It is always correct for any simulating termination
analyzer to stop simulating and reject any input that
would otherwise prevent its own termination.

In this case there is nothing to prevent, because the finite string specifies a program that halts.

This stuff is simply over-your-head.
HHH(DD) meets the above: *Simulating termination analyzer Principle*
Anyone with sufficient competence with the C programming language
will understand this.

Everyone with a little bit of C knowledge understands that if HHH returns with a value 0, then DDD halts.

If HHH would correctly simulate DD (and the functions called by DD) then the simulated HHH would return to DD and DD would halt.

But HHH failed to complete the simulation of the halting program,

HHH is only required to report on the behavior of its

 It is not a good idea to think that everybody is just like you.
 

*Simulating termination analyzer Principle*
It is always correct for any simulating termination
analyzer to stop simulating and reject any input that
would otherwise prevent its own termination.
The only rebuttal to this is to stupidly reject the
notion that all deciders must always halt.
