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
# thermograph-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. Runs on the `docker` label (the always-on Swarm-hosted runner
# deploy/forgejo/ stood up).
#
# Targets PROD via the PROD_SSH_* secrets (prod = 169.58.46.181, `agent` user,
# in the docker group so no sudo needed; /etc/thermograph.env is agent-readable).
# These are the same secrets deploy-prod.yml uses for the release->prod deploy --
# NOT the SSH_* secrets, which point at BETA (deploy.yml's `main`->beta path). An
# earlier revision reused SSH_* here, so the "prod" backup was silently dumping
# beta; prod itself had no backup at all. The prod database is the one that must
# be backed up, so both jobs use PROD_SSH_*.

# Monorepo port: the compose file now lives under infra/ of the host's
# /opt/thermograph monorepo checkout, so every docker-compose invocation cd's
# into /opt/thermograph/infra (compose also pins `name: thermograph` so the
# project name no longer depends on the directory). Everything else unchanged.
