-## Repository Investigation
+## Investigation Details
 
-- **Checked cache**: `/mnt/shared/upstream_repos/fontc_crater_cache/` — no cached entry.
+- **Checked cache**: the upstream repo cache — no cached entry.
 - **GitHub organization**: The `paratype` GitHub organization exists but contains only two unrelated repositories — no font source repositories.
 - **GitHub search**: Searches for "PT Serif paratype OFL", "ptserif font", and "PT fonts paratype" returned no canonical designer-owned repository.
 - **Third-party mirrors**: No packaging mirrors were found for PT Serif specifically, unlike PT Sans.
 - **paratype.com**: No source repository link was found.
 
-## Context
+## Notes

Designed by Alexandra Korolkova under Paratype leadership, released in 2010. It covers Latin and Cyrillic scripts with Regular, Bold, Italic, and Bold Italic variants plus PT Serif Caption.
