 - **Mediaopslag**: HostPath `/datadisk` gemount op `/datadisk` (voor films in `/datadisk/htpc/Films` en downloads in `/datadisk/upload`).
 - **Netwerk & Ingress**: Luistert op poort `7878` (zowel via ClusterIP als HostPort `7878` op `10.2.0.4`), waardoor de bestaande Apache reverse proxy rule (`ProxyPass /radarr http://127.0.0.1:7878/radarr`) naadloos blijft functioneren.

+De BitTorrent daemon (`transmission`) draait als pod in de `htpc` namespace:
+
+- **Dataopslag**: PersistentVolumeClaim `transmission-config` (10Gi, `local-path` op `/datadisk/infra/pv`), gemigreerd vanuit `/var/www/.config/transmission-daemon` met behoud van alle torrents, resume-bestanden en instellingen.
+- **Mediaopslag**: HostPath `/datadisk` en `/mnt/mp3` zodat `/datadisk/upload/finished` en `/datadisk/upload/incomplete` identiek zijn voor Transmission, Radarr, Sonarr en Lidarr.
+- **Netwerk**: Web UI / RPC op poort `9091` (ClusterIP + HostPort `9091`) en BitTorrent peer-poort `53662` (TCP & UDP, ClusterIP + HostPort `53662`).
