+# Investigation Report: Elsie
+
+## Family Details
+- **Family name**: Elsie
+- **Designer**: Alejandro Inler (with Ana Sanfelippo)
+- **License**: OFL
+- **Category**: DISPLAY / SERIF
+- **Date added to Google Fonts**: 2012-11-12
+- **Weights**: Regular (400), Black (900)

+
+## METADATA.pb Source Block (Current State)
+
+```
+source {
+ repository_url: "https://github.com/googlefonts/elsiefont (404)"
+}
+```
+
+The current `repository_url` includes a literal `(404)` annotation appended by Simon Cozens in PR #7160 ("More upstreams (e,f)"), merged 2024-01-16. This is not a valid URL -- it was a note that the repository was already gone at the time it was recorded.
+

+- **No `.glyphs`, `.ufo`, or `.designspace` files** are available anywhere.
+- **No `config.yaml`** exists in the repo.
+
+## Onboarding History in google/fonts
+
+### Initial commit (2015-03-07)
+- **Commit**: `90abd17b` -- "Initial commit" by Dave Crossland
+- **Note**: This was a bulk initial import; no upstream reference recorded.
+
+### PR #884 (2017-05-08) -- hotfix-elsie: v1.002 added
+- **Author**: Marc Foley (m4rc1e)
+- **Changes**: Updated both `Elsie-Regular.ttf` (41044 -> 40956 bytes) and `Elsie-Black.ttf` (42424 -> 42216 bytes), plus `DESCRIPTION.en_us.html` and `METADATA.pb`.
+- **No upstream reference** in commit body or PR description.
+
+### PR #2754 (2020-10-28) -- [hotfix] ofl/elsie/Elsie-Regular.ttf updated
+- **Author**: Rosalie Wagner (RosaWagner)
+- **Changes**: Updated only `Elsie-Regular.ttf` (40956 -> 38936 bytes).
+- **Purpose**: Fix issue #515 (fi/fj ligature problem) by removing f_i and f_j ligatures, version bumped from 1.002 to 1.003.
+- **Note**: "few FAILS since it's an old font" -- hotfix was done directly on the binary, not from sources.
+
+### PR #7522 (2024-04-08) -- Hotfix fi and fj for ElsieSwashCaps-Regular.ttf
+- **Author**: Yanone
+- **Key quote**: *"Reminder: We don't have sources"*
+- **This confirms**: The Google Fonts team acknowledges that no usable source files exist for the Elsie family. Hotfixes were performed directly on the binary font files.
+
+### PR #7160 (2024-01-16) -- More upstreams (e,f)
+- **Author**: Simon Cozens (simoncozens)
+- **Added**: The current `repository_url: "https://github.com/googlefonts/elsiefont (404)"` noting the URL was already dead.
+
+### PR #10266 (open) -- Fix broken repository_url in 6 METADATA.pb files
+- **Author**: felipesanches (AI-assisted)
+- **Proposes**: Removing the invalid URL entirely from the source block.
+- **Status**: Open, not yet merged.
+
+## Related Family
+- **Elsie Swash Caps** (`ofl/elsieswashcaps/`): Sibling family by the same designer. Uses `librefonts/elsieswashcaps` as upstream, which also has SFD-only sources.
+
+## Designer Information
+- **Alejandro Inler** (alejandroinler@gmail.com): No GitHub account found (HTTP 404 for `github.com/alejandroinler`).
+- **Ana Sanfelippo**: Co-developer credited in the description.
+- The copyright dates are 2010-2012, predating the Google Fonts onboarding.
+
+## Config.yaml Assessment
+- **No config.yaml** exists in `librefonts/elsie`.
+- **No config.yaml** exists in `ofl/elsie/` in google/fonts.
+- **Cannot create an override config.yaml**: The only source files are SFD (FontForge) and VFB (FontLab 5), neither of which is supported by gftools-builder. There are no `.glyphs`, `.ufo`, or `.designspace` files to reference.
+
+## Conclusions
+
+### Repository URL
+The correct upstream repository is **https://github.com/librefonts/elsie**. While this is a legacy archive (last updated 2014) and the sources are not gftools-builder compatible, it is the only repository containing actual source files for this font family. The `googlefonts/elsiefont` URL was always invalid, and `googlefonts/elsie` exists but is empty.
+
+### Commit Hash
+No specific onboarding commit can be identified in `librefonts/elsie`. The repo has only 12 commits (all from 2014), with the latest being `9734e9f` (2014-10-17, a Travis CI update). The font sources (SFD/VFB files) were all added in the initial commit `af81473` (2014-07-16) and never modified after that.
+
+The font binaries in google/fonts have been hotfixed multiple times (PR #884, PR #2754) directly without rebuilding from sources.
+
+### Status
+- **Repository URL**: `https://github.com/librefonts/elsie` (valid, contains SFD sources)
+- **Commit hash**: `af81473` (initial commit containing all source files; sources never changed after this)
+- **Config**: None (SFD-only sources, not gftools-builder compatible)
+- **Status**: `missing_config` -- SFD-only sources cannot be built with gftools-builder
+- **Confidence**: MEDIUM -- The librefonts/elsie repo contains legitimate SFD sources but was never the official upstream used for Google Fonts onboarding. The fonts were likely compiled from VFB/SFD sources offline by the designer and submitted as binaries. Subsequent hotfixes were done directly on binaries.
+
+## Recommended Actions
+1. **Update METADATA.pb**: Replace the invalid `"https://github.com/googlefonts/elsiefont (404)"` URL with `"https://github.com/librefonts/elsie"`.
+2. **Note in source block**: This is a SFD-only repo; no gftools-builder rebuild is possible without source format conversion.
+3. **PR #10266 update**: The currently open PR proposes removing the URL entirely. It could instead be updated to point to `librefonts/elsie` as the best available source repository.
