+- updated Android Studio, ran Upgrade Assistant for Android Gradle Plugin to 8.13.2
+- added Pixel 8 emulator
+- ran a few fixes:
+  - `779ad6` - upped app memory to 2GB from 500MB - investigate?
+  - `7671416` - app.settings needs the SynqApp cast — same as dao. And it's unused in milestone 2 anyway, so just removed it

 - base url configurable in app settings or build config.
 - bearer token configurable in app settings or build config.
 - client can call `/health`.
 - client can post capture payload.
-** TODO implement manual sync
+*** notes
+SynqApiClient in data/api/. OkHttp with 10s timeouts. checkHealth() does GET /health, returns false on any exception so callers never crash. postCapture() maps 401 → failed, non-2xx → failed, already_seen → AlreadySeen, else → Accepted. Uses org.json for request building, kotlinx-serialization for tag decoding.

 - sync now posts all pending captures.
 - successful posts mark rows synced.
 - already-seen response marks row synced.
 - failures retain pending/failed status and last error.
-** TODO implement opportunistic workmanager sync
+*** notes
+syncPending() top-level function in data/sync/SyncService.kt — shared by manual sync and WorkManager. CaptureViewModel.syncNow() calls it on Dispatchers.IO, guards with isSyncing flag. Sync icon in top bar shows CircularProgressIndicator while running.

 - periodic sync is registered.
 - sync only runs when network is available.

 - worker does not block capture speed.
-** TODO add simple server reachability settings
+*** notes
+SyncWorker (CoroutineWorker) in data/sync/. Registered in SynqApp.onCreate() as KEEP unique periodic work (15-min interval, NETWORK_CONNECTED constraint). Health check before sync — exits quietly if server unreachable. Does not touch UI thread.
