Based on the global theory of helical dimensions, this study completes the theoretical derivation and error correction of the fine-structure constant relying on the universal original laws including progressive dimension attenuation, multi-layer nesting, and axial precession of helical dimensions, combined with endogenous effects such as dynamic coupling of parent-child helices and global helical interference. The research indicates that three-dimensional space evolves from long-term nesting and topological degradation of multiple independent helical dimensions. Dimension attenuation serves as the first principle of the universe for the generation of spacetime and matter. System inherent errors originate from same-layer helical interference, cross-dimensional coupling, and the dragging deflection of fundamental cosmic units induced by the superior parent helix. The introduction of the golden section power term can uniformly characterize the global interference intensity and effectively correct systematic deviations. This paper distinguishes between the original evolutionary model and the three-dimensional apparent geometric measurement model. The two expressions are self-consistent in origin and verify the rationality of the global helical dimension theory from the dual perspectives of evolutionary mechanism and spatial steady-state structure.
