Unified White Paper on W≡0 Global Topological Unified Field Theory: Global Topological Native Dimensions and International Unit System Unification

Project Affiliation: W≡0 Global Topological Unified Field Theory System Construction ProjectResearch Phase: Phase IV · Pre-Mathematical Foundation Layer Abstract Based on the first principles of four-dimensional topological spacetime in the W≡0 theory, this paper abandons the rootless phenomenological dimension system summarized from empirical observations in conventional physics, and establishes three exclusive native fundamental dimensions: topological length, topological time and topological action quantity. These three fundamental dimensions correspond strictly to three innate ontological attributes of cosmic topological noumenon, namely stability, flexibility and economy, and are intrinsically consistent with the internal mathematical logic of three core constants π, e and φ. This paper systematically defines the ontological connotation, general operation rules and global invariance principle of the three native dimensions, and completes the first-principle derivation of physical dimensions covering mechanics, electromagnetism, thermodynamics and quantum physics. Topological polarity intensity and topological fluctuation are uniformly classified as derivative concepts generated by the coupling of native dimensions, which clearly distinguishes the hierarchical boundary between noumenon essence layer and phenomenal manifestation layer. A minimalist, self-consistent and globally derivable system of topological native dimensions is finally constructed, which lays a standardized fundamental metrological benchmark for the first-principle traceability of fundamental physical constants, the construction of original generating equations and the overall framework of global unified field theory. This research inherits the core mathematical framework and ontological settings of General Outline of the Fourth-stage Pre-Mathematical Foundation Layer of W≡0 Global Topological Unified Field Theory (V1.0, DOI:10.5281/zenodo.20321570) and 4.01 Manual of Unified Universal Mathematical Tools (V1.0).
