   • Impact: 5,000+ lines untested
   • Fix: Implement 100+ test cases (see test files in tests/unit/quality-validator/)

2. Pyodide Runner: 9.7% coverage ⚠️ CRITICAL

   • Location: src/lib/pyodide-runner.ts
   • Lines: 1-42, 45-93, 102-223
   • Fix: Add integration tests for Python execution

3. IndexedDB Storage: 25.31% coverage ⚠️ CRITICAL

   • Location: src/lib/indexeddb-storage.ts
   • Fix: Add database operation tests

4. Storage Utility: 75.75% coverage ⚠️ MEDIUM

   • Location: src/lib/storage.ts
   • Fix: Cover error cases and edge cases

5. Middleware: 70.41% coverage ⚠️ MEDIUM

   • Location: src/store/middleware/
   • Fix: Test persistence configuration

Test Effectiveness

• Assertion Density: Good (multiple assertions per test)
• Mocking: Excellent (proper mocking for external dependencies)
• Isolation: Good (tests properly isolated)

🔒 SECURITY ANALYSIS

Vulnerability Scan Results

npm audit Status:
├─ Critical:  1 ❌ REQUIRES ACTION
├─ High:      0 ✓
├─ Medium:    2 ⚠️  Review
└─ Low:       3 ℹ️  Monitor

Identified Vulnerabilities
