Function parked_on_look 

fn parked_on_look(task: &Task) -> bool

Whether a row is parked on the user’s own look - the verification wait the gate lands a user-bound completion on. The completion guard reads it: only the user’s approve completes such a row. A row merely BOUND by the gate, never parked on it, is work the caller may abandon.

The park belongs to the row’s OWN gate (#2423): a verification wait a row left behind while its gate was inherited from the epic stops counting, so a seat can complete it rather than being refused by a look nobody owes.
