## Investigation Details

### METADATA.pb Analysis

The current METADATA.pb has a fully populated source block:
- `repository_url`: `https://github.com/googlefonts/grechen-fuemen`
- `commit`: `4e4ac4caeac05708e6b3a05f0d91d1bb0476c045`
- `config_yaml`: `sources/config.yml`
- `branch`: `master`
- File mappings for OFL.txt, DESCRIPTION.en_us.html, and GrechenFuemen-Regular.ttf

### Google Fonts Commit History

1. **`ac4afe52d`** (2021-09-08) - "Grechen Fuemen: Version 1.010; ttfautohint (v1.8.3) added (#3796)" by Viviana Monsalve. This was the original onboarding commit, created via gftools-packager. The commit message explicitly references the upstream repo at commit `4e4ac4caeac05708e6b3a05f0d91d1bb0476c045`.
2. **`66f91f10f`** (2024-04-03) - "Merge upstream.yaml into METADATA.pb [skip ci]" by Simon Cozens. Added the source block with repository_url, file mappings, and branch from the upstream.yaml file.
3. **`19cdcec59`** (2025-03-31) - "[Batch 1/4] port info from fontc_crater targets list" by Felipe Sanches. Added `commit` and `config_yaml` fields to the source block.

### Upstream Repository Verification

The upstream repo at `googlefonts/grechen-fuemen` is cached at `upstream_repos/fontc_crater_cache/googlefonts/grechen-fuemen/`. It contains a single commit:

- **`4e4ac4c`** (2021-08-30) - "Family name typo fixed" by Viviana Monsalve

This is the only commit in the repo, confirming this is the exact commit used for onboarding. The commit predates the google/fonts merge date (2021-09-08), which is consistent.

### Config File Verification

The config file at `sources/config.yml` contains:
```yaml
sources:
  - GrechenFuemen.glyphs
familyName: "Grechen Fuemen"
buildVariable: false
```

The source file `sources/GrechenFuemen.glyphs` exists in the repo. This is a static (non-variable) font build.

### File Mapping Verification

The upstream.yaml from the onboarding commit maps:
- `OFL.txt` -> `OFL.txt`
- `DESCRIPTION.en_us.html` -> `DESCRIPTION.en_us.html`
- `fonts/ttf/GrechenFuemen-Regular.ttf` -> `GrechenFuemen-Regular.ttf`

All source files exist at the referenced paths in the upstream repo.

## Conclusion

The METADATA.pb source block is complete and correct. No changes are needed.
