Step 3: Add QUIC Support to BaseAgent

File: /workspaces/agentic-qe-cf/src/agents/BaseAgent.ts

Add QUIC-related code to existing BaseAgent:

// Add to BaseAgentConfig
export interface BaseAgentConfig {
  // ... existing fields ...
  enableQuic?: boolean;
  quicConfig?: QUICConfig;
}

// Add to BaseAgent class
export abstract class BaseAgent extends EventEmitter {

        }
      }
    });
  }
}

Step 4: Testing QUIC Transport

File: /workspaces/agentic-qe-cf/tests/transport/QUICTransportManager.test.ts

import { QUICTransportManager } from '../../src/transport/QUICTransportManager';
import { SwarmMemoryManager } from '../../src/core/memory/SwarmMemoryManager';
import { AgentMessage } from '../../src/types';

describe('QUICTransportManager', () => {
  let memoryManager: SwarmMemoryManager;

  beforeEach(async () => {
    memoryManager = new SwarmMemoryManager(':memory:');
    await memoryManager.initialize();

    transport = new QUICTransportManager(
      {
        port: 4433,
        cert: './test/certs/test.crt',
        key: './test/certs/test.key'
      },
      memoryManager
    );
  });

  afterEach(async () => {
    await transport.shutdown();
    await memoryManager.close();
  });

  it('should initialize QUIC server', async () => {
    await transport.initialize();
    expect(transport['server']).toBeDefined();
  });

  it('should connect to peer', async () => {
    // Register peer in agent_registry
    await memoryManager.registerAgent({
      id: 'agent-1',
      type: 'test-generator',
      capabilities: [],
      status: 'active',
      performance: {
        quicEnabled: true,
        quicAddress: '127.0.0.1:4434'
      }
    });

    await transport.initialize();
    const connection = await transport.connectToPeer('agent-1');
    expect(connection).toBeDefined();
  });

  it('should send message via QUIC', async () => {
    // Setup peer
    await memoryManager.registerAgent({
      id: 'agent-1',
      type: 'test-generator',
      capabilities: [],
      status: 'active',
      performance: {
        quicEnabled: true,
        quicAddress: '127.0.0.1:4434'
      }
    });

    await transport.initialize();

    const message: AgentMessage = {
      id: 'msg-1',
      from: { id: 'agent-0', type: 'coordinator', created: new Date() },
      to: { id: 'agent-1', type: 'test-generator', created: new Date() },
      type: 'task-assignment',
      payload: { task: 'generate tests' },
      timestamp: new Date(),
      priority: 'medium'
    };

    await expect(transport.sendMessage('agent-1', message)).resolves.not.toThrow();

Testing Guidelines

QUIC Testing

# Run QUIC transport tests
npm test -- tests/transport/QUICTransportManager.test.ts

# Benchmark QUIC latency
npm run benchmark:quic

Neural Testing

# Run neural pattern matcher tests
npm test -- tests/neural/NeuralPatternMatcher.test.ts

# Train model
npm run neural:train

# Validate model accuracy
npm run neural:validate

Troubleshooting

QUIC Connection Fails

Problem: QUIC connection timeout

Solution:

1. Check firewall rules: sudo ufw allow 4433/udp
2. Verify certificates: openssl x509 -in ./certs/agent.crt -text
3. Check peer discovery: Agent must be in agent_registry with quicEnabled: true

Neural Training Fails

Problem: Insufficient patterns for training

Solution:

1. Ensure QEReasoningBank has 50+ patterns
2. Run pattern generation: npm run patterns:generate
3. Check pattern quality: npm run patterns:validate

Memory Issues

Problem: JavaScript heap out of memory

Solution:

export NODE_OPTIONS="--max-old-space-size=4096"
npm start

---

Next Steps

1. Review architecture: Read phase3-architecture.md
2. Study diagrams: Review phase3-diagrams.md
3. Implement QUIC: Follow Phase 3.1 steps above
4. Implement Neural: Follow Phase 3.2 steps above
5. Run tests: Validate both features work correctly
6. Deploy: Roll out to production with feature flags
