Manual report review
The QA workspace lets a reviewer complete a checklist, approve or reject a report, and record a reason. The operation enters the audit log.
Extractor exceptions are not currently routed automatically to a dedicated expert queue. A person must deliberately open the report or answer and review it.
Methodology governance

No change ships because it improves the numbers — the criterion is measurement rigour. Responsibility for the methodology is assigned to named people, not to "the system".
