Phase 1 of the DNS-redundancy cleanup (keep NetBird, collapse toward one
zone) — the safe, mesh-independent half:
- Every homelab LXC now resolves via Technitium (192.168.8.2). Fixed 8
boxes on a dead resolver (.180), the router (.1), or Tailscale MagicDNS
(100.100.100.100): 101,102,104,105,106,114,119,126.
- Removed the redundant /etc/hosts auth/mcp/secrets overrides (Technitium
returns identical-or-better answers); disabled hubris-hosts-override.
- Net effect: on-prem DNS (LXCs + household via Fritz!Box->Technitium) is
now NetBird-independent, so dropping the managed zone later can't break
on-LAN resolution. Phases 2-4 still pending.
Tailscale decommissioned (was legacy/being-phased-out):
- Removed from the 6 LXCs still running it (101,103,104,105,114,119):
logout, disable tailscaled, apt purge, state cleared.
- inventory.yaml: dropped tailscale from accepted + all mesh blocks;
regenerated hosts/*.yaml (also pruned orphan authentik/claudio-bot).
- Tightened secrets-issuance MESH_SUBNETS: removed the now-vestigial
Tailscale CGNAT range 100.64.0.0/10.
- Updated narrative docs (mesh, dns, network, README, AGENTS,
agent-enrollment, homelab-context, 105-apps, 107-dns).
Live infra changed on the fleet + Mac; this commit records the docs/inventory.
