Freezing by Causal Coherence: Deriving the Phase Transition of Water from Entropic Loop Dynamics

We derive the freezing point of water using the Unified Lattice Model (ULM), a causally-driven entropic framework. Without curve fitting or temperature seeding, we show that freezing emerges as a loop-coherence phase transition in the molecular DAG. This provides a structural reinterpretation of thermodynamics from causal first principles.
