+## Source Files
-## Summary
+The source directory contains: 2 VFB files (FontLab, proprietary format); 3 SFD files (FontForge format); 2 compiled binaries (OTF/TTF, not design sources).
-No canonical upstream repository with UFO or Glyphs sources was found for Stoke. The font was created by Nicole Fally for Sorkin Type Co.
+Neither VFB (FontLab, proprietary) nor SFD (FontForge) formats are supported by gftools-builder. These sources are **not directly buildable** with the current open-source pipeline.

## Designer
- **EbenSorkin GitHub**: EbenSorkin (Eben Sorkin of Sorkin Type Co.) hosted many font repositories but Stoke was not among them.
- The font was created in 2012 and Stoke appears to have no public source repository.
- Nicole Fally had no identifiable GitHub presence.
-
-## Conclusion
-
-No source block was added. No canonical repository with UFO or Glyphs sources was found.
