Formal systems kind of sort of has some vague idea of what True

Unless expression x has a connection (through a sequence
of true preserving operations) in system F to its semantic
meanings expressed in language L of F then x is simply
untrue in F.

Whenever there is no sequence of truth preserving from
x or ~x to its meaning in L of F then x has no truth-maker

undecidable in F.
Tarski proved that True is undefineable in certain formal systems.
Your definition is not expressible in F, at least not as a definition.

You cannot redefine the foundation of all formal systems. Every formal
system has the foundation it has and that cannot be changed. Formal
systems are eternal and immutable.

Then According to your reasoning ZFC is wrong because
it is not allowed to redefine the foundation of set
theory.
It did not redefine anything. It is just another theory. It is called
a set theory because its terms have many similarities to Cnator's sets.
It <is> the correct set theory. Naive set theory
is tossed out on its ass for being WRONG.
There is no basis to say that ZF is more or less correct than ZFC.
A set containing itself has always been incoherent in its
isomorphism to the concrete instance of a can of soup so
totally containing itself that it has no outside surface.
The above words are my own unique creation.
There is no need for an isomorphism between a set an a can of soup.
There is nothing inherently incoherent in Quine's atom. Some set
theories allow it, some don't. Cantor's theory does not say either
way.

Quine atoms (named after Willard Van Orman Quine) are sets that only contain themselves, that is, sets that satisfy the formula x = {x}.

Wrongo. This is exactly isomorphic to the incoherent notion of a
can of soup so totally containing itself that it has no outside
boundary.
As I already said, that isomorphism is not needed. It is not useful.
It proves incoherence at a deeper level.
No, it does not. If you want to get an incoherence proven you need
to prove it yourself.
>
itself that it has no outside boundary you can see that this is impossible because it is incoherent.
It requires simultaneous mutually exclusive properties.But sets aren't physical things, and thus the "analogy" just breaks.
(a) It must have an outside surface because all physical
things have an outside surface.
(b) It must not have an outside surface otherwise it isNo you don't as a Venn Diagram shows a mapping of "members" to "sets" there is no rule that the set can't also be a member.
not totally containing itself.
When we try to draw the Venn diagram of a set that totally
contains itself we have this exact same problem.
But it doesn't.No one has ever bothered to notice that "undecidability" derivedPrior to my isomorphism we only have Russell's Paradox to show>
that there is a problem with Naive set theory.
Which is sufficicient for that purpose.

What system? They are understood to indicate inconsistency of
the naive set theory and similar theories.

What is "open" in the "issue" of undecidability?

from pathological self-reference is isomorphic to a set containing

pathological self-reference is to reject it as bad input.
Because Quines atom isn't expressed in ZFC."This sentence is not true"The Liar Paradox is isomorphic to a set containing itself:>
Pathological self-reference(Olcott 2004) yet we still
construe the Liar Paradox as legitimate.
Is there someting illegitimate in

rejects it as incoherent. It is like you are trying
to say that a dead rat is alive because Quine says so.
No, Quine isn't using ZFC, so the rules of ZFC just don't apply.It is not allowed to exist.Even ZFC sees that it is incoherent.>
How does ZFC "see" that?

What makes you think Quine did not understand the distinction,
