+# add-ledger 模块说明
+
+## 模块定位
+
+`add-ledger` 是 `tools` 下的数据台账配置工具模块，当前基于 `ledger.sql` 中的工程、项目、设备、监测点和台账树表结构，提供后端配置接口。
+
+本次范围不包含：
+
+- 前端真实页面代码
+- 自动执行 SQL 初始化
+- 自动数据库迁移
+- 设备通信、WebSocket 或 Netty 链路改造
+
+目录中的 `ledger.sql` 仅作为原始表结构脚本保留，当前模块不加载、不解析该脚本。

+  - 新增或保存测点，并同步 `cs_ledger` 测点节点。
+- `GET /addLedger/line/availableLineNos`
+  - 查询设备下 `1-20` 中可用的线路号。
+- `DELETE /addLedger/node`
+  - 软删除指定节点，父节点会级联软删除下级业务数据和台账节点。
+
+## 实现说明
+
+- 台账层级固定为：工程 -> 项目 -> 设备 -> 监测点。
+- 新增时绑定父级节点；编辑时只更新当前业务数据和台账节点名称，不搬迁节点。
+- 保存业务表和 `cs_ledger` 在同一事务内完成。
+- 设备保存时同步 `associated_engineering` 和 `associated_project`。
+- 测点新增时生成 32 位 UUID 作为 `line_id`。
+- 测点 `line_no` 后端限制为 `1-20`，且同设备下正常测点不可重复。
+- 删除采用软删除：工程、项目、测点更新 `status=0`，设备更新 `run_status=0`，台账节点更新 `State=0`。
+
+## 后续扩展约束
+
+后续如果新增更多台账能力，应沿当前 `controller -> service -> mapper -> XML` 职责边界扩展，不回退为单一大类承载全部接口。
