-## Summary
+## Source Repository
-No canonical upstream repository with UFO or Glyphs sources was found for the Sarina font family. The font was designed by James Grieshaber and published by Sorkin Type Co. Searches of GitHub did not locate a public source repository.
+The `googlefontdirectory-hg` monorepo (the historical Google Font Directory Mercurial archive) contains files for this family.

+- **Repository**: `googlefontdirectory-hg`
+- **Commit**: `52f780bc9d197280a9f430574e179a5f233c56b6`
+- **Source path**: `sarina/src/`
+
+## Source Files
+
+The `sarina/src/` directory contains design sources in VFB (FontLab) and SFD (FontForge) formats, neither of which can be built with gftools-builder:
+
+- **VFB** (FontLab, proprietary format, not buildable with gftools): Sarina-Regular.vfb
+- **SFD** (FontForge, not buildable with gftools-builder): Sarina-Regular-TTF.sfd
+- **OTF** (compiled binaries, not design sources): Sarina-Regular.otf
+
+## Buildability
+
+Not buildable with gftools-builder. The sources are in VFB (FontLab proprietary) and SFD (FontForge) formats. Neither format is supported by gftools-builder. Conversion to UFO or Glyphs format would be required.
