Follow the details of the proof of Gödel's Incompleteness
Theorem, and apply them to your "system".  That will give you
your counter example.

 

My system does not do "provable" instead it does "provably true".

 

I don't know anything about your "system" and I don't care.  If
it's a formal system with anything above minimal capabilities,
Gödel's Theorem applies to it, and the "system" will be incomplete
(in Gödel's sense).

 

I reformulate the entire notion of "formal system"
so that undecidability ceases to be possible.

 

Liar.  That is impossible.

When you start with truth and only apply truth preserving
operations then you necessarily end up with truth.
Is that too difficult for you?

 

Not at all.  One of the truths you inescapably end up with is Gödel's
Theorem.  Either that, or the system is self-contradictory or too weak
to do anything at all.

 

Gödel's theorem cannot possibly be recreated when
True(x) is defined to apply truth preserving
operations to basic facts.

 On the contrary, whether or not True(x) can be so defined, Gödel's
theorem cannot be avoided.

That would appear to be well beyond your level of understanding.  You
ought to show some respect towards those who do understand these things.

 

I have spent 22 years focusing on pathological self-reference.
My understanding really is deeper.

 It might be a little deeper than it was, but that's not saying very much.
The concept of proof by contradiction, for example, is way beyond you.
Even the very idea of a mathematical proof, its status, its significance
is beyond you.  You don't even understand what it is you're lacking.
 Those 22 years have been suboptimally spent.
 As I said, you ought to show a bit of respect to those who understand
these mathematical things.
 

So you don't understand that when True(x) is
defined to only apply truth preserving operations
to basic facts that are stipulated to be true
that every input including random gibberish
and self-contradiction IS DECIDABLE AS TRUE OR ~TRUE.
