A controller that asked node-build-agent from its first run would queue every build where nothing pulls, and the build that registers build-agent — the first holder — would be among them. So the role is chosen at ask time from the catalogue: the current role when any assigned module claims it, the retired one while only the builder does, the current one when neither. Outcomes are followed on both seats, the controller may publish to both, and a build's log is read under whichever role did it; a machine on the retired role is proven on the bus to take that role's asks. The switch order is written where the role is named, and the retired half is marked for removal with the seat row.
