Evidence gaps

• Independent credentials and professional membership were not confirmed with institutions.

• Prior-employer dates, outcomes and personal contributions require broader independent corroboration.

• Court, regulator and local-language records across relevant jurisdictions were not comprehensively reviewed; this is a limited public-source screen.

• The final Abujar fatality investigation and any Ivorian regulatory response were not found.

• The Robex circular describes CEO appointment from 17 June 2024 and board service from 27 June 2024; those are separate roles.

• Toubani directorship continuation at the cutoff and any conflict-management arrangements were not independently confirmed.

• The review reused broad name-and-employer searches across topics; dedicated searches of each topic for each former employer and every jurisdiction were not completed.
