+**Who claimed a turn is now recorded, and so is who did not** (V-564, umbrella
+V-558). Arbitration between the claimants on the utterance stream is order,
+hardcoded in the pre-route resolver ladder, in `buildRouter` and in
+`querySources`. `internal/decision` records one `Record` per turn: every
+claimant, what it would have made the turn, the score it reported, and whether
+it won, declined, lost on score, was thinned by a gate or was **never asked**.
+The record rides the context, the same seam `querysource.go` uses, so a claim
+site cannot change a route and a context with no record costs nothing. It is
+installed in `runTurn`, so the mic, telegram and the web all leave the same
+trail. Storage is a 25-turn in-memory ring on the handler (`decision.Ring`),
+read over `ipc.TurnDecisions` and rendered as the second table on `/trace`.
+Nothing persists: a turn record is read minutes later or never, and his words do
+not belong in a table that outlives the diagnosis. Adding a rung to the ladder
+in `runTurn` means adding its name to `preRouteLadder` in
+`cmd/mavend/decisiontrace.go`, or that rung is silently missing from the record.
