 This document records verified risks, the production controls that address them, and the next evidence to collect. It is intentionally operational: a passing build alone is not proof that the browser application is production-ready.
 
+## 2026-07-16: high-cardinality address cache lifecycle
+
+The monitor list previously retained every manually resolved coordinate for 24 hours, and track replay inherited the global five-minute cache for every paused point. Long-running dispatch sessions could therefore accumulate address payloads across pages and arbitrary playback coordinates even after their components disappeared.
+
+Both query families now use zero inactive-cache retention: the visible list row or current paused track point keeps its address while mounted, but switching monitor mode, selecting another point, or leaving the route immediately releases the previous browser entry. This does not cause repeated AMap quota consumption because the authenticated server adapter independently owns the one-hour, 4,096-entry LRU cache and collapses concurrent misses. Component tests prove list addresses reach zero after returning to map mode, track address churn retains only one active key, and route unmount leaves no track address entry.

 ## 2026-07-16: complete release-asset compatibility gate
 
 Release `web-release-smoke-20260716015150` installs `deploy/verify-web-release.sh` as a production release gate. It verifies the exact root document, runtime configuration object, every original asset in the current `.release-assets` manifest and every original asset in the immediately previous manifest. Asset responses are compared byte-for-byte with the active release files; HTTP 200 with an SPA HTML fallback therefore fails instead of masking a missing lazy route chunk.
