Structured Resonance in Parturition_ A Systems-Level Model of Labor as Phase Transition

Main paper Abstract Labor is not triggered by a single hormone, organ, or signal cascade—it is the moment when coherence emerges across fetal, placental, maternal, and neural systems. This paper reframes parturition through the lens of CODES (Chirality of Dynamic Emergent Systems), proposing that labor represents a systems-level phase transition governed by structured resonance rather than linear causality. Using the Phase Alignment Score (PAS) as a field-level coherence metric, we model labor onset as the lawful collapse of a multi-system resonance field. This coherence-based framework not only explains previously unpredictable dynamics—such as false labor, preterm activation, and contraction regularity—but offers a new frontier for diagnostics, prediction, and clinical intervention. RIC (Resonance Intelligence Core) provides the computational substrate for real-time coherence detection, making labor intelligible as an emergent, lawful process.
