 ## 3.7 Word 渲染
 
 - 新增依赖：`poi-tl 1.10.4`（兼容 POI 4.1.2）、`jfreechart 1.5.4`；禁止再引入 docx4j。
-- 模板：`DEVICE_CRACK_METER_V1.docx` 等，按 `template_code + category` 定位（`report_template` 表）。
+- 模板：`DEVICE_CRACK_METER_V2.docx` 等，按 `template_code`（`DEVICE_${CATEGORY}_V2`）从 classpath 的 `templates/` 目录加载（`DefaultWordTemplateResolver`）。模板与渲染逻辑强耦合，**不入库**，随代码版本发布。
 - 变量：`{{report.no}}`、`{{report.periodDesc}}`、`{{device.name}}`、`{{device.serialNumber}}`、`{{analysis.statistics.max}}`、`{{analysis.statistics.delta}}`、`{{analysis.trend.description}}`、`{{analysis.warning.status}}`、循环表格 `{{conclusions}}`、图片 `{{charts.crackTrend}}` 等；模板不直接绑定数据库字段。
