# Update Training Job Model Name

`PATCH /felix/training-jobs/{job_id}/model-name`

Update the model_name for a training job.

Thin wrapper: visibility scoping, validation, the UPDATE, and the
activity-event side effect all live in
:meth:`TrainingJobService.update_model_name`. The router only owns
HTTP concerns (status codes, request/response shaping) per
``brain/CLAUDE.md``.
