// 实物库存批次服务
|

// 职责：CRUD、移库(MoveStock库位间)、调拨(TransferStock仓库间)、出库(Outbound)
|
||||
// 调用链：Controller → Create/Update/Delete → Capacity.UpdateLocationCapacity(容量重算)
|
||||
// 紧密耦合：dao.PrivateStock、dao.Warehouse/Zone/Location(获取名称)、Capacity(容量更新)
|
||||
// 注意：区别于StockDetails/StockBatch的逻辑库存，PrivateStock记录实际存放位置
