Ontology V8.4.4:T5: Unified Field Description and Synthesis within the V8 Framework (revised)

Building on Ontology V8.4.3, this paper completes the unified field description and synthesis within the V8 framework. It does not involve V7 and focuses only on the V8 framework. The main results are: (1) clarifying all fields in the V8 framework: the metric g_μν, the dark-energy field D, the granularity field φ, and the matter field ψ; (2) giving the decomposition of the total Lagrangian density and the explicit expressions of the six couplings; (3) deriving in detail the indirect coupling between the D and φ fields: G_eff → lP,eff → φ_P^eff; (4) deriving in detail the Lorentz-violating coupling between the D field and matter: Feynman rules, tree amplitudes, suppression mechanism, photon dispersion, gravitational-wave dispersion; (5) proving that the absence of φ–matter coupling is the unique choice satisfying the equivalence principle and fifth-force constraints; (6) giving the unified action, complete field equations, conservation laws, and Wheeler–DeWitt equation of the V8 framework; (7) completing the three-regime physical-behavior analysis and the full logical chain. This paper makes clear that the four fields in the V8 framework have distinct roles: D and φ have no direct coupling but are indirectly coupled through G_eff; the D–matter coupling provides the soft Lorentz violation; φ does not couple to matter; the low-energy theory is an effective field theory and the ultraviolet is asymptotically safe; the theory is self-consistent throughout. φ has a lower bound φ_P=1/l_P.
