+## Font Files in google/fonts
+
+- `ofl/fondamento/Fondamento-Regular.ttf` (87,160 bytes)
+- `ofl/fondamento/Fondamento-Italic.ttf`
+
+Both files were added in the initial commit `90abd17b4` (2015-03-07, "Initial commit" by Dave Crossland). The TTF blob hash (`d0489b293`) has remained unchanged since then -- the binaries have never been updated.
+
+## METADATA.pb Analysis
+
+The METADATA.pb on the `main` branch has no `source { }` block. A pending source block addition exists on branch `sources_info_2026-02-25` (commit `9a14639f3`), which adds:
+```
+source {
+ repository_url: "https://github.com/librefonts/fondamento"
+ commit: "92205310620ae12fc72d8dde6033cdc46ca07101"
+}
+```
+
+## Upstream Repository Analysis
+
+**Repository**: https://github.com/librefonts/fondamento (accessible, HTTP 200)
+
+The repository has exactly **one commit**:
+- `9220531` (2014-10-17) by `hash3g` -- "update .travis.yml"
+
+This is a typical "librefonts" repository created as part of the Google Fonts Font Bakery automation project circa 2014. The `hash3g` author was involved in this bulk repository creation effort.
+
+### Source Files Found
+
+The repository contains only legacy source formats:
+
+**In `src/` directory:**
+- `Fondamento-Regular-OTF.vfb` -- FontLab Studio binary (OTF outlines)
+- `Fondamento-Regular-TTF.vfb` -- FontLab Studio binary (TTF outlines)
+- `Fondamento-Italic-OTF.vfb` -- FontLab Studio binary (OTF outlines)
+- `Fondamento-Italic-TTF.vfb` -- FontLab Studio binary (TTF outlines)
+- `Fondamento-Regular.ai` -- Adobe Illustrator file
+- `Fondamento-Italic.ai` -- Adobe Illustrator file
+- Various `.otf.*.ttx` files (decompiled OTF table dumps)
+- `METADATA_comments.txt` -- subsetting/build comments
+- `VERSIONS.txt` -- lists "Version 1.000" for both fonts
+
+**In root directory:**
+- Various `.ttf.*.ttx` files (decompiled TTF table dumps)
+- `FONTLOG.txt`, `OFL.txt`, `DESCRIPTION.en_us.html`, `METADATA.json`
+- `.travis.yml` -- Font Bakery CI configuration
+
+### Build Configuration
+
+No `config.yaml` exists. The `.travis.yml` uses the old `fontbakery-build.py` build system (pre-gftools era). The source files are VFB (FontLab Studio binary format), which are **not compatible with gftools-builder**. There are no `.glyphs`, `.ufo`, or `.designspace` files.
+
+## Commit Verification
+
+Since the upstream repo has only a single commit (`9220531`), and the font was added to google/fonts in the initial commit (2015-03-07), this is straightforward. The upstream repo was created in October 2014, predating the google/fonts initial commit. The commit hash `92205310620ae12fc72d8dde6033cdc46ca07101` is the only commit in the repo and correctly represents the state of sources used for the fonts in Google Fonts.

+
+## Conclusion
+
+Fondamento is a calligraphic handwriting font designed by Brian J. Bonislawsky (Astigmatic) in 2011. The upstream repository at `librefonts/fondamento` is a single-commit Font Bakery repo containing only legacy VFB sources and TTX dumps. There are no gftools-builder compatible sources (.glyphs, .ufo, .designspace), so no config.yaml can be created.
+
+The repository URL and commit hash are verified with high confidence. The status is `missing_config` because there are no buildable source files that gftools-builder could use -- only VFB files that require FontLab Studio (proprietary software) to open.
+
+An override config.yaml is **not feasible** for this family because the upstream sources are VFB files, not a format supported by gftools-builder.
