- E2E seed creates API key instead of user for authentication
- Auth service tests cover only API key CRUD (removed user/session tests)
- Auth middleware tests validate three-way auth: API key, Bearer token, OIDC session
- Auth route tests mock getAuth for OIDC session, test /me and /keys endpoints
- Remove all references to createUser, verifyPassword, createSession in auth tests
