+## Batch AB render-leaf and frame-handoff source-freeze replacement
+
+Batch AB converts all nine approved `GameWindowRenderLeafCompositionTests`
+source readers. No product source changes and no test is removed.
+
+Private presentation, resource preparation, world/private/diagnostic routing,
+GPU measurement, and immutable outcome construction now follow compiled typed
+calls in their production order. The portal-tunnel check follows the compiled
+session transfer/bind/publication path, both local teleport factory targets,
+the session-before-frame phase references in `OnLoad`, and the exact frame-root
+borrower construction order. `OnRender` now proves its single
+`GameFrameGraphSlot.Render` handoff and absence of the five displaced leaf
+field reads directly from the built method.
+
+The broad legacy-owner blacklist is narrowed to what it actually protects:
+reflected `GameWindow` fields and methods reject the displaced owners, while
+compiled composition metadata positively locates paperdoll, frame-resource,
+weather, private-presentation, orchestrator, frame-pacing, and mouse-capture
+ownership behind their focused types. Shutdown ordering uses the compiled
+operation/stage labels. Terrain diagnostics are constructed with the scene
+executor but not driven directly by the frame root.
+
+The optional paperdoll contract is stronger than the old source-expression
+match: compiled branch destinations prove that either a missing viewport or a
+missing inventory frame jumps past `PaperdollFramePresenter` construction.
+`CompiledCallGraph` gained a reusable branch-target reader for this kind of
+optional-dependency guard.

+Verification:
+
+- all nine focused render-leaf methods pass;
+- the complete locked Release build covers all 44 projects with zero warnings
+  and zero errors;
+- the no-retry complete hermetic Release gate remains 14,346/14,346 with zero
+  skips or failures across all 12 test assemblies; and
+- the regenerated 1,254-file inventory parses every file, remains at 11,414
+  attributed methods, and reduces direct/total source readers from 41/64 to
+  39/55. The remaining 55 reconcile to the 22 approved retained
+  policies/contracts and 33 staged replacements.
