the ring reads out over ipc as turn decisions (V-564)

Same shape as TickTrace and RecentEvents: a bounded daemon ring, so the store
adapter refuses rather than pretending a table exists. No voice wiring means an
empty list and not an error, because a box with no voice path has had no turns
to arbitrate.
