Absolute Neutrino Mass Scale from a Parameter--Free Relational Anchor

The absolute mass scale of neutrinos remains one of the most profound open questions in particle physics. In this letter, we derive the exact neutrino mass spectrum without free parameters, utilizing the Relational Emergence of SpaceTime (REST) framework. In REST, physical scales emerge from discrete bipartite graph combinatorics rather than continuous fields. By anchoring the neutrino sector to the symmetric electromagnetic limit (m_* = 8⁴ mₑ 11. 59 meV) and incorporating the maximal parity violation of the weak interaction as a topological filter (chiral frustration), we analytically derive the mass exponent q = 2. 5. Inserting this into a generalized Hölder mean over the PMNS matrix yields the precise neutrino masses (m₁, m₂, m₃) = (2. 27, 8. 91, 49. 6) meV. This predicts a total mass sum of m_ = 0. 0608 eV—in strict agreement with current cosmological bounds—and unambiguously selects the normal mass ordering.
