January 2025 — root-project/web: Strengthened CI/CD safety and environment reliability by delivering two focused items in the repository. Data integrity protection in CI: added explicit exclusions to the AWS S3 sync command (excluding files/, download/, doc/) to prevent accidental deletion of data during automatic page synchronization. Deployment reliability: pinned the AWS CLI to version 1.36.40 across CI and delete-deployed PR workflows to ensure consistent CLI behavior across environments. These changes improve reproducibility, reduce deployment variation, and enable safer, faster iterations.
