+# REV-004 未销水量调整零水量与补抄追收验证记录
+
+## 变更范围
+
+- 按水量调整预算允许 `targetBillWater=0`，仍拒绝负数水量。
+- 正式水量调整默认保留“调整后水量不能超过抄见水量”限制。
+- 当原因编码或原因说明属于补抄、追收、漏抄、少抄、估抄偏低、补征等场景时，允许目标水量超过原抄见水量。
+
+## 验证命令
+
+```bash
+mvn -pl sw-business/sw-business-server -am \
+  -Dtest=UnsoldTrialPreviewServiceImplTest,ChargeServiceAccountingAdjustTest \
+  -Dsurefire.failIfNoSpecifiedTests=false test
+```
+
+## 验证结果
+
+- `UnsoldTrialPreviewServiceImplTest`: 12 tests, 0 failures, 0 errors.
+- `ChargeServiceAccountingAdjustTest`: 24 tests, 0 failures, 0 errors.
+- Maven reactor: `BUILD SUCCESS`.
+
+## 风险说明
+
+- 本次未放开已收费、已开票、已结账、缺少抄表依据、缺少附件等既有校验。
+- 补抄追收白名单为后端兼容策略，后续可在正式原因字典稳定后收敛为字典值校验。
