Codex CLI built it with jose

Prompt: Add authentication to a Next.js App Router app, including a middleware/proxy that redirects unauthenticated users.

Grader: The agent built a self-contained auth system with env-configured credentials, jose-signed session cookies, scrypt password hashing, login/logout, a src/proxy.ts redirect for unauthenticated users, and a server-side dashboard check; build, tests, lint and HTTP checks passed, though one ad-hoc verification script failed on an Invalid URL and a hash script hit a CJS top-level-await error before being fixed.
