A server-started stop for an engine that exits on its own: no request,
no confirmation; it closes admission and supersedes the current stop
(H17), but refuses stop-owned under a force stop or another engine
exit. The binding follows it like a force stop at startStop,
advance-stop and confirm-stopped, and its proof needs a member.
Dispatched or acknowledged input goes delivery-unknown; working input
keeps its state. Five lifecycle sequences and two shape cases.
