## Known Issues and Limitations

### ⚠️ Test Environment

1. **Garbage Collection**: Tests require `--expose-gc` flag for memory leak detection
2. **Test Isolation**: Some tests may interfere if run in parallel (use `--runInBand`)
3. **Timing Sensitivity**: Performance tests may vary based on system load

### 🔧 Workarounds

```bash
# For stable performance tests
node --expose-gc --max-old-space-size=1024 node_modules/.bin/jest \
  tests/integration/phase2/phase2-performance-benchmarks.test.ts \
  --runInBand

# For memory leak tests
node --expose-gc --max-old-space-size=1024 node_modules/.bin/jest \
  tests/integration/phase2/phase2-resource-usage.test.ts \
  --runInBand --detectLeaks
```
