- Create apps/api/src/auth/devBypass.ts: devAuthBypass() middleware with
NODE_ENV=production hard guard as first conditional (T-02-01 mitigation)
- Exports DEV_USER const (id:1, color:COLOR_PALETTE[0]) for test reference
- Mount devAuthBypass() before oidcAuthMiddleware on /api/* in index.ts
- Add devBypass.test.ts: all three behavioral cases pass (production guard,
unset-flag passthrough, active-injection)
- Add DEV_AUTH_BYPASS to .env.example with production warning comment
- Extend docs/deployment.md with dev-auth bypass section and production prohibition
- Mount /api/events, /api/sse in index.ts behind oidcAuthMiddleware; /callback + /health before guard
- Call startBrokerPoller() on boot (5-min ctag-poll background schedule)
- Add sseRouter with GET /heartbeat (streamSSE, 10s interval) for Pangolin SSE smoke test (D-08, T-04-01)
- Add CAL-08 spike script (broker/spike.ts): createFastmailClient → fetchCalendars → print calendar URLs
- Add fetchEvents() to pwa/api/client.ts with typed CalendarEvent/EventsResponse shapes
- Add EventProof.tsx: React Query ['events'], renders first event title+date or empty-state (CAL-01 broker proof)
- Update App.tsx to render MemberBadge + EventProof on landing page
- Add ical.js@2.2.1 to PWA dependencies for VEVENT summary parsing in EventProof
- All 24 API unit tests green; tsc --noEmit clean in both apps/api and apps/pwa
