+# Dataset Card � csharp-dotnet-cpt-v0
+
+## Intended use
+Continued pretraining of Qwen2.5-Coder-1.5B on C#/.NET code. Named slices allow
+training separate LoRA adapters per domain.
+
+## Source
+- **Primary:** `codeparrot/github-code` (public Hugging Face parquet dataset; per-file
+  `license` label derived from each repository's LICENSE file via a go-license classifier).
+- 179 of 1126 source shards processed.
+- **Not used (gated, access not granted on this account):** `bigcode/the-stack`,
+  `bigcode/the-stack-v2-train`, `bigcode/the-stack-smol`, `bigcode/the-stack-dedup`.
+
+## 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.
+
+### Tokens per license
+- `mit`: 460,905 files, 430,391,064 tokens
+- `apache-2.0`: 167,699 files, 204,609,979 tokens

+- `cc0-1.0`: 1,881 files, 1,586,022 tokens
+- `isc`: 822 files, 437,927 tokens
+
+## 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.

+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.
