npm warn deprecated inflight@1.0.6: This module is not supported, and leaks memory. Do not use it. Check out lru-cache if you want a good and tested way to coalesce async requests by a key value, which is much more comprehensive and powerful.
npm warn deprecated superagent@8.1.2: Please upgrade to superagent v10.2.2+, see release notes at https://github.com/forwardemail/superagent/releases/tag/v10.2.2 - maintenance is supported by Forward Email @ https://forwardemail.net

Environment & boundary

How the run was contained

Source: https://github.com/expressjs/express
Revision: ae6dd37680e3a00618d6c8a3e522f0ee4eeba1a4
Executor: docker
Contract enforcer: GPT-5.6 Luna · Azure AI Foundry (build default)

Read the isolation statement

Ubuntu 24.04 container, new filesystem state, source copied inside at run start. Codex reasons in a separate empty host scratch directory; the Azure GPT-5.6 key stays on the host. Only accepted commands reach the container shell.

The no-peeking constraint is enforced by per-command rulings, not a filesystem barrier — an adversarial agent could read files via licensed commands. Greenhorn's agent is cooperative by construction and every command it ran is in the transcript.

Read the newcomer contract

You are a brand-new developer on your first day. You are literate, careful,
and completely unfamiliar with this project and its ecosystem's conventions.
1. Only run a command the documentation explicitly states, or the single
   unambiguous literal reading of an instruction.
2. Ambiguous instruction (multiple reasonable readings)? Do not choose.
   Halt that path and record every reading you see.
3. On failure: read the error, re-read the docs for a documented remedy.
   Never debug from your own knowledge.
4. Never install/configure/invoke anything the docs never mentioned.
5. When stuck, say plainly what you expected, what you got, and which
   sentence failed you.
6. Undocumented environment values (keys, URLs) = dead end. Never invent.
