+## Investigation
+
+The METADATA.pb for Yatra One had no source block. The upstream repository was identified as cathschmidt/yatra-one, the designer Catherine Leigh Schmidt's own GitHub repository.
+
+### Source Types Available
+
+- **VFB** (FontLab): `source/masters/YatraOne.vfb`
+- **Build scripts**: Custom Python build pipeline (`source/build.py`, `source/config.py`)
+- **Feature files**: `source/family.fea` and related `.fea` files
+- **Binary TTF**: Hinted and unhinted TTFs in root directory
-## Summary
+### Buildability
-No upstream source repository with UFO or Glyphs sources was found for Yatra One. No source block was added to `METADATA.pb`.
+The repository uses a custom build pipeline (not gftools-builder compatible). The VFB source format requires FontLab for editing. No `config.yaml`, `.glyphs`, `.ufo`, or `.designspace` sources are present. Not directly buildable with gftools-builder.
-## Investigation Notes
+### Actions Taken
-Yatra One was designed by Catherine Leigh Schmidt. The font copyright states "Copyright 2014 The Yatra Project Authors" with no URL. Searches for "yatraone", "yatra one font", "yatra devanagari font", "yatra devanagari catherine", and "catherine leigh schmidt font" on GitHub returned no relevant results. No repository under `googlefonts/yatraone` was found.
+A source block was added to METADATA.pb pointing to commit `b991e49` (2016-09-26, "getting specimen in"), which is the latest commit in the repository and predates the google/fonts onboarding (2017-05-16).
-## Status
+## Build Configuration (Override)
-**Skipped** — no upstream source repository found; no UFO/Glyphs sources identified.
+An override `config.yaml` has been created in the google/fonts family directory, referencing `YatraOne_0.ufo` from `cathschmidt/yatra-one`. This is a best-effort starting point for reproducible builds — the shipped binary was likely built with different tool versions and may not match exactly.
