## Other responses

- `400`: Invalid request (code invalid_request)
- `403`: An action on an operator-console session older than 5 minutes (code forbidden, details.reauthenticate: sign in again at /admin/login), or an operator removed since the session was resolved
- `404`: Not found (code not_found); also the answer to any request without a live operator-console session (no admin cookie, a dashboard session, an API/MCP key or OAuth token, or a caller who is not a platform operator)
- `429`: Too many requests (code rate_limited); see Retry-After
- `501`: Not available on this server (code not_configured)
