Fix round 1 of the two the plan allows for S4-c2 (048d5b12f), addressing
every item M1-M8/A1-A8 from the campaign branch's packet section 11.
M1 (BLOCKING): ParticleRenderer.DeferToRetailAlphaQueue threw whenever a
mesh-particle batch's TranslucencyKind.Opaque classification (mask 0x00)
reached a non-Append DrawMesh row - a real, reachable outcome since
TryAppendMeshDraws applies no IsOpaque-style pre-filter unlike
WbDrawDispatcher's path. Deleted both throws (ParticleRenderer.cs,
WbDrawDispatcher.cs SubmitToAlphaQueue), extracted the router-input
derivation into internal static ParticleRenderer.RouteParticleSubmission
(directly testable), and implemented rows 1/5's immediate draw by reusing
the existing per-instance billboard/mesh draw code (new
DrawImmediateParticleSubmissionRhi, no new renderer, no sort per A8).
materialHasAlpha (row 4) is derived from CMaterial::CheckAlphaValues
@0x005396a0 (Ghidra-verified 2026-09-04): has_alpha=0 only when
Ambient.a==Diffuse.a==Specular.a==Emissive.a==1.0f, else 1 - and
CMaterial::SetTranslucencySimple @0x005396f0 (reached from
CPhysicsPart::SetTranslucency <- Particle::Update @0x0051c290's per-frame
alpha-fade) sets all four channels to (1f - translucency) uniformly, so
has_alpha == "this particle's current alpha isn't 1.0" - already carried in
ColorArgb's top byte (Lerp(StartAlpha,EndAlpha,tLife), ParticleSystem.cs
1039-1041/1453).
M3: SubmitToAlphaQueue now takes isBuildingShell + viewProjection and feeds
Row 1's detailSurfaceActive gate for translucent building-shell instances
(retail DrawBuilding @0x0059f2a0 installs building detail before its own
shell subsets reach DrawMesh). Row 1 (detail on) draws the instance
immediately at its own walk-stream AlphaSubmitMark via new
DrawImmediateAlphaInstance/DrawImmediateAlphaInstanceRhi (reusing
WriteDeferredAlphaEntrySlot + the drain's pipeline/detail code for slot 0);
never touches _deferredAlpha/the queue for pure-Immediate submissions (fixes
a latent leak: previously reserving a _deferredAlpha slot for every
candidate meant a frame with ALL-immediate content never registered a
source, so ResetAlphaSubmissions never ran). M3c: DrawPreparedAlphaBatchRhi's
own per-command hasDetail/DrawBuildingDetailRangeRhi branch is deleted -
detail-eligible content no longer reaches the drain (spec: delayed replay
is always detailEnabled=0). New AD-120 register row for the "in place -> at
the entity's own stream mark" granularity adaptation this introduces.
M6: RetailPViewPassExecutor.SubmitOrDrawTransparentCellShell routes an
EnvCell's transparent shell through the SAME RetailAlphaMeshRouter table
(mask 0x02, detailSurfaceActive = EnvCellRenderer.TransparentDetailEnabled)
instead of a hand-coded branch. Detail on: unchanged immediate draw. Detail
off: appends ONE token per CELL via new EnvCellAlphaDrawSource (internal,
delegate-based so it's unit-testable without a GPU harness), replayed
through EnvCellRenderer.RenderTransparentOrdered at the next flush -
RenderTransparentOrdered already replayed a cell's batch on demand, so no
new deferred-replay abstraction was needed (the original landing's claim
that one was required is corrected in the packet).
M4: RetailAlphaEntry.IsFirstForList deleted. Retail's per-DrawMesh-
invocation "first for this list" flag is trivially true for every subset
retail ever appends (DrawMesh @0x0059d4a0 sets both flags true at entry,
0059d4cc/0059d4d0, clearing each independently after ITS OWN first append
within that call, 0059d5ef) - the captures confirm it (new=1 on 9,685/10,556
AM lines, impossible under "first since last drain"). acdream's deleted
isFirstForList = target.Count == 0 computed the wrong quantifier. One
acdream append already IS one DrawMesh call, so the field carried no
information and its own pin was vacuous (feedback_every_new_pin_must_be_
shown_to_fail) - deleted rather than kept as an always-true no-op.
M5: split all six AlphaFlushTranscript_* KnownFailure Facts into live
AlphaFlushSites_* (site+threshold sequence only, content-independent,
unconditional pass) and AlphaFlushCounts_* (KnownFailure, full tuple incl.
drained counts) sharing one RunAlphaFlushTranscriptReplay helper. Rewrote
the KnownFailure reason honestly: THREE independent causes, not "harness
content only" - (1) zero live mesh content, (2) acdream appends one entry
per INSTANCE vs retail's one per SUBSET per DrawMesh call, (3) acdream's
CLIP list is structurally empty for ordinary content (M2). Added ONE live
valve pin (WalkFrameDriverTests.SortCellExit_ValveDrainsThroughReplayAtThe
ExactBoundary, a Theory over 2250/2249) that goes through WalkFrameDriver.
Replay's own SortCellExit arm, not RetailAlphaQueue.Flush called directly.
M2/A2/M8c (register): ~~AP-34~~ restored as struck-through RETIRED (it had
been deleted outright, not struck, breaking the register's own convention)
citing residuals AP-238/AP-239/AP-240. The chunk-2 commit's "AP-236"/
"AP-237" collided with an id ALREADY filed-and-retired on main by an
unrelated #132 fix (docs/ISSUES.md:19976) - ids are never reused, so both
are renumbered: AP-236->AP-238 (EnvCell; rewritten per M6 - granularity-only
residual now, "never through the shared queue" is retired), AP-237->AP-239
(mask-reconstruction gap; the dangling "AP-236b" citation in
RetailAlphaMeshRouter.cs never matched either filed id and is corrected to
AP-239). New AP-240 filed for M2: WbDrawDispatcher.IsOpaque filters
ClipMap out upstream, so ordinary clip-mapped content never reaches
retail's CLIP FIFO (draws immediately on the pre-existing
OpaqueAlphaToCoverage pipeline instead) - no pipeline change this round,
per the contract. AP section header recounted honestly: 159 active (was
stale at 161); AD section 92 (was 91, +AD-120).
M7: AP-239's only cited example (cloud GfxObj 0x01004C35, surface
0x08000023) is DISPROVEN - decoded Type=0x10114 has alpha-family bits
that win in BOTH retail's real priority and acdream's reconstruction, so it
never actually diverges. A 2026-09-04 scan of all 6,152 Portal-dat Surfaces
found 27 real Translucent+Base1ClipMap-no-alpha-family instances
(Type=0x14); cross-referencing GfxObjs found surface 0x08000015 on GfxObj
0x010001EC - cited in place of the disproven cloud example.
M8: (a) RenderDeviceD3D::DrawBlock is @0x005a17c0 per symbols.json, not
@0x005a18d0 (that is its per-land-cell loop head) - fixed across
RetailAlphaQueue.cs, RetailPViewPassExecutor.cs, WalkEvents.cs,
WalkFrameDriver.cs (x3), RetailFrameWalk.cs. (b) RetailAlphaQueue.cs's four
FlushAlphaList addresses were labelled "return site" but are the CALL
instruction's own address (x86 CALL rel32 is 5 bytes) - relabelled "call at
X (returns to X+5)". (d) worldbuilder-inventory.md:420's AP-34 citation
updated.
A1: RetailPViewRenderer.cs's outdoor-root passes.FlushLandscapeAlpha() call
(labelled LandscapeFlush) is deleted - retail's real LandscapeFlush
(PView::DrawCells @0x005a4840's own FlushAlphaList(0f) @0x005a4872) sits
strictly inside if (outside_view.view_count > 0) on the INTERIOR PView; an
outdoor root never reaches it (terrace-edge capture: zero 005a4877 FL
lines). Verified no opaque draw intervenes between this deletion point and
RetailAlphaQueue.EndFrame()'s own RenderNormalMode pass-end flush
(WorldSceneRenderer.cs: DrawPostWorldParticles's PView branch is an
explicit no-op; only diagnostic wireframes follow) - #132's "drain after
the finished opaque world" invariant is kept by that flush alone.
A4: RetailAlphaQueue's ApplyScratchRetention call sites passed the ENTRY
count as the SOURCE-count argument too (observedClip + observedAlpha
twice), so _sources/_sourceDrawOffsets never shrank toward the real source
count. Fixed to capture _sources.Count before Clear().
A5/A6/A7: WalkStaticStreamPopulatorTests.cs's stale "same viewer distance"
banner corrected; two off-by-one entry counts in the packet's section 10
sequences corrected (foundry-deep x10->x11, holtburg-doorway-still x5->x6);
WalkAlphaDepthTrace.cs's "new=" comment explains why IsNew is retained but
never compared (M4's finding makes a per-subset comparison meaningless at
acdream's per-instance granularity); RetailAlphaMeshRouterTests.cs's
IndependentReferenceRoute (never actually independently-shaped) renamed to
RestatedBranchTableRoute with an honest doc comment, and the unverified
"flipped in turn and failed every time" claim deleted.
A3 was resolved as a side effect of M1's SubmitToAlphaQueue doc-comment
rewrite (the wrong "0x02/0x03, 0x04/0x05, 0x08/0x09" enumeration no longer
exists); RetailAlphaMeshRouter.cs's own MaskFromTranslucencyKind comment
updated in the same spirit (M1's particle-site Opaque-reachability finding).
Mutation checks (each applied to a scratch-restored copy, confirmed
failing, then byte-exact reverted - diffed against a /tmp backup after
restore):
- A1 (RetailPViewRendererTests.DrawInside_NeverCallsFlushLandscapeAlphaDirectly):
restoring the deleted "if (ctx.RootCell.IsOutdoorNode)
passes.FlushLandscapeAlpha();" line reintroduces a direct
RetailPViewPassExecutor.FlushLandscapeAlpha call in DrawInside's compiled
body. Actual failure: "Assert.DoesNotContain() Failure: Filter matched in
collection ... CompiledCall { ... Target = Void FlushLandscapeAlpha() }".
- A4 (RetailAlphaQueueTests.RetainedSourceCapacity_ConvergesToTheReal
SourceCountNotTheEntryCount): reverting both ApplyScratchRetention calls
to (observedClip + observedAlpha, observedClip + observedAlpha) - with
100 distinct sources in the spike frame (so _sources.Capacity grows to
128, past its initial 4) followed by three low-demand frames of 10
entries via ONE repeated source - makes sourceTarget compute from 10
(Math.Max(4,10*2)=20) instead of 1 (Math.Max(4,1*2)=4). Actual failure:
"Expected the retained source-array capacity to converge toward the real
source count (1), but it stayed at 20". (A single-source-only spike does
NOT discriminate this bug - Math.Min(sourceTarget, _sources.Capacity)
clamps both formulas to the same unchanged initial 4 - hence the
100-source setup.)
- M5 valve (WalkFrameDriverTests.SortCellExit_ValveDrainsThroughReplayAt
TheExactBoundary, 2250 case): flipping RetailAlphaQueue.Flush's no-op
comparison from "<" to "<=" (S4-c1/c2's own boundary mutation) makes the
2250-entries case a no-op instead of draining. Actual failure:
"Assert.Equal() Failure: Values differ Expected: 0 Actual: 2250".
- M6 (EnvCellAlphaDrawSourceTests, both Facts): adding an immediate
renderTransparentOrdered(new[]{cellId}) call inside
EnvCellAlphaDrawSource.AddPendingCellId (simulating the M1/M3 "drew
immediately instead of deferring" bug class) makes
PendingCellToken_IsDrainedAtTheFlushAndNeverBeforeIt fail with
"Assert.Empty() Failure: Collection was not empty Collection: [[4660]]"
and ParticleAppendedBetweenTwoCellTokens_KeepsItsPositionInTheCombined
Drain fail with 'Expected: string[] ["cell:256", "particle:7",
"cell:512"] Actual: List<string> ["cell:256", "cell:512", "cell:256",
"particle:7", "cell:512"]'.
- M1 (ParticleRendererRouteTests.OpaqueClassifiedMeshBatch_WithMaterialAlpha
_RoutesToAlphaAppend): hardcoding materialHasAlpha to false inside
RouteParticleSubmission makes the Opaque-mask+has-alpha case route
Immediate instead of Append. Actual failure: "Assert.Equal() Failure:
Values differ Expected: Append Actual: Immediate".

Replaces the single scope-global distance-sorted RetailAlphaQueue with
retail's own two independent FIFO lists (CLIP/ALPHA, capacity 3000 each,
D3DPolyRender::AddMeshToAlphaList's exact append-only/capacity-drop
behavior — Ghidra-verified 2026-09-04), routed by a new
RetailAlphaMeshRouter porting DrawMesh's five-row immediate/delayed
branch table and ConstructMesh's subset-mask formula as pure functions,
and drained at retail's four normal-world FlushAlphaList sites
(DrawBuilding/DrawBlock/PView::DrawCells/RenderNormalMode) under the
exact Ghidra-verified no-op predicate (both counts strictly below
threshold*3000). A new WalkFrameEventKind.SortCellExit /
IWalkEventSink.OnSortCellExit / IWalkFrameLeafRenderer.FlushSortCellExit
fires once per admitted land-block cell for DrawBlock's 0.75f valve,
pinned by a dedicated far/near ordering test in RetailFrameWalkTests.cs.
WbDrawDispatcher's two submit sites and ParticleRenderer's one route
through the router; since none of the three ever draws during the Sky
leaf, installs a detail surface, or sets MultiPassAlpha, rows 1/2/4/5
are provably unreachable there and the call sites assert loudly rather
than building unexercisable immediate-draw plumbing. FlushFartherThan,
RetailAlphaOrdering.ComputeViewerDistance, and every viewerDistance
argument on the submit path are deleted.
Scope note (packet s4-depth-alpha-packet.md §10): C4 (routing EnvCell's
transparent shell batches through the shared queue) was not attempted —
EnvCell draws one per-cell MultiDrawIndexedIndirect call with no
per-subset deferred-replay abstraction, and building one without visual
verification (no graphical client in this worktree) was judged out of
this bounded chunk's scope. AP-34 is therefore retired and replaced by
two narrower rows rather than deleted outright: AP-236 (the carried-
forward EnvCell-immediate residual) and AP-237 (a newly identified gap:
TranslucencyKind.AlphaBlend can arise from either retail's Alpha/
Translucent bits, mask 0x02/ALPHA, or the Translucent+ClipMap "cloud"
override, mask 0x08/CLIP — GroupKey doesn't retain the raw bit to tell
them apart, so the router always picks ALPHA; only known example is
cloud GfxObj 0x01004C35). Both are compositing-order-only divergences,
never blend/visual ones.
Mutation checks (each applied, confirmed failing, then reverted):
- FIFO drain order reversed -> 5 RetailAlphaQueueTests fail (order).
- FlushAlphaList `<` -> `<=` -> boundary/scratch tests fail (2250 case
reads drained=0 instead of 2250).
- Capacity check loosened (3000 -> 6000) -> overflow-drop test fails
(TryAppend returns true, PendingCount reads 3001).
- IsFirstForList forced true -> flag test fails once inspected on the
pre-flush two-entry snapshot (the post-flush single-survivor version
of this test was vacuous and rewritten).
- Router row 3 condition inverted -> both the hand-traced Theory (6
cases) and the 160-cell independent-truth-table brute force fail (20
mismatches).
- SortCellExit emitted before OnLandscapeCellTurn instead of after ->
RetailFrameWalkTests ordering pin fails ("SCX must immediately follow
its own cell's SC").
- Prepare-per-list instead of prepare-once-combined -> the CLIP/ALPHA
boundary batching test throws (index out of range).
Gates: Release build 0 warnings/0 errors. Hermetic lane (Lane!=Installed
Dat&...&Status!=KnownFailure) 6855/6855 passed. InstalledDat lane 249
passed / 10 failed — exactly the 4 pre-existing failures (#383 x2
LayoutImporter, TowerAscent KnownFailure, #458 Oh_doorway_still
KnownFailure) plus 6 NEW KnownFailure Facts
(AlphaFlushTranscript_*_MatchesRetailFrame2, one per capture) extending
this gate from PM/PC to AM/FL: the flush SITE+THRESHOLD sequence matches
the capture exactly for all six poses (including zero SortCellExit
drains in every capture, confirming the 0.75 valve is inert at these
scene complexities in both retail and this replay); the drained-COUNT-
per-list dimension diverges because this hermetic harness (matching the
existing PM/PC gate's own EmptyAlphaDepthWorldData design) carries no
live GfxObj/particle content, so every observed count reads (0,0)
against retail's real per-frame volume — both sequences quoted in full
per pose in the packet's new §10. Shader classes (VulkanShaderDescriptor
ContractTests/VulkanShaderManifestTests/RenderPackSpirvValidatorTests)
32/32 passed.

Record attempt 1's shader-source-hash contract conflict and permit only the deterministic manifest/paired vertex-SPIR-V closure needed by the required comment correction.
Start attempt 1/5 as an evidence-and-comment-only repair of a094bf2b7. Preserve behavior, assertions, shader/SPIR-V, register, package, sequential review, and no-landing-before-dual-PASS constraints.
Record a094bf2b7 as behaviorally retail-clean but unlanded because the binding evidence/prose contract failed. Preserve the sequential-review stop: the production lens did not run, no graphical gate ran, and G3/G4 remain unpassed.
Record the owner override after the required stop and bind the one-attempt repair to exact EnvCell pass membership, retail CLIP state, bounded source scratch, and production-path discriminators. Keep G3/G4 unpassed and the implementation unlanded pending dual review.
The 'empty plane under fog' frame the S4-c1 capture-pose self-gates produced
at frame 15 is the terrain seen from below by a falling player, not a draw
change: the camera probe holds playerCell=0xA9B4013F at (134.07,17.36) while
z drops 96 -> -20 m after materialization. The S3-state run had seated the
same request outdoors in 0xA9B40029 and stood. Placement is not the campaign's
domain; the gate pose is moved so the G3 frame is deterministic and the
original pose is kept in the issue as the reproduction. #462 recurrence on
the pre-S4 control build noted.

The two-list/router/flush core of 048d5b12f is exact at the bytes; the
failures are at the call sites (a data-driven row 5 turned into a throw;
detail-surface input hardcoded false while the drain applies detail),
the register (the structurally empty CLIP list is undeclared; AP-237's
example is wrong; AP-34 not retired by convention), the first-for-list
quantifier, the all-KnownFailure gate, and the skipped C4 that turns out
to be bounded.

Written for a fresh session on another account: read order, exact tips and
worktrees, what S1-S4-c1 landed with their proof, how to find the state of
the chunk 2 implementer dispatched this morning, the #464 attribution plan
(RenderDoc pixel history on the scripted artifact frame - the lead's own
job once ACE is up), the Holtburg doorway frame read, tooling gotchas, and a
paste-prompt.

The 2026-09-03 session landed S4 chunk 1 at 766f9e749 but ran out of
credits before writing the ledger row: round-2 lens verdicts, the landing
gates, the two capture-pose self-gates whose Holtburg doorway frame came
up as an empty plane under fog, the lead's read of that frame (the client
seated the player in the house-interior cell at the doorway threshold, so
the frame roots indoors with the eye outside), the crashed pre-S4 control,
and the S4-c2 dispatch that died with no commit.

S4-c1 per docs/research/2026-09-01-overhaul/s4-depth-alpha-packet.md §6.
S3 chunk 2 already landed the persistent portalsDrawnCount latch, the
gated clear, the exit-seal counting, and the look-in isolation — this
chunk covers only what §1/§2 of the packet name as still owed: C0-C3.
C0 — far-punch depth constant (R1: DrawPortalPolyInternal @0x0059bc90's
tail). portal_depth.vert's punch branch carried the decimal 0.99999988,
which reinterprets as bits 0x3F7FFFFE — fifteen ULPs FARTHER from the
camera than retail's real constant, bits 0x3F7FFFEF. Now writes
`uintBitsToFloat(0x3F7FFFEFu)` so the exact bits survive the GLSL/SPIR-V
compiler instead of trusting a decimal literal to round-trip unchanged.
Recompiled via tools/compile-shaders.ps1 (glslc 1.4.350.0 backend
recorded, managed shaderc path used); portal_depth.vert.spv's SHA-256
re-pinned in VulkanShaderManifestTests
(51c60d0924d62c61548efcf5f9e7672a121b1b68ca0a06755e32f1a4d73a8acf,
was 4ac1c452e7ac0d08a32f67fb03f21229af2d1605baa81f407240a3626251dfd7).
T1 (new Fact PortalDepthVert_FarPunchConstant_MatchesRetailExactBits in
VulkanShaderManifestTests.cs): a SOURCE pin — reads portal_depth.vert's
punch line and reinterprets whatever literal it carries (uintBitsToFloat
hex or a plain decimal) as raw bits, asserts == 0x3F7FFFEF. Verified
against the PRE-CHANGE source by hand-reverting the line to
`clipPos.z = clipPos.w * 0.99999988;` and re-running just this test:
Assert.Equal() Failure: Values differ
Expected: 1065353199
Actual: 1065353214
(1065353199 = 0x3F7FFFEF, 1065353214 = 0x3F7FFFFE). Line restored and
the test re-confirmed green afterward. MUTATION: any other literal fails
the same way.
C1 — the ±12 local-input reject (R2: 0x59BCD6-0x59BD28 then
0x59BD40-0x59BD66). The Ghidra arbitration table in
oh1-depth-lifecycle.md governs over the pseudo-C's own nested-if reading
of the four x87 FCOM results (BinaryNinja's `test ah, 0x44` condition
synthesis is FPU-flag-ambiguous and reads backward at face value — see
feedback_bn_decomp_field_names.md on decompiler flag mush as an artifact
class, not semantics): the table's row says "whole poly on any
local-input x/y == +/-12 boundary is rejected before count/clip" — taken
as written, not re-derived from the pseudo-C's literal branch nesting.
Ported as one shared predicate,
WalkVisibilityMath.IsRejectedByPortalPolygonBoundaryGuard(ReadOnlySpan
<Vector3>): true iff any vertex's X or Y is exactly +12f/-12f (retail
tests LOCAL x/y before xformStart, the world transform). Wired at BOTH
producers that own the LOCAL polygon before it leaves cell/building
space:
- WalkFrameDriver.OnPunchGeometry (the walk's punch-event producer,
IWalkEventSink.OnPunchGeometry) — checked on the building-local
WalkPolygon.Vertices before TransformToWorld; a hit returns before
MarkIfGrown/any event append (retail's reject -> transform -> clip
-> count order).
- RetailPViewPassExecutor.DrawPortalDepthWrite (the exit-seal
enumeration behind DrawExitPortalMask, the sole caller) — checked on
cell.PortalPolygons[index]'s local vertices before the
Vector3.Transform loop; a hit `continue`s with no `submitted++`.
T2 (three layers):
1. WalkVisibilityMathTests.cs — direct unit tests of the predicate:
Boundary_guard_rejects_a_polygon_with_one_vertex_exactly_on_plus_minus_12
(Theory, x/y == +-12 each), Boundary_guard_admits_a_polygon_whose_
nearest_vertex_is_just_inside_12 (Theory, x/y == +-11.999),
Boundary_guard_rejects_the_whole_polygon_even_when_only_one_of_
several_vertices_hits_it, Boundary_guard_ignores_the_vertical_z_
component, Boundary_guard_admits_the_empty_polygon.
2. WalkFrameDriverTests.OnPunchGeometry_RejectsWholePolygonOnExact
PlusMinus12LocalVertex_ButPunchesJustInside — functional: feeds
OnPunchGeometry a polygon with a vertex at x=12 (no PunchFan/no
"PUNCH:" log line) then one at x=11.999 (punches normally,
leaf.Punches has exactly one entry, log has exactly one "PUNCH:3@v0").
3. RetailPViewPassExecutorTests.DrawPortalDepthWrite_RejectsDegenerate
LocalPolygons_BeforeTransformOrSubmission — a real functional test of
DrawPortalDepthWrite needs a live PortalDepthMaskRenderer the suite
has no fake for, so this is a compiled-call-graph pin (this file's
established pattern for exactly this situation): the guard call
precedes both the Vector3.Transform loop and
PortalDepthMaskRenderer.DrawDepthFan by IL offset, gated by a
conditional branch immediately after it.
MUTATION texts, all verified live during this session then reverted:

ENABLED with a zero-alpha SRCALPHA/INVSRCALPHA blend). acdream's
PortalDepthMaskRenderer.Rhi.cs:92,100 sets ColorWrite=false alongside
Blend=None; portal_depth.frag writes no color output at all. Provably
pixel-identical (retail's blend collapses to dst'=dst when srcAlpha is
fixed at 0, for any RGB) and the write mask is the SAFER mechanism going
forward (structurally blocks any future accidental color write,
independent of an authored zero-alpha invariant). Added register row
AD-119 to docs/architecture/retail-divergence-register.md (the next free
id after AD-118), citing DrawPortalPolyInternal @0x0059bc90 and
PortalDepthMaskRenderer.Rhi.cs; section 2's active-row count and running
header note updated (90 -> 91).
C3 — the truth table + cross-frame latch tests. The (root kind,
draw_landscape, outside-view count, previous count) table's cells are
mostly already covered by S3 chunk 2's own tests — this chunk adds only
the genuinely missing rows/cases, and leaves every existing test
untouched:
Pre-existing coverage (named, not reproduced):
- interior, ov==0, prior==0 ->
RunFrame_InteriorFloodWithNoExitView_SkipsLandscapeAndNeverFlushesClearsOrSeals
- interior, ov>0, prior==0 ->
RunFrame_InteriorFloodWithExitView_FreshDriverSkipsTheGatedClearThenDrawsSealsAndFloodCells
and OnInteriorFloodDrawTurn_FirstOvFrameSkipsClear_SecondFrameArmedByFirstsSealsClears
(its own frame 1)
- interior, ov>0, prior>0 (T4's "frame 1 seals N>0 -> frame 2
clears" half) ->
OnInteriorFloodDrawTurn_FirstOvFrameSkipsClear_SecondFrameArmedByFirstsSealsClears
(its own frame 2)
- T4's "frame 1 seals 0 -> frame 2 does not clear" half (repeated
across three consecutive ov>0 frames, subsuming the two-frame
case) -> OnInteriorFloodDrawTurn_FloodWithNoExitPortal_NeverClearsAcrossFrames
- one look-in isolated from the root latch ->
LookInDrawCells_NeitherArmsNorConsumesThePortalsDrawnCounter
No further T4 test was added — the two existing facts above already
prove both halves of the two-consecutive-frames latch case exactly.
New rows added this chunk:
- WalkFrame_OutdoorRoot_NeverFiresTheInteriorClearSealMachinery: root
kind == OUTDOOR. RetailFrameWalk.WalkFrame's outdoor branch
((cameraCellId & 0xFFFF) < 0x100) calls DrawLandscape directly and
never calls DrawInside/OnInteriorFloodDrawTurn at all, so the whole
LFLUSH/stamp/CLEAR/SEALS mechanism structurally cannot fire —
driven end-to-end through RunFrame with an outdoor cameraCellId,
asserting SKY present, LFLUSH/CLEAR/SEALS absent, counter stays 0.
MUTATION (verified, then reverted): added a stray
`sink.OnInteriorFloodDrawTurn([], 1);` call to WalkFrame's outdoor
branch:
Assert.DoesNotContain() Failure: Item found in collection
↓ (pos 1)
Collection: ["SKY", "LFLUSH", "SEALS"]
Found: "LFLUSH"
- OnInteriorFloodDrawTurn_OvZeroAfterAPriorArmedCounter_LeavesTheLatch
CompletelyUntouched: interior, ov==0 immediately after an EARLIER
ov>0 frame armed the counter — proves the counter is left EXACTLY
as an earlier frame left it (not merely "not cleared this frame"),
since S3 §8.1 R3 gates the ENTIRE outside_view.view_count>0 block,
including the read-then-zero decision itself, on ov>0.
MUTATION (verified, then reverted): moved
`int armed = PortalsDrawnCount; PortalsDrawnCount = 0;` out of the
`if (outsideViewCount > 0)` gate in
WalkFrameDriver.OnInteriorFloodDrawTurn (unconditional
read-then-zero every call):
Assert.Equal() Failure: Values differ
Expected: 1
Actual: 0
(every OTHER WalkFrameDriverTests fact stayed green under this same
mutation — this new test is the only one that catches it).
- MultipleLookIns_WithinOneFrameAndAcrossFrames_NeverTouchTheRootLatch
(T5): extends the single-look-in fact to TWO look-ins in one frame
then a THIRD in a later frame. MUTATION (verified, then reverted):
a `_mutationLookInCalls` counter in HandleDrawCellsTurn's
LookInStatic branch that resets PortalsDrawnCount on the SECOND
look-in call:
Assert.Equal() Failure: Values differ
Expected: 1
Actual: 0
— while LookInDrawCells_NeitherArmsNorConsumesThePortalsDrawnCounter
(one look-in only) stayed green under the identical mutation,
confirming this test's incremental value over the existing single-
look-in fact.

Sixteen DrawPortalPolyInternal attempts per frame, vertex-identical to
acdream's sixteen collect-time punches; twelve lie entirely on the local
y=12 plane and are rejected by the ±12 guard in both clients, so the hall
building's doorways are never punched in either.

Retail admits exactly acdream's cells and building-portal groups in the
same order; its alpha-depth frame punches each portal polygon to far depth
right before that group's cells and seals the exit views last. The
capture becomes S4-c1's fifth transcript pose.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Root 0xF4180114 with seven outside views; retail admits the same seven
hall building-portal groups in the same order as acdream, yet shows the
solid far face above the arch. The fifth transcript pose for S4.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The frame is saved as logs/464-owner-tilted-frame.walk.txt. Narrowed to
the building shell versus interior-cell order/clip at the stairwell's open
face in the outside pass (S4), with a possible building-portal admission
component only the cathedral-stair-arch retail capture can settle.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The automation cannot tilt the camera, so the owner's screenshot stays the
record of the frame; the transcript shows the interior root flood of the
three stacked stair cells with six outside views and fifteen building-
portal groups including the hall cells. The retail capture at this pose
decides depth (S4) versus admission.

Owner client with both probes: root 0xF4180114, eye (39.89,17.25,182.36),
sweep uncontacted; the hall's interior shows above the bottom arch where
retail shows the solid far face, which the DAT gives as five exit portals.
The retail capture cathedral-stair-arch is requested as the fix oracle.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The eye is legitimate (retail's sweep passes the same opening); the defect
is the draw of the stairwell cells seen back through the building's
exterior portals. Matrix row invariant re-worded; the one retail capture
to request is the oh-capture walk + alphadepth at exactly this eye.

Read-only decomp + real-DAT replay: eleven sweep/root differences, each
unreachable at the pose or more constrained than retail; the replay seats
the pivot in 0xF4180114, stops the boom on its east pier at y=16.448, and
the walk from that root floods 114/113/112 with seven exit views. The
owner's probe launch line now also sets ACDREAM_PROBE_FACILITY_STAIRS.

Drafted from the five alphadepth captures (10,556 AM lines, every clip=0;
FL by return address 13,705 / 309 / 18 / 23) and the OH1 alpha-list
contract. Dispatch waits for S4-c1 to land.

Four probe-on self-gate rounds (run/zoom/tilt/mid) with the camera cell,
root and eye logged every frame: sweep ok, eye in root, no fallback, in
every frame. The DAT shows 0xF4180113/0xF4180114 are one stairwell split
horizontally; the zoomed-out eye stops 0.31 m in front of 0x114's
nine-vertex EXIT portal. Owner asked for one probe-on reproduction.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The held-forward route captured the owner's running symptom: the first frame
after the press has the chase camera above and outside the stairwell, the
next is clean. Same defect as the zoom-out. The runs also showed the
character running in place at one corridor spot for 5+ s (#467, movement,
outside the campaign).

The round-0 retail and production lenses both found the guard's
quantifier inverted (the lead's paraphrase); the production lens's DAT
scan found 2,163 exit polygons lying entirely on a ±12 plane, which makes
the guard the likely mechanism behind retail's never-sealed seam family.
The PM/PC transcript comparison becomes the chunk's own gate.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The S4-c1 retail lens caught the lead's paraphrase inverting retail's
predicate (any vertex on any plane vs every vertex on the same plane);
the contract and T2 now state the decomp's four per-plane predicates.

Owner decision 2026-09-03: an improvement on retail, deferred until G4
passes; retail mode off; registered when built.
