Sierra Villarreal enhanced author metadata management for the lsst/lsst-texmf repository, focusing on improving attribution accuracy and metadata completeness. She updated the YAML-based authordb to add new contributors, including herself with correct SLAC affiliation, and introduced ORCID identifiers for better author disambiguation. Sierra also corrected author initials to align with established conventions and added the altaffil field to resolve CI issues, ensuring smoother continuous integration workflows. Her work leveraged configuration and data management skills to strengthen attribution governance, reduce ambiguity in author records, and improve downstream tooling, resulting in clearer contributor recognition and more reliable documentation management processes.
