Article IV: Planck, Born, and EPR — The Domain of Validity of Quantum Event Realization

This is the fourth paper in a series developing a process–event framework for the physical applicability of quantum theory. Building on earlier papers that introduced a minimal event threshold (Article I), resolved black-body divergences via domain restriction (Article II), and clarified the conditional role of conservation laws (Article III), this work addresses three foundational quantum elements: Planck’s relation, Born’s rule, and EPR correlations. The central claim is operational rather than interpretational: standard quantum postulates can be consistently understood as conditions for the realization of physical events, not as ontological statements about discreteness or nonlocal causation. Quantum theory is treated as a theory of continuous processes whose physical relevance emerges only when a minimal threshold of duration, action, and irreversible registration is crossed. Planck’s constant is interpreted as an empirical scale delimiting event realization, Born’s rule as a process-to-event closure under measurement, and EPR correlations as correlations between local events arising from a single global process. No modification of the quantum formalism or its predictions is proposed.
