Both media servers read a Kodi-format sidecar (movie.nfo / tvshow.nfo / episode.nfo) only when it sits next to the media file, and the library lives on the RAID6 array, deliberately mounted read-only for every container and slow to seek for a thousand tiny XML reads. So neither server binds the array any more: both bind /mnt/media, an OverlayFS merge of the array (lowerdir, never written) with /var/lib/media-meta on the NVMe (upperdir, where every write lands). Jellyfin binds the view rw at /data and is the fleet's only metadata writer; Plex binds it ro at /mnt/entropy, the container path its own database already recorded, so only the host side of that bind moved and its library paths keep resolving. scripts/media-view.sh plans, installs, verifies, reports and reaps the view. It refuses to mount over an unmounted array, refuses an upper layer on rotational storage, and refuses a non-root install. deploy-remote.sh raises the view before it restarts either media server, both units carry ConditionPathIsMountPoint=/mnt/media so a missing view skips the start instead of letting a scan clear the library database, and the planner routes the installer and dankserver/host/** to the jellyfin+plex pair. tests/media_overlay.bats (11 seams) pins the resolved shape, both refusals, the two binds and their guard, the deployer's ordering, the planner mapping, and the reap behaviour against a fixture (ghosts listed, then moved to the SSD trash -- files that exist only above are sidecars, not ghosts, so only directories are candidates).
