Worked on the coq/opam repository to deliver three features focused on formal methods, OCaml development, and package management. Released the Coq MathComp Odd-Order 2.1.0 package with detailed opam metadata, including build, installation, and dependency information, and integrated the formal Feit-Thompson proof. Migrated rocq-native functionality to the OCaml repository, reducing maintenance overhead and improving downstream stability. Updated dependency constraints for coq-mathcomp-finmap to support a broader range of Coq versions, including development releases, while maintaining prudent upper bounds. Emphasized repository hygiene, clear commit traceability, and reproducible builds, resulting in improved CI reliability and a smoother developer experience.
