   5# Higher-Order Voxel-Seam Corrections to α⁻¹
   6
   7This module formalizes the framework for computing higher-order corrections
   8to the fine-structure constant derivation, addressing the open ~8 ppm residual.
   9
  10## Background
  11
  12The RS derivation of α⁻¹ has three ingredients:
  131. Geometric seed: α_seed = 4π × 11 ≈ 138.230
  142. Gap weight: f_gap = w₈ · ln φ ≈ 1.198
  153. Curvature correction: δ₁ = -103/(102π⁵) ≈ -0.00330
  16
  17The additive formula: α⁻¹_add = α_seed - f_gap + δ₁ ≈ 137.035 (−8 ppm)
  18The exponential formula: α⁻¹_exp = α_seed · exp(-f_gap/α_seed) ≈ 137.037 (+6 ppm)
  19
  20CODATA: 137.035999206(11)
  21
  22## The Series Structure
  23
  24The full series is:
  25  α⁻¹ = α_seed − f_gap + Σ_{n=1}^∞ δ_n
  26
  27where δ_n is the n-th order voxel-seam correction on Q₃.
  28
  29Each δ_n is a finite combinatorial sum over n-fold face-wallpaper configurations
  30on Q₃, weighted by the Z₂⁵ half-period integration measure.
  31
  32## This Module
  33
  34Formalizes:
  35- The cube combinatorics (faces, wallpaper groups, face-wallpaper pairs)
  36- The first-order correction δ₁ = -103/(102π⁵)
  37- The framework for δ_n at arbitrary order
  38- Bounds showing the series is alternating and convergent
  39- The CODATA target as an explicit hypothesis
  40
  41## Status
  42
  43- PROVED: cube combinatorics, δ₁ structure, series framework
  44- OPEN: δ₂ computation (the key deliverable)
  45- HYPOTHESIS: convergence to CODATA
