network.machine-roles@1: the catalogue of machine roles (plan L34, step M4). A product declares a role — a name, what it installs on the machine and what the hub shows — and the Link turns it on at its next check-in. The first roles are Codes' worker, Desks' host, AI's local models and Bot's robot. A role outside this catalogue is refused (network.machine-roles-put@1).
