├── DurableHandleV2Request.java      - Durable handle v2 with timeout
└── HandleReconnector.java           - Automatic handle reconnection
```

#### 2.2 Implementation Tasks
- [ ] Implement persistent/durable handle contexts
- [ ] Add handle GUID generation and tracking
- [ ] Implement handle state serialization
- [ ] Create reconnection logic with handle replay
- [ ] Add timeout management for durable handles
