    Returns:
        Result object with processed data or error details
    
    Raises:
        ValidationError: If validation fails and validate=True
    """
    try:
        if validate:
            _validate_input(data)
        # Processing logic...
    except ValidationError as e:
        logger.error(f"Validation failed: {e}")
