But if x is what you are saying is

 A True(X) predicate can be defined and Tarski never
showed that it cannot.

Sure he did. Using a mathematical system like Godel, we can construct a statement x, which is only true it is the case that True(x) is false, but this interperetation can only be seen in the metalanguage created from the language in the proof, similar to Godel meta that generates the proof testing relationship that shows that G can only be true if it can not be proven as the existance of a number to make it false, becomes a proof that the statement is true and thus creates a contradiction in the system.
That you can't understand that, or get confused by what is in the language, which your True predicate can look at, and in the metalanguage, which it can not, but still you make bold statements that you can not prove, and have been pointed out to be wrong, just shows how stupid you are.

 True(X) only returns TRUE when a a sequence of truth
preserving operations can derive X from the set of basic
facts and returns false otherwise.

Right, but needs to do so even if the path to x is infinite in length.

 This never fails on the entire set of human general
knowledge that can be expressed using language.

But that isn't a logic system, so you are just proving your stupidity.
Note, "The Entire set of Human General Knowledge" does not contain the contents of Meta-systems like Tarski uses, as there are an infinite number of them possible, and thus to even try to express them all requires an infinite number of axioms, and thus your system fails to meet the requirements. Once you don't have the meta-systems, Tarski proof can create a metasystem, that you system doesn't know about, which creates the problem statement.

 It is not fooled by pathological self-reference or
self-contradiction.
 

Of course it is, because it can't detect all forms of such references.
And, even if it does detect it, what answer does True(x) produce when we have designed (via a metalanguage) that the statement x in the language will be true if and only if !True(x), which he showed can be done in ANY system with sufficient power, which your universal system must have.
Sorry, you are just showing how little you understand what you are talking about.
