// Enhanced End-to-End Tests for Issue 016: HMMM → SLURP → UCXL Decision Workflows
// This comprehensive test suite validates the complete end-to-end workflow from HMMM
// discussions through SLURP event processing to UCXL decision storage and retrieval,
// with comprehensive role-based collaboration, load testing, and error resilience.
//
// Key Enhancements:
// - Role-based HMMM discussion simulation with realistic collaboration patterns
// - Advanced SLURP processing with idempotency, backpressure, and DLQ handling
// - Comprehensive UCXL decision publishing with temporal navigation
// - Load testing with various traffic patterns and stress scenarios
// - Error injection and recovery testing with circuit breaker validation
// - Performance monitoring and SLO validation
// - Cross-system integration validation with audit trails
