relevant_claims:
  - GitHub warns that self-hosted runners do not provide clean, ephemeral isolation for every job.
  - GitHub recommends using self-hosted runners only with private repositories because repository forks can execute dangerous code through pull requests.
  - A persistent Jetson runner must not execute untrusted pull-request code.
