Gauges are process-local, so a pod restart could silently drop an active
human_required signal before the vmalert hold window elapsed. Metrics move
to hermes_autotriage_metrics; every tick republishes gauges from stored
incident state, and an incident superseded by a newer successful build is
zeroed so the alert clears once the job is green again.
