Gauge Theory as the Language of Substrate Symmetry.
Deriving $U(1) \times SU(2) \times SU(3)$.
$A_\mu$ as Substrate Connection.
$F_{\mu\nu}$ as Substrate Curvature.
Reconstructing $\mathcal{L}_{gauge}$.
Determining $g_i$ from $K$ and $P$.
Symmetry Mapping Closure.
The Standard Model is reconstructed as the geometric limit of substrate dynamics. Symmetry is not an input; it is a structural consequence of the $(N, C, M)$ triadic fields.
FINAL STAGE STATEMENT
The Standard Model is not a fundamental theory of particles and forces, but an exact gauge-theoretic representation of substrate dynamics governed by the structural parameters K and P.
