+## Source Repository
+- **URL**: https://github.com/fontworks-fonts/Train
+- **Commit**: `2972a9857a8332c2af86b221799558c177ba9012`
+- **Status**: Commit hash was added to existing source block
+
+## 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/fontworks-fonts/Train/commits/{hash}`.

+## Notes
+- Repository is maintained by Fontworks Inc.
