Robustness sweep, perf hotspots, full localization, coach gate
cascade closure.
- /api/dashboard/summary cold-mount 4.6 s → ~500 ms via DAY-bucket
sparkline + 60 s response cache.
- Coach API gate inventory test surfaced and closed two orphan
routes (chat[id] GET+DELETE, chat-message feedback POST).
- Cross-tz fast-path runtime guard falls back to live for users
more than ±3 h from UTC; proper bucket minting stays v1.5.
- es / fr / it / pl coverage 27 % → 63 % (~3 400 new strings) plus
three medication-cluster placeholder restorations.
- IANA timezone validation closes the User.timezone self-DoS
regression the new dashboard SQL would have surfaced.
- Unit suite 4520 → 4524.
See CHANGELOG.md for the full set.
Server-side prep for the next iOS TestFlight build. Five surfaces land together so the iOS engineer can pick them up in one cut-over: a locked externalId shape for daily-aggregated cumulative HealthKit rows, the SyncMode foundation columns + handshake + bulk-backfill endpoints, a first-class MoodEntry.note column that replaces the legacy tag-based workaround, a cross-source workout dedup helper, and two new MeasurementType enums plus the shared category overlay that drives the iOS permission picker and the future Insights nav.
