It became clear that a secondary system of connections must be added,
running top-down from a global model context, and thus contrary to the
regular orientation of the node network, which connects upwards from
predecessor to successor, in accordance with the pull principle.
If we accept this wiring as part of the primary structure, it can be
established immediately while building the nodes, thus adding a preconfigured
''pattern of Buffer Descriptors'' to each node, since there is no further
''moving part'' — beyond the wiring to the `BufferProvider`, which thus
becomes part of a global `ModelContext`
As an immediate consequence, the storage for this configuraion should
also be switched to `lib::Several` and handled similar to the primary
node wiring in the Builder...
