Verify source coordinates against an actual earlier materialization log. Record teleloc WXYZ ordering independently of the Position constructor; keep tutorial and combat coverage claims distinct.
Use existing 0125 and starter 8C04 research locations, independently of forthcoming fixes. Preserve the missing full starter pose as an explicit pre-launch task; no gate PASS inferred from selection.
Keep screenshot repair separate from the active #475 retirement chunk. Record independently verified source ordering, invalid first-resize PNG, provenance limits and required next proof; no production change or gate PASS.
Delete the callerless portal-BFS research graph and spent renderer probe families while retaining the production RetailFrameWalk path, terrain diagnostics, membership invariant, and walk transcript.
Mutation evidence (all restored):
1. Restored PortalVisibilityBuilder type -> AppAssembly_ContainsNoSupersededPortalGraphTypes first failed Assert.Empty with AcDream.App.Rendering.PortalVisibilityBuilder.
2. Restored ACDREAM_PROBE_FACILITY_STAIRS -> ProductionSource_ContainsNoDeletedRendererProbe_AndRetainsWalkTranscriptProof first failed Assert.Empty on RenderingDiagnostics.cs.
3. Added a second RetailFrameWalk field -> WalkFrameOwners_AreUnique first failed Assert.Single with _frameWalk and _mutatedSecondFrameWalk.
4. Added OrderBy to OrderedStream -> OrderedWalkStream_HasNoCrossStreamReorder first failed Assert.DoesNotContain on OrderBy(.
5. Added IDatReaderWriter parameter -> FrameTimeWalkOwners_HaveNoRawDatDependency first failed Assert.Empty on RetailFrameWalk.MutatedRawDatParameter.
Keep both atmospheric vertex receivers on retail's exact authored, unnormalized uLights direction in every shadow-gate state while preserving the selected celestial direction for fragment shadow projection and volumetrics. Regenerate the affected SPIR-V and amend IA-24.
Proof adds committed-SPIR-V dataflow checks, parent plain/pipeline source pins, and a real Vulkan mesh+terrain pixel witness owned by Lane=Vulkan.
Mutation first failures (all restored):
1. Restoring the mesh shadow/celestial branch failed CommittedProductionAtmosphericReceivers_KeepAuthoredLightAcrossShadowGate at line 27: expected Pixel 128/128/128/255, actual 0/0/0/255.
2. Restoring the terrain shadow/celestial branch failed the same witness at line 28: expected Pixel 128/128/128/255, actual 0/0/0/255.
3. Normalizing the authored mesh direction failed AssertAuthoredHalfIntensity at line 277: expected 126..129, actual 255.
4. Removing atmospheric_volumetric.frag's celestial xyz use failed ProductionShadowAndVolumetricModules_StillNormalizeTheCelestialProjectionDirection at line 61: Assert.Single found no matching member-5 access.
5. Restoring IA-24's old celestial-base-light claim failed BuiltInAndDeclaredShadowGraphsUseTheSameTypedPriorVisibilitySelector at line 1482: the authored unnormalized uLights sole-base-light assertion was absent.
Tag the production offscreen witness as Lane=Vulkan, exclude capability-owned tests from the portable Release filter, and give lavapipe an explicit trait-only invocation after the portable Vulkan contracts.
Document the lane and pin witness, portable-filter, and workflow ownership without initializing Vulkan.
Mutations performed and restored:
1. Removed the witness trait: VulkanLaneOwnershipContractTests first failed Assert.Matches because the Lane=Vulkan/Fact/method pattern was absent.
2. Removed Lane!=Vulkan from the default filter: the contract first failed Assert.Contains, not found Lane!=Vulkan.
3. Weakened the dedicated invocation to Lane!=Vulkan: the contract first failed Assert.Contains, not found --filter Lane=Vulkan in the hardware step.
4. Narrowed the dedicated invocation with FullyQualifiedName: the contract first failed Assert.DoesNotContain because FullyQualifiedName was present at position 231.
Record retail/behavior review pass 1/10: renderer behavior is correct, but the physical-device witness cannot live in the portable Release lane. Bind fix round 1 to an explicit Vulkan lane owned by the existing lavapipe job and current-machine proof.
Bind S5 packet section 27 for issue 470. The contract preserves the shared absolute transform index while making every live per-submission sidecar local, requires a nonzero-prefix production recording and offscreen pixel witness, and keeps receiver selection plus issue 469 out of scope.
Add paired depth-write variants for all five blended SetSurface families in ordinary and atmospheric Wb pipeline sets at both sample counts and in EnvCell. Select them only from the carried AlphaTestEnabled state, retain pure-Clip and Translucent override behavior, and cover disposal plus partial-construction rollback.
Correct the three stale depth oracles and the AP register count/temporary AP-232 overclaim.
Required restored mutations and first discriminating failures:
1. Wb StraightAlpha+Clip collapsed to depth-off: WalkStaticStreamPopulatorTests.ImmediateBuildingDetail_UsesExactResolvedSetSurfaceState failed at line 1278; expected wb-mesh-alpha-depth-write-1x, binds were wb-mesh-alpha-1x.
2. EnvCell raw Additive+Clip collapsed to depth-off: EnvCellAlphaDrawSourceTests.DetailOn_EveryEnvCellFamilyDrawsOnceInPlaceWithAuthoredOpacity failed at line 132; expected envcell-raw-additive-depth-write, actual envcell-raw-additive.
3. EnvCell non-Clip raw Additive forced depth-on: the same production transcript failed at line 132; first row expected envcell-raw-additive, actual envcell-raw-additive-depth-write.
4. Late Translucent|Clip override forced alpha-test/depth-on: the same production transcript failed at line 132; expected envcell-alpha, actual envcell-alpha-depth-write.
Resolve exact SetSurface blend, alpha-test, and fog state once during extraction and preserve it through recipe-10 prepared payloads, Wb/EnvCell command data, Vulkan pipelines, push constants, and both ordinary/atmospheric one-pass shaders. Preserve AP-240 Wb pure-Clip immediate opaque/A2C while EnvCell uses retail premultiplied Clip; detail-off routing remains unchanged. Correct AP-232 and register the remaining detail-off state divergence.
