• Implement tagging, traceability, and audit logging mechanisms to meet compliance standards.
• Collaborate with compliance stakeholders to validate traceability from test case ? defect ? requirement.
• Validate backend data flows across SOR, Domains, and Read Store using structured test data from TDP and synthetic fallback pools.
