+## Trirong

+**Designer**: Cadson Demak
+
+### Upstream Repository
+
+The canonical upstream repository was found at **https://github.com/cadsondemak/trirong**, maintained by Cadson Demak (GitHub: cadsondemak), a type foundry based in Thailand. The DESCRIPTION.en_us.html in the Google Fonts repo explicitly linked to this repository.
+
+The repository contained the following structure at the investigated commit:
+- `source/` — 18 Glyphs source files, one per weight per style (e.g., `Trirong-100_Thin.glyphs`, `Trirong-400_Regular.glyphs`, etc.)
+- `fonts/` — compiled TTF files
+- `README.md`, `BRIEF.md`, `OFL.txt`
+
+The presence of Glyphs source files confirmed this as an eligible upstream with modern, editable sources.
+
+### Investigated Commit
+
+- **Repo**: https://github.com/cadsondemak/trirong
+- **Branch**: master
+- **Commit**: `0c1ce550d14a0a719ea49fcd6992cf5e1027dc6f`
+- **Date**: 2015-11-30
+- **Message**: "source and font files updated. fix nikahit and tone marks problem."
+
+The commit hash was verified via the GitHub API (`gh api repos/cadsondemak/trirong/commits/master`).
+
+### Status
+
+Source block was added to `METADATA.pb` pointing to the above repository and commit.
+
+### Notes
+
+Cadson Demak also maintains repositories for other Thai typefaces in Google Fonts (Anuphan, Bai Jamjuree, Chakra Petch, Charm, K2D, Kanit, Kodchasan, etc.) all under the `cadsondemak` GitHub organization.
