+# Investigation Report: Headland One
+
+## Summary
+
+Headland One is a serif typeface designed by Gary Lonergan and mastered by Eben Sorkin (Sorkin Type Co), added to Google Fonts on 2012-05-09 via the initial commit of the repository. It has no source block in METADATA.pb. An upstream repository exists at `https://github.com/librefonts/headlandone`, but it contains only SFD source files (FontForge format) and TTX dumps -- no gftools-builder compatible sources (.glyphs, .ufo, or .designspace). No config.yaml is possible for this family.

+
+## Investigation Details
+
+### METADATA.pb Analysis
+
+The current METADATA.pb has no source block at all. It contains only:
+- Family name, designer ("Gary Lonergan"), license (OFL)
+- Category: SERIF
+- Date added: 2012-05-09
+- One font weight: HeadlandOne-Regular.ttf (400 normal)
+- Subsets: menu, latin, latin-ext
+
+No `repository_url`, `commit`, or `config_yaml` fields.
+
+### Google Fonts Git History
+
+The font was part of the massive initial commit of the google/fonts repository:
+
+1. **90abd17b4** - `Initial commit` -- Mar 7, 2015 (by Dave Crossland) -- this is when the git repo was created; the font was already in the Google Fonts catalog since 2012-05-09.
+2. **76adaf1d2** - `deploy: c7e274018...` -- this commit DELETED the Headland One files (likely a transient state in repo reorganization).
+
+The binary TTF file has only been touched by these two commits. There are no PR references or update commits.
+
+### Upstream Repository
+
+The upstream repo at `https://github.com/librefonts/headlandone` is cached at `fontc_crater_cache/librefonts/headlandone`.
+
+The repo has a single commit:
+- **c519360** - `update .travis.yml` -- Oct 17, 2014
+
+This is a typical `librefonts` mirror repo that contains:
+- TTX table dumps of the font files
+- SFD source files (`src/HeadlandOne-Regular-TTF.sfd` and `src/HeadlandOne-Regular-OTF.sfd`)
+- FONTLOG.txt, DESCRIPTION.en_us.html, OFL.txt, METADATA.json
+
+### Source Files
+
+The only source files in the repo are:
+- `src/HeadlandOne-Regular-TTF.sfd` -- FontForge SFD for TrueType version
+- `src/HeadlandOne-Regular-OTF.sfd` -- FontForge SFD for OpenType/CFF version
+
+These are SFD (FontForge) format files. The FONTLOG.txt mentions the original source was created in FontLab VBF format. No `.glyphs`, `.ufo`, or `.designspace` files exist. These SFD sources are not compatible with gftools-builder, so no config.yaml can be created.
+
+### Font Copyright and Origin
+
+From the FONTLOG.txt and binary metadata:
+- Designed by Gary Lonergan (garylonergan@hotmail.com)
+- Mastered by Eben Sorkin (sorkineben@gmail.com, Sorkin Type Co)
+- Copyright: "Copyright (c) 2011, Sorkin Type Co (www.sorkintype.com)"
+- Version 1.002 (April 2011)
+- The DESCRIPTION.en_us.html references Google Code as the source repository (historical -- Google Code was shut down)
+
+No override config.yaml exists in the google/fonts directory.
+
+## Conclusion
+
+The family has an identifiable upstream repo at `librefonts/headlandone` with only one commit. The sources are SFD-only (FontForge format), which are not compatible with gftools-builder. A source block can be added with the repository URL and commit hash, but no config.yaml is possible.
