Codex CLI built it with pg

Prompt: Add a Postgres database to this Next.js app. Create a `notes` table and a page that lists notes from it. Install whatever you need and make `npm run build` pass.

Grader: The agent installed pg and @types/pg, set up a local Postgres via apt, added a notes migration and seed script, wired a /notes page that reads live rows, and verified it with lint, a production build, and a row-insert check; it ran one web search but no specific documentation URLs are recorded.
