# Production wiring (forgejo-runner on ghost):
#   - forgejo-runner v13: docker_host: automount -> the job container gets the
#     host docker socket, so docker_grade.sh drives the host daemon as designed
#   - hidden tests mount from the runner host via the nested docker run
#     (-v /opt/grade-hidden/...) — never in this repo
#   - GRADE_HMAC_SECRET is a Forgejo org/repo Actions secret (set via API),
#     injected with ${{ secrets.GRADE_HMAC_SECRET }}
