test(02-04): CalendarShell CAL-03 render smoke — Temporal hydration + Pitfall 6 guard
- CalendarShell.test.tsx: 6 tests covering render-without-throw, ScheduleXCalendar mount, hydrateEvents called with both timed + all-day occurrences, Temporal.PlainDate guard (Pitfall 4/all-day date shift), Temporal.ZonedDateTime for timed (Pitfall 4) - test-setup.ts: window.matchMedia polyfill for jsdom (calendarStore initialises at module load) - vitest.config.ts: adds setupFiles pointing to test-setup.ts

/**
|
||||
* CalendarShell render smoke test — CAL-03
|
||||
*
|
||||
* Guards:
|
||||
* - Pitfall 4: hydrateEvents is called before eventsService.set(); no ISO-string rejection
|
||||
* - Pitfall 6: @schedule-x/react@4.1.0 ↔ @schedule-x/calendar@4.6.0 compatibility —
|
||||
* useCalendarApp and ScheduleXCalendar are called without throwing
|
||||
*
|
||||
* Strategy: mock @schedule-x/react (Preact internals are not jsdom-compatible) so the test
|
||||
* focuses on the CalendarShell data pipeline (fetchMe → fetchEvents → hydrateEvents →
|
||||
* eventsService.set), not on Schedule-X's internal DOM rendering.
|
||||
* hydrateEvents is spied on to verify the all-day PlainDate path and the timed ZonedDateTime
|
||||
* path are both invoked without error (the Temporal hydration contracts from hydrateEvents.test.ts).
