Enqueue a full ExoBrain re-train for the caller’s org and return immediately with the job id. Requires the admin scope.Only one train may be in flight per org: a second request while one is queued or running returns 409. Poll GET /v1/brain/info for progress. The new artifact is published only after it passes its numerical parity gate, so a failed train leaves the previous brain serving.
This route requires the admin scope.A missing or invalid credential returns 401 authentication_error. A valid credential without the scope returns 403 permission_denied, and the problem body names the exact scope required.
