Evidence gaps

• Full former-employer outcomes and precise tenure were not independently established.

• Independent verification of education, professional memberships and credentials is incomplete.

• Court, regulator and adverse-media searches are a limited public-source screen and do not establish absence of other matters.

• One broad combined named-person search was reused for multiple topic logs; separate comprehensive career, education, success, failure, fraud, safety, environment, legal and governance searches were not performed.
