Teena Francis focused on security hardening within the CI/CD pipeline for the qld-gov-au/qgds-bootstrap5 repository during July 2025. She addressed a permissions issue in the Chromatic workflow by updating the chromatic.yml configuration, ensuring that the workflow operated with least-privilege access. This change restricted repository content access to read-only during automated Chromatic builds, reducing the risk of over-privileged CI jobs. Teena implemented the update using YAML and GitHub Actions, delivering the fix in a single, targeted commit to maintain production stability. Her work demonstrated a careful approach to CI security, emphasizing risk reduction and operational reliability in deployment workflows.
