Counts

• Source (claude_reviewed_v2 train, READ-ONLY): 32,100 rows
• Published subset: 15,000 rows
• Labels: 697 (ATT&CK Enterprise v19.2)
• Distinct CVE ids in subset: 15,337
• Multi-record rows (cve_id joined with '|'): 166
• Sampling: uniform random without replacement, seed 42, indices ascending

Label Coverage

Full-train support from metadata.train_label_counts (asserted equal to the recount); subset support recomputed on the published rows.

Risk Feeds

• EPSS: 2,783/15,000 rows carry a score (18.6%); null for the rest (honest coverage, not imputed). Capture window re-read from the cache timestamps of the matched entries: 2026-09-29 to 2026-09-30.
• KEV: snapshot fetched_at 2026-10-16T11:33:28+00:00 (source https://www.cisa.gov/sites/default/files/feeds/known_exploited_vulnerabilities.json, 1,746 ids); 116/15,000 rows flagged.

Reproducibility

• Seed: 42 - random.Random(seed).sample(range(32100), 15000), sorted ascending
• Interpreter: CPython 3.11.9 (Mersenne Twister)
• Builder: scripts/build_hf_cve2attack_15k.py
• sha256 data/train.jsonl: 9a4168e61ea6cc7820707e7744bf2f2fb843778074e562a2f337f92d4683dc56
• sha256 data/train-00000-of-00001.parquet: f061e64c6e697d9f3c2cf7fc72e7388966a27c330a9f1a9fdd492b086ea28340
• Join: split_manifest['train'][i] is index-aligned with train.jsonl row i (producer contract in scripts/build_claude_reviewed_v2.py); cve_id read from the manifest group records; the v1-inherited description_hash is NEVER used for the join (77/32100 raw matches to sha256 of the v2 text).
• The KEV snapshot is reused across runs (--refresh-kev re-fetches and changes only KEV-derived dates).
