A daily job sweeps the changes other people merged, verifies the claims, and writes a report. It used to also interview me about the decisions only I can make. That stopped working once the sweep started routing to whichever engine had headroom, because parking a session on an open question is a feature of only one of them. The two phases are now separate jobs joined by a durable queue row. The sweep finishes and files its questions; a second timer picks them up and starts the interview. Each row is claimed with one atomic update, so two ticks cannot start two interviews on the same run, and a tick that lost its lease cannot overwrite the one that now owns the row.
