 are flaky. The inventory run at `6faeb4a1` parsed all 1,256 tracked C# test

+## Batch I source-text replacement map
+
+The refreshed inventory finds 63 attributed methods that directly read `.cs`
+source text. Reconciliation with historical T-012 assigns every method to one
+of three dispositions:
+
+| Disposition | Methods | Owning test files |
+|---|---:|---|
+| Campaign-era implementation-shape freeze; replace in stages | 46 | `ContentEffectsAudioCompositionTests`, `FrameRootCompositionTests`, `HostInputCameraCompositionTests`, `InteractionRetainedUiCompositionTests`, `LivePresentationCompositionTests`, `SessionPlayerCompositionTests`, `WorldRenderCompositionTests`, `GameWindowLiveSessionOwnershipTests`, `GameWindowRenderLeafCompositionTests`, `GameWindowSlice8BoundaryTests`, `ResourceCleanupGroupTests`, `RetailPViewPassExecutorTests`, `WorldRenderFrameBuilderTests`, `WorldSceneRendererTests`, `LandblockBuildOriginTests`, `LandblockPhysicsPublisherTests`, `LandblockRenderPublisherTests`, `GameWindowLiveEntityCompositionTests`, `UpdateFrameOrchestratorTests` |
+| Whole-tree architecture policy; retain, then make syntax/metadata-aware | 12 | `LinuxPlatformBoundaryTests`, `RenderSceneArchitectureTests`, `RuntimePhysicsOwnershipTests`, `RuntimeEntityOwnershipTests` |
+| Source/project/artifact text is the actual cross-artifact contract; retain | 5 | `ParticleBindlessInstanceTests`, `PerformanceToolsTests`, `LauncherProjectBoundaryTests` |
+
+The 46 implementation-shape facts were useful during mechanical ownership
+cutovers, but are not durable behavioral evidence. They pin constructor
+spellings, local names, exact call fragments, or statement order; comments can
+satisfy many of their `Contains` checks, while a harmless equivalent refactor
+can fail them. Their intent is often valuable—single ownership, ordering,
+handoff, teardown, or absence of a parallel path—so wholesale deletion would
+discard real notes and weaken some boundaries.
+
+R3 therefore uses this replacement rule for those 46 facts:
+
+1. preserve the ownership/order rationale in the architecture document or this
+   ledger;
+2. identify an existing behavioral, lifetime-ledger, project-reference, or
+   reflection/Roslyn guard that proves the same claim;
+3. add the semantic replacement first when none exists; and
+4. remove the literal source freeze in the same small batch.
+
+The 12 whole-tree rules remain valuable even before conversion: they ban
+platform calls outside owners, enforce assembly/namespace containment, and
+prevent duplicate Runtime entity/physics authorities. The five cross-artifact
+tests compare two independently consumed artifacts (for example CPU/shader
+constants, launcher project/workflow/markup, and CLI route tooling); reading
+text is appropriate there.
+
+No source-freeze fact is removed in this classification batch. The 46 staged
+facts are an ambiguous architecture decision and will be presented for user
+approval in behavior-owner groups rather than deleted from a numeric heuristic.
