## 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
