People tried for more than a year to get away with saying
that DDD was not emulated by HHH correctly until I stipulated
that DDD is emulated by HHH according to the rules of the
x86 language. Then they shut up about this.

 Right, "Correct Simulations" can never be partial.
 Partial Simulations can be partial.
 Deciders can use Partial Simulations, if they do it correctly.
 But to do so, they need to show that the ACTUAL CORRECT SIMULATION of this EXACT input, which needs to represent a PROGRAM, would never halt.
 

*That is not what these words say*
<MIT Professor Sipser agreed to ONLY these verbatim words 10/13/2022>
     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
*its simulated D would never stop running unless aborted*
void DDD()
{
   HHH(DDD);
   return;
}
You already admitted the simulated input to HHH(DDD)
*would never stop running unless aborted*
