  "abstract": "Newtonian gravity is extraordinarily successful in the weak-field regime, but recovering its inversesquare law alone does not explain why the same gravitational environment also shifts clocks, bends light, delays electromagnetic signals, and drives post-Newtonian orbital precession. To address this problem, we develop Physical-Vacuum Response Gravity (PVRG), a unified effective theory on fixed Minkowski spacetime that contains both a Newtonian source mechanism and a static relativistic probe sector. Matter is represented by localized oscillatory vacuum defects whose complete backgroundsubtracted energy defines inertia and weak response. A source removes a correlated component of an otherwise isotropic directional response; scalar energy is restored through statistically backgroundized return, while the source-test directional correlation is not restored in the ideal limit. Reciprocity and universal response per unit complete mass yield an inverse-square interaction, compositionindependent free fall, and, after Planck normalization and linear superposition, the Newtonian potential and Poisson equation. The same potential then defines one dimensionless probe-response strength. Two universal temporal and spatial phase-momentum response functions are coupled to both material and electromagnetic probes. An incremental complete-energy law fixes the nonlinear temporal coefficient, while conservative vacuum-response redistribution motivates a longitudinal reciprocity condition fixing the leading spatial coefficient. The closed PVRG response reproduces the gravitational frequency shift, light deflection, Shapiro delay, and perihelion advance without observable-specific fitting. A minimal nonlinear continuation further gives a conditional second-order solar-limb-scale deflection coefficient differing from the general-relativistic benchmark by about 0.7 microarcseconds. PVRG is explicitly an effective theory at this stage: several source and probe closures still require derivation from a common microscopic vacuum-field action.",
