Serve the uplink seat's verbs from both of its holders (hq ADR 0241)

What a machine resolves through had no tool: the resolver file and who
wrote it, and every link with its default route and the resolvers its
manager knows. Each holder serves the same two node-uplink verbs; the
reading is one text carried by both, held to it by a test, and only
asking the manager for a link's names is each holder's own.
