+
+## How the Repository URL Was Found
+
+The repository URL `https://github.com/librefonts/abrilfatface` was identified from the upstream repo cache at `upstream_repos/fontc_crater_cache/librefonts/abrilfatface`. There is no `source { }` block in METADATA.pb at all. The `librefonts` organization on GitHub hosts TTX-decomposed mirrors of many early Google Fonts families, created by Dave Crossland.
+
+Note: TypeTogether (the credited designer) does not appear to have a public GitHub repository for Abril Fatface. The `librefonts/abrilfatface` repo is a legacy TTX mirror, not the original design source.
+
+## How the Commit Hash Was Identified
+
+The upstream repo has only a single commit: `5e899bfd997c34d1c2bd43ca9f94d2d0ded6346f` (dated 2014-10-17, message: "update .travis.yml"). This is the HEAD and only commit of the repository. The commit hash was selected as it represents the complete state of this single-commit repo.
+
+The last font-modifying commit in google/fonts is `90abd17b4f97` from 2015-03-07, with message "Initial commit" (part of the initial google/fonts repository setup). The font was added to Google Fonts on 2011-08-31 according to METADATA.pb, predating this repository's creation.
+
+## How Config YAML Was Resolved
+
+No `config.yaml` exists in the upstream repository. No override `config.yaml` exists in the google/fonts family directory (`ofl/abrilfatface/`).
+
+The upstream repo contains only legacy source formats:
+- `src/AbrilFatface-Regular-TTF.sfd` (FontForge SFD format)
+- `src/AbrilFatface-Regular.vfb` (FontLab VFB format)
+- Various `.ttx` decomposed table files
+- OTF-related TTX source files
+
+These source formats are not compatible with gftools-builder, which requires `.glyphs`, `.ufo`, or `.designspace` sources. A config.yaml cannot be meaningfully created without converting the sources to a modern format first.
+
+## Verification
+
+- Commit exists in upstream repo: Yes
+- Commit date: 2014-10-17 13:27:35 +0300
+- Commit message: "update .travis.yml"
+- Source files at commit: `src/AbrilFatface-Regular-TTF.sfd`, `src/AbrilFatface-Regular.vfb`, various `.ttx` files
+
+## Confidence
+
+**Medium**: The repository URL is confirmed and the commit is verified in the upstream repo. However, `librefonts/abrilfatface` is a legacy TTX mirror, not a true design source repository. TypeTogether (the credited designer) may have the original design sources in a different format or location. The font binary in google/fonts predates the librefonts repo (2011 vs 2014). The relationship between this repo and the original font production is indirect -- the repo was created as an archival/reproducibility effort, not as the original design source.
+
+## Open Questions
+
+- Does TypeTogether maintain an original source repository for Abril Fatface with `.glyphs` or `.ufo` sources?
+- Since the source formats (SFD/VFB) are not gftools-builder compatible, is there a plan to convert the sources to a modern format?
+- Should METADATA.pb be updated to include a `source { }` block pointing to this repo, even though it cannot be built with gftools-builder?
+- The font has been in Google Fonts since 2011 and has not been updated since the initial commit. Is an update planned?
