watchSyncStatus abstract method

Stream<SyncStatus> watchSyncStatus()

The live SyncStatus stream (spec §3.3). Emits the CURRENT status immediately on subscribe (so a re-subscribe after a background gap re-renders at once), then every change coalesced latest-wins. It NEVER completes on a transient fault — a stall is a SyncStatus.stalled EVENT, not an error or EOF.

Implementation

Stream<SyncStatus> watchSyncStatus();
