 - “待人工核对”表示订单结果不明确，必须先人工核查并禁止自动重试；“采购成功”表示已取得 PDD 订单号和下单时间，不代表已经支付。
 - 一个 PDD 订单号只能属于一个采购任务，该唯一性在采购任务保存路径上全局强制（#241）。人工处理结果未知、取消及 lifecycle 保存路径撞号时返回 `PURCHASE_ORDER_NUMBER_ALREADY_USED`，提示订单号已属于哪个任务，由采购员人工核对，不静默覆盖原值。
 - 不可逆边界之后的 `order_created` 结果回传是上述规则的例外：此时 PDD 真单已创建，发现订单号已属于其他任务时不回滚、不判失败，而是把任务降级为 `order_result_unknown`，冲突订单号以「读到订单号 X，但该号已属于任务 CG-yy」保存在任务与 attempt 的 `error_message`，`pdd_order_no` 留空以维持唯一性，保留下单时间与不可逆时间，进入既有人工处理结果未知通道。首要目标是保住「真单已存在」这一事实，不制造无记录的真实订单。
- Agent 可按收货地址后缀 `_cg<任务号>` 批量回填订单号与下单时间（#241）。后缀只承载任务号，请求不含地址全文或收件人信息；只允许回填该设备自己的正式采购任务；页面下单时间优先，缺失时回落该任务的 `irreversible_at` 并标记时间来源，两者皆空则该条失败。
+- Agent 可按收货地址后缀 `_cg<任务号>` 批量回填订单号与下单时间（#241）。
+- Agent 侧回填为**人工触发的只读扫描**（#242）：入口在采购记录页搜索按钮右侧，输入天数（默认 2）后确认启动。天数口径为滚动 N×24 小时，基准是页面读到的下单时间。采集、采购、回填三者互斥，复用既有任务互斥锁并加原子防重入，忙碌时拒绝启动而不排队、不抢占。
+- 回填扫描不假设订单列表有序：只有连续观察到至少 5 单且下单时间严格递减、期间无缺失时间时，才允许「超过指定时间即停止」；一旦出现时间回升或缺失，改为扫至内部上限并明确标记「未完整扫描」，不得把不完整结果显示为已扫完。内部上限用于限制设备占用，不作为用户可配置的门禁。
+- 回填扫描全程只读：确认收货、申请退款、催发货、去支付、立即支付、提交订单、付款、退款、取消订单、再次购买、删除订单永久排除为点击目标；点击目标必须自身可点、子树不含上述词，且不与任何含上述词的可见控件几何重叠；不得按固定坐标盲点。遇登录、验证码或风控立即停止并报告。
+- 解析不出规范后缀的订单一律跳过，其订单数据不缓存、不上传、不入日志；上传载荷只含后缀、订单号与可选下单时间。本地缓存只采纳服务端确认的事实，并区分页面读到的真实时间与 `irreversible_at` 回落估算值。后缀只承载任务号，请求不含地址全文或收件人信息；只允许回填该设备自己的正式采购任务；页面下单时间优先，缺失时回落该任务的 `irreversible_at` 并标记时间来源，两者皆空则该条失败。
 - 已失败、已取消或演练完成的旧采购任务不单独占用主阶段；当前数据仍满足条件时恢复显示“可创建采购”，旧任务继续在采购管理留痕和按既有规则处理。
 - 未选择处理阶段时，商品列表仍先返回，当前页阶段和采购准备继续异步批量读取且不调用 AI Provider；选择阶段筛选时，服务端必须先对完整查询结果派生并筛选阶段，再计算总数和分页，不能只过滤当前页。

-
-requestId 沿用 UUID 约定，不增加批次表或全局幂等缓存。既有 unknown_resolve_request_id 槽存储 `backfill:<page|irreversible_at>:<由 requestId 和后缀派生的 UUID>`（最多 61 字符），用于任务级关联和保留本功能时间来源。相同任务和订单号即使更换 requestId 也无写入；同 requestId 改内容仍重新执行设备、状态和订单冲突检查，不凭 requestId 直接放行。批内不同任务提交同一订单号时，先成功提交者占用，其余条目返回订单已被使用；已存在的历史重复订单号不自动修复。
-
-订单号尚无唯一索引，本实现不迁移数据库。共享模型保存钩子复用 `purchase_rule_setting.id=1` 行作短事务互斥锁，再以锁定读检查订单号归属，覆盖回填、原人工解除和旧结果提交路径；单例缺失时拒绝写入，数据库死锁时回滚失败事务。原 ResolveUnknown 与 Admin 鉴权代码保持不变。禁止通过跳过模型钩子的直接 SQL 写入宣称具备此保证。
-
-新回填路径禁用包含绑定参数的 SQL 日志，不记录请求正文、订单号、地址或原始树；任务号和认证设备号沿既有任务关联不可变 ruleSnapshot。此接口未新增日志载荷或任务/attempt。

-自 #239（实现提交 c6a962d，已于 2026-09-08 随 d403f3b 部署线上）起，改为按页验证和保存：每页先验证条数、合法 ID、页内/跨页重复，再按冻结店铺快照获取并验证全部明细；外部请求完成后才开启页事务。页内任一入库失败回滚整页，已提交的前页保留，计数在事务提交后累计。
