Expert Maintenance Capstone: Operating in English Across Systems | 专家维护顶点：用英语跨系统运作
The expert-maintenance test is not whether you know more advanced English. It is whether English remains reliable while several systems, people, sources and decisions interact at once.
This capstone integrates Lessons 101–119. The learner must research, verify, specify, assess risk, plan change, coordinate across teams, communicate uncertainty, record governance, handle failure, transfer knowledge and maintain the system afterward.
这一课检查的是“跨系统稳定性”：当证据、风险、需求、人员、变更、治理、文化差异和故障同时出现时，英语能不能继续保持准确、可追踪、可执行、可恢复。
