Machines as inputs entails that these directly executed

based halt decider.
But they can take the finite-stringt encoding of those machines.

But it isn't a truism, it is just a stupid lie that ignores that almost everything done with programs is via an "encoding" for the input.

When Ĥ is applied to ⟨Ĥ⟩
Ĥ.q0 ⟨Ĥ⟩ ⊢* Ĥ.embedded_H ⟨Ĥ⟩ ⟨Ĥ⟩ ⊢* Ĥ.∞
⟨Ĥ⟩ ⟨Ĥ⟩ simulated by Ĥ.embedded_H reaches
its simulated final halt state of ⟨Ĥ.qn⟩

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.
Then evdrything in reality is outside the domain of Turing Machines.

"the direct execution of the input H^ (H^)" has always been

That no one bothered to notice this ever before
*DOES NOT MAKE ME WRONG*
But it hasn't been, and thus you are just wrong.

An actual rebuttal requires proving that Turing machines
can take directly executing Turing machines (that are not
finite string encodings) as inputs.
But the Turing Machine that is directly executed CAN be represented by a finite string,.

representation has different behavior than the
directly executed machine and halt deciders only
report on the actual behavior actually specified
by their inputs.
