## Known constraints

<AccordionGroup>
  <Accordion title="Lobbying lobbyist name coverage">
    Lobbyist names are sometimes incomplete in communication records. NorthAxium Data falls back to the matching registration row when possible, which raises effective name coverage to roughly 90%. The MCP tool reflects the same fallback.
