Worked on the cda-tum/mqt-core repository to enhance the reliability and reproducibility of the CI/CD pipeline by introducing deterministic templating improvements. Focused on updating the GitHub Actions workflow, the developer pinned the templating action to a specific version of munich-quantum-toolkit/templates and locked it to exact commit hashes, ensuring that builds remain consistent over time. Clear in-code comments were added to document the versioning for auditability, making it easier to trace and verify changes. This work, implemented primarily in YAML and leveraging CI/CD best practices, reduced build variance and improved the overall traceability of the release process.
