  13# T10 Necessity: Lepton Ladder is Forced
  14
  15This module proves that the muon and tau masses are **forced** from T9 (electron mass)
  16and the geometric constants derived in earlier theorems.
  17
  18## Goal
  19
  20Replace the two axioms in `LeptonGenerations.lean` with proven inequalities:
  211. `muon_mass_pred_bounds` — bounds on predicted muon mass
  222. `tau_mass_pred_bounds` — bounds on predicted tau mass
  23
  24## Strategy
  25
  26The lepton ladder is determined by:
  271. The electron structural mass (from T9)
  282. The step functions (from cube geometry and α)
  293. The golden ratio φ (from T4)
  30
  31The key insight is that the "steps" are combinations of:
  32- E_passive = 11 (passive cube edges)
  33- Faces = 6 (cube faces)
  34- W = 17 (wallpaper groups)
  35- α (fine-structure constant)
  36- π (from spherical geometry)
  37
  38All these are already derived from cube geometry and the eight-tick structure.

  52    The lepton ladder rungs {2, 13, 19} are the unique stable solutions for the
  53    three-generation torsion constraint in D=3.
  54    - Generation 1: Base Rung = 2 (forced by T9/electron linking)

  57    These rungs correspond to the residue classes {2, 5, 3} modulo 8,
  58    representing the three unique directions of the cubic voxel. -/

  81/-- **DEFINITION: Torsion Stability Constraint**
  82    A lepton ladder configuration is stable if:
  83    1. Generations occupy distinct residue classes in the Z_8 torsion group.
  84    2. The transitions between generations are forced by the fundamental
  85       topological gaps of the cubic voxel:
  86       - Δ₁ (Gen 1 → 2): Passive field edge count (E_p = 11).
  87       - Δ₂ (Gen 2 → 3): Dual face count (F = 6).
  88    3. The base rung is anchored by the electron linking (r₁ = 2). -/

 907Evaluation points are chosen so that c * log(phi) < eval_point (or >) holds
 908where c is the residue endpoint and log(phi) in (0.481211, 0.481212).
 909- 9.627 * 0.481212 = 4.63263, so exp upper at 4.6327 = exp(4) * exp(0.6327)
 910- 9.625 * 0.481211 = 4.63166, so exp lower at 4.6316 = exp(4) * exp(0.6316)
 911- 3.762 * 0.481212 = 1.81032, so exp upper at 1.8104 = exp(1) * exp(0.8104)
