makes it impossible for H to see the behaviour of P(D).
The behaviour of P(D) does not change, but H does not see it.
 H MUST REPORT ON THE BEHAVIOR THAT IT DOES SEE
H has the whole P tape and the whole D tape at its disposal. There is nothing it can't inspect.
Not being able to see how P behaves in simulation is no excuse for getting the answer wrong. If because of limitations in H it fails to spot behaviour that would have changed its report on P(D), that just means that H is broken.
But don't bother trying to fix it. Turing has already proved that you can't.
