HHH(DDD) correctly determines the halt status of its input according to this specification

what a train wreck.  (But like a train wreck, it's hard to look

Mr. Olcott and Mr. Flibble how you all see their claims.  I wanted to
point out three things:

a) Mr. Olcott claims his HHH simulator detects an non-terminating
input and halts.  But others (I forget who) report that -- due
to a bug -- D would actually terminate on its own.  His HHH
simulator therefore gives the wrong answer.

Not really due to a bug.  D actually /does/ terminate on its own, and that's a consequence of PO's intended design.  (Yes, there are bugs, but D's coding is what PO intended.)

Hmm, I thought some more about this.  What's considered a bug (rather than e.g. a design error) is entirely dependent on the program's specification. 

void DDD()
{
   HHH(DDD);
   return;
}

     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
I did not notice how all of the rebuttals of this have
always committed the straw-man error until yesterday.

A correct simulation has always meant that according
to the rules of the x86 language HHH must emulate
itself emulating DDD.
A correct simulation has NEVER meant that HHH
can interpret "call 000015d2" to mean "jmp 00002183".
Yet all of my reviewers say that HHH must do
something like this so that the behavior of DDD
correctly emulated by HHH matches the directly
executed DDD().
