Session Handoff: Edge Functions, Auth Pattern, and Test Fixes

Date: 2026-04-20 Session Duration: ~2 hours Session Focus: Fix create-reservation Edge Function auth, resolve 12 failing integration tests, fix RBAC RLS, add SELinux dev docs Context Usage at Handoff: ~60%

What Was Accomplished

1. Diagnosed and fixed SELinux blocking Edge Functions locally → documented fix in CLAUDE.md
2. Updated Edge Function auth from userClient.auth.getUser() (anon key + auth header) to adminClient.auth.getUser(token) (service role + JWT arg) → supabase/functions/create-reservation/index.ts
3. Fixed weekSlot() test helper returning {start, end} instead of {start_time, end_time} → tests/integration/booking-constraints.test.ts
4. Fixed overlap tests using days 30/31/32 (same ISO week, hitting weekly pre-booking limit before DB overlap constraint fires) → spread across days 14/21/28 (different weeks)
5. Fixed RBAC: "Authenticated users can read non-private reservation slots" policy on reservations was never dropped when reservation_slots view was created → new migration drops it
6. Fixed reservation_slots view from security_invoker = true to security_invoker = false so it reads as owner, not caller → new migration recreates view + grants
7. Fixed E2E test asserting "Welcome to OYS Borrow a Boat" (doesn't exist) → changed to "Upcoming Reservations" which is always present when authenticated
8. Added v-if="authStore.user" to IonMenu in app.vue — menu not rendered before login
9. Added yarn test:all script (unit → integration → e2e in sequence)

Decisions Made This Session

• Use adminClient.auth.getUser(token) (not getClaims) BECAUSE getClaims is not reliably available in npm:@supabase/supabase-js@2 Deno import and its return shape is undocumented for that context — STATUS: confirmed
• reservation_slots view uses security_invoker = false BECAUSE security_invoker = true caused it to apply the calling user's RLS (returning 0 rows for non-owners after broad policy was dropped) — STATUS: confirmed
• Overlap tests use weeks 14/21/28 days ahead BECAUSE original days 30/31/32 fell in the same ISO week; direct insert on day+31 consumed the 2nd weekly pre-booking slot, blocking the day+32 "different time" test — STATUS: confirmed

Key Numbers Generated or Discovered This Session

• Integration tests before: 12 failed / 8 passed (20 total)
• Integration tests after: 0 failed / 20 passed (ASSUMED — verify with yarn test:integration)
• E2E tests: 1 failed / 1 passed → 2 passed after auth text fix (ASSUMED — verify with yarn test:e2e)

supabase/migrations/20260420132336_booking_rules_and_rbac.sql	Modified	Fixed original view creation to security_invoker = false + added GRANT for db reset consistency

What the NEXT Session Should Do

1. First: Verify all tests pass — yarn test:all (requires local Supabase running with functions served)
2. Then: Work on reservations UI — app/pages/reservations/ exists but contents unknown; likely needs create/list/detail pages wired to the Edge Function

Open Questions Requiring User Input

• What pages exist under app/pages/reservations/? Are they scaffolded or complete? — impacts next UI session scope
• Are there additional Edge Functions planned (e.g., cancel-reservation, admin endpoints)? — impacts function auth pattern reuse

Assumptions That Need Validation

• ASSUMED: yarn test:all passes cleanly after migrations applied — validate by running npx supabase migration up && yarn test:all
• ASSUMED: reservation_slots view grant is sufficient for anon client queries in tests — validate by observing RBAC test pass
