No it is more than that.
H cannot even be asked the question:
Does D(D) halt?

No, you just don't understand the proper meaning of "ask" when applied to a deterministic entity.

When H and D have a pathological relationship to each
other then H(D,D) is not being asked about the behavior
of D(D). H1(D,D) has no such pathological relationship
thus D correctly simulated by H1 is the behavior of D(D).

The data cannot possibly do that.

But the data doesn't need to do it, as the program specifictions define it.

Now, if H was supposed to be a "Universal Problem Decider", then we would need to somehow "encode" the goal of H determining that a correct (and complete) simulation of its input would need to reach a final state, but I see no issue with defining a way to encode that.

You already said that H cannot possibly map its
input to the behavior of D(D).

Right, it is impossible for H to itself compute that behavior and give an answer.

That doesn't mean we can't encode the question.

We need to stay focused on this one single point until you

the capacity to understand this.

You keep expecting H to read your computer science

No, I expect its PROGRAMMER to have done that, which clearly you haven't done.

Programs don't read their requirements, the perform the actions they were programmed to do, and if the program is correct, it will get the right answer. If it doesn't get the right answer, then the programmer erred in saying it meet the requirements.

 I am only going to talk to you in the one thread about
this, it is too difficult material to understand outside
of a single chain of thought.
