# Ruluko — Upstream Source Investigation

**Designer**: Ana Sanfelippo, Angélica Díaz, Meme Hernández
**Model**: Claude Opus 4.6
**Date**: 2026-03-12

## Summary

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

## Investigation

Ruluko was designed by Ana Sanfelippo (Twitter: @anasanfelippo), Angélica Díaz (@angiecinadiaz), and Meme Hernández (@memepeca) as a typeface intended to aid those learning to read, with shapes related to handwriting styles used in Argentine schools.

Searches were conducted for:
- `Ruluko` by name on GitHub
- `Ruluko sanfelippo`
- `anasanfe` GitHub user
- `Ruluko typeface argentina`

The only repositories found matching `Ruluko` were:
- `librefonts/ruluko` — a librefonts mirror (skipped per policy)
- `google-fonts-bower/ruluko-bower` — a bower packaging repo (skipped)

No GitHub account was found for any of the three designers. The DESCRIPTION.en_us.html and FONTLOG.txt contain no upstream source repository links.

## Conclusion

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