The image every module in the scripted toolchain is compiled on top of is
registered as a module so the mesh can build, version and depend on it. It is
not one: nothing about it belongs on a machine. Assigning it succeeded, the
machine was sent a declaration containing nothing of it, and everything
reported success — the operator had said run this here and the mesh had agreed
to something it cannot do.
A module whose resources are worked out per node is asked about separately, so
it stays assignable, which is the point of it.
