A Modular Coherence Measurement and Drift-Detection Framework (Ψ-Formalism)

This repository contains a modular instrument package documenting the design, mathematical specification, safety constraints, and evaluation methodology of a coherence-based measurement and drift-detection framework derived from the Copeland Resonant Harmonic Formalism (Ψ-formalism).The materials are intentionally non-linear and self-contained. Rather than presenting a single narrative paper, the package is organized as a set of interoperable reference documents addressing distinct concerns:formal definition of the coherence metric Φdeterministic, bounded reference implementationsnapshot- and range-based evaluation frameworksexplicit non-diagnostic and non-therapeutic safety posturestructural mapping between human-facing measurement and AI drift-detection (RCDD) systemsconceptual modeling of symbolic-layer coherence failure and recoveryEach file may be read independently. Apparent redundancy across documents is deliberate and serves auditability, safety, and misuse resistance.This repository is intended for researchers, engineers, and governance bodies interested in measurement-first approaches to coherence, stability, and drift across human, artificial, and hybrid systems. It does not propose new physical constants, psychological claims, or behavioral prescriptions.The collection should be understood as an instrument ecosystem, not a single theoretical argument.
