WHY IT NEEDS A POLICY

Why vivado_register_board needs a policy

The tool registers a board definition, which modifies the system's board configuration state. However, the description explicitly states it 'does not overwrite built-in boards,' which limits destructive impact. This is a reversible configuration change (Write) rather than Execute (which would run arbitrary code) or Destructive (which cannot be undone).

From the tool's definition Tool name 'vivado_register_board' and description 'Validate and return a board registration payload' indicates creation or registration of new board configurations in the Vivado system.
