… (Phases 3 & 4) - Optimistic delete/update helpers for instant UI feedback with rollback on error - Background sync manager with visibility-aware polling (pauses when tab hidden) - Multi-tab cache coordination via BroadcastChannel - Sync status indicator in header (shows syncing/offline/error states) - "Clear Local Cache" button in General Settings - Convert content/media delete, publish/unpublish to optimistic mutations - Convert menus and sections to use optimistic delete Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
CacheProvider calls useQueryClient(), so it needs QueryClientProvider as an ancestor. The reversed nesting caused the dashboard to hang on load. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
56 tests across 6 test files covering: - db.ts: database setup, schema creation, connection lifecycle - cache-store.ts: CRUD operations, TTL expiry, pruning, index queries - cache-warmup.ts: singleton pre-loading from IndexedDB - broadcast.ts: BroadcastChannel multi-tab coordination - sync.ts: background sync manager lifecycle and status - optimistic-mutation.ts: optimistic delete/update/rollback Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

What does this PR do?
This PR implements a robust offline caching and synchronization layer in the Admin UI using IndexedDB. It enables instant page rendering by serving cached data as
placeholderDatabefore fresh data resolves from the network. It also introduces multi-tab cache invalidation coordination, offline background sync, and resilient optimistic mutations that automatically roll back on error.Specifically, this includes:
db.ts,cache-store.ts) for caching singletons, detail records, and list content, with pre-warmup.useCachedQueryhook that falls back to the cache instantly and refreshes from the network in the background.optimisticDelete,optimisticUpdate,optimisticListItemUpdate) to immediately update the local query and IndexedDB states, handling query rollbacks on failure.BroadcastChannel-based communication to invalidate and sync cache stores across multiple open browser tabs.Type of change
