# Rum Raisin — Upstream Source Investigation

**Designer**: Astigmatic (Brian J. Bonislawsky)
**Model**: Claude Opus 4.6
**Date**: 2026-03-12

## Summary

No canonical upstream repository with UFO or Glyphs source files was found for Rum Raisin.

## Investigation

Rum Raisin was designed by Brian J. Bonislawsky DBA Astigmatic (AOETI). The DESCRIPTION.en_us.html and FONTLOG.txt direct contributors to contact `astigma@astigmatic.com`, but contain no upstream source repository links.

Searches were conducted for:
- `RumRaisin` by name on GitHub
- `astigmatic fonts`
- `astigmatic AOETI typeface`
- `Rum Raisin astigmatic`
- GitHub user `astigmatic`

The GitHub user `astigmatic` was found but only had two unrelated repositories (`astigmatic/pro`, `astigmatic/project1`). No font source repositories were associated with this account.

The only font repository associated with Astigmatic found via GitHub search was `googlefonts/SacramentoFont`.

The only repositories matching `RumRaisin` were:
- `librefonts/rumraisin` — a librefonts mirror (skipped per policy)
- Unrelated repositories (image processing, gaming projects)

## Conclusion

No canonical upstream repository with editable UFO or Glyphs sources was found for Rum Raisin. No source block was added to METADATA.pb.
