A halt decider is a Turing machine that computes the mapping from
its finite string input to the behavior that this finite string
specifies.

 A halt decider needn't compute the full behaviour, only whether
that behaviour is finite or infinite.

 Hence  HHH(DDD)==0 is correct

 Nice to see that you don't disagree with what said.
Unvortunately I can't agree with what you say.
HHH terminates,
os DDD obviously terminates, too. No valid

 DDD emulated by HHH never reaches it final halt state.

 If that iis true it means that HHH called by DDD does not return and
therefore is not a ceicder.

The directly executed HHH is a decider.

What does simulating it change about that?

 If the simulation is incorrect it may change anything.

 However, a correct simultation faithfully imitates the original
behaviour.

 A correct emulation obeys the x86 machine code even
if this machine code catches the machine on fire.
 It is impossible for an emulation of DDD by HHH to
reach machine address 00002183 AND YOU KNOW IT!!!

 A correct emulation of DDD does reach the machine address 0000217f and
a little later 00002183.

 *That is counter-factual and you cannot possibly show otherwise*

A halt decider is required to predict about the actual execution,
not a couterfactual assumption.
