License policy

Only files whose recorded license is in the allowed set were retained: 0bsd, apache-2.0, bsd, bsd-2-clause, bsd-3-clause, cc0-1.0, isc, mit, mitre, ms-pl, unlicense.

Excluded: GPL, AGPL, LGPL, MPL, unknown, no-license, proprietary.

Filtering

Kept C# (.cs/.csx) and .NET build/config files (.csproj,.sln,.props, .targets,.editorconfig,.config, global.json, nuget.config, appsettings.json, ...).
Removed: binaries, generated code (<auto-generated>, .designer.cs, .g.cs, do not edit), minified (median/max line length thresholds), vendored/large data blobs, secrets.
Size window 40�300000 chars.
Exact dedup by SHA-256 of normalized content; near-dedup by MinHash LSH (128 permutations, 16 bands, Jaccard >= 0.8).

Splits (repository-level)

A repository's files always map to one split via a deterministic hash of repo_name, so no repository appears in more than one split. { "test": { "files": 9711, "tokens": 9151159, "repos": 1061 }, "train": { "files": 662253, "tokens": 676849804, "repos": 66796 }, "validation": { "files": 9462, "tokens": 9287205, "repos": 1012 } }

Secret scanning

{ "files_quarantined": 949, "by_reason": { "secret": 949 }, "unresolved_findings_in_corpus": 0, "note": "Every retained file passed the secret scanner; matches were excluded (quarantined), so zero unresolved findings remain." }

Schema

text, repo_name, path, source_url, commit_or_blob_id, license,
source_dataset, content_sha256, quality_score, category_slice, token_count,
is_synthetic, collected_at

Provenance

source_dataset: codeparrot/github-code.
source_url: HEAD-based GitHub blob URL (https://github.com/<repo>/blob/HEAD/<path>).
commit_or_blob_id: ghcode:<shard>:<sha12> retrieval id.
content_sha256: SHA-256 of normalized content.
Limitation: codeparrot/github-code does NOT carry an upstream per-file commit/blob SHA; the recorded commit_or_blob_id is the dataset-internal retrieval id, not a GitHub commit hash. Enriching with exact upstream commits requires per-repo resolution (deferred).

Storage

Zstandard (level 9) Parquet; data shards ~300 MB compressed. Compressed total: 1.19 GB; uncompressed: 7.10 GB. Verified shards: 180/184.

Reproducibility

Pipeline: src/pipeline.py (download->filter->dedup->classify->tokenize->shard->upload), src/finalize_splits_reports.py (splits + reports). Deterministic split + MinHash seeds.
