HH1(DD,DD) does not have a pathological relationship to its input
thus this input terminates normally.
Your terminology is confusing. What you call a "pathological relationship" is that H must simulate itself.

*CONVENTIONAL TERMINOLOGY*
For any program H that might determine whether programs halt, a
"pathological" program D, called with some input, can pass its own
source and its input to H and then specifically do the opposite of what
H predicts D will do. No H can exist that handles this case.

The problem is that your simulator does not even reach the "pathological" part of D.
That is not the problem that is the criterion measure of a solution.
You are using the wrong criterion, because this wrong criterion also also applies to other programs, without a "pathological" part.

So, your criterion has no relation with "pathological" programs.

This criteria works correctly for ALL input, including pathological
main().
You do not even understand you own definition of "pathological":

It seems that you are changing the definition of "pathological" to 'any program for which H returns a false negative', which then becomes a tautology.

understand this.
(Btw, I never refer to my PhD, because I think arguments should convince, not authority.)
