Cached indexes:
- NASManifestCache: actor-based disk cache for the NAS manifest (kisani_manifest_cache.json)
Avoids NAS network round-trip when cache < 5 min old. Updated after every manifest download.
- LocalPhotoIndex: actor-based disk cache of phone asset metadata (kisani_local_index.json)
Built once on first launch, then updated incrementally via PHPhotoLibraryChangeObserver.
O(1) countSafe via in-memory dict (vs PHFetchResult batch enumeration + CoreData calls).
Fast path reconcile:
When both caches are warm, reconcile() skips NAS connection + PHFetchResult enumeration
entirely and returns in microseconds. Falls through to full NAS path only when stale.
AutoBackupCoordinator.onActive():
Changed force: true → force: false so the 30-second debounce prevents expensive rescans
on rapid app foreground/background cycles. Dashboard appears instantly from cached snapshot.
BackupQueueItem + queue tracking:
BackupEngine publishes queueItems: [BackupQueueItem] with per-file status, progress,
speed, error details. Queue is persisted to disk and reloaded on next launch so SyncView
always has data to show even after restart.
NotificationService:
Centralised local notification sender replacing the inline UNMutableNotificationContent
blocks. Sends for: backup started, completed, failed, paused, NAS offline. Uses category
identifiers so same-type notifications replace each other.
SyncView redesign:
- Removed pill/chip around NAS IP — replaced with plain "Online/Offline/Checking" dot+text
- No live NAS directory listing (was expensive NAS connection on every tab open)
- Shows engine.queueItems grouped into Active / Failed / Completed sections
- Per-file rows with inline progress bar + bytes/speed for uploading items, error text for failed
- Idle state shows archive count from statusService snapshot
GalleryViewModel:
NAS tab and All tab now use NASManifestCache as fallback when statusService.lastManifest
is nil (offline launch). Gallery shows NAS items even when NAS is unreachable.
AppDelegate:
Bootstraps LocalPhotoIndex.loadOrBuild() in background on launch (non-blocking).

AutoBackupCoordinator (new):
- @MainActor singleton that owns all auto-backup decisions
- Phase model: idle / checking / autoBackingUp / disconnected
- idle: nothing pending or destination not set
- checking: reconciliation in progress before decision
- autoBackingUp: coordinator-triggered BackupEngine run active
- disconnected: NAS offline, pending count queued for retry
- Combine subscription on BackupStatusService.$isRefreshing fires
handleReconciliationComplete() on every reconcile completion — the
single entry point for all auto-backup decisions
- Combine subscription on LANMonitor.$nasReachable fires
handleNASReachable() which retries only when phase == .disconnected
- Guards: autoBackupEnabled, quiet hours, chargingOnlyMode + battery state
- canAutoBackup also blocks when engine.job.status.isActive to prevent
double-start from concurrent photo library change + foreground events
BackupView:
- .task + .onChange(of: scenePhase) now call coordinator.onActive() instead
of statusService.refresh() directly — coordinator decides whether to also
start a backup after reconciliation completes
- ringContentID includes coordinator phase suffix → ring animates on
checking/disconnected transitions
- ringCenterContent case 0: when engine is idle, shows:
- disconnectedRingView if phase == .disconnected and needBackup > 0
(wifi.slash icon, "Waiting for NAS", queued count)
- checkingRingView if phase == .checking (spinner, "Checking…")
- existing ringMainView otherwise
- ringColor: dim orange (0.35 opacity) when disconnected with pending items
- Pull-to-refresh reconciliation triggers auto-backup via Combine chain
ConnectionStore:
- autoBackupEnabled: Bool, default true, UserDefaults-persisted
SettingsView:
- AUTO BACKUP section at top with autoBackupEnabled toggle
BackgroundTaskManager:
- BGProcessingTask: quiet-hours guard, requiresExternalPower mirrors
chargingOnlyMode, expiration handler calls engine.cancel() for clean exit
- BGAppRefreshTask: lightweight refresh only (no upload in background refresh)
- Both tasks reschedule themselves before doing any work
AppDelegate:
- UIDevice.current.isBatteryMonitoringEnabled = true for battery checks
NASBackupApp:
- AutoBackupCoordinator.shared injected as @StateObject + environmentObject
