This paper completes a series of earlier papers on the Cosmological Constant as compressible fluid-like zeropoint energy, which acts as a 2nd order perturbation in the stress-energy tensor; this preceded an earlier sketch for a means for Dark-Energy to gravitate. We suggest a replacement to ad-hoc MOND type theories with the theory developed herein, in the light of recent DESI and JWIST discoveries, with a fully covariant version of our earlier gravitating dark-energy model: we show that dark-energy can gravitate if it is considered to be in compression by tidal effects; also it sets a natural cusp-like size limit to galaxies and clusters. A relation is suggested between the slope of the galactic rotation curve and the slope of the dark-energy/matter zone is found too. An earlier proof by the author that MOND type theories are not Heisenberg Uncertainty Principle compatible is cited here. Finally we ask if an extra-repulsive form of dark-energy may prevent collapse to singularity in Black hole solutions. All-in-all, this paper is a semi-classical treatment of gravity with vacuum corrections that might manifest on the large-scale.Keywords: Action, Cosmological Constant, Covariance, Dark-Matter, DESI, Gravitating Dark-Energy, Uncertainty Principle, JWIST, ΛCDM, MOND, Renormalisation Group, Rotation Curves, Singularities
