Three-Charge Knowledge-System Assembly and SU(3): Symmetry Principles of Artificial Science I (3)

The first two papers of Principles of Artificial Science I developed a gauge-theoretic architecture for Big Knowledge Assembly Dynamics and then implemented its first concrete mechanism through U(1)-based single-charge knowledge assembly. The present paper advances from Abelian transport to non-Abelian internal assembly. Quantum chromodynamics (QCD) supplies the mathematical scaffold: a three-dimensional internal representation, an SU(3) connection, noncommuting generators, path-ordered transport, interaction-dependent curvature, and composite states built from fractionally charged constituents. The purpose is not to identify economic or cognitive systems with subatomic matter, but to convert shared structures previously developed in Integration Science into an operational interface for Artificial Science. Earlier sub-economic dynamics modeled achievement and fear-of-failure as up- and down-type impulses, introduced fractional market charges, represented Freudian Id-Self-Superego structure as a three-color internal space, and assigned consciousness a gluon-like mediating role. The present paper combines these ingredients with a parallel sub-cognitive triplet - truth, belief, and justification - in which language plays the mediating role. A three-index state with indices (a, f, g) separates color-like internal position a, flavor-like type f, and generation-like intensity g. The generation index is linked to Yang’s trichotomy, grounded in earlier mental-logic experiments in which inference-schema weights formed three empirical clusters. We formulate an SU(3) knowledge-assembly interface, weak and strong criteria of assemblability, a Fractional-Charge and Dominance Assembly Principle, and a non-Abelian account of order-sensitive composition, curvature, and holonomy. Proton-like uud states are interpreted as achievement-dominant but risk-aware active states; neutron-like udd states as fear-dominant but still aspirational standing-by states. Their different persistence is connected to the Better-Life Principle of ordinary rationality. The framework concludes by preparing the transition from strong-like internal binding to SU(2)-type externality-driven state transformation in Artificial Science I (4).
