Quantum Realization Under Global Temporal Constraints

This preprint is part of a three-paper series exploring physical realization as a temporally organized process constrained by relativistic causality. The present paper addresses quantum outcome realization. Standard quantum mechanics provides a complete and accurate description of state evolution but does not specify how physical outcomes are realized within an already structured world. In this work, a strict separation is made between quantum dynamics and realization. No modification of the Schrödinger equation, operators, or measurement formalism is introduced. A minimal global temporal constraint, T= L / c, is proposed as an organizational condition on realization, arising directly from finite causal connectivity. Quantum states are interpreted as spaces of possible realizations, while actual outcomes emerge through selection constrained by global phase compatibility with previously realized structure. Within this framework, the Born rule appears as the unique statistically stable distribution of realizations required for consistency across composite systems, rather than as a postulate of dynamics. The approach preserves quantum indeterminacy, introduces no hidden variables, and provides a unified account of realization across quantum and macroscopic regimes.
