+  # alert-monitor.yml and issue-fix.yml, which still sit on an older one. That is
+  # staleness in those four, not a deliberate split here — everything should be on
+  # the newest dated tag. They are not bumped here because none of them are
+  # triggered by this PR, so it would ship untested changes under cover of a green
+  # run that never touched them. Tracked in #461.
