There is no way that DDD simulated by HHH (according
to the semantics of the C programming language)
can possibly reach its own "return" statement final
halt state.

I don't say that the decider needs to simulate the input to completion, but that it needs to be able to actually PROVE that if this exact input WAS given to a correct simultor (which won't be itself, since it isn't doing the complete simulation) will run for an unbounded number of steps.

And HHH does not do that. The input specifies a halting program, because it includes the abort code.

That does have an effect on DDD emulated by HHH according
to the semantics of the x86 language stopping running.
It has no effect on this DDD every reaching its final halt
state. I have corrected your error on this too many times
you don't seem to want an honest dialogue.

 100% *complete proof is provided above*
That you don't have sufficient technical
skill to see that this is complete proof
is not my mistake.

You fail to see that it is not a 100% proof. It is incomplete. The code has a call to 000015d2 , but you do not show the code there. we know that this code is the HHH that aborts and halts, so a correct simulation will then reach 0000219f and then reach the final halt state.
We also know that HHH fails to reach that final halt state, because of a premature abort. A proof with so many errors, is far from 100%.
You can close your eyes for these errors and pretend that they do not exists, but that would be childish.

 

It is a pity that you ignore or do not understand the corrections that have been pointed out to you. Not understanding something is not stupid, but resistance against learning from errors is.

 DDD correctly simulated by HHH calls HHH(DDD)
that simulates DDD that calls HHH(DDD)

Using falsehoods to prove your case is not convincing. We know that HHH aborts before 6 cycles have been simulated.

 That you cannot see that this is the behavior
that the input to HHH(DDD) specifies is your
own lack of technical skill.

That you do not even understand your own code, where HHH aborts after a few cycles, does not change the fact that the real behaviour specified is a halting program. But as usual, you and HHH close your eyes and pretend that what you do not see does not exist.

 *Maybe it is time to reveal credentials*
I have taken all but one of the courses
for a computer science degree and been a
C++ software engineer for two decades.
Mensa scored my IQ is in the top 3%.
 

We have pointed out already many times that this cannot be the whole input. At 0000219a there is a call to 000015d2 , but the code at 000015d2 is not specified.

 https://liarparadox.org/HHH(DDD)_Full_Trace.pdf
Because of the required cooperative multi-tasking
it is a little too difficult to see which the
actual trace.

Even that trace proves that HHH aborts before it can see the full behaviour specified in the input. Then it closes it eyes and pretends that what it does not see does not exist.

 

We have to take it from another source, your Halt7.c. There we see that HHH is a function that returns with a value 0 with this input. So, a correct simulation will then continue at 0000219f

 DDD simulated by HHH according to the semantics of the x86
language cannot possibly ever get there even of your lack
of sufficient technical skill tells you so.
 *Feel free to dig through this full trace and see*
https://liarparadox.org/HHH(DDD)_Full_Trace.pdf
 

with this value and even a beginner sees that the simulation will then reach a natural end.

 *DDD simulated by HHH NEVER REACHES ITS FINAL HALT STATE*
DDD correctly simulated by HHH calls HHH(DDD)
that simulates DDD that calls HHH(DDD)
that simulates DDD that calls HHH(DDD)
that simulates DDD that calls HHH(DDD)
that simulates DDD that calls HHH(DDD)
that simulates DDD that calls HHH(DDD)
that simulates DDD that calls HHH(DDD)...

Again the same falsehood. HHH aborts way before simulating 6 cycles.
Using falsehoods to prove your case does not make your case any stronger.

 

This is the full specification of the input.
This is also proven when exactly the same input is used in direct execution, or by world-class simulators, even by HHH1.
So, the following still holds:

But HHH gives up before it reaches that part of the specification and the final halt state.

If HHH does not see the full specification, it does not change the specification. It only illustrates the failure of the simulation to complete.
There is nothing wrong with aborting a simulation, because it is known that simulation is not always the correct tool to determine halting/ non- halting behaviour. In such cases other tools are needed to determine halting/non-halting behaviour.
