Ashley focused on stabilizing the build process for the simonmichael/stackage repository by addressing a critical compatibility issue in the Witness-related dependency graph. She removed restrictive version constraints and decoupled the monadology-witness and open-witness-witness packages, which had previously caused dependency cycles and build failures across environments. Using her expertise in build system management and dependency management, Ashley improved the maintainability and reliability of the build pipeline. Working primarily with YAML to manage configuration, she reduced CI churn and integration risk, enabling faster downstream adoption of Witness-enabled features. Her work demonstrated careful analysis and targeted resolution of complex build bottlenecks.
