ZONE_
The default priority for a guided path transporter re-attempting its claim on a zone that has just been released. The default is KSLEvent.HIGH_PRIORITY - 1.
The value is chosen relative to two neighbours. It is a higher priority than MOVE_PRIORITY so that a woken transporter settles its claim before other transporters finish traversals at the same instant, which is what keeps the order in which a zone is freed and re-claimed observable and reproducible. It is a lower priority than RESUME_PRIORITY so that it never preempts a process resumption already in flight. It is one step ahead of SEIZE_PRIORITY so that space is settled before resource seizes at the same instant read transporter state.
