 ## 费用付款与凭证快速入口
 
-- 入库费用的应付/直接已付表单在 `../unified-orders/components/InboundFeeDetailManager.vue`，柜次费用在 `../loading-lists/components/ContainerFeesPanel.vue`；对应 API 分别为 `../unified-orders/api/inboundFeeDetails.ts`、`../loading-lists/api/containerFees.ts`。
+- 入库费用的应付/直接已付表单在 `../unified-orders/components/InboundFeeDetailManager.vue`，柜次费用在 `../loading-lists/components/ContainerFeesPanel.vue`；柜级公共费用在同一面板按真实客户与订单分摊，入仓码按事实选填；对应 API 分别为 `../unified-orders/api/inboundFeeDetails.ts`、`../loading-lists/api/containerFees.ts`。
 - `DIRECT_PAID` 必须提交已付时间、付款方式，以及付款流水号或至少一个付款凭证；凭证由费用 API 调用 `/platform/finance/v1/vouchers` 上传为 `FINANCE_VOUCHER`，并绑定当前客户。
 - 后端事实入口为 Firstleg `FeePaymentSnapshotValidator`、入库/柜次费用服务，文件元数据归 File；Finance 只消费已发布的费用来源快照，不在前端或 Finance 中重建付款事实。
