# Document Chunk Integrity 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.

Audit supplied retrieval/document chunks against their exact source spans and compute verified coverage, uncovered ranges, overlap depth and policy findings. Invalid chunks never contribute coverage. Checks identity and coverage only, not retrieval quality or semantic relevance.

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

## Choose for
- Verify exported RAG chunks reconstruct and cover their source document
- Find stale chunk text, gaps or forbidden overlaps before indexing

## Outside this profile
- Semantic chunk quality, source authenticity, OCR correction or embedding validation
- Comparing independent ground-truth annotation datasets

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