Give the uplink seat its verbs, optional until its holders serve them (hq ADR 0241)
What a machine resolves through and over which links had no tool: the
resolver file and its writer, and each link with its routes and resolvers,
are now verbs of node-uplink, the same whatever manages the network. Marked
optional (Verb.Optional), so today's holders still hold the seat until both
serve them; read back from the store's row they stay optional.
