    1. Can that be a syntactical system or a formal system just as well and
    still be called a schematic system?

    2. Suppose it's a positive intuitionist system, what are the most
    notable things to consider vis-a-vis extensions?

    My system anchored in proof-theoretic semantics fulfills
    My 28 year goal has been to make
    "true on the basis of meaning expressed in language"
    ALWAYS reliably computable.

    Put you can't do that.

    The problem is that the axiom of induction isn't compatible with proof-theoretics as I understand it.

    That, or you end up with issues that the existance or non-existance of a number that meets a property might not be a truth-bearing statement, and
    you can't tell if it is, until you find the answer.

    This makes "Truth" not a fixed quantity, which isn't very satisfying for
    a logic system. Knowledge might change, but truth shouldn't.

    As you fail to understand it. Look deeper.
    G can be expressed in my system yet is
    rejected as semantically non-well-founded.

    Which means your "system" reject valid math as non-well-founded.

    The bulk of the proof is Godel building in basic mathematics his
    relationship that is the proof-checker.

    Or, you system can't talk about the existance of numbers that satisfy a formula.

    In other words, you are just admitting you system fails to support the
    basics of Natural Number mathematics, and thus is limited.
