During March 2025, Sam Smith focused on codebase cleanup and maintenance optimization for the conjure-cp/conjure-oxide repository. He removed the unused Kissat solver integration, including related files, dependencies, test suites, and solver adaptor implementations, to streamline the project and reduce ongoing maintenance risks. Working primarily in Rust, Sam applied skills in build system configuration, code refactoring, and dependency management to simplify the build and dependency graph. This targeted refactoring improved maintainability and onboarding by delivering a cleaner, more focused codebase. The work demonstrated disciplined repository hygiene and addressed potential regression surfaces, supporting safer releases and faster development cycles.
