Publish the exact completed walk landscape set as the typed retained particle-view product. Apply retail CLandCell membership versus constant-true non-null CEnvCell eligibility while preserving the x87 distance and AP-116 behavior.
Delete the null-root terrain visibility reconstruction and the dead drawable-cell point-light feedback chain. Retire AP-117, correct AP-85 and AD-21, and keep directional shadows, building degrade, AP-232, probes, RHI, shaders, and DAT outside this chunk.
Automated return: Release 0 warnings/0 errors; Core VFX 111/111; App particle/frame/renderer/terrain 146/146; warmed production allocation 1/1 at 0 B. First official hermetic artifact s5-c1-hermetic-20260904 is preserved at 16759/16760 with only the stale 162-row assertion; after the bounded 161 correction, exact pin 1/1 and fresh s5-c1-hermetic-corrected-20260904 16760/16760. InstalledDat 385 pass, 10 documented failures, 1 documented skip, no new identity.

Chunk H of Campaign OVERHAUL v2's S3 walk-ownership program
(docs/research/2026-09-01-overhaul/s3-walk-ownership-map.md §10.6), landing
the three post-hoc three-lens findings on S3 chunk 4 round 2. Pure dead-state
deletion, comment truth, one test deletion, one stronger pin — no admission,
order, or behavior change; no new flag or probe; no register row (AD-17's
correction is the lead's own, already on the campaign branch).
H1 — ClipPlaneSet.cs: deleted ScissorNdcAabb (no production reader — only
AppendOutsideSlice consumes ClipPlaneSet, and it reads only
IsNothingVisible/Count/PlaneArray) and renamed UseScissorFallback ->
IsPlaneOverflow with a doc stating the true consumer contract: Count==0
overflow means the region draws UNCLIPPED via the no-clip slot, never a
scissor box. Rewrote the file header's convexity-rule and Count==0-states
sections to the two states that exist (Empty / overflow) instead of three,
and simplified the private Scissor(...) AABB-computing helpers into a
parameterless Overflow() factory since nothing reads the AABB any more.
ClipPlaneSetTests.cs: renamed every UseScissorFallback reference, deleted
the AABB assertions (From_MultiplePolygons's four ScissorNdcAabb.X/Y/Z/W
checks, Empty_StaticProperty_DrawsNothing's degenerate-box check,
ScissorFallback_IsNotNothingVisible's bounds check) that pinned the deleted
consumer contract.
H2 — TerrainModernRenderer.cs: deleted Draw's clipPlanes/ndcClipAabb
parameters (grep: TerrainModernRenderer.Draw has exactly one production
caller, WorldScenePassExecutor.DrawFlatTerrain, and it never passed
either), which made CollectVisibleCells's own clipPlanes/ndcClipAabb/
viewProjection parameters and the IsAabbVisibleThroughClipRegion +
IsAabbOutsideHomogeneousPlane helper pair they fed entirely dead — deleted
along with the stale "Retail publishes landcell in_view from the clipped
landscape view" comment; CollectVisibleCells is frustum-only now, matching
DrawLandCells's own "retail never view-clips terrain" doc. Deleted the
terrainUploadCount computation at RetailPViewRenderer.cs (the
DrawInside/DrawLandscapeDynamicsPhase caller) and PrepareClipFrame's
GL-era reservation-count parameter end to end:
IWorldPassSurface.PrepareClipFrame(int), RhiWorldPassSurface's matching
body and its now-pointless "_ = terrainUploadCount" discard,
RetailPViewPassExecutor.PrepareClipFrame's pass-through, and
WorldScenePassExecutor.PrepareFlatWorldClip's hardcoded `1` argument —
PrepareClipFrame() takes nothing on every arm.
TerrainParticleCellVisibilityTests.cs: deleted the three tests that only
existed to pin the removed clip-plane/scissor mechanism
(RejectsCellsOutsideDoorwayClipPlanes, RejectsCellsOutsideDoorwayScissorAabb,
UnionsCellsFromEveryLandscapeSlice) and updated the two surviving frustum
tests to the new signature.
H3 — deleted tests/AcDream.App.Tests/Rendering/Issue130DoorwayStripTests.cs
outright. #130 was a background-color strip along a doorway's top edge from
a since-fixed under-inclusion in the CPU clip pipeline; its scissor half was
already retired at S3 chunk 4 fix round 2 (L7), and its surviving plane-gap
half exercised only PortalVisibilityBuilder.Build and
ClipFrameAssembler.Assemble, both confirmed zero-production-caller legacy
paths (grep) — the one production stage it actually touched,
ClipPlaneSet.From, is already pinned through the real producers
(BeginWalkFrame/ReassembleOutsideViewFromWalk) by the K6/L4 punch-fan
equivalence pin in ClipFrameLayoutTests, so nothing production-relevant lost
coverage.
H4 — comment truth pass:
- ClipFrameAssembler.cs: rewrote the file-header "renderer uses scissor for
passes that need that fallback" line and the TerrainClipMode summary's
"that path never produces Scissor" clause. Deleted the TerrainClipMode
enum's Scissor member — grepped every reader first
(WorldRenderDiagnostics.cs, WorldSceneDiagnosticsController.cs,
WorldSceneRendererTests.cs all only pass the value through to a string
Append or a mock parameter; WorldSceneRenderer.cs, the only writer, sets
only Planes (default) or Skip, never Scissor) — kept Planes/Skip for the
flat path and corrected Skip's stale doc ("No outside_view slice is
visible; skip landscape indoors", a leftover from the pre-round-2 walk
meaning) to what the flat path's own writer actually means now ("the
PView walk ran instead of the flat-world path this frame"). Corrected
ClipViewSlice's doc: the AABB is retained for WorldRenderDiagnostics only,
not for a scissor consumer.
- WorldPassSurface.cs: "Four concerns... the clip-frame publication, the
doorway scissor, gl_ClipDistance enablement, and retail's interior depth
clear" -> three concerns (the doorway scissor was retired at L2), with a
pointer to ClearInteriorDepth's own truthful doc. EnableClipDistances'
"all three world vertex shaders already write 1.0" -> only
portal_depth.vert writes gl_ClipDistance now (grep: sky.vert and
terrain_modern.vert/terrain_atmospheric.vert no longer declare it at all
— L3 deleted the block outright; portal_depth.vert still writes 1.0 past
its active clip count). RhiWorldPassSurface's class doc dropped "the
scissor is dynamic state on the borrowed encoder" (no producer left).
- RetailPViewPassExecutorTests.cs: DrawLandscapeDynamicsPhase_CallsDraw
WeatherOnceExactlyOnce's doc corrected "unconditionally" (false since K2)
to "conditional on WalkFrameDriver.WeatherTurnFired, see the L1 pin".
Added the switch-table scope note (matching L8's own note on
DrawWalkSky_RenderSkyCallSiteHasNoEnclosingBackwardBranch) to the K1 pin's
doc (DrawLandscapeDynamicsPhase_DrawWeatherOnceCallSiteHasNoEnclosing
BackwardBranch).
- RetailPViewRenderer.cs: the DrawWeatherOnce citation cited the callee
address (GameSky::Draw(sky,1) @0x00506ff0) where §10.1 cites the call
site (@0x00506396) — corrected to cite the call site with the callee
address alongside it.
H5 — MUTATION CHECK (mandatory, run against the production gate at
RetailPViewRenderer.DrawLandscapeDynamicsPhase):
Added DrawLandscapeDynamicsPhase_ExactlyOneBranchGuardsDrawWeatherOnce,
which widens the L1 pin's window to start at the
DrawUnattachedSceneParticles call (the last call before the whole gate)
and asserts EXACTLY ONE branch total in that window — the L1 pin's own
window (getter-call to draw-call) misses a conjoined gate's extra,
earlier condition because that condition's own brfalse lands BEFORE the
getter call's offset.
- Mutation 1 (the conjoined gate this pin exists to reject): changed the
gate to `if (clipAssembly.OutsideViewSlices.Length != 0 &&
walkDriver.WeatherTurnFired)`, built, ran the new pin — FAILED with:
Assert.Single() Failure: The collection contained 2 matching items
Expected: (predicate expression)
Collection: [CompiledBranch { Offset = 7, OpCode = brfalse.s, TargetOffset = 17 }, CompiledBranch { Offset = 24, OpCode = brfalse.s, TargetOffset = 42 }, CompiledBranch { Offset = 33, OpCode = brfalse.s, TargetOffset = 42 }]
Match indices: 1, 2
(offset 7 = the DrawUnattachedSceneParticles block's own guard, correctly
excluded since it precedes that call's offset; offsets 24 and 33 are the
conjoined gate's two brfalse's, both inside the widened window — exactly
the failure this pin exists to catch). Restored the single-flag gate;
rebuilt; the new pin and all 13 sibling tests in
RetailPViewPassExecutorTests pass again (14/14).
- Mutation M1 (the existing round-2 regression: restore the pre-fix gate
`if (clipAssembly.OutsideViewSlices.Length != 0)`), built, ran the full
suite — the L1 pin
(DrawLandscapeDynamicsPhase_GatesDrawWeatherOnceOnWalkDriverWeatherTurnFired)
still FAILS, as required, with:
Assert.Equal() Failure: Values differ
Expected: typeof(AcDream.App.Rendering.Walk.WalkFrameDriver)
Actual: typeof(AcDream.App.Rendering.ClipFrameAssembly)
(the new H5 pin does NOT fail under M1 — a single-flag gate still
produces exactly one branch in the widened window, which is correct:
catching "wrong condition source" is L1's job, catching "an extra
conjoined condition" is H5's). Restored the correct gate; rebuilt;
14/14 green again.
H6 grep sweep (extends §10.5's L6 sweep per the plan):
grep -rnE "ScissorNdcAabb|UseScissorFallback|TerrainClipMode\.Scissor|ndcClipAabb|terrainUploadCount" --include=*.cs --include=*.vert --include=*.frag src tests
-> empty (every mention, including in this commit's own explanatory
comments, was rephrased to avoid the literal deleted identifiers).
The base L6 sweep (SetTerrainClip|BeginDoorwayScissor|BindTerrainClip|
TerrainBytes|active scissor|TerrainClipMode\.Scissor|NdcScissorRect) is
also still empty.
Gates: dotnet build tests/AcDream.App.Tests -c Release -> 0 warnings / 0
errors. Hermetic lane -> 6825/6825 passed, 0 failed. InstalledDat lane
(ACDREAM_DAT_DIR set) -> 243 passed / 4 known failures (2x #383 layout
tests, TowerAscentReplayTests's TowerAscent KnownFailure,
WalkTraceConformanceTests.Oh_doorway_still_first_frame_diff #458
KnownFailure) / 1 skipped / 248 total — one fewer test than before H3, as
expected from Issue130DoorwayStripTests's deletion.

Resolve DAT-authored particle ranges from the hardware GfxObj, apply retail distance and completed-cell visibility gates, and preserve the exact finite/infinite off-view update semantics. This removes dense-world simulation work without shortening terrain, entity, fog, or streaming distance.
Publish doorway-clipped outdoor cells through a focused frame controller, retain effect cell identity for outdoor statics, reject hidden emitters before particle-slot scans, and offer an explicit opt-in Extended particle range.
Release build succeeds and all 5,857 tests pass with five intentional skips. Retail-conformance, architecture, and adversarial review cycles are clean; connected Aerlinthe visual/performance gate pending.
