When D is correctly simulated by H using an x86 emulator the only
way that the emulated D can reach its own emulated final state
at line 06 and halt is
(a) The x86 machine code of D is emulated incorrectly
(b) The x86 machine code of D is emulated in the wrong order

Which isn't a "Correct Simulation" by the definition that allow the relating of a "Simulation" to the behavior of an input.

Right the execution trace of D simulated by pure function H using
an x86 emulator must show that D cannot possibly reach its own
simulated final state and halt or the simulation of the machine
language of D is incorrect or in the wrong order.

So, you aren't going to resolve the question but just keep up with your contradiction that H is simulating a template (that doesn't HAVE any instrucitons of H in it) but also DOES simulate those non-existance instructions by LYING about what it does and simulating a SPECIFIC instance that it LIES behaves just like DIFFERENT specific instatces.

The infinite set of every H/D pair specified by the template

 If we assume that a decider takes an actual Turing machine as its
input that is correct otherwise that is one level of indirection
away from what we are really looking at.
 The people have perpetuated this mistake for many decades never
actually made it not a mistake.
 

You need to define what you mean by "Indirection", because you aren't using it in the normal manner.
A complete representation of the Turing Machine is NOT a level of Indirection.
Using a "Name" to represent that full description, THAT would be indirection.
The x86 code for your functions isn't a level of indirection from the function itself.
A word with the address of the function would be.
