"description": "The swarm's secret store. Two things to know before editing: the metric prefix is vault_, not openbao_ — the fork kept upstream's names, and a panel built on the name you would guess renders perfectly and shows nothing. And a SEALED store emits almost nothing: only the top row works before an operator has run `bao operator init`, everything below it is empty until then and that is the expected reading, not a broken query. Targets are labelled service.name, NOT job; there is no job label in this store. Counters are counts over the dashboard range rather than per-second rates, because a store this quiet rates to exactly zero.",
