[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.
