+## What Was Done
+
+The canonical upstream repository at `lettersoup/Ropa-Sans` was found via a GitHub API search. The `lettersoup` GitHub account is consistent with the designer Botjo Nikoltchev whose email domain `lettersoup.de` appears in the copyright string in METADATA.pb. The repository contains Glyphs source files for both the Regular and Italic weights. The latest commit hash was verified via the GitHub API. A `source` block was added to `METADATA.pb`.
+
+## Notes
+
+The repository also contains a `fonts/` directory with compiled OTF/TTF files and a `FONTLOG.txt`. The sources directory holds the Glyphs files. The repo was last updated in 2016.
