QUEUE row 15, MVP iteration 1 after the Sage pilot. rest.react is best
effort (2xx true, anything else false, never throws); the connector reacts
at admission before the engine runs and records the outcome in the turn
record as receipt. Drops and refusals get no reaction. Suite 28/28, 90
node tests.
