After the build role moved to node-build-agent, nothing would hold it until build-agent is registered — and registering build-agent needs a build outcome that only the running builder could produce, bound as it was to the old seat by name. One binary, two roles: the seat a machine serves is the first its credential claims, as the mesh writes the claims beside the credential it issues (ADR 0159); the old builder keeps draining mesh-build-machine, a build-agent takes node-build-agent, and what each says about a build goes out as that seat's events, so an outcome is heard where the asker of that seat listens. A credential naming no claim serves the current role.
