+| Field | Value |
+|-------|-------|
+| **Repository** | [googlefontdirectory-hg](https://github.com/googlefonts/googlefontdirectory-hg) |
+| **Commit** | `52f780bc9d197280a9f430574e179a5f233c56b6` |
+| **Source path** | `ofl/portersansblock/src/` |
+| **Buildable** | No — no design sources present |
+
+The font sources are in the **googlefontdirectory-hg** monorepo, a git mirror of the
+original Google Code Mercurial repository that was the canonical host for Google Fonts
+from 2010 to 2013.
+
+### Source Files
+
+- `PorterSansBlock-Regular.otf` — compiled binary, not a design source
+- `METADATA_comments.txt` — metadata comments
+
+No design source files were found — only a compiled OTF binary and metadata comments.
## Notes
+
Designer: Tyler Finck. Script: Latin. Category: DISPLAY (sans serif stroke).
+
+## Verdict
+
+**No usable source files in googlefontdirectory-hg.** Only a compiled OTF binary is present; no design sources (VFB, SFD, UFO, .glyphs) were included. No gftools-builder config is possible.
