## Evidence gaps

- Independent verification of qualifications and professional memberships remains incomplete.

- Person-specific court, regulator, fraud and prior-employer searches are not exhaustive; open-web research is not a clearance.

- Original queries were limited and sometimes combined people or topics; dedicated person-by-person and prior-employer records searches, including adverse topics and outcomes, were not completed.
