Simulation: Chef {config.chef_version} → AAP {config.target_version}
✓ Configured for production environment
✓ {mock_chef_response["total"]} nodes migrated to Ansible inventory
✓ Execution environment created with EE-based model (not legacy virtualenv)
✓ Job template configured with content signing for supply chain security
✓ FIPS compliance enabled
✓ Ansible {config.ansible_version} core version requirement met
Next steps:
1. Execute migration with mocked APIs
2. Run generated playbook: {mock_jt_response["playbook"]}
3. Validate against {len(config.available_endpoints)} available AAP 2.4 endpoints
4. Deploy to production
