+# Investigation Report: Habibi
+
+## Summary
+
+Habibi is a high-contrast serif typeface designed by Magnus Gaarde and mastered by Eben Sorkin (Sorkin Type Co). It was added to Google Fonts on 2011-12-19 as part of the initial commit of the google/fonts repository. The upstream repository at `librefonts/habibi` is a legacy mirror (originally from Google Code) containing only VFB and SFD source files -- no gftools-builder compatible sources exist.

+## Investigation Details
+
+### METADATA.pb Review
+
+The current METADATA.pb in `ofl/habibi/` has no `source { }` block. Key fields:
+- Name: "Habibi"
+- Designer: "Magnus Gaarde"
+- License: OFL
+- Date added: 2011-12-19
+- Copyright: "Copyright (c) 2011, Sorkin Type Co (www.sorkintype.com eben@eyebytes.com)"
+
+### Google Fonts Repository History
+
+The font file history in google/fonts shows only metadata-related changes after the initial commit:
+
+| Commit | Date | Description |
+|--------|------|-------------|
+| `90abd17b4` | 2015-03-07 | Initial commit (contains Habibi-Regular.ttf) |
+| `480630de3` | -- | Tentative update to METADATA.pb textprotos |
+| `27f377ab0` | -- | Update copyright field in METADATA.pb |
+| `633ebadbf` | -- | Add language support metadata |
+| `701bd391b` | -- | Undo rollback, remove languages from METADATA |
+
+The font binary (`Habibi-Regular.ttf`) has not been updated since the initial commit. This is a legacy font from 2011 that predates the modern gftools-packager workflow.
+
+### Upstream Repository Analysis
+
+The repository at `https://github.com/librefonts/habibi` is a `librefonts` mirror, likely auto-generated from the old Google Code font directory. It contains a single commit:
+
+- **Commit**: `1c3eb606631e9da373f1017f7972765a7ab32bd5` (2014-10-17)
+- **Author**: hash3g
+- **Message**: "update .travis.yml"
+
+The repository contains TTX decompositions of the font alongside source files:
+
+**Source files found:**
+- `src/Habibi-Regular.vfb` -- FontLab VFB format (proprietary binary)
+- `src/Habibi-Regular-TTF.sfd` -- FontForge SFD format
+
+**No gftools-builder compatible sources found** -- no `.glyphs`, `.ufo`, or `.designspace` files. The VFB format requires FontLab (proprietary) and the SFD format is a FontForge format not supported by gftools-builder/fontmake.
+
+The repository also includes a `.travis.yml` for fontbakery CI and a `FONTLOG.txt` documenting the design history.
+
+### Build Configuration
+
+No `config.yaml` exists in the upstream repository, and none can be created because the source files (VFB/SFD) are not compatible with gftools-builder. The font was mastered manually from FontLab VFB to TTF in December 2011.
+
+## Conclusion
+
+Habibi is a legacy font from 2011 with only VFB/SFD source files in the `librefonts/habibi` mirror repository. No gftools-builder configuration is possible because the source formats are incompatible. The font has never been updated since its initial inclusion.
+
+### Recommended METADATA.pb source block
+
+```
+source {
+ repository_url: "https://github.com/librefonts/habibi"
+ commit: "1c3eb606631e9da373f1017f7972765a7ab32bd5"
+}
+```
+
+Note: No `config_yaml` field is possible because the repository only contains VFB and SFD source files, which are not compatible with gftools-builder.
+
+### Status: `no_config_possible`
+### Confidence: HIGH
