Based on the core framework of Real-Virtual Dual Field Theory (RVDT), this paper proposes that lattice medium serves as the material substrate of cosmic spacetime, with a 1. 944 mm macroscopic lattice as its intrinsic elementary scale. By extending the classical fluid mechanics Bernoulli's principle to the global lattice medium system, this paper constructs a unified field potential dynamic equation covering both macroscopic celestial bodies and microscopic particles. By introducing four types of bulk correction coefficients — lattice nonlinear deformation, relativistic self-dragging, horizon topological fracture, and quantum topology — and supplementing the interface slip boundary coupling mechanism, the full-scale dynamic unification of ordinary planets, compact celestial bodies, rotating black holes and microscopic particles is achieved. To avoid the first-order deviation caused by the original microscopic particle scale approximation, this paper proposes three independent first-principles derivation paths for the global medium constant, starting from the intrinsic structure, wave propagation characteristics and field state conservation axiom of the 1. 944 mm lattice. All paths do not rely on macroscopic celestial body rotation observation data, nor do they introduce approximation assumptions of microscopic particle scales; instead, they directly establish the analytical relationship between the underlying intrinsic parameters and the global medium density from the theoretical axiom level. This paper clearly lists the basic parameters to be calibrated for each derivation path, substitutes the first-order approximate reference values into the macroscopic dynamic equation to complete the independent prediction of the Earth's equatorial rotation speed, and conducts a systematic attribution analysis of the prediction deviation. On this basis, this paper further derives the nature of microscopic particle spin, critical conditions for fission, secondary solidification criteria, and matter-antimatter annihilation mechanisms, clarifying the medium dynamic origin of energy release and confinement. This model does not require the introduction of strong and weak interactions or dark matter hypotheses. It can uniformly explain core physical phenomena such as gravity, particle spin, nuclear fission, and matter-antimatter annihilation solely through the vortex dynamics of continuous lattice medium and the axiom of field state conservation, providing a new continuous medium dynamic framework for the unification of macroscopic and microscopic physics. This preprint establishes the first-principles derivation framework for the global medium constant via three independent lattice-intrinsic paths, and introduces the quadruple bulk correction architecture ( (P), (v), (r), ₛ) together with the interface slip coefficient for unified field dynamics. The 1. 944 mm macroscopic lattice scale and its associated correction functions constitute the exclusive methodological foundation of the Real-Virtual Dual Field Theory (RVDT). Subsequent refinements of parameter calibration and experimental verification build upon this prior art.
