  Each plan updates an inventory group's hosts once a week, one host at a time. A host reboots
  only when its update needs it, unless the plan says otherwise; a swarm node is drained first
  and made active again after. The next host starts once the last is back in service. A failure
  stops the run, and the host's <em>Maintenance failed</em> figure can drive an alert rule.
