 ## Detection Rules
 
-- Check only finished, current, main-frame HTTP(S) document navigations after a grace period.
+- Check only finished, current, main-frame HTTP(S) document navigations after a grace period. A failure means the extension is loaded and the dashboard remains `.waiting`; `cpmStage` is diagnostic data, not part of detection.
 - A redirected restored-page navigation remains classified as session restoration.
 - After restoration, any independent eligible document navigation can be the next attempt: reload, typed URL, link, new-tab navigation, or a real back/forward load.
 - Redirects do not count separately. Same-document, failed, non-HTTP(S), and BFCache navigations do not count when CPM is not expected to initialize again.
