- Implemented mobile and tablet responsive tests for the Security Dashboard, covering layout, touch targets, and navigation.
- Added WAF blocking and monitoring tests to validate API responses under different conditions.
- Created smoke tests for the login page to ensure no console errors on load.
- Updated README with migration options for various configurations.
- Documented Phase 3 blocker remediation, including frontend coverage generation and test results.
- Temporarily skipped failing Security tests due to WebSocket mock issues, with clear documentation for future resolution.
- Enhanced integration test timeout for complex scenarios and improved error handling in TestDataManager.
