Worked on stabilizing automation and CI/CD workflows for the madeline-underwood/arm-learning-paths repository, focusing on restoring reliability to scheduled automation. Addressed a broken workflow by rolling back a GraphQL mutation argument type change in the last-reviewed-cron configuration, which had disrupted cron scheduling and automation. The targeted rollback, implemented in YAML and leveraging GitHub Actions, restored correct scheduling behavior while minimizing impact on other processes. This fix maintained development velocity and reduced the risk of downtime by ensuring that automated review scheduling continued to function as intended. The work demonstrated careful troubleshooting and a methodical approach to CI/CD pipeline maintenance.
