   ```bash
   npm test -- tests/unit/routing/
   npm test -- tests/unit/mcp/
   npm test -- tests/integration/phase1/
   npm test -- tests/performance/phase1-perf.test.ts
   ```

3. **Day 2** - Performance Benchmarks (4 hours)

### Best Practices Applied
- ✅ Feature flags for safe rollout
- ✅ Backward compatibility guarantee
- ✅ Comprehensive documentation
- ✅ Modular architecture (routing, streaming as separate modules)
- ✅ Type safety throughout
