### 1. 仅提取第一个 measurement
- **依据**：只提取 MRO XML 中第一个 `measurement`，忽略后续的 PLR、RIP 等。实现方式为使用 `lxml.iterparse`，在解析到第二个 `<measurement>` 时立即停止。 *(来源 `memory:b882fb0f-554f-43fb-80d7-bd4855d3db2f`)*

### 2. 字段前缀处理
- 去掉所有 `MR.` 前缀，仅保留实际字段名。 *(来源 `memory:239b53ab-c40a-4c6f-978f-f5e97d45f49f`)*

### 3. CSV 编码与命名
- 使用 GBK 编码以兼容 Windows 控制台。
- 输出文件命名为 `MRO_<时间戳>.csv`（精确到秒），放置于 `output/`。 *(来源 `memory:239b53ab-c40a-4c6f-978f-f5e97d45f49f`)*

### 4. 保持现有目录结构与依赖
- 项目已配备 `.venv` 与 `lxml==6.1.1`，不添加额外依赖，遵循全局开发原则 **KISS 与 YAGNI**。 *(来源 `memory:bf88c265-4749-4c50-85bc-4bae25298cd5`)*
