 分支 fix/325-order-result，2026-09-19，尚未发布及真实下单验收。PurchaseLiveAutomation.readOrderResult 采用25次支付页返回后采样、首次待付款页独立30次采样/最多4次按需滑动；原过渡60次与总90次采样上限保留有界终止。parsePayableAmount只从本次只读标签集合提取明确应付总额。
 
 数据链路：PurchaseOrderEvidence.pddOrderAmountCent → PurchaseExecutionOutcome → service/PurchaseResultPayload.kt → purchase.ResultRequest → lifecycle.go 的 order_created 分支 → 既有 purchase_task.pdd_order_amount_cent。重启只读核单也沿用同一可选字段。复用已有结果Outbox、幂等哈希和订单号唯一性；不新增表、配置、任务或SYB金额字段。未修改我的订单回填、Chrome扩展和Web，不能将旧入口的实付含义描述为本次已改成应付。
+
+## Admin 订单资料补全与一致回填资格（#326）
+
+实现3a2472d（2026-09-19），Server/Web，未合并发布；无迁移、无Android/插件改动。
+
+- purchase/types.go ManualRequest 增加可选 pddOrderAmountCent；manual.go ResolveUnknown 复用既有行锁事务和模型单号保护，扩展为未知结果确认或已创建订单补缺。仅此操作启用新增重放内容校验和事务内 ensureOrderWriteback，其他人工付款/取消/授权流程不新增入队副作用。
+- order_writeback.go 的任务资格去掉 order_created 限制；validOrderWritebackTarget 统一有效 stock/detail 边界。OrderWritebackViews 一次批量读取关联而非逐行查询，RequestOrderWriteback 和 worker 执行前再次检查。队列结构、租约、外部写入协议不变。
+- web/src/views/goauto/purchase-tasks/index.vue 沿用原详情/弹窗/resolve-unknown API，新增缺字段补录入口、整数分转换、完整性展示及失败保留输入，不增加数据库状态或新的权限资源。旧未知结果请求不带金额继续兼容。
+- 回归：server go test -p 1 ./app/goauto/purchase ./app/goauto/clientapi ./app/goauto/sybclient；Web 生产构建及 tests/e2e/purchase-order-writeback.spec.ts 的6项隔离浏览器测试。真实SYB接口用fake/httptest替代，未执行付款、采购或线上写入。

 过渡阶段最多60次采样。首次识别到待付款证据后单独分配30次采样预算，不被之前绕路消耗，不因文字反复出现重置；核单总采样上限90次。缺少唯一订单号或时间时立即向上滑动读取下方内容，最多4次、手势400ms、每次后等500ms；读全立即停止，已有完整字段不滑动。该待付款读取分支不点击任何控件，也不点击付款。纯支付页不使用该滑动分支；出现可读待付款证据优先于复用的 Activity 名称。按采样间隔约18秒加有限手势/额外等待，实际耗时还含capture等调用；未改变2分钟任务租约或5分钟唤醒锁，也不宣称新增了执行器总体墙钟超时机制。
 
 应付金额从同一订单的可见标签集合中读取，兼容“应付:,13元”等标点；不跨无关联节点拼接，不读拼单价、优惠或实付。父子重复同金额去重，多值/缺失/无效/溢出省略，不因金额失败丢弃订单号与时间。仅存Admin，不推断支付、不改SYB金额、不修改地址行为。历史回填及界面语义未在本单统一，详见API契约#325补充。

+
+采购任务保存 PDD 订单号、下单时间和订单金额即为资料完整，不检查是否已付款；金额0元有效。复用 pddOrderNo/orderSubmittedAt/pddOrderAmountCent，金额以人民币分存储。order_created 不改义，仍是已创建订单事实；缺金额展示“订单信息待补全”，不能当作采购失败再次下单。页面统一称“订单金额”，其来源可能是#325应付或既有回填实付，不能将历史值统一称已付金额。
+
+Admin 复用未知结果处理弹窗增加金额输入，并为 live 已创建且缺资料任务提供“补全订单信息”；已有字段只读、缺项可填。保存中禁用提交，失败保留输入；沿用既有权限，不增加审批。非执行中的未知结果人工确认与已有订单资料补全都会事务内保证单号回填记录，不修改支付复核或触发设备操作。
+
+SYB 回填与资料完整性独立：正式SYB任务已有单号且仍关联有效明细即可入队，不要求 order_created 状态、时间、金额、付款确认或地址后缀。只有订单号上传SYB；沿用同号成功、异号冲突不覆盖及既有在途防重复规则，不倒扫历史任务。历史补偿仍手动勾选，已成功或在途任务不可重复发起。
+
+自动下单读取和Admin补录是后续目标来源；本单尚未删除插件或Agent我的订单回填，不能宣称上游地址后缀已取消或历史错误归属已修复。金额缺失不得自动采购，订单号唯一归属保护和永久不付款规则不变。
