Research direction

Start by reproducing the failure when starting a new chat and inspect the request to https://chatgpt.com/backend-api/codex/responses. Check the Codex code path that creates this request and determine why it receives a 404 authentication error. Done means the new-chat flow no longer produces this 404, with a regression test if the relevant code path supports one.
