Summary

Automatically sync offline changes when connectivity is restored, with conflict detection and resolution.

Implementation Tasks

  • Detect connectivity changes (online/offline events)
  • Push dirty notes to server on reconnect
  • Pull remote changes and merge with local state
  • Detect conflicts (local and remote both modified since last sync)
  • Present conflict resolution UI to user
  • Update sync timestamps after successful sync

Conflict Detection Strategy

  • Compare synced_at timestamps with server updated_at
  • If both changed since last sync, flag as conflict
  • Resolution options: keep local, keep remote, or manual merge

Acceptance Criteria

  • Offline edits sync automatically when reconnected
  • Concurrent edits on same note trigger conflict detection
  • User can resolve conflicts via UI
  • Sync state is visible (pending, syncing, synced, conflict)
