This technical note develops the linear cosmological perturbation framework of the Relativistic Coherent Vacuum Gravity Theory (rCVGT). It provides the intermediate theoretical layer connecting the covariant vacuum-field formulation of the theory to observable quantities such as the effective gravitational coupling and gravitational slip. The framework is intended as a foundation for numerical implementation and observational testing, complementing existing work on background cosmology and phenomenological applications of rCVGT.
