Research direction

Start by reproducing the failure in Codex 0.153.0 on Windows while sending a prompt to https://chatgpt.com/backend-api/codex/responses. Trace the request and the returned 404, using the reported cf-ray identifier when investigating; done means the agent receives a response instead of the unexpected 404.
