This is why HHH does not satisfy "H correctly determines that its

decision on anything else than what its actual input actually
specifies it does not decide correctly.

Right.  It seems to be a recent innovation in PO's wording that he has
started using the phrase "..bases its decision on a different *HHH/DDD
pair* ..".

This, the simulator. The input still calls the same real aborting HHH.

If H always reports on the behavior of its simulated input after it

be halting.

Yes, that is why H is wrong.

Just no.

H does stop running when simulated without aborting, because it aborts.

When the hypothetical H never aborts its simulated D then:
(a) Simulated D  NEVER HALTS
(b) Executed D() NEVER HALTS
(c) Executed H() NEVER HALTS
(d) Everything that H calls NEVER HALTS

HHH is required to report, that is why it
must always report on the behavior of the
hypothetical H/D pair and not the actual
behavior of the actual H/D pair for every
non-terminating input.

Every decider is required to report. But your (c) above prevents the
hypothetical H from reporting. Therefore the hypothetical H is not a
decider.

People only glance at a couple of words that I say
then artificially contrive a fake rebuttal.

 We use the same criteria. We see that there is no correct simulation and that H does not correctly determine that its simulated D would never stop running. In fact the input specified to H contains code to abort, so a simulation of this input without abort would lead to a natural halt.
 

That is merely your lack sufficient software skills.
(a) The outermost (directly executed) HHH sees its
abort criteria met one whole execution trace before
the next inner one.
(b) Every instance of HHH is the same machine code at
the same address thus each HHH has the same behavior.
(c) Unless the outer HHH aborts its simulation then
none of them do because they all have the same machine
code.
