# Ribeye Marrow — Source Metadata Investigation

**Model**: Claude Opus 4.6
**Date**: 2026-03-12

## Source Repository

No canonical upstream repository with UFO or Glyphs sources was found.

## What Was Done

The same search effort as for Ribeye was applied. Brian J. Bonislawsky of Astigmatic is the designer of both Ribeye and Ribeye Marrow. The GitHub accounts `ASTIGMATIC`, `astigmatic`, and `AOETI` were checked, with no repository found for Ribeye Marrow. No public source repository was identified for any Astigmatic fonts.

## Notes

Ribeye Marrow is a companion font to Ribeye, also by Brian J. Bonislawsky of Astigmatic, released in 2011. No public source repository was found.
