Paper 1 of the Holographic Cosmology Series. Derives the master equation Λ (m) = (64π/3ℓP²) (m/mP) ⁴ connecting the cosmological constant to the lightest neutrino mass m₁. When the neutrino mass reaches 1. 76 meV, the expansion rate of the universe is fully determined — a zero-parameter prediction.
