 # GameWindow Slice 1 — selection and interaction ownership
 
-**Status:** Approved for execution 2026-07-21.
+**Status:** COMPLETE — landed 2026-07-21.
 **Parent program:** [`docs/architecture/code-structure.md`](../architecture/code-structure.md), Slice 1.
 **Baseline:** `cf50ee3d`; `GameWindow.cs` is 15,723 lines before this slice.
 **Behavior rule:** Existing retail behavior moves unchanged. Any defect found by
 the extraction audit is fixed in a separately identified commit before the
 mechanical cutover.
 
+## Landing record
+
+- Plan/oracle: `c2713837`.
+- Exact-incarnation lifetime hardening: `047a4c83`.
+- Retail pending keyboard-pickup presentation: `52dbb574`.
+- Read-only query extraction: `e74f2ca9`.
+- Stateful interaction owner: `fa8d5232`.
+- `GameWindow` cutover: `d2bb5af4`.
+- Three-review correction pass: `5acc3f01`.
+
+The correction pass unified retail's one-inventory-request-at-a-time owner
+across every mutation surface, separated optimistic/rollback/authoritative
+placement notices, made response completion atomic and reentrancy-safe, and
+bound pending work to exact object identities and placement tokens.
+
+Final metrics: `GameWindow.cs` 15,723 → 14,912 lines and 205 → 191 methods;
+fields remained 278. Release build passed, the focused selection/inventory
+gate passed, the full suite passed 6,558 tests with five intentional skips,
+and the retail-conformance, architecture/integration, and adversarial reviews
+all finished with no actionable findings.
+
 ## 1. Outcome
 
 `GameWindow` stops owning world selection and selection-driven interaction.
