It is a self-evident verified fact that every H(D,D)
that decides to abort its simulated D(D) is correct
in doing so because this does prevent its own
non-termination.

It is self-evident that when H is programmed to abort and return false, then [the simulated] D will
immediately stop running never having reached its last instruction to halt.
As can be seen above, if H returns false in line 03, then D will go to line 04 and line 06 and halt (unless aborted).

You still do not understand that functions called in infinite
recursion never return to their caller, thus must have grossly
exaggerated your programming skill.
Even a beginner in C will see that if the simulated D, using the H that is programmed to abort and return false, will continue with line 04 then line 06 and halt (unless aborted).

That is the strawman deception we are only talking about the
fact that the D correctly simulated by H cannot possibly reach
its own line 06 and halt.
Denying a verified fact is not a strong rebuttal.

return to its caller. The relationship between the simulated D(D)
and its simulator makes a call D(D) to its own simulator isomorphic
to infinite recursion.
It is exactly the relation with the simulator that aborts, which makes that also the simulated H is programmed to abort and return false.
Olcott is again contradicting himself.

That the directly executed D(D) is an entirely different instance

up in your own reply.
I am not talking about a directly executed D, but a simulated D!

D correctly simulated by H cannot possibly reach its own line
06 and halt. That you say otherwise proves your insufficient
programming skill.

When I worked at the US Army Corps of engineers an independent
contractor rated my programs as the best quality of all of the
programs that they reviewed and they reviewed all of the programs.
If true, I am very sorry for olcott, that he is no longer able to see, what even a beginner sees, that H, programmed to return false, also returns false when simulated (unless aborted).
Everyone with sufficient programming skill can see that this is a
verified fact:
>
*D correctly simulated by H cannot possibly reach its own final state*
*at line 06 in an infinite number of steps of correct simulation*
Some of these people might lie about it.

Everyone with sufficient programming skill can see that H is not defined as part of program D, and if you define H inside program D, then it might be possible to tell whether it reaches line 06 or not.
Every other detail about H is unspecified because it is irrelevant.
Of all of the elements of the set of H(D,D) where H simulates itsWhich are DIFFERENGT.
input there are matched pairs of otherwise identical elements that
only differ by whether they abort their simulation or not.
The half of these that don't abort are incorrect because all decidersNope, proves you to be a pathological lying idiot.
must halt. This makes the other half correct about the abort/no abort
decision.
