 * Coverage target: 80%+
 */

import { QUICTransportWrapper, AgentDBIntegration } from '../../../src/core/memory/AgentDBIntegration';

describe('AgentDBIntegration', () => {
  describe('QUICTransportWrapper', () => {
    describe('Initialization', () => {
      it('should initialize transport with valid config', () => {
        // TODO: Implement
      });
    });
  });
});
EOF

# 3. Run initial test (should have 0 tests)
npm test tests/unit/memory/AgentDBIntegration.test.ts
