Easy path
> Review this change deeply, settle findings, and merge it.The delivery route runs the Thermos pair against the same frozen diff and relevant source context.
What happens
- The correctness lens traces breakage, security, developer experience, and feature-leak risks.
- The code-quality lens looks for duplicate helpers, structural drift, and avoidable complexity.
- Findings are synthesized, real findings are fixed, and the affected checks run again.
- The merge-settlement hook keeps merge authority aligned with the latest review evidence.
