Yes, your observation is correct and important:
The standard diagonal proof of the Halting Problem makes an incorrect
assumption—that a Turing machine can or must evaluate the behavior of
other concurrently executing machines (including itself).

 Functions computed by Turing Machines are required to
compute the mapping from their finite string inputs and
are not allowed to take directly executing Turing machines
as inputs. *No Turing machine can ever do this*
 

WRONG.
"Functions" are the mathematical concepts which *CAN* take Turing Machines, and thus their behavior when executed as an input.
When distilled to a question to ask a Turing Machine (or other computation method), such abstract concepts need to be represented as a finit string.
The Turing Machine is only CAPABLE of doing

This means that every directly executed Turing machine is
outside of the domain of every function computed by any
Turing machine.

Nope,  unless you also consider addition outside the domain of a Turing Machine, as you can't put "a number" on a tape, only a representation for one.
Sorry,

 Thus the behavior of the directly executed DD() does not
contradict the fact that DD correctly simulated by HHH
cannot possibly reach its own “return” statement final
halt state.

Your problem is you presume something that doesn't happen.
Your HHH doesn't "correctly simulate" its input, and thus you criteria is just a LIE.

  int DD()
{
   int Halt_Status = HHH(DD);
   if (Halt_Status)
     HERE: goto HERE;
   return Halt_Status;
}
 This enables HHH(DD) to correctly report that DD correctly
simulated by HHH cannot possibly reach its "return" instruction
final halt state and not be contradicted by the behavior of the
directly executed DD().
 

Nope, it just proves that you are just a liar and don't understand the nature of reality.
Since DD needs to include the HHH that it calls to be simulated at all, (again something you don't seem to understand) that means that since you HHH is admitted to report an answer of non-halting, that it will also return that answer to DD and thus DD will halt.
And an actual correct simulation of the DD that includes that HHH will show this.
Thus we have the following list of lies that you arguement is based on:
1) If HHH(DD) is not asking HHH about the behavior of the direct execution of DD, then your DD is not the equivalent of the proof program, as that is what it was defined to do, to ask the decider about the behaivor of its own direct execution.
2) You claim that the "input" is just the code of DD, and not the HHH that it calls, but then DD isn't actually a "program" (or more precisely, an algorithm) as by definition, those contain all the code / algorithmic steps they use. Again, you have lied that your input is what you claim.
3) Also, if the "input" doesn't include the code for HHH, then how can a "correct simulation of the input" see any of HHH to simulate it, as it isn't part of the input. Thus, your claim that HHH correctly simulates "its input" is just a lie, by omitting that it also uses other information.
4) Since the behavior of the actual input "DD" depend on the HHH that it has been paired with, that means that each version of that input that has been paired with a different decider is different, and thus when you talk about your "Hypothetical decider" (which doesn't abort, and thus does a correct simulation of its input, assuming the input includes the decider it is built on) is looking at a DIFFERENT input, and thus the fact that you can prove that the "Hypothetical Input" built on the "Hypothetical Decider" will not halt, says nothing about THIS input, so your claim it does is just another of your many lies.
5) Since "Halting" is a property of THE MACHINE, and thus the direct exectuion of the Program / Algorithm that is the topic of the discussion, you attempts to us "Non-Halting" to refer to the fact that a PARTIAL simulation didn't reach the end, is just a LIE. "Programs" don't just stop in the middle, they either DO reach a final state, or they run for an unbounded number of steps. Showing they don't stop in some bounded number of steps is NOT showing non-halting, and just a LIE.
6) You claim induction proof is a lie, as each input simulated for each finite length is a different input (since it must contain the code of the decider it is built on, and thus since the decider is changed to simulate different amounts, and you changed the input to use that new decider, and thus is different from all the others), and thus you haven't proven a fact of *A* input simulated for all values of N, but for N different input simulated each for just one value of N.
Since these errors have been pointed out to you many times, and you keep on trying to change your definitions to try to define aways which ever one was last pointed out (and thus making it clear that one of the other ones if fully a problem), all you have done is proves that you are nothing but a liar.
