composition_violates_budget

formal source

  83    The composition law generates defect values that grow as
  84    cosh(2ⁿ·2η) − 1 ≥ 4ⁿ·(cosh(2η)−1), which exceeds any finite
  85    carrier budget for n large enough. -/

  92    If the Composition Closure Hypothesis holds, then every nontrivial
  93    zero of ζ(s) lies on the critical line Re(s) = 1/2.
  94
  95    Proof: Suppose ρ is off-critical. By CCH, every iterated defect is
  96    bounded by the carrier budget. But by the composition law, the
  97    iterated defects diverge. Contradiction. -/

 109    This packages the entire argument:
 110    - T5: RCL uniquely forces J
 111    - Bridge: ξ-symmetry = J-symmetry
 112    - Composition: RCL self-composition amplifies defect
 113    - Divergence: iterated defect is unbounded
 114    - Budget: carrier budget is finite
 115    - Conclusion: off-critical zeros are impossible -/
