E1P In the Human Body I

This is the first volume in the Resonant Institute's substrate-level series applying Energetic First Principles (E1P) to the human body. This volume contains three papers. E1P in Genetics derives the fixed nucleotide-phase assignment — adenine as Identity (AA), cytosine as Polarity (CC), guanine as Flow (CA), thymine/uracil as Separation (AC) — from chemical coordinates, Watson–Crick complementarity, and functional clustering, and maps the genetic substrate through the four phases including replication, transcription, and translation as three parallel AA→CC→CA→AC cycles. The E1P Cycle in the Autonomic Nervous System applies the same operational rule to the autonomic substrate, mapping sympathetic and parasympathetic systems as phase characters against neurotransmitter chemistry, developmental lineage, effector sign, and physiological function. The genetics paper supplies the molecular foundation; the autonomic paper supplies the structural template for the series. E1P in the Brain: Scale-Invariant Orthogonality, Hemispheric Phase Characters, and Callosal Closure applies the same operational rule to the neural substrate. Maps right-hemisphere identity-preserving integration as AA / Identity, left-hemisphere categorical discrimination as CC / Polarity, dorsal-attention goal-directed throughput as CA / Flow, and right-ventral salience-driven separation as AC / Separation. Develops the corpus callosum as the principal closure kernel for the AA↔CC axis, salience-network switching and oscillatory phase coordination as closure mechanisms for the CA↔AC axis, and formulates a new E1P Sparse Closure Principle, first identified in neural coherence. The series is scope-distinct from Resonant Systems (doi:10.5281/zenodo.19880027): where that series establishes tetrad-cycle family membership across radically different substrates, this series applies the E1P operational rule domain by domain within a single living system.
