Aidan Kwon updated the code ownership configuration in the kaiachain/kaia repository to better reflect the current team structure. By refining the CODEOWNERS file and removing outdated entries, Aidan improved the accuracy of pull request routing and notification scope without altering any functional code. This governance-focused change, implemented using Git and YAML, established a clear audit trail and enhanced repository maintainability. The update streamlined review processes and clarified accountability for future development cycles. While the work did not involve direct feature or bug development, it demonstrated careful version control practices and contributed to more efficient collaboration within the engineering team.
