A settings walk sends the layer alone, every build kept, and stops before a data move (issue 641, ADR 0344)

A judged send carries what waits on its machine, which would have released
builds held after a failed walk without a person's word. The settings walk
now keeps every build of its machine, refuses a send that would move a
running module's data, and never says delivered when it reached no machine.
