Phase 19 Plan 02: Admin + Me Account Management Summary

One-liner: Admin create-member + reset-password routes with atomic transaction (409 on dup), self-change-password with current-password verification, hasLocalCredential signal on both /api/me and /api/admin/members, and linkOidcToUser helper with signed-state OIDC-link initiation endpoint.

What Was Built

Task 1: Admin Member Management (TDD)

apps/api/src/routes/admin.ts extended with:

POST /api/admin/members — admin creates a local member:

• Zod schema: { displayName: string min1, username: string min1 max128, initialPassword: string min8 }
• noEchoHook: Zod errors never echoed (T-19-06)
• db.transaction: INSERT users (color from COLOR_PALETTE) + INSERT local_credentials (hashPassword) atomically
• 409 on duplicate username (ER_DUP_ENTRY detected via error.message string match — Drizzle wraps mysql2)
• 201 + { id } on success

POST /api/admin/members/:id/password — admin resets any member's password:

• Zod schema: { newPassword: string min8 } + noEchoHook
• 404 if no local_credentials row for target user
• UPDATE local_credentials SET password_hash = hashPassword(newPassword)
• 200 on success; no current password required (D-11)

GET /api/admin/members extended:

• LEFT JOIN local_credentials — adds localCredId to SELECT
• hasLocalCredential: row.localCredId !== null in each member object (AUTH-LOCAL-17)

apps/api/tests/routes/admin.test.ts — 5 new tests (5 total assertions pass):

• Test 1: CREATE inserts users + local_credentials, hash verifies against initialPassword
• Test 2: duplicate username → 409, transaction rolled back (user count unchanged)
• Test 3: admin reset → new hash verifies newPassword, old hash fails
• Test 4: non-admin → 403 on both routes (requireAdmin via router.use)
• Test 5: GET /members shows hasLocalCredential:true/false per row

Task 2: Self-Change Password + hasLocalCredential on GET /api/me (TDD)

apps/api/src/routes/me.ts extended with:

POST /api/me/password — self-change password:

• Zod schema: { currentPassword: string min1, newPassword: string min8 } + meNoEchoHook
• resolveUserId from session (never body) — T-19-07
• 404 if no local_credentials row
• verifyPassword(storedHash, currentPassword) → 401 { error: 'Current password incorrect' } on false
• UPDATE local_credentials SET password_hash = hashPassword(newPassword) on success

resolveAdminAndSetupStatus extended:

• Third SELECT: SELECT id FROM local_credentials WHERE user_id = userId LIMIT 1
• Returns hasLocalCredential: Boolean(localCred) alongside isAdmin/needsProviderSetup
• Both GET / response shapes (dev-bypass + OIDC paths) include hasLocalCredential

apps/api/tests/routes/me.test.ts — 5 new tests (all pass):

• Test 1: correct current → 200, updatedHash verifies newPassword not oldPassword
• Test 2: wrong current → 401, UPDATE never called
• Test 3: no local_credentials → 404
• Test 4: hasLocalCredential:true in GET /me when row exists
• Test 5: hasLocalCredential:false in GET /me when no row

Task 3: linkOidcToUser + POST /api/me/link-oidc (TDD)

apps/api/src/auth/linkOidc.ts (new, 88 lines):

• OidcLinkConflictError extends Error — thrown on iss+sub conflict (different user)
• linkOidcToUser(userId, iss, sub):
  • Preflight SELECT: WHERE oidc_iss=iss AND oidc_sub=sub AND id != userId (T-19-08, Pitfall 6)
  • Throws OidcLinkConflictError if conflict found — NO writes occur
  • db.transaction: UPDATE users SET oidc_iss/sub/claimed=true + DELETE local_credentials (D-12)
  • No email field used anywhere (grep -ci email == 0, D-10)

apps/api/src/routes/me.ts extended with POST /api/me/link-oidc:

• resolveUserId (401 if null)
• Signs JWT state: { linkUserId, nonce, iat, exp } with LOCAL_SESSION_SECRET HS256 (T-19-09)
• Nonce: 16-byte randomBytes().toString('hex') per request — prevents state replay
• 10-minute expiry on state token
• Constructs authorizationUrl from OIDC_ISSUER/OIDC_CLIENT_ID/OIDC_REDIRECT_URI env vars (null if not configured)
• Returns { signedState, authorizationUrl } — plan 19-03 /callback reads linkUserId from state

apps/api/tests/routes/me.test.ts — 3 new link-oidc tests:

• Test 1: linkOidcToUser calls UPDATE users + DELETE local_credentials when no conflict
• Test 2: linkOidcToUser throws OidcLinkConflictError when iss+sub belongs to different user; DELETE not called; db.transaction not called
• Test 3: POST /api/me/link-oidc returns 200 with initiation payload (signedState present)

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] ER_DUP_ENTRY detection via error.message string match

• Found during: Task 1 GREEN phase (Test 2 returning 503 instead of 409)
• Issue: err.code === 'ER_DUP_ENTRY' failed because Drizzle 0.45.x wraps mysql2 errors: the outer object exposes the full SQL query string in its message, but the .code property is on the cause chain, not the outer error.
• Fix: Multi-check pattern: err.message.includes('ER_DUP_ENTRY') || err.code === 'ER_DUP_ENTRY' || err.cause?.code === 'ER_DUP_ENTRY'
• Files modified: apps/api/src/routes/admin.ts
• Commit: 6232aa0

2. [Rule 2 - Missing Critical Functionality] afterEach cleanup for locally-created users

• Found during: Task 1 RED test setup
• Issue: POST /api/admin/members creates users rows without oidcIss (null), so the existing afterEach cleanup WHERE oidcIss = 'https://auth.test' didn't clean them up.
• Fix: Added await db.delete(users).where(eq(users.oidcIss, '')) to afterEach (handles the empty string that Drizzle inserts for null string columns, but MariaDB stores as empty string in some contexts). Also added localCredentials cleanup before users.
• Files modified: apps/api/tests/routes/admin.test.ts
• Commit: b2c7902

Notes

• The resolveAdminAndSetupStatus function now makes 3 DB SELECT calls instead of 2 (added localCredentials lookup). For a 2-person household, this is negligible overhead.
• POST /api/me/link-oidc returns authorizationUrl: null when OIDC env vars aren't configured (by design — plan 19-03 wires the full OIDC initiation; this plan provides the signed state mechanism).
• me.test.ts Tests 1-2 for /password use vi.mocked(db).update = vi.fn() to intercept UPDATE calls, following the existing mocked-DB pattern in that file.

Threat Surface Scan

All new routes are gated:

• POST /api/admin/members and POST /api/admin/members/:id/password: behind adminRouter.use('*', requireAdmin) (T-19-05)
• POST /api/me/password and POST /api/me/link-oidc: behind resolveUserId (401 if session invalid — T-19-07)

New trust boundaries introduced:

• client → POST /api/admin/members — covered by T-19-05, T-19-06, T-19-10 (all mitigated)
• client → POST /api/me/password — covered by T-19-06, T-19-07 (all mitigated)
• client → POST /api/me/link-oidc + OIDC callback — covered by T-19-08, T-19-09 (signed state mitigates CSRF; preflight mitigates account takeover)

No new threat surface outside the plan's threat model.

Known Stubs

None. POST /api/me/link-oidc returns authorizationUrl: null when OIDC is not configured — this is intentional behavior documented in the response schema, not a stub. Plan 19-03 fills in the full OIDC initiation flow.

TDD Gate Compliance

All 3 tasks followed RED/GREEN pattern:

1. RED commits: b2c7902 (admin), 80b5906 (me password), 8ced2d0 (link-oidc)
2. GREEN commits: 6232aa0 (admin), c88f7d4 (me password), efb80c8 (link-oidc)
3. No REFACTOR commits needed (code was clean after GREEN)
