During June 2025, Ryan Jensen-Clem focused on API maintenance for the spacetelescope/catkit2 repository, delivering a targeted cleanup of the service API. He removed obsolete protobuf attributes from service.proto and eliminated the unused m_PropertyDataStreamLinks member from ServiceProxy.h, reducing the API surface area and simplifying future development. Working primarily with C++ and protobuf, Ryan applied clean code and refactoring principles to streamline the codebase, making the API clearer for downstream consumers and easing onboarding for new developers. This work did not introduce new user-facing features but improved long-term maintainability and reduced the risk of regressions in future releases.
