ψ⁸: Intention as a Fourth-Order Control of Reality

This paper presents ψ⁸ as a foundational framework uniting quantum, biological, and cosmological coherence under a single retentive principle. It defines intention as a fourth-order regulatory mechanism that operates through sustained coherence rather than energetic causality. The ψ⁸ Lagrangian introduces a measurable deformation of the probability metric (ΔS < 0), predicting entropy reduction under stable retention nodes (Ξ). The work bridges physics, information geometry, and ethics, proposing a testable field theory of retentive dynamics — a possible new axis of physical law. Includes full mathematical formulation, Fisher–Lindblad correspondences, dimensional analysis, and experimental outlook. This work belongs to the ψ⁸ Referentive Series on Retentive Field Architecture.
