Core Components​

API Gateway Layer​

Compliance Engine Architecture​

interface ComplianceEngineConfig {

    }

    // 2. Determine applicable frameworks
    const applicableFrameworks = this.getApplicableFrameworks(requirement);

    // 3. Process with each framework

Data Flow Architecture​

Request Processing Flow​

    ];
  }

  async processRequest(request: IncomingRequest): Promise<ProcessedResponse> {
    let context = new ProcessingContext(request);

    for (const stage of this.pipeline) {
      try {

    this.deadLetterQueue = new DeadLetterQueue();
  }

  async emit(eventType: string, payload: any): Promise<void> {
    const event: Event = {
      id: generateUUID(),
      type: eventType,
      payload,
      timestamp: Date.now(),
      source: 'compliance-engine',
    };

    // Store event for persistence
    if (this.config.persistence) {
      await this.eventStore.store(event);
    }

    // Get subscribers for this event type
    const handlers = this.subscribers.get(eventType) || [];

    // Process handlers in parallel

    await Promise.allSettled(handlerPromises);
  }

  private async processHandler(

        await this.retryManager.scheduleRetry(handler, event);
      } else {
        await this.deadLetterQueue.add(event, error);
      }
    }
  }

  subscribe(eventType: string, handler: EventHandler): void {
    if (!this.subscribers.has(eventType)) {
      this.subscribers.set(eventType, []);
    }
    this.subscribers.get(eventType)!.push(handler);
  }
}

// Event handlers for different services
class ComplianceScoreHandler implements EventHandler {
  async handle(event: Event): Promise<void> {
    if (event.type === 'requirement:updated') {
      await this.recalculateComplianceScore(event.payload.requirementId);
    }
  }

  private async recalculateComplianceScore(

      requirementId,
      newScore,
      timestamp: Date.now(),
    });
  }
}

Security Architecture​

    }
  }

  async authorize(

Scalability and Performance​

Horizontal Scaling Architecture​

class ScalingManager {
  private loadBalancer: LoadBalancer;

Monitoring and Observability​

Distributed Tracing​

class TracingManager {
