 Being called a "liar" by a liar does not damn.
 As is clear from the above C code, DDD() specifies what HHH specifies
for the case it is called with DDD as the only argument. In particular,
if HHH specifies a recursive for that case then so does DDD. And if
HHH specifies a recursive simulation that can never reach its final
halt state then so does DDD. And if HHH specifies a non-halting
behaviour so does DDD. Etc.

 That is not quite the way that it actually works.

Yes it is. If it were not you would have pointed where there is an
error.

     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
      H can abort its simulation of D and correctly report that D
     specifies a non-halting sequence of configurations.

 DDD emulated by HHH, the directly executed DDD()
and the directly executed HHH() would never stop
running unless HHH aborts its simulation of DDD.

A counterfactual hypothesis is not a valid substitute of the actual
input as the basis of determination.

*According to the above criteria that means*
 When DDD does abort its simulation of DDD then
HHH correctly reports that its input specifies
a non-halting sequence of configurations.

No, it does not, as HHH did not correctly determine that the rest
of the behaviour is non-terminating. If the simulated HHH were
similated further it would abort its simulation and return. The
actual input specifies a partial simulation and later halting.
