The gate judged a module by what the mesh saw from outside, so a container that crash-looped after it applied passed it. Each machine's node-engine now states the health of every long-running resource it runs; the controller keeps the newest statement per machine, raises module.<module>.<machine>.unhealthy on the second statement in a row, clears it on the first that does not say it, and the gate passes a module only when every long-running resource of it is stated healthy since the send. An engine that states nothing is judged as before.
