 ## Source Repository
 
-No suitable source repository was found for Quintessential.
+| Field | Value |
+|-------|-------|
+| **Repository** | [librefonts/quintessential](https://github.com/librefonts/quintessential) |
+| **Commit** | `a3d26ff9183382b8379f368b41b07eb52f1bd193` |
+| **Confidence** | medium |
+| **Source Types** | ttx |
+| **Has config.yaml** | No |
 
-## What Was Done
+## Investigation Summary
 
-The following searches were performed:
+METADATA.pb for Quintessential had no source block. A source block was added pointing to the librefonts mirror repository.
 
-- Searched GitHub for "quintessential font" repositories — no font-related results were found.
-- Checked the `astigmatic` GitHub account (designer: Brian J. Bonislawsky DBA Astigmatic / AOETI) — the account exists but contains only 2 repositories (`astigmatic/pro` and `astigmatic/project1`), neither of which is a font source repository.
-- Searched for `AOETI` GitHub account — not found.
-- Searched GitHub repos with "Quintessential" in the name — results were unrelated software projects (SaaS platforms, CSS libraries, etc.), not font repositories.
-- Searched for "Quintessential astigmatic" in repository content — no relevant results.
+## Source Analysis
 
-No canonical upstream repository with font source files was found.
+The repository at https://github.com/librefonts/quintessential is a **librefonts mirror**. These repositories contain TTX (XML) files that were mechanically decompiled from the binary TTF fonts, not original design sources. They do not contain the original .glyphs, .ufo, .sfd, or other editable source files that the designer used to create the font.
+
+**Available source types**: ttx (decompiled from binaries)
+
+## Build Status
+
+This family is **not buildable** with gftools-builder from these sources. The TTX files in librefonts mirrors are binary round-trips, not design sources. No config.yaml was created because there are no compatible sources to build from.
 
 ## Notes
 
-- Designer: Brian J. Bonislawsky DBA Astigmatic (AOETI), contact: astigma@astigmatic.com
-- Astigmatic is a prolific type foundry with many fonts on Google Fonts, but they do not appear to maintain public source repositories on GitHub
+librefonts mirror with TTX sources. No Astigmatic repo found.

+
+## Actions Taken
+
+1. A `source { }` block was added to METADATA.pb with the librefonts mirror repository URL and commit hash.
+2. No config.yaml was created because the repository contains only TTX decompiled binary dumps, not original design sources suitable for gftools-builder.
