But what does aborting the simulation have to do with returning the
answer to the caller. THEY ARE DIFFERENT.

You don't seem to be able to understand the fundamental Software
Engineering concept of execution context.

After H aborts the simulation, it needs to do something. By its
requriements, it needs to return that answer to its caller.

When it does, it tells that caller that it thinks that P(P) is
non-Halting, but when it does that to the caller P, that P then halts,
showing that the answer it gave was wrong.

The FUNDAMENTAL definition of Halting is what the machine does when run
as a machine with the given input. It is shown that P(P) does Halt (and
you admit this at times) thus P(P) IS a HALTING computation, by definition.

The non-Halting answer is wrong, by definition.

Any 'logic' that 'proves' otherwise is by definition wrong or at least
shows the logic is inconsistent.
