+
+## How URL Was Found
+
+The repository URL `https://github.com/librefonts/caesardressing` was added as part of the bulk source block addition in commit `9a14639f3` (2026-02-25). The librefonts GitHub organization hosts archived copies of many early Google Fonts projects. This is a standard librefonts archive repository containing TTX decompositions and metadata.
+
+## How Commit Was Determined
+
+The commit hash `fb212a606bc3f65a2b3d210c88e938f6090cff15` is the only commit in the repository (and therefore HEAD). It was made on 2014-10-17 with the message "update .travis.yml". This is a single-commit archive repository.
+
+Caesar Dressing was part of the initial commit (`90abd17b4`) in the google/fonts repository, meaning it was one of the earliest families added to Google Fonts. The librefonts repository is an archive of the original source material, not an active development repository.
+
+## Config YAML Status
+
+**No config.yaml exists** in the upstream repository and none is expected. The repository contains only:
+- `src/CaesarDressing-Regular-TTF.vfb` (FontLab format) - This is a legacy format not supported by gftools-builder.
+- TTX decompositions of the font in the root directory.
+- Standard metadata files (DESCRIPTION, FONTLOG, OFL, METADATA.json).
+
+There is no override `config.yaml` in the google/fonts family directory either.
+
+This family cannot be built with gftools-builder because the only source is in VFB (FontLab) format, which is not a supported input format. The font would need to be converted to Glyphs, UFO, or Designspace format before a config.yaml could be useful.
+
+## Verification
+
+- **Repository URL**: Valid. The librefonts/caesardressing repository exists and is accessible.
+- **Commit Hash**: Verified. The hash `fb212a606bc3f65a2b3d210c88e938f6090cff15` is the sole commit in the repository.
+- **Source Files**: VFB format only (legacy, not gftools-buildable).
+- **Font Origin**: This is a very early Google Fonts family (initial commit). The librefonts repo is an archive, not the original development repository.
+
+## Confidence Level
+
+**HIGH** for the repository URL and commit hash. The librefonts repo is a well-known archive of early Google Fonts sources. Since there is only one commit, there is no ambiguity about the commit hash.
+
+**Note**: This family is effectively "complete" in terms of source documentation, but cannot be made gftools-buildable without converting the VFB sources to a modern format.
+
+## Open Questions
+
+1. Is there any plan to convert the VFB sources to a modern format (Glyphs/UFO) for this family?
+2. The designer "Open Window" (Dathan Boardman, dathanboardman@gmail.com per the copyright string) may have the original editable sources in a different format.
