Aidan Kwon updated the code ownership configuration in the kaiachain/kaia repository to reflect current team structure, focusing on governance rather than functional changes. By refining the CODEOWNERS file and removing outdated entries, Aidan improved the accuracy of pull request routing and notification scope, which streamlines review processes and clarifies accountability. The work involved disciplined use of Git version control and collaboration with cross-functional teams to ensure seamless transition. Although no application logic was modified, the update established a clear audit trail for future reference. This contribution leveraged skills in YAML configuration, repository management, and collaborative software development practices.
