RepairPlan[repairTarget=修复 OrderService.calculateDiscountPrice 的 double 精度丢失问题, rootCauseHypothesis=calculateDiscountPrice 使用 double 做中间运算，导致浮点精度丢失，应全程使用 BigDecimal。, suspectedFiles=[target-service/src/main/java/com/example/targetservice/service/OrderService.java, target-service/src/test/java/com/example/targetservice/service/OrderServicePrecisionTest.java], steps=[在 calculateDiscountPrice 中移除 doubleValue() 转换，改用 BigDecimal.multiply 进行折扣与数量计算。, 确保返回值由 BigDecimal 运算直接构造，避免 BigDecimal.valueOf(double)。, 运行 target-service 测试验证精度与业务行为。], testCommand=mvn -pl target-service test]

Patch is limited to target-service and tests pass.
