What a restore does and does not undo

This is where restores surprise people. You have rewound Kustos's records, not your library.


Undone	Everything Kustos knew: which artwork it applied, enrolled sets, cleanup history, watch state it had recorded, settings changed since the snapshot
Not undone	Artwork already in Plex, files in your assets folder, anything the arrs did, anything deleted from disk

The practical consequence: Kustos will probably re-apply artwork after a restore. Its record of having dressed a title went back in time, the picture in Plex did not, so the next pass sees work to do and does it. That is expected and it settles after a pass or two. It is not a sign the restore failed.

If you restored specifically to undo a cleanup run, note that the files are still gone — a restore brings back the history of the deletion, not the media.
