+# Yomogi — Source Metadata Investigation
+**Model**: Claude Opus 4.6
+**Date**: 2026-03-12
+
+## Source Repository
+- **URL**: https://github.com/satsuyako/YomogiFont
+- **Commit**: `8551d68706679b88ce6ff40e093a993e546e593e`
+- **Status**: Commit hash was added to existing source block
+
+## What Was Done
+The source block in METADATA.pb contained repository_url, files, and branch ("ver3.00") fields but was missing a commit hash. The latest commit on the ver3.00 branch was retrieved from the GitHub API and added to the source block. The hash was verified via `gh api repos/satsuyako/YomogiFont/commits/{hash}`.
+
+## Notes
+- Repository is maintained by Satsuyako.
+- The source uses a non-standard branch name "ver3.00" — this is an actual branch in the repository, not a tag.
+- Font supports cyrillic, japanese, latin, latin-ext, and vietnamese subsets.
