+
+同步状态增加 `partial_success`（部分成功，15 字符，复用现有 varchar(16)，无需迁移）。有错误且 created+updated>0 为部分成功；有错误无已提交明细为 failed；完整且无错误为 succeeded（包括无符合店铺的数据）。中断仍为 interrupted，不把中断追认为成功。所有终态沿用活动槽释放规则。

+
+Web 唯一展示位置为“采集采购 → SYB 同步记录”：列表状态、状态筛选及详情支持部分成功，详情保留已保存数量、错误原因与重新同步补齐提示。定时任务日志只表示异步任务受理，不等于最终业务同步成功。
+
+入口为 `SyncWithShopSnapshot → loadDailyList → importSyncPage`；`server/app/goauto/sybimport/sync_page.go` 封装页事务和提交后计数；`import_handler.go` 判定终态，`sync_run.go` 保存及筛选，Web 复用 `web/src/views/goauto/syb-sync-runs/index.vue`。

+当前实现绑定 `37e8b56`（Agent 0.9.72 / 85），用户确认 v5 按次数返回后切回 Agent。仅 Android，无 Admin/API/权限/数据库迁移；取代 v1～v4 首页导航。
+
+- `AgentSettingsFragment` 在采集间隔后复用卡片和 SwitchMaterial；仅开启显示“返回次数”按钮，Material 单选框选择 1～5 次（默认 3），立即保存或取消。成功无常驻反馈，错误/忙碌显示原因。任务忙碌禁用，弹窗选定时再检查。
+- `AgentSettingsStore` 在私有 `goauto_agent_settings` 保存 `continuous_collection`（false）与 `continuous_collection_return_count`（3）；次数越界或读取错误回落 3，写入失败恢复旧值，无网络加载。
+- `requestCurrentPageCollection` 保留原范围判断；`executeTask` 在采集开始固定次数。`executeTaskWhileAwake` 提交结果、结束图片上传后返回 resultStatus；`ContinuousCollectionPolicy.finish` 仅对完整确认成功调用新 `PddCollectionReturnNavigator`。失败/部分成功不导航。冷却间隔不变，连续模式不启动旧 idle-return。
+- 删除 `PddCollectionHomeNavigator` 和专属首页/搜索层判据。新导航器仅使用 capture/back、当前包名、openAgentPreservingTab；1～5 次 Back，每次后 500ms，前台离开 PDD 终止剩余 Back；保留风险场景停止。最后打开 Agent 并等待 500ms 验证包名，不验证 PDD 首页。仍在原任务互斥与唤醒锁范围内完成，结束后原 finally 释放。
+- `GoAutoCollector` 日志关联 taskId、attemptNumber、deviceId、规则快照 SHA-256；记录 continuousReturn、configuredBacks、固定 reason 和 actions。原因含 count_completed、left_pdd、back_failed、unsafe_page、agent_launch_failed、agent_not_confirmed、navigation_exception、invalid_count；actions 为 Back 尝试数，不代表最终页面。无节点文字、树、截图或个人数据落盘；不扩大采购诊断存储。
+- `ContinuousCollectionTest` 覆盖范围/终态、1～5 次、无变化仍按次数、前台变化、风险、动作/启动失败、包名确认和异常；`ContinuousCollectionSettingsTest` 覆盖开关与次数持久化、默认/越界/写入失败。`:app:testDebugUnitTest :app:assembleDebug` 376 项通过。旧首页专属测试随旧行为替换，新版未安装，UI 大字体/横屏、多设备和完整采集真机链路尚未验证。
+
+## SYB 存疑规格候选解析（#251）
+
+实现绑定 `64b4205`，仅 Server `app/goauto/sybimport`；无 API 字段、数据库迁移、权限、并发模式或 UI 变化。
+
+- `parse_candidates.go: ParseWithCandidates` 先运行原 `Parse`，仅 uncertain 时解码并校验已存 SpecsJSON；复用 `closedShopeeCandidates` 提取颜色/尺码封闭候选，拒绝未知有值角色/重复角色。完整候选组合与原文归一比较唯一时确认，其他情况返回原 ParseResult。
+- `ApplyDetail` 在加载既有蝦皮商品后、写入规格前调用；`Reparse` 在保留人工/AI 确认保护后加载关联候选调用。新增 ParseResult 私有 matchedCandidates 标记，使 `mergeParsedSpec` 对已经存在的候选直接返回，避免按维度名重复合并或改变映射。
+- #198 `ProcessSpecAIParseRun → Reparse` 自然接入确定性优化，仍需 AI 的记录沿用原后续步骤，不新增异步任务/Provider 调用/接口。
+- 验证 `go test ./app/goauto/sybimport ./app/goauto/aimatching ./app/goauto/shopeeproduct ./app/goauto/purchase` 和 `go build ./...` 通过；新增候选正反/格式/组合色/单维度、歧义/空值、同步重解析一致、人工保护及无需调用 AI 测试。AI 原有置信度/失败重试测试改用仍需语义理解的合成输入，继续验证原分支。
+- 本轮只使用本地测试数据与 httptest AI，未触发真实 SYB 同步、外部 AI、采购、数据库迁移或服务重启；线上及历史数据效果尚待授权验证。
+
+
+## 蝦皮详情匹配等待与回读（#254）
+
+实现绑定 `9088e6b`（2026-09-10，分支 fix/254-match-loading）；已通过合成数据测试，尚未合并 main 或发布线上。
+
+- Server `shopeeproduct.Service.DetailWithAutoMatchBudget` 为详情 GET 附加派生的整次匹配预算，不返回 Provider、Key 等配置。`AutoMatchMappings` 读取 AI 设置 T，使用 2T+10 秒的单个父 context；颜色、尺码、保存及结果回读共用剩余时间。初始配置读取也受有界 context 约束，读取耗时从后续预算扣除。
+- 批量定时匹配调用内部 `autoMatchMappings` 并继续使用原 MaxProviderTimeout=600 秒，不随本次详情入口调整；候选建议与其他 AI 功能不改。
+- Web `ShopeeProductDetailDrawer` 在提交前以普通 GET 刷新商品与预算，仅 auto-match POST 使用 (2T+20) 秒超时。准备失败/缺少预算时不发 POST；旧 Server 必须先更新，不能只发布新版 Web。
+- 加载状态同时绑定商品加载代次和操作序号。关闭/切换立即结束该页面等待状态；同商品重开读取详情，旧响应/旧 finally 不得污染新操作。匹配期间禁止在当前抽屉编辑映射，原人工草稿放弃确认保留。
+- POST 未正常返回时只回读详情及关联 PDD，不自动重发 POST；回读失败结束转圈并保留刷新入口。GET 沿用单请求10秒超时，完整结果回读最多两次串行 GET，不是无限等待。
+- 验证：Go shopeeproduct/aimatching/clientapi 测试与 go build；Web `node --test tests/unit/shopee-match-lifecycle.test.cjs`，Playwright shopee-match-lifecycle 与 shopee-pdd-picker，受影响 ESLint 与 build:prod。
+
+
+## SYB 行内一键关联最近采集（#253）
+
+实现绑定 `b1594dc`，2026-09-10；分支 feat/253-one-click-link，包含 #254 依赖。已完成合成数据测试及构建，未合并 main、未部署，不代表当前线上已具备此能力。
+
+- Web `syb-products/index.vue` 在“去关联”旁增加“一键关联＋下拉箭头”，共享 `quick-link.js` 页面级状态。`quick-link-device-preference.js` 按当前浏览器来源、API环境、用户ID保存设备ID，独立于批量采购偏好；不存密钥或商品数据。首次主动作选机继续原行，箭头选机只保存偏好。
+- Server `shopeeproduct/latest_collection.go` 复用 LinkPDD 的可选 Admin 模式。短事务核对 SYB→Shopee、未关联/规格版本、设备状态，选择并锁定最新 completed/completed_partial 的 agent_current_page 任务及其 PDD；仅完整采集、active且有可用颜色或尺码时更新，WHERE pdd_product_id IS NULL 不覆盖其他操作者的关联。响应保留该事务产生的规格版本及来源task/device/PDD，不能用后续GET替换冻结上下文再自动匹配。
+- 不新增表、迁移、路由或权限对账。原手动关联/替换请求不变；共享 Handler 明确拒绝 Client API 使用此跨模块模式，不能借 Shopee-only write grant 读取 SYB/设备上下文。来源任务原规则快照不改，taskId 可回溯既有采集证据。
+- 关联后读取现有采购准备；需要人工确认或不具备AI资格时停止自动链路并保留关联，其他情况调用原 AutoMatchMappings，沿用 #254 动态预算及原事务保存/上下文冲突保护。最后刷新实际处理阶段，不调用创建采购/订单接口。
+- 运行期间冻结行、商品、手机；前端重复主动作禁用，切换偏好仍只影响未来操作。卸载或 keep-alive deactivated 令旧操作失效，禁止旧回调继续下一步；不声称已经取消服务端在途写入。异常仅有限GET回读和刷新，不自动重发POST。

+- `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。

+- 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。

+- 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。

+- 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。
+- 每次 Back 前检查前台仍为 PDD，读取页面后再次检查；离开 PDD 则停止余下 Back。次数完成、离开 PDD 或 Back 动作失败后，尝试打开 Agent 保持原 Tab，等待 500ms 并验证前台包名。动作失败不重试，不把请求启动成功直接当作切回成功。
+- 沿用风险页安全边界：登录/验证码/风控、地址编辑、订单详情或支付等证据时保留现场，不发送 Back 或强行切回；Activity 缺失、读取异常明确停止。以上例外不引入首页门禁。
+- 导航在原任务互斥和唤醒锁内完成，不变更租约/调度。返回失败只显示人工处理提示，不把成功采集改为失败或自动重采。
+- 失败、部分成功、提交未确认保留现场，不运行返回步骤，也不触发旧空闲返回倒计时。关闭开关保持原流程，采集间隔不变。
+- 不自动拍照、搜索或创建下一任务，不涉及采购/订单/付款；不使用深链、浏览器、OCR/VLM 或坐标兜底。
+
+## SYB 存疑规格候选核对（#251）
+
+实现绑定 `64b4205`，基线 main `fdd26af`；2026-09-09 代码与本地测试/构建通过，未部署、未重跑生产历史数据。
+
+- 原 Parse 的成功与失败行为不变，仅 uncertain 明细增加既有蝦皮规格候选核对。比较完整原文，沿用【备注】清理，允许全角逗号、逗号两侧空白及连续空白归一；颜色尺码可正序或倒序，使用逗号或空白分隔，只有唯一完整组合才改为 success。返回既有候选标签，不改写标签，不删除加号、不截断体重说明、不做近似匹配。
+- 单规格只有在候选确实仅包含该角色时通过；有两个角色时不能用单值补猜另一个角色。空/损坏候选、校验不通过、同角色多维、未知有值维度、多种组合或归一化碰撞，均保留原结果。候选必须已存在，不能用本次待确认输入生成候选再自我证明。
+- 同步入库 ApplyDetail、手动 Reparse 共用；成功核对不再次合并规格，因此不新增重复维度、不覆盖已有映射。人工确认仍优先，默认 Reparse 跳过人工与 AI 已确认值；原文保留。
+- #198 批处理原本先 Reparse，所以可直接复用本优化：能确定的不用调用 AI；仍不确定的按原 AI 流程处理。没有新增调度、调用额度或同步等待，不自动开启已有任务。
+- 不取消 uncertain/failed 状态，不改变采购可信度/可采购规则，不实现一键关联 PDD。部署后新同步或显式重新解析会使用新逻辑；本次没有执行生产批量更新。
+
+
+## 蝦皮详情匹配等待与回读（#254）
+
+实现绑定 `9088e6b`（2026-09-10，分支 fix/254-match-loading）；已通过合成数据测试，尚未合并 main 或发布线上。
+
+- AI 设置中的 timeoutSeconds=T 仍是单次 Provider 请求的上限。详情一键匹配的整次预算为 2T+10 秒，浏览器 POST 等待上限为 2T+20 秒；例如 T=60 时130/140秒，T=180时370/380秒。只保留现有一个 AI 设置入口，不新增时间配置框，也不自动改变管理员已保存的 T。
+- 超时上限不是固定等待。颜色/尺码串行执行且共用整次预算；正常部分匹配仍按原事务保存合格结果，AI异常在保存前返回时不提交本轮新映射。既有置信度、候选、人工确认映射保护和采购资格不变。
+- 前端超时、关闭或切换详情不代表后端已取消、未保存或已回滚；必须以回读结果为准，无法回读显示结果未确认，不自动重复匹配、不自动创建采购。
+- 单商品详情的成功/失败/超时/关闭重开都必须结束失效的等待状态；旧请求不得覆盖新商品或新操作。匹配进行期间本抽屉不能人工改映射，已有未保存草稿仍按原确认流程处理。
+- UI匹配提示的等待上限仅指POST，不含提交前GET及结果核对GET；结果核对也有限时，不能让失败提示再次陷入无限转圈。
+
+
+## SYB 行内一键关联最近采集（#253）
+
+实现绑定 `b1594dc`，2026-09-10；分支 feat/253-one-click-link，包含 #254 依赖。已完成合成数据测试及构建，未合并 main、未部署，不代表当前线上已具备此能力。
+
+- 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。

+
+复用现有单线程诊断队列异步写入，写入/排队失败不改变采购结果；不新增点击、滑动、等待或采购门禁。最多保留最近 5 个 attempt 文件、每文件最后 128 条事件，超过 7 天的文件在服务启动或下次写入时清理。异常断电或存储故障仍可能丢失诊断，不能将日志缺失当成动作未执行；不上传 Admin，不增加服务端接口。
