Replication Package for "Active Today, Reused Tomorrow? A Retrospective Cohort Study of Repository Activity on the Hugging Face Hub"

This record contains the replication package for "Active Today, Reused Tomorrow? A Retrospective Cohort Study of Repository Activity on the Hugging Face Hub." The study examines whether recent post-launch substantive repository activity on the Hugging Face Hub is associated with later downstream uptake, using a retrospective cohort design with repeated monthly checkpoints. The package includes the analysis-ready SQLite database, frozen derived outputs underlying the reported results, data-collection and analysis scripts, commit-materiality and commit-taxonomy validation artifacts, verification tests, and detailed documentation. It supports direct inspection of the reported evidence, automated verification of the released artifact, and a full computational rerun of the paper-facing analyses. The complete integrated working database and transient extraction data are not redistributed because of their size. Their construction, provenance, and relationship to the released analysis database are documented in the package.
