Clean math SFT problem pool
Inference-free preparation of MATH training, NuminaMath-1.5, and original s1K.
Only questions, extracted gold answers, and provenance are retained; no generated traces.
The metadata column contains lossless JSON text for heterogeneous source metadata.
Source licenses remain applicable; see provenance.json for upstream metadata and revisions.
The repository's unchanged AIME 2024/2025/2026, AMC 2023, MATH-500 evaluation
references and its content-checked DAPO RL set are excluded using distinct n-gram coverage.
summary.json contains stage counts; removed.jsonl records every removal;
conflicts.jsonl quarantines conflicting duplicate clusters; merged_clusters.jsonl
records merges. The two *_near_misses.jsonl files list manual-review candidates
in descending coverage order. Exact number-swapped templates can appear below the
usual near-miss band and are explicitly marked. Eval near misses are recorded at
the eval stage, so a candidate can subsequently be removed for RL overlap.
Filtering uses conservative rules, not a semantic classifier; inspect the audit logs. Symbolic parsing does not establish that an upstream gold answer is correct. Lexical normalization removes punctuation, and is not symbolic canonicalization. Conflicting near-duplicate clusters are dropped in full as a conservative policy.
See provenance.json for the complete config, pinned inputs, code commit and
bundled-file hashes. This artifact performs no model inference or training.
