While the mesh-delivery seat has a holder on record, a merge that moves no core module opens its walk and asks nothing until mesh-delivery or a person says go; nothing of it is registered before its turn, so no other send carries it. The controller keeps the planner, the gate, sending and the walk, and gains the verbs the owner asks with: delivery-plan, -order, -check (a group composed as one future state), deliver, delivery-stop, delivery-walks; every walk kept is said as plan-moved.
