Abstract: Based on the "Spatial Medium" model v1.0, this paper constructs a Lorentz-covariant dynamical non-metric field theory. By introducing a scalar field $\phi$ (representing the trace of the non-metric tensor $Q$) with a self-interaction potential $V(\phi)$ and nonlinear derivative coupling terms (Galileon terms), the discontinuity at the critical acceleration $a_0$ present in v1.0 is resolved. The evolution equation $a_0(t) = c H(t) / 2\pi$ is derived, and the intrinsic equivalence between $a_0$ and the cosmological constant $\Lambda$ is established. Via the Vainshtein screening mechanism, the model provides a consistent description across all scales, from the strong-field regime in the Solar System to the weak-field cosmology.
