Excpet, as I have shown, it doesn't.

Your problem is you keep on ILEGALLY changing the input in your argument because you have misdefined what the input is.

You have already said that a decider is not allowed to answer anything
other than its input. Now you say that the the program at 15c3 is not
a part of the input. Therefore a decider is not allowed consider it
even to the extent to decide whether it ever returns. But without that
knowledge it is not possible to determine whether DDD halts.

to non-halting behavior because this finite string calls HHH(DDD)
in recursive simulation.
That mapping is not a part of the finite string and not a part of the
problem specification.
decider/input pairs <are> a key element of the specification.
No, you need to take it FULLY into account, since the program the input represents WILL HALT since the copy of the decider it calls WILL RETUN 0, since that IS the behavior of you claimed to be correct decider.Not of any specification of any interesting problem.Everyone here seems to think that they can stupidly ignore

But since HHH halts, it is a NECCESARY fact that the DDD that just clll that HHH and retuns will halt halt.It is not part of the input in that we already know that>The finite string does not reveal what is the>
effect of calling whatever that address happens to contain.
A simulating termination analyzer proves this.
Irrelevant, as you just said it is not a part of the input.

HHH halts and we only need to find out whether or not DDD halts.
But it can report on the representation of itself it has been given.Not the same. It cannot report on its actual self as a directly>The>
behaviour of HHH is specified outside of the input. Therefore your
"decider" decides about a non-input, which you said is not allowed.
HHH is not allowed to report on the behavior of it actual self
in its own directly executed process. HHH is allowed to report on
the effect of the behavior of the simulation of itself simulating DDD.
Now you said that it is allowed to report on a non-input.
Earlier you have said that it is not allowed to report on a non-input.

executed process. I can report on a copy of itself that it being
emulating in a different process.
