The Domain of Validity of Quantum Descriptions: A Process–Event Framework (Series Synthesis)

This record presents a review and synthesis of a five-part research series devoted to clarifying the domain of validity of quantum descriptions. The work introduces an explicit process–event framework, distinguishing between continuous quantum processes described by the formalism and their irreversible realization as physical events. Rather than proposing new dynamics or modifying quantum theory, the synthesis operates at a meta-level, making explicit the conditions under which standard quantum concepts—such as Planck’s relation, Born’s rule, conservation laws, entanglement, and Bell-type constraints—acquire physical meaning. A minimal realization criterion, expressed schematically as a resonant event threshold, delineates when a quantum description corresponds to an empirically accessible event rather than a purely formal process. By consistently maintaining the process–event distinction, the framework resolves longstanding conceptual tensions surrounding measurement, nonlocality, conservation laws, and information without altering the mathematical structure or empirical predictions of quantum mechanics.
