  29/-- HierarchyDissolution establishes that masses don't receive
  30    Λ² radiative corrections. The electroweak scale is not
  31    fine-tuned — it emerges from ledger structure. -/

  36/-- **E-004 Structural**: The "electroweak scale problem" (why v ≈ 246 GeV
  37    and not M_Planck?) dissolves in RS. Masses come from φ-ladder rungs,
  38    not from Higgs VEV × Yukawa. The scale is E_coh · φ^r for appropriate
  39    r. No separate fine-tuning. Full v derivation: BLOCKED. -/
