The Relational-Structural Framework identifies dark matter as the structural entropy of the causal graph — the information content of spacetime's topological degrees of freedom. In (D+1)-dimensional spacetime, the physical metric has (D+1)D/2 independent degrees of freedom. The scalar entropy field captures one. The remaining (D+1)D/2 1 are structural entropy, − which gravitates as cold dark matter. For D = 3: the predicted dark matter ratio is Ωstruct/Ωb = 5. The observed ratio Ωcdm/Ωb = 5.36 exceeds this by 0.36, which is attributed to massive neutrinos. This yields a zero-parameter prediction: Σmν = (Ωcdm/Ωb 5) × ωb × 93.14 eV = 0.76 eV (or 0.34 eV if the h² − correction applies — see Section 5). The prediction is verified against the Planck CMB power spectrum using the CLASS Boltzmann code and is falsifiable by DESI, Euclid, and CMB-S4 within the coming decade.
