#### 1.3 Update Operation
✅ **TC-UPDATE-01**: Passed - Update operation modifies existing value
✅ **TC-UPDATE-02**: Passed - Raises NotFound for non-existent key
✅ **TC-UPDATE-03**: Passed - Raises AccessDenied for unauthorized user
✅ **TC-UPDATE-04**: Passed - Raises EncryptionError when encryption fails
✅ **TC-UPDATE-05**: Passed - Raises ValueError for invalid key

#### 1.4 Delete Operation
✅ **TC-DELETE-01**: Passed - Delete operation removes key-value pair

### 2. Transaction Support
✅ **TC-TRANS-01**: Passed - Transaction commit persists changes
✅ **TC-TRANS-02**: Passed - Transaction rollback reverts changes

### 3. Performance Benchmarks
✅ **TC-PERF-01**: Passed - Single operation latency measured (see benchmarks/sqlite_performance.md)
✅ **TC-PERF-02**: Passed - Bulk operation throughput measured
✅ **TC-PERF-03**: Passed - Transaction performance measured
✅ **TC-PERF-04**: Passed - Memory usage patterns documented

### 4. Security Compliance
✅ **TC-SEC-01**: Passed - Data is encrypted with AES-256-GCM
✅ **TC-SEC-02**: Passed - RBAC integration works correctly
✅ **TC-SEC-03**: Passed - Audit logging is implemented

### 5. Test Coverage
✅ **TC-COV-01**: Passed - 100% coverage achieved for new functionality

## Issues Found

### RBAC Parameter Order Issue
**Description**: The SQLite adapter was calling `validate_permission()` with incorrect parameter order (user_id first) compared to the RBAC engine's expected order (resource first).

**Resolution**: Fixed parameter order in all calls to match RBAC engine interface.

**Impact**: Low - Caught during testing before deployment

### Missing grant_permission Method
**Description**: Tests were attempting to use `grant_permission()` method which doesn't exist in RBACEngine.

**Resolution**: Updated tests to use `assign_role()` instead, as permissions are role-based.

**Impact**: Medium - Required test updates but didn't affect production code

## Performance Characteristics
Key performance metrics from benchmarks/sqlite_performance.md:

| Metric          | SQLite Adapter | Memory Adapter | Overhead |
|-----------------|---------------:|---------------:|---------:|
| Single op latency | 15.3 μs       | 1.2 μs        | 12.8x    |
| Bulk throughput  | 6,200 ops/sec | 85,000 ops/sec | 13.7x    |
| Memory usage (100k ops) | 14.3 MB | 1,402.1 MB | -98%     |

**Recommendation**: Use SQLite adapter for:
- Large datasets where memory is a concern
- Applications requiring persistence
- Scenarios needing transaction support

## Security Validation
All security requirements from specs/security.md are met:
- AES-256-GCM encryption
- RBAC integration with signed OU claims
- Audit logging with integrity protection
- Certificate pinning support

## Final Status
✅ **PASSED** - All requirements verified and implementation matches specifications

## Next Steps
1. Security specialist review (Goal-4-Task-4)
2. Integration testing with other components
3. Performance optimization if needed
4. Documentation updates
