 Empirical proofs can be ostensive.

But I prefer not using "proof" for that. It can only be misleading when we do applied logic. I prefer to call that "empirical evidences".

 So I think the two kinds of 'proof' have little in common.

Almost nothing indeed.

Mathematical proofs are about transforming one set of propositions into others. They are relevant to empirical propositions only insofar as there is an interpretation that maps the axioms to facts.

I agree. Axioms comes from empirical evidences. The consequences of the axioms can be used to test the theory, and refute it, but will never prove it to be true.

You should write, "...but will never empirically evidence it."   :-)
