merge: integrate main and purchase fixes for release (#234)

Allow up to two consecutive evidence-free PayActivity transition samples after the single safe Back; fail on the third post-Back sample (200ms cadence) to preserve a finite no-click payment boundary.

-- 用户可以使用中文、英文或合理的中英混合语言交流；默认使用中文分析、回复、编写工单和维护内部项目文档。
-- 代码标识符、命令、参数、路径、文件名、API 名称、协议名、日志和错误原文保持原样；必要时补充简短中文解释。
-- 用户明确要求某次回复或交付物使用其他语言时，按该次要求执行，不改写接口契约或影响搜索和执行的原文。

 - 高风险修改必须停止并等待人工确认：创建订单、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。
 
-### 项目治理模式与明确授权后的执行
-
-- 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，以及涉及 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、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按高风险任务处理；未取得有效人工授权时必须停止。
-- 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必须重新确认。平台自身强制的审批、安全策略或权限限制继续有效。

 ## 2. 哪些改动需要工单
 
-完整独立需求、新页面、跨模块功能、范围不明确的变化，以及接口、数据库、权限、并发、状态机或安全边界变化必须先有单元工单。采购、创建订单、数据库迁移、删除数据、发布和其他不可逆操作无论规模大小都必须建单。
+新功能、缺陷修复、重构，以及接口、数据库、权限、并发、状态机、安全或用户界面变化必须先有单元工单。
 
-以下低风险改动在范围明确、容易回退、不改变接口、数据结构、权限或安全边界，且不属于上述高风险事项时可以直接提交：
+以下小改动只有在范围明确、容易回退且不涉及上面的必须建单项时才可以直接提交：
 
 - 只改错别字、注释或文档措辞；
 - 只做格式化、导入排序或不跨文件的内部变量改名；
 - 补充类型标注或文档字符串且不改变行为；
 - 补充不改变产品行为的测试；
 - 删除已经确认无人使用的死代码；
-- 修复预期行为明确、影响局限于单个模块的低风险缺陷；
-- 不改变对外行为、入口、配置和验证方式的局部内部重构；
+- 修复单文件、低风险且只恢复已有明确行为的缺陷；
 - 只修改用户看到的界面显示文案，并且满足本文件「工单与设计证据双门禁」的全部豁免条件。
 
 直接提交仍须保护无关改动、执行受影响范围的最小验证并写清提交说明。有任何不确定，或涉及接口、数据库、状态、权限、安全、并发、用户界面时，必须退回单元工单流程。代码组件名、类名、变量、国际化键、API 字段和数据库字段不是显示文案，不适用豁免。

 - 提交只包含当前工单相关文件，提交信息引用工单号。
 - 优先运行项目档案记录的格式、单元、契约和集成测试。
 - Windows 环境优先使用当前已配置的 PowerShell；可选择时优先 PowerShell 7 `pwsh.exe`，不得仅为设置编码重复启动一层 PowerShell。
-- Windows 命令不得默认套用 Bash 语法。复杂正则优先使用变量或 `rg -e`；包含引号和换行的脚本正文优先使用单引号 PowerShell here-string；`foreach`、`if` 等语句块保持在同一个 PowerShell 解析上下文中；`rg` 使用真实目录配合 `-g/--glob`，不要把 Bash 风格通配路径作为目录参数。
 - 文本文件读写在命令支持时显式指定 UTF-8；文件解码和控制台输出分别处理，只有出现真实乱码或已知宿主非 UTF-8 时才设置当前进程的输出编码或 Python UTF-8 环境变量。
 - 不得默认使用 `-ExecutionPolicy Bypass`；只有可信 `.ps1` 确实被执行策略阻止且没有更小替代方案时，才对该次进程使用并在工单记录原因。

 - 当前设备只可重试自身最近 30 天内、服务端标记 `retryable=true` 的正式采购失败任务；列表和详情都只能发起单任务重试，不支持多选、批量或自动重试。
-- 普通“重试采购”调用既有 `AgentRetry → BatchRetry → Create`：原失败任务及其商品、目标规格、执行规格、价格和执行记录保持不可变；服务端根据当前 SYB、虾皮/PDD 档案、当前采购规则和当前设备创建不同 `purchase_task.id` 的新任务。
-- 新 SYB 采购任务继续遵循 #215 的强制当次规格探测，首趟不得直接使用历史任务的规格决策；当前档案、规则、价格、设备或能力门禁不通过时拒绝创建，旧任务保持失败状态。
+- 普通“重试采购”调用就地 `/reset`：复用原 `purchase_task.id`，只新增 attempt；新 attempt 使用当前有效采购规则和最新版 Agent 代码，商品、目标规格、执行规格、数量、价格、地址及既有规格决策等业务快照保持不变。
+- 就地重试不恢复已经消耗的真机规格探测资格；目标规格存在但对应执行规格为空时必须拒绝，不能进入正式采购阶段。需要按替代商品或已变化业务规格重新决策时，必须走明确的新任务流程。
 - 已出现 `order_submit_started` 证据，或存在不可逆时间、订单提交请求、PDD 订单号、下单时间的任务一律拒绝重试，并提示走既有“授权重新采购”流程，防止重复下单。
-- `requestId` 按“来源任务 + 请求”幂等；相同请求重放返回同一新任务，不重复创建。
-- Android 只在服务端 `retryable=true` 且状态为 `failed` 时显示普通“重试采购”。确认和成功反馈必须说明旧任务保留、新任务读取当前档案和规则、可能创建待付款订单且系统不会支付。
-- 历史兼容的就地 `/reset` 服务端入口不得把“目标规格存在但对应执行规格为空”的任务恢复到正式采购阶段；此类异常快照必须拒绝，并提示创建新任务。Android 普通重试不再调用该入口。
-- 替代商品匹配完成后的“继续采购”和 Admin 批量重试继续使用同一新任务语义；取消订单、修改既有订单和支付仍禁止。真机重试可能进入创建待付款订单流程，执行前必须再次取得人工授权。

 ## SYB 采购强制当次规格探测（#215）
 
-- 每个新 SYB 采购任务固定执行“首趟只读探测 → 服务端确定性优先/必要时 AI → 固化任务级精确规格 → 第二趟正式采购”。首趟只打开一次浏览器商品链接；匹配期间当前设备保留给同一任务，不领取其他采购或采集任务；第二趟复用 PDD 当前页，不再次打开链接，也不严格核验标题、goodsId 或页面指纹，但仍要求 PDD 包名与商品/规格/订单页面结构安全证据。已有长期映射只作商品档案事实，不直接进入任务执行规格。
+- 每个新 SYB 采购任务固定执行“首趟只读探测 → 服务端确定性优先/必要时 AI → 固化任务级精确规格 → 第二趟正式采购”。首趟只打开一次浏览器商品链接；匹配期间当前设备保留给同一任务，不领取其他采购或采集任务。连续进入第二趟且当前仍有 PDD 商品页或规格面板强证据时复用当前页、不再次打开链接；手动同任务重试，或当前处于 Agent、其他应用及缺少上述强证据时，重新打开任务固化的商品 URL。复用或重开均不严格核验标题、goodsId 或页面指纹，但仍要求 PDD 包名与商品/规格/订单页面结构安全证据。已有长期映射只作商品档案事实，不直接进入任务执行规格。
 - 首趟候选与 `taskId`、`taskAttemptId`、`deviceId`、规则快照哈希和幂等结果哈希关联；第二趟失败不得回到首趟循环探测。备货 `stock/direct_select` 没有 SYB 目标规格，继续使用用户逐字选择的档案规格，不进入本规则。
 - 候选和 Provider 结果仅保存颜色、尺码原始标签及结构化决策，不保存控件树、整屏截图、账号、地址、订单或支付数据；付款仍永久禁止。

 - 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。
+- 偏好只作用于此入口，不影响采集、其他创建入口和采购重试。浏览器存储失败时仍允许手动操作；刷新或关闭再打开浏览器可恢复，清理浏览器数据或沿用现有退出登录清理存储行为后需重新选择。
