Then ~True(L,p) can't be a truth beared as they are the SAME STATEMENT, just using different "names".
Truthbearer(L,x) ≡ (True(L,x) ∨ True(L,~x))
p = ~True(L,p) Truthbearer(L,p) is false
q = ~True(L,p) Truthbearer(L,q) is true

Irrelvent.
If Truthbearer(L, p) is FALSE, and since p is just a NAME for the statement ~True(L, p), that means that True(L. p) is not a truth bearer and True has failed to be the required truth predicate.
If you are defining your "=" symbol to be "is defined as" so the left side is now a name for the right side, you statement above just PROVES that your logic system is inconsistant as the same expression (with just different names) has contradicory values.
You are just showing you utter lack of understanding of the fundamentals of Formal Logic.

Why add the indirection? p is the NAME of the statement, which means exactly the same thing as the statement itself.
>
p = ~True(L,p)
does not mean that same thing as True(L, ~True(L,p))
The above ~True(L, p) has another ~True(L,p) embedded in p.

Is the definition of an English word one level LESS of indirection than the word itself?
>
This sentence is not true("This sentence is not true") is true.

Right, that is a sentence about another sentence (that is part of itself)
p defined as ~True(L, p) isn't a sentence refering to ~True(L, p), it is assigning a name to the sentence to allow OTHER sentences to refer to it by name,

I don't think you understand what it means to define something.
>
x := y means x is defined to be another name for y
https://en.wikipedia.org/wiki/List_of_logic_symbols
LP := ~True(L, LP)
specifies ~True(~True(~True(~True(~True(...)))))

Nope.
It means that LP is defined to be the sentence ~True(L, LP)
replacing the LP in the sentence with a copy of LP IS a level of indirection, so you can get the infinite expansion if you keep or derefencing the reference in the statement.

"Definition by example" is worse than "Proof by example", at least proof by example can be correct if the assertion is that there exists, and not for all.

Which isn't a valid proof in a formal system. You seem to think Formal System are a loosy goosy with proofs as Philosophy.

A level of indirection:

p: "This sentence is true", which is exactly the same as "p is true" since "this sentence" IS p
>
p := True(L,p)
specifies True(True(True(True(True(...)))))

Nope, it is equivelent to that, but doesn't SPECIFY that.
As I said above that is expanding levels of indirecction.

*Prolog sees the same infinite recursion and rejects it*
?- TT = true(TT).
TT = true(TT).
?- unify_with_occurs_check(TT, true(TT)).
false.

Right, because prolog can't handle any levels of self referencing, and thus is not suitable for logic that can do that.
You have been told this, but don't seem to understand it. My guess is you can't understand any logic more complicated than what Prolog handles, so don't realize how much it just doesn't handle.
