jubnl	4188f67ab7	fix(sync): remap temp ids, prevent id collisions, surface failed mutations (#1175) ... Closes three offline BLOCKERs from the PWA audit: - B1: offline edits/deletes of an offline-created entity were lost. The negative temp id was baked into the PUT/DELETE url and never rewritten after the CREATE returned a real id, so dependents 404'd and were dropped. Dependents now carry a {id} placeholder + tempEntityId; flush builds a tempId->realId map and durably rewrites still-queued dependents on CREATE success (survives flush boundaries / reloads). - B2: tempId = -(Date.now()) collided within a millisecond, overwriting an optimistic row. Replaced with a monotonic nextTempId() minter. - B3: any 4xx marked the mutation failed with no rollback and no signal, and the badge ignored failed rows. Terminal failures now roll back the phantom optimistic CREATE; 401/408/425/429 are treated as retryable; failedCount() is surfaced in OfflineBanner (red pill) and OfflineTab.	2026-06-15 07:51:52 +02:00
jubnl	b194e8317d	feat(pwa): implement real offline mode with IndexedDB sync ... Add genuine offline read/write capability for trips: - Dexie IndexedDB schema (trips, places, packing, todo, budget, reservations, files, mutationQueue, syncMeta, blobCache) - Repo layer for all domains: offline reads from Dexie, writes optimistically to Dexie and enqueue mutations for later replay - Mutation queue with UUID idempotency keys (X-Idempotency-Key), FIFO flush, temp-ID reconciliation on 2xx, fail-and-continue on 4xx - Trip sync manager: caches all trips with end_date >= today or null, auto-evicts 7d after end_date, fetches bundle endpoint in one request - Map tile prefetcher: bbox from place coords, zooms 10-16, 50MB cap, warms SW cache via fetch - Sync triggers: network online → flush + syncAll; WS reconnect → flush only (rate-limiter safe); visibilitychange/30s → flush only - WS remoteEventHandler writes through to Dexie on every event - Server idempotency middleware + idempotency_keys table (migration 100, 24h TTL nightly cleanup) - GET /api/trips/:id/bundle endpoint for efficient single-request sync - OfflineBanner component: amber (offline) / blue (syncing) / hidden - OfflineTab in Settings: cached trip list, re-sync and clear actions - usePendingMutations hook for per-item pending indicators Closes #505 #541	2026-04-14 23:04:25 +02:00
