Note on Methodological Minimalism in Quantum Foundations

This note argues that several long-standing interpretational problems in quantum mechanics persist not because they require additional postulates, entities, or metaphysical commitments, but because their structural core has not been isolated with sufficient clarity. We advocate methodological minimalism: the principle that foundational explanations should introduce no assumptions beyond those already present in the mathematical structure of the theory. We show that key phenomena—most notably measurement and collapse—can be understood as consequences of spectral structure and boundary constraints, without invoking ontological randomness, consciousness, or non-physical mechanisms. Simplicity here is not aesthetic; it is a diagnostic indicator of structural correctness. Diagram https://drive.google.com/file/d/1RLVINPhsgjcNvlLv4W3ee8avLM5wzTya/view?usp=sharing
