The Arrow of Time as Redistribution Stabilization in the ψ₀–OCM

This priority paper presents a mechanism-level resolution of the arrow of time within the ψ₀–OCM (Osborne Cosmological Model). Irreversibility is shown to arise without modifying microscopic laws, invoking special low-entropy initial conditions, or introducing ad hoc coarse-graining. Instead, temporal asymmetry emerges from a structural transition between unstabilized redistribution and stabilized degrees of freedom, leading to restricted access to redistribution channels. Entropy increase, information loss, and horizon thermality are unified within this framework, while all standard time-reversal-symmetric dynamics are recovered exactly in Redistribution-Locked Zone (RZL) limits. The work provides a unified explanatory origin for macroscopic time asymmetry consistent with established physics.
