Worked on kubeflow/pipelines to improve the reliability of Python packaging and build systems. Addressed a packaging issue by updating MANIFEST.in to ensure that requirements.txt and requirements-dev.txt are included in the Python source distribution, which resolved missing-file errors during wheel rebuilds in CI and downstream environments. This change enhanced build reproducibility and made the installation process more dependable for users and automated systems. The work focused on Python and packaging best practices, with clear traceability through commit and pull request references, supporting future maintenance and auditing. No new features were added, but a key bug affecting build reliability was fixed.
