- low: minor signals only
- medium: possible matches requiring review
- high: probable matches in sanctions or offshore leaks
- critical: high-confidence sanctions match

Examples:
screen_entity(name="Gazprom")
screen_entity(name="Kim Jong Un", entity_type="individual")
screen_entity(name="Evrofinance Mosnarbank", country="Russia")
