Not necessarily. Just because everyone falsely assumes that D correctly
simulated by H must have the same behavior as the directly executed D(D)
does not make this false assumption true.

You still need to explain how you can call a simulation that differs from
the behaviour of its input "correct".

Nonsense!  How about, instead of "proving", actually explaining?  If a
simulation differs from its original, it's not a simulation; it's just a
random program.

 typedef void (*ptr)(); // pointer to void function

 Unless I make every single detail 100% explicit false
assumptions always slip though the cracks. The ONLY way
to make EVERY SINGLE DETAIL 100% EXPLICIT is the x86
programming language.
 There cannot possibly be any H that correctly emulates
the x86 machine code of D according to the semantics
of the x86 programming language such that the emulated
D ever reaches its own emulated final state at machine
address [00001f58].
 

Which is just a strawman, as the requirement on H is NOT to answer about "D correctly simulated by H" but about "the program represented by the input directly executed", or equivalently, simulated by an actual UTM, which is a simulator that NEVER stops until it reaches a final state.
For this input, D(D), since H(D,D) returns 0, D(D) will Halt, so H is just wrong by definition, and you by the attempt to use a strawman.

 Once the above is understood (people quit denying verified facts).
thenn (then and only then) I can show how this applies to Turing
machines.
 

No, YOU are the one denying DEFINED FACTS.
