A correct halt decider is a Turing machine T with one accept state and one reject state such that:

Your "definition" fails to specify "encoding". There is no standard
encoding of Turing machines and tape contents.

By failing to have such a concrete system all kinds
of false assumptions cannot be refuted.

So instead every author makes a false assumption that
is simply believed to be true with no sufficient basis
to show that it isn't true.

Once I prove my point as the x86 level I show how the

Your recent presentations are so far from Linz' proof that they

Show the details of how DDD emulated by HHH
reaches its own machine address 0000217f.
00002172, 00002173, 00002175, 0000217a calls HHH(DDD)
then
00002172, 00002173, 00002175, 0000217a calls HHH(DDD)...
WHAT SHOULD THE NEXT STEPS BE?
As you have been told MANY times, the step after the 0000217a call HHH, should have been the emulation of the instruction at 000015d2, the first instruction of the subroutine HHH that is part of the program DDD.
That you don't understand what a "correct emulation" is, what the semantics of the x86 instructions set is, what a "program" is, or anything related just proves your ignorance and inability to learn basic facts.
Sorry, you are just PROVING that fact, and that you are NOTHING but a pathetic ignorant pathological lying idiot.
