It should: queue mutations in a local SQLite database when offline, replay queued mutations when connectivity is restored (in order), handle conflict resolution (server wins by default, with custom resolver option), support partial sync (only changed records since last sync timestamp), retry failed syncs with exponential backoff, and emit events for sync status changes."
