v1.5.1

Highlights

• Codex compatibility now uses a minimum floor of >=0.146.0; later releases are accepted and validated by native contract evidence.
• Luna remains the default route; Sol remains a bounded high-risk fallback.
• Added role-fitness scorecards, adjudicator Matrix reports, native dispatch evidence, and regression tooling.

Measured result

Native Sol transport completed successfully and stably, but switching quality/cost remains 5/10; the release does not claim a Sol switching promotion.
