Register entities must check whether the beneficial ownership information they hold concerns persons or entities designated under targeted financial sanctions, immediately upon each designation and at regular intervals, and must flag in the register any legal entity or arrangement that is itself sanctioned, is controlled by a sanctioned person or entity, or has a sanctioned beneficial owner. The flag is visible to everyone with access and stays until the sanctions are lifted.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
