You really like to make you Herrings Red, don't you.

REMEMBER, the DEFINTION of a Halt Decider is that H applied to wM w is
based on the behavior of M applied to w.

YOU are the one making the wrong report.

Right, so the H that doesn't abort is non-halting and fails to be a decider.

If H does abort its simulation, and transitions to H.Qn, then the H^
that uses that H will also go to H^.Qn and Halt. So, I don't see how a
machine that gets to its final state represents a configuration that
never reaches it final state.

The only machine that your proof mentions that doesn't reach its final
state is H itsself, so that is the only one you have proved to be
non-halting.

Right, and you don't put the care into it to get it right. Your problem
is that as long as the Halting Problem Stands, your formalization is
shown to be flawed.

You can't just 'wish' for the Halting Problem to not be there.

FAIL.
