Erik 02a8288172 feat(render): S3 chunk 1 — print-only walk transcript, OH fixtures, offline signature diff 
Campaign OVERHAUL S3 chunk 1 (docs/research/2026-09-01-overhaul/s3-walk-ownership-map.md
§11): the transcript-kinds/fixtures/print-only-emitter half of the walk work,
built AFTER chunk 3 landed LC/SC (the per-land-cell interleave).

B1 — the emitter (print-only, never gates admission/depth/order):
- ACDREAM_DUMP_WALK_TRANSCRIPT=1 is read once into RuntimeOptions.DumpWalkTranscript
  (rule 4) and handed to RenderingDiagnostics.DumpWalkTranscriptEnabled (rule 5,
  a settable static, not a second env read) once at GameWindow construction — the
  deep walk call sites have no reachable RuntimeOptions reference.
- WalkTranscriptDump (new) prints the OH line kinds — F/P/LS/LC/SC/BLD/DI/DC/EC/OC —
  to Console at the exact points retail's cdb breakpoints sit
  (tools/walk-oracle/oh/oh-capture-walk.cdb.template), gated internally so every
  method bails out before any string work when the flag is off.
- Every call site lives in WalkFrameDriver.cs, at the point the driver already
  processes that turn: Collect (F/P, after BeginFrame), Emit's DI/LS/DC/BLD cases,
  OnLandCellTurn/OnLandscapeCellTurn (LC/SC, at LOD resolution via the new
  WalkTranscriptDump.LodCellId helper, before the 8x8-bucket expansion), and the
  EmitFloodTurns/EmitCellContentsTurn loops (EC/OC — both UNCONDITIONAL per flood
  visit, matching the OH captures' always-equal EC/OC counts; retail's own
  DrawEnvCell stamp dedupe sits past the breakpoint, inside the function).
- DC's "pv=" field encodes interior(0)/outdoor(1) as an 8-hex-digit 0/1 so it
  satisfies the same pv=[0-9a-f]{8} regex real captures use; derived from
  _currentDcStage at the DC event (CellStatic = interior pview, else outdoor).
- The frame-root pose (origin, quaternion) is a reasonable orthonormal basis built
  from the walk's own CyPlane.Normal forward vector and WalkLandscape's own
  ViewerWorldOriginX/Y block origin — self-consistent for the round-trip parser,
  not a byte-exact reproduction of retail's Frame (B4's diff never compares P).

B2 — WalkOracleTrace learns EC/OC event kinds (LC/SC already existed from chunk 3).
New WalkOraclePartsTrace.cs holds two small read-only parsers for the parts log
(PD/DM) and the alpha-depth log (AM/FL/PM/PC) — records only, no validator, no
canonical JSONL, no new tool.

B3 — fixtures: the five OH walk captures join WalkOracleTraceTests.AllFixtures
(now (root, name) pairs — FW0's own root plus the OH capture directory) for
parse + complete-frame pins. The four kit poses join WalkTraceConformanceTests'
still-fixture coverage as NEW rows (the OH cathedral-arrival root is f4180108,
not FW0's f4180106): terrace-edge/cathedral-arrival extend the existing theory
(now (root, fixture) parameterized); holtburg-doorway-still and foundry-deep get
dedicated tests mirroring their FW0 siblings' own structure. Finding: the OH
foundry-deep capture's own retail transcript draws 12 real town buildings through
its exit chain (unlike the FW0 capture, which apparently reached none at that
pose) — the FW0 test's stub 1x1 landscape undershoots it (first divergence:
nothing after "LS" vs retail's real BLD content); fixed by building the full
landscape/building world via WalkLandscapeDatBuilder.Build, matching the shared
theory's own approach, not by skipping or weakening the row.
WalkTraceReplayContext.Signature(WalkOracleFrame) now filters to the DI/DC/BLD/LS
kinds (LC/SC/EC/OC never had a WalkEvent analogue in RetailFrameWalk's own
four-kind vocabulary) instead of mapping them to a "?" placeholder, so the still-
fixture comparison stays apples-to-apples on both sides.

B4 — WalkTranscriptSignatureDiff (test-side only, no runner/tool): diffs two
transcripts (raw lines or parsed frames) at the full DI/DC/BLD/LS/LC/SC/EC/OC
level, reporting the first divergent event and position per frame. Proven over a
synthetic self-vs-self-minus-one-event pair (SignatureDiff_ReportsTheExactRemovedEvent).

Tests: T1 (flag off) is split into a unit-level zero-allocation/zero-output check
on WalkTranscriptDump itself (the walk's pre-existing allocation, e.g.
RetailFrameWalk.EmitDrawCells's per-call array, is untouched by this chunk and not
independently zero-alloc) and an integration-level Collect() check; both assert via
WalkOracleTrace.Parse returning zero frames rather than raw string equality, which
is robust to unrelated Console.WriteLine noise from other test classes running in
parallel (a real, observed hazard — WalkFrameDriverTests joins
CameraDiagnosticsCollection for the same reason CornerFloodReplayTests/
Issue181WallPressEquilibriumTests already do, issue #251). T2 proves the
emitter/parser round trip on a synthetic interior frame. T3's InstalledDat rows all
pass. T4: LaunchOptionsDocumentationTests green with the ACDREAM_DUMP_WALK_TRANSCRIPT
row (both directions).

Gates: hermetic lane 6,814/0 (was 6,795 baseline + new tests), three consecutive
clean runs; InstalledDat lane 245/3 known-failures (the two pre-existing #383
layout tests + TowerAscent) unchanged from baseline.

acdream documentation map

This page is the entry point for project documentation. It distinguishes current sources of truth from implementation history so an old plan or issue banner cannot silently override the current program state.

Current snapshot — 2026-07-27

  • Milestone state: M3, “Cast a spell,” landed 2026-07-21. M4, “Live in the world,” is active.
  • M4 gameplay program: resume the pre-M4 world-interaction completion program. Favorite-spell overflow, status Use/Assess, and the complete assessment surface are user-accepted. Equipped-child picking and vendor browse/transactions remain Slices 4–6.
  • Structural/runtime state: all eight GameWindow decomposition slices, Modern Runtime Slices A–J, and the connected visual/lifecycle gates are complete. GameWindow is a 1,622-line composition/callback shell. AcDream.Runtime.GameRuntime owns canonical session, entity/object, gameplay, movement, physics, projectile, environment, and portal state; graphical and no-window hosts borrow the same owner graph.
  • Headless state: Slice K is complete. AcDream.Headless is a presentation-free Windows/Linux host with deterministic commands/events, shared immutable content, multi-session isolation, reconnect, resource telemetry, and 1/5/10/30-session gates. The final two-account native-Linux soak completed ten minutes, logged out through ACE, and converged every ownership ledger.
  • Linux graphical state: Slice L0 and the L1 implementation checkpoint are complete at 66f114b2 and 11501d52. Native Windows passes the active modern-GL/audio/window smoke. WSLg X11/Wayland correctly reject their missing GL_ARB_bindless_texture. Physical-Linux validation and L2–L6 are explicitly deferred; resume at the supported AMD/NVIDIA L1 gate.
  • Completed gameplay gates: R6 locomotion/collision/projectile/teleport/ radar, two-client portal-out/materialization, indoor prepared collision, loot ordering, local/remote ground drops, and selection-marker lifetime.
  • Separate visual verification: issue #225, the shared-alpha lifestone/particle result; its connected resource-lifetime and performance routes pass.
  • Carried behaviour debt: issue #153 (far teleport onto an unstreamed edge), #116 (narrowed slide response), #235 (capped/RDP jump cadence), and the active temporary-stopgap rows in the divergence register.
  • Divergence audit: 189 active rows — IA 18, AD 38, AP 91, TS 38, and UN 4 — plus retained struck/retired historical rows such as TS-37.
  • Latest automated baseline: the Release build succeeds with the 17 test-project warnings tracked by issue #228; 8,826 tests pass and five are intentionally skipped. App passes 3,763 / 3 skips. The L1 Windows supported smoke and WSLg X11/Wayland negative-capability reports all end with zero window/GL/input/audio ownership.

Sources of truth

Read these in this order when deciding what to do next:

  1. plans/2026-05-12-milestones.md — the active playable outcome, freeze boundaries, and visual gates.
  2. plans/2026-04-11-roadmap.md — strategic phase ledger: shipped, active, deferred, and future work.
  3. ISSUES.md — tactical defects and small follow-ups. The status inside an issue is authoritative; physical order is not.
  4. architecture/retail-divergence-register.md — every known place runtime behavior can differ from retail.
  5. architecture/acdream-architecture.md and architecture/code-structure.md — ownership, dependency, update-thread, and extraction rules.
  6. architecture/worldbuilder-inventory.md — rendering/DAT code already owned in-tree versus mechanisms still ours to port.

If these disagree, milestones control the current outcome, the roadmap controls work ordering, the issue status controls the individual defect, and the architecture documents control implementation shape. Reconcile the stale document in the same change; do not leave both claims standing.

Research and implementation records

  • research/named-retail/ is the primary retail oracle: named pseudo-C, headers, symbols, and types from the Sept 2013 build.
  • research/decompiled/ is the older Ghidra fallback.
  • research/ contains focused pseudocode, traces, fixtures, and gate reports. A dated research note records evidence; it does not become a new roadmap.
  • superpowers/specs/ and superpowers/plans/ are per-slice design and execution records. Completed plans remain historical.
  • ci-and-releases.md is the SSOT for the Gitea CI pipeline, the self-hosted runners, and how alpha releases are published. Load-sensitive tests live in Lane=Timing; see release-gate.md before adding to it.
  • launch-options.md is the SSOT for every environment variable and command-line argument the client reads, including what each one changes about the run beyond its obvious effect. Read the side-effects column before trusting any measurement. Enforced by LaunchOptionsDocumentationTests: a flag without a row fails the build, and so does a row whose read site was deleted.
  • audit/ contains completion and conformance audits.
  • reference/ace-commands.md preserves the local ACE server's complete in-game command catalog and points to the authoritative per-command help surface.

Durable memory

  • ../claude-memory/MEMORY.md indexes the live subsystem memories and the render/physics digests. Read a domain digest before changing that subsystem, especially its DO-NOT-RETRY table.
  • ../memory/ contains stable engineering references such as the modern rendering pipeline, two-tier streaming, and toolchain notes.

Memory accelerates recall; it does not outrank the canonical documents above. When current truth changes, update the relevant canonical document and distill only the durable lesson into memory.

Historical and deprecated documents

  • bugs.md is the April 2026 bug snapshot. It is preserved for archaeology and is not an active ledger.
  • Dated plans and specs describe the decision at that time. Their completion wording is historical unless the current milestone/roadmap explicitly links the item as active.
  • Old R1→R8 architecture sequencing is superseded. Current execution comes from the milestones and strategic roadmap.

Documentation maintenance rules

  • Update milestone, roadmap, issue, divergence, architecture, and memory claims in the same commit when a shipped change affects them.
  • Keep one issue ID per defect. Narrow an issue in place; do not reuse another issue's number as a shorthand.
  • Mark automated, connected, and visual gates separately. An automated pass is not a visual acceptance, and an RDP throughput sample is not a local-display visual comparison.
  • Preserve research history, but remove stale “current/next” claims from living documents once the state advances.
