+# 短时间多次存现本人口径调整实施记录
+
+## 修改内容
+
+- 调整后端大额交易模型规则 `FREQUENT_CASH_DEPOSIT`。
+- 删除规则 SQL 中关系人流水 `UNION ALL` 分支。
+- 规则现仅统计员工本人流水，即 `ccdi_base_staff.id_card = ccdi_bank_statement.cret_no`。
+
+## 影响范围
+
+- 影响文件：`ccdi-project/src/main/resources/mapper/ccdi/project/CcdiBankTagAnalysisMapper.xml`。
+- 影响规则：短时间多次存现。
+- 配偶、父母、子女等员工关系人流水不再自动归集到员工本人名下触发该规则。
+- 已生成的历史打标结果不会自动变化，需要重新执行项目分析/打标后生效。
+
+## 验证情况
+
+- 已检查 `selectFrequentCashDepositObjects` 规则片段，确认仅保留员工本人分支。
+- 已执行 `mvn -pl ccdi-project -am compile -DskipTests`，编译通过。
+- 已通过 `output/frequent_cash_deposit_self_only_verification.sql` 写入临时验证数据并执行规则等价 SQL：
+  - 员工 A 本人 3 笔存现，命中员工 A。
+  - 配偶 B 同时也是员工，B 本人 3 笔存现，命中员工 B。
+  - 当前本人口径不会把 B 的流水归集到员工 A。
+  - 对照旧关系人分支会额外命中员工 A，验证本次删除关系人分支有效。
+- 验证脚本末尾已清理临时员工、关系人与流水数据，并复查三张表残留数均为 0。
