    // Execute authentication
    const results = await Promise.all(
      factors.map(factor => this.executeFactor(userId, factor))
    );
    
    return results.every(r => r.success);
  }
}

        )
        
        # Risk scoring
        results['risk_score'] = self.ml_model.calculate_risk({
            'customer': customer_data,
            'verification_results': results
        })
        
        # Decision
        if results['risk_score'] > 70:
            return {'status': 'rejected', 'reason': 'High risk'}
        elif results['risk_score'] > 40:
            return {'status': 'manual_review', 'results': results}
