Worked on the RosettaCommons/foundry repository to restore and stabilize symmetry-related functionality, focusing on long-term maintainability and reliability. Addressed a critical bug by reverting unstable symmetry configuration changes to a previously stable state, ensuring consistent behavior for users. Introduced a standardized JSON configuration file to streamline future updates and reduce the risk of errors in symmetry management. Enhanced documentation to clarify supported symmetry types, which helped minimize user confusion and support overhead. Utilized Python for code improvements, including the removal of unused functions and targeted optimizations, resulting in cleaner, more efficient code and a more robust foundation for ongoing development.
