# RBAC Performance Testing Handoff

## Issue Summary
Performance tests for RBAC are failing due to missing `audit_sequence` attribute in RBACEngine class. This prevents the audit logging functionality from working, which is required for role assignment operations.

## Error Details
```
AttributeError: 'RBACEngine' object has no attribute 'audit_sequence'
File: security/rbac_engine.py:703
```

## Affected Tests
1. test_role_resolution_latency
2. test_permission_check_throughput  
3. test_concurrent_sessions
4. test_memory_usage

## Expected Behavior
RBACEngine should maintain an audit sequence counter for tracking access attempts.

## Next Steps
Security team needs to:
1. Add audit_sequence initialization to RBACEngine
2. Verify audit logging functionality
3. Confirm performance tests pass after fix
