## Next Milestones
```
Immediate (Next Session):
▶ Scale Harness 2: 30K → 50K iterations (16.7%)
▶ Scale Harness 3: 300 → 1K iterations (1%)
▶ Expand Harness 1: 100 → 150 tests (7.5%)
Short-term (This Week):
▶ Fix parser limitations (32h, 5 tickets)
▶ Integrate type checker (middleend/infer.rs)
▶ Integrate optimizer (real transformations)
Medium-term (Next 2 Weeks):
▶ Begin Harness 4: Runtime Anomaly Tests
▶ Begin Harness 5: Coverage-Guided Fuzzing
▶ Scale all harnesses to 10% targets
