Two properties the design claims and neither had been run.
A push to a machine that is switched off must not be lost — a machine is
disconnected as an ordinary situation, not an exception. The queue is
durable and the message persistent, which ought to be enough, but a lost
declaration is silent and "ought to be" is not a property. It waits: the
machine's host is stopped, the push happens, nothing changes on the
machine, and when it listens again it applies what it missed with no
second push and nobody saying anything.
Getting there found a real fault, now fixed in mesh-host and recorded as
04-ISSUES/011: the machine stopped at the first failing resource, so one
broken module blocked every module after it for ever. The evidence was
the broker's queues being EMPTY — the declaration had been delivered and
read.
And removal: two modules assigned, one unassigned, and the machine loses
exactly that one's file while keeping the other's — and keeps the store,
broker and control plane it raised from its own bundle, which the mesh
never declared and must never remove.
Two of my own traps recorded in the test, because both cost real time:
`pkill -f` matches the shell running it, which kills the connection
carrying the command and hangs the caller for ever; and a test that
depends on state another test left behind fails for a reason that has
nothing to do with what it claims.
