Each configuration has one train split. The dataset combines existing sources under a common schema with exact-pair deduplication, pinned provenance and evaluation-overlap filtering.
Curation and provenance
Rows preserve question and answer text, source repository/configuration/split/revision, original IDs, language, license, repository/path/URL, JSON metadata and a binary SHA-256 content_id. Repository and path coverage varies by source.
Exact duplicates are identified by question and answer hashes plus ordered field types, with line endings normalized. Multiple questions per code and multiple positive answers per question remain separate pairs. Filtering preserves retained field values.
Included sources declare MIT, Apache-2.0, CC BY 4.0 or CC BY-SA 4.0. Sources with unspecified, custom, noncommercial or no-derivatives terms are excluded. Rows with other or unrecognised license identifiers are omitted, including unknown original-code licenses in the Shuu collections. This filter excluded 7,639,316 pairs. The publication audit records counts and decisions.
Licensing and attribution
Upstream creators retain credit for the code, queries, annotations, translations and source datasets. ATTRIBUTIONS.md lists pinned sources; CITATIONS.md contains their citations. Source cards and available notices are preserved in upstream-cards/ and upstream-notices/.
LICENSES.md records source-specific terms. Original code may carry separate repository licenses. Required copyright notices, license texts and change disclosures must be retained; CC BY-SA material remains subject to applicable share-alike conditions. The collection does not relicense upstream material.
Evaluation overlap and limitations
Pairs were checked against 1,538 evaluation queries and 2,059 positive documents from takarajordan/code-search-eval-audited at revision 50b8424c85cf929d3075dbbaa2bc34b4cd8c589a. Exact matches and lexical shingle Jaccard ≥0.90 matches were excluded, checking both fields in either direction.
The overlap checks cover that evaluation companion only. Semantic near-duplicates and repository-level overlap may remain. Positive labels have not been independently verified for relevance or execution correctness.
Credential cleanup excluded 118 credential-bearing or dependent provenance records from the source build. Those checks covered two reported upstream keys.
Files and audit
files.json lists public shards, row counts, sizes and SHA-256 checksums. build/publication-audit.json records the pinned input and filtering policy.
