The first fix continued past every failure, and the next lab run failed
at the bootstrap: the store did not answer in three minutes and then said
"the database system is shutting down". Carrying on past the readiness
gate had started the broker and the control plane against a machine that
was not ready, and on a small machine that is how a database still
initialising has its memory taken away.
An action is the only shape whose purpose is to make something true
BEFORE the next thing needs it, which is why it is the only one with a
verify. So a failed action stops what follows and nothing else does —
which fixes both this and the hostage problem the issue was opened for.
