-### BUG-07 — Trip replay on portal sometimes does nothing
-- **Status**: `OPEN`
-- **Severity**: Low/Medium
-- **Area**: `static/js/history.js`, server `/api/v1/portal/trip/<id>`
-- **Phase**: Phase 26
-- **Symptom**: Clicking a trip to replay intermittently does nothing — no route, no error.
-- **Root cause**: Not isolated. Possible API/DB race, DB lock, map readiness.
-- **Fix scope**: Add diagnostics. Add explicit error state.
-- **Acceptance**: Replay reliable; failures show visible error.

+- **Status**: `CLOSED` 2026-08-11
+- **Commit**: `fa93384`
+- **Fix**: Full rewrite of `static/js/history.js`: unified AbortController cancels fetch
+  + all downstream rendering on trip switch; 300ms debounce prevents double-tap stacking;
+  loading spinner on map + `.table-active` row highlight give clear feedback; geocode
+  preload starts immediately before map rendering so cache is warm for the scrubber;
+  `signal.aborted` guards after every async step (route build, fitBounds, timeline init).
+- **Verification**: Deployed to Pi and server. Rapid trip-switching no longer freezes.
+  Verified on both platforms 2026-08-11.
