+## Code Review Complete (2025-12-25)
+
+All acceptance criteria implemented:
+
+**AC #1 - Board renders from IndexedDB offline:**
+- Board.tsx line 1225: `isOfflineWithLocalData = !isNetworkOnline && hasStore`
+- Line 1229: `shouldRender = hasStore && (isSynced || isOfflineWithLocalData)`
+
+**AC #2 - Working Offline indicator:**
+- ConnectionStatusIndicator shows 'Working Offline' with purple badge
+- Detailed message explains local caching and auto-sync
+
+**AC #3 - Changes saved locally:**
+- Automerge Repo uses IndexedDBStorageAdapter
+- Changes persisted via handle.change() automatically
+
+**AC #4 - Auto-sync on reconnect:**
+- CloudflareAdapter has networkOnlineHandler/networkOfflineHandler
+- Triggers reconnect when network returns
+
+**AC #5 - No data loss:**
+- CRDT merge semantics preserve all changes
+- JSON sync fallback also handles offline changes
+
+**Manual testing recommended:**
+- Test in airplane mode with browser reload
+- Verify data persists across offline sessions
+- Test online/offline transitions
