And in that input there is no question about whether itself halts.
That is in the programming of the analyser.

And the question is not: Do I, the analyser, give the correct answer?
It has no power to declare itself the authority.

What do you even mean? Of course it follows its programming and does not
spontaneously generate an answer. It may not be possible to write such
a program: then there is indeed no machine that can compute it, but the
input still has a defined halting status

There is an obvious mapping from D to its behaviour: run it, or give it
to any simulator /that it does not call/.
