## Key Statistics

### Error Distribution

| Category | Count | % | Priority |
|----------|-------|---|----------|
| Missing fields (E0560) | 110 | 48.9% | CRITICAL |
| Field access (E0609) | 44 | 19.6% | HIGH |
| Missing methods (E0599) | 32 | 14.2% | HIGH |
| Type mismatches (E0308) | 18 | 8.0% | MEDIUM |
| Private fields (E0616) | 12 | 5.3% | MEDIUM |

| **TOTAL** | **225** | **100%** | - |

### The 20/80 Rule

**6 root causes → 186 errors (82.7%)**:
1. DeltaSigmaProposal struct (30 errors - 13.3%)
2. Observation struct (18 errors - 8.0%)
3. ObservationSource enum (16 errors - 7.1%)
4. ValidationContext struct (10 errors - 4.4%)
5. ValidationEvidence struct (9 errors - 4.0%)
6. PatternType enum (8 errors - 3.6%)

**Fix these 6 → Resolve 82.7% of all errors**

## Verification Checkpoints

After each phase, verify:

```bash
# Error count check
cargo make check 2>&1 | grep -c "error:"

# Expected counts:
# Start: 225
# After Phase 1: ~134 (-91)
# After Phase 2: ~110 (-24)
# After Phase 3: ~89 (-21)
# After Phase 4: 0 (-89) ✅

# Final verification
cargo make test  # All tests compile
cargo make lint  # No clippy warnings
cargo make ci    # Full pipeline passes
```
