It has been proved that HHH cannot possibly correctly simulate itself.

 That is false and you know it. That might not be a
flat out lie as it is an sloppy use of language.
 HHH does correctly simulate itself simulating DDD one time,
then it stops correctly simulating itself because this criteria
is met:
      HHH correctly simulates its input DDD until HHH
     correctly determines that its simulated DDD would
     never stop running unless aborted
 https://liarparadox.org/HHH(DDD)_Full_Trace.pdf
 

So, the above code shows that the incorrect simulation of DDD by HHH is unable to reach the 'ret' instruction, because it either never aborts, or aborts one cycle too soon, when the simulated HHH is only one cycle from its own abort and return and then the return of DDD would follow.

It has been pointed out many times that this is sloppy use of language.
HHH *does* abort, so the 'unless aborted' does not make sense.
Since HHH *does* abort, its simulation does not need to be aborted (as a correct simulation by another simulator shows).
HHH is incorrect when it determines that the simulation of an aborting self would never stop. If not aborted, the simulated HHH would abort, because that is how it is programmed. But the simulating HHH does not see that, because it aborts one cycle too soon.
The reason is that a simulator cannot possible correctly simulate itself.
I hope you finally see it.
The wording 'would never stop running unless aborted' suggests that there is a possibility that the simulated HHH would not abort, but that is just an irrelevant dream, because this HHH is programmed to abort and there is no other HHH in this simulation.
