The controller's healer H1 answers a send that went unreported by asking the
machine first: a report lost on its way (issue 264) needs no second send. The
node-engine now hears mesh.node.<self>.ask.report on core NATS and enqueues a
reconcile whose account is said whether or not it is news; a delivery waiting
meanwhile is applied and reported instead. The answer is an ordinary report on
its own subject, so the node publishes nothing new and answers nobody's inbox.
The genesis lock grants the controller the healer-acted seat event, which it
now composes; the genesis test in mesh-controller holds the two equal.
