-# Investigation Report: Hermeneus One
+# Hermeneus One -- Source Investigation
-## Summary
+**Model**: Claude Opus 4.6
+**Date**: 2026-03-03
-Hermeneus One is a Grecian-style serif display font designed by Pablo Impallari and Rodrigo Fuenzalida. It was added to Google Fonts in the initial commit (2015-03-07) and has never been updated since. The upstream repository at `librefonts/hermeneusone` contains only VFB (FontLab binary) source files and TTX dumps -- no gftools-builder compatible sources (.glyphs, .ufo, .designspace). A config.yaml cannot be created because there are no buildable sources.

-## Investigation Details
+| File | Format | Buildable |
+|------|--------|-----------|
+| `HermeneusOne-Regular.vfb` | FontLab binary | No |
+| `HermeneusOne-Regular-OTF.vfb` | FontLab binary | No |

-### Upstream Repository
+The source directory contains three VFB files (FontLab proprietary binary format) and a compiled OTF binary. VFB files cannot be processed by gftools-builder, fontmake, or fontc. No `.glyphs`, `.ufo`, or `.designspace` files exist.
-The upstream repository is https://github.com/librefonts/hermeneusone, cached locally at `upstream_repos/fontc_crater_cache/librefonts/hermeneusone/`. The repo has only one commit (`20a3262`, dated 2014-10-17), which is a Travis CI configuration update that also constitutes the initial upload of all files.
+## Designer
-The repo is a `librefonts` archive-style repository containing:
-- TTX table dumps of the TTF font (split per table)
-- `src/HermeneusOne-Regular.vfb` -- FontLab VFB source
-- `src/HermeneusOne-Regular-OTF.vfb` -- OTF variant VFB source
-- `src/HermeneusOne-Regular-TTF.vfb` -- TTF variant VFB source
-- `src/HermeneusOne-Regular.otf.*` -- TTX dumps of OTF tables
-- `FONTLOG.txt` -- references http://www.impallari.com/projects/overview/hermeneus
-- `METADATA.json` -- legacy metadata
-- No `.glyphs`, `.ufo`, or `.designspace` files
-- No `config.yaml` or `config.yml`

-### Onboarding History
+Hermeneus One is a Grecian-style serif display font. The FONTLOG.txt references the project page at `http://www.impallari.com/projects/overview/hermeneus`.
-The font binary was added to google/fonts in the initial commit `90abd17b4` (2015-03-07, author: Dave Crossland). The font file (`HermeneusOne-Regular.ttf`, 132940 bytes) has never been modified since.
+## librefonts Mirror
-The METADATA.pb copyright states: "Copyright (c) 2012, Pablo Impallari (www.impallari.com|impallari@gmail.com) and Rodrigo Fuenzalida (www.rfuenzalida.com), with Reserved Font Name Hermeneus."
+A mirror exists at `https://github.com/librefonts/hermeneusone` with a single commit:
+- `20a3262` (2014-10-17) by hash3g: "update .travis.yml"
-### Source Block Status
+The repo contains the same VFB sources, TTX table dumps, and metadata files. It adds no additional design sources beyond what is in googlefontdirectory-hg.
-The current HEAD of google/fonts has no source block in METADATA.pb for this family. A source block was added in commit `9a14639f3` (2026-02-25, "Add source blocks to 602 more METADATA.pb files") on a branch, pointing to `librefonts/hermeneusone` at commit `20a3262831635f7f246ec54caf68abd760f2f582`.
+## google/fonts History
-### Source File Analysis
+The font binary was added in the initial commit `90abd17b4` (2015-03-07, author: Dave Crossland). The font file (`HermeneusOne-Regular.ttf`, 132940 bytes) has never been modified since.
-All source files are in VFB format (FontLab proprietary binary). VFB files cannot be processed by gftools-builder, fontmake, or fontc. To build fonts from these sources, one would need to:
-1. Convert VFB to UFO or .glyphs format using FontLab or vfb2ufo
-2. Create a config.yaml referencing the converted sources
+## Build Configuration
-Since the upstream repo has no buildable sources, no config.yaml can be created.
-
-### Original Design Source
-
-The FONTLOG.txt references the project page at `http://www.impallari.com/projects/overview/hermeneus`. The original design was by Pablo Impallari and Rodrigo Fuenzalida, with hinting by Igino Marini (v1.2, November 2011).

-## Conclusion
-
-**Status: no_config_possible**
-
-The upstream repository `librefonts/hermeneusone` is a valid archive of the font sources, but it contains only VFB (FontLab binary) files. No gftools-builder compatible sources exist, making it impossible to create a config.yaml for automated building. The source block should reference this repo at commit `20a3262` with no `config_yaml` field. The font has never been updated since the initial google/fonts commit.
+- **No config.yaml** exists in any known repository
+- **No override config.yaml** exists in the google/fonts family directory
+- All source files are VFB format (FontLab proprietary binary), not supported by gftools-builder
+- To build from these sources, VFB would need conversion to UFO or .glyphs format first
+- A config.yaml cannot be created for this family with the current source formats
