+# Oxygen Mono — Source Metadata Investigation
+
+**Model**: Claude Opus 4.6
+**Date**: 2026-03-12
+
+## Summary
+
+Oxygen Mono is the monospace companion to the Oxygen font family, designed by Vernon Adams (GitHub: vernnobile). It was added to Google Fonts on 2012-09-08 and shares its upstream repository with Oxygen.
+
+## Designer
+
+Vernon Adams (vern@newtypography.co.uk) maintains the canonical upstream at https://github.com/vernnobile/oxygenFont. See the Oxygen investigation for full designer details.
+
+## Canonical Upstream Repository
+
+The canonical upstream repository is **vernnobile/oxygenFont**: https://github.com/vernnobile/oxygenFont
+
+The `Oxygen-Monospace/src/` directory contains:
+- `OxygenMono-Regular.ufo/` — UFO source directory (confirmed: contains `features.fea`, `fontinfo.plist`, `glyphs/`, `lib.plist`, `metainfo.plist`)
+- `OxygenMono-Regular.sfd` — FontForge SFD source file
+- `OxygenMono-Regular-unhinted.ttf` — unhinted TTF build artifact
+
+The presence of the UFO source confirms this is a canonical, buildable open-source repository.
+
+Latest commit: `62db0ebe3488c936406685485071a54e3d18473b`
