + +### 3.3 G.3c — Portal-tunnel loading visual (faithful `TeleportAnimState`) + +**Goal:** the retail portal-space transition, ported faithfully (user decision +2026-06-13). Reconciles the older r09 §6 ("there is no loading screen") with the +named-retail decomp where this FSM actually lives. + +**Oracle:** `gmSmartBoxUI::BeginTeleportAnimation` (`004d6300`, named-retail line +218888) + the per-frame FSM (`219405-219774`). States: +`TAS_WORLD_FADE_OUT → TAS_TUNNEL_FADE_IN → TAS_TUNNEL / TAS_TUNNEL_CONTINUE → +TAS_TUNNEL_FADE_OUT → TAS_WORLD_FADE_IN → (off)`. `m_pPortalSpace` is a +`UIElement_Viewport` rendering the tunnel scene (creature-mode objects + +`DISTANT_LIGHT` + smartbox FOV; `SetVisible(1)` on enter, `SetVisible(0)` on the +`TAS_TUNNEL_FADE_OUT → TAS_WORLD_FADE_IN` edge at `219742-219747`). + +**Key architectural unification:** the `TAS_TUNNEL`/`TAS_TUNNEL_CONTINUE` **hold +state's exit gates on the same readiness predicate as G.3a** — retail's loading +visual and the hold-until-hydration gate are *one mechanism* (the tunnel is the +visual form of the hold). G.3a ships the bare PortalSpace freeze; G.3c wraps it +in the tunnel viewport + the fade FSM, exit-gated identically. + +**Port workflow:** grep-named → decompile `BeginTeleportAnimation` + the FSM → +pseudocode (durations, fade math, viewport scene construction) → port → test. +Detail deferred to the G.3c implementation phase; this spec fixes the design +(states, transitions, the readiness-gated hold) + the oracle pointers. + +### 3.4 G.3d — Recall game-actions + +Outbound **zero-payload** game-action builders (r09 §7.1): `TeleToLifestone +0x0063`, `TeleToHouse 0x0262`, `TeleToMansion 0x0278`, `TeleToMarketPlace 0x028D`, +`RecallAllegianceHometown 0x02AB`, `TeleToPkArena 0x0027`. The client only sends +the request; the server validates, plays the recall animation, then drives the +**same** `PlayerTeleport → UpdatePosition` arrival flow. + +Value: (1) doubles as the **easy test lever** for G.3a/G.3c — `/ls` triggers a +teleport with no portal-click choreography; (2) completes the recall UX (keybinds +exist; the wire sends + return handling did not).

The shipped path (D.2a) is an ImGui +overlay gated on `ACDREAM_DEVTOOLS=1` — a debugger aesthetic, intentionally +temporary. D.2b stands up the *retail-look* UI (the dormant `UiHost` tree) that +draws retail's actual dat assets, while the ImGui devtools path stays untouched. + +**The user's framing (2026-06-14):** AC's UI engine is Keystone — and Keystone +was *already* markup + stylesheet (KSML, an HTML-clone XML defined by `ksml.xsd`, ++ `controls.ini`, a CSS-like INI stylesheet). So "make it look + behave like +retail, but author it in a CSS/HTML-style way" re-expresses AC's own design in +its modern equivalent. + +**Approach decision (Approach C).** Three integration families were weighed: +(A) embed a real web engine (Ultralight/CEF), (B) a native HTML/CSS-subset lib +(RmlUi), (C) our own KSML-style markup + stylesheet over a retained-mode toolkit +on Silk.NET. **C chosen** for: zero external deps (keeps the native-AOT goal +intact), lowest memory (~3–10 MB vs CEF's 150–300 MB), full control, and maximal +faithfulness — it mirrors Keystone directly, and the retained-mode toolkit C +needs *already exists* (§0). + +This spec covers **Spec 1**: wire the scaffold + add the markup/stylesheet/sprite +gaps, proven end-to-end on **one** panel — the universal window frame wrapping +the live Vitals bars. + +## 2.

Slice/edge metrics are a **documented stopgap +constant** (with a divergence row) until the `LayoutDesc` tree is parsed +(sub-project 3). + +## 7. Markup + stylesheet model + +**Markup** mirrors `ElementDesc` 1:1 ([acclient.h:33693](../../../docs/research/named-retail/acclient.h)); +`MarkupDocument` parses it and **instantiates a `UiElement` subtree** (a +`UiNineSlicePanel` with child `UiLabel`/`UiMeter`/`UiButton`). Authoring shape: + +```xml + + + + + +``` + +This is the shape the future `LayoutDesc` importer will *emit*, so authoring and +imported formats converge. It is **not** KSML (rich-text, deferred). `{Binding}` +expressions resolve against a supplied binding object (the `VitalsVM`) via +reflection on the property name. + +**Anchor codes** are *defined* now (0=fixed, 1=stretch, 2=proportional-translate, +3=center, 4=proportional-scale — from `StateDesc::UpdateSizeAndPosition` +@`0x0069BF20`) but the **solver is deferred**: the Vitals window is fixed-size +(placed via the existing `UiElement.Left/Top`), so Spec 1 needs no solver. + +**Stylesheet.** A small INI loader parses `controls.ini` keyed by element-type +section, honoring `#AARRGGBB` (alpha-first) and `font://Face-Pt[-style]`. Cascade: +element-type defaults → per-element `class=` → inline attributes. **Optional** +(§10): absent AC install → source-verified `[title]`/`[body]` fallback tokens. + +## 8. VM binding (the Vitals slice) + +The vitals panel is a `UiNineSlicePanel` (chrome) containing a `UiLabel` (title) +and three `UiMeter`s. Each `UiMeter` holds a `Func Fill` bound to the +real `VitalsVM` ([VitalsVM.cs:67](../../../src/AcDream.UI.Abstractions/Panels/Vitals/VitalsVM.cs)): +`() => vm.HealthPercent`, `() => vm.StaminaPercent`, `() => vm.ManaPercent`. The +VM already does all server plumbing, so we do **not** re-derive vitals from the +retail `gmVitalsUI`/`CACQualities` decomp. + +`UiMeter.OnDraw` draws the empty bar (`ctx.DrawRect`), the filled portion as a +**partial-size rect** (`width = pct * Width`), and a centered `current/max` numeric +overlay (`Func Label`). **Retail's vitals ARE exactly this — three stacked +horizontal bars (confirmed against a live retail client 2026-06-14), NOT orbs.** +Colors: Health red, **Stamina gold** (the earlier `#10F0F0` cyan research note was +wrong), Mana blue. A `null` fill/label (pre-`PlayerDescription`) renders gracefully. +The remaining gap to pixel-retail is the **glassy gradient bar fill sprite** + the +**retail dat font** for the numbers (today the stub `BitmapFont` draws them) — both +polish, deferred to §15. + +The `VitalsVM` is constructed and given the player GUID the same way as today +([GameWindow.cs:1330](../../../src/AcDream.App/Rendering/GameWindow.cs) ctor, +:1984 `SetLocalPlayerGuid`); the retail-UI build path reuses that same VM +instance. + +## 9. Plugin contract (designed now, first consumer first-party) + +The plugin API is a day-1 constraint; plugin authors must be able to add retail +UI. The natural unit is a **`UiElement`/markup subtree added to `UiRoot`** (not +`IPanel`/`IPanelRenderer`, which is the ImGui devtools path). Spec 1 adds: + +- A small `IUiRegistry` (in `AcDream.Plugin.Abstractions`) — `void + AddMarkupPanel(string markupPath, object binding)` (and/or `void + AddElement(UiElement)` once a plugin-safe element surface is decided). For + Spec 1, `AddMarkupPanel` is enough. +- `IPluginHost` gains `IUiRegistry Ui { get; }` + ([IPluginHost.cs:8](../../../src/AcDream.Plugin.Abstractions/IPluginHost.cs) + has none today); `AppPluginHost` implements it + ([AppPluginHost.cs:5](../../../src/AcDream.App/Plugins/AppPluginHost.cs)). +- Because plugin `Enable()` runs in `Program.cs` **before** the GL window opens + ([Program.cs:55-60](../../../src/AcDream.App/Program.cs)), `AddMarkupPanel` + **buffers** registrations into a list that `GameWindow` drains into `UiRoot` + after `UiHost` is constructed. The threading/timing concern lives in the host; + the plugin call is unconditional. +- The first consumer is the first-party vitals panel (built directly in + `GameWindow`, not through the registry). Wiring an actual plugin-supplied markup + panel end-to-end is exercised by a smoke test but is otherwise the thin + follow-up. This task group is the **last** in the plan so the visible vitals + slice can land first if it slips. + +## 10. Confirmed decisions (approved 2026-06-14) + +1. **Render-only first slice.** `Tick` + `Draw` only; the `UiHost` input wiring + (`WireMouse`/`WireKeyboard`) is **not** connected to the existing Phase-K + `InputDispatcher` yet, so the close button isn't clickable and the window + isn't draggable. Rationale (corrected): the `UiRoot` input *machinery* already + exists — what's deferred is *integrating two input consumers* (routing + unconsumed `WorldMouseFallThrough` back to the game's dispatcher), which is its + own sub-phase. +2. **`controls.ini` optional.** Assume `C:\Turbine\Asheron's Call\` may or may not + exist. Add an `ACDREAM_AC_DIR` `RuntimeOptions` field; when absent, fall back + to the source-verified `[title]`/`[body]` token values. The build never fails + on a missing AC install. + +## 11.

Error handling & edge cases + +- **Missing/undecodable sprite** → `GetOrUpload` magenta fallback is visible; + Step 0 catches it. A null/zero DataID in markup logs a warning, draws nothing. +- **AC install absent** → `controls.ini` load skipped, baked fallback tokens used. +- **Vitals null percents** → empty bar (`UiMeter.Fill` returns null). +- **Window resize** → `UiHost.Draw` already sets `Root.Width/Height` to the + current screen size each frame ([UiHost.cs:61](../../../src/AcDream.App/UI/UiHost.cs)); + fixed-coord panels stay put. No DPI scaling (known out-of-scope gap). +- **Both toggles on** → ImGui Vitals and retail Vitals may both show (fine in dev). + +## 13. Testing + +- **`ControlsIni` parser** (pure, no GL) — unit tests for `#AARRGGBB`, `font://`, + cascade order.

It is retail's "HTML for windows."

Matches the project's + "behavior is retail" ethos. +3. **Structure = hybrid (Approach C).** Port each element type's render **algorithm** + verbatim from the decomp, onto our modern draw primitives. A single generic renderer + handles the trivial "stamp the sprite per draw-mode" types (the long tail, including + types not yet catalogued); dedicated widgets handle types with real behavior (meter, + text, scrollbar/chat, button). The decomp's render method for each type *decides* which + bucket it falls in — we do not guess. Faithfulness comes from porting the algorithms; + the hybrid is only about C# packaging. +4. **Coexistence, don't-delete.** `MarkupDocument` stays as the path for plugin/custom + panels (no dat layout). The existing widgets (`UiMeter`, `UiNineSlicePanel`, + `UiChatView`, `UiDatFont`) and primitives (tiling, scissor-fill, dat-font, nine-slice) + become the importer's behavioral renderers. + +## Architecture & data flow + +``` +RETAIL WINDOWS (data-driven from the dat) + client_portal.dat ─► LayoutImporter ─► UiElement tree ─► UiRoot ─► renderers ─► screen + (LayoutDesc 0x21..) │ (UiDatElement + + │ behavioral widgets) + ├─ resolve BaseElement / BaseLayoutId inheritance + ├─ walk ElementDesc tree → widget (hybrid factory) + └─ apply rect / anchors / states / media / props from the dat + + per-window Controller ─► binds LIVE data to elements by id (mirrors retail gm*UI) + WindowManager ─► open/close by layout id, z-order, focus, position persistence + +PLUGIN / CUSTOM PANELS (hand-authored, unchanged) + *.xml ─► MarkupDocument ─► UiElement tree ─► (same UiRoot + renderers) +``` + +Two input paths (dat importer for retail windows, markup for custom/plugin), one rendering +toolkit.

Format enumeration (Step 0 — foundational groundwork) + +Because we chose "full faithful," the first deliverable is a **documented map** of the +complete format, not code. Sources, cross-checked against each other: + +- **DatReaderWriter types** — `ElementDesc`, `StateDesc`, `MediaDesc*` and their enums + (`Type`, `DrawMode`, media kinds, state keys). Reflect/inspect as `dump-vitals-layout` + already does (props **and** fields). +- **Retail decomp** — the `UIElement_*` class hierarchy + each type's render method; the + property-key meanings; the **KSML keyword registrations** (the parser registers every + property name — the canonical vocabulary, e.g. `KW_DRAWMODE`, `KW_DURATION`, …). +- **Real layouts** — scan a sample of `LayoutDesc`s to confirm which Types/properties + actually occur and catch anything the above missed. + +Output: a reference doc mapping each `Type` → meaning + render method, each property key → +meaning, each `DrawMode` → behavior, and the inheritance rules. This doc drives every other +component and is committed alongside the importer. + +### 2. `LayoutImporter` + +Reads a `LayoutDesc` by id and returns a `UiElement` subtree: +- Walk the `ElementDesc` tree. +- For each element: resolve inheritance (§3), pick a widget via the factory (§4), set its + rect (`X/Y/W/H`), anchors (edge flags → `AnchorEdges`), z-order, states, media, and + properties from the (resolved) element. +- Recurse into children. +- Expose `FindElement(uint id)` on the result so controllers wire by id. + +Depends on: `DatCollection` (read layouts), the factory, the inheritance resolver, +`TextureCache.GetOrUploadRenderSurface` (sprites), `UiDatFont` (text). No GL itself — it +builds `UiElement`s; rendering stays in the toolkit. + +### 3. Inheritance resolution + +An element with `BaseElement`/`BaseLayoutId` inherits the base element's properties / states +/ media; the derived element overrides. Resolve by loading the base layout, finding the base +element, and merging (base first, then derived overrides) **before** instantiating. +Required even for vitals: the number-text element inherits its font/style from base layout +`0x2100003F`.

Per-window controllers (live-data binding) + +Mirror retail's `gm*UI` classes. A small controller per window grabs elements by id from the +imported tree and pushes live data in: `VitalsController` binds `HealthPercent` → meter fill, +`cur/max` → number text; `ChatController` binds the chat tail → the chat region. **This is +the only per-window code, and it is data wiring, not graphics.** Retail-faithful: e.g. +`gmVitalsUI::PostInit` grabs child meter elements by id and sets attribute `0x69` (fill). + +### 7. `WindowManager` + +`OpenWindow(layoutId, controller)` → import + attach to `UiRoot`, place at the dat's default +position (then persist user move/resize), manage z-order / focus / close. Orchestrates the +focus/drag/resize mechanics `UiRoot` already provides. + +### 8. States / expand / hover + +Each element carries its named states (`HideDetail`/`ShowDetail`, normal/hover/pressed) from +the dat; the active state selects which media draws.

NOTE: the shipped factory keys off the small *numeric* Types (1–0x12); the + item-slot/item-list are `UIElement` subclasses identified by a high class id, so the plan + must add a class-id dispatch branch (the class id is already surfaced — `ElementReader.Merge` + resolves it through the `BaseElement` chain, and `UIElement_UIItem` derives from + `UIElement_Field`/Type 3, so do NOT register numeric Type 3 — that stays chrome `UiDatElement`, + per the shipped toolkit's deliberate Type-3 rule). Behavioral **leaf** — overrides + `ConsumesDatChildren => true` so the importer does NOT build its dat sub-elements (it + reproduces them procedurally). +- **State:** `uint ItemId` (the bound weenie guid, retail `+0x5FC`). Phase 1 needs only this. + Quantity / selection / drag-accept / ghost / open-container overlay states are *structurally + reserved* (documented as later-phase hooks) but inert. +- **Render:** if `ItemId == 0` → draw the empty-slot sprite (the dat state `ItemSlot_Empty` + → `0x060074CF`, read from the element's states like every other `UiDatElement` sprite). Else + → draw the composited icon (§4.3) into the 32×32 cell. Phase 1 draws no quantity text / no + overlays. +- **Depends on:** the icon pipeline (§4.3), `UiRenderContext.DrawSprite`. + +### 4.2 `UiItemList` (new behavioral widget) — port of `UIElement_ItemList` (`0x10000031`) + +- **Location:** `src/AcDream.App/UI/UiItemList.cs`. +- **Registration:** `DatWidgetFactory` keyed off class id `0x10000031`. Behavioral leaf + (`ConsumesDatChildren => true`) — manages its `UiItemSlot` children procedurally. +- **Phase-1 API subset:** `AddItem(UiItemSlot)` / `Flush()` / `GetNumUIItems()` / + `GetItem(int)`. The toolbar uses 18 **single-cell** instances (one `UiItemSlot` each), so + the N-cell grid layout (column wrap, cell pitch) is NOT needed yet — deferred to the + inventory phase. A single-cell list just hosts at most one slot. +- **Depends on:** `UiItemSlot`. + +### 4.3 Icon pipeline (Approach A — faithful CPU pre-composite) + +- **Location:** `src/AcDream.App/UI/IconComposer.cs` (App layer — it touches GL texture + upload). Pure-decode helpers may live alongside `TextureCache`. +- **Behaviour:** port `IconData::RenderIcons` (407524). For a given item's icon ids, build a + single 32×32 BGRA composite on the CPU by alpha-compositing the layers bottom→top + (§3 list), apply the `ReplaceColor` palette tint to the custom-overlay layer, then upload + the result once as a GL texture and **cache it keyed by the icon-id tuple** (so identical + items share one composite). The slot draws one sprite. +- **Layer decode:** each layer id is a `0x06` RenderSurface decoded DIRECTLY (Portal/HighRes + `TryGet` → `SurfaceDecoder.DecodeRenderSurface(palette:null)`), the same path + `TextureCache.GetOrUploadRenderSurface` already uses — but composited on the CPU rather than + drawn as separate sprites. +- **Enum-mapper layers:** the type-default underlay (`GetByEnum(0x10000004, …)`) and effect + overlay (`GetByEnum(0x10000005, …)`) require reading the two DBObj enum-mapper tables. These + are bounded lookups (index → RenderSurface id); port them as part of this unit. If a mapper + proves more involved than the research suggests, the base + custom underlay/overlay layers + still composite correctly and the enum layers can land as a tight follow-up within the phase + (documented, not silently dropped). +- **Why pre-composite, not stacked draws:** the custom-overlay `ReplaceColor` tint is a + per-pixel palette operation, not a simple alpha-blend — it cannot be reproduced by a tinted + `DrawSprite`. CPU compositing is therefore the faithful path, and it's the shared spine for + all three panels, so it's built correctly once. +- **Depends on:** `DatCollection` (RenderSurface decode), GL texture upload. + +### 4.4 `CreateObject` icon extension + `ItemInstance` + +- **Location:** `src/AcDream.Core.Net/Messages/CreateObject.cs`, `src/AcDream.Core/Items/ItemInstance.cs`. +- **Change:** in `CreateObject.TryParse`, capture the `IconId` (currently discarded at + `CreateObject.cs:516`) — and the underlay/overlay/effect ids if present in the same block — + onto the parsed object so `ItemRepository` stores them on `ItemInstance` (fields already exist). +- **Planning delta (see the plan):** fact-gathering found this is wider than "just capture IconId." + acdream has NO `CreateObject`→`ItemRepository` wiring at all (the repo is populated only from + `PlayerDescription` with stub `ItemInstance`s), and `Parsed.Shortcuts` is parsed then discarded + in `GameEventWiring`. So the plan adds three small wiring pieces: capture IconId (Task 1), enrich + the repo from the `WorldSession.EntitySpawned` event (Tasks 2–3, `ItemRepository.EnrichItem`), + and persist the shortcut list (Task 4). The icon source is CONFIRMED to be `CreateObject` for + contained pack items (ACE `WorldObject_Networking.cs:79` writes IconId unconditionally). +- **Step 0 verification:** confirm against **ACE source** (`WorldObject.SerializeCreateObject` + / the weenie property serialization) that a *contained* pack item's `CreateObject` actually + carries `IconId` (synthesis risk #3 — LIKELY, not yet byte-traced). Reading ACE is sufficient; + no live capture needed. If ACE only sends `IconId` for world-visible objects and relies on + `PlayerDescription` for pack items, fall back to the PD inventory block as the icon source — + this is a branch the plan must resolve before the icon pipeline is wired. + +### 4.5 `ToolbarController` (new) — the `gmToolbarUI::PostInit` analogue + +- **Location:** `src/AcDream.App/UI/ToolbarController.cs` (alongside `VitalsController`, + `ChatWindowController`). +- **Bind:** `Bind(LayoutDesc 0x21000016, …)` — find the 18 slot `UiItemList`s by id + (`0x100001A7-AF` + `0x100006B7-BF`) into an ordered `_slots[18]`. Force the 2 meters + (`0x100001A1`/`A2`) + slider (`0x100001A4`) hidden (matches `gmToolbarUI::PostInit`). +- **Populate (port `UpdateFromPlayerDesc`):** on the `PlayerDescription` arriving, `Flush` all + slots, then for each `Parsed.Shortcuts` entry resolve `ObjectGuid` → `ItemRepository` item → + set `_slots[Index]`'s cell `ItemId`. The cell renders the composited icon from the item's + `IconId`. +- **Deferred re-bind (port `SetDelayedShortcutNum`):** if a shortcut's guid is not yet in + `ItemRepository`, record it pending; when `ItemRepository` raises item-added for that guid, + bind the waiting slot. (Reuse `ItemRepository`'s existing item-change events.) +- **Click-to-use (port `UseShortcut`):** a slot click → controller → existing + `InteractRequests.BuildUse` (`0x0036`) for the cell's `ItemId`, gated by the 0.2s + use-throttle (`ItemHolder::UseObject`). No special shortcut wire. +- **Depends on:** `PlayerDescriptionParser.Parsed.Shortcuts`, `ItemRepository`, the slot + widgets, the command/interact send path. + +### 4.6 Wiring & gating + +- The toolbar window is built by `LayoutImporter` from `0x21000016` and mounted in `UiRoot` + under `ACDREAM_RETAIL_UI=1`, like vitals/chat. Always-on this phase. Root is `Anchors=None` + + `Draggable` (whole-window-drag, IA-12 approximation) — NOT `Resizable` (faithful resize is + the deferred window manager). +- `GameWindow` wiring follows the existing vitals/chat drain pattern (one controller + constructed + bound; per-panel try/catch fault isolation already exists). + +## 5. Data flow (login → visible toolbar) + +1. Login → `PlayerDescription` arrives → `PlayerDescriptionParser` fills `Parsed.Shortcuts`. +2. In parallel, the player's pack items arrive as `CreateObject` messages → `ItemRepository` + stores `ItemInstance`s **including `IconId`** (the §4.4 extension). +3. `ToolbarController` (bound to the imported `0x21000016` window) runs its populate pass: + for each shortcut, resolve guid → item → set slot `ItemId`. Missing items → pending, + re-bound on item-added. +4. Each filled `UiItemSlot` asks `IconComposer` for the composited 32×32 texture (cached by + icon-id tuple) and draws it; empty slots draw `0x060074CF`. +5. Click a filled slot → use-item (`0x0036`) with throttle. + +## 6. Testing strategy + +Conformance tests in the layer matching each unit; dat-free fixtures where possible (mirror +the vitals `0x2100006C` golden-fixture approach). + +- **`CreateObject` IconId** (`tests/AcDream.Core.Net.Tests`): a golden `CreateObject` byte + buffer parses with the expected `IconId` (and the previously-discarded fields). +- **`IconComposer`** (`tests/AcDream.App.Tests`): layer ORDER + presence given a synthetic + icon-id tuple (assert the composite requests layers bottom→top in the `RenderIcons` order; + assert the cache returns the same texture for the same tuple). The `ReplaceColor` tint math + gets a small unit test against a known palette index. +- **`UiItemSlot`** (`tests/AcDream.App.Tests`): `ItemId==0` selects the empty sprite; + `ItemId!=0` requests the composite. `ConsumesDatChildren==true`. +- **`UiItemList`**: `AddItem`/`Flush`/`GetNumUIItems`/`GetItem` over single-cell instances. +- **`ToolbarController`**: find-by-id binds 18 slots from a fixture tree; shortcut→item + resolution sets the right slot; an item arriving late triggers the deferred re-bind; a slot + click emits a use-item for the bound guid with the throttle respected. Meters/slider hidden. +- **Build + full suite green** before the visual gate. + +## 7. Acceptance criteria + +- `dotnet build` + `dotnet test` green. +- **Visual (the user's gate):** launch, log in `+Acdream` → an 18-slot action bar renders with + the correct dat chrome + empty-slot sprites; any persisted shortcuts show their **real + composited item icons**; clicking a pinned item **uses** it (observable server-side / + in-world).

The chat window +must stay visually and behaviorally identical through every step except the final +(gated) vitals rewire. + +### 1.1 Why this is mostly already done + +The trace that opened this work (re-confirmed in this design session) established +two facts that make the generalization a *registration* task, not a new mechanism: + +1. **The importer's base-chain Type resolution is already retail-faithful.** + `ElementReader.Merge` resolves a Type-0 placement element up its + `BaseElement`/`BaseLayoutId` chain to the base's real registered Type + (`ElementReader.cs:137-140`). Every chat/vitals element therefore already + resolves to the retail class it would instantiate. + +2. **Type 12 is `UIElement_Text` — a real behavioral class, not a "style + prototype to skip."** Verified directly in the decomp: + `UIElement::RegisterElementClass(0xc, UIElement_Text::Create)` + (`docs/research/named-retail/acclient_2013_pseudo_c.txt:115655`). The + `Type==12 → return null` rule in `DatWidgetFactory` is a *vitals-only Plan-1 + expedient* (AP-37: skip the vitals number elements so they render via + `UiMeter.Label`), **not** a structural truth. + +So the "wrinkle" feared in the start-cold note (Type-0/12 elements hiding their +real widget type) **dissolves**: the resolved Type is already correct. The factory +just needs to *register* generic widgets for those Types instead of skipping them +or dropping to `UiDatElement`. + +### 1.2 Why this matters beyond chat (the strategic purpose) + +Chat is the **proving ground**, not the destination. The payoff is that every +future panel — **inventory, spell bar, vendor, character sheet, trade, skills** — +becomes *assembled from dat data + a thin controller* instead of being hand-built +from scratch. That is exactly how retail did it (`gm*UI::PostInit` everywhere on a +shared `UIElement` toolkit), and it is the reason to do this pass carefully now. + +**What this pass gives all future windows (the foundation):** +- The **generic widget toolkit** — `UiButton`, `UiField`, `UiScrollbar`, `UiText`, + `UiMenu` — built automatically by `DatWidgetFactory` from the dat layout. +- The **thin-controller pattern** — find-widget-by-id → bind-live-data — proven and + cemented on chat. Inventory's controller, vendor's controller, etc. all take the + same shape. + +**What those specific windows additionally need (out of scope here; cheap once the +pattern exists):** +- **A few more widget Types** — inventory/vendor lists want `UiListBox` (Type 5) + and `UiPanel` (Type 8); item slots want **drag-drop**, which retail builds into + `UIElement_Field` (the decomp shows `Field` has `CatchDroppedItem` / + `MouseOverTop` drag-drop hooks — so drag-drop rides on the Field widget this pass + already builds). Each gets *registered when that window needs it* — which is + exactly why §3 bounds "full registry" to the Types chat+vitals use today rather + than speculatively building all 14 retail classes. +- **The window manager** — open/close/z-order/persist, drag-bars (Type 2), + resize-grips (Type 9). This is the *other* half of Plan 2 — a sibling piece to + this one — and lands alongside, because pop-up/stackable windows (inventory, + vendor) need it. +- **Per-domain data plumbing** — item icons, live container contents, vendor stock + lists. Game-state work, separate from the UI toolkit. + +This pass is therefore the **reusable toolkit + assembly pattern** that makes those +later windows mostly-free to build. It is the load-bearing first half of the road +to inventory/vendor/spell-bar, not the whole road. + +--- + +## 2. Retail reference (the registry + the PostInit pattern) + +### 2.1 The Type → class registry (`UIElement::RegisterElementClass`) + +Confirmed verbatim from `acclient_2013_pseudo_c.txt` (line numbers cited): + +| Type | Retail class | Reg. line | | Type | Retail class | Reg. line | +|---|---|---|---|---|---|---| +| 1 | `UIElement_Button` | :125828 | | 9 | `UIElement_Resizebar` | :118938 | +| 2 | `UIElement_Dragbar` | :119926 | | 0xb (11) | `UIElement_Scrollbar` | :124137 | +| 3 | `UIElement_Field` (editable) | :126190 | | 0xc (12) | `UIElement_Text` | :115655 | +| 5 | `UIElement_ListBox` | :121788 | | 0xd (13) | `UIElement_Viewport` | :119126 | +| 6 | `UIElement_Menu` | :120163 | | 0xe (14) | `UIElement_Browser` | :118718 | +| 7 | `UIElement_Meter` | :123316 | | 0x10/0x11 | `ColorPicker`/`GroupBox` | :118396/:118177 | +| 8 | `UIElement_Panel` | :119820 | | — | **Type 0 and 4: NOT registered** | — | + +Type 0 has no class of its own — a Type-0 element is a placement/override that +inherits its class from its base. That is exactly what `ElementReader.Merge` +already does. + +> **Implementation correction (2026-06-16, settled during execution).** Two of +> this design's registration assumptions changed once the empirical resolved +> Types were in hand (Task 1): +> 1. **The editable input `0x10000016` resolves to Type 12 (Text), not Type 3.** +> So the input is **Variant B** — the factory builds it as a `UiText` +> placeholder and `ChatWindowController` removes that and controller-places a +> `UiField` at its rect.

Approved scope + +**Decision (this session):** *Full registry, chat-first, vitals rewire as the +final, separately-committed, separately-gated step.* + +**In scope:** +- Register generic widgets for the Types the chat + vitals windows actually use: + **Button (1), Field (3), Menu (6), Scrollbar (11), Text (12)** — plus Meter (7) + already done. +- Delete the `Type==12 → return null` skip; Type 12 becomes `UiText`. +- Collapse `ChatWindowController.Bind` to a find-by-id binder (no widget + construction). +- **Final gated step:** rewire `VitalsController` to bind generic `UiText` for the + vitals numbers (retail-faithful: vitals numbers *are* `UIElement_Text`), + retiring `UiMeter.Label` for vitals. + +**Explicitly NOT in scope ("full registry" is bounded to what these windows use):** +- The long tail retail also registers — `Panel` (8), `Dragbar` (2), `Resizebar` + (9), `ListBox` (5), `Viewport` (13), `Browser` (14), `ColorPicker` (16), + `GroupBox` (17). Those elements **continue to render correctly as + `UiDatElement`** (the universal fallback is non-negotiable). No + `UIElement_ColorPicker` port for a window that has no color picker. When a future + window needs one of these, it gets registered then. +- No new chat *features* (tabs/squelch/name-tags/word-wrap remain as the chat + re-drive deferred them — see that spec's §2). +- `UiMeter.Label` is **not deleted** — it stays for plugin/markup panels; vitals + simply stops using it. + +--- + +## 4. Design + +### 4.1 `DatWidgetFactory` — the faithful Type switch + +`DatWidgetFactory.Create` grows from `{7 → UiMeter, _ → UiDatElement}` to: + +```csharp +UiElement e = info.Type switch +{ + 1 => BuildButton(info, resolve, datFont), // UIElement_Button + 3 => BuildField(info, resolve, datFont), // UIElement_Field (see §4.3a) + 6 => BuildMenu(info, resolve, datFont), // UIElement_Menu + 7 => BuildMeter(info, resolve, datFont), // UIElement_Meter (unchanged) + 11 => BuildScrollbar(info, resolve), // UIElement_Scrollbar + 12 => BuildText(info, resolve, datFont), // UIElement_Text + _ => new UiDatElement(info, resolve), // generic fallback (unchanged) +}; +``` + +The rect/anchor/z-order propagation at the bottom of `Create` is unchanged. The +`Type==12 && StateMedia.Count==0` skip is **removed** — but a *pure base +prototype* (Type 12 with no own geometry that is only referenced via +`BaseLayoutId`, never placed) must still not draw. In practice such prototypes are +never top-level placed elements in `0x21000006`/`0x2100006C`; the importer only +builds placed elements. **Plan-phase verification #2:** confirm no Type-12 +prototype is double-built after the skip is removed (the chat/vitals golden +fixtures catch this). + +Each `BuildX` extracts the widget's dat-derived data (sprite ids per state, label +font) the same way `BuildMeter` extracts its 3-slice grandchild sprites. The +controller binds providers/callbacks afterward. + +### 4.2 The generic widgets + +Each generic widget extends `UiElement`, is constructed by the factory from +`ElementInfo`, and exposes **data providers + callbacks** for the controller to +bind. The chat-specific knowledge moves *out* of the widgets and *into* the +controller (faithful: retail's `gmMainChatUI`, not `UIElement_Menu`, owns the +talk-focus channel list). + +| Generic widget | Type | Derived from | Generic surface (dat-built + provider-bound) | Controller binds | +|---|---|---|---|---| +| `UiScrollbar` | 11 | `UiChatScrollbar` (already 100% generic) | track/thumb/cap/arrow sprite ids from dat; `Model : UiScrollable` | `Model = transcript.Scroll` | +| `UiButton` | 1 | `UiDatElement`+`OnClick` | state sprites (Normal/Pressed/Disabled), `Label`, `LabelFont`, `LabelColor`, `OnClick`, `NaturalWidth()` autosize | `OnClick`, caption | +| `UiMenu` | 6 | `UiChannelMenu` | popup toggle, 2-col layout, 8-piece bevel, row highlight; `Items : IReadOnlyList<(string label, bool enabled, object payload)>`, `OnSelect : Action`, `Selected`, `NaturalButtonWidth()` | populate 14 channel `Items`; map payload↔`ChatChannelKind`; `AvailabilityProvider` | +| `UiText` | 12 | `UiChatView` | scrollable + selectable multi-color line list, clipboard, dat-font; `LinesProvider : Func>`; shares `UiScrollable` (`Scroll`) | `LinesProvider` → ChatVM + per-kind colors | +| `UiField` | 3 | `UiChatInput` | editable one-line: caret/selection/clipboard/history/auto-repeat/focus-sprite-swap; `Text`, `OnSubmit`, `MaxCharacters` | `OnSubmit` → `ChatCommandRouter` | + +**Placement.** The generic widgets live in `src/AcDream.App/UI/` alongside +`UiMeter` (toolkit widgets). The factory in `src/AcDream.App/UI/Layout/` +references them. This matches the current split (`UiMeter` in `UI/`, +`UiDatElement` in `UI/Layout/`). + +**Naming.** `UiX` mirrors retail `UIElement_X`. The old chat-prefixed names are +removed (or kept as thin obsolete aliases only if needed mid-migration). + +### 4.3 The two wrinkles + +**(a) The editable input (Type 12 vs Type 3).** Robust to either resolution: +- If `0x10000016` resolves to **Type 3** → factory builds `UiField` directly; the + controller only binds `OnSubmit`. +- If it resolves to **Type 12** → the dat element is a display Text in this + layout; the controller *replaces* it with a controller-placed `UiField` at its + rect (today's pattern for the track/menu). `UiField` exists as a registered + generic widget regardless; only *who places it* differs. + +Editing behavior (caret/clipboard/history) is never purely dat-derivable, so the +input is always provider-bound — the open question only affects whether the +factory or the controller *instantiates* it. + +**(b) Vitals rewire — the final gated step.** Removing the Type-12 skip means the +vitals number elements (Type-0 → base Type-12 Text) *could* build as real +`UiText`. Today they are **meter children, consumed** (the importer does not +recurse a meter's children — `LayoutImporter.cs:113`), rendered via +`UiMeter.Label`. The faithful move: `VitalsController` constructs/binds a `UiText` +for each number (matching retail `UIElement_Text` vitals numbers) and drops +`UiMeter.Label` for vitals. + +This is **step 7 — the last commit, separately gated**, with its own fixture +update and the user's visual sign-off, because vitals shipped pixel-identical and +is fixture-locked (`vitals_2100006C.json`). If the rewire risks the pixel-identical +result, we **stop and keep the meter-label path** for vitals — a smaller, +documented divergence (AP-37 narrowed, not retired). The decision to land step 7 +is the user's, made on the running client. + +### 4.4 The thin controller (after step 6) + +`ChatWindowController.Bind` collapses to: for each known element id, `FindElement(id) +as UiX`, null-check, bind data/callback. The reflow/maximize/resize-bar-drop logic +(`ChatWindowController.cs:155-297`) stays — it is window-layout policy, not widget +construction. The `BuildLines` / `WrapText` / `RetailChatColor` helpers stay (chat +data shaping). What *leaves* the controller: the construction of `UiChatView`, +`UiChatInput`, `UiChatScrollbar`, `UiChannelMenu` (now factory-built) — the +controller binds them instead. + +--- + +## 5. Migration sequence (one widget per commit; build + test green each step) + +Ordered least-risk → most-risk; the chat window is fully generalized before vitals +is touched. Each step: `dotnet build` green, `dotnet test` (AcDream.App.Tests) +green, its own commit naming the widget; the live chat window stays visually +identical through steps 1–6. + +1. **`UiScrollbar`** (Type 11) — promote `UiChatScrollbar` (already generic); + register; factory builds it; controller binds `Model`. +2. **`UiButton`** (Type 1) — extract from `UiDatElement`+`OnClick`; register; Send + + Max/Min build from the dat. +3. **`UiMenu`** (Type 6) — generalize `UiChannelMenu`; register; controller + populates channel `Items` + maps payload↔`ChatChannelKind`. +4. **`UiText`** (Type 12) — generalize `UiChatView`; register; **delete the Type-12 + skip**; controller binds transcript lines. Guard: verify vitals still renders + (its numbers are meter-consumed → no auto-double-draw) via the vitals fixture + + a live launch. +5. **`UiField`** (Type 3) — generalize `UiChatInput`; register; wire the input per + §4.3(a) (verification #1 resolves factory-built vs controller-placed). +6. **Thin the controller** — collapse `ChatWindowController.Bind` to pure + find-by-id binding now that the factory builds everything. +7. **Vitals rewire (gated)** — `VitalsController` binds `UiText` numbers; fixture + update + the user's visual sign-off. **Stop-and-confirm gate.** + +--- + +## 6. Testing & conformance + +- **Generic-widget unit tests** (pure, no GL/dat) — mostly *moved* from the + existing chat-widget tests, renamed to the generic widgets: caret↔pixel + history + (`UiField`), thumb ratio / page-delta (`UiScrollbar` via `UiScrollable`), menu + item-pick + availability (`UiMenu`), line wrap / selection / dat-font hit-test + (`UiText`). +- **Factory tests** — `DatWidgetFactoryTests` grows one assert per newly registered + Type → correct widget class. +- **New chat-layout golden fixture** `tests/AcDream.App.Tests/UI/Layout/fixtures/chat_21000006.json` + (peer of `vitals_2100006C.json`): the resolved chat tree — each element's id, + rect, resolved Type, sprite ids — asserting the factory builds the right widget + per element. This locks the generalization. +- **Vitals fixture `vitals_2100006C.json` stays green, untouched, through steps + 1–6**; updated only at step 7, with visual sign-off. +- **Visual acceptance** — the user launches `ACDREAM_RETAIL_UI=1` and confirms the + chat window is unchanged through steps 1–6, and the vitals window is unchanged + after step 7. + +--- + +## 7. Divergence-register impact + +- **AP-37** (`DatWidgetFactory.cs`/`LayoutImporter.cs`: Type-0 text skipped + meter- + collapse + vitals numbers via `UiMeter.Label`): **amended as steps land** — the + "standalone Type-0 text elements are skipped / a dedicated dat-text widget is + Plan 2" clause is retired when `UiText` ships (step 4); the vitals-numbers-via- + `UiMeter.Label` clause is retired at step 7, or **narrowed** (not retired) if + step 7 is deferred.

Write the 8-int + set per instance into a new buffer parallel to `_gpuInstanceTransforms` (same shape + as `_clipSlotData`); bind at binding 5. On a no-lights frame, fill -1 (shader adds no + point light) and still bind a ≥1-element buffer so the SSBO is never unbound. +4. **Cell centre/radius:** world-space bounding sphere of the cell geometry — reuse the + cell's existing visibility bound (the BSP/AABB sphere already computed for culling). + The exact field is pinned during planning by reading the cell-storage structs in + `EnvCellRenderer` / `EnvCellLandblock`; fallback = centre from the cell-part transform + translation, radius from the cell vertex AABB. **This is the one detail to confirm + against code in the plan.** + +Order independence: D-1 and D-2 are orthogonal (shader math vs buffer binding) and can +be implemented in either order, but ship together. + +## Testing (TDD) + +`LightBake.cs` already encodes the correct math: `PointContribution` = per-light capped +(matches `mesh_modern.vert` pointContribution line-for-line), `ComputeVertexColor` = sum +reaching point lights → clamp `[0,1]`, skip directional.

The Coldeve blank-icon bug is fixed at the root, and the +foundation D.5.5's panels sit on is in place. + +This is a **data-model + ingestion** phase. No new panels ship; the toolbar (D.5.1) is the +only live consumer and must keep working (visually unchanged). + +## 2. The crux — settled (the three brainstorm decisions) + +The handoff's §2 framing ("retail unifies everything under one `ClientObjMaintSystem`") was a +misread. The named decomp shows retail is a **two-table** design, and the brainstorm settled +the architecture against that ground truth: + +1. **Two tables, fix ingestion** (not unify). Retail's `CObjectMaint` holds *two* hash tables + keyed by the same guid — `object_table` (`CPhysicsObj`, render/physics) and + `weenie_object_table` (`ACCWeenieObject`, data/UI) — cross-linked by pointer, created and + destroyed together. The UI *only* calls `GetWeenieObject(guid)`; physics *only* calls + `GetPhysicsObject(guid)`. acdream's existing `WorldEntity` + item-table split already + mirrors this. We keep them separate (joined by guid) and fix the *ingestion*, not the + structure. A merge would also violate Code Structure Rule 2 (`WorldEntity` carries + `MeshRef`/GfxObj dat handles and rendering-coupled AABB math; merging drags GL into + `AcDream.Core`). + +2. **Complete model + container index.** Capture the full item weenie-field set (currently + parsed-then-discarded) into the data object, maintain a live container-membership index + (`containerGuid → ordered items`), evict on `DeleteObject`, fix the `WeenieClassId` misuse, + and expose a formal resolve-by-guid surface. Defer only the panel UIs and panel-driven + flows to D.5.5. + +3. **All objects (true weenie table).** `CreateObject` upserts *every* object (creatures, + players, NPCs, items) into the data table, making it acdream's `ACCWeenieObject`-equivalent + and retiring the redundant `GameWindow._liveEntityInfoByGuid` (Name+ItemType duplicate) so + selection/target also resolves from the one table.

Per-object data record. *Change:* add the §6.1 fields; make `WeenieClassId` + settable; keep `PropertyBundle`. Item-specific fields are simply unset for creatures + (faithful to retail's `ACCWeenieObject` for non-items). + +2. **`ClientObjectTable`** (`AcDream.Core/Items/ItemRepository.cs` → renamed). The guid-keyed + store + container index + event surface. *Change:* + - `AddOrUpdate` becomes a **field-level merge upsert** (§7.2), not a whole-object replace. + - Add the container index: `Dictionary>` keyed by containerGuid, kept + ordered by slot; updated on upsert / `MoveItem` / `Remove`; exposed via + `IReadOnlyList GetContents(uint containerGuid)`. + - Events renamed `ObjectAdded/ObjectUpdated/ObjectRemoved/ObjectMoved`. + - `EnrichItem` deleted. + - Keep `ConcurrentDictionary` (plugin reads) + `GetItem`→`Get` resolve surface. + +3. **`ObjectTableWiring`** (new, `AcDream.Core.Net/ObjectTableWiring.cs`). Static + `Wire(WorldSession session, ClientObjectTable table)` subscribing the WorldSession + GameMessage-level events: `EntitySpawned`→`AddOrUpdate(merge)`, `EntityDeleted`→`Remove`, + `ObjectIntPropertyUpdated`→`UpdateIntProperty`. This is the seam that moves item ingestion + off `GameWindow` (Rule 1) while keeping `AcDream.Core` GL-free (Rule 2). + +4. **`CreateObject.cs`** (`AcDream.Core.Net/Messages`). *Change:* capture the §6.1 fields into + `Parsed` (extend the record); the wire-cursor walk already exists — replace the `pos += N` + skips with value reads. **Risk:** the `Parsed` positional ctor + `WorldSession.EntitySpawn` + mirror must both grow; cursor arithmetic must stay byte-identical (locked by tests). + +5. **`WorldSession.EntitySpawn`** (`AcDream.Core.Net/WorldSession.cs:47`). *Change:* add the + new fields so they reach the ingestion wiring. + +6. **`GameEventWiring.cs`** (`AcDream.Core.Net`). *Change:* `PlayerDescription` handler stops + creating "source of truth" stubs with `WeenieClassId = ContainerType`; instead it records + membership (a merge upsert that sets container/equip placement + marks the guid as the + player's). `WieldObject`/`InventoryPutObjInContainer` → `MoveItem` stays (already wired). + +7. **`GameWindow.cs`** (`AcDream.App`). *Change:* delete the `EnrichItem` call; construct + `ClientObjectTable` + call `ObjectTableWiring.Wire`; retire `_liveEntityInfoByGuid` and + point its consumers at `ClientObjectTable.Get`. Render-entity build is unchanged. + +8. **`ToolbarController.cs`** (`AcDream.App/UI/Layout`). *Change:* resolve via + `ClientObjectTable.Get`; event handler filters by guid (only re-bind affected shortcut + slots); subscribe to `ObjectRemoved` too (today it doesn't, leaving stale slots). + +9. **`IconComposer.cs`** — unchanged (takes fields, not the table). + +## 6. Data model + +### 6.1 `ClientObject` fields to add (capture from `CreateObject`) + +The `ClientObject` type **already declares** most of these fields (they exist on today's +`ItemInstance`), but `CreateObject` **does not populate them** — it walks past them on the +wire. This table is the wire-capture work: rows marked **new** also need a field added to the +type; the rest just need the parser to read the value into the existing field instead of +skipping it. The cursor walk already exists in `CreateObject.cs:558-806` (each field has a +`pos += N` skip today).

It is derived data, +rebuilt from each object's `ContainerId`/`ContainerSlot`: +- **on upsert:** if the object has a non-zero `ContainerId`, (re)index it under that parent. +- **on `MoveItem`:** remove from old container list, add to new (or to equip if `WielderId`). +- **on `Remove`:** drop from its container list. +- **expose** `GetContents(containerGuid)` → ordered item guids (inventory panel reads this). + +Equip placement (`WielderId` + `CurrentWieldedLocation`) is tracked the same way so paperdoll +can ask "what's equipped in slot X" without scanning. + +## 7. Ingestion lifecycle + +### 7.1 The flow +- **`CreateObject (0xF745)`** → `WorldSession` parses (full field set) → fires `EntitySpawned` + → **`ObjectTableWiring`** calls `ClientObjectTable.AddOrUpdate(merge)` for **every** object, + independent of whether it also becomes a `WorldEntity` (inventory items have no position). + `GameWindow` keeps its own `EntitySpawned` subscription for the render-entity build. +- **`DeleteObject (0xF747)` / Pickup** → `EntityDeleted` → `ClientObjectTable.Remove(guid)` + (today this leaks until `Clear()`). Render teardown unchanged. +- **`PlayerDescription (0x0013)`** → membership manifest: a merge upsert that marks each + inventory/equipped guid as the player's and records placement (container/equip slot). The + *data* (icon/name/type/…) arrives from `CreateObject`. Shortcuts stay on the existing path. +- **`WieldObject 0x0023` / `InventoryPutObjInContainer 0x0022`** → `MoveItem` (already wired) → + re-parents in the container index. +- **`PublicUpdatePropertyInt 0x02CE` (UiEffects)** → `UpdateIntProperty` (already wired, + preserved). + +### 7.2 Upsert = field-level merge (the key correctness rule) +`AddOrUpdate` must NOT replace the whole object (today's `_items[id] = item` clobbers appraise +`PropertyBundle` + move-state on a `CreateObject` re-send; retail's update branch patches via +`SetWeenieDesc`). The merge rule: +- **Absent** → insert the new object; fire `ObjectAdded`. +- **Present** → patch only the wire-carried fields onto the existing object (Name, Type, + Icon*, Effects, Stack, Value, Burden, capacities, `WeenieClassId`, and placement + `ContainerId`/`CurrentWieldedLocation`/`WielderId` when the wire carries them); **preserve** + the `PropertyBundle` (appraise detail) and any state the wire didn't carry; fire + `ObjectUpdated`. +- **Effects** keeps the D.5.2 contract: assign unconditionally from the parsed value (0 = "no + effect", a meaningful state) so re-composition reflects the current server state. + +### 7.3 Out-of-order safety +Because upsert is create-or-merge, the PD↔CreateObject arrival order is irrelevant: whichever +arrives first creates the entry; the other merges its fields in. No drops (the root fix for +the Coldeve bug), no silent races. + +### 7.4 Threading +Unchanged: the net channel drains on the render-thread `OnUpdate`; both tables mutate on the +render thread; `ConcurrentDictionary` is retained only for safe plugin reads. Events fire +synchronously on the render thread (matching today). + +## 8. Testing (conformance throughout) + +xUnit, hand-built byte fixtures (matching `CreateObjectTests` / `ItemRepositoryTests` style; +no pcap, no Moq). New + changed tests: +- **Full-field-capture parse:** each new weenie-header field reads correctly; cursor + arithmetic stays byte-identical (a packet with a mid-tail field set still reaches + IconOverlay/IconUnderlay). Extend `CreateObjectTests`. +- **Upsert creates a brand-new object** (no PD stub) — the Coldeve bug; this test would have + failed before the fix and locks it. +- **Upsert merge** preserves `PropertyBundle` (appraise) + move-state across a `CreateObject` + re-send; does not clobber. +- **Out-of-order:** CreateObject-before-PD and PD-before-CreateObject converge to identical + state. +- **Container index:** add/move/remove keeps `GetContents` correct and slot-ordered; 2-deep + container depth (r06 §7); equip placement queryable. +- **`DeleteObject` eviction** removes from the table + the container index. +- **`WeenieClassId`** is the real class id from CreateObject, not the PD ContainerType. +- **`_liveEntityInfoByGuid` retirement regression:** selection/describe still resolve + name+type for a creature via `ClientObjectTable.Get`. +- **Toolbar guid-filter:** an unrelated object's `ObjectAdded` does not re-bind a shortcut + slot; a shortcut's `ObjectUpdated` does. +- **Preserve** the D.5.2 effects tests (`effects==0` clears; per-pixel tint) under the new + merge path. + +## 9. Divergence register + +- **Retire** the enrich-only stopgap rows (the `EnrichItem` drops-unseeded-items behavior is + gone). Delete those rows in the same commit that lands the fix. +- **Add** a row for the global-event-with-guid-filter consumer model vs. retail's per-object + `NoticeRegistrar` observer dispatch (a deliberate simplification — consumers filter by guid + rather than registering per-object observers). Note it; don't hide it. +- **Add** a row (or note under it) for the deferred `null_object_table`-style parent/child + pre-queue (out-of-order *parented* create) — see §10. + +## 10. Risks & open questions + +- **Cursor arithmetic regression** in `CreateObject.cs` is the highest-risk change: turning + skips into reads must not shift any offset. Mitigation: the field walk already exists and is + test-covered; add per-field value assertions and a "mixed flags reach IconOverlay" test. +- **`AddOrUpdate` merge vs. replace** touches existing `AddOrUpdate` callers (PD seeding, + appraise `UpdateProperties`). Audit every caller; the merge must be a strict superset of + prior behavior for the toolbar path. +- **Event volume:** upserting all objects fires `ObjectAdded` per creature spawn. The toolbar + guid-filter handles it; future panels must filter too (documented in the table's event + XML-doc). +- **`_liveEntityInfoByGuid` retirement timing:** the ingestion wiring and `GameWindow`'s render + handler both subscribe to `EntitySpawned`; ensure the table is populated before any consumer + queries (consumers run on later user interaction, so this is safe, but assert it). +- **Parented item ordering** (a child `CreateObject` arriving before its parent) — retail uses + `null_object_table` pre-queuing. Deferred; PD↔CreateObject ordering is handled, but document + the parent/child gap so D.5.5 picks it up if a panel needs it. +- **Naming churn:** the rename touches `GameEventWiring`, `ToolbarController`, tests, and the + `IconComposer` call site. Mechanical but wide; do it as a focused rename commit so the diff + reads cleanly. + +## 11. Acceptance criteria + +- `dotnet build` + `dotnet test` green (the full suite, including the new conformance tests). +- A `CreateObject` for an item with **no** prior PD stub registers it in the table and the + toolbar renders its icon (the Coldeve repro, exercised by a unit test; visual confirmation + on a live server is the user's gate). +- The toolbar still renders correctly for pre-seeded items (no regression). +- Selection/target still resolves creature name+type after `_liveEntityInfoByGuid` retirement. +- Roadmap D.5 ledger updated (D.5.4 → shipped); divergence register rows added/retired; + memory digest updated if there's a durable lesson. diff --git a/docs/superpowers/specs/2026-06-20-d2b-drag-drop-spine-design.md b/docs/superpowers/specs/2026-06-20-d2b-drag-drop-spine-design.md new file mode 100644 index 00000000..56cb25d6 --- /dev/null +++ b/docs/superpowers/specs/2026-06-20-d2b-drag-drop-spine-design.md @@ -0,0 +1,367 @@ +# D.2b drag-drop spine (Stream B.1) — design + +**Date:** 2026-06-20 +**Phase:** D.2b retail-UI engine → D.5 core panels.

"Show / hide / raise +a top-level window" is the job it already does — so the registry lives there. + +This mirrors retail, where the Keystone root (`DAT_00870c2c`) owns the widget tree and window +stacking.

Components & interfaces + +### 4.1 `UiRoot` window registry + +A private `Dictionary _windows` plus: + +```csharp +/// Register a top-level window under a name for Show/Hide/Toggle. +/// Idempotent (re-register replaces). The dict is the source of truth — +/// independent of UiElement.Name, which is init-only and not reassigned here. +public void RegisterWindow(string name, UiElement window); + +/// Make the named window visible and raise it to the front. +/// No-op if unknown. Returns true if a window was shown. +public bool ShowWindow(string name); + +/// Hide the named window (Visible = false). No-op if unknown. +public bool HideWindow(string name); + +/// Flip the named window's visibility; Show (raise) if it was hidden, +/// Hide if it was visible. Returns the new IsVisible state. +public bool ToggleWindow(string name); + +/// Set element.ZOrder to one above the current max among top-level +/// children, so it paints + hit-tests above its peers. +public void BringToFront(UiElement window); +``` + +- `Show`/`Hide` only flip `UiElement.Visible`; `Visible` already gates Draw, Tick, and + HitTest (all early-return when false), so a hidden window is fully inert — no draw, no + input, no tooltip timer. +- `RegisterWindow` does **not** add the element to the tree — the caller mounts it with + `AddChild` (so registration and tree-membership stay independent and the caller controls + initial `Visible`). Registration only records the name→element mapping. +- `BringToFront`: `window.ZOrder = 1 + max(child.ZOrder for child in Children)`. The existing + default windows mount at `ZOrder = 0`, so an opened/clicked window rises above them. + +### 4.2 Raise-on-click + +In `UiRoot.OnMouseDown`, after the existing `FindWindow(target)` resolves the top-level +window under the press, call `BringToFront(window)` so the clicked window comes to the top of +the stack (retail raises clicked windows). This is the existing `FindWindow` result reused — +~3 lines, no new traversal. Applies to **any** top-level window (vitals, chat, toolbar, +inventory), not just registered ones; the registry is only for named Show/Hide/Toggle. + +### 4.3 `UiHost` forwarders + +```csharp +public void RegisterWindow(string name, UiElement window) => Root.RegisterWindow(name, window); +public bool ToggleWindow(string name) => Root.ToggleWindow(name); +``` + +### 4.4 F12 wiring — `OnInputAction` + +`InputAction.ToggleInventoryPanel` already exists, is already bound to **F12** in +`KeyBindings.RetailDefaults()` (matching `docs/research/named-retail/retail-default.keymap.txt` +line 149: `ToggleInventoryPanel [ "" [ 0 DIK_F12 ] ]`), and is already listed in the Settings +rebind UI — so it's user-rebindable with no new wiring. Today **nothing consumes it.** + +Add one arm to the `switch (action)` in `GameWindow.OnInputAction` (the `InputDispatcher.Fired` +multicast subscriber; the switch begins at GameWindow.cs:11421): + +```csharp +case AcDream.UI.Abstractions.Input.InputAction.ToggleInventoryPanel: + _uiHost?.ToggleWindow(WindowNames.Inventory); + break; +``` + +- Gating is already correct: the dispatcher is suppressed by `WantsKeyboard` when the chat + input holds focus, so F12 cannot toggle inventory while you're typing. +- `WindowNames.Inventory` is a `const string "inventory"` (a small `WindowNames` holder in + `AcDream.App.UI`), so the mount, the registry, and the toggle agree on one literal. + +### 4.5 Placeholder inventory window mount + +In the `_options.RetailUi` block of `GameWindow.OnLoad`, alongside the vitals/chat/toolbar +mounts, build a minimal framed window: + +```csharp +var inventoryWindow = new AcDream.App.UI.UiNineSlicePanel(ResolveChrome) +{ + Left = 200, Top = 120, Width = 320, Height = 400, + Visible = false, // starts hidden; F12 reveals it + Draggable = true, + Anchors = AcDream.App.UI.AnchorEdges.None, +}; +_uiHost.Root.AddChild(inventoryWindow); +_uiHost.RegisterWindow(AcDream.App.UI.WindowNames.Inventory, inventoryWindow); +``` + +This uses the same `UiNineSlicePanel(ResolveChrome)` + `RetailChromeSprites.Border` chrome +the vitals/chat windows use, so the placeholder already has the retail beveled frame. It is +**throwaway scaffolding**: Sub-phase B replaces the body (and likely the whole construction) +with the real `gmInventoryUI 0x21000023` nested layout, keeping the same registry name so the +F12 wiring is untouched. + +--- + +## 5. Persistence + +In-memory for the session only. Open/closed state lives in `UiElement.Visible`; window +positions are the hardcoded mount positions (already reset each session).

Its per-frame sun-zero for +sealed frames stays: it correctly models "a sealed dungeon runs only the interior +stage" and harmlessly guards transient null-cell frames; the new per-instance flag +adds the windowed/look-in coverage it was missing. The two together reproduce +retail's per-stage `useSunlight` for every case. **Do not touch the ambient values +or the sun colors here.** + +### 3.4 `EnvCellRenderer` — UNCHANGED + +Mode-1 draws set `uLightingMode = 1`, so the `instanceIndoor[]` read (inside the +uniform `uLightingMode == 0` branch) is never executed for EnvCell shells. The walls +already skip the sun and already get their torch set. No binding=6 bind needed. + +## 4.

Problem (verified root cause — condensed) + +A teleport to a FAR town places the player correctly, then the per-frame outdoor resolve **marches the +cell-id LABEL one landblock south per physics quantum (~33 ms)** while the **body barely moves**. It is a +cell-membership *label* cascade, NOT a free-fall. The `17410` ACE rejects is a wire-conversion artifact. + +**Single proximate trigger:** `CellTransit.cs:736` discards the `bool` from +`CellGraph.TryGetTerrainOrigin`. For an unstreamed neighbor that returns `(Vector3.Zero, false)`, and the +resolve uses `(0,0)` as the block origin ("legacy anchor-frame" fallback, self-documented at +`CellTransit.cs:732-735`). `GetOutsideLcoord` then does `floor(-0.088/24) = -1`, so the cell marches; the +correct origin `(0,-192)` would give `+7`. Far-town-only because the streaming center follows login/teleport, +so a fresh teleport lands at the *edge* of the streamed region where neighbors are unregistered. + +**The non-agnostic assumption:** acdream's physics position is a **streaming-relative world `Vector3`** +(`worldXY = (lb − _liveCenter)·192 + local`). The `(cell, local)` pair is *reconstructed* from a moving +reference (`_liveCenter`) every frame, so it can drift apart.

Whitelisting +EncumbranceVal+aug would be smaller but would re-introduce the same "value never arrives" class of +bug for the next property we need. No downside: the player object is the client's own authoritative +store. + +### 4.2 Loosen the int-apply gate to all ints (vs. extend the whitelist) +**Chosen: apply all ints.** Same reasoning. `UpdateIntProperty` already stores any int in the +bundle and only special-cases UiEffects for the typed mirror; the gate in `ObjectTableWiring` is the +sole thing dropping non-UiEffects ints.

It plays a **fade + portal-tunnel animation that COVERS the world-load wait**, holds +input and the camera, **waits until the world has actually loaded**, then places the player at a single exit +point. The same flow drives **login, logout, death, and portal** — it is the client's one "go somewhere" +primitive. Porting it faithfully fixes the float, the timing, the input-lock, **and** the #145 residual (the +hold removes the unstreamed-arrival gap entirely). + +acdream already has the *skeleton*: `PlayerState.PortalSpace` (input freeze) + `TeleportArrivalController` +(hold-until-ready) + `TeleportArrivalRules` (the readiness verdict).

The **visible result is identical to a fade to +black**, which is what acdream will reproduce (§3.3). + +### 2.3 The tunnel swirl + +During the four `TUNNEL*` states the world is hidden (`SmartBox::Hide`) and a **portal viewport is shown**: +a `UIElement_Viewport` (Type 0xD, child id `0x10000436`) hosting a `CPhysicsObj` made from +`GetDIDByEnum(0x10000001, 7)` (the portal setup object), with a distant light, camera at `(0.24, −2.7, 0.88)`, +playing animation `GetDIDByEnum(0x10000002, 7)` at **40 fps**, plus a **randomized camera-direction rotation** +each segment (`CreatureMode::SetCameraDirection_Degrees`, new random end-angle + duration via `RandDouble`). +The "In Portal Space - Please Wait..." string is (re)displayed each time the rotation segment restarts. +The `GetDIDByEnum` ids are runtime EnumIDMap lookups — the concrete dat ids must be resolved by a runtime +trace (§8, the swirl slice's prerequisite). + +### 2.4 The "world has loaded" signal (the hold gate) + +`SmartBox::teleport_in_progress` (pc 90815) `= (player != 0) && (position_update_complete == 0)`. +`TAS_TUNNEL` holds while this is true. `position_update_complete` is **cleared** on receipt of a server +teleport (`SmartBox::HandlePlayerTeleport`, 91200, sets `waiting_for_teleport = 1`); it is **set to 1** in +`SmartBox::UseTime` (94184) once `waiting_for_teleport == 0` — which clears when the player's physics state +settles (`DoSetState`, state bit `0x40` cleared). i.e. retail advances on **state-settled**, not a timer.

The sequencer owns the durations/transitions; + it knows nothing about *how* the fade or tunnel are drawn. `worldReady` is supplied by the controller (the + arrival hold). It emits `Place` when leaving `TUNNEL` (world loaded) and `FireLoginComplete` at `OFF`. + +- **`TeleportFlowController`** (`AcDream.App.World`). Owns one `TeleportAnimSequencer` + the existing + `TeleportArrivalController`. Each frame: ask the arrival controller whether the destination is ready, feed + that as `worldReady`, tick the sequencer, then apply the snapshot/events: drive the fade overlay alpha, + show/hide the tunnel viewport, play sounds, hold/clear the input lock, and on `Place` invoke the existing + placement (`PlaceTeleportArrival`), on `FireLoginComplete` send GameAction `0xA1`. It is the **single owner** + of "a teleport is happening"; the four entry points all call into it. + +- **`TeleportFadeOverlay`** (`AcDream.App.UI`) — a `UiRoot` child (last, top-most among retail-UI) that fills + the screen with `(0,0,0,FadeAlpha)` via `TextRenderer.DrawRect` inside the existing `UiHost.Draw` pass + (`GameWindow.cs:8885`). No new GL infra. + +- **`PortalTunnelView`** (`AcDream.App.Rendering`) — **net-new**: an offscreen 3D sub-scene rendering the + resolved swirl `CPhysicsObj` at 40 fps with the randomized camera spin, blitted to the screen during + `ShowTunnel`. This is the heaviest slice and is gated on the asset trace (§7, §8). + +Relationship to the existing controller: `TeleportArrivalController` stays the **pure hold** ("is the world +ready, and place when so"); `TeleportFlowController` is the **visual/timing/lock state machine** wrapped +around it. The arrival controller's "ready" verdict is the sequencer's `worldReady` gate (the +`teleport_in_progress` analogue). + +### 3.2 State machine + +Port §2.1 verbatim: states, the 1.0/2.0/5.0 s constants, the per-entry start states (§2.5). `FadeAlpha` is +`lerp` per §2.2 with `t = clamp(elapsed/FADE_TIME, 0, 1)` and a **smoothstep** ease in place of retail's +`GetAnimLevel` table (§8 — upgrade to the real table if a cdb read resolves it; *register row*). The +`TUNNEL → TUNNEL_CONTINUE` edge fires when `worldReady` first becomes true (retail's `EndTeleportAnimation`); +`MAX_CONTINUE_TIME` forces progress if it never does (the safety net, replacing the current 600-frame timeout +semantics). + +### 3.3 Visual cover + +- **Fade:** the `TeleportFadeOverlay` alpha-black quad (§3.1). *Register row: black-fade via alpha overlay, + not retail's near-plane collapse — visually identical, no camera-projection surgery.* +- **Tunnel swirl:** `PortalTunnelView` (§3.1) rendering the resolved swirl object. Prerequisite: a cdb trace + on a live retail teleport (bp `CPhysicsObj::makeObject`) to capture the concrete `GetDIDByEnum(0x10000001,7)` + / `(0x10000002,7)` dat ids (§8). During `ShowTunnel` the world is not drawn (sequencer drives this), matching + retail `SmartBox::Hide`. +- **"In Portal Space - Please Wait…"** text during `TUNNEL_CONTINUE` (`ShowPleaseWait`), drawn by the + retail-UI text layer. + +### 3.4 Readiness gate — Call-2 (folds in Work item A / #145 residual) + +Today `TeleportArrivalRules.Decide` returns `Ready` for **any outdoor** destination → immediate placement → +the NO-LANDBLOCK gap. The fix: + +- Add `PhysicsEngine.IsLandblockLoaded(uint landblockId) => _landblocks.ContainsKey(landblockId)`. Because + `AddLandblock` registers terrain + collision cells + portals **atomically** (`PhysicsEngine.cs:70`), + `ContainsKey` ⟹ the collision mesh is present and resolvable. +- `TeleportArrivalRules.Decide` gains an `outdoorLandblockReady` input; the outdoor branch returns `Ready` + **iff** the destination landblock is loaded, else `NotReady` (hold). Indoor still gates on + `IsSpawnCellReady` (unchanged). `Impossible` (un-hydratable claim) and the timeout safety-net are unchanged. +- **Why this is safe and self-resolving:** streaming **progresses during the hold** — `_streamingController.Tick` + runs unconditionally with the observer pinned to the destination (`GameWindow.cs:7420-7531`), and the #145 + `RemoveLandblock` of the stale source clears `CurrCell` so the dungeon-streaming gate ExitDungeonExpands to + the destination (`PhysicsEngine.cs:84-95`). The gate flips `Ready` the same frame `AddLandblock` fires + (`_teleportArrival.Tick` runs after the streaming drain — `GameWindow.cs:7551`). The player is therefore + **never** placed onto an empty world → no cell-march, no Z free-fall. The 10 s timeout remains a loud net. +- **Verified-by-apparatus first** (task #4): before relying on this, add a probe that logs the readiness verdict + transition + `_landblocks.Count` and confirms on a `0xC98C…`-style edge arrival that the gate flips `Ready` + *before* placement (pair with `ACDREAM_PROBE_RESOLVE` / `ACDREAM_CAPTURE_RESOLVE`). No guess-patch (the + original #145 burned 5 attempts). + +This is the single change that subsumes Work item A. After it lands, re-test the `launch5.log` scenario. + +### 3.5 Unification + de-dup + +The login auto-entry readiness (`GameWindow.cs:1036-1064`) and the teleport readiness +(`TeleportArrivalReadiness`, `:5419-5438`) are **verbatim duplicates** (the code comment says so). Extract a +single `ComputeArrivalReadiness(destPos, destCell)` used by both sites. The two `_liveCenter` recenters +(login `:2874-2882`, teleport `:5364-5371`) stay in their respective handlers but share one helper. This kills +the drift hazard where #135/#145-class bugs lived. + +### 3.6 Input / camera lock + +PortalSpace already freezes keyboard turns (the `Update` early-return precedes the yaw block). Two yaw leaks +remain (the handoff gotcha), both in the Silk mouse-move handler, bypassing the `Update` guard: +- **MMB mouse-look** (`GameWindow.cs:1098`) → `_mouseLook.ApplyDelta` writes `Yaw`. +- **RMB orbit** (`GameWindow.cs:1120`) → writes `_retailChaseCamera.YawOffset` / `_chaseCamera.YawOffset`. + +Fix: a `State == PortalSpace` early-return at the top of each branch. (No change to PortalSpace logic itself.) + +### 3.7 Sounds + +Resolve the EnterPortal / ExitPortal Wave ids from the dat SoundTable (§8) and play via +`OpenAlAudioEngine.PlayUiWave` (the UI-pool path; the `IAudioEngine.PlayUi(SoundId)` stub is a no-op — do not +use it).

The chosen design keeps the blast radius to the inventory, puts the logic in one testable helper, and reuses the proven `GameWindow`-reads-`0x21000037` + passes-to-`Bind` pattern. The importer route remains available for Sub-phase C if we later want all lists automatic. + +## 5. Divergence register impact + +- **No new deviation is introduced** — this *ports* the retail resolver for the inventory lists (a deviation retired, not added). +- The **hardcoded empty-slot art was never registered** (a pre-existing gap — a deviation without a row). This change makes it honest by adding **one narrow row**: *"The toolbar's item slots use the hardcoded `UiItemSlot.EmptySprite = 0x060074CF` rather than resolving their cell template via `0x1000000e`; correct in outcome (the toolbar's `0x1000000e` resolves to a generic prototype) but not dat-resolved. Retire when the toolbar is routed through `ItemListCellTemplate`."* (AP-55 or next free id, added in the implementation commit.) +- A second row for the **flat-cell approximation**: *"acdream's `UiItemSlot` is a flat single-sprite cell; for a prototype with both a frame child and an inner icon (the 36×36 backpack `0x1000033F`: frame `0x06005D9C` + inner `0x06000F6E`), only the dominant background (the frame) is drawn — retail clones the full prototype subtree.

Implementation outline + step-1 validation (this is how we "pin the exact asset") + +1. **Pin the values (first task).** Extend the layout dumper (`AcDream.Cli dump-vitals-layout`, the reflective ElementDesc walker) to surface each element's scalar **attribute/property table** (it currently prints geometry + states + media, omitting `Properties` keys like `0x1000000e`). Dump `0x1000000e` for `0x100001C6` (layout `0x21000021`), `0x100001C9` and `0x100001CA` (layout `0x21000022`). Record: the property type, the resolved prototype id, and that prototype's chosen sprite per §4.3. This **confirms the catalog is `0x21000037`** and **locks the golden test values**. (If `0x1000000e` is absent on a list element, escalate to the cdb fallback: break at `InternalCreateItem` `004e3616`, read arg4 + the catalog DID — per the research report's §"How to verify next".) +2. `ItemListCellTemplate.ResolveEmptySprite` + unit/real-dat tests. +3. `UiItemList.CellEmptySprite` + unit test. +4. `InventoryController.Bind` params + apply; update affected InventoryController tests. +5. `GameWindow` wiring. +6.

The bottleneck + is the render-thread **APPLY**, not the worker BUILD. `BuildLandblockForStreaming` + (`src/AcDream.App/Rendering/GameWindow.cs`, the `lock(_datLock)` at the build site) is fast and uncontended. + +2. **APPLY throughput — the "long transition."** A built landblock sits in the streamer outbox while the + render thread, saturated by the synchronous unbounded CreateObject flood (`WorldSession.Tick`, + `src/AcDream.Core.Net/WorldSession.cs:598-607`, drains the entire inbound queue per frame) and metered to + `MaxCompletionsPerFrame = 4` (`src/AcDream.App/Streaming/StreamingController.cs:90`, applied in + `DrainAndApply`), crawls through it. That is the 10–14 s the user feels. + +3. **Resolve-against-empty-world — the "dropped at the wrong position."** Outdoor teleports place + immediately on an unloaded world (`TeleportArrivalRules.Decide` returns `Ready` for outdoor; + `src/AcDream.App/World/TeleportArrivalController.cs:134-142`), so for the whole 10–14 s window the + per-frame swept-transition cell-march runs against nothing and emits a `result.CellId` with the + landblock-X byte **zeroed** (`0x00B40039` instead of `0xA9B40039`). The outbound encoder trusts that cell + id verbatim (the #107 fix, `src/AcDream.App/Rendering/GameWindow.cs:7794-7807`), so ACE receives a move + naming the wrong landblock and rejects **every** one (`MOVEMENT SPEED` → `failed transition` in the ACE + log). The player is desynced for the entire window. + +4. **`PortalSpace` input-freeze — the "stops at the portal" (separate).** `OnTeleportStarted` sets + `PlayerState.PortalSpace` (`GameWindow.cs:5582`); `PlayerMovementController.Update` early-returns a + zero-movement result (`src/AcDream.App/Input/PlayerMovementController.cs:862-876`), freezing both local + prediction and the outbound send. Independent of streaming. + +**What retail actually does (verified — ACE `Player_Location.cs:679-760`):** place the position immediately, +set `Hidden = true; IgnoreCollisions = true`, poll every 0.1 s until `CurrentLandblock.CreateWorldObjectsCompleted`, +then clear both. No input freeze, no position hold — collision/visibility are suppressed until the +destination is resident, then the player materializes. The retail *client* covers the same interval with the +portal-tunnel animation while physics keeps ticking. + +**Out of scope here (FPS):** the user observed 30–70 fps outdoors. This was a **Debug** build, which is not +representative. The general FPS question is deferred to its own measure-in-Release pass (see §6). + +--- + +## 2. Target experience (approved) + +A **retail tunnel cover**: starting a teleport plays a cover animation that hides the (now-short) load; the +player is "in transit" — not moving in the world — and pops out at the destination once it is resident. +Fidelity for this spec is a **fade cover** (fade-out → hold → fade-in), reusing the dormant +`TeleportAnimSequencer`. The authentic 3D portal-swirl is deferred to a later polish pass. + +This single model resolves all three teleport symptoms at once: +- The transit state means **no movement resolve runs against an empty world** → the cell frame cannot corrupt + (fixes the wrong-position desync). +- The fade **covers** the transit → the awkward freeze-in-place is gone (fixes "stops at the portal"). +- Materialization is gated on the destination being **resident**, which the foundation fix makes fast + (fixes the "long transition"). + +--- + +## 3. Architecture & new sequence + +Replaces "place-immediately + `PortalSpace` freeze." Phases: + +1. **TRANSIT-IN** — `OnTeleportStarted` (`0xF751`) drives `TeleportAnimSequencer` into fade-out → cover. + Input and outbound movement are suppressed *for the duration of transit*, but the fade covers it. + No movement resolve runs. +2. **AIM** — `OnLivePositionUpdated` (destination `UpdatePosition`) drops the stale source landblock, + recenters streaming on the destination, pre-collapses if the destination is a sealed dungeon, and begins + the arrival hold. The destination load is enqueued by the normal streaming `Tick` (unchanged; the probe + confirmed `ENQ` fires correctly during the hold). +3. **PRIORITY-APPLY** — when the destination landblock's completion lands in the streamer outbox, it is + applied immediately (out-of-band of the 4/frame budget), so the player's cell becomes resident in + ~hundreds of ms instead of 10–14 s. +4. **READY** — the arrival readiness flips when the player's **own** destination landblock terrain (+ the + EnvCell struct for an indoor destination) is resident. Outdoor changes from "place immediately" to + "hold-until-terrain-resident." +5. **MATERIALIZE** — `PlaceTeleportArrival` resolves against the now-resident destination (grounds + correctly; never takes the `NO-LANDBLOCK` verbatim branch), seeds the body's (cell, local) frame, + fades in, exits transit → `InWorld`, sends `LoginComplete`. + +### Components + +- **A — Priority-apply** *(`src/AcDream.App/Streaming/StreamingController.cs`, small/surgical)* + `StreamingController` gains a settable "priority landblock id" (the active teleport target). In + `DrainAndApply`, when a priority id is set, its completion is located and applied first/out-of-band so + the player materializes as soon as the worker finishes it (already ~170 ms). The id is cleared on + materialize. No change to the inbound network drain. Apply remains render-thread-only. + +- **B — Arrival controller** *(`src/AcDream.App/World/TeleportArrivalController.cs` + `TeleportArrivalRules`, + exist)* Outdoor readiness changes from unconditional `Ready` to **hold-until-terrain-resident**, using a + **correctly-keyed** residency check (the `EncodeLandblockId` 0xFFFF form — the bug fixed at `c880973` and + then reverted with Slice 2; do NOT reintroduce the `& 0xFFFF0000` raw-key mismatch). The controller drives + the TAS transit and materializes on `Ready`, or loud-fails on `Impossible`/timeout. The ~10 s frame-count + timeout is **retained as a loud safety net** (a real failure signal — worker crash / corrupt dat / OOB + coords) but should now rarely fire because residency is fast. + +- **C — Fade cover** *(`src/AcDream.Core/World/TeleportAnimSequencer.cs`, exists, 29 tests + a render overlay)* + Wire the dormant 7-state TAS to drive a full-screen fade overlay during transit, using its existing + `ComputeFadeAlpha`. The overlay is a render-layer addition (a screen-space quad whose alpha the TAS + drives). The authentic 3D swirl is explicitly NOT built here. + +- **D — Cell-march hardening** *(`src/AcDream.Core/Physics/` — the swept-transition cell-march)* + The swept-transition path must **preserve the body's landblock id** (never emit `lbX=0`) when the swept + position isn't covered by a resident landblock — return the body's seeded (last-known) cell rather than a + partially-derived one. `ResolveCellId` (`PhysicsEngine.cs:330-351`) already preserves its fallback; the + zeroing is in the swept `Transition`/`SpherePath` cell update, whose exact site is identified and fixed + during implementation. Defense-in-depth: with the transit model the player never moves against an empty + world on the normal path, but this also clips the #145 edge-arrival residual. + +--- + +## 4. Why this is not the reverted band-aid + +The reverted Slice-2 hold (`docs/research/2026-06-21-teleport-foundation-handoff.md`) was a band-aid because +(a) the foundation was slow, so it waited ~10 s, and (b) it force-placed on `NO-LANDBLOCK` after the timeout. +This design is different on both counts: + +- **(a) The foundation is fixed.** Priority-apply makes the player's destination resident in ~hundreds of ms + (the worker build is already ~170 ms; the only thing that was slow was the metered render-thread apply, + which we now bypass for the player's own landblock). +- **(b) Placement is on a real, grounded landblock.** Materialization resolves against a resident + destination — never the `NO-LANDBLOCK` verbatim branch — so the cell frame is correct and outbound + movement is accepted by ACE. + +The fade is the retail cover over a now-fast load, which is exactly what the handoff said is legitimate +"(and only then) a retail-style visual cover is polish, not a crutch." + +--- + +## 5. Error handling + +- **Destination never becomes resident** (worker crash / corrupt dat / OOB coords): the frame-count timeout + fires, force-materializes, and logs loudly (it is a genuine failure, not normal flow). With component D, + even a forced placement does not corrupt the outbound frame. +- **Impossible indoor claim** (cell id outside `LandBlockInfo.NumCells`): the existing + `IsSpawnClaimUnhydratable` → `ArrivalReadiness.Impossible` short-circuit is retained. +- **Re-sent server position mid-transit**: `BeginArrival` is server-authoritative and resets the hold + (existing behavior). + +--- + +## 6. Scope — what this spec does NOT do + +- **CreateObject-flood timeslicing (the deferred "#2").** Even after the player materializes onto correct + terrain, the town's *objects* (buildings, NPCs) keep flooding in synchronously, causing post-materialization + pop-in and an FPS sag for a few seconds. Bounding `WorldSession.Tick` per frame is a real improvement that + also helps general FPS, but it touches the inbound-drain path and is not strictly a *teleport* bug. Filed + as a follow-up; **measure in Release first.** +- **The authentic 3D portal-swirl** (fade cover ships now). +- **General outdoor FPS** (30–70 in Debug — re-measure in Release before treating it as a regression/leak; + the AP-48 unbounded-entity-map leak is a separate, already-registered concern). + +--- + +## 7. Testing & acceptance + +**Unit (per layer):** +- Priority-apply ordering — a priority id's completion is applied before the per-frame budget is spent + (`tests/AcDream.Core.Tests/Streaming/`). +- Outdoor + indoor readiness decision — outdoor now holds until terrain-resident; correctly-keyed lookup + (`tests/AcDream.App.Tests/World/` + `tests/AcDream.Core.Tests/`). +- Cell-march landblock preservation — a swept step whose position is over no resident landblock returns the + seeded cell (correct `lbX`), never `lbX=0` (`tests/AcDream.Core.Tests/Physics/`). +- The `TeleportAnimSequencer` keeps its 29 existing tests green. + +**Live acceptance (re-run the `tp-probe`):** +- The destination-LB `APPLY` lands within ~1–2 frames of its `BUILD` (was +10–14 s). +- The ACE log shows **no** `00B4…` / `MOVEMENT SPEED` / `failed transition` lines after a teleport. +- Visual: a covered (faded) transition that pops out onto real, grounded terrain — no run-in-place stutter, + no desync. +- The death→lifestone building keeps its collision (component A makes the dat-static building's landblock + resident before the player materializes; component D closes the cell-resolution residual). + +**Probe lifecycle:** the `tp-probe` (`PhysicsDiagnostics.ProbeTeleportEnabled` + the 5 log points) is the +acceptance apparatus. It stays until the fix is verified, then is removed (it is tagged `REMOVABLE`). If it +proves durably useful, promote it instead of removing — decide at verification time. + +--- + +## 8. Divergence register impact + +- **Retire** the "outdoor teleport places immediately because streaming doesn't progress during a hold" + divergence (the comment + behavior at `TeleportArrivalController.cs:134-142` / `GameWindow.cs:5519-5523`): + the premise was measured false (streaming DOES progress; only APPLY was slow).

RTT path + the `IUiViewportRenderer` seam (the crux) + +The 3-D doll renders into an off-screen buffer in the **pre-UI hook** (GameWindow, after the world +passes, before `_uiHost.Draw`); the `UiViewport` widget then blits the result during the 2-D UI pass. + +**Seam (layering decision — diverges from the handoff's "Core interface", with user approval):** +define `IUiViewportRenderer` in the **`AcDream.App.UI` namespace** (where `UiViewport` lives), +implemented by `PaperdollViewportRenderer` in `AcDream.App.Rendering`. `App.UI` is a namespace **within +the `AcDream.App` project**, not a separate project — so this is an **intra-App decoupling** (keep the UI +widget from depending directly on `WbDrawDispatcher`/`GameWindow`), not a cross-project seam. +Code-Structure Rule 2 keeps **Core** free of GL; Core has no consumer for "render an entity into a rect", +so a Core interface would over-apply the rule. Narrow surface: + +```csharp +// AcDream.App.UI +public interface IUiViewportRenderer +{ + // Renders the scene into an internal FBO sized (w,h); returns the GL color-texture handle. + // Called by the per-frame pre-UI hook, NOT from UiViewport.OnDraw. + uint Render(UiViewportScene scene, int width, int height); +} +``` + +`UiViewportScene` carries the doll entity ref + camera params (plain data; no GL). The pre-UI hook calls +`Render` and stores the returned handle on the widget; `UiViewport.OnDraw` blits that handle (§B). + +**`PaperdollViewportRenderer` (App rendering layer)** owns: +1. A `ManagedGLFramebuffer` sized to the widget rect, recreated when the rect changes. +2. The doll `DollCamera` (`ICamera`): eye `(0.12, −2.4, 0.88)`, look-at origin, perspective with the + rect's aspect. Decode/confirm the exact float→matrix mapping against `UIElement_Viewport::SetCamera`. +3. Per frame, gated on **inventory-open ∧ doll-view**: open a `GLStateScope`; bind the FBO; set viewport + to (w,h); clear color to transparent `(0,0,0,0)` + clear depth; write a **doll lighting UBO** (one + `DISTANT_LIGHT` = retail `(0.3,1.9,0.65)`@2.0, fixed ambient) reusing the scene-lighting UBO builder + (GameWindow ~8289); call `WbDrawDispatcher.Draw(DollCamera, [dollLandblockTuple], + animatedEntityIds:{dollGuid})`; dispose the scope (restores all GL state).

Approach (A1, recommended) — pre-read on the worker, drop the apply lock + +The streaming worker already holds `_datLock` for its build and already reads +many of these dats for rendering. Extend the worker's per-landblock output to +carry a **physics/registration dat bundle**: the parsed dat objects the apply +needs, read by the worker under the lock it already holds. The apply then +reads from the bundle instead of calling `_dats.Get`, makes zero +`DatCollection` calls, and its `lock(_datLock)` is deleted. + +Everything else in the apply stays exactly where it is and runs **on the +update thread, lock-free**: +- the terrain GL upload (`AddLandblockWithMesh`) — must stay on the GL thread; +- the CellSurface/PortalPlane **world-space build** (it needs the apply-time + `origin` = `_liveCenter`-relative; building it here keeps it in the correct + frame and sidesteps the trees-in-sky frame-mismatch class); +- all physics/registry mutation (`_physicsEngine.AddLandblock`, + `_physicsDataCache.CacheGfxObj`/`CacheBuilding`, `ShadowObjects.Register`, + `_envCellRenderer.FinalizeLandblock`). + +These touch only update-thread-owned structures; the worker never touches +them. Reading them from the bundle (instead of `Get`) changes *where the bytes +come from*, not *what is computed* — behavior is identical. This is a +threading change, not a behavior change; it is retail-neutral. + +## 5. Why dropping the lock is safe + +`_datLock`'s only cross-thread responsibility is serializing `DatCollection` +access (the streaming worker vs. the update thread). The apply's other +work — GL upload, physics engine, shadow registry, dat-data cache, +EnvCell renderer — is all update-thread-only; the worker (which only runs the +factory closures that read dats) never touches any of it. Therefore, once the +apply makes no `DatCollection` call, `_datLock` is unnecessary around it and +removing it introduces no new race. The live-spawn handlers +(`OnLiveEntitySpawnedLocked`) that also mutate the registry run on the **same** +update thread (via `_liveSessionController.Tick()` in `OnUpdate`), so they +never raced the apply regardless of the lock. + +**Required correctness check (implementation):** the bundled dat objects are +handed by reference from the worker to the update thread. This is safe iff +`DatCollection.Get` returns objects that are immutable after parse (read- +only DBObjs). The plan must verify this; if any returned object is mutated +post-parse, the bundle must carry a copy or the extracted primitive data +instead of the shared instance. + +## 6. Interface / data-flow changes + +- **`LandblockStreamResult.Loaded`** (and `Promoted`) gains a + `PhysicsDatBundle` payload (a small record holding: the `LandBlockInfo`, a + map of `EnvCell`+`Environment` by cell id, building `Setup`s by id, and the + entity `GfxObj`/`Setup`s by id needed for BSP + ShadowObjects). +- The worker's load closure (`BuildLandblockForStreamingLocked` → + `_loadLandblock`) populates the bundle under the lock it already holds, + reusing reads it already performs where possible. +- `ApplyLoadedTerrainLocked(lb, meshData, bundle)` reads every dat from + `bundle.X[id]` instead of `_dats.Get(id)`.

Decision recorded: the bottleneck is architectural, not language; a rewrite + discards ~200K lines of verified retail-faithful ports. +- No ECS in the simulation. `MovementManager`, the animation sequencer, physics + transitions, weenies keep their retail-mirroring OO structure — that correspondence + is the project's debugging methodology. +- No retail-visible behavior changes.

MP0 — Apparatus (honest measurement) + +New `FrameProfiler` (dedicated class in `src/AcDream.App/Diagnostics/`, NOT GameWindow; +CLAUDE.md structure rule 1): + +- **CPU frame time**: swap-to-swap delta, ring buffer, p50/p95/p99 + histogram. +- **GPU frame time**: whole-frame `GL_TIME_ELAPSED` query, **never enabled together + with any glFinish-style per-pass bracketing** (the 2026-06-23 lesson — separate + flags, enforced in code, not convention). +- **Per-stage attribution**: `glQueryCounter` (GL_TIMESTAMP) markers per pass — no + glFinish, no nesting conflict with the frame query. +- **Allocation counter**: `GC.GetAllocatedBytesForCurrentThread()` delta per frame on + the update thread + Gen0/1/2 collection counts. This is MP4's before/after meter. +- Toggles via `RuntimeOptions` + DebugPanel (structure rules 4/5); env + `ACDREAM_FRAME_PROF=1`. **Stays in the tree permanently** (unlike the throwaway + `ACDREAM_FPS_PROF`), because every MP gate reads it. + +**Gate:** a captured baseline report (dense-town steady + scripted traversal route) with +the CPU 6 ms attributed per stage. If the attribution contradicts §1's assumed split, +the MP phase order is re-sequenced and this doc amended before MP1 starts. + +**Gate PASSED 2026-07-05** — see `docs/research/2026-07-05-mp0-baseline.md`. +Verdict: render-side-CPU split CONFIRMED (GPU ≤ ~2.7 ms, stages ≈ 0); steady +medians better than assumed (worst town p50 3.6 ms; Fort Tethana axiom view +not yet re-measured — re-check at the MP2/MP3 gates). AMENDMENT: steady-state +allocation churn (1.5–3 MB/frame → gen2 GC ~1–2/s → all town p99/max +violations) is promoted to a first-class smoothness lever: after MP1, one +bounded allocation-triage session fixes top churn sites OUTSIDE the MP3 +rewrite surface; sites inside it wait for MP3; the full zero-alloc pass +remains MP4. Teleport hitch quantified: 211 ms worst frame, 75.7 MB +single-frame allocation — MP1's "before" number. + +## 6. MP1 — Bake + pak (the smoothness backbone) + +### 6.1 The bake tool + +`acdream-bake` — new project `src/AcDream.Bake/` (console; registered in +`AcDream.slnx`). Reads the user's dats via DRW + **the same interpretation code the +client uses today**, run offline: + +- Mesh extraction (GfxObj/Setup → GPU-layout vertex/index + batch tables) via the + existing ObjectMeshManager build path. +- Texture decode (palette/INDEX16/etc. → RGBA) via the existing TextureHelpers path. + **AMENDED 2026-07-05 (MP1a ground truth):** v1 pak stores **decoded RGBA8 exactly + as the runtime path produces today** (the atlas consumes RGBA8 via + `TextureBatchData` — storing BC7/BC1 would change delivered pixels and violate + this phase's byte-identical conformance gate). BC compression (quarter the disk + + VRAM, lossy) is an explicit post-conformance option requiring its own visual + gate and user approval, not v1 scope. Mip chains remain runtime-generated + (`GenerateMipmaps` flush) in v1 for the same reason. +- BSPs (physics, cell, drawing) flattened to index-based node arrays (blittable). +- Landblock terrain data (heights/attributes) as blittable arrays. +- EnvCells (geometry + portals + surfaces) as blittable records. +- Degrade tables (per-GfxObj slot `ideal_dist`/`max_dist`/ids) — MP2/MP3 read these. +- **Scenery placement**: `SceneryGenerator` evaluated per landblock at bake; the pak + stores final instance lists (deterministic function of dat data, so bake-safe). + +**Extraction prerequisite:** the CPU-side mesh/texture build code currently lives in +`AcDream.App` next to GL code. MP1 moves the GL-free parts into a new +`src/AcDream.Content/` assembly (no GL dependency) that both `AcDream.App` and +`AcDream.Bake` reference. This is a mechanical extraction (move + namespace), not a +rewrite — the same lines keep running. Inventory-doc update required (structure rule 2). + +### 6.2 Pak format (v1) + +Single file `acdream.pak` next to the dats (path via `RuntimeOptions`): + +- Header: magic `ACPK`, format version, **dat iteration stamps** (all four dats) + + bake-tool version. Stale/missing pak at launch → clear error naming the rebake + command (CLI era) → later: auto-offer (per §3). +- TOC: flat sorted array `(assetKey: u64 [type:u8 | fileId:u32 | variant:u24]) → + (offset: u64, length: u32, flags: u32)`; binary-search or hash lookup, O(1)-ish, + loaded once. +- Blobs 64-byte aligned, uncompressed in v1 (mmap + OS page cache + NVMe; LZ4 block + compression is a noted future option, not v1 scope). + +### 6.3 Runtime consumption + +- `PakReader` in **`AcDream.Content`** (AMENDED 2026-07-05: the spec originally said + Core, but MP1a established the dependency direction Content→Core, and the pak's + blob shapes are the `ObjectMeshData` family living in Content — a Core-resident + reader would be circular. Content is GL-free, so the layering intent is + preserved; Core stays untouched): one `MemoryMappedFile`, `GetBlob(key)` → + `ReadOnlySpan` into the view; typed access via `MemoryMarshal.Cast` over + blittable segments. **No locks anywhere** — immutable mapped memory is + thread-safe to read by construction. +- Streaming workers stop decoding: a landblock load becomes TOC lookups + handing + spans to the GL upload queue. The decode worker pool shrinks to the residual + runtime-decode set (below). Request-key dedup stays in the streaming layer + (cheap loads still shouldn't be duplicate loads). +- **Retires:** runtime DRW decode on the world *render/streaming* hot path; the + unbounded `DatDatabaseWrapper._cache`. The `PhysicsDatBundle` worker pre-read + **stays through MP1–MP3** (the physics apply consumes parsed DBObj types until MP4 + restructures physics data consumption) and is retired in MP4 when physics reads the + pak's flat arrays directly. + +### 6.4 What stays on runtime DRW (v1 scope control) + +| Stays runtime | Why | +|---|---| +| UI dat assets (sprites, fonts, LayoutDescs — D.2b) | low volume, cold path | +| Audio waves (`DatSoundCache`) | low volume, already cached | +| Character-appearance palette overlays (ObjDesc) | runtime-parameterized per entity; keeps existing decode + cache | +| Motion tables / animations (sequencer) | sim-side, small, load-once | + +`DatCollection` therefore stays in-process, off the hot path. Baking these later is a +listed follow-up, not v1. + +### 6.5 Conformance + gate + +- **Equivalence test:** load a fixture set (Holtburg blocks + a dungeon + a dense-town + block) through the legacy path and the pak path; diff meshes (vertex/index bytes), + textures (pre-compression pixels), BSP structures, scenery instance lists + field-by-field. Golden = legacy path. +- **Gate:** equivalence green; portal-hop / traversal p99 from MP0 shows the hitch + class gone; user visual gate (no missing/wrong geometry); legacy decode path deleted + from the streaming hot path in the gate commit. + +### 6.6 EnvCell dedup — REQUIRED (corrected 2026-07-05 after the full-bake gate) + +The runtime deduplicates interior-cell geometry under a **content hash** +(`EnvCellRenderer.GetEnvCellGeomId(environmentId, cellStructure, surfaces)`, +bit 33 set — verbatim WB), NOT under the cell's dat fileId; **many cells share +one geometry** (AC dungeons repeat a small palette of tile geometries thousands +of times). + +**The full-bake gate (2026-07-05) proved dedup is mandatory, not optional.** +Baking all 729,888 EnvCells as separate fileId-keyed blobs produced an +**865 GB pak in 52 minutes** — 97% of the blobs were near-duplicate cell +geometry. A prior note here called that duplication "v1-acceptable"; **that was +wrong by ~100×.** Dedup is a v1 requirement. + +**The fix (bake-tool only, no pak format change):** dedup at bake time. +Compute each cell's geomId (cheap — reads the EnvCell/CellStruct header, no mesh +extraction), extract each **unique geometry once**, and emit one TOC entry per +cell-fileId all pointing at the one shared blob offset. The TOC already maps +key→offset with no uniqueness constraint on offsets, and `PakReader` is oblivious +to the sharing (pure offset lookup) — so aliasing needs no format or reader +change. Expected result: ~730K blobs → single-digit-thousand unique blobs, pak +865 GB → a few GB, bake 52 min → minutes (all three collapse from the same fix). + +**MP1c cutover (unchanged):** `RegisterCell` reads `pak[cellFileId]` → the shared +blob → registers under the runtime geomId; post-load dedup continues exactly as +today. Keying blobs by geomId *directly* remains non-viable (the hash exceeds +PakKey's 56 usable bits) — the fileId-key + aliased-offset scheme is why the +format needs no change. + +## 7. MP2 — Distance-degrade port (hide-only first cut) + +The already-scoped retail port from the 2026-06-23 handoff §3 (read it + the named +retail sources FULLY before porting — mandatory workflow): + +- Retail anchors: `GfxObjDegradeInfo::get_degrade` (`0x0051e4b0`, pseudo-C :293086), + `CPhysicsPart::UpdateViewerDistance` (`0x0050e030`, :275517), + `get_max_degrade_distance` (`0x0051e2d0`, :292918), `Render_DegradeDistance` + user setting (:3270). +- **Hide-only cut (this phase):** per-entity max-draw-distance resolved at spawn from + the degrade table; distance check in the entity walk; player + near NPCs exempt from + hiding (handoff caution). Full per-slot mesh selection deliberately lands in MP3 + where the ECS DegradeSystem owns it — accepted small double-touch, avoids building + slot-swap plumbing into a dispatcher MP3 replaces. +- Register bookkeeping: the "no distance-degrade" deviation gets its row updated to + "partial (hide faithful; slot selection pending MP3)" in the same commit; the row is + deleted in MP3's gate commit. +- **Gate:** retail side-by-side is the acceptance (same objects visible/hidden at the + same distances, user-confirmed); drawn-instance count before/after recorded from the + MP0 counters (no invented threshold — retail is the oracle); conformance test on the + `get_max_degrade_distance` math vs decomp. + +## 8. MP3 — ECS render world (Arch) + delta submission (the 300 lever) + +### 8.1 The world + +Arch `World` in `AcDream.App` owning every drawable: statics, baked scenery instances, +live entities, cell objects. Components (all blittable structs): + +- `WorldTransform` (position/rotation/scale, cell-relative frame per #145 rules) +- `MeshRef` (pak mesh handle + part index) +- `DegradeState` (current slot, per-slot table handle) +- `Residency` (landblockId, cellId) +- `RenderFlags` (translucent, hidden, player-owned, …) +- `DirtyTag` (tag component; added on change, cleared by Upload) + +### 8.2 Systems (fixed order, update thread in v1) + +1. **TransformSync** — consumes the simulation's transform/lifecycle events through + ONE seam (single-owner-state rule; the sim never writes render state directly). + Static world entities receive a transform exactly once at residency. +2. **Degrade** — retail `get_degrade` banded slot selection (ideal/max band = no + popping/hysteresis by construction), per entity per frame. Completes the MP2 port; + divergence row deleted here. +3. **Visibility** — frustum + cell/PVS gate (Option A "one gate" preserved from the + render digest — visibility computed once, enforced once). +4. **Upload** — iterates `DirtyTag` entities only; writes changed instance records + into the persistent-mapped SSBO mirror (SoA layout matching the N.5 SSBO), budgeted + per frame. +5. **Draw** — builds the MDI command buffer from the visible set and submits. Instance + *data* is GPU-resident and untouched unless dirty; only commands are per-frame. + GPU compute culling is a measured-need stretch inside this phase, not default scope. + +Steady-state per-frame cost becomes: degrade + visibility iteration (linear over +packed arrays) + uploads proportional to *what changed* (a handful of moving +entities), replacing today's full per-frame walk-and-emit (`WalkEntitiesInto` emitting +every MeshRef of every in-frustum entity every frame + the ~2.1 ms scenery rebuild). + +### 8.3 Encoded lessons (from the DO-NOT-RETRY tables — binding on implementation) + +- Cache/dirty reset gates on actual entity change via tracker (the #53 class). +- Visibility volumes derive from drawn data, never synthetic constants (#119/#128). +- Every GL state the draw uses is set, not inherited (render-self-contained rule). +- Player-owned render state written only at the player chokepoint (#131 class). +- H3 (unbounded live-entity growth across hops) is fixed here structurally: residency + eviction drops render entities (render-only eviction; sim state untouched), + re-materialized on re-entry. + +### 8.4 Conformance + gate + +- **Instance-set diff:** probe dumps the drawn (meshId, transform, slot) set from the + legacy dispatcher and the ECS path on identical fixture frames; sets must match + exactly (modulo MP2's intended hides). +- **Screenshot diff:** fixed camera poses (Holtburg outdoor set + dungeon set + + dense-town set), old vs new, pixel-identical requirement. +- Bring-up happens behind a temporary flag; **the gate commit deletes the legacy + dispatcher path** (no lingering dual pipeline — N.5 ship-amendment precedent). +- **Gate:** diffs green; dense-town steady FPS ≥ 300 OR the MP0 profile names the next + dominant cost (which then decides MP4/MP5 emphasis); user visual gate. + +## 9. MP4 — Zero-alloc frame loop + flat physics data + +**Sequencing constraint: starts only after M1.5 #137 (dungeon collision) has landed** +— it touches the same physics data structures. + +- Allocation audit driven by MP0's per-frame counter: identify every steady-state + allocation site (closures, LINQ, params arrays, list growth); fix via structs, + pooled buffers, `Span`, preallocated scratch. +- Physics consumes the pak's flattened BSP arrays: `PhysicsDataCache` swaps the + managed BSP node graph for index-walks over blittable arrays. Same traversal + order, same arithmetic — layout change only. +- **Conformance:** the existing physics test suites + the trajectory replay harness + must pass unchanged (bit-identical trajectories); that harness exists precisely for + this class of change. +- **Gate:** steady-state allocations/frame = 0 (measured); physics suites green; + traversal p99 re-measured. + +## 10. MP5 — Jobs (stretch, evidence-gated) + +Only if the MP0 profile after MP4 still shows the frame short of target: parallelize +the independent stages (Arch has built-in multithreaded query support; visibility and +degrade are embarrassingly parallel once data is flat). **Explicitly skipped with +recorded numbers if targets are already met** — parallelism is a multiplier, not a +goal. + +## 11.

So **different-class entities that share the low 24 bits collide on the same shadow +part-id.** `ShadowObjectRegistry.Register` calls `Deregister(partId)` before inserting +(`ShadowObjectRegistry.cs:117`), so the second registrant **silently deletes the first's +collision geometry** (last-writer-wins). Rendering uses the full 32-bit `entity.Id` (no overflow), +so every step still *draws*. + +A sibling scheme in the Setup cyl/sphere path (`shapeId = entity.Id + K*0x10000000u`, `:8032/8068/8093`) +is a lesser variant of the same "synthetic per-part id" anti-pattern (can collide across entities), +but the #185 stairs are BSP-bearing so they hit the `*256` overflow specifically. + +### 2.2 Evidence (capture #3, `ACDREAM_PROBE_CONTACT_PLANE` + `ACDREAM_PROBE_BUILDING`) + +- **`[cp-write]`** attributes the contact-plane loss to `Transition.FindTransitionalPosition` (the + forward main-sweep) 530× — i.e. the mover loses grounding at the seam and drops into step-down → + the `PrecipiceSlide` wedge (the "invisible wall"). This is the SYMPTOM. +- **`[bsp-test]` object map** — the collision set has stair steps at world Y = 74.24→77.25 (lower + flight) and 79.25→80.25 (upper flight), with **NO objects at Y≈77.75/78.25/78.75**. The player + climbs the lower flight, floats past its top tread (Y=77.495) into the collision hole, finds no + ground, and wedges. The user confirms the steps there are **visually present** ("steps look + unbroken"). +- **`[entity-source]` part-id collision analysis** — landblock `0xF682` has **23 part-ids with a + collision** (>1 entity → same part-id), including the stair runs themselves: + `0xF6822100 ← {0x40F68221, 0xC0F68221}`, `0xF6821200 ← {0x40F68212, 0xC0F68212}`, + `0xF6822000`, `0xF6822200`, … Overflow check: `0x40F68221*256 & 0xFFFFFFFF == 0xF6822100 == + 0xC0F68221*256 & 0xFFFFFFFF`. + +### 2.3 Why the wedge is a faithful symptom (do NOT fix it) + +Once a step's collision is silently dropped, there is genuinely no ground there, so +`PrecipiceSlide` firing at the walkable edge is *correct* retail behavior for a real edge. The +`PrecipiceSlide` math, the `SetSlidingNormal` Z-zero, and the multi-object search are all +retail-faithful (decomp cross-check `wf_3c1120c4-a04`). Fixing the registration makes the geometry +present, the mover climbs normally, and the wedge never fires. **No change to the frozen collision +internals.** + +## 3. The fix — Option A: register multi-part landblock entities via `RegisterMultiPart` + +**Retail model (the anchor).** A multi-part physics object is one `CPhysicsObj` + `CPartArray`; +collision registration is `CPhysicsObj::add_shadows_to_cells` (0x00514ae0) → +`CPartArray::AddPartsShadow`, which walks the part array and writes each part's shadow into the +flooded cells, **all keyed to the single object** — no synthetic per-part id. +`ShadowObjectRegistry.RegisterMultiPart` is the direct port (its doc cites exactly this). + +**Change (one call site — the per-entity registration block, `GameWindow.cs` ~7876–8100).** +Replace the two synthetic-id `Register(...)` schemes with a single `RegisterMultiPart` per entity: + +1. Build a `List` for the entity, honoring retail's binary dispatch (BSP-xor-cyl, + `feedback_retail_binary_dispatch`): + - If any mesh-ref part has a physics BSP → add one **BSP** `ShadowShape` per BSP part + (`GfxObjId = meshRef.GfxObjId`, `LocalPosition/LocalRotation/Scale` decomposed from + `meshRef.PartTransform`, `Radius = part BoundingSphere.Radius × scale`). + - Else if the Setup has CylSpheres/Spheres/Radius → add **Cylinder** `ShadowShape`s + (same local-offset/scale math as today, but as `LocalPosition` relative to the entity — the + registry rotates by `entityWorldRot` internally). +2. `if (shapes.Count > 0 && !entity.IsBuildingShell) ShadowObjects.RegisterMultiPart(entity.Id, + entity.Position, entity.Rotation, shapes, state:0, flags:None, origin.X, origin.Y, + lb.LandblockId, seedCellId: entity.ParentCellId ?? 0)`. +3. Keep the `IsBuildingShell` skip (building shells collide via the building channel — retail). + +This uses each entity's **unique 32-bit `entity.Id`** as the sole key — no `*256`, no +`+K*0x10000000`, no overflow, no collision — and **unifies the codebase on the one faithful +multi-part registration path** (the door + every server entity already use it). It removes the +redundant per-part loop. + +**Despawn.** Landblock unload must `Deregister(entity.Id)` (not the old synthetic part-ids). Verify +the unload path deregisters by `entity.Id`; adjust if it currently targets `partId`. + +**Explicitly NOT changed:** `PrecipiceSlide`, `SetSlidingNormal`, the collision response, the +step-down chain — all verified faithful; the symptom disappears once geometry is present. + +## 4. Alternatives considered + +- **B — widen the shadow-registry key to `ulong`** (`partId = ((ulong)entity.Id<<8)|partIndex`). + Keeps the non-retail "each part is its own shadow object with a synthetic id" model, merely + de-overflowed; fragments one retail object into N pseudo-objects; leaves two parallel + registration paths. Rejected — less architectural, less faithful. +- **v1 Approach A (grounding retention)** — disproved (§ v2 note): the continuation isn't in the + collision set to retain grounding on. + +## 5. Test strategy + +- **Red→green unit pin (Core):** `ShadowObjectRegistryOverflowTests` — register two entities whose + ids collide under the OLD `*256` scheme (e.g. `0x40F68221`, `0xC0F68221`) as multi-part; assert + BOTH remain queryable in their cells (OLD scheme: one overwrites the other; NEW: both present). + Drive via `RegisterMultiPart` + `GetObjectsInCell`. +- **App-layer pin:** a focused test over the registration helper (extracted if needed) that feeds + two colliding-id multi-part entities and asserts two distinct registrations survive. If the + registration logic is buried in `GameWindow`, extract the shape-list build + register into a + small testable method (`LandblockEntityCollisionRegistrar`) per Code-Structure-Rule 1. +- **Keep the dat-free clean-climb replay** (`Issue185OutdoorStairsSeamReplayTests`, already written + + passing) as a regression pin (continuous stairs must climb). +- **Regression:** `ShadowObjectRegistryTests`, `ShadowObjectRegistryMultiPartTests`, + `DoorBugTrajectoryReplayTests`, `Issue137*`, `CellarUp*`, `SphereCollisionFamilyTests` green; + full `dotnet build` + `dotnet test`. +- **Live gate (acceptance, user):** walk up the FULL staircase — no jam, no jump; plus a spot check + that torches/trees/other statics still collide (the registration path is shared). + +## 6. Apparatus / fixtures (captured this session) + +- `185-recapture3.jsonl` + task `.output` (`[cp-write]`, `[entity-source]`, `[bsp-test]` object map). +- Overflow analysis (23 collisions) reproducible from the `[entity-source]` log. +- gfxobj dumps `Fixtures/issue185/0x01000AC5.gfxobj.json` (+ `0x01000ACA`) for the replay. + +## 7. Bookkeeping (in the fix commit) + +- Register: this is a bug fix (not a new deviation); if a row implied the old per-part id scheme, + none does — no register row needed, but note the fix in the ISSUES close. +- `docs/ISSUES.md`: move #185 to Recently closed with the SHA. +- `claude-memory/project_physics_collision_digest.md`: banner — #185 was a REGISTRATION overflow + (part-id `*256` uint collision), NOT a collision-response bug; the wedge was a faithful symptom. + DO-NOT-RETRY: don't chase the wedge/precipice; the fix is the registration id. + +## 8. Acceptance + +- Local player walks up the full outdoor staircase, no jam/jump. +- No collision-id collisions in a landblock (the 23-collision analysis returns 0 after the fix). +- Other landblock statics (torches/trees/buildings) still collide; suites + build/test green. + +## 9. DO-NOT-RETRY + +- Do NOT touch `PrecipiceSlide` / `SetSlidingNormal` / step-down — the wedge is a faithful symptom + of missing geometry, not the cause. +- Do NOT "widen the key" (Option B) — it preserves the non-retail synthetic-per-part-id model. +- Do NOT reintroduce a synthetic per-part id (`*256` or `+K*0x10000000`) — the retail model is one + object id + a part array (`RegisterMultiPart`). diff --git a/src/AcDream.App/AcDream.App.csproj b/src/AcDream.App/AcDream.App.csproj index d50c6b46..c07ae6c3 100644 --- a/src/AcDream.App/AcDream.App.csproj +++ b/src/AcDream.App/AcDream.App.csproj @@ -38,6 +38,7 @@ + @@ -50,6 +51,11 @@ PreserveNewest + + + PreserveNewest + diff --git a/src/AcDream.App/Diagnostics/FrameProfiler.cs b/src/AcDream.App/Diagnostics/FrameProfiler.cs new file mode 100644 index 00000000..2ac85dcd --- /dev/null +++ b/src/AcDream.App/Diagnostics/FrameProfiler.cs @@ -0,0 +1,213 @@ +using System; +using System.Diagnostics; +using System.Globalization; +using System.Text; +using AcDream.Core.Rendering; +using Silk.NET.OpenGL; + +namespace AcDream.App.Diagnostics; + +/// Stage indices for per-frame CPU attribution. +public enum FrameStage +{ + /// Whole OnUpdate body (simulation + streaming apply). + Update = 0, + /// WbMeshAdapter.Tick — staged mesh/texture GPU upload drain. + Upload = 1, + /// ImGui Render (dev overlay). + ImGui = 2, +} + +/// +/// MP0 (2026-07-05) — the permanent honest frame profiler.
