Bridges help users connect to external content (RSS, ActivityPub) but are not real Org Social accounts. They no longer appear in /feeds/, cannot be registered via POST, are skipped by both feed discovery tasks, and do not count in /stats/. A data migration removes bridge URLs already registered as feeds.
