The trace does not show that HHH returns so there is no basis to
think that HHH is a decider.

The trace shows the data of the executed program of HHH that does
halt.

It shows some of the data, not all, and in particular, not the
halting.

DDD emulated by HHH according to the semantic meaning of its x86
instructions never stop running unless aborted.

Bla bla.

You have shown that you do not understand the semantics of the x86
language.
HHH does abort and halt after N cycles,

That is counter-factual

Then HHH is not a decider.
 

When we examine the infinite set of every HHH/DDD pair such that:
HHH1  One step of DDD is correctly emulated by HHH HHH2  Two steps of
DDD are correctly emulated by HHH HHH3  Three steps of DDD are correctly
emulated by HHH ...
HHH∞  The emulation of DDD by HHH never stops

DDD only calls HHH, which, being a decider, halts.

You didn't bother to pay close enough attention.
I referred to every pure function HHH that can possibly exist.
In each case DDD never makes it past it fourth instruction.
This means that every HHH that halts is correct to reject its
DDD as non-halting. Not every HHH halts.
