 - capture entity has id, created_at, kind, body, tags, device, status, synced_at, and last_error.
 - saving creates pending row.
 - pending captures survive app restart.
-** TODO implement capture id generation

+CaptureEntity, CaptureDao, CaptureDatabase in data/db/. Tags stored as JSON string (kotlinx-serialization). DB name synq.db, singleton via companion object. Room persists across restarts by default.

 *** acceptance
 - id format is stable and readable, e.g. `phone-yyyymmdd-hhmmss-rand`.
 - ids are generated client-side.
 - tests or simple assertions prevent blank/duplicate ids in normal flow.

 - lists recent captures.
 - shows pending/synced/failed status.
 - failed row shows last error.
 - user can retry failed/pending sync.
+*** notes
+HistoryScreen.kt observes captureDao.observeAll() as Flow. Status colored green/red/grey. Retry button shown for pending/failed; calls updateStatus(id, "pending", null) so the sync worker picks it up in milestone 3.
