ΔΦ LAW OF BIOLOGICAL COHERENCE MAINTENANCE (V2.0) A Conserved Continuity Process Governing Multicellular Coordination

Multicellular organisms maintain coordinated function across neural, immune, vascular, and metabolic systems despite constant perturbation, noise, and the absence of centralized control. Contemporary biological theory describes this coordination using outcome-based terms such as homeostasis, regulation, synchronization, and immune tone, yet lacks a conserved process that explains how coordination itself is maintained or why it fails globally before structural damage occurs.This paper introduces Biological Coherence Maintenance (BCM) as a first-order biological process governed by the continuity of a tension current defined as ΔΦ = ρ × v, where ρ represents biological field density and v represents transport or phase velocity across gradients. BCM is formulated as a conserved, non-equilibrium coordination mechanism that preserves phase alignment across distributed biological subsystems. A ΔΦ-based continuity equation, constrained action principle, entropy formulation, and curvature-driven failure mode are presented.The framework is explicitly mechanistic and non-teleological, introducing no new forces, treatments, or disease claims. BCM operates upstream of biochemical dysfunction and structural injury, providing a formal explanation for why systemic coordination loss precedes pathology across diverse biological contexts. By embedding biological coordination within a continuity-driven architecture already established across physical systems, this work fills a foundational gap in biological theory and offers a unifying process model for multicellular coherence.
