Architecture:

interface RegistryService {
  // Registration
  register(agentCard: AgentCard): Promise<Agent>;
  update(agentId: string, updates: Partial<AgentCard>): Promise<Agent>;
  delete(agentId: string): Promise<void>;
  
  // Discovery
  search(query: SearchQuery): Promise<Agent[]>;
  getAgent(agentId: string): Promise<Agent>;
  listAgents(filters: Filters): Promise<Agent[]>;
  
  // Verification
  verifyDomain(agentId: string, method: 'dns' | 'file'): Promise<boolean>;
  signAgentCard(agentId: string, privateKey: string): Promise<Signature>;
  
  // Lifecycle
  updateStatus(agentId: string, status: AgentStatus): Promise<void>;
  deprecateVersion(agentId: string, version: string): Promise<void>;
}

2. Orchestration Layer

Smart routing, load balancing, and workflow management for reliable multi-agent systems.

Task Router
Load Balancer
Workflow Engine

Intelligent Task Routing

class TaskRouter {
  route(task: Task, constraints: Constraints): Agent {
    // Find compatible agents
    const candidates = registry.search({
      capabilities: task.requiredCapabilities,
      available: true
    });
    
    // Apply routing strategy
    switch (constraints.optimize) {
      case 'cost':
        return selectLowestCost(candidates);
      case 'latency':
        return selectFastest(candidates);
      case 'quality':
        return selectBestRated(candidates);
      default:
        return loadBalancer.select(candidates);
    }
  }
}

Distribute Load Across Instances

class LoadBalancer {
  strategy: 'round-robin' | 'least-connections' | 'weighted';
  healthCheck: HealthChecker;
  
  select(instances: AgentInstance[]): AgentInstance {
    // Filter healthy instances
    const healthy = instances.filter(i => 
      this.healthCheck.isHealthy(i)
    );
    
    // Apply strategy
    return this.applyStrategy(healthy);
  }
  
  applyStrategy(instances: AgentInstance[]): AgentInstance {
    switch (this.strategy) {
      case 'round-robin':
        return this.roundRobin(instances);
      case 'least-connections':
        return this.leastConnections(instances);
      case 'weighted':
        return this.weighted(instances);
    }
  }
}

Execute Multi-Step Workflows

class WorkflowEngine {
  async execute(workflow: Workflow): Promise<WorkflowResult> {
    const context = new ExecutionContext();
    
    // Build DAG from tasks
    const dag = this.buildDAG(workflow.tasks);
    
    // Execute in topological order
    for (const level of dag.levels) {
      // Parallel execution within level
      await Promise.all(
        level.map(task => this.executeTask(task, context))
      );
    }
    
    return context.getResult();
  }
  
  async executeTask(task: Task, context: Context): Promise<void> {
    // Route to appropriate agent
    const agent = this.router.route(task, workflow.constraints);
    
    // Execute with retry logic
    const result = await this.retryExecutor.execute(
      () => agent.execute(task.input),
      { maxRetries: 3, backoff: 'exponential' }
    );
    
    // Store result in context
    context.setResult(task.id, result);
  }
}

Features:

Cost-aware routing (optimize for performance or budget)
Retries and circuit breakers
Backpressure handling
Task lifecycle management
Parallel execution
Dependency resolution

3. Security & Authentication

Enterprise-grade security with multiple authentication schemes.

Authentication Methods

Supported Auth Schemes:

Bearer Token: Simple token-based authentication
API Key: Header or query parameter authentication
OAuth 2.0: Authorization Code and Client Credentials flows
Mutual TLS: Certificate-based authentication
Custom: Plugin your own auth mechanism

interface AuthProvider {
  authenticate(request: Request): Promise<Principal>;
  authorize(principal: Principal, resource: Resource): Promise<boolean>;
}

class BearerTokenAuth implements AuthProvider {
  async authenticate(request: Request): Promise<Principal> {
    const token = extractBearerToken(request);
    const claims = await this.validateToken(token);
    return new Principal(claims);
  }
}

Authorization & Access Control

Role-Based Access Control (RBAC)

interface AccessControl {
  roles: Role[];
  permissions: Permission[];
  policies: Policy[];
  
  hasPermission(
    principal: Principal,
    action: Action,
    resource: Resource
  ): boolean;
}

// Example: Check agent execution permission
if (accessControl.hasPermission(user, 'execute', agent)) {
  await agent.execute(task);
}

Rate Limiting

Protect Against Abuse

class RateLimiter {
  limits: Map<string, RateLimit>;
  
  async checkLimit(
    key: string,
    limit: RateLimit
  ): Promise<boolean> {
    const current = await this.getCount(key);
    
    if (current >= limit.max) {
      throw new RateLimitExceeded(limit);
    }
    
    await this.increment(key, limit.window);
    return true;
  }
}

// Example: 100 requests per hour per user
rateLimiter.checkLimit(
  `user:${userId}`,
  { max: 100, window: 3600 }
);

Audit Logging

Compliance & Security Monitoring

interface AuditLog {
  timestamp: Date;
  principal: Principal;
  action: string;
  resource: string;
  result: 'success' | 'failure';
  metadata: Record<string, any>;
}

class AuditLogger {
  log(event: AuditLog): void {
    // Store in compliance-ready format
    this.storage.append({
      ...event,
      retention: '7years',
      immutable: true
    });
  }
}

4. Observability Suite

  tracer: Tracer;
  metrics: MetricsCollector;
  logger: Logger;
  
  // Instrument agent execution
  async instrumentExecution<T>(
    operation: string,
    fn: () => Promise<T>
  ): Promise<T> {
    const span = this.tracer.startSpan(operation);
    const timer = this.metrics.startTimer(operation);
    
    try {
      const result = await fn();
      
      span.setStatus({ code: SpanStatusCode.OK });
      this.metrics.increment(`${operation}.success`);
      
      return result;
    } catch (error) {
      span.setStatus({
        code: SpanStatusCode.ERROR,
        message: error.message
      });
      
      this.metrics.increment(`${operation}.error`);
      this.logger.error(operation, { error });
      
      throw error;
    } finally {
      timer.end();
      span.end();
    }
  }
}

5. AP2 Integration

Payment processing and deployment infrastructure.

class PaymentService {
  processor: PaymentProcessor;
  consentManager: ConsentManager;
  auditLog: AuditLogger;
  
  async processPayment(
    intent: PaymentIntent,
    userId: string
  ): Promise<PaymentResult> {
    // Request user consent
    const consent = await this.consentManager.request({
      userId,
      amount: intent.amount,
      description: intent.description
    });
    
    // Wait for approval
    const approved = await consent.waitForApproval(timeout: 300);
    
    if (!approved) {
      throw new ConsentDenied();
    }
    
    // Process payment
    const result = await this.processor.charge({
      amount: intent.amount,
      currency: intent.currency,
      paymentMethod: intent.paymentMethod
    });
    
    // Audit trail
    this.auditLog.log({
      action: 'payment.processed',
      userId,
      consentId: consent.id,
      transactionId: result.id,
      amount: intent.amount
    });
    
    return result;
  }
}

Scalability & Reliability

Horizontal Scaling

All components are designed to scale horizontally:

# Kubernetes Deployment Example
apiVersion: apps/v1
kind: Deployment
metadata:
  name: intra-orchestrator
spec:
  replicas: 10
  selector:
    matchLabels:
      app: orchestrator
  template:
    spec:
      containers:
      - name: orchestrator
        image: intra/orchestrator:latest
        resources:
          requests:
            cpu: 500m
            memory: 1Gi
          limits:
            cpu: 2000m
            memory: 4Gi

High Availability

Multi-region deployment: Deploy across AWS, GCP, Azure
Active-active: All regions serve traffic
Automatic failover: Health checks and circuit breakers
Data replication: Consistent cross-region data

Disaster Recovery

Backup & Restore: Automated daily backups
Point-in-time Recovery: Restore to any point in last 30 days
RTO: < 1 hour
RPO: < 15 minutes
