   7# PMNS Radiative Correction Derivation
   8
   9This module derives the integer coefficients (6, 10, 3/2) appearing in the
  10PMNS mixing angle predictions from geometric principles.
  11
  12## The Predictions
  13
  14- sin²θ₁₃ = φ⁻⁸ (reactor weight, from 8-tick octave closure)
  15- sin²θ₁₂ = φ⁻² − 10α (solar weight with radiative correction)
  16- sin²θ₂₃ = ½ + 6α (atmospheric weight with radiative correction)
  17
  18## Derivation of the Integers
  19
  20### The Coefficient 6 (Atmospheric)
  21
  22The atmospheric mixing is governed by the **cube topology**:
  23- A 3-cube has exactly 6 faces
  24- Each face represents a "passive" mode in the Z-projection
  25- The radiative correction is proportional to the face count
  26- Therefore: atmospheric_correction = 6 × α
  27
  28### The Coefficient 10 (Solar)
  29
  30The solar mixing involves **edge-face counting**:
  31- A 3-cube has 12 edges and 6 faces
  32- The solar sector couples edges to faces via the 2-step torsion
  33- The effective passive count is: 12 - 2 = 10 (subtracting the active pair)
  34- Therefore: solar_correction = 10 × α
  35
  36### The Coefficient 3/2 (Cabibbo/CKM)
  37
  38The Cabibbo angle correction involves **vertex-edge duality**:
  39- A 3-cube has 8 vertices and 12 edges
  40- The quark sector couples via the face-diagonal torsion
  41- The effective ratio is: 6 faces / 4 (vertex-edge slots) = 3/2
  42- Therefore: cabibbo_correction = (3/2) × α
  43
  44## Summary
  45
  46All integer coefficients derive from the **cube topology** of the 3D voxel ledger:
  47- Faces (F = 6): atmospheric correction
  48- Edges - 2 (E - 2 = 10): solar correction
  49- Faces / 4 (F/4 = 3/2): Cabibbo correction
  50
  51This is **parameter-free** because the cube geometry is fixed by D = 3.
