Do you want me to understand it? If I do, then I deduce that you can prove that neither PAcGC nor PA~cGC. Hence you have proved Gödel's incompleteness theorem and you have proved PA is consistent. So if I understood your definition then you are wrong about Gödel's incompleteness theorem being invalid and you are wrong about PA not being provably consistent.
Perhaps for that reason you don't want me to understand it.
