Start in downloaders/collection.go at lines 165-170 and inspect the range loop together with the db.Client.Unscoped().Delete call. Check whether the reference to torrent can escape or be used by a goroutine, noting that the analyzer found no callgraph path. Done means classifying the finding as a bug, mitigated, or desirable behavior with supporting reasoning.
