+
+GoAuto 默认采用轻量治理。文案、注释、格式、局部样式或布局、预期行为明确的小 Bug，以及不改变接口、数据结构、权限和安全边界的单模块低风险调整可以直接实施，无需为了留痕补建工单。完整独立需求、新页面、跨模块功能，以及 API、数据结构、权限、安全、迁移或范围不明确的变化必须建单。
+
+采购、创建订单、真实个人或生产数据、权限、安全、并发、数据库迁移、删除数据、发布和其他不可逆操作始终升级为高风险。无论任务采用何种最小门禁，凭据保护、永久禁止付款、个人与生产数据最小化、设备互斥、Agent 禁止 OCR/VLM、控件树与整屏截图禁存、工作区保护、真实测试和人工验收均不可裁剪。
+
+### 明确授权后的执行
+
+- 当前聊天中用户给出的明确指令，或 Gitea 工单中能够归属于有权人工的明确授权，可以作为执行依据，不要求把同一授权重复复制到工单后再次确认。
+- 授权必须能识别操作、对象和范围；Agent 自动生成的工单、草稿、摘要或对用户意图的转述不能单独构成人工授权。
+- 获得有效授权后，只核对准确目标、授权范围和当前状态等最小必要前提，不得仅因操作不可逆而重复询问或拒绝。
+- 授权不自动覆盖相邻对象或后续任务；环境、对象、范围或影响发生实质变化时重新确认。平台自身强制的审批、安全策略或权限限制继续有效。
+
 ## 工单与设计证据双门禁
 
 正式实施前先判断是否需要工单，再判断需要什么设计证据。工单不能替代原型确认，原型也不能替代技术方案、安全检查和单元工单。

+- 版本迁移会对历史存活店铺回填 `normalized_name = Normalize(display_name)`；回填只改匹配键且可重复执行。若两个存活店铺回填后会得到同一键，迁移必须整体失败并保留原数据，管理员先人工消除歧义后再执行，不能静默合并、删除或改变店铺启用状态。
 - 店铺可以从 SYB 真实货运单列表发现，也允许管理员手工补充。只有管理员可以新增、改名、启停和软删除，采购员等其他角色只读。
 - 没有任何启用店铺时，导入必须在读取凭据、建立会话、验证码 OCR 和任意 SYB 网络请求之前失败，并给出“请先启用店铺”的可读提示。
-- 同步必须先拉取并校验当天原始全量列表的总数、分页和唯一 ID，再按本次同步开始时固定的启用店铺快照过滤；过滤不能降低完整性校验的请求范围或容量上限。
+- 同步先预检全范围总数及上限，每页校验原始列表条数、合法 ID 和重复，再按冻结店铺快照获取明细并页事务保存；整日结束核对总数。过滤不能降低完整性校验范围，已保存不能冒充整日完整（#239，c6a962d，待部署版本）。

+## 设备身份恢复
+
+- 管理员可在设备管理对未停用设备发起“重置设备身份”。此动作不删除设备记录、不改变设备 ID、能力或已绑定的待领取任务；它立即使旧 Token 无效，并只生成一次、有效期 10 分钟的恢复码。
+- 恢复码仅显示给发起操作的管理员一次，服务端只保存摘要；不得进入列表、日志、任务记录、Android 持久化或普通接口。手机操作员必须在同一安装实例的 Agent 设置中手动输入。
+- 服务端只接受同一 `installId`、未过期且尚未使用的恢复码完成重新注册，成功后签发新 Token 并使恢复码失效。过期、重复使用、installId 不符或停用均明确失败；不能通过清空数据、直接改库或“吊销 Token”恢复原任务归属。
+
+- 自 #223 起，任务创建时把与冻结 SYB 目标对应的已确认商品规格映射保存为不可变的探测指导快照，但仍不得跳过首趟真机探测。探测完成后，每个角色先验证快照映射能否按既有规范化规则唯一对应当次候选，能对应时固化当次候选原文；不能对应时只对该未解决角色执行确定性匹配，仍无结果才调用 AI。已解决角色不重复交给 AI，任一最终值仍必须逐字属于当次候选；历史映射失效、规范化后歧义或角色不符时不得复用。候选完整但无法决策时提示“已采集到当前规格，但未能确定颜色或尺码映射”，不再误报候选不存在。
+
+## 采购商品深链入口（#232）
+
+- Android 采购新任务（含探测与人工重试）打开商品时，优先使用指定 PDD 包名的 ACTION_VIEW，并设置 NEW_TASK 与 CLEAR_TASK，以清理旧任务栈后交付该任务链接。清理的是 Activity 返回历史，不是清除应用数据或强制停止进程。
+- 直接启动失败（包括无可处理 Activity）时回退既有浏览器入口；启动请求被接受后仍由执行器验证稳定商品页面，停留首页不会仅因启动成功而判定完成。
+- 清栈不用于改地址后返回、下单后回到 PDD、订单核查；采集入口继续使用既有浏览器流程，避免绕过规则中的浏览器步骤。
+- 当前通用商品页面结构验证不能独立证明页面 goods_id；解析结果携带的任务 goodsId 不是页面回读证据。首次直接深链上线仍需以实际目标商品真机核对，ADB 实验不替代 Agent 上下文验证。
+## SYB 批量采购设备偏好（#233）
+
+- SYB 商品页“批量创建采购任务”按当前登录用户 ID、当前浏览器来源与 API 环境记住最近一次设备选择；主动清空也记忆为不指定设备。只保存设备 ID，不保存 Token、账号凭据或订单信息。
+- 弹窗打开后先按现有在线/可选/采购能力条件加载设备，再恢复选择并以相同设备预检。记忆设备当前不可用时保留偏好并提示用户重新选择或明确清空，不静默切换设备或自动领取。
+- 预检加载中、失败或记忆设备不可用时不能提交；过期预检结果不覆盖新的设备选择。服务端原有设备及采购资格校验不变。

+
+- 仅管理员创建、查看、编辑授权或停用密钥。首版不提供密钥改名、到期、轮换、恢复启用、删除或任意接口授权。
+- 模块选择复用“采集采购/采采管理”现有 12 个业务模块；分组勾选只影响当前子模块，新菜单不会自动获得授权。客户端密钥管理、系统账号权限及支付不在可授权模块中。
+- 勾选模块默认只读，至少保留一个模块。读写仅开放清单中的普通写操作；同步、采集、采购、删除、导入、重解析、匹配、回写及切换当前采购规则分别独立授权，默认关闭。没有普通写接口的模块不允许勾选读写。
+- 编辑既有密钥不会更换密钥，名称和前缀只读；移除模块同时移除其动作。取消保留原授权；失败保留输入；版本冲突要求刷新重开。停用不可编辑或恢复。
+- 保存后新请求按最新授权校验，已经通过校验的在途请求可能完成，不追溯回滚。模块授权不是行级、店铺级或租户隔离，授予读取即允许读取该模块明确接口可返回的业务范围。
+- 用户于 2026-09-07 明确接受明文风险：密钥管理及客户端接口默认兼容 HTTP/HTTPS，无需开关。HTTP 会明文传输密钥与业务数据，建议优先使用 HTTPS；兼容不改变管理员身份与模块授权边界。
+- 客户端与 Admin 登录 JWT、Agent Device Token 独立。响应排除凭据及原始载荷字段；AI 设置只返回 enabled，不开放 Provider 配置读写或连接测试。设备仅开放列表，不开放身份重置、令牌或解锁接口。
+- 执行动作复用既有业务门禁、幂等参数及状态机；客户端采购 batch-retry 沿用 Admin 原有语义，不等同于 Agent 就地 reset。授权重采购、支付复核、取消订单等未列入接口不开放；永久禁止付款。
+- 创建响应丢失时不可找回完整密钥，应核对列表并停用可能已创建的记录，再明确创建新密钥，不能盲目自动重试。完整密钥只在创建结果弹窗内存中显示，关闭或离开页面清空，不写浏览器持久存储。
+
+## 打开采购规格面板后按需滚动（#238）
+
+- Android 0.9.60 / versionCode 73，代码 `58a6c1c` 起，规则 `openSpecPanel.swipeAfter` 保留格式校验与旧快照兼容，但不执行打开面板后的固定次数预滑动；不以“必须滑两次成功”作为进入规格探测/选择的条件。动作后的 `waitAfterMs` 仍生效。
+- 首趟规格探测和第二趟精确选择仍使用各自既有的按需横向/纵向、有界与稳定终止策略。取消预滑动不等于不探测隐藏规格，也不等于只看首屏。目标不存在、歧义、页面证据不足或必要的有界查找失败时仍明确失败。
+- 此调整覆盖所有已经安全识别打开的面板，不再仅特判 NON_SCROLLABLE_CONFIRMATION；不弱化面板验证、精确选中、地址、价格、任务租约、创建订单边界或禁止支付规则。
+- 其他动作的后置滑动沿用原行为，必需滑动失败仍返回 RULE_ACTION_FAILED。旧规则 JSON 不回写、不迁移；原任务 ID、历史 attempt、商品与规格快照不变。旧 APK 行为不变，需升级 Agent；本单未改线上规则或执行 CG68 真机采购。
+
+## 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。

-创建阶段需要外部 AI 的任务会先以 `pending` 与持久匹配工作项同事务创建并立即返回 Admin。工作项处于 `pending`、`running`、`retry_wait` 或 `manual_required` 时，`next` 不返回该任务，直接调用 `claim` 或 `start` 也会返回状态冲突。匹配完成后 Agent 仍只接收服务端固化的精确 PDD 原始标签；Android 接口和请求体不新增 AI、候选或人工决策字段。
+自 #215 起，新建 SYB 采购任务不再从 PDD 档案创建持久匹配工作项，也不在首次派发前调用外部 AI；部署前已存在的 `purchase_spec_match_work_item` 继续按原状态兼容处理。新任务首次 `start` 固定得到 `phase=spec_probe`，Android 通过浏览器打开任务链接一次并经既有结果字段回传当次候选；匹配成功后的第二次 `start` 才得到 `phase=purchase` 和服务端固化的精确 PDD 原始标签。连续第二阶段仅在当前 PDD 页面仍有商品页或规格面板强证据时复用首趟页面、不再次打开浏览器链接；手动同任务重试，或当前为 Agent、其他应用及缺少上述强证据时，Android 重新打开任务 `urlSnapshot`。两种路径都不以标题、goodsId 或页面指纹做严格同页校验，仍必须通过 PDD 包名和商品/规格/订单页面结构安全证据。Android 不接收 AI 配置或自由决策权限。

+任务 payload 的必传布尔字段 `specResolutionAllowed` 是 Android 是否可以提交规格探测的唯一资格事实。新建 `taskType=syb_order` 任务必须由声明 `purchase.spec-probe.v1` 的规则创建，初始 `SpecDecisionRequestID` 为空且 `specSource=unresolved`，首趟返回 `true`；当次决策固化后返回 `false`。`stock`、`direct_select`、已固化规格决策、能力缺失及其他组合均返回 `false`。普通 Agent 重试使用就地 `/reset`，保留 `SpecDecisionRequestID`、目标规格、映射规格和规格决策快照，不能恢复探测资格；映射不完整时必须拒绝，不能进入正式采购阶段。只有替代商品“继续采购”或 Admin 批量重试创建的新任务才按 #215 重新取得一次探测资格。Android 不得根据映射是否非空、错误文字或本地判断扩大资格。
 
 Android 规格失败使用五个稳定阶段：`PURCHASE_SPEC_TARGET_NOT_VISIBLE`、`PURCHASE_SPEC_TARGET_AMBIGUOUS`、`PURCHASE_SPEC_SAFE_TARGET_MISSING`、`PURCHASE_SPEC_CLICK_FAILED` 和 `PURCHASE_SPEC_SELECTION_UNCONFIRMED`。`PURCHASE_SPEC_CLICK_FAILED` 的 `errorMessage` 只允许稳定子原因 `root_unavailable`、`target_stale`、`no_clickable_ancestor`、`action_click_false` 或 `unknown`；其他阶段的消息不得包含规格原文、坐标、控件树或截图。只有 `PURCHASE_SPEC_TARGET_NOT_VISIBLE && specResolutionAllowed=true` 可以提交规格探测，其他四态直接提交真实失败，服务端原样保留稳定阶段/子原因。旧 Agent 在资格已用尽后再次提交 `spec_probe_completed` 时，服务端以 `PURCHASE_SPEC_REPROBE_REJECTED` fail-closed，释放租约并保留第一次规格决策，不再冒充新的选择根因或再次派发。无匹配、候选不完整、歧义或 Provider 异常同样使任务失败。`order_result_unknown` 只允许管理员或采购员人工解除，永不自动重派。

+
+规格探测与精确选择自行负责按需有界滚动，原始候选、精确点击和选中复核不变。跳过预滑动不作为规格探测成功或订单创建证据。
+
+本地 `GoAutoPurchasePanel` 脱敏结构日志关联 task、attempt、device、rule（规则 SHA-256），不上传原始页面。新增事件：`postSwipe=skipped;action=openSpecPanel;reason=spec_panel_on_demand;panel=<枚举>`；其他必需滑动失败为 `postSwipe=failed;action=<动作枚举>;direction=<方向枚举>;swipeIndex=<本动作内第几次滑动>;reason=<固定分类>`。
+固定失败分类：unknown、root_unavailable、no_scrollable、invalid_bounds、gesture_unsupported、gesture_rejected、gesture_cancelled、gesture_timeout。日志不含规格值、节点文本、坐标、地址、订单、凭据、原始树或截图；结果错误码仍为 RULE_ACTION_FAILED，现有结果提交字段不变。
+
+## 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。

+### API 长请求超时约束
+
+Admin 蝦皮规格 AI 匹配会同步等待外部 Provider：Provider 配置允许 3～600 秒，复合的一键匹配共享 600 秒总预算，Admin 客户端等待 610 秒。因此服务端 `settings.application.writetimeout` 必须至少为 620 秒，受版本管理的标准配置固定为 `620`；启动时低于该值必须明确失败，禁止以 2 秒等短写超时运行，否则连接会在领域错误返回前被截断并表现为代理 502。反向代理的读/发送超时也必须大于服务端窗口。
+
+Provider 故障日志只允许记录调用关联 ID、操作类型、耗时、上游 HTTP 状态码或网络错误分类；不得记录 API Key、Authorization、Provider URL、模型输入、候选规格、商品原始内容或响应正文。Provider 失败时接口返回 HTTP 503 与 `AI_MATCHING_UNAVAILABLE`，供 Admin 显示安全中文提示。
+
 ## 回滚
 
 服务异常时把 `/home/goauto/current` 切回上一已验证发布目录并重启 `goauto.service`，随后复核服务状态和 Agent 接口。不要删除当前或历史 APK/发布目录来代替回滚；数据库变化如需回退必须单独评估。
+
+## 蝦皮规格自动匹配任务运维（#195）
+
+- 迁移 `1788290000000_shopee_spec_auto_match.go` 创建运行与工作状态表，并幂等写入 `sys_job.invoke_target=GoAutoShopeeSpecAutoMatch`。首次部署状态为关闭，迁移重跑不会覆盖管理员后来修改的 Cron、参数或启停状态。
+- 默认 Cron 为 `0 15 * * * *`（每小时第 15 分钟），默认 `batchLimit` 为 20，合法范围 1～100。上线后先保持关闭，在 Admin 蝦皮商品列表手动执行小批次并核对运行摘要和映射，再由管理员在定时任务页明确启用。
+- 定时和手动触发共享数据库唯一活动槽。看到“已有自动匹配正在运行”属于正常互斥结果；运行租约超过 30 分钟会在下次触发时安全释放并把旧运行标记失败。处理每个商品前会续租。
+- Provider 临时失败的商品至少 60 分钟后重试，最多 3 次；低置信度或无结果在输入指纹不变时不会重复调用。排错优先查看 `shopee_spec_auto_match_run` 的结构化计数与脱敏错误，以及 `shopee_spec_auto_match_work_item` 的状态、尝试次数、下次尝试时间和租约；不得输出或复制 API Key、Provider 原始响应、商品原始 JSON 或个人数据。
+- 紧急回退只需关闭系统任务并停止使用 Admin 手动入口；保留运行记录和既有已确认映射用于审计，不删除数据，也不回滚 #194。
+
+## SYB 异常规格 AI 定时任务（#198）
+
+- 追加迁移 `1788354164329_syb_spec_ai_parse.go` 创建 AI 确认字段、`syb_spec_ai_parse_run`、`syb_spec_ai_parse_work_item`，并幂等写入 `sys_job.invoke_target=GoAutoSYBSpecAIParse`。
+- 系统任务默认关闭，默认 Cron 为每小时第 5 分钟、参数 `{"batchLimit":20}`；迁移重跑不得覆盖管理员后续修改的 Cron、参数或启停状态。建议先运行该任务，再由默认第 15 分钟的 #195 完成蝦皮到 PDD 的规格匹配。
+- 多实例通过可空唯一活动槽和租约保证全局单批运行；逐行工作项按输入指纹去重。Provider 临时失败至少 60 分钟后重试且最多 3 次，低置信度/无结果在输入不变时不重复调用。
+- 上线顺序为：备份数据库、执行追加迁移、发布服务并保持任务关闭、核验表/字段/任务种子，再由管理员决定是否启用。排错只查看运行计数、工作状态和脱敏错误，不输出 API Key、Provider 原始响应、完整 RawJSON 或订单数据。
+
+## 定时任务执行历史运维（#199）
+
+- 发布 #199 时先备份数据库，再执行追加迁移 `1788357000000_sys_job_execution_log.go`，随后发布服务与 Web。迁移创建 `sys_job_execution_log`、登记 `GET /api/v1/sysjob/:id/execution-logs`，并只为原本绑定隐藏菜单 `JobLog` 的角色写入精确读取权限；菜单缺失时迁移明确失败，不扩大角色授权。
+- 服务启动会将上次进程遗留的 `running` 执行记录标记为 `interrupted`。该恢复依赖当前线上每个数据库只运行一个调度器实例；扩展为多调度器前必须另建工单引入实例租约，不能直接复用此判断。
+- 排错从 Admin 定时任务页单选任务后进入“日志”，按状态和开始时间查询。记录只含稳定错误码和脱敏摘要；需要定位细节时查看受控服务日志，不得把任务参数、Provider 配置/响应、密钥或业务原始数据复制进执行历史。
+- 当前没有执行历史删除接口和自动保留策略；删除定时任务不删除历史。数据库容量治理需要另建工单评估。#198 的 `GoAutoSYBSpecAIParse` 在 #199 发布和迁移后仍保持关闭，启用必须由管理员另行确认。

+实现基线 `71f7751`；2026-09-07 已按用户授权完成本机 MySQL 迁移、管理员菜单写入和 Server/Web 构建重启；管理页面 HTTP 列表与模块加载已验证。线上仍未部署。
+
+- 发布前须单独授权追加迁移 `server/cmd/migrate/migration/version-local/1788798000000_client_api_key.go`，按既有迁移流程创建 client_api_key、client_api_key_audit 和“采采管理/客户端密钥”管理员菜单。前置父菜单必须存在；不应以赋予普通用户管理员角色代替迁移或权限核验。
+- 用户于 2026-09-07 明确确认默认兼容 HTTP/HTTPS、不设开关并接受明文风险；部署本版本并执行迁移后，现有 `http://185.216.248.75:9527` 可以使用客户端密钥管理及客户端 API。本机已部署验证，不能据此宣称线上已经可用。HTTP 会明文传输密钥和业务数据，仍建议使用 HTTPS。
+- 客户端密钥功能不依赖 GOAUTO_TRUST_FORWARDED_PROTO、X-Forwarded-Proto 或 Agent HTTP 例外。既有其他路由的协议和代理配置保持不变；不伪造协议头，不新增明文放行开关。
+- 代理、APM、应用日志均不得记录 Authorization、创建响应 secret 或原始业务载荷。应用对两类客户端密钥路由跳过旧请求/响应正文日志，使用专用元数据审计；实际代理日志脱敏仍须部署验收。
+- 请求审计 status=0 可能表示在途、进程中断或结果审计更新失败；先按请求关联号核对业务结果，不自动重试采购、采集、同步等操作。停用阻止后续认证，不保证取消已开始的业务操作。
+- 隔离验证：Server `go test ./app/goauto/clientkey ./app/goauto/clientapi ./cmd/migrate/migration/version-local`；Web `pnpm exec jest tests/unit/client-keys.spec.js --runInBand` 与 `pnpm run build:prod`。浏览器模拟入口 `/tests/fixtures/client-keys.html` 仅由本地 Vite 开发服务承载，使用内存模拟请求和无效示例密钥，不连接真实数据库，不证明线上鉴权已验收。
+- 真实部署验收须另行验证实际 HTTP/HTTPS 入口、管理员创建/编辑/停用、普通用户拒绝、读写/独立动作隔离、停用后的后续请求拒绝及日志无密钥；任何真实业务执行继续按独立授权范围进行。

+- 真实迁移必须单独授权并先确认唯一待执行版本；常驻 API 加 `-SkipMigration`，日常重启不自动执行未来待审核迁移。#237 迁移 `1788798000000_client_api_key.go` 已执行，sys_migration 记录 `1788798000000`、两张密钥表及管理员菜单已回读；其他角色未新增菜单关联。任务启停状态未改。
+- 范围明确的服务控制：`D:/supervisor/supervisord.exe -c D:/supervisor/supervisord.conf ctl status goauto-admin-api goauto-admin-ui`，启动/停止/重启将 status 分别替换为 start/stop/restart。不得为了 GoAuto 重启整个 Supervisor 或其他项目。配置内容变化后需重新读取配置；本次调用 `supervisor.reloadConfig`，再对上述两个程序定向 start，已通过进程命令行核对新目录。
+- 日志：`D:/supervisor/logs/goauto-admin-api.log`、`D:/supervisor/logs/goauto-admin-ui.log`；对外分享只能保留脱敏结构摘要。迁移输出不得暴露凭据或业务原文。
+- 管理员刷新页面后可进入 `http://127.0.0.1:9527/#/client-keys/index`；菜单缓存未更新时重新登录。已验证列表空态、创建弹窗加载 12 模块及 HTTP 风险提示；未实际创建密钥，真实客户端读写及停用闭环仍待范围明确的验证。线上 GoAuto/Nginx 未重启或发布。
