+
+## Current METADATA.pb State
+
+The METADATA.pb has no `source { }` block. It contains only basic font metadata:
+- `name`: "Esteban"
+- `designer`: "Angelica Diaz"
+- `license`: "OFL"
+- `category`: "SERIF"
+- `date_added`: "2012-01-11"
+- Single font: Esteban-Regular.ttf (weight 400, normal style)
+
+## How URL Was Found
+
+The repository URL `https://github.com/librefonts/esteban` was identified from the `fontc_crater_cache` directory structure. The `librefonts` GitHub organization was created as part of the fontbakery project to host decomposed font sources (TTX tables) alongside original source files. This repo is a fontbakery-era mirror, not an original designer repository.
+
+The URL was verified accessible (HTTP 200).
+
+## How Commit Hash Was Identified
+
+The upstream repository contains only a single commit:
+
+- **35e274d** (2014-10-17): "update .travis.yml" by hash3g <hash.3g@gmail.com>
+
+This is the only commit in the repository, so it is trivially the correct reference. The commit created all files in the repo as a single initial import, including:
+- TTX decomposed tables of the TTF and OTF binaries
+- Source files: `src/Esteban-Regular.vfb`, `src/Esteban-Regular-OTF.vfb`, `src/Esteban-Regular-TTF.sfd`
+- `METADATA.json`, `FONTLOG.txt`, `OFL.txt`, `DESCRIPTION.en_us.html`
+- `.travis.yml` for fontbakery CI
+
+The font binary in google/fonts (`ofl/esteban/Esteban-Regular.ttf`) was added in the initial google/fonts commit `90abd17b4` (2015-03-07, Dave Crossland "Initial commit") and has never been updated since. The font reports Version 1.002.
+
+The upstream repo's `src/VERSIONS.txt` confirms: "Esteban-Regular.ttf: Version 1.002", matching the binary in google/fonts.
+
+## How Config YAML Was Resolved
+
+No `config.yaml` exists in the upstream repository. The source files are in legacy formats:
+- `src/Esteban-Regular.vfb` - FontLab VFB format (proprietary binary)
+- `src/Esteban-Regular-OTF.vfb` - FontLab VFB format (for OTF output)
+- `src/Esteban-Regular-TTF.sfd` - FontForge SFD format
+
+None of these formats (.vfb, .sfd) are compatible with gftools-builder, which requires `.glyphs`, `.ufo`, or `.designspace` sources. An override `config.yaml` cannot be created because there are no compatible source files to reference.
+
+The `.travis.yml` in the repo shows it used `fontbakery-build.py` for CI builds, which is a legacy build system that predates gftools-builder.
+
+## Verification
+
+- **Repository accessible**: Yes (HTTP 200)
+- **Repository clean**: Yes (`nothing to commit, working tree clean`)
+- **Branch**: master (single branch, up to date with origin)
+- **Binary match**: The font in google/fonts is Version 1.002, matching the upstream's `src/VERSIONS.txt`
+- **No updates since onboarding**: The font binary has only been touched once in google/fonts (initial commit 90abd17b4)
+- **No config.yaml possible**: Source formats (.vfb, .sfd) are incompatible with gftools-builder
+
+## Confidence
+
+**HIGH** -- The upstream repository has a single commit, making identification trivial. The version numbers match. However, this is a `librefonts` mirror repository, not the original designer's source repository. The original sources may have been in the old Google Font Directory (`googlefontdirectory/esteban/` as referenced in `src/METADATA_comments.txt`).
+
+## Notes
+
+- This font was added to Google Fonts on 2012-01-11 (per `date_added` in METADATA.pb), predating the librefonts mirror (2014-10-17) and the google/fonts initial commit (2015-03-07).
+- The designer is Angelica Diaz Rivera, contactable at angiecina@gmail.com per the copyright notice and FONTLOG.
+- The font is named after Jorge Alfredo Diaz Esteban, a writer whose manuscript style inspired the typeface's modulated strokes.
+- The `librefonts` repository is essentially an archival mirror with TTX-decomposed tables and legacy source files. It does not represent an active upstream development repository.
+- Building from source would require converting the .sfd or .vfb files to a modern format (.glyphs or .ufo) first.
+- A source block could be added to METADATA.pb pointing to this repo, but with status "missing_config" since no gftools-builder config is possible with the current source formats.
