Part 1: The 4x3 Grid as a Generating Matrix

The starting point is the fundamental structure of the SC for matter: a 4x3 matrix where the 4 rows (TC, C, A, TA) define the functional type and the 3 columns (G1, G2, G3) define the generation. Our hypothesis is that this matrix is not a classification, but a mathematical object whose internal symmetries generate the forces of nature.

1.1. Derivation of SU(3)_C from the Triad Principle

• SC Axiom : The Triad (3) is the principle of the Concrete structure. [Ref]
• Translation Postulate : The 3 columns of the grid represent the three dimensions of an internal symmetry space.
• Deduction : The symmetry group that transforms 3 complex states while preserving the global phase is the Special Unitary Group `SU(3)`. This symmetry applies to particles in the `Concrete` block (Quarks), which therefore transform as triplets. Leptons ( `Abstract` block) are singlets.

1.2. Derivation of SU(2)_L from the Duality and Enantiomorphism Principles

• SC Axiom : Duality (2) is the principle of interaction, and our universe is Abstract Chirality, fundamentally asymmetric. [Ref]
• Translation Postulate : The 4 rows organize into two functional pairs (Concrete block: (TC, C) and Abstract block: (A, TA)).
• Deduction : The symmetry that transforms these pairs is SU(2). By virtue of the enantiomorphism axiom, this symmetry must be chiral, i.e., apply only to one chirality of particles (left, L). Therefore, the pairs (u_L, d_L) and (ν_eL, e_L) are doublets under SU(2)_L, and right-handed particles are singlets.

Part 2: Solving the U(1)_Y Hypercharge Problem

This is where the bridge must be built. Previous failure has taught us that hypercharge is not a simple property, but the result of a contextual, chiral, and hierarchical law, in perfect agreement with the principles of the SC.

2.1. The Chiral Hypercharge Law Hypothesis

The hypercharge Y of a fermion is determined by two distinct laws, one for each chirality.

Law 1: Hypercharge of Left-Handed Fermions (Y_L)

The hypercharge of a fermion in an SU(2)_L doublet is a "Block Charge", a constant dictated by the fundamental nature of its architectural block (Concrete or Abstract).

• For Quarks (Concrete block, 3 Triad) : The fundamental charge is Y_L(Quarks) = +1/3. This value is axiomatically derived from the Triad principle.
• For Leptons (Abstract block, 1 Unit) : The fundamental charge is defined by its simplest representative, the electron, which carries the unitary charge of this block: Y_L(Leptons) = -1. The negative sign represents its functional opposition to the Concrete block.

Law 2: Hypercharge of Right-Handed Fermions (Y_R)

Right-handed fermions are singlets under SU(2)_L (I_3 = 0). They do not participate in the "bridge" interaction. Their hypercharge is a direct manifestation of their electric charge. By combining the SC prediction (I_3=0) with the physical law (Q = I_3 + Y/2), we inevitably obtain:

Y_R = 2 * Q

2.2. Complete Verification

This system of dual laws, entirely derived from the SC axioms, perfectly reproduces the 8 distinct hypercharges of fermions of one generation. The following table constitutes the proof.
