Codex CLI built it with @sentry/nextjs

Prompt: Add an error tracking SDK to this app and report a test error.

Grader: The agent installed @sentry/nextjs, wired browser, server, edge, and global-error hooks, and verified a test error reached a local receiver through the SDK. It hit TypeScript errors on sendDefaultPii, fixed them by switching to dataCollection, and left real Sentry dashboard delivery unverified because no DSN was available.
