I had to make sure that you understood that halting
does not mean stopping for any reason and only includes
the equivalent of terminating normally.

No.  You're wrong, here.  A turing machine is either running or it's
halted.  There's no third alternative.  If your C programs are not in one
of these two states, they're not equivalent to turing machines.

I doubt that very much.  The whole point of turing machines is to remove
ambiguity and unneeded features from the theory of computation.  A third
alternative state is unneeded.

People may use different words to express the same facts. What some
people call "halting in a non-final state" is called "rejecting" by
some other people. But the facts are what they are independently of
the words used to express them.

THere are lont of gaps in C. Some are mistakes that are corrected in
technical corrigenda. Others are undefined and implementation defined
behaviour. Your program uses non-standard extensions to C so it does
not communicate well. If also is too big to be a part of a publishable
article.

Linz Ĥ is fully defined in terms of H, so its behaviour can be inferred

both Ĥ and H what needs be proven.

Linz says nothing about simulations
 I am the sole inventor of the simulating halt decider.
 Ben Bacarisse contacted professor Sipser to verify that he
really did says this. The details are in this forum about
the same date.
 https://www.amazon.com/Introduction-Theory-Computation-Michael-Sipser/dp/113318779X/
 <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 words 10/13/2022>
And, as I remember, he also verified that he disagrees with your definition of correct simulation.

 *Ben also verified that the criteria have been met*

Right, Ben was willing to do what I am not that you can prove that, by your definition, H can show that it "must" abort its simulation or the input will run forever.
But, just like me, he also agrees that this is NOT the defintion of Halting, so H is just shown to be a correct (partial) POOP decider but ot a Halt Decider, not even for that one input.
So, you are just pointing out the evidence that you are LYING about the ACTUAL Halt Deciders, but just playing word shell games about your POOP.

 
or other methods H may use. Those are already fully determined by the construction. But if H does those (c)..(g)
then so does Ĥ.
