 - Layered decision model:
   - Engineering signoff: based on Windows real logs + simulated multi-platform three-cohort gates.
   - Release signoff: marked as `TODO` when real multi-device cohorts are missing and tracked in future test backlog.

+- Result:
+  - Windows single-platform gate: `PASS`
+  - Engineering signoff (no multi-device hardware): `PASS`
+  - Release signoff: `TODO` (pending real macOS/Android/iOS cohorts)
+- Core comparison (P50):
+  - `TTI`: `1509.40ms -> 1039.50ms`, improvement `31.13%`
+  - `TFS`: `2299.40ms -> 1679.50ms`, improvement `26.96%`

   - 工程签收：基于 Windows 真实日志 + 模拟多端三规模门禁。
   - 发布签收：若缺少真实多端 cohort，状态为 `TODO`，并写入未来待办待测事项。
