+## What Was Done
+The source block in METADATA.pb contained repository_url, files, and branch ("master") fields but was missing a commit hash. The latest commit on the master branch was retrieved from the GitHub API and added to the source block. The hash was verified via `gh api repos/Kinutafontfactory/Yuji/commits/{hash}`.
