SyncWorkerLoop is the upload+poll core, mirrored from doctate-client-core::server_sync::run. Pending uploads have priority over polling (no point asking the server for state if we still hold the doctor's audio). Backoff is in-process state — after restart it drops back to 2s and gives the server one fresh chance, which beats 'wait 60s because we cancelled mid-backoff'. Architecturally split into runOnce (single iteration, suspends only on real I/O) and run (infinite loop, suspends on idle). The split makes the loop directly testable on JVM virtual time without dealing with advanceUntilIdle vs. infinite-while semantics — tests call runOnce N times and assert in between. Wired through: - SyncService (foregroundServiceType=dataSync, low-importance silent notification, ServiceCompat.startForeground for API 34+) - SyncServiceLauncher replaces NoopSyncTrigger in DoctateApp - DoctateApp.onCreate kicks the service after StartupCleanup if the pending queue is non-empty (recovery from crash/reboot) - AndroidManifest: FOREGROUND_SERVICE / FOREGROUND_SERVICE_DATA_SYNC / POST_NOTIFICATIONS perms; service declaration 6 SyncWorkerLoopTest cases (success/transient/terminal/idle/fifo plus backoff-resets-after-success). 58 tests green total.
