This work presents a zero-parameter structural formulation of neutrino mass relations. Using the fixed ratios=136, S=3124, with the inherited electron-sector quantities \ (\) and \ (mₑ\), the neutrino mass spectrum is represented by, ₍mₑ=B_ (n+ₙ), _=12S²[₂₀=12S⁴, =0, 1, 2. \]The branch factors are\₀=1, ₁=13R², ₂=1R, \ (²₈ ₉^2 (i-j) \) is used as a compact structural-transfer notation. The resulting absolute masses are, ₀0. 02246\, eV, , ₁0. 02405\, eV, , ₂0. 05529\, eV, \ m₀. 10180\, eV. corresponding mass-squared differences are\ m₂₁²7. 41810^-5\, eV², m₃₂²2. 47810^-3\, eV². \ The formulation introduces no neutrino-sector fitting parameters. The inputs \ (\) and \ (mₑ\) are inherited from the electron-sector structure, while the neutrino hierarchy is determined by the fixed ratios \ (R\) and \ (S\). A minimal Python implementation is provided for full reproducibility: https: //github. com/yasuotanakaresearch/zero-parameter-structure
