How a request gets in: everything internal terminates at one reverse proxy (WolfProxy on aragorn); the only public door is NetBird's traefik. DNS is authoritative on Technitium with the gateway ad-filtering in front.
Fabric: 20 G bond (vmbr1, jumbo 9000) carries VLAN 4 + storage; mgmt vmbr0 2.5 G (10 G on aragorn); Thunderbolt mesh for Ceph.
client → EFG ad-filter → Technitium 10.1.4.53 (pippin, primary) / .54 (merry, secondary) → 1.1.1.1 / 1.0.0.1
Apps run host-native Docker (visible cluster-wide in WolfStack); infrastructure with its own blast radius runs in LXCs. Stopped guests are kept deliberately as revert paths.
Three tiers: bulk media on one big ZFS pool served over NFS, databases on triple-replicated Ceph block, shared configs on CephFS. Everything stateful is backed up nightly to a standalone PBS box.
