+# Della Respira -- Source Investigation
-## Summary
+**Model**: Claude Opus 4.6
+**Date**: 2026-03-03
-Della Respira is a serif display typeface designed by Nathan Willis, a revival of the Della Robbia typeface by American Type Founders (ATF). The original source was hosted on Launchpad using Bazaar version control, not GitHub. A librefonts mirror exists on GitHub but contains only TTX-decomposed files, not real font sources.
+## Source Repository
-## Key Findings
+**Repository**: [googlefontdirectory-hg](https://code.google.com/archive/p/googlefontdirectory/) (Mercurial monorepo)
+**Commit**: `52f780bc9d197280a9f430574e179a5f233c56b6`
+**Source path**: `dellarespira/src/`
-- **Designer**: Nathan Willis
-- **Date added to Google Fonts**: 2012-04-04
-- **Original source**: Launchpad (https://launchpad.net/revivalism-fonts/) using Bazaar VCS
-- **GitHub mirror**: https://github.com/librefonts/dellarespira (TTX-only, not buildable)
-- **Source formats available**: TTX decomposed files only (in librefonts mirror)
-- **config.yaml**: None (not applicable - no gftools-buildable sources)
-- **Override config.yaml**: None in google/fonts

-## Repository Analysis
+| File | Format | Buildable |
+|------|--------|-----------|
+| `METADATA_comments.txt` | Metadata | N/A |
-The librefonts/dellarespira GitHub repo was created by Mikhail Kashkin on 2014-07-16 as a mirror of the font data. It contains only TTX-decomposed font table files (the binary .ttf decompiled into XML), not actual editable font sources (.glyphs, .ufo, .sfd, etc.). The repo has 11 commits, all related to CI/Travis setup and TTX file organization.
+The `src/` directory contains only `METADATA_comments.txt` -- no original design sources. No `.glyphs`, `.ufo`, `.designspace`, `.sfd`, or `.vfb` files are present.
-The actual font source was maintained on Launchpad at `lp:revivalism-fonts` using Bazaar (bzr) version control. The Launchpad project page is still accessible.

+
+## Original Source
+
+The actual font source was maintained on Launchpad at `lp:revivalism-fonts` (https://launchpad.net/revivalism-fonts/) using Bazaar (bzr) version control. The Launchpad project page is still accessible. Bazaar VCS is not compatible with the Google Fonts toolchain.
-The font binary has not been updated since the initial commit (90abd17b4) of the google/fonts repository. No gftools-packager updates or font refreshes have occurred.
+## librefonts Mirror
-## Status
+A mirror exists at `https://github.com/librefonts/dellarespira` (created 2014-07-16 by Mikhail Kashkin). It contains only TTX-decomposed font table files (the binary .ttf decompiled into XML), not actual editable font sources. The repo has 11 commits, all related to CI/Travis setup and TTX file organization.
+
+## google/fonts History
-- **repository_url**: The librefonts mirror exists but has no buildable sources. The actual source was on Launchpad.
-- **commit**: N/A (no useful commit to reference in the TTX-only mirror)
-- **config_yaml**: N/A (no gftools-buildable sources exist)
-- **Overall**: no_upstream_repo - The only GitHub repo is a TTX mirror with no real font sources. The original Launchpad/Bazaar source is the true upstream but is not a GitHub repository.
+The font binary has not been updated since the initial commit (`90abd17b4`) of the google/fonts repository on 2015-03-07. No gftools-packager updates or font refreshes have occurred.
-## Recommendation
+## Build Configuration
-Status should remain `no_upstream_repo`. The librefonts mirror contains only TTX decomposed files and is not suitable as a build source. The original source on Launchpad uses Bazaar VCS which is not compatible with the Google Fonts toolchain.
+- **No config.yaml** exists in any known repository
+- **No override config.yaml** exists in the google/fonts family directory
+- No buildable design sources are available in googlefontdirectory-hg or the librefonts mirror
+- The original Launchpad/Bazaar source is the true upstream but uses a VCS not compatible with the Google Fonts toolchain
+- A config.yaml cannot be created for this family
