McCaul's Law of Coherence: A Narrative Reconstruction of Discovery — The Chronological Development of MCP* from Geometric Intuition to Universal Physical Law

This paper documents the complete intellectual development of McCaul's Law of Coherence, tracing the progression from an initial geometric observation about the Seed of Life (SOL) structure to the formal derivation and blind cross-domain validation of the McCaul Coherence Potential (MCP*) as a universal physical invariant. Beginning with the computational modeling of a novel 3D rotational SOL lattice (541 nodes, 14,580 edges, spectral radius 66.0), the research advanced through the instinctive design of a plasma-optic measurement instrument, the identification of a cross-domain coherence pattern, and the formal definition of MCP* = (P_r x B_r x N_r x F_g x C_r x H_r)^(1/6). Blind pre-registered validation across seven independent datasets in six physical domains confirmed the law with Cohen's d values from 1.61 to 319.26 and AUROC scores from 0.800 to 1.000. Theoretical extensions include: the C = SOL Theorem, the quantum 7th State threshold (N_r >= 0.7937), and the zinc spark at fertilization as biological 7th State crossing.
