 *It is a basic fact that DDD emulated by HHH according to*

*running unless aborted* (out of memory error excluded)

 But it can't emulate DDD correctly past 4 instructions, since the 5th instruciton to emulate doesn't exist.
 And, you can't include the memory that holds HHH, as you mention HHHn below, so that changes, but DDD, so the input doesn't and thus is CAN'T be part of the input.
 

 X = DDD emulated by HHH∞ according to the semantics of the x86 language
Y = HHH∞ never aborts its emulation of DDD
Z = DDD never stops running
 The above claim boils down to this: (X ∧ Y) ↔ Z

 And neither X or Y are possible.
 

 x86utm takes the compiled Halt7.obj file of this c program
https://github.com/plolcott/x86utm/blob/master/Halt7.c
Thus making all of the code of HHH directly available to
DDD and itself. HHH emulates itself emulating DDD.

 Which is irrelevent and a LIE as if HHHn is part of the input, that input needs to be DDDn
 And, in fact,
 Since, you have just explicitly introduced that all of HHHn is available to HHHn when it emulates its input, that DDD must actually be DDDn as it changes.
 Thus, your ACTUAL claim needs to be more like:
 X = DDD∞ emulated by HHH∞ according to the semantics of the x86 language
Y = HHH∞ never aborts its emulation of DDD∞
Z = DDD∞ never stops running
 The above claim boils down to this: (X ∧ Y) ↔ Z
 

 Yes that is correct.

 So, you only prove that the DDD∞ that calls the HHH∞ is non-halting.
  Not any of the other DDDn
 

 

Your problem is that for any other DDDn / HHHn, you don't have Y so you don't have Z.
 

 void EEE()
{
   HERE: goto HERE;
}
 HHHn correctly predicts the behavior of DDD the same
way that HHHn correctly predicts the behavior of EEE.
 

 Nope, HHHn can form a valid inductive proof of the input.
 

 

It can't for DDDn, since when we move to HHHn+1 we no longer have DDDn but DDDn+1, which is a different input.
 

 You already agreed that (X ∧ Y) ↔ Z is correct.
Did you do an infinite trace in your mind?

 But only for DDD∞, not any of the other ones.
 

 If you can do it and I can do it then HHH can
do this same sort of thing. Computations are
not inherently dumber than human minds.
 

 But HHHn isn't given DDD∞ as its input, so that doesn't matter.
 HHHn is given DDDn as its input,
 Remeber, since you said that the input to HHH includes all the memory, if that differs, it is a DIFFERENT input, and needs to be so marked.
 You are just admittig that you are just stupid and think two things that are different are the same.

     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
 

 Right, so the decider needs top be able to show that its exact input will not halt.

 No it cannot possibly mean that or professor Sipser
would not agreed to the second half:
      H can abort its simulation of D and correctly report that D
     specifies a non-halting sequence of configurations.
</MIT Professor Sipser agreed to ONLY these verbatim words 10/13/2022>
 

 Of course it means that, because Professoer Sipser would have presumed that you built the machines PROPERLY, so that you COULD think of changing THIS H to be non-aborting, while the input still used the final version that it always uses,
 

 A machine cannot both abort and fail to abort an input
unless it modifies its own code dynamically.
 Professor Sipser would not have construed that I am referring
to self-modifying code.

That does not really matter. Everything that can be computed with
self-modifying code can be computed without self-modifying code.
