Take FIFTY TWO, I think you are stuck in an apparent infinite loop.
You keep on repeating the same basic mistakes.
We define Linz H to base its halt status decision on the behavior of
its pure simulation of N steps of its input. N is either the number of
steps that it takes for its simulated input to reach its final state
or the number of steps required for H to match an infinite behavior
pattern proving that the simulated input would never reach its own
final state. In this case H aborts the simulation of this input and
transitions to H.qn.
Such a pattern NOT existing for the <H^> <H^> pattern, thus your H can't correctly abort and becomes non-answering and thus FAILS to be a decider.
The non-existance has been proven and you have ignored that proof,
showing you have no counter for the proof.
If you want to claim such a pattern exists, you MUST provide it or
accept that your logic is just plain flawed as you are claiming the
existance of something that is impossible.
In effect, you are saying that if you have a halt decider for you halt decider to use, you can write a halt decider.

The following simplifies the syntax for the definition of the Linz
Turing machine Ĥ, it is now a single machine with a single start
state. A copy of Linz H is embedded at Ĥ.qx.
Ĥ.q0 ⟨Ĥ⟩ ⊢* Ĥ.qx ⟨Ĥ⟩ ⟨Ĥ⟩ ⊢* Ĥ.qy ∞
Ĥ.q0 ⟨Ĥ⟩ ⊢* Ĥ.qx ⟨Ĥ⟩ ⟨Ĥ⟩ ⊢* Ĥ.qn
Because it is known that the UTM simulation of a machine is
computationally equivalent to the direct execution of this same
machine H can always form its halt status decision on the basis of
what the behavior of the UTM simulation of its inputs would be.
When Ĥ applied to ⟨Ĥ⟩ has embedded_H simulate ⟨Ĥ⟩ ⟨Ĥ⟩ these steps
would keep repeating:
Ĥ copies its input ⟨Ĥ⟩ to ⟨Ĥ⟩ then embedded_H simulates ⟨Ĥ⟩ ⟨Ĥ⟩...

computation that halts … the Turing machine will halt whenever it
enters a final state. (Linz:1990:234)
This shows that the simulated input to embedded_H ⟨Ĥ⟩ ⟨Ĥ⟩ would never
reach its final state conclusively proving that this simulated input
never halts. This enables embedded_H to abort the simulation of its
input and correctly transition to Ĥ.qn.
No, it doesn't, it shows that the H^ built on an H that doesn't abort
will not halt, but that H doesn't answer. If H does abort, and thus can
give the answer, the logic is incorrect.
FAIL.
if embedded_H does correctly recognize an infinitely repeating
behavior pattern in the behavior of its simulated input: ⟨Ĥ⟩ applied
to ⟨Ĥ⟩ then embedded_H is necessarily correct to abort the simulation >> of its input and transition to Ĥ.qn.
Which it can not do, as shown to be impossible.
Because a halt decider is a decider embedded_H is only accountable for
computing the mapping from ⟨Ĥ⟩ ⟨Ĥ⟩ to Ĥ.qy or Ĥ.qn on the basis of the
behavior specified by these inputs. embedded_H is not accountable for
the behavior of the computation that it is contained within: Ĥ applied
to ⟨Ĥ⟩ because this is not an actual input to embedded_H.
As mentioned before, for the input <H^> <H^> when H^ is based on the H
that claims to correctly go to H.Qn, then UTM(<H^>,<H^>) is shown to
also go to H^.Qn and Halt, so the input that H IS accountable for
doesn't match the behavior that H assigns to it.

THAT is the defined behavior of the actual input to H.
You can define that a cat is a dog, yet the actual simulated input >>>>>> to embedded_H cannot possibly reach its final state NO MATTER WHAT. >>>>>
If the simulated input cannot possibly every reach its final state
no matter what embedded_H does then this simulated input is
correctly determined to meet the Linz definition of never halting.
Except that the simulated input DOES reach its final state if
H/embeded_H goes to H.Qn.
Before embedded_H transitions to Ĥ.qn it has already aborted its
simulated input making it utterly impossible for any aspect of this
simulated input to do anything at all.
Then you are just talking POOP and not halting.
Remember, the definition of Halting is based on what a UTM does with the exact same input, and the UTM WON'T (in fact CAN'T) abort the simulation
at that point but continues on, and that H^ will continue on to use a
copy of H that will do that exact same simulation and abort its
simulation (but not the running of its 'caller'), and transition to H.Qn which means H^ goes to H^.Qn and Halts.
FAIL.
It is just like unplugging your computer, zero more steps are executed.
Except Halting isn't based on what a particular copy does, but what any
copy would do if allowed to run.
FAIL
Seems to me to be just more POOP.
CLEANUP ON AISLE 52, someone has left POOP all over the floor.

Showing that you can do one case does not prove that the same method
works on all, particularly harder methods.
That is just you serving Red Herring.
And that pattern does NOT show up in the simulation by H of H^
Which makes it MORE lies by Red Herring.
FAIL.
Total lack of proof.
Does the proof include the posibility that the input includes a copy
of the decider?
It is always the case that a simulating halt decider can correctly
base its halt status decision on the behavior pure simulation of its
input.
LIE.
Proven incorrect.
If H -> H.Qn then H^ -> H^.Qn and Halts and for H^ <H^> proves H wrong.
We know that this must be true because we know that the pure UTM
simulation of an Turing Machine description is defined to have
equivalent behavior to that of the direct execution of the same machine
Right, but that does't prove what you sy.
You are just LYING out of your POOP.
The problem is that IF the simulating halt decider does abort its
input based on some condition, then it is no longer a source of truth
for the halting status of that input.
It is not answering the question: Does the input stop running?
YOU need to answer, which H are you using?
If H doesn't abort, then H^ is non-halting, but H will never answer.
If H does abort and go to H.Qn, then the pure simulation of the input
WILL halt at H^.Qn, so H was wrong.
FAIL.
It is answering the question:
Would the pure simulation of the input ever stop running?
Right, and if H -> H.Qn it will.
