What makes it different fron Goldbach's conjecture?
I think a better example might be Goodstein's theorem [1].

The only drawback is that the theorem is somewhat more complicated
than Goldbach's conjecture -- not a lot, but a bit.

I am establishing a new meaning for

Formerly known as {analytic truth}.
This makes True(L,x) computable and definable.
You may say that, but you then refuse to do the work to actually do that.

When we understand that True(L,x) means that there is a finite

meaning of x to x in L, then mathematical incompleteness is abolished.
Except you just defined that this isn't true, as you admit that the Goldbach conjecgture COULD be an analytic truth even if it doesn't have a finte sequence of truth perserving operations,
I redefined analytic truth to account for that. Things
like the Goldbach conjecture are in the different class
of currently unknowable.
In other words, NOTHING you are talking about apply to the logic that anyone else is using.

Note, Godel's G can't be put into that category, as it is KNOWN to be true in PA, because of a proof in MM
You ONLY construe it to be true in PA because that is
the answer that you memorized.
No, it is True in PA, because it is LITERALLY True by the words it uses.

When you understand that true requires a sequence of
truth preserving operations and they do not exist in
PA then it is not true in PA.
But they DO exist in PA, I guess you just don't understand how math works.

keep repeating counting up through all the Natural Numbers.
From the trick in MM, we can see that the math in PA will say no to all of them.

Thus, after an infinite number of steps of truth preserving operations, we reach the conclusion that NO natural numbers actually exist that meet that PRR, just like G claimed, so it is correct.

The lack of a proof means untruth.
Nope, lack of a proof means unknown, as you have agreed.
provable in PA then G is untrue in PA.
Right, Just like they showed that G is true.After all, you admitted that if the Goldbach conjecture would be an Analytic TRUTH if it was only established by an infinite sequence of truth preserving operations.If an infinite number of steps do show that Goldbach is

provable in PA then Goldbach is true in PA.
No, "Proofs" can not have an infinite number of steps, proofs are ALWAYS finite in conventional logic.Since you don't know the meaning of the words, you just prove yourself unqualified to talk about such things.Any proof requiring an infinite number of steps never resolved

An alternative finite proof in MM only shows that the expressionNope, since the rules of math are the same, it must also be true in PA.
is true in MM.
Truthmakers cannot cross system boundaries. --But the base truthmakers for G in MM and PA are the same items, there is just a short cut in MM to let us colapse the infinte chain to a finite chain.
