Note, PROOF belong to a system, and if they try to use something not known to be true in the system, they fail to be a proof, as they don't SHOW the needed result. Note, the "System" can't contain all of the Meta-System, as one important added part of the meta-system, as a set of axioms, was an enumeration of all axioms in the base system. If we try to put that enumeration into the base system, it becomes self-referential and we have an infinite set of axioms, something not allowed in normal formal logic. It is possible to do in a meta-system, as the system has a finite axiomization, so we just need to develope a numbering of that list of axioms. This seems to be part of your problem of not understanding why meta-systems can exist and not be part of the original system, but does describe it,
