- Enhanced test run template with telemetry and state verification
- Documented state integrity checks (content hash, schedule hash)
- Added UI indicators and persistent test artifacts requirements

Documentation Updates:
- Enhanced IOS_PREFETCH_TESTING.md with comprehensive test strategies
- Added Technical Correctness Requirements to IOS_TEST_APP_REQUIREMENTS.md
- Expanded error handling test cases from 2 to 7 scenarios
- Created ENHANCEMENTS_APPLIED.md summary document
