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.
The retail frame walk's world model now materializes from production
landblock-build owners through the legal IDatReaderWriter seam, with
zero frame wiring (FW3.2 roots the frame):
- WalkCellFactory: WalkCell built in the SAME pass as LoadedCell
(EnvCellLandblockBuild.BuildVisibilityCell) from the raw portal
Flags/polygons/planes/stab lists already parsed there; stored as
LoadedCell.Walk, committed atomically with the cell. The
fixture-pinned decodes (inverse-0x2 portal side, 0xFFFF->0xFFFFFFFF
exit widening) live here.
- WalkBuildingFactory + WalkBuildingRegistry: the production
WalkBuilding build (drawing BSP with PORT nodes, degrade ladder,
portal sides/stab lists, sort center, model frame) from the SAME
LandBlockInfo the streaming build already fetches, under the
factory's existing DAT lock - closing the gap where BuildingLoader
drops every walk field at load.
- WalkLandscapeAssembler: the retail 51x51 viewer-centred grid
(mid_radius 25) fed incrementally from landblock publish/retire;
per-block z-slab (heightTable[max]+200 / [min]-1) computed
worker-side in LandblockBuildFactory from the heights already in
hand. O(1) SetViewer on same-block frames.
- WalkProductionFrameContext: the walk's frame contexts over
CellVisibility + WalkBuildingRegistry with a generic
inverse-view-projection ray caster (rays feed cross products only -
scale-free) and the znear=0.1 CY plane.
- Publication: LandblockRenderPublisher owns both walk registries,
publishing in the same AdvanceCompleteOne step as BuildingRegistry
and retiring in RemoveBuildingRegistry - same commit, same
retirement, no new ticket stage.
Conformance: ALL TEN oracle fixtures replay identically through the
PRODUCTION builders (WalkProductionWorldConformanceTests) - same
signatures as the test adapter, first run. Known gap documented for
FW3.2: far-tier landblocks carry no EnvCell transaction, so their
z-slab never reaches the assembler.
Suites: full Release build 0 warnings; Walk lane 186/1 skip;
hermetic 6,738/0 (+24); RuntimeDatAccessArchitectureTests green.
