# Play — Source Metadata Investigation
+
**Model**: Claude Opus 4.6
**Date**: 2026-03-12
## Source Repository
-- **URL**: No source block present
-- **Commit**: N/A
-- **Status**: absent
-## What Was Done
-The existing source metadata was reviewed. No source block was found in METADATA.pb.
+| Field | Value |
+|-------|-------|
+| **Repository** | [googlefontdirectory-hg](https://github.com/googlefonts/googlefontdirectory-hg) |
+| **Commit** | `52f780bc9d197280a9f430574e179a5f233c56b6` |
+| **Source path** | `ofl/play/src/` |
+| **Buildable** | No — legacy format only (.sfd) |
+
+The font sources are in the **googlefontdirectory-hg** monorepo, a git mirror of the
+original Google Code Mercurial repository (`code.google.com/p/googlefontdirectory`)
+that was the canonical host for Google Fonts from 2010 to 2013.
+
+### Source files
+
+- **.sfd** (FontForge): Play-Regular-TTF.sfd, Play-Bold-TTF.sfd
+- **Metadata**: METADATA_comments.txt
+
+The only design sources are SFD files (FontForge format), which are not buildable with gftools-builder. No modern buildable sources (.glyphs, .ufo, .designspace) are available.
+
+## Investigation
-## Notes
Designer: Jonas Hecksher (e-types / Playtypes). Script: Latin, Cyrillic, Greek, Vietnamese. Category: SANS_SERIF / DISPLAY. Includes Regular and Bold weights.
+
+No source block was found in METADATA.pb. No canonical upstream GitHub repository was identified.
+
+## Conclusion
+
+No canonical upstream repository was found beyond the legacy googlefontdirectory-hg archive. Sources exist only as SFD files, which are not buildable with gftools-builder. No METADATA.pb changes were made.
