## Summary

No canonical upstream repository with UFO or Glyphs sources was found for Stint Ultra Expanded. The only GitHub repository found was a librefonts mirror (`librefonts/stintultraexpanded`) containing only VFB (FontLab) sources.

## Designer

Astigmatic (Brian J. Bonislawsky, astigma@astigmatic.com)

## Search Results

- **librefonts/stintultraexpanded**: Mirror repository only. The `src/` directory contained `StintUltraExpanded-Regular-OTF.vfb`, `StintUltraExpanded-Regular-TTF.vfb`, and `StintUltraExpanded-Regular.vfb` — VFB only, no UFO or Glyphs sources.
- **astigmatic GitHub**: The `astigmatic` GitHub user had only two private/placeholder repos (`pro`, `project1`), no font repositories.
- No other repositories for this font were found on GitHub.

## Conclusion

No source block was added. The font sources only exist as VFB in a librefonts mirror, which is excluded per the investigation policy.
