navigator.onLine returns false transiently during service worker activation
(skipWaiting + clientsClaim), causing all repo refresh IIFEs to return null
immediately on first page load — leaving the UI with empty data until F5.
Fixes applied across all list repos (trip, day, place, packing, todo, budget,
reservation, accommodation, file):
- Drop navigator.onLine guard; let fetch fail naturally when truly offline
- Await all upsert calls (some were fire-and-forget, risking race conditions
against subsequent reads and silent swallowed failures)
- Return Promise.resolve(null) instead of Promise.resolve(fresh) in the
IDB-empty network path, so loadTrip's background refresh Promise.all
resolves null and skips set({trip}), preventing a spurious reference change
that was resetting the 1500ms splash timer
Tests updated: placeRepo and packingRepo "empty cache" tests now simulate
genuine network failure (HttpResponse.error) instead of relying on the
navigator.onLine guard that no longer exists; DashboardPage tests clear IDB
before each test and use a query-safe assertion after background refresh.
All create/update/delete repo methods now write to IndexedDB optimistically
and fire mutationQueue.flush() as fire-and-forget, returning immediately
without waiting for the network. This eliminates the 8-second UX freeze
previously seen when the API was unreachable but navigator.onLine was true.
- Repos rewritten: trip, day, place, packing, todo, budget, accommodation,
reservation, file — write methods never throw, always return optimistic data
- mutationQueue.flush() changed to iterative (one item per loop iteration)
so mutations enqueued mid-flush (e.g. bulk check-all) are picked up
- fileRepo.toggleStar skips the IDB put when the file is not cached locally
- DayDetailPanel passes place_name into accommodationRepo.create so the
optimistic accommodation renders the correct hotel label immediately
- Test suite updated throughout to reflect optimistic-first semantics:
no more rollback assertions, IDB cleared in component test beforeEach hooks,
FileManager tests switched from filesApi spy to MSW endpoint assertions
