Research direction

The report only identifies a 404 from https://chatgpt.com/backend-api/codex/responses and does not name a file, test, platform, or expected behavior. Start by reproducing the request and tracing where this endpoint is handled; the issue is done when the cause of the 404 is identified and the expected Codex response works or the failure is clearly documented.
