+修正“休眠账户大额启用”在项目流水不完整时的误报，并在结果总览异常账户数据中透出命中原因和涉及金额。
+
+## 实施范围
+
+- 调整 `DORMANT_ACCOUNT_LARGE_ACTIVATION` SQL：项目流水最早日期必须覆盖启用日前 6 个月观察窗口。
+- 调整 `SUDDEN_ACCOUNT_CLOSURE` SQL：销户前 30 天窗口内需存在大额资金流动，避免普通销户前交易被判定为异常账户线索。
+- 异常账户分页和导出查询增加 `reasonDetail`、`involvedAmount`。
+- 风险明细工作簿和 PDF 报告的异常账户表增加“命中原因”“涉及金额”。
+- 新增规则元数据增量 SQL，同步“突然销户”业务口径。
+- 更新后端单元测试断言。
+
+## 不包含
+
+- 不开发非实控账户规则。
+- 不新增“关联员工”列。
+- 不新增“销户后交易”校验类场景。
+
+## 验证
+
+- 执行异常账户规则、结果总览 Mapper、导出器相关测试。

+## 修改内容
+
+- 修正 `休眠账户大额启用`：项目流水必须覆盖启用日前完整 6 个月观察窗口，避免仅导入某日起流水时误判为首次启用。
+- 收紧 `突然销户`：销户前 30 天窗口内需满足累计交易金额 50 万以上或单笔最大金额 10 万以上，避免普通销户前交易被误判为异常账户线索。

+
+## 影响范围
+
+- 影响异常账户模型规则 `DORMANT_ACCOUNT_LARGE_ACTIVATION` 的命中口径。
+- 影响异常账户模型规则 `SUDDEN_ACCOUNT_CLOSURE` 的命中口径。
+- 影响结果总览异常账户分页接口、统一风险明细导出和 PDF 报告。
+- 不涉及非实控账户规则，不增加关联员工展示。
