+## #457 — Two App tests pass only in Release (IL-offset pins fail under Debug)
+
+**Status:** OPEN — found 2026-09-03 during the S3 chunk 3 re-review; pre-existing at `dffd7055` (before chunk 3), not a campaign regression.
+**Severity:** LOW (test-configuration gap; every gate runs Release, CI runs Release)
+**Component:** App tests — branch-offset pins
+
+**Symptom:** with the CI hermetic filter, `dotnet test tests/AcDream.App.Tests -c Debug`
+fails exactly two tests that pass in Release:
+`GameWindowRenderLeafCompositionTests.PaperdollComposition_SkipsEitherMissingOptionalUiSurface`
+("Filter not matched in collection" over `CompiledBranch` offsets) and
+`LiveEntityNetworkBranchRoutingTests+LiveEntityNetworkUpdateControllerForcePositionWiringTests.CommittedOrDeferredCellReturnsBeforeReachingTheGenericTail`.
+Both pin compiled-branch IL offsets that differ between Debug and Release codegen.
+
+**Fix direction:** make the two pins configuration-independent (assert on the
+branch's semantic target, not the IL offset) or tag them `Lane=Release` with a
+documented reason. Not urgent; do not chase individually per `docs/release-gate.md`.
