| `.dashboard-last-run` | Epoch timestamp of the last timer execution. |
| `.dashboard-lock` | PID lock file preventing concurrent timer runs. |
| `.dashboard-pending` | Changes held back when Apply on Save is disabled; flushed to `.dashboard-queue` when Apply Now is clicked. |
| `.status` | JSON health check results written by `core.py --apply`, `core.py --status`, and the dashboard timer. Read by the dashboard to display problem alerts. |
| `.dns-metrics` | Cumulative lifetime DNS metrics across all VLAN instances. Created and updated each time `--view-metrics` is run. |
| `.ddns-last-ip-*` | Cached public IP per DDNS provider. Managed by `ddns.py`. |
| `.ddns-last-service` | Tracks IP-check service rotation. Managed by `ddns.py`. |
