HHH correctly determines through mathematical induction that
DD emulated by HHH (according to the finite string transformations
specified by the x86 language) cannot possibly reach its final
halt state in an infinite number of steps.No, HHH has a bug which makes that it fails to see that there is only a finite recursion,*You are technically incompetent on this point*
When the finite string transformation rules of the
x86 language are applied to the input to HHH(DD)
THIS DD CANNOT POSSIBLY REACH ITS FINAL HALT STATE
not even after an infinite number of emulated steps.
THe fact that HHH doesn't complete this operation, doesn't mean that it isn't what the x86 language says will happen, just that HHH doesn't know that is what happens.
THus, HHH just fails to know what to do, and because you were so stupid as to program it with unsound logic, it gets that wrong answer.
Your problem is you confuse the partial, and thus INCORRECT emulatation done by HHH with the correct and complete emulation specified by the x86 language and the full input which includes the code of HHH from Halt7.c
int DD()
{
int Halt_Status = HHH(DD);
if (Halt_Status)
HERE: goto HERE;
return Halt_Status;
