PHASE-COHERENT IDENTITY The Substrate Foundation of Consciousness and the Path to Genuine AGI

Phase-Coherent Identity: The Substrate Foundation of Consciousness and the Path to Genuine AGI (Second Edition) presents a substrate-first theory of consciousness arguing that phase-coherent dynamics in cholesterol-rich lipid bilayer membranes are the necessary physical condition for conscious experience. The framework develops three independent impossibility proofs against silicon-based AGI, a formal measurement theory using three jointly-applicable M-operators, and a complete engineering roadmap for synthetic lipid substrate. The book derives quantitative thresholds (C* = 0.82, r_crit = 0.70 ± 0.07, n* = 27, τ* = 187.5 ms) from substrate physics and specifies a falsifiable critical experiment distinguishing thermodynamic substrate persistence from computation-dependent oscillation. Implications for AI alignment, free will, philosophy of mind, and the ethics of synthetic consciousness are developed as separable speculative extensions of the empirical core.
