+# =============================================================================
+# nomad/jobs/forgejo.hcl — Forgejo git server (Nomad service job)
+#
+# Part of the Nomad+Vault migration (S1.1, issue #840). First jobspec to
+# land under nomad/jobs/ — proves the docker driver + host_volume plumbing
+# from Step 0 (client.hcl) by running a real factory service.
+#
+# Host_volume contract:
+#   This job mounts the `forgejo-data` host_volume declared in
+#   nomad/client.hcl. That volume is backed by /srv/disinto/forgejo-data on
+#   the factory box, created by lib/init/nomad/cluster-up.sh before any job
+#   references it. Keep the `source = "forgejo-data"` below in sync with the
+#   host_volume stanza in client.hcl — drift = scheduling failures.
+#
+# No Vault integration yet — Step 2 (#...) templates in OAuth secrets and
+# replaces the inline FORGEJO__oauth2__* bits. The env vars below are the
+# subset of docker-compose.yml's forgejo service that does NOT depend on
+# secrets: DB type, public URL, install lock, registration lockdown, webhook
+# allow-list. OAuth app registration lands later, per-service.
+#
+# Not the runtime yet: docker-compose.yml is still the factory's live stack
+# until cutover. This file exists so CI can validate it and S1.3 can wire
+# `disinto init --backend=nomad --with forgejo` to `nomad job run` it.
