# public git hosting | egress internet | repos+DB on Longhorn (irreplaceable, DR-critical) | auth oidc.
# Bootstrapping-critical: self-hosts the platform's GitOps source + CI/CD, onboarded EARLY (docs/13
# "Gitea is bootstrapping-critical", WS-APPS step 2, right after PiHole). A cluster loss would take its
# own git host with it, so repos/DB are backed up off-cluster + mirrored (R-STATE-03).
# Single-container Gitea with the built-in SQLite datastore is sufficient at home scale; the repos and
# DB live on one Longhorn PVC (/data), so no external PostgreSQL is required for this onboarding.
# Validates against schemas/servicedefinition.schema.json.
