FRC 566.001: Entropy–Coherence Reciprocity and UCC

Introduces the entropy–coherence reciprocity (a compact relation between disorder and order) and the Universal Coherence Condition (a continuity equation for coherence). Explains how this connects to thermodynamics, proves a simple dissipation property, and provides three small, reproducible examples (chemical toy, stochastic field, and a coherence‑regularized classifier).
