 - Pi-hole runs on host port 53 - may conflict with systemd-resolved
-- Plex uses `/dev/dri` for GPU transcoding
+- Plex uses LinuxServer.io image (`lscr.io/linuxserver/plex`) with `/dev/dri` for GPU transcoding
+- Plex uses `VERSION=public` for auto-updates on container restart
 - Home Assistant runs privileged with host network for device access
-- Docker-GC runs daily at midnight with 7-day grace period
+- Task Scheduler runs scheduled maintenance:
+  - Daily at midnight: Docker cleanup (prune images/containers/volumes older than 7 days)
+  - Sunday at 3 AM: Plex restart (picks up VERSION=public updates)
