name: Ops cron (backup + IndexNow)

# Scheduled operational jobs that don't belong in the app's own worker-tier
# scheduler (notifications/scheduler.py, Track A chunk 5) because they're
# infra/ops concerns rather than app-domain background work -- see the job
# classification table in
# docs/architecture/repo-topology-and-infrastructure.md §7.
#
# Both jobs SSH into the prod host and run inside the already-running compose
# stack (docker compose exec), the same way deploy.sh already runs its own
# post-deploy IndexNow ping -- no new network exposure, no separate dependency
# install. Needs a runner registered with the `thermograph` label (Track B step
# 5) and the same SSH secrets deploy.yml uses (SSH_HOST/SSH_USER/SSH_KEY/
# SSH_PORT) to reach the prod host.
