v5.2.7 — Cost-ratio nomenclature reconciled
A single consistency fix against v5.2.6 (#4): the cost-ratio metric label is now Cv/Ci everywhere, matching the protocol's own formula and headline number.
The problem
The metric label was split between Ci/Cv and Cv/Ci. But the §4 formula is unambiguous:
Ratio = Cv($) / Ci
and the headline figure is ~3,300:1. So any line reading "Ci/Cv ratio … ~3,300:1" was mathematically self-contradictory — the reciprocal Ci/Cv ≈ 0.0003. Only Cv/Ci matches both the formula and the number ($50 ÷ $0.015 ≈ 3,333).

The §4 formula and Appendix A glossary were already correct and left untouched. Historical v5.2.6/v5.2.5 version-history entries are intentionally preserved.
