A 'pure simulation' of its inputs is NOT what you describe below. A pure
simulation of P(P) behaves *identically* to P(P). They both halt (see
below for explanation).

When run independently H(P,P) isn't even being computed. If you are
referring to the *internal* copy of H contained in P, then that
*incorrectly* decided that its input never halts.

Here you're just being idiotic. This error has been pointed out to you
so many times that you cannot possibly not see it by now.
A 'pure simulation' of P(P) involves passing the description of P, P to
some pure simulator. It DOES NOT involve taking P and changing its
internal code so that its copy of H acts as a simulator rather than a
halt decider.
If you do that you are *not* simulating the input which you gave to H(P,
P). You are simulating some entirely different computation (call it
PBroken) whose halting status has absolutely no bearing on the
computation under consideration.
When S is a pure simulator, S(P, P) completes its simulation and that
simulation reaches one of its final states. IOW, it halts, just like
P(P) halts when run as an independent computation.
S(PBroken, PBroken) won't halt any more than PBroken(PBroken) will, but
that is an entirely different computation from the one which H is being
asked about. Talking about it has no relevance to anything.
