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. A verb
required at once would refuse every holder before the catalogue could serve
it, and a stored one would be required by an older controller, so it is
staged: promised and routed, never stored, and not yet a condition of
holding.
