+# Investigation Report: Linefont
+
+**Model**: Claude Opus 4.6
+
+## Summary
+
+Linefont is a display/symbols variable font by Dmitry Ivanov (Dmitry Iv.) that encodes sparkline data as text. It was onboarded to Google Fonts on 2023-09-27 by Rosalie Wagner via gftools-packager. The source block in METADATA.pb was substantially complete, with repository URL, commit hash, files mapping, branch, and config_yaml all present. However, the commit hash was incorrect: it referenced the latest upstream commit (`9edec1a`, "Create tea.yaml", 2025-01-18) rather than the original onboarding commit (`347effe`, "Make rlig feature section", 2023-09-27).

+
+## Commit Hash Analysis
+
+### Original Onboarding Commit
+
+The gftools-packager commit `dfef2e4b2` in google/fonts (2023-09-27) explicitly referenced upstream commit `347effeda6955b1aa7febc34e17dcce3e04f5e15`:
+
+> Linefont Version 3.002;gftools[0.9.33] taken from the upstream repo https://github.com/dy/linefont at commit https://github.com/dy/linefont/commit/347effeda6955b1aa7febc34e17dcce3e04f5e15.
+
+This commit ("Make rlig feature section", authored 2023-09-27T11:40:23Z) was the HEAD of the upstream repo at onboarding time. The PR #6799 was merged on 2023-10-11.
+
+### How the Hash Changed
+
+1. **Original state** (commit `dfef2e4b2`, 2023-09-27): Source block had `commit: "347effeda6955b1aa7febc34e17dcce3e04f5e15"`.
+2. **upstream.yaml merge** (commit `66f91f10f`, 2024-04-03): Added `files`, `branch`, and `minisite_url` to METADATA.pb, but kept the original commit hash `347effe`.
+3. **Batch 2/4 fontc_crater import** (commit `4ad8ac680`, 2025-03-31): Changed the commit hash from `347effe` to `9edec1a` and added `config_yaml: "sources/config.yaml"`. This update came from the fontc_crater targets.json file, which tracked the latest upstream HEAD rather than the original onboarding commit.
+
+### Commits Between `347effe` and `9edec1a`
+
+A GitHub API comparison showed only 4 commits were added between these two hashes, changing only `readme.md` (modified) and `tea.yaml` (added). **No font source files were changed.** The font binary in google/fonts is byte-identical to the one in the upstream repo at `9edec1a` (SHA-256: `94cab92c51d91e7cac90f03144fa527a9fc6d1712bbbe09ab04c28cdf922026e`).
+
+### Correct Commit Hash
+
+The correct onboarding commit is **`347effeda6955b1aa7febc34e17dcce3e04f5e15`** ("Make rlig feature section", 2023-09-27). While `9edec1a` produces the same font sources, the policy is to reference the exact commit used during onboarding. The current hash `9edec1a` ("Create tea.yaml", 2025-01-18) postdates the onboarding by over a year and was introduced erroneously by the batch fontc_crater import.
+
+## Config.yaml
+
+The upstream repo has a `config.yaml` at `sources/config.yaml` that was present at the onboarding commit `347effe`. This is a valid gftools-builder configuration:
+
+```yaml
+buildVariable: true
+buildStatic: true
+sources:
+ - Linefont.designspace
+familyName: Linefont
+axisOrder:
+ - wdth
+ - wght
+stat:
+ - name: Width
+ tag: wdth
+ values:
+ - name: SuperCondensed
+ value: 25
+ # ... (full STAT table definitions)
+ - name: Weight
+ tag: wght
+ values:
+ - name: Thin
+ value: 100
+ # ... (full STAT table definitions)
+```
+
+The `config_yaml: "sources/config.yaml"` field in METADATA.pb is correct. No override config.yaml exists in the google/fonts family directory.
+
+## Upstream Repository Notes
+
+- The local clone at `upstream_repos/fontc_crater_cache/dy/linefont` is a shallow clone with only 1 commit (`9edec1a`). The full history (30+ commits) is available on GitHub.
+- The repo contains two sets of sources: `sources/` (with the designspace and 12 UFO masters) and `_sources/` (an older version with a single master UFO). The config at `sources/config.yaml` correctly references `Linefont.designspace` relative to the `sources/` directory.
+- Rosalie Wagner contributed to the upstream repo via PRs #13 and #14, adding supercondensed width and fixing design issues before the onboarding commit.

+## Recommended Fix
+
+The commit hash in METADATA.pb should be corrected from `9edec1a1f780db52db0297bab464451f3dbd4d5a` back to `347effeda6955b1aa7febc34e17dcce3e04f5e15` (the original onboarding commit). All other fields are correct.
+
+## Status
+
+- **Repository URL**: Correct
+- **Commit hash**: Incorrect (needs correction from `9edec1a` to `347effe`)
+- **Config**: `sources/config.yaml` -- correct, present in upstream repo
+- **Overall status**: needs_correction
+- **Confidence**: HIGH
