"""Provenance subsystem — normalisers, mapper, verifier.

Three pieces compose the reliability check:

* :mod:`ix.provenance.normalize` — pure text/number/date/IBAN normalisers
  used to compare OCR snippets to extracted values.
* :mod:`ix.provenance.mapper` — resolves LLM-emitted segment IDs to
  :class:`~ix.contracts.provenance.FieldProvenance` entries.
* :mod:`ix.provenance.verify` — per-field-type dispatcher that writes the
  ``provenance_verified`` / ``text_agreement`` flags.

Only :mod:`normalize` is exported from the package at this step; the mapper
and verifier land in task 1.8.
