 - 编辑与停用采用启用状态和 version 条件更新，并与变更审计同事务提交；冲突返回 409。业务执行前先持久化请求审计意图，失败则不执行业务。完成后更新状态；更新失败或进程中断可能留下 status=0，表示结果待核对，不能据此自动重放。
 - 部分既有业务操作人字段使用该密钥最近授权管理员的 ID 兼容现有外键；实际调用方以独立审计的 key_id 为准，不能把业务字段当成人工操作证据。
 - Admin 页面 `web/src/views/goauto/client-keys/index.vue` 复用创建/编辑授权弹窗；菜单位于“采采管理”，仅管理员可见。新追加迁移 `1788798000000_client_api_key.go` 创建两表及管理员菜单，不改 Android。
+
+## 采购规格面板预滑动兼容（#238）
+
+代码基线 `58a6c1c`，Android 0.9.60 / versionCode 73（构建完成不等同于已安装/发布）。`PurchaseRehearsalExecutor.applyPostAction` 对 `openSpecPanel.swipeAfter` 只兼容解析、不执行机械预滑动，`waitAfterMs` 保留；首趟继续原 `probeSpecs` 遍历，第二趟继续原 `selectSpec` 精确查找与容器内有界滚动。其他动作的后置滑动仍沿用既有执行语义，失败不会被统一忽略。
+
+`GoAutoAccessibilityService.swipePurchase` 的失败分类由 `PurchaseSwipeFailureReason` 枚举提供；共享 `swipeNode` 仅增加可选分类回调，不改变手势目标、轨迹、1500ms 回调等待或其他调用者行为。`GoAutoPurchasePanel` 日志经 `AgentForegroundService` 关联 task、attempt、device 与规则快照哈希，新增预滑动跳过/必需滑动失败标量；不记录节点文字、坐标、原始控件树、截图或凭据。
+
+Server/Web、数据库和任务快照不变；旧 APK 仍有预滑动行为，必须更新 Agent 才生效。相关验证在 `PurchaseRehearsalExecutorTest`，Android 全量测试与 APK 构建入口不变。
+
+## SYB 逐页保存与部分成功（#239）
+
+实现绑定 c6a962d；代码已实现不代表当前线上已部署。每页完整明细在外部请求结束后按页事务保存；页回滚不累计明细/新增/覆盖数，已提交页保留。日期局部读取失败继续下一日期，全局数据库/进度/会话/取消故障停止。当天漂移不在一次运行内重扫；后续运行重新扫描并幂等补齐。
+
+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。
+
+`orderCount` 是已验证页的原始列表读取数量；`detailCount`、`created`、`updated` 为已提交明细及其新增/覆盖数量；`daysProcessed` 是完整通过的日期数，不是已尝试日期数。失败日期/页码/阶段写入现有脱敏限长 errorMessage。部分成功不刷新店铺的完整同步统计。
+
+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`。
+
+## Android 连续临时采集收尾（#250）
+
+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。
+- 验证命令：Server `go test -p 1 ./...`、`go build ./...`；Web `node --test tests/unit/syb-quick-link.test.cjs tests/unit/shopee-match-lifecycle.test.cjs`、`pnpm exec playwright test tests/e2e/syb-quick-link.spec.ts tests/e2e/shopee-match-lifecycle.spec.ts --workers=1`、受影响文件 ESLint、`pnpm build:prod`。SQLite 单连接并发测试不代替生产 MySQL 行锁验收；真实AI、生产数据、跨设备人工闭环待验证。
+
+## SYB 行内一键替换（#258）
+
+实现绑定 `2b01974`；部署与验收见 #258 发布证据。本节补充 #253，不改变原未关联入口。
+
+- `syb-products/quick-link.js` 复用分体按钮、设备偏好和匹配/回读流程；已关联且允许处理阶段时同位置显示一键替换。先只读预览，固定任务、目标商品及规格版本；不同商品一次确认，同商品不重绑。
+- `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。
+
+## 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。
+

+- 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。

+- 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。

+- 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。

+- 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。

+
+index 从 0 开始；后缀无法解析时不返回 taskId。result 为 `backfilled`、`already_backfilled`、`conflict` 或 `failed`。已认证设备所属任务可返回提交后的状态、版本、已保存订单号及时间；拒绝条目尽可能返回当前已提交事实。跨设备任务和不存在任务不返回这些业务字段，事务回滚后的内存值绝不作为最终事实返回。
+
+timeSource 说明已保存时间的来源：`page` 为页面值，`irreversible_at` 为估算回落，`existing_unknown` 为原先已创建的历史订单且没有可证明的来源。没有已保存时间时省略 timeSource。客户端必须保留估算标记，不得把回落值或 unknown 宣称为页面真实时间。重复回填不会用新页面时间自动校正旧时间。

+| `ALREADY_BACKFILLED` | already_backfilled | 正式任务已为 order_created 且订单号相同，无写入 |

+
+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。
+
+本地测试覆盖事务回滚、并发服务调用和旧写入路径，使用 SQLite；MySQL 8.4 多连接/多进程的实际行锁、生产数据和真机端到端回填尚待环境验收，不以单元测试替代。

+## 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。
+
+本节是 Admin 蝦皮详情接口补充，不修改 Android 请求或采购协议。
+
+- `GET /api/admin/v1/shopee-products/:productId` 的 `data` 增加 `autoMatchTimeoutSeconds` 整数，为后端详情一键匹配整次预算 `2 × AI timeoutSeconds + 10`，配置范围3～600对应16～1210秒。它是非敏感派生预算，沿用商品详情读取权限；不是开放 AI 管理配置读取，响应不包含 Key、Provider、BaseURL 或 Model。现有客户端路由若复用本 Handler 同样仅获得这个数字。
+- `POST /api/admin/v1/shopee-products/:productId/specs/mapping/auto-match` 请求字段、业务权限、版本核对与响应映射语义不变。服务端按收到请求时的 AI 配置确定整次父预算，读取配置耗时扣除；Provider 请求仍受自身超时及父 context 剩余时间中更短者约束。
+- Admin 点击前先GET新详情取得预算，POST timeout=(autoMatchTimeoutSeconds+10)×1000毫秒；缺字段、非整数或超范围时明确拒绝开始匹配，不猜配置。前后端需配套升级。
+- 准备后配置可能变化，浏览器仍可能先超时；不要据超时响应断言事务是否提交。POST失败/断连/超时只执行有限GET回读，不自动重发POST；失败回读显示结果未知。回读结果表示当前已保存状态，不保证这次请求已经永久不再写入，也不保证全部项目都匹配成功。
+- 普通GET默认10秒；本轮未修改建议接口610秒、其他AI功能或后台批量匹配600秒预算。T=60时130/140秒、T=180时370/380秒。
+

+
+`POST /api/admin/v1/shopee-products/{productId}/link-pdd` 新增与非零 pddProductId 互斥的可选模式：
+
+```json
+{"requestId":"UUID","latestCollection":{"sybProductId":1,"deviceId":2,"specContextVersion":"详情返回的未关联版本"}}
+```
+
+- 校验当前 SYB→Shopee、未关联、规格版本和设备存在/未停用；离线可用。短事务选择最新已结束成功或部分成功的临时采集，排序 finished_at DESC、id DESC；部分成功不跳过回退旧记录。只接受 completed、存在 finishedAt/PDD、PDD active 且存在可选颜色或尺码。
+- 成功返回原 `product`，及 `collectionSource: {taskId, deviceId, pddProductId, requiresSpecConfirmation}`。product.specContextVersion 是此次事务写入后的冻结版本；requiresSpecConfirmation 对应 failed 且没有人工或AI确认，完整资格仍由现有 batch-preview 派生。不得把后续其他人的商品版本当作本次自动匹配上下文。
+- 409 `PDD_LINK_CONFLICT` 表示已有关联；409 `LATEST_COLLECTION_UNAVAILABLE` 表示设备/最近采集/候选不可用；409 `SPEC_CONTEXT_VERSION_STALE` 沿用现有语义。非法参数422。重复请求不会覆盖已有关联，成功响应丢失后重发也会冲突，客户端应回读而非自动重试。last_update_request_id 保留本次请求标识；不承诺额外持久化完整重放响应。
+- `/api/client/v1/.../link-pdd` 带 latestCollection 时返回403 FORBIDDEN，不扩大API Key授权模块；原手动 pddProductId 模式行为不变。
+- Web 先GET详情及 #254 autoMatchTimeoutSeconds，再提交关联；关联响应中的冻结版本交给现有 auto-match。其匹配仍自动保存，无额外“保存修改”写请求。普通请求/回读每次10秒，auto-match 单独使用派生前端预算2T+20秒；业务拒绝直接提示，网络/匹配失败至多一次详情回读，再刷新准备状态，禁止自动POST重试。
+- Server/Web 需配套更新并包含 #254；无需迁移/Android升级。现有人工关联、匹配阈值、规格/采购资格、任务与支付边界不变。
+
+## Admin 一键替换最近采集候选（#258）
+
+实现绑定 `2b01974`；仅补充 Admin，Android/API Key 不变。沿用 `POST /api/admin/v1/shopee-products/{productId}/link-pdd` 和原权限，不新增路由或迁移。
+
+先请求只读预览（仍需 UUID requestId）：
+
+```json
+{"requestId":"UUID","latestCollection":{"sybProductId":1,"deviceId":2,"specContextVersion":"当前详情版本","replacement":{"preview":true,"expectedPddProductId":3}}}
+```
+
+响应 `product` 保持原关联，`collectionSource` 返回 taskId、deviceId、pddProductId、requiresSpecConfirmation，并增加 targetVersion、title、goodsId、previousTitle、previousGoodsId、deviceName。预览没有关联写入。
+
+确认提交沿用同一 SYB/设备/详情版本与原商品ID，replacement 改为：
+
+```json
+{"preview":false,"expectedPddProductId":3,"taskId":4,"targetPddProductId":5,"targetVersion":"预览返回值"}
+```
+
+- 提交按指定 taskId 核对临时采集来源、设备、completed/finishedAt、目标ID、可用规格及 targetVersion；不重新选择最新任务。旧关联、旧/目标规格版本变更返回现有409上下文冲突；阶段不再允许返回409 PDD_LINK_CONFLICT；来源不可用409 LATEST_COLLECTION_UNAVAILABLE；缺字段422。
+- 不同商品条件更新旧关联，返回更新后的 product.specContextVersion；同商品不更新关联及 last_update_request_id，但仍返回用于后续匹配的当前版本。请求不是持久化重放协议；客户端超时只回读、不自动重发。
+- 预览与提交都校验当前允许阶段；采集中拒绝。复用现有人工更换关联的映射语义，后续 auto-match 自动保存及预算沿用 #254。部分匹配/AI故障不回滚已提交关联。
+- 不提供 replacement 时 #253 行为不变；`/api/client/v1` 携带 latestCollection（包括 replacement）仍403，不扩大客户端密钥授权。
+
+## 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”。
+
+## 采购规格现场一次重新匹配（#263）
+
+2026-09-11 实现绑定 `c6ee6c0`，Server采购与Android Agent；未发布、未安装、未完成真实采购验收。
+
+- 正式采购阶段仅在服务端下发 `specRematchAllowed=true`、Android 返回稳定的 `PURCHASE_SPEC_TARGET_NOT_VISIBLE` 且尚未进入地址/下单阶段时触发；颜色/尺码选中复核失败、售罄、点击失败、歧义、价格、地址和订单错误不触发。
+- Agent 在当前PDD规格面板重新读取候选并提交同一采购任务的 `spec_rematch_completed` 结果；Server复用现有确定性优先/必要时AI匹配，结果必须属于当次候选。匹配成功后同task重新领取正式attempt，Agent沿用当前页面继续正式规格、数量、价格、地址和下单校验，不新建任务、不重新打开浏览器链接；页面证据失效时仍按原安全路径处理。
+- 每个采购任务最多一次；结果attempt和服务端状态原子记录，旧决策指针清除后只允许最新attempt固化新决策。重复请求、无资格、已有不可逆证据或旧attempt覆盖均拒绝；不新增数据库列，依赖现有attempt result_type审计。
+- 新共享字段 `specRematchAllowed` 和结果类型仅供现有Agent采购接口；旧Agent缺省false，旧 `spec_probe_completed` 重复探测拒绝规则不变。未改变设备租约、并发、支付禁止和任务重试语义。

+- 本次只完成代码构建与合成测试，未改线上配置、AI设置、常驻服务或Nginx；部署与重启需另行授权。
+- 详情匹配新窗口是后端 2T+10 秒、Web POST 2T+20 秒。当前默认API最低写超时校验仍为620秒，这是历史最低值，不保证容纳所有动态预算；发布前读取实际 AI timeoutSeconds、application.writetimeout 和生效代理配置核对。
+- 建议API写超时至少为 2T+30 秒，且仍满足原最低620秒；代理读/发送超时需留足对应窗口。T=60/180时原620秒足够容纳应用预算；T=600时至少需要1230秒API写超时及适当更长的代理窗口。不得仅设置较大的AI超时却忽略传输层更早截断。
+- 上述是发布核对要求，不是本单已修改/验证线上代理的结论。超大T带来长连接占用，不能用关闭超时来代替正确预算。新增失败回读不代表必须延长任何线上请求。
+- 必须配套发布 Server/Web；仅上新版Web连接旧Server时，因缺失派生预算会提示等待时间不可用并停止匹配。原Android不需升级。

QiuSWandClaude Opus 5	c14f5f528b	fix(server): keep agent diagnostics on order-check failures #271 normalizeOrderUnknownFailure replaced the agent's message with a canonical sentence, so the diagnostic #210 added never reached the database. Across the 61 PURCHASE_ORDER_PAYMENT_REPEATED failures on production between 2026-09-07 and 09-11, not one carried paymentBackAttempts or consecutivePaymentSamplesAfterBack, which left three very different causes indistinguishable: the Back never left the payment activity, the page rendered slower than the ~1.1s window the agent allows, or the page was already the order page and no marker matched. Those need different fixes, and there was no way to tell which one to make. The canonical sentence stays authoritative and leads the message — agent text is free-form and the wording per error code has to stay stable — but the agent evidence is now appended behind it, flattened to one line (control characters and U+FEFF removed, whitespace collapsed) and truncated to the column's 1000 runes with the canonical part kept whole. The sibling "failed" branch already stored agent text verbatim, so this adds no new trust assumption. That branch also only wrote the failure onto the task, never the attempt, so every attempt it produced carried a NULL error_code and was invisible to attempt-level statistics — the spec-panel failures on production are exactly that. It now writes both. This restores observability only; it does not reduce how often PAYMENT_REPEATED happens. Tuning the agent's sampling window is deliberately left out until the next production failure shows real values. Wiki updated first: Android-Agent-API-Contract@ba259178.

QiuSW	8293b27c19	fix(syb): retry drifting sync page once (#270 )	2026-09-12 09:34:44 +08:00
QiuSWandClaude Opus 5	c24e8a4439	docs: refresh stale wiki mirrors picked up by the same sync run Unrelated to #269. These three pages were changed online by other work and the local mirror had drifted (02 and 03 from 2026-09-10, 06 from 2026-09-04). The sync that mirrored the #269 pages regenerates every mapping, so it brought these along; they are committed separately to keep the ticket's own commit limited to its files.

QiuSWandClaude Opus 5	40a254dc41	docs: mirror SYB product filter rules and admin API #269 Wiki updated online first, then mirrored: - SYB-ERP-Interface-Contract@f1792b7f — filter order after shop admission, OR-not-AND with the 8498/6392/6386/8504 figures from the 2026-09-11 production check, empty variationSku kept, per-rule hit counts, and the no-add/no-delete rule for structural criteria. - Android-Agent-API-Contract@38869285 — the syb-product-filters endpoints, the server-side refusal of char add/delete, and the live lastHitCount requirement for the disable confirmation.

QiuSWandClaude Opus 5	503b3cbbc5	fix(goauto): create syb_product_filter on existing databases #269 Three defects that only a real MySQL run could show. The table had no version-local migration. Adding the model to migrations.Migrate covers databases built from scratch, but every existing one already has the older versions recorded in sys_migration, so that list never runs again there. cmd/migrate's post-migration table check caught it: "迁移后仍缺少表：syb_product_filter". The new version file creates the table and seeds the same eight rules with FirstOrCreate on the normalized key, so running both paths against one database cannot duplicate them. Keyword and NormalizedKeyword were typed text, which MySQL refuses to put in a key specification without a prefix length (Error 1170), so the unique index could not be built at all. They are sized 200 now, matching how SYBShop sizes its own matching key. SQLite accepts text in an index, which is why the whole test suite passed while the real migration failed. The 只看启用 filter is removed rather than kept: hiding a disabled structural rule would conceal the one state on this page that matters most, since a disabled "#" means roughly 65% of 档口 rows start entering the system again. Keyword search stays. Verified against the local MySQL database: migration applies, eight rules present with traditional Chinese preserved (印花大學T normalizes to 印花大學t), menu row created under 采采管理.

QiuSWandClaude Opus 5	cad9f6d185	fix(goauto): add the missing menu migration for SYB product filters #269 Registering a module in access.GoAutoModules() does not make its page reachable on an existing database. sys_menu rows are written by the versioned migration that first created them, and that version is already recorded in sys_migration everywhere — it never runs again. Startup only reconciles the casbin API matrix, not menus. So on a fresh database the page appeared and on every real one it did not: the table, the API and the route were all present with no way to navigate there. This adds a migration that upserts the entry under 采采管理 beside 「SYB 店铺」 and binds it to both 管理员 and 采购员. Verified by deleting the row from an already-migrated database and re-running migrate: 新执行 1 个，跳过 42 个, row restored with both roles.

QiuSWandClaude Opus 5	78df997fc3	test(goauto): pin SYB filter behaviour against real variationSku samples #269 The samples are the ones the production database actually holds: 档口 codes like "新寮-雅伊阁大码女装#301" and "DD#004" must be filtered, while own codes like "PDD0582", "my238", "1" and "引流款" must not, and an empty variationSku is a product without a supplier code rather than a 档口 item. The test also asserts the two structural rules record different hit counts. That is the property the previous aggregate-per-kind write could not hold, and the disable-confirmation dialog depends on it.

QiuSWandClaude Opus 5	20f59b68bd	fix(goauto): record SYB filter hits per rule, not per kind #269 UpdateHits wrote one aggregate per kind, so every structural rule stored the same number. The disable-confirmation dialog quotes that number ("停用「#」后…约 N 条明细会恢复入库"), and on real data "#" matches 8498 rows while "-" matches 6392 — the dialog would have warned with a figure 2100 rows off for one of them. Match now returns the rule that matched instead of a char/keyword pair, so the caller can attribute each hit to one rule, and UpdateHits writes every rule's own count. Rules that matched nothing are written as 0 so a previous run's number is never left behind. The management page is reformatted to the repo's usual Vue layout and gains the search / 只看启用 / 重置 controls the approved prototype shows. Cancelling the disable confirmation now just reverts the switch instead of throwing an unhandled rejection.
