The agent account a machine names comes from placement; the engine's verdicts on it from its health report
(mesh-host.health, NodeHealth.Root and Contract); whether that verdict is on now from the watchman's presence, since
the report is written on a change only. The judgement is the controller's: no report, not heard, an engine older than
the judging, no verdict, or any verdict not healthy is not confined; a verdict waiting for the setuid search is quiet
for twelve hours from when this self-check first saw it waiting. machine.<node>.agent-root, urgent, the controller's
words. Rows in TestTheBusProbes; pins mesh-sdk f3677eb.
