Unified SGCI–PCI/SISSI Framework: A Formal Coherence-Based Information Model This work presents a unified theoretical and computational framework combining the SGCI (Spectral Generalized Coherence Index), the PCI/SISSI coherence-field model, and a falsification-oriented numerical protocol. The goal is to establish a rigorous and testable foundation for a physics of coherent information, based on oscillatory dynamics, phase synchronization, and isotopic sensitivity (H₂O/D₂O). The manuscript integrates: the SGCI method for quantifying harmonic-weighted spectral similarity, the PCI/SISSI field-theoretic representation of coherent information, a numerical protocol designed to detect, validate, and falsify coherence under perturbations, an experimental proposal leveraging isotopic water differences as an empirical test case. The unified framework bridges spectral, dynamical, and field-level descriptions, providing a structured approach for exploring coherence phenomena in physical and biological systems. While simplified, the model generates clear, falsifiable predictions and offers a conceptual basis for future experimental and theoretical development. This record expands and formalizes the ideas presented in the original SISSI demonstration, providing a manuscript-ready version suitable for citation, peer review, and further research.
