Worked on the baton-sdk repository to enhance the reliability of C1Z artifact writes, focusing on backend development and robust error handling using Go. Addressed a critical issue where write operations could falsely report success by implementing explicit synchronization and close error checks across multiple code paths. This approach ensured that write-back failures, including those caused by OS-level IO errors or disk issues, were surfaced before reporting success, thereby improving data integrity. Leveraged static analysis to remove silent error masking and strengthen error propagation throughout the file handling lifecycle, resulting in more reliable artifact delivery and improved downstream consumer trust.
