their halt status decision. They don't even make a halt status
decision thus cannot make a corrupted one.

 Well, the first two claims are literally untrue - outer HHH effectively uses the static mutable data to pass flags to the inner HHH that modify its behaviour.  The Root flag below is derived from the actual static data and causes inner HHH to totally skip its own abort logic!
 You seem to acknowledge this, but claim it does not matter for various reasons, because whatever mistakes you are making, what finally gets printed out is saying the right thing!
 

 If HHH gets the correct answer in an impure way then it only
counts that it gets it in an impure way if it is impossible
to get in a pure way. This makes it possible for HHH to get
this answer in a pure way:

 Mike Terry is right that a simulator has access to the internal state of the simulated machine, but he did not say that it is correct to *change in this way* the state of the simulated machine.
Changing the state of the simulated machine is cheating.

 I know this and agree with him on this.
 

Of course a simulator can modify the input before of during the simulation.

 No that is cheating too.

 That is exactly what you do when you change the value of the variable 'Root'. 'Root' is a hidden input for HHH.

 If you had sufficient understanding of the x86 language
you would know that DDD is correctly emulated by HHH.

If you had suffient understanding of x86 language and correctness
you would know that DDD is incorrectly emnulated by HHH.
