#### 📏 Size Metrics

Total Lines: 1417

Total Cells: 17

Avg Cell Length: 65.3 lines

#### 🎯 Quality Metrics

Scaffolding Quality: 3/5

Learning Progression: 4/5

Concepts Covered: 60

#### 🎯 vs Targets

❌ Too long (1417 lines, target: 200-400)

❌ Too long (65.3 avg, target: ≤30)

✅ Good (17.6% high-complexity)

#### 🚨 Critical Issues

- Module too long (1417 lines) - students will be overwhelmed
- 8 cells are too long (>50 lines)

#### 💡 Recommendations

- Break module into smaller sections or multiple modules
- Split 12 long cells into smaller, focused cells
- Add immediate feedback tests after implementations
