- 3-node HA cluster (k3s v1.36.3+k3s1, embedded etcd) on Hetzner
- Netbird VPN mesh (wt0) for all cluster traffic
- Longhorn distributed storage (2 replicas, /var/lib/longhorn/)
- Traefik ingress (3 replicas, LoadBalancer on all node IPs)
- cert-manager with Let's Encrypt (auto-renewing TLS)
- Gitea (git + container registry) with SQLite on Longhorn
- 4 migrated workloads: wolsey, school-games (3 variants), randomly
- All HelmCharts and workload manifests as YAML
