What Must Be True Before Anything Can Be True

This document states a minimal structural constraint on persistence and identity without appeal to ontology, modality, or logical axioms. The claim is not explanatory but eliminative: anything that persists must do so without internal contradiction and with sufficient corrective structure to maintain its boundary under disturbance. The statement is intended as a foundational constraint applicable across metaphysics, epistemology, and philosophy of science, independent of theoretical commitments.
