# SWE-bench Style Coding Agent Dataset: GitHub Issues, Patches & Tests (Decontaminated)

*Release name: SWEGraph v2 — Free Sample*

A free, deterministic ~10% sample of **SWEGraph v2**: the complete SWE-bench family,
SWE-smith and BigCodeBench normalized into proof chains (`repo -> issue -> patch -> diff
hunks -> tests -> agent task -> eval task`) with identity/contamination groups and a
leakage-audited split. The full package is sold separately (see below).

* **License:** CC BY-NC 4.0 for the MatrixNorm normalization/packaging layer (see
  [Licensing](#licensing)).
* **Format:** gzipped **CSV** in `csv/` (all columns as text; list fields pipe-delimited) plus
  a **Parquet mirror** in `parquet/` with identical rows, used by `load_dataset` and the viewer.

```python
from datasets import load_dataset
tasks = load_dataset("williamTLmiller/matrixnorm-swegraph-v2-sample", "agent_tasks", split="train")
```

## How the sample was drawn

* **Unit = repository family** (a SWE-smith mirror belongs to its upstream's family).
  Keep a family iff the first byte of SHA-1(`"sample:" + family name`) is `< 26`
  (of 256).
  Families are kept whole, so contamination groups and partitions are never cut.
* **Same rule on every table**: tables with a `repo_id` keep the sampled families; group,
  quality, validity, proof, environment and membership rows are kept when they refer to a
  kept task or record. `split_manifests` is included in full.
* The `split` column is the full package's partition, unchanged. Because whole families are
  sampled, a sample may contain no validation or test family.
* Built 2026-10-23T22:50:54Z.

## The full dataset

The licensed package holds every table above in full, plus per-entity JSONL streams with the
complete nested fields (including each task's full PASS_TO_PASS regression list), provenance,
rights and leak-audit files. Perpetual, non-exclusive license for internal research,
training and benchmarking; models you train are yours to commercialize; no redistribution
of the dataset itself. **Contact:** energea@energeatech.com

## Sources

| Source | Rows used | License of the source release |
|---|---|---|
| SWE-bench (test, dev, train) | 2,294 + 225 + 19,008 | MIT |
| SWE-bench Verified / Lite / Multimodal | 500 / 323 / 612 (subsets and extensions of SWE-bench) | MIT |
| SWE-bench Multilingual | 300 | MIT |
| SWE-bench Pro V2 (`default`; `hard` recorded as membership) | 642 | MIT tooling; task content under upstream repo licenses |
| SWE-smith | 59,136 | MIT |
| BigCodeBench v0.1.4 | 1,140 | Apache-2.0 |

Task content (issue text, patches, tests) comes from public open-source repositories and
remains under each repository's own license; the exporter only ships verbatim code text where
`rights_manifest.csv` allows it.

## Licensing

* **This sample:** [CC BY-NC 4.0](LICENSE) — attribution, non-commercial — applies to the
  MatrixNorm normalization and packaging layer.
* **Underlying data:** the source releases keep their own licenses (copies included as
  `LICENSE-*-UNDERLYING-*.txt`); repository content stays under each repository's license.
  See [NOTICE](NOTICE).
* **Commercial use** of the normalized package requires the paid license.

## Limitations

* Task validity gates are `not_run` until real execution evidence exists.
* Issue and PR text is reproduced from public GitHub as published in the source releases.
* Not produced, reviewed or endorsed by the authors of any source dataset.
