We stipulate that the only measure of a correct emulation is the

You should use the indices here, too, e.g., "where 1 to infinity steps of
DDD₁ are correctly emulated by HHH₃" or whatever you mean.

 If the function called by DDD is not part of the input then the input does
not specify a behaviour and the question whether DDD halts is ill-posed.
 

We don't care about whether HHH halts. We know that
HHH halts or fails to meet its design spec.
We are only seeing if DDD correctly emulated by HHH
can can possibly reach its own final state.
