- 借库申请按 (name, spec_model) 发起，审批明细无 sku 字段； 旧代码用 sku 做 key 会导致所有条目坍塌到同一桶，校验形同虚设 - 改为在扫码循环内即时累加、即时拦截： 防线4 锁定 stock 行后从 material_base 取真实 (name, spec_model)， 与审批单按 strip 后的 (name, spec_model) 聚合比对 - 新增 joinedload(ModelClass.base) 一次 JOIN 加载 base， 避免循环内 stock.base 触发 N+1 - 修正 dispatch_borrow docstring 中"sku 用于超额交叉校验"的错误描述
