System seats are mesh-* (one, mesh-wide) or node-* (one per node). Renamed: the-build-machine -> mesh-build-machine (+scope mesh), the-catalogue -> mesh-catalog, the-dns-port -> node-dns-resolver, the-intrusion-prevention -> node-intrusion-prevention, the-packet-filter -> node-packet-filter, the-resolver-configuration -> node-resolver-config, the-uplink -> node-uplink. Removed the-showcase from the set — it becomes the first module-defined seat. A manifest may declare its own seats (DefinesSeats); a claim is a system seat, a reserved mesh-*/node-* name the mesh does not define (refused), or a module-defined seat valid only when the manifest declares it. Deferred: the delivering registry seats (git, npm-package-registry, the-artifact-store) and the-private-network (a scope + server/client model change), per ADR 0121.
