The worker keeps a step list — claimed by whom, asked which model, thinking, writing, each round's tokens, what it wrote, painted or not, checking the picture, the review's first finding, repairing, saving — and the model's latest sentence, and sends them with the heartbeat. The engine folds them into the snapshot as progress (phase, round, worker, start time, steps, said), for turns on the knot and, from its own phases, for turns run on the phone.
