- * E2E Workflow Coverage:
- * 1. RFA submit → Review Tasks created (parallel)
- * 2. All reviewers complete → Consensus evaluated
- * 3. Consensus APPROVED → Distribution queued
- * 4. Distribution processed → Transmittal created
- * 5. Veto (Code 3) → PM override → force APPROVED
- * 6. Reminder sent when task overdue
- * 7. Delegation: delegate completes task on behalf
