+| License | OFL |
+| Date Added | 2012-09-30 |
+| Repository URL | https://github.com/librefonts/carroisgothicsc |
+| Commit Hash | `cd21c85aa57e4b1fc55eca2e31692cbd749e4e46` |
+| Branch | master |

+
+## How URL Found
+
+The repository URL `https://github.com/librefonts/carroisgothicsc` was recorded in the tracking data and added to the METADATA.pb source block in commit `9a14639f3` on branch `sources_info_2026-02-25` (not yet merged to main). This is a librefonts mirror repository, separate from the Carrois Gothic (non-SC) repo.
+
+## How Commit Determined
+
+The commit hash `cd21c85aa57e4b1fc55eca2e31692cbd749e4e46` is the HEAD (and only) commit of the upstream repository, with the message "update .travis.yml". The repository has only a single commit, so there is no ambiguity.
+
+The font was originally part of the initial google/fonts commit (`90abd17b4`). A hotfix was later applied in commit `e57e3eea9` (PR #875) by Marc Foley on 2017-05-08, updating the TTF from its original version to v1.002. This hotfix modified the binary and metadata but the upstream librefonts repo was not updated to reflect this.
+
+## Verification
+
+- **Commit exists in upstream repo**: Yes. `cd21c85` is the HEAD and sole commit.
+- **Repository accessible**: Yes, cached at `upstream_repos/fontc_crater_cache/librefonts/carroisgothicsc/`.
+- **Source files present**: The `src/` directory contains VFB files (FontLab Studio binary format): `CarroisGothicSC-Regular.vfb`, `CarroisGothicSC-Regular-OTF.vfb`, `CarroisGothicSC-Regular-TTF.vfb`. No open-format sources (.glyphs, .ufo, .designspace, .sfd) are available.
+- **TTX decomposed files**: The root directory and `orig/` directory contain TTX-decomposed font data, but these are not standard buildable sources for gftools-builder.
+
+## Config YAML Status
+
+**No config.yaml possible.** The upstream repository only contains VFB files (FontLab Studio proprietary binary format), which are not supported by gftools-builder. There are no SFD, Glyphs, UFO, or Designspace files that could be used as build sources.
+
+No override config.yaml exists in the google/fonts family directory either.
+
+## Relationship to Carrois Gothic
+
+Carrois Gothic SC is the small-caps variant of Carrois Gothic. Both were designed by Ralph du Carrois (Carrois Apostrophe) and share the same history:
+- Added in the initial google/fonts commit
+- Hotfixed by Marc Foley in May 2017 (PR #875 for SC, PR #874 for regular)
+- Upstream librefonts repos each have a single commit and contain VFB-only sources
+- Neither has gftools-builder-compatible sources
+
+## Confidence Level
+
+**HIGH** -- The commit hash is the only commit in the single-commit repository. The repository URL is a standard librefonts mirror. The situation is identical to Carrois Gothic (non-SC).
+
+## Open Questions
+
+- Same as Carrois Gothic: VFB sources would need conversion to an open format before any config.yaml could be created.
+- The hotfix PR #875 (2017) updated the binary in google/fonts but the upstream was never synced.
+- The status should remain `missing_config` as there are no gftools-builder-compatible sources.
