One should not that "D simulated by H" is not the same as
"simulation of D by H". The message below seems to be more
about the latter than the former. In any case, it is more
about the properties of H than about the properties of D.

Several people agreed that D simulated by H cannot possibly
reach past its own line 03 no matter what H does.

That fact that as far as we can tell, your "logic" is based on you making up things and trying to form justifications for them, just makes people unwilling to attempt to "accept" your wild ideas to see what might make sense.

Computable functions are the formalized analogue of the intuitive notion
of algorithms, in the sense that a function is computable if there
exists an algorithm that can do the job of the function, i.e. given an
input of the function domain it can return the corresponding output. https://en.wikipedia.org/wiki/Computable_function

Do you believe:

(b) Halting means reaching a final state.
(c) Neither.

In Computation Theory, which is the context of the discussion, Halting means reaching a final state.

The key is that NOT HALTING, means that the machine does NOT reach a final state after an unbounded number of steps of operation.

An aborted simulation does not determine, by itself, if the machine being simulated is halting or not. This seems to be a fact you don't understand.

Halting is strictly a property of the direct execution of the machine, or things that are actually proven to be equivalent, like the (unaborted) simulation by a UTM.

OK that is complete agreement with my correct understanding of the conventional notion of halting.

When we come up with a brand new idea such as a simulating termination

Nope, it means that a correct "non-halting behavior pattern" will be a pattern that when seen in the simulation means that unconditionally the program, when directly run or simulated by an actual UTM, will not halt, per the definition.

As I have said, you really need to stop trying to misuse words, as all it is doing is making you whole concept incompatible with your final goal.

Halting means Halting, so non-haling means non-halting, and that only means that the machine will not stop after an unbounded number of steps.

If you want to have some other meaning, use some other word to make it clear.

 So, you think just repeating your same description provides better definitions for the words?
 By such an unlimited definition, your claim is clearly wrong as the H that D calls could detect it being called by D, and just immediately

Your lack of understanding that D simulated by H cannot possibly reach
past its own line 03 is your error here. We can go through the software
engineering details of exactly why you are wrong.

return 0, while the H called by main just continues simulating through that call and sees the return and the final halting.
 You are just proving how STUPID you are and how you just don't understand how logic and specifications work.
