Sharing after the flows were created left every flow between the owner and
the end of the list pointing at a library entry that did not exist yet. A node
that fails to load provides nothing, so one missing entry reported as inputs
nothing carries, in eighteen places.
The library is written *from* a node, so this is one throwaway flow that
carries both sources in and is deleted again — the entries outlive it. Order
stops mattering, which also covers the case that would have broken the
previous fix: two instances of one shared node inside a single flow.
Verified against the installation: nineteen flows, zero validation issues.
