-## What Was Done
+- **Repository**: `googlefontdirectory-hg`
+- **Commit**: `52f780bc9d197280a9f430574e179a5f233c56b6`
+- **Source path**: `quattrocentosans/src/`
+
+## Source Files
+
+The `quattrocentosans/src/` directory contains design sources in proprietary VFB format only, which cannot be built with gftools-builder:
+
+- **VFB** (FontLab, proprietary format, not buildable with gftools): QuattrocentoSans-Bold-OTF.vfb, QuattrocentoSans-Bold-TTF.vfb, QuattrocentoSans-Bold.vfb, QuattrocentoSans-BoldItalic-OTF.vfb, QuattrocentoSans-BoldItalic-TTF.vfb, QuattrocentoSans-BoldItalic.vfb, QuattrocentoSans-Italic-OTF.vfb, QuattrocentoSans-Italic-TTF.vfb, QuattrocentoSans-Italic.vfb, QuattrocentoSans-Regular-OTF.vfb, QuattrocentoSans-Regular-TTF.vfb, QuattrocentoSans-Regular.vfb
+- **OTF** (compiled binaries, not design sources): QuattrocentoSans-Bold.otf, QuattrocentoSans-BoldItalic.otf, QuattrocentoSans-Italic.otf, QuattrocentoSans-Regular.otf
+
+## Buildability
+
+Not buildable with gftools-builder. The VFB sources are in FontLab's proprietary format. Conversion to UFO or Glyphs format would be required before a reproducible build pipeline could be established.
