Arbitration between the claimants on the utterance stream is order, hardcoded
in three places, and a log that names the winner cannot explain a loss. The new
package holds one record per turn: who claimed, what it would have made the
turn, the score it reported, and why the rest did not get it. Being explicit
that a claimant was never asked is the point: that silence is what the
hardcoded ordering hides.
The record rides the context, the seam querysource.go already uses, so no claim
site can change a route and a context with no record costs nothing. The ring is
memory and bounded: a turn record is read minutes later or never, and his words
do not belong in a table that outlives the diagnosis.
