Derives the CCEGA critical density ρc from quantum chromodynamics. The MIT bag model with perturbative QCD corrections gives ρₜrans = 6. 9–7. 9 ρₙuc for B^1/4 = 210–220 MeV and αₛ = 0. 3–0. 5 — values within the experimentally accepted range — in precise agreement with the CCEGA preferred value ρc ≃ 7 ρₙuc from PSR J0952−0607. The gravitational hard threshold of CCEGA and the hadron-quark phase transition of QCD are identified as the same critical point. CCEGA therefore has zero free parameters. Includes a prediction for lattice QCD: the cold quark-hadron transition should occur at ∼7 ρₙuc, currently beyond ab-initio reach due to the sign problem.
