+- `shopeeproduct/latest_collection.go` 在原 latestCollection 增加可选 replacement 模式。预览和提交均短事务锁定 SYB、Shopee、原PDD、设备、来源采集与目标PDD，核对旧关联及上下文。提交按预览 taskId 读取，不重新挑选后来采集的商品。
+- Admin 路由注入 `purchase.ValidateQuickReplacement`，在事务内复用采购准备数据集及处理阶段计算，不调用 AI。缺少校验函数拒绝替换；客户端密钥不注入且仍拒绝 latestCollection。无新路由、权限、表或迁移。
+- 关联完成后才执行现有 AI 匹配，不在数据库事务中等待 Provider；同一 SYB 正式采购创建与替换共用 SYB 行锁。历史采购快照不变。SQLite 合成测试覆盖冲突与串行并发请求，不能替代生产 MySQL 多连接锁验收。

+- 修改后不再只见“详细地址”文字就立即写入。最多50次、每次间隔200ms读取（不含读取耗时），检查PDD页面风险；唯一可见启用有内容的详细地址EditText，连续两次路径、边界、内容及Activity相同才继续原输入流程。始终零个/多个或不稳定时失败，不取第一个候选。
+- 输入内容生成、输入后回读、保存后退出及返回规格面板、最终复核和单次下单边界不变。新增本机脱敏诊断 addressEditorCandidates / addressEditorPolls 两个整数，与task/attempt/device/ruleHash关联；不记录地址内容、原始树或整屏截图。

+- 保存地址后的确认读取、必要时一次返回后的确认读取，增加最多50次、间隔200ms的有界就绪检查，页面捕获耗时另计。连续两次同一Activity满足原地址回读与确认面板条件后继续；完整信息不要求滚动区域。已明确到地址列表时保留原返回路径，不等待列表出现下单按钮；返回后增加1000ms缓冲。
+- 就绪检查不修改原地址回读和结构下单入口规则；超时后只对既有识别的面板、唯一可用滚动区域执行原有有限滚动。零/多个区域仍失败，不凭地址入口或未知底部节点授权下单。最终精确规格、数量、价格、地址与单次下单边界不变。
+- 私有采购诊断新增布尔 savedAddressMatched、savedPanelMatched；整数 savedLegacySubmitCandidates、savedAddressCards、savedAddressTargets、savedScrollCandidates、savedConfirmationPolls。只记录标量并绑定task/attempt/device/ruleHash，不保存地址、原始树或整屏图。
+- CG109 v1现场读取未达到空闲状态，不能确认原失败具体缺哪项证据；v2覆盖迟到确认节点及可观测性，不将合成测试通过冒充真机修复验收。无Server/Web/API/迁移/权限变化，不需要服务器重启。

+- 正式阶段消费时检查同任务/商品/规则/设备、前台revision及时间，消费后即清除。失配/超时/无任务或采集任务调度/结果异常/进程重启均不能沿用；普通手动再试不会继承已消费交接。现有服务端租约、互斥和匹配等待策略不变。
+- 有交接时，执行器恢复限定的purchaseEntryContext，最多10次、间隔200ms新读取（捕获耗时另计）；连续两次相同PDD Activity且具备既有商品/面板证据才跳过openProduct。空树可有限等待，其他应用/Activity改变/页面风险立即拒绝复用。没有交接时保留原一次判断路径；不把UNKNOWN当成功，不跳过正式精确规格/数量/价格/地址或下单验证。
+- 私有诊断新增handoffPresent、productReused布尔值，reusePolls整数及reuseReason固定枚举legacy_evidence/page_problem/page_changed/handoff_ready/evidence_timeout。仍绑定task/attempt/device/ruleHash，无敏感文本。
+- 无Server/Web、共享API或数据库变化，不需重启服务器。只有合成测试验证；原CG107/108日志证实两阶段，但未记录旧版重开判断，不把上下文丢失假设宣称为唯一现场根因。

+- 单任务执行开始固定返回次数。完整 completed、服务端提交确认且既有图片上传流程结束后，执行有限 Back，每次后等待 500ms；不要求识别商品/搜索/相机/首页，也不要求画面发生变化。图片上传仍沿用既有非致命行为，不因收尾更改结果。

+
+- 未关联 PDD 且既有处理阶段提供“去关联”的 SYB 行可用一键关联；原人工入口不删除。首次点击选择采集手机后继续当前行，后续使用记忆手机；小箭头查看/切换手机，保存只修改全行共用偏好。取消不改变偏好、不执行关联。与批量采购设备选择互不影响。
+- 以所选手机的临时采集 source=agent_current_page 为范围，从 completed、completed_partial 中按 finished_at DESC、id DESC 取最新一条；失败/待执行/执行中不参与。最新为部分成功或商品停用、无可用规格时明确停止，不回退更旧商品，不切换其他手机。离线手机允许使用已有成功结果，停用或已删除手机需要重新选择。
+- 主动作开始冻结行、蝦皮商品和设备；服务端关联事务固定来源采集任务、PDD商品与规格版本。仅未关联时自动写入，已有或被其他操作改变的关联不覆盖。关联作用于蝦皮商品，因此共用该蝦皮档案的其他 SYB 明细也受影响；切换手机不会重绑已有商品，也不会改变在途操作。
+- 先保存关联，再复用现有颜色/尺码自动匹配及保存。有效已确认映射保留；普通部分匹配保存合格结果，AI故障不提交本轮新映射，但已保存关联保留。后续可从“去匹配”或详情人工继续。failed 且无人工/AI确认时不能自动跳过人工解析；uncertain 不统一拦截，仍以原采购准备规则为准。
+- 操作完成不保证立即可采购，必须刷新现有处理阶段；缺规格、缺映射、解析需确认或其他原资格不满足时继续显示真实待处理阶段。不自动创建采购任务、不下单、不支付。
+- 请求超时/网络中断只做有限回读，不重复提交；读回失败明确结果未确认，避免无限转圈。离开页面不代表后端停止或回滚。普通用户沿用现有采购员权限，无新管理员专属开关。
+
+## SYB 已关联商品的一键替换（#258）
+
+实现绑定 `2b01974`；部署与验收见 #258 发布证据。
+
+- 复用一键关联及小箭头的位置，保留原查看 PDD 商品。PDD 待采集、采集失败、停用或缺价格的对应处理阶段可替换；采集中、已创建/运行采购、成功或结果未知不开放。服务端提交时再次检查，不能只相信按钮。
+- 复用每用户/浏览器/API环境的手机偏好；首次选择继续当前行，小箭头仅切换偏好。预览仅选所选手机最新 completed/completed_partial 临时采集，部分成功或不可用不回退旧商品。确认后固定来源任务和目标，不改用新采集；来源状态、设备、目标规格或旧关联改变时拒绝。
+- 不同商品显示一次确认，包含旧/新商品、手机和共享蝦皮档案影响；取消不写入。同商品不弹替换确认且不重写关联，只继续匹配。共享该蝦皮档案的 SYB 明细使用新关联，历史采购任务快照不改。
+- 沿用既有更换关联和有效映射检查，再复用自动匹配保存。部分匹配、AI失败或解析需人工处理时保留已保存关联，显示真实处理阶段，不保证立即可采购、不自动创建采购。
+- 网络异常只有限回读，区分目标商品、仍为原商品和其他关联，不把“已有某个关联”误报为本次替换成功；不自动重发写请求。没有新增后台作业、订单或付款操作。
+
+## 辅助信息缺失的采集关联（#259）
+
+实现绑定 `e467706`，仅 Server；部署/验收见 #259。替代 #253/#258 中“部分完成一律拒绝”的限制，不改变 completed 原有路径。
+
+- completed_partial 的 missing 必须是非空合法列表且仅包含 salesText、shopName、reviewCount，才进入辅助信息兼容检查；title、规格/价格缺失、遍历截断、SKU数量上限及未知原因仍拒绝。
+- `shopeeproduct/partial_collection.go` 核对本次 task 的维度和值、可售SKU的完整标记/规格引用/非负价格、本次颜色价格，以及当前档案可选值由本次有效SKU覆盖，不能借旧档案合并残留的规格或价格通过。真实单维度允许，不虚构另一维度；本次明确报告缺少规格仍拒绝。
+- 一键关联、替换预览及确认提交共用验证。失败沿用409 LATEST_COLLECTION_UNAVAILABLE及现有提示，不回退更早采集、不换手机。状态 completed_partial 和 missing 原样保留；辅助字段缺失仍可在任务详情查看。
+- 无接口字段、数据库迁移、Android/Web或权限变更；普通人工关联与采购/AI资格不变。不将“允许关联”视为“已匹配或已采购”。
+
+## 采购单标题面板与地址就绪等待（#260、#261）
+
+实现绑定 #260 `3c1ffa4`（执行器回归测试 `7de4318`）、#261 `5ea07f1`，Android 0.9.74 / versionCode87，基于0.9.73。安装及真实采购验收以工单证据为准；不代表 main 的 Android 已整合这些分支。
+
+- 采购仅在安全规格入口点击返回SUCCESS后，记录本次页面包名/Activity作为内存上下文；开始新执行或页面身份改变时清除。`PddScreenParser` 的新增 purchaseEntryContext 默认关闭，仅该采购执行器传入；普通解析和采集原判定保留。
+- 当前仍为同一PDD Activity、商品ID非空、没有页面风险、没有选中摘要，且唯一有标题规格滚动区、一个维度有值，同时具有关闭、数量、支付展示区域与下单操作证据时，单标题可识别为NORMAL_SCROLLABLE。只是允许进入既有精确规格探测/选择，不执行下单或付款，不全局认可UNKNOWN，不增加入口重复点击或滑动。
+- 地址入口点击原有1000ms保留；地址列表等待增加唯一修改目标要求。点击修改和保存由500ms改为1000ms，其他通用动作间隔不变，无新配置项。
+- 修改后不再只见“详细地址”文字就立即写入。最多50次、每次间隔200ms读取（不含读取耗时），检查PDD页面风险；唯一可见启用有内容的详细地址EditText，连续两次路径、边界、内容及Activity相同才继续原输入流程。始终零个/多个或不稳定时失败，不取第一个候选。
+- 输入内容生成、输入后回读、保存后退出及返回规格面板、最终复核和单次下单边界不变。新增本机脱敏诊断 addressEditorCandidates / addressEditorPolls 两个整数，与task/attempt/device/ruleHash关联；不记录地址内容、原始树或整屏截图。
+- 仅Android；无Server/Web、共享API字段、数据库迁移或权限变化。真实采购、地址写入及订单创建不作为自动安装验证，不执行付款。
+
+### v2 商品入口补点与地址返回等待（#260、#261）
+
+2026-09-10 实现绑定 #260 `713111d`、#261 `d0a82f3`，Android 0.9.75 / versionCode88；真实采购效果以工单验收为准，非 main 合并声明。
+
+- 入口恢复不再把全页面支付方式展示文案单独视为支付页。当前包名/Activity、商品标题和安全入口必须与点击前一致，入口唯一且可用；已打开面板、关闭控件、数量、选中摘要、订单操作、风险/评价页面仍拒绝恢复。支付 Activity 或明确支付、订单、地址文本继续阻止补点。仅允许既有一次重新定位后的规格入口中心手势，随后仍验证面板，不循环、不扩展到地址保存或下单。
+- 保存地址后的确认读取、必要时一次返回后的确认读取，增加最多50次、间隔200ms的有界就绪检查，页面捕获耗时另计。连续两次同一Activity满足原地址回读与确认面板条件后继续；完整信息不要求滚动区域。已明确到地址列表时保留原返回路径，不等待列表出现下单按钮；返回后增加1000ms缓冲。
+- 就绪检查不修改原地址回读和结构下单入口规则；超时后只对既有识别的面板、唯一可用滚动区域执行原有有限滚动。零/多个区域仍失败，不凭地址入口或未知底部节点授权下单。最终精确规格、数量、价格、地址与单次下单边界不变。
+- 私有采购诊断新增布尔 savedAddressMatched、savedPanelMatched；整数 savedLegacySubmitCandidates、savedAddressCards、savedAddressTargets、savedScrollCandidates、savedConfirmationPolls。只记录标量并绑定task/attempt/device/ruleHash，不保存地址、原始树或整屏图。
+- CG109 v1现场读取未达到空闲状态，不能确认原失败具体缺哪项证据；v2覆盖迟到确认节点及可观测性，不将合成测试通过冒充真机修复验收。无Server/Web/API/迁移/权限变化，不需要服务器重启。
+
+## 探测到正式采购的单次面板交接（#262）
+
+2026-09-10 实现绑定 `2ea32fd`，Android0.9.76/code89；基于#260/#261，未声明合并main或真实采购验收通过。
+
+- AgentForegroundService通过PurchaseProbeHandoff只在成功spec_probe且结束后新快照仍识别PDD规格面板时保留一次性内存交接。仅taskId/goodsId/ruleHash/deviceId、Activity、前台revision和单调时钟时间，不保留控件节点、地址或选中状态，不落盘；有效期180秒。
+- 正式阶段消费时检查同任务/商品/规则/设备、前台revision及时间，消费后即清除。失配/超时/无任务或采集任务调度/结果异常/进程重启均不能沿用；普通手动再试不会继承已消费交接。现有服务端租约、互斥和匹配等待策略不变。
+- 有交接时，执行器恢复限定的purchaseEntryContext，最多10次、间隔200ms新读取（捕获耗时另计）；连续两次相同PDD Activity且具备既有商品/面板证据才跳过openProduct。空树可有限等待，其他应用/Activity改变/页面风险立即拒绝复用。没有交接时保留原一次判断路径；不把UNKNOWN当成功，不跳过正式精确规格/数量/价格/地址或下单验证。
+- 私有诊断新增handoffPresent、productReused布尔值，reusePolls整数及reuseReason固定枚举legacy_evidence/page_problem/page_changed/handoff_ready/evidence_timeout。仍绑定task/attempt/device/ruleHash，无敏感文本。
+- 无Server/Web、共享API或数据库变化，不需重启服务器。只有合成测试验证；原CG107/108日志证实两阶段，但未记录旧版重开判断，不把上下文丢失假设宣称为唯一现场根因。
