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.

Render::deg_mul is auto-tuned by frame load and SWUNG between oracle
captures: doorway-still ran right after the heavy terrace-edge capture
with the multiplier depressed (mul <= 0 puts thresholds at/below ideal,
so 001e/0026/002f select the portless level 1 - retail's zero look-in
floods, reproduced exactly at mul = 0), while every other fixture pins
~ +0.99 (thresholds at max). The recon session's "-0.99" live dump was
real - taken under the same cdb load. RetailFrameWalk now exposes the
multiplier; the doorway test pins 0, the rest use the default.
foundry-entry: frames 1-66 reproduce exactly; the F67-F79 standing
segment diverges ONLY in building 0036's intra-building DC order
(retail 116,118,11d vs replay 11d,116,118). The BSP-traversal microscope
pins the flip to 0036's ROOT plane (N=(0,0,-1) D=2.8): replay eye z
2.33 (d=+0.47, NEG-first) vs retail behaving as d<0 (POS-first) - a
structural ~0.5 m frame question (positionPush(2)/part-scale), only
adjudicable live. Turnkey probe:
tools/walk-oracle/fw1-f67-viewpoint-probe.cdb.
Fixture status: nine of ten fully conformant; foundry-entry exact
through F66 with the 13-frame order segment parked on the probe.
Suites: Walk 127/1 skip; hermetic 6,687/0.

The moving-fixture divergence was the building degrade ladder:
GfxObjDegradeInfo::get_degrade @0x0051e4b0 (Ghidra-verified - BN's
FPU-flag pseudo-C misread BOTH arm selection and one formula) slides
each level's threshold from ideal toward MAX as the multiplier
approaches 1, and the live client runs the positive arm at ~0.99, so
level 0's portal-bearing BSP survives to ~max_dist (48 for the Holtburg
cottages), not ideal (24). The recon note's "deg_mul = -0.99" was a
sign misread; the negative arm's threshold slides toward MIN and
contradicts the fixtures from both directions. With the two-arm port,
holtburg-walkout, holtburg-transitions, and holtburg-walkabout pass
every pairable frame - the walkout-F2 microscope's prediction
(103,100 | 100x3 | 124 through the cottage exit views) landed exactly.
Also this round, falsified and reverted: a BN-driven swap of the
portal walker's negative/in-plane arms (Ghidra shows side 1 = negative
EMITS, side 2 = in-plane does not - the original port was correct; the
swap broke four fixtures). The walker docs and unit tests now pin the
Ghidra-verified truth table.
Parked with findings: foundry-entry F67 (right flood set, one
plane-side classification at the +/-eps boundary orders 11d before
116/118) and doorway-still (retail shows zero floods at a pose one
meter from walkout-F2's flooding pose; multi-portal clip boundary).
Suites: Walk 124/3 skips; hermetic 6,687/0.

The moving driver gains adjacent-pose tolerance (the marker-lag capture
artifact) and stays parked: the four moving fixtures diverge at
punch-edge frames under BOTH adjacent poses. FALSIFIED this round and
reverted: the raw-decode + flipped-gates convention (it broke three
still fixtures - the inverted-decode convention stands, six still
fixtures frame-exact). Remaining instruments in the Skip note: znear,
per-view punch ordering inside DrawMesh, exit-view precision.

Three final pins complete the still-fixture set: (1) the CELL portal
side decode is the INVERSE of the 0x2 bit (uniform with the building
convention; the doorway-still flood proved it - ov=2 n=3 exact, and
foundry-deep stays green); (2) interior frames key the landscape order
off the OUTSIDE-projected landcell (get_outside_cell_id - derived from
the camera origin); (3) the outdoor pview has draw_landscape=FALSE so
look-in floods discard exit portals - the ov=0 pattern of every traced
look-in. CONFORMANT: foundry-deep (every frame), doorway-still,
street-outdoor, terrace-center, terrace-edge (the #456 acceptance
pose), cathedral-arrival - full frames identical to retail. The moving
four diverge only at punch-edge frames (walkabout F9, foundry-entry
F67) - pose-timing sensitivity parked in the driver Skip note.

The moving-fixture sweep pinned the pose decode (quat storage w,x,y,z;
facing = rotated +X; the consistent triple right=-rot(Y), fwd=rot(X),
up=rot(Z) - mean 20.8 deg vs motion, alternatives >=52). With it the
street-outdoor BLD roster and order match retail EXACTLY except one
ring-1 boundary pair (aab50002 extra / a9b3003c missing). Look-in
punches fire at the wrong buildings under BOTH GfxObj plane-winding
conventions (retail punched only 001a and 0022 into the a9b4016x
cells) - the next adjudication targets the PortalRef.PortalIndex join
and the BuildingPortal side-flag decode via a per-building dump. The
driving diff test carries the state in its Skip note; the flip toggle
stays for the next arm.

WalkLandscapeDatBuilder assembles the replay grid with the LIVE-dumped
retail landscape model (LScape mid_radius=25 -> 51x51; the resolution
pyramid observed on the capture client: side_cell_count 8 in the 3x3
core, 4 at ring 2, 2 at rings 3-4, 1 beyond; buildings attach only to
full-res blocks - matching the traces roster), retail z-slabs
(heightTable[max]+200 / [min]-1 per CLandBlock unpack @0052f297), and
camera-block-local coordinates. The replay context gains the building
half (placements, active-view install, building-polygon clip). The
street-outdoor conformance diff now reaches real adjudication: the walk
over-culls six traced buildings (jagged boundary - not a clean frustum
edge) and the look-in floods differ; the driving test is parked Skip
while the visibility map is instrumented.

The replay harness reconstructs the camera from a pose-stamped oracle
frame (Frame quaternion w,x,y,z storage order; +Y forward / +Z up;
landblock-local origin) and drives the ported walk over adapter-built
cells (cell transforms from EnvCell.Position now populated). The
foundry-deep fixture - the pure-interior frame shape - reproduces
retail EXACTLY on every complete frame: DI + DC(ov=0, [cell]) with no
landscape, 39/39. Conventions are now pinned by live retail output; the
remaining nine fixtures need the outdoor world build-out (landscape
blocks, terrain z-slabs, building transforms + active-view clip) and
join the same gate.
