Molecular Chemistry as a Trajectory-Consumptive CGS on the Diamond Graph: Three Parameters, a Blind Protocol, and the Frontier of Topology

Reduction of molecular structure to constrained generative dynamics on a seven-node diamond graph derived from valence classes under Pauli exclusion. Molecules are trajectories; three parameters (residual margin R, cycle compatibility ω, residual recursion rec) classify them. Blind protocol on 30 molecules: 90% isolability accuracy, 100% precision on delocalised systems, ρ(R,reactivity)=0.633. Three errors are systematic and structurally informative. Six chemical categories (aromaticity, anti-aromaticity, ring strain, conductivity, isoelectronicity, isomerism) eliminated as independent concepts. T3/R2 system, fourth verified instance. Answers Open Problem 2 of B2. Fourteenth independent domain.
