  # registry-private removed in Phase 4 of forgejo-registry-consolidation
  # 2026-05-07. The /v2/ private registry has migrated to Forgejo at
  # forgejo.viktorbarzin.me/viktor/<image>. Pull-through caches for upstream
  # registries (dockerhub, ghcr, quay, k8s, kyverno) stay on this VM.
  # Manual decommission step on the live VM:
  #   ssh root@10.0.20.10 'cd /opt/registry && docker compose up -d --remove-orphans'
  # …and after 1 week of no incidents, `rm -rf /opt/registry/data/private/`.
