237Without closure, composing events would create orphan scales that
238can't be posted, violating the discrete ledger structure. -/

242/-- Full closure is too strong for arbitrary n, m.
243 But the MINIMAL closure (n=0, m=1 → k=2) is achievable
244 and forces the golden ratio. -/

252/-! ## Summary: The Derivation Chain
253
2541. J-cost is unique and additive (from RCL) ✓
2552. Ledger composition should be additive (to respect J-cost) ✓
2563. Scales form geometric sequence (discreteness) ✓
2574. Closure: 1 + r = r² (for composed scales to exist) ✓
2585. Therefore: r = φ ✓
259
260The constraint r² = r + 1 is now DERIVED from closure,
261which is motivated by ledger completeness. -/
