 - 只接受冻结契约支持的事件类型和版本；校验事件 ID、租户、区域、Payload 哈希及必要字段。
@@ -43,8 +59,8 @@
 - 平台查询范围由可信身份/平台权限决定；商户查询只能使用认证身份中的客户 ID。
 - 列表、详情、导出和更新必须使用同一租户边界，不能仅在列表过滤而让详情或更新越权。
 - 目的仓变更必须写状态/操作历史或审计证据，并使用版本控制防止并发覆盖。
-- 货物废弃只使用可核对 SKU 和箱唛的一件代发库存；提交申请时将箱锁定为 `DISCARD_PENDING`，具备 `lastleg:cargo-discard:approve` 权限的审核人通过后才扣减 SKU 箱数并写逐箱流水，拒绝时释放锁箱。
-- 海外采购客户下单固定进入 `PENDING_REVIEW`；审核通过后后台才可维护入库量和新增出库记录。采购库存固定按 `inbound_quantity - outbound_quantity` 计算，禁止直接覆盖库存量或产生负库存；审核、编辑和出库均须按可信租户范围执行。
+- 货物废弃只使用可核对 SKU 和箱唛的一件代发库存。创建申请只能将箱从 `AVAILABLE` 锁定为 `DISCARD_PENDING`，不得扣减 SKU 箱数；实际扣库存节点固定为具备 `lastleg:cargo-discard:approve` 权限的仓库/PDA 审核人确认废弃时，并且必须在审核事务内调用专用 discard adjustment。该 adjustment 必须将箱改为 `DISCARDED`、写逐箱业务流水及唯一幂等键，并校验 `扣减前箱数 - 废弃箱数 = 扣减后箱数` 且逐箱数等于申请总箱数；任一环节失败须整体回滚。拒绝申请只释放锁箱，不得扣库存。
+- 海外采购客户下单固定进入 `PENDING_REVIEW`；采购表的 `inbound_quantity - outbound_quantity` 只表示采购业务单据余量，不得写入或冒充 `available_packages`。审核/下单只能停留在采购单据（或明确的 `procurement_packages` 桶）；只有海外仓 PDA 完成实收后，`InboundStockReceiptService` 才能以 `PDA_STOCK_IN:{taskId}:{allocationId}` 幂等键调用库存 `stockIn` 转入可用库存。禁止通过通用平台接口绕过 PDA 入可用库存。
