Phase 1 cached only notes. Phase 2 brings the read-through pattern to every domain the app reads in bulk: - Drift schema v2: 5 new cached_* tables + onUpgrade migration. Calendar events use range-scoped read/write (replaceEventsInRange) so disjoint month fetches don't clobber each other; milestones are per-project. - Wrap TasksRepository, ProjectsRepository, MilestonesRepository, and ChatRepository (conversation list only) with NetworkException fallback. Writes hit the API then sync the cache. - New EventsRepository wrapping EventsApi; calendar_provider and event_form_sheet repointed at the repository. - OfflineBanner now surfaces getLatestSync() — most-recent timestamp across all domains — so the hint reads sensibly regardless of screen. flutter analyze clean; existing tests pass. Phase 3 (offline write queue) and Phase 4 (read-only UI indicators) still to come. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
