# 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`)

## Files Created or Modified
| File Path | Action | Description |
|-----------|--------|-------------|
| `supabase/functions/create-reservation/index.ts` | Modified | Auth: `getClaims` → `adminClient.auth.getUser(token)`; `claims.sub` → `user.id` |
| `tests/integration/booking-constraints.test.ts` | Modified | `weekSlot` key names fixed; overlap test days spread across weeks |
| `tests/e2e/auth.spec.ts` | Modified | Assertion changed from missing text to `"Upcoming Reservations"` |
| `app/app.vue` | Modified | `v-if="authStore.user"` on `IonMenu` |
| `package.json` | Modified | Added `test:all` script |
| `CLAUDE.md` | Modified | Added Edge Functions section: SELinux fix, auth pattern, `security_invoker` note |
| `supabase/migrations/20260420180000_drop_open_reservations_read_policy.sql` | Created | Drops `"Authenticated users can read non-private reservation slots"` policy |
| `supabase/migrations/20260420190000_fix_reservation_slots_view.sql` | Created | Recreates `reservation_slots` with `security_invoker = false`; grants SELECT to authenticated |
| `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
