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

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

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.
