## Summary

## Recommendations

### Failed Tests Analysis

- **${test.name}**: ${test.error?.message || `HTTP ${test.status}`}

### Next Steps
1. Check server logs for detailed error information
2. Verify tRPC router configuration
3. Ensure all required dependencies are installed
4. Validate environment configuration
5. Test endpoints manually if needed
`
    : `
### Optimization Opportunities
1. Monitor response times for performance optimization
2. Consider implementing caching for frequently accessed endpoints
3. Add monitoring and alerting for endpoint health
4. Implement rate limiting if not already in place
