While this is an advanced topic, no non-trivial systems are closed without appeal to reality. (Realism, materialism, operationalism, empiricism, internally consistent, testifiable).This is why a proof is only a test of internal consistency and a truth requires coherence(reality).

@DSchrooner Closure (logic): a system(paradigm) wherein a proposition is decidable without appeal to information external to the proposition. i.e. Physical closure, logical closure (internal), closure by analogy(knowledge), closure by intuition(experience), closure by truth vs preference.
