/watch-list/cvr/{cvr}

Hot-path check used by the company-page "Følg" button.

The company page probes this for every logged-in visitor. Until 2026-09-24 it sat behind the Pro gate, so every Basic page view recorded a "notifications" paywall hit and fed the nudge mails: the hit counts measured page views, not follow attempts. Any tier that may hold watchers reads its own state here, and no hit is recorded.

Returns {watching: bool, watcher: Watcher | null}. watcher is the single-CVR Watcher targeting this CVR (if any), or null. Multi-CVR Watchers (e.g. an API-managed bulk filter) count toward watching=true but watcher will still be null in that case — the per-company edit/delete UI only operates on per-CVR Watchers.
