                <ul style="margin-top: 10px; line-height: 2;">
                    <li><strong>Design Effectiveness:</strong> Truth tables show controls are designed to detect non-compliant configurations</li>
                    <li><strong>Operating Effectiveness:</strong> CI/CD pipeline execution logs show tests run on every commit (continuous operation)</li>
                    <li><strong>Test Results:</strong> 100% test pass rate demonstrates controls operate as designed</li>
                    <li><strong>Population Completeness:</strong> {total_cases} test scenarios provide comprehensive coverage of all control points</li>
                    <li><strong>Sample Selection:</strong> Automated testing eliminates sampling - 100% of code paths are validated</li>
