Collections

For a rule that adds a collection's missing films, Kustos adds them itself — and Radarr's own collection monitoring has to be off for those collections, or the Kustos-side filters do nothing.

That rule is stated in full, with the trade-off, under Collections → Adding missing members in the main wiki, and again as a troubleshooting entry. It is not repeated here: one home per rule, so a change to it only has to be made once.
