The bed resolves an artifact the way the builder would

It pre-builds these images and stocks them, which is the lab standing in for the
builder — so it must do what the builder does and replace the artifact with the
reference the machine holds. Without it the unresolved field travels to the
machine and the whole declaration is refused.
