+## Investigation Details
 
 UnifrakturCook was created by j. 'mach' wust as a modification of Peter Wiegel's font "Koch fette deutsche Schrift" (itself based on a 1910 typeface by Rudolf Koch). The font was originally published at http://unifraktur.sourceforge.net/cook.html.

 3. **j. 'mach' wust GitHub**: No GitHub account was identified for the designer.
 4. **Peter Wiegel**: Peter Wiegel (the original Koch Fraktur designer) maintains fonts at peter-wiegel.de but no GitHub presence was found.
 
-### Status
-
-No canonical upstream repository with UFO or Glyphs sources was found. The original sources are in FontForge SFD format at SourceForge. No source block was added to `METADATA.pb`.
-
-### Conclusion
-
 UnifrakturCook is hosted on SourceForge and its sources exist in FontForge SFD format. SFD sources are not eligible per the source block policy (which requires UFO or Glyphs format). The font predates the adoption of modern open font source workflows.
