-| Technitium primary source node | PD (`10.5.30.8` via `technitium-pilot` macvlan stack) | 53 / 5380 | ⚠️ Container is running, but this pass did not directly verify the admin HTTP path because the service is not host-published and simple LAN-side `:5380` probes did not answer |
-| Nebula Sync | PD | container-only | ⚠️ Container is present but currently reports `unhealthy`; re-check before treating old Pi-hole sync as healthy |
+| Technitium primary source node | PD (`10.5.30.8` via `technitium-pilot` macvlan stack) | 53 / 5380 | ✅ Active source of truth; PD root cron runs `technitium-pilot/bin/sync_backup_nodes.sh` every 15 minutes, and recent logs show successful sync + verification of Nomad (`10.5.30.9`) and Serenity (`10.5.30.10`) |
+| Nebula Sync | PD | legacy Pi-hole-only helper | ⚠️ Not part of the active Technitium design. A stale `nebula-sync` container still exists in the old Pi-hole stack and is currently `unhealthy`; retire it with the remaining Pi-hole leftovers instead of treating it as DNS source-of-truth |
