fix(docker): run as root so Codex can read auth.json#266
Merged
Conversation
Codex stores its API key in /root/.codex/auth.json at runtime. Running the Node process as a non-root tinyagi user via gosu meant Codex could not read the auth file, causing WebSocket 500 errors against the OpenAI Responses API. Switch Docker to run as root directly — container isolation is handled by gVisor at the infrastructure level, making the in-container user separation unnecessary. Also fix Codex adapter to always use `resume --last` by default and auto-reset on first invocation for new agent directories. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
