Until part markers, a PC reported exactly one backup kind and "newest revision
wins" was the same thing as the truth. A marker bay reports two: ntlars for the
machine's DNC settings, partmarker for the controller's patterns.
With newest-wins, the daily ntlars post keeps the badge green while the marker
backup has been failing for a month. The failure shows only on that marker's
asset page, which is not where anyone looks to find out something stopped - and
"is this still being checked" is the one question this badge exists to answer.
So a host is green only when everything it backs up is current, and the badge
names the kind that is not. Freshest revision per kind first, because
lastseenat only ever moves on the newest revision of a chain; judging every row
would report a healthy, frequently changing config as permanently stale.
Known consequence, and the right direction to err: a device retired from a PC
leaves its last revision behind, so that host stays stale until the revision is
pruned. It complains about a backup that genuinely is not running rather than
staying quiet about one.
The dashboard card needed no change - it already lists every stale chain
independently, so a stale partmarker chain was never hidden there.
