A have in phase waiting-yes keeps the build that still runs and that build's health (the node-engine writes the running fingerprint and composition, and its check's health), and that build serves the bus state. So the bus-state rule no longer holds a consumer that needs none of the newer build's forms: live, zfs on ace waited while nats on novox waited for a yes with its old build running. A consumer of a form only the newer build reads still waits by its kind-4 edge (§50), unchanged.
