The provisioner makes the role and then the database; a poll that
waited for the first and checked the second once was racing the gap
between two statements, and lost it once, eighteen seconds into a run.
The cache test's provisioner could not resolve the store's name, which
usually means the store's container never registered it — and the
diagnostics showed only the provisioner's side of that conversation. A
grant that never arrives now prints the container states, the store's
log and the provisioner's, so the next failure names the half that
actually fell over.
