Exactly. Didn't you say it is allowed to abort?

Bullshit. It can take other machines just fine. It doesn't know about
itself.

Can you prove that a Turing machine is not a finite string?

Your own attempts of a conter-proof are not about Turing machines
but C programs. C programs are finite strings, so a C program
is a valid input to a C program (and a Turing machine, too).

I can't to the same thing for embedded_H and ⟨Ĥ⟩ ⟨Ĥ⟩ so we have to learn
by analogy.

This means that H is not allowed to report on the behavior of the
directly executed P(P).

So on which program does it report then?

Indeed, *only if*. if HH does not halt, then DD does not halt. But your claim is that HH halts, because of that DD(DD) *DOES* halt. You cannot base a conclusion on something that does not happen.

 No, your are twisting your own words.
 

*Verified facts* (some may be beyond your technical competence)

 Up to now, your have not been able to tell how they were verified. It seems beyond your competence to see the difference between verified facts and wishes. That is twisting the meaning of words.
 

(1) The input to HH DOES NOT HALT.

 Only if HH (as part of the input) does not halt.
You even proved that this conclusion is a false negative on 05.jun.2024 at 15:59 (CET)
 

>
(2) HH correctly recognizes that its input DOES NOT HALT.

 Only if HH would not abort, but it does abort.

<MIT Professor Sipser agreed to ONLY these verbatim words 10/13/2022>
   If simulating halt decider H correctly simulates its input D
   until H correctly determines that its simulated D would never
   stop running unless aborted then
   H can abort its simulation of D and correctly report that D
   specifies a non-halting sequence of configurations.
</MIT Professor Sipser agreed to ONLY these verbatim words10/13/2022>
I stop at the first big mistake so that we can focus on correcting
this big mistake.
When
   simulated D would never stop running unless aborted then
   H can abort its simulation of D and correctly report that D
   specifies a non-halting sequence of configurations.
