What the screen is
Desired-state rules for Radarr and Sonarr: conditions → arr-management actions (monitor / search, surgical tag add and remove, more later), kept continuously true so they catch items no matter how they arrived — Overseerr, a manual add, or a list import.
Unlike arr's own auto-tagging, tag removal here is surgical: a rule only touches the tag it names, never your collection or user tags.
Both are live — Radarr for movies and Sonarr for TV. A rule is one or the other, chosen when you make it, and the episode-monitoring settings further down this page are the Sonarr half. Save a rule, then Preview to see exactly what it would change — always a dry run. Apply writes to Radarr or Sonarr. Apply only runs on an enabled rule, and a run over its max-changes cap is NOT refused — it applies the first N and leaves the rest for the next pass, so a big rule drains over several runs instead of stopping dead. Apply all N in one pass is there if you want it done at once.
