### Technitium Backup Resolver
- Live stack path: `/opt/technitium-nomad`
- Resolver bind IP: `10.5.30.9`
- Role: active DHCP-advertised backup Technitium resolver for the homelab
- Config is refreshed from PD's live Technitium directory by the PD-side sync runner every 15 minutes
- Same-host checks from NOMAD to `10.5.30.9` are unreliable because the resolver sits behind macvlan networking; verify from another LAN peer instead

## DNS Role
- Primary Technitium source-of-truth node binds `10.5.30.8` via the `technitium-pilot` stack
- Root cron runs `/mnt/docker-ssd/docker/compose/technitium-pilot/bin/sync_backup_nodes.sh` every 15 minutes to push the live Technitium config to the backup nodes on N.O.M.A.D. (`10.5.30.9`) and Serenity (`10.5.30.10`)

- External fallback `9.9.9.9` protects public DNS continuity, but authoritative `home.paccoco.com` answers still depend on at least one Technitium node being up

### Technitium Backup Resolver
Serenity hosts the secondary backup Technitium node on `10.5.30.10`.

## Notes
- No GPU; reranker uses CPU-only TEI image
