Mechanism Architecture, Novelty, and Model Comparison in the ψ₀–OCM A Framework-Level Audit, Shared Limits, and Discriminating Predictions

This paper presents a framework-level audit of the ψ₀–OCM (Osborne Cosmological Model), focusing on its mechanism architecture, points of novelty, and formal relationship to existing physical theories. Rather than proposing new phenomenology in isolation, the work systematically examines how ψ₀–OCM functions as a closed, internally consistent dynamical system and how classical frameworks arise as shared stabilization limits within it. The paper is structured around three core objectives. First, it provides a mechanism architecture audit, identifying the minimal generative components of ψ₀–OCM—redistribution flux, holographic boundaries, detachment states (PDS-0, PDS-1, PDS_T), and stabilization regimes—and showing how these mechanisms jointly govern cosmological, gravitational, quantum, and biological behavior. Second, it establishes shared-limit reductions, demonstrating explicitly how General Relativity, Quantum Field Theory, and ΛCDM emerge as effective descriptions within redistribution-locked and stabilization-dominated regimes, without requiring modification to their empirical content. Third, it formulates a set of discriminating predictions that separate ψ₀–OCM from standard models in active redistribution zones, non-equilibrium cosmology, horizon dynamics, dark sector behavior, and detachment-driven phenomena. Unlike comparative surveys that rely on parameter fitting or phenomenological overlays, this work emphasizes mechanism count, closure, and explanatory scope as evaluative criteria. It shows that ψ₀–OCM introduces no ad hoc degrees of freedom, resolves known conceptual gaps between classical and quantum descriptions, and provides a unified dynamical origin for energy, spacetime curvature, matter stabilization, and emergent complexity. The result is a falsifiable, reduction-complete framework that complements existing theories while extending their domain of applicability.
