These "models in our heads" are made of real world things, which have
qualities we directly apprehend in an infallible way, via the computational

You can doubt that the pencil out there is bent.  But you can't doubt that
your knowledge of the pencil is bent, nor can you doubt the yellowness
quality of your knowledge of that pencil.
The same as Descartes knew infallibly: "I think, therefore I am."

The left hemisphere of your brain knows, absolutely, that solipsism is
false, since it is directly aware of the knowledge in the other hemisphere.
Once we discover how to do this kind of computational binding to things
outside of our head (via neural ponytails, for example)  we will be able to
falsify solipsism.
Or possibly, our failure to be able to do that, could verify solipsism.
