This not Linz's Ĥ.  Linz's H leads to a contradiction because of how H
and the "hat" construction are defined.  Using a different "hat"
construction, and an "adapted" halt criterion, means you are not
addressing Linz's (or anyone's) proof.  Why do you think anyone will
take any claims about your bogus seriously?

A halt decider would have this simple behaviour:

  J ⟨M⟩ s ⊢* J.qy  if M applied to s halts, and
  J ⟨M⟩ s ⊢* J.qn  if M applied to s does not halt.

(I've changed the name because you are abusing H and Ĥ to refer to TMs
that do not meet Linz's specifications.)

Which, with the correct "hat" construction applied, results in

  Ĵ.q0 ⟨Ĵ⟩ ⊢* J ⟨Ĵ⟩ ⟨Ĵ⟩ ⊢* J.qy ⊢* oo   if J applied to ⟨Ĵ⟩ ⟨Ĵ⟩ halts, and
  Ĵ.q0 ⟨Ĵ⟩ ⊢* J ⟨Ĵ⟩ ⟨Ĵ⟩ ⊢* J.qn       if J applied to ⟨Ĵ⟩ ⟨Ĵ⟩ does not halt

which, as Linz says, is clearly nonsense.  No TM can behave as Ĵ was
assumed to behave.

I bring this up only for the benefit of anyone who is still interested
in how the proof works.  You stopped talking about the halting problem
and it's proofs some while ago, having failed to persuade anyone that
the wrong answer is the right one.

Bit of a nerve to cite Linz when you are ignoring his specification and
his proof!
