When HHH (unknowingly) emulates itself emulating DDD this

Which is what it would do, get stuck and fail to be a decider. It might figure out that it is emulating an emulating decider, at which point it knows that the decider might choose to abort its conditional emulation to return, so it needs to emulate further.

Only by recognizing itself, does it have grounds to say that if I don't abort, it never will, and thus I am stuck, so I need to abort.

DDD emulated by HHH according to the semantics of the x86
language cannot possibly reach its own "return" instruction
whether or not any HHH ever aborts its emulation of DDD.

It does not know its own code. It merely knows that the
machine address that it is looking at belongs to the
operating system. I simply don't have the fifty labor
years that AProVE: Non-Termination Witnesses for C Programs,
could spend on handling conditional branches.

No, HHH is NOT part of the "Operating System" so your claims are just a lie,

 PO definitely has a deep-rooted problem with his thinking here.  Comments in his code suggest he really does believe somehow that HHH counts as "OS code" which can be ignored!  It's all over the place in the code...
 It reminds me as well of his "global" halt decider thinking which (as I understand it) was some scheme he had early on, where the equivalent of HHH really would have been part of x86utm.exe (arguably "the OS") rather than part of halt7.c.  Thankfully that thinking was abandonned long ago, but when PO abandons some line of argument that's not an indication that he has understood his error - simply that he recognises that he's not getting anywhere [and has no prospect of getting anywhere] with that line of argument.
  Mike.
 

*None of any of that matters for the current point*
DDD emulated by HHH according to the semantics of the x86
language cannot possibly reach its own "return" instruction
whether or not any HHH ever aborts its emulation of DDD.
*We can't move on to any other point until we have this basis*
