phase: 15-external-authentication
plan: 03
subsystem: auth
tags: [oidc, logto, react, tanstack-query, e2e, api-keys]

# Dependency graph
requires:
  - phase: 15-external-authentication (plan 02)
    provides: OIDC middleware, refactored auth routes, stripped auth service
provides:
  - OIDC-aware login page (redirect to Logto, no credential form)
  - Updated auth hooks matching new API response shape (string user id)
  - E2E seed using API keys instead of user table
  - Auth middleware tests for three-way auth (API key, Bearer, OIDC)
  - Auth route tests with mocked OIDC session
affects: [16-multi-user-data-model, e2e-tests]

# Tech tracking
tech-stack:
  added: []
  patterns:
    - "OIDC redirect login via window.location.href to server route"
    - "useLogout returns plain function (not mutation) for redirect-based logout"
    - "E2E tests authenticate via API key header, bypassing auth provider"
    - "Mock @hono/oidc-auth getAuth in tests with bun:test mock.module"

key-files:
  created: []
  modified:
    - src/client/hooks/useAuth.ts
    - src/client/routes/login.tsx

    - e2e/seed.ts
    - tests/middleware/auth.test.ts
    - tests/services/auth.service.test.ts
    - tests/routes/auth.test.ts

key-decisions:
  - "Login page renders redirect button rather than credential form"
  - "useLogout returns { logout } function (not useMutation) since it is a redirect"
  - "Removed ChangePasswordSection from settings (passwords managed by Logto)"
  - "E2E seed uses static API key string for deterministic test auth"

patterns-established:
  - "OIDC login: client redirects to server /login which triggers Logto redirect"
  - "Test mocking: mock.module for @hono/oidc-auth before importing middleware"
  - "E2E auth: API key in X-API-Key header, no dependency on auth provider"

# Phase 15 Plan 03: Client Auth UI, E2E Seed, and Test Updates Summary

**OIDC login redirect page, cleaned auth hooks (string user id, no credential forms), API-key E2E seed, and three-way auth test coverage**

## Performance

- **Duration:** 4 min
- **Started:** 2026-04-04T18:50:52Z
- **Completed:** 2026-04-04T18:54:28Z
- **Tasks:** 3 (2 auto + 1 checkpoint auto-approved)
- **Files modified:** 8

## Accomplishments
- Login page redirects to Logto via server-side OIDC instead of showing username/password form
- Auth hooks match new OIDC API response shape (user.id is string, no setupRequired)
- E2E seed creates API key for test authentication instead of inserting into removed users table
- Auth middleware and route tests validate all three auth paths with proper mocking

## Task Commits

Each task was committed atomically:

1. **Task 1: Rewrite login page and auth hooks for OIDC** - `79b27b6` (feat)
2. **Task 2: Update E2E seed script and auth-related tests** - `689a56b` (feat)
3. **Task 3: Verify OIDC login flow** - auto-approved checkpoint (no commit)

## Files Created/Modified
- `src/client/hooks/useAuth.ts` - Removed useLogin/useSetup/useChangePassword, updated AuthState to string id
- `src/client/routes/login.tsx` - Replaced credential form with OIDC redirect button
- `src/client/routes/settings.tsx` - Removed ChangePasswordSection, use authenticated flag
- `src/client/components/UserMenu.tsx` - Updated logout call from mutation to direct function
- `e2e/seed.ts` - API key creation instead of user insertion
- `tests/middleware/auth.test.ts` - Three-way auth tests with mocked getAuth and verifyAccessToken
- `tests/services/auth.service.test.ts` - API key CRUD tests only (removed user/session tests)
- `tests/routes/auth.test.ts` - GET /me with mocked OIDC, API key CRUD routes

## Decisions Made
- Login page renders a "Sign In" button that triggers `window.location.href = "/login"` for full-page navigation to server OIDC redirect
- useLogout returns a plain `{ logout }` object instead of useMutation since it performs a redirect, not an API call
- Removed ChangePasswordSection from settings entirely since passwords are managed in Logto
- Settings page API keys section gated on `auth?.authenticated` instead of `auth?.user`
- E2E seed uses a static deterministic API key string for reproducible test runs

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 3 - Blocking] Updated UserMenu.tsx for new useLogout API**
- **Found during:** Task 1 (Rewrite auth hooks)
- **Issue:** UserMenu called `logout.mutate()` but new useLogout returns `{ logout }` function, not a mutation
- **Fix:** Changed `logout.mutate()` to `logout()` in UserMenu onClick handler
- **Files modified:** src/client/components/UserMenu.tsx
- **Verification:** No remaining `logout.mutate` references in codebase
- **Committed in:** 79b27b6 (Task 1 commit)

**2. [Rule 3 - Blocking] Removed ChangePasswordSection from settings page**
- **Found during:** Task 1 (Rewrite auth hooks)
- **Issue:** Settings page imported and used `useChangePassword` which was removed from hooks; page would not compile
- **Fix:** Removed entire ChangePasswordSection component and its import from settings.tsx
- **Files modified:** src/client/routes/settings.tsx
- **Verification:** No references to useChangePassword remain in client code
- **Committed in:** 79b27b6 (Task 1 commit)

---

**Total deviations:** 2 auto-fixed (2 blocking issues)
**Impact on plan:** Both fixes were necessary to keep the client compiling after hook removals. No scope creep.

## Deferred Items
- `tests/routes/oauth.test.ts` still references `createUser` from old auth service (pre-existing, not caused by this plan)

## Issues Encountered
None

## User Setup Required
None - no external service configuration required for this plan (infrastructure was set up in Plan 01).

## Next Phase Readiness
- Client auth UI complete and aligned with OIDC backend from Plan 02
- E2E seed ready for API-key-based test authentication
- All auth-related unit/integration tests updated for new architecture
- Phase 15 external authentication integration is complete across all three plans
