Two halves of one gap the first build over the new bus met. The machine decided its bus from a variable its container never received, so the credential the mesh sealed to it went unread; a credential for the new bus names the bus by scheme and carries user, password and fingerprint beside the address, and that is enough to dial it, pinned. And the roles' work queues were raised with no holders, so the consumer a machine binds to take work was never created: the holders are read from the catalogue and the handover record, as the resolver reads them.
