"""Stage 2 decontamination (``docs/02_DATA_PIPELINE.md`` §5, ``docs/07`` §5).

Fingerprints every normalized item (exact, pHash, OCR/question MinHash) into a
SQLite index, then matches train candidates against the evaluation index to
auto-reject exact contamination and near-duplicates, producing the train
allowlist and an immutable rejection report.

Public API:

- :func:`fingerprints.fingerprint_row` — one item's fingerprints
- :func:`index.write_fingerprints` / :func:`index.load_all` — the SQLite index
- :func:`match.decontaminate` / :func:`match.decontaminate_dbs` — classification,
  allowlist, and automatic-rejection report
