No, it does not. The proof reamins as it was. A proof is valid if there

There are errors that you do not understand.
For the purpose of these discussion it is not neessary to understand
your errors beyond that they are errors.
int DD()
{
int Halt_Status = HHH(DD);
if (Halt_Status)
HERE: goto HERE;
return Halt_Status;
}
*There are errors with the proof*
(1) Simulating terminator HHH makes the second line
of code unreachable for DDD simulated by HHH according
to the semantics of the C programming language.
*No one ever noticed that before my work*
(2) This makes the conventional halting problem proof
counter-example input decidable when decided on the
basis of the actual behavior that its input actually
specifies.
(3) Halt deciders only report on the behavior that their
input actually specifies even though some textbooks
disagree.
This group is not for those
who want to understand errors but for those how want to understand
more about the theory of computations. All readers need to know about
you is that what you say is not the understanding they seek.
