DDD is correctly emulated by HHH which calls an

Once aborted the DDD emulated by HHH immediately stops.

I understand it, but that does not contradict that the abort is one cycle too soon, which makes it incorrect.

I did not disagree with myself. It is only you inability to understand simple facts that :
It is not: Either aborting or not-aborting is incorrect,
but: Both aborting and not-aborting are incorrect.
Therefore, proving that not-aborting is incorrect does not prove that aborting is correct.
You never found an error in this reasoning, but only repeat that not-aborting is incorrect.

It must abort to terminate the loop if the simulated HHH would not terminate, but this simulated HHH does return after N+1 cycles and therefore DDD will return, so here no abort is needed.
Abort is only needed if simulating an infinite recursion, not a N-cycle recursion.

If simulating halt decider H correctly simulates its input D
until H correctly determines that its simulated D would never
stop running unless aborted then
But it does not correctly determine that the simulated D would never stop running. Your seem to be incompetent to understand that a C program, or x86 language that specifies N cycles of recursive simulation does stop after those cycles are all simulated, even when simulated correctly.
void Infinite_Loop()
{
HERE: goto HERE;
}
void Infinite_Recursion()
{
Infinite_Recursion();
}
void DDD()
{
HHH(DDD);
}
int main()
{
HHH(Infinite_Loop);
HHH(Infinite_Recursion);
HHH(DDD);
}
HHH is correct to abort all three.
void Finite_Recursion (nit N) {
if (N > 0) Finite_Recursion (N - 1);
}
HEH, aborting after N cycles of recursive simulation, when simulating itself, is equivalent to Finite_Recursion, not to Infinite_Recursion.
