+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立单元工单。采购、创建订单、真实个人或生产数据、权限、安全、并发、迁移、删除、发布和不可逆操作始终升级为高风险，必须具备对象和范围明确的人工授权；已有有效授权时不机械重复确认，范围或环境发生实质变化时重新确认。永久禁止付款以及设备、隐私、AI 和真机安全红线不可裁剪。

+## 项目治理模式与不可裁剪底线
+
+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。

-- 每次成功受理就地重试都会为同一任务预建一个新的 `pending` attempt，保存本次规则哈希；正常 Start 复用并转为 `running`。因此尝试次数、每次规则哈希和失败原因均可追溯，且不限制人工重试次数。

+## 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。
