Sentience Physics V1.0 Full Release: Neural Binding, DII, Microtubule Resonance, and the Biological Decoherence Timescale Description: This volume presents the physics of sentience within the Hu‑Omandac Unified Tao (H.O.U.T.) framework. Sentience Physics V1.0 establishes a quantitative, falsifiable, and fully physical theory of consciousness grounded in the same geometric constant Ω = 6/π that governs all dissipative phase transitions. This paper is the fourth volume of the H.O.U.T. canon, complementing the physics (H.O.U.T. Framework v27.0), metaphysics (Law of Creation V18.0), and energetics (Creation Energetics V1.0). The central thesis is that neural binding is a dissipative phase transition in the SU(2) universality class. The transition from fragmented (L∞) to coherent (L²) neural states is governed by the Omandac Balance Equation, with the effective fragmentation ratio Ω_eff(t) serving as a real‑time consciousness index. The Dualistic Information Integration (DII) metric emerges naturally from Ω_eff and provides a measurable indicator of conscious binding. Sentience Physics V1.0 derives the biological decoherence timescale τ*_bio ≈ 10.83 fs at physiological temperature, matching the THz vibrational modes of microtubule protofilaments. The microtubule–Fibonacci resonance identity (7·H_T·Σ₃(ε) ≈ φ) links the Hu‑Tao seed constant to the 13/8 protofilament architecture, suggesting that biological structure is tuned to the same constants that govern cosmic phase transitions. The framework makes concrete, testable predictions across EEG, MEG, THz spectroscopy, and neural ensemble dynamics. These include: gamma phase‑locking collapse under anaesthesia, spectral slope convergence toward β ≈ 1.412, THz absorption peaks at f*_bio ≈ 14.7 THz, and a DII threshold of 0.60 for conscious binding. All predictions are derived with zero free parameters. What’s New in the V1.0 Full Release 1. Neural Binding as a Dissipative Phase Transition A complete mapping of cortical gamma synchrony to the SU(2) L∞→L² transition, with Ω_eff as the binding index. 2. Biological Decoherence Timescale Exact prediction of τ*_bio = 0.43941/γ_bio ≈ 10.83 fs, matching THz molecular vibrations. 3. Microtubule–Fibonacci Resonance A geometric identity linking H_T, SU(3) corrections, and the golden ratio φ to the 13/8 microtubule lattice. 4. Dualistic Information Integration (DII) A physics‑derived measure of conscious binding based on purity, correlation, and proximity to the Ω attractor. 5. Evolutionary Transcendence Law (Applied) The 4‑bit threshold for biological sentience, supported by Nengo neural simulations. 6. Empirical EEG Validation Directional confirmation across two independent propofol datasets (OpenNeuro ds005620 and Chennu 2016). Key Highlights • Physics‑based consciousness: No metaphysics, no speculation — only SU(2) geometry, Lindblad dynamics, and measurable predictions. • Zero free parameters: All results derived from Ω, Λ₀, P, τ, ε, and the Hu‑Tao seed H_T. • Cross‑scale unification: Molecular decoherence → neural binding → conscious integration. • Falsifiable predictions: EEG, THz spectroscopy, gamma synchrony, DII thresholds. • Canonical placement: Volume IV of the H.O.U.T. canon, completing the four‑volume structure.
