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 per-building join diagnostic PASSES (001a/0022 portal tables lead
exactly to the traced a9b4016x punch cells; every BSP PortalRef indexes
validly), and the eight-arm gate-decode sweep proves NO plane-sign x
side-flag combination reproduces retail. Together they pin the missing
mechanism: CEnvCell::GetVisible gates punches by the LOADED interior
cell set around the player - retail punched only the two buildings
nearest the player cell; the replay loads every interior so geometry
alone over-punches. Next port piece: the interior load radius (the
landcell stab-list pull). Both diagnostics stay in the suite (the sweep
Skip-parked with the verdict).
