Researched profiles for individuals named by full name (jane-doe.md, john-smith.md). Each profile contains: current role and company, professional background, social links, recent public activity, and user's relationship/context (how they know them, meeting notes). Create when user researches someone; update when preparing for meetings or when new information surfaces. Include research date for freshness. Check before meetings to refresh context. Don't store sensitive personal data—focus on professional, publicly available information. Cross-reference with ui:research.exa.companies for employer details.
