## Overall Coverage
- Target: >= 90%
- Current: 88.5%
- Status: ⚠ Below Target

## Module Coverage

| Module | Coverage | Status |
|--------|----------|--------|
| medical_records | 95% | ✓ Excellent |
| identity_registry | 90% | ✓ Good |
| governor | 88% | ⚠ Good |
| meta_tx_forwarder | 85% | ⚠ Good |
| medical_consent_nft | 82% | ⚠ Fair |
| escrow | 78% | ⚠ Fair |
| cross_chain_bridge | 75% | ⚠ Fair |
| predictive_analytics | 70% | ⚠ Needs Work |

## Coverage by Function

### Critical Path Functions (100% coverage required)
- ✓ initialize()
- ✓ create_record()
- ✓ grant_access()
- ✓ revoke_access()

### Important Functions (>= 95% coverage required)
- ✓ validate_user()
- ✓ check_permissions()
- ✓ audit_log()

### Standard Functions (>= 80% coverage required)
- ⚠ get_record_history() - 78%
- ⚠ calculate_fees() - 75%
- ✓ format_output() - 92%

## Uncovered Lines

### Critical Gaps
- \`/src/predictive_analytics/mod.rs\` (Lines 45-89): 44 lines uncovered
- \`/src/cross_chain_bridge/mod.rs\` (Lines 120-156): 36 lines uncovered

### Recommendations
1. Add tests for error handling paths
2. Cover edge cases in data validation
3. Test cross-chain scenarios
4. Add integration tests for analytics module

## Test Execution Time
- Unit Tests: 35 seconds
