+## Batch AC graphical-host and lifetime source-freeze replacement
+
+Batch AC converts all nine approved `GameWindowHostBoundaryTests` source
+readers. No product source changes and no test is removed.
+
+Startup now follows the compiled settings snapshot, frame-pacing, native
+window, callback-target, callback-binding, attachment, and frame-loop edges.
+The callback delegate targets retain their exact load/update/render/closing/
+focus/resize order without treating local names, comments, or nested argument
+spelling as behavior. `OnLoad` phase ordering is recovered from its compiled
+delegate targets, while frame-root and session-player completion checks follow
+their typed construction, binding, attachment, publication, and transfer
+edges.
+
+The remaining owner checks reflect the one `WorldEnvironmentController` and
+`RuntimeSettingsController`, reject their displaced window mirrors, and
+follow environment routing, settings startup/runtime binding, terrain-atlas
+acquisition, input-action attachment, and framebuffer-resize publication
+through the built methods. Focus, update, render, close, and dispose are
+verified as narrow handoffs. In particular, the render check uses semantic IL
+execution order—window size, immutable input construction, then graph render—
+rather than the misleading lexical order of a nested source expression.
+
+Shutdown now uses reflected root types, field stores, built call order, and
+the compiled manifest's stage/operation labels. It preserves the twenty-stage
+dependency order, plugin transfer before startup, ingress cleanup ordering,
+Runtime/UI/resource release boundaries, `TryComplete` before native-window
+release, and the final `_window` clear after the shared shutdown funnel. A
+label such as `input context` may legitimately identify both an operation and
+its stage; the replacement therefore verifies dependency order instead of
+mistaking duplicate human-readable labels for duplicate ownership.
+
+The old checks for HostInputCamera local `if` spelling are retired rather than
+translated. `HostInputCameraCompositionTests` already exercise the complete
+production acquisition and every fault boundary; the names and arrangement
+of compiler locals are not part of the host contract. All valuable ownership,
+ordering, and cleanup rationale remains in the compiled guards above.

+Verification:
+
+- all nine focused graphical-host/lifetime 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 39/55 to
+  32/46. The remaining 46 reconcile to the 22 approved retained
+  policies/contracts and 24 staged replacements.
