- Delete the 'db:push': 'drizzle-kit push' entry from scripts
- Retain db:generate and db:migrate as the canonical workflow
- JSON remains valid; no other changes
- Add react-router@7, @dnd-kit/core, @dnd-kit/sortable, fractional-indexing to PWA
- Add fractional-indexing to API (rank generation server-side)
- ioredis NOT added (in-memory EventEmitter per RESEARCH Plan 02 justification)
- Create apps/api/test/setup.ts with afterEach DB cleanup for list tables
- Wire test.setupFiles in apps/api/vitest.config.ts
- Add 4 Wave-0 RED stub test files (LIST-01/02/03/04, D-04, D-11, D-07)
- All stubs run as todo, not import-error
Temporal.ZonedDateTime.from() rejects offset-only ISO strings such as
'2026-06-18T08:00:00-04:00'; it requires an IANA bracket, e.g.
'2026-06-18T08:00:00-04:00[America/New_York]'. serializeTime() was
emitting offset-only for named zones and bare 'Z' for UTC — both
unparseable by the frontend, blanking the calendar view.
Changes:
- Named IANA zone: emit '...±HH:MM[tzid]' using t.zone.tzid
- UTC zone: strip trailing 'Z' from toString(), emit '+00:00[UTC]'
- Floating zone (no registered VTIMEZONE): fall back to '+00:00[UTC]'
- Update CalendarOccurrence docstrings to reflect the IANA-annotated contract
- Add temporal-polyfill@0.3.2 as dev dep in api for cross-contract test
