Worked on the miraheze/mw-config repository to enhance the stability of moderation-related file upload handling. Focused on configuration management using PHP, the work involved correcting a variable name typo in GlobalSettings.php to ensure the upload stash max age setting was properly applied. This fix prevented premature deletion of uploaded files awaiting moderation, reducing the risk of edge cases and regressions in the moderation workflow. The approach emphasized code maintainability and clarity, with well-documented commit messages to aid future development. Although no new features were added during this period, the targeted bug fix contributed to more reliable and predictable configuration behavior.
