This work proposes a time-symmetric, information-theoretic formulation of quantum mechanics in which both the initial and the final boundary conditions jointly constrain physical evolution. Quantum randomness is treated as incomplete knowledge rather than fundamental indeterminacy. The central element is a measurable coupling parameter, kappa, that quantifies how strongly the two temporal boundaries are aligned and that drives a simple relaxation dynamics toward an informational equilibrium state. We derive kappa from entropy balance and mutual information, prove complete positivity and no-signaling for the resulting dynamics, and give a standard generator form. A delayed-choice quantum random number generator is outlined as an experimental test to estimate kappa with current technology. In the limit of vanishing kappa the usual quantum theory is recovered; nonzero kappa predicts small, testable deviations that link information flow to thermodynamic quantities.
