Dimensional Analysis and Dimensional Closure of the Shteim Field Equation

This document presents the formal mathematical framework and dimensional verification of the Shteim Unified Field Equation, coupling spacetime curvature directly with electromagnetic potential. Through rigorous dimensional reduction, the model demonstrates exact dimensional closure at [L^{-2}], confirming the total cancellation of mass [M] and time [T] units via the Dynamic Braking Operator (F = c^4/G).
