+# Commit Messages from High-Quality Repositories
+
+292,269 cleaned git commit messages scraped from the full histories of 15 well-regarded open-source
+projects, balanced across two styles: **normal** (196,372) and
+**conventional commits** (95,897).
+
+## Dataset Summary
+
+- Each record contains the commit `subject`, `body`, plus metadata: `repo`, `sha`, `date`,
+  `author`, and labels: `style` (normal/conventional), `type` (fix, feat, docs, ...),
+  `scope`, `breaking`.
+- Heavy cleaning: GitHub squash suffixes `(#123)` stripped, bot/automated commits removed,
+  canned boilerplate removed, exact duplicates removed, git trailers (Signed-off-by etc.)
+  stripped from bodies, junk subjects ("wip", "update", ...) removed.
+- **Temporal split**: train is the oldest ~98% of commits, validation the next ~1%, test the
+  newest ~1%. No train/eval temporal leakage: every eval commit is newer than every train commit.
+
+## Supported Tasks
+
+- `text-generation`: commit message generation, style modeling, conventional-commit
+  classification, software-engineering NLP.
+
+## Usage
+
+```python
+from datasets import load_dataset
+
+ds = load_dataset("USERNAME/REPO", "default")          # full metadata records
+view = load_dataset("USERNAME/REPO", "training_view")  # prompt/completion pairs (body -> subject)
+```
+
+`training_view` maps a change description (the commit body) to the commit subject line and is
+formatted for fine-tuning tools such as Unsloth, with explicit `prompt` and `completion` columns.

+## Upstream Licenses
+
+Commit messages are inherited from their source projects. Repositories under copyleft or
+source-available licenses (git: GPL-2.0; redis: BSD-3 / RSALv2 / SSPLv1) were **excluded**
+as a precaution: software licenses technically cover the licensed program rather than VCS
+metadata, but commit messages are therefore not openly licensed either, and longer commit
+bodies can constitute original expression of their authors. Only permissively-licensed
+projects are included:
+
+| Repository | License |
+|---|---|

+| vuejs/core | MIT |
+| vitejs/vite | MIT |
+| babel/babel | MIT |
+| eslint/eslint | MIT |
+| ant-design/ant-design | MIT |

+## Cleaning Statistics
+
+| Filter | Records dropped |
+|---|---|
+| duplicate | 77,038 |
+| bad_subject | 16,190 |
+| bot_or_automated | 26,432 |
+| license_excluded | 83,369 |
+| canned_message | 9,943 |
+
+## Splits
+
+| Split | Records | Date range |
+|---|---|---|
+| train | 286,425 | 1996-07-09 → 2026-07-14 |
+| validation | 2,922 | 2026-07-14 → 2026-08-20 |
+| test | 2,922 | 2026-08-20 → 2026-09-23 |
+
+## Privacy
+
+- No author names or email addresses are included. Records are identified only by content
+  `sha` + repository, which preserves verifiable provenance without identifying individuals.
+- Note: commit bodies may reference contributor names in prose (e.g. credit lines), as these
+  are part of the historical commit text itself.
+
+## Limitations
+
+- English-dominant; commit messages from a single ecosystem of C/C++ and JavaScript/TypeScript projects.
+- No diffs attached: the dataset describes *what was written*, not the code change itself.
+- Bodies are truncated at 2,000 characters.
+- Human authors made the source commits; quality varies by repository and era.
+
+## Reproduction
+
+Built with a two-stage pipeline (blobless `git clone --filter=blob:none`, then
+`git log` export and rule-based cleaning). See `stats.json` for exact counts.
