# Declared dataset split overlap audit

Build-time release reference. Runtime readiness, deployment, payment settlement and external indexing are not evaluated here. Prices are proposed; this file cannot authorize execution or payment.

Find exact item ID, group ID and supplied SHA-256 fingerprint overlaps across caller-declared dataset partitions. Reports missing identity coverage and capped locations; no data fetching, hash verification, near-duplicate detection or proof of leakage-free evaluation.

Release: 0.29.0. Built: 2026-10-06T15:38:00Z.

## Choose for
- Find exact train validation test overlap from supplied IDs and group keys
- Audit group leakage candidates before an agent evaluation run

## Outside this profile
- Extracting facts or judging truth, semantic correctness, evidence authenticity, causal effects, or production readiness
- Fetching data, executing models or user code, changing datasets, authorizing actions, or contacting live services
- Inferring population quality, statistical significance, uncertainty intervals, or generalization from a supplied sample

Proposed nominal USD 0.005 per successful call; payer fees excluded. No verified runtime availability.
