I guess you idea of Turing Machine is so limited that you think they can't do arithmatic, as you can't actually put a "Number" as the input, only the finite-string encoding of a number, which puts it outside the domain of them.

Which is just an admission of your lying strawman, as the question is NOT about the (partial) simulation done by your H / embedded_H, but about the direct execution of the input H^ (H^) as that is what the input to H is encoding.

 Because no Turing machine can take a directly executed
Turing machine as an input, directly executed Turing
machines have always been outside of the domain of every
Turing machine based decider.
 "the direct execution of the input H^ (H^)" has always been
out-of-scope for every Turing machine based halt decider.
That no one bothered to notice this ever before
*DOES NOT MAKE ME WRONG*

That is your misconception. No one ever asked to take the direct execution as input. You are fighting windmills again, which is not a rebuttal.
A decider must report on its input.
If exactly this same input is proven to specify a halting program, then the decider must report that it halts.
Whether this proof is by direct execution, by a correct simulation, or by other means, is irrelevant, although the proof by direct execution is of course the easiest to understand.
In this case the input of HHH has been proven to specify a halting program by direct execution. HHH does not need to know that, but when it does a correct analysis it must come to the same conclusion. If not, then HHH is wrong as a self-evident fact.
