Contacts 5xx no longer early-returns from fetchFor, leaving the entire
right panel blank. A new contactsError ref surfaces the failure message
in the Email tab only; JD tab, Cover Letter tab, and match score all
render normally. Adds test asserting partial degradation behavior.
- Check error from POST /research/generate; only start pollTask on success to prevent unresolvable polling intervals
- Surface contacts and fullJob fetch errors in fetchFor; silently ignore research 404 (expected when no research yet)
- Remove redundant type assertions (as Contact[], as TaskStatus, as FullJobDetail)
- Add @internal JSDoc to pollTask
- Remove redundant vi.runAllTimersAsync() after vi.advanceTimersByTimeAsync(3000) in test
Delete useApiFetch.ts wrapper (returned T|null) and update prep.ts and
prep.test.ts to import useApiFetch from useApi.ts directly, destructuring
{ data, error } to match the established pattern used by all other stores.
Adds usePrepStore (Pinia) for interview prep data: parallel fetch of
research brief, contacts, task status, and full job detail; setInterval-
based polling that stops on completion and re-fetches; clear() cancels
the interval and resets all state. Also adds useApiFetch composable
wrapper (returns T|null directly) used by the store.
Setup-form Pinia store with per-stage computed lanes, optimistic status
mutation on move, and API-error rollback. Shallow-copies API response
objects on fetch to prevent shared-reference mutation across tests.
