During October 2025, Dagmar Camilla Mørch focused on security hardening and repository hygiene for the cognitedata/toolkit project. She implemented a configuration management improvement by updating the .gitignore to exclude environment files generated by the cdf auth init command, thereby preventing accidental exposure of sensitive configuration data. This change, managed through Git, aligned the repository with security best practices and reduced the risk of secret leakage in both local and CI environments. While the work addressed a single feature and did not involve bug fixes, it demonstrated a targeted approach to repository security using configuration management and version control skills.
