I present the Six-Force Framework (6FM) v6.0, a density-regulated unification of the dark sector. This revision introduces the Dark Energy Sandwich (DES) model, which posits that dark energy in the vacuum "sandwiches" dark-sector effects against baryonic matter bubbles (galaxies). By coupling a covariant symmetron scalar field (φ) possessing a smooth hyperbolic tangent (tanh) transition matrix with a light axial-vector mediator (A′), I resolve eleven major cosmological and low-energy particle-physics anomalies through a single phase-boundary mechanism. This version explicitly incorporates the May 2026 discovery of ancient, massive, non-rotating galaxies as evidence for an omnidirectional void pressure ("squeezed") structural assembly mechanism rather than traditional spinning disks. I provide sharp, falsifiable predictions for a +3.83% excess in Coherent Elastic Neutrino-Nucleus Scattering (CEνNS) cross-sections, a bulge-dominated Galactic 511 keV gamma-ray annihilation signature, and a ~10⁻¹¹ m/s² topological CP-violating acceleration drift detectable in the upcoming Gaia DR4 wide-binary database. The framework unifies dark energy (void pressure), dark matter (interface fifth-force enhancement), baryogenesis (boundary CP-violation), and small-scale structure suppression (Sandwich-Regulated Jeans Mass) through one scalar field and one axial-vector mediator operating across a density-dependent phase boundary. All predictions are testable by experiments running in 2026–2027.
