 * Seeds `ref.announced` with the resolved prior (pendingness preserved — a suspend before the
 * receipt then mirrors the honest state) and returns the frame BODY to deliver, or undefined when
 * the announced view already matches (or the lane has nothing to say this leg). Tombstone kinds
 * fire on the availability FLIP EDGE only: with no prior view at all there is nothing to disown —
