     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.

The fact is that it *WOULD* in fact keep repeating,
thus *IT DOES* get the correct answer.

The fact is that all deciders only report on the behavior
specified by their inputs and non-inputs are non-of-their-damn
business.

When HHH computes the mapping from its finite string input
of the x86 machine code of DDD to the the behavior that DDD
specifies HHH correctly predicts that DDD cannot possibly
stop running unless aborted.

The reason that this seem so strange is not that I am incorrect.
The reason is that everyone rejected simulation as a basis for a
halt decider out-of-hand without review. Because of this they
never saw the details of this behavior when a termination analyzer
correctly emulates an input that calls itself.

They never notices that there could possibly be a case where
the behavior of the emulation of the machine specified by its
own Machine description (x86 language) could differ from
the direct execution of this same machine.

> But HHH cannot possibly simulate itself correctly.

The ONLY measure of simulated correctly is that each x86
instruction of N instructions of DDD is emulated correctly and
in the correct order. 2 + 3 = 5 even if you don't believe in numbers.
