+# 项目协作约定
+
+## 当前项目
+
+本目录 `browser_use/school-assistant/` 已转为 **橘子拓客（browser-use 桌面实验版）**，首个平台小红书。同级 `assistant/` 是独立项目，不能把其运行结果或验证状态算到本项目。
+
+新会话先读 `docs/DESIGN.md` 与 `docs/PROGRESS.md`。旧学校产品设计/启动说明归档在 `docs/archive/`；历史学校任务、NLU、角色准入、填报与审批状态机不接入新入口。
+
+## 当前技术路线
+
+Electron + React/TypeScript + FastAPI + browser-use 0.13.10 + PostgreSQL 17。`backend/prospecting/` 是当前业务编排与 API，`backend/browser/` 提供通用执行和页面取证；只保留 `backend/orchestrator/progress_doc.py` 的通用进度记录能力，不调用原学校 Orchestrator。
+
+链路：自然语言委托 → 意图与必要追问 → 分阶段搜索/笔记及讨论回复取证 → 独立分析/主页核对/导出或明确授权的跟进 → 独立复盘与评价。操作经验与个人来源分开；同一任务可修订目标，记录目标版本、保留来源及动作记录，不自动重放已成功或结果未知的动作。
+
+## 命令
+
+- `npm ci` / `npm run backend:setup` / `npm run db:up`：安装前后端与启动独立数据库。
+- `npm start`：构建并启动桌面应用。
+- `npm run check` / `npm run build` / `npm test`：类型、构建和后端测试；编排修改要跑完整后端测试。
+- `npm run backend`：单独启动本项目后端。
+- `npm run backend:lock`：以 universal 模式更新跨平台 Python 哈希锁，不能只在 Windows 冻结出无平台标记的依赖。
+
+## 约定
+
+- Key 由本项目 `.env` 或应用设置提供，不从其他项目复制，不输出到日志、对话或版本库。默认 `deepseek-flash`，图像输入和JSON输出适配以实际官方文档和测试为准。
+- 小红书登录由用户在实际页面完成；登录、验证码或平台限制要暂停。不把网页登录状态或私有接口凭据交给模型。
+- 当前用户授权开发和运行应用，未授权实际关注、评论或私信触达；不实现自动触达为默认行为。
+- 默认无篇数/评论数/总步数业务配额，无自建余额。用户明确数量才约束；单次请求超时不代表整个任务结束。真实上游限流/欠费/平台限制准确汇报，程序停止事件优先于模型总结。
+- 发现候选须有明确交付终点：沿用用户给出的候选人数；未给人数或指定页面/篇数/明确一轮范围时，只补问“这次先整理多少位候选？”。人数按有稳定来源身份的人去重，身份未知单列不凑数。达标当步停止；未达标或无进展交付阶段结果，不无限重复。模型不能替用户猜目标数量。
+- 相同来源、标准和模型复用已有判断，新增/变化来源增量分析；明确“重新分析”才强制重做。按任务/阶段累计供应商实际usage，解析失败已返回的用量也保留；未知用量与历史缺项不能写成0或当完整账单。
+- 跟进工具需批次授权、已核对的账号/对象和确定的私信内容；红色失败标记或结果未知暂停当前账号全部后续私信。解除须新页面核对和用户明确确认，不自动重发。开发方案批准不等于真实触达测试授权。
+- `save_source` 逐字核对实际来源容器，`evidence.json` 为任务来源恢复快照。待核不等于已确认客户；mock、本机夹具、模型连通和真实平台表现分别报告。
+- 交付状态、必要字段与知识可靠性分开：仅用户明确要求的字段计达标；不统一要求人工复核。新知识依据程序前后证据自动验收，模型报告与用户👍/👎不增加技术成功数；重复任务/对象不能重复抬分，明确相关反证暂停相应场景。历史缺失统计标未记录，不迁移补成功。方法与事件按工作区隔离，原话/账号留在任务证据，跨任务只保存通用方法及引用；目前无真实跨任务优先方法或获客效果结论。
+- 旧编译字段只在明确继续时重核，保留后来确认的人数和旧目标/证据/文件版本，不在读取或启动时自动修改。评论数量不代表已读；评论区推进及作者主页使用受约束工具和当前真实入口，悬浮卡无推进不反复点。Schema诊断仅留程序声明字段路径/标准错误类型，不保存input/msg/原始响应；具体连续失败原因不能被笼统done覆盖，程序错误不充当方法反证。新建内嵌及续跑均须带当时目标版本，旧缺失不补造。
+- 两套历史数据库字段暂保留兼容，新任务/经验以 `prospecting_workspace` 作用域隔离。中心学校审核服务不由当前桌面入口自动运行。
+- 每次完成阶段同步 DESIGN/PROGRESS。保护已有改动，未获明确要求不提交或推送。
+- 数据库15433、API8788、CDP9333、控制8797；不关停其他项目服务。Electron内嵌视图不直接隐藏，按原park保留窗内2px，避免截图挂起。
+
+## 每轮结束汇报（用户 2026-10-28 明确要求）
+
+每次结束都用简短、具体的语言交代以下内容，成功、失败或受阻均适用：
+
+1. **问题出在哪**：说明现象、已确认的原因与依据；尚未确认的原因明确标为待查。
+2. **怎么修复、结果如何**：说明实际修改与验证结果，区分本机测试、真实模型、真实平台；业务任务写明实际来源/线索及未完成范围。未修好的问题必须保留，不能只报测试通过。
+3. **接下来怎么走**：按优先级列出下一步具体动作、目的和验收依据；需要用户补充的资料明确指出。沿用用户明确范围、既有结果和累计进度，不因总结或改轮次清空任务或动作记录。
+
+汇报同时留下可复用的方法或规则；没有可沉淀经验时如实说明。实际开发、修复和工程验证同步到 PROGRESS，已定方案与实施顺序同步到 DESIGN。普通确认/说明只需简述，不为凑格式虚构故障、改动或验证，也不因此启动额外业务任务。

+# 橘子拓客
+
+基于 Electron、FastAPI 和 browser-use 的桌面拓客 Agent。首个平台为小红书：自然语言描述目标 → 必要追问和计划 → 笔记、评论及回复取证 → 需求判断与主页核对 → 名单导出或明确授权的跟进 → 独立复盘和评价。
+
+项目目录暂保留 `school-assistant/`；已从学校办事业务转向 AI 拓客。原查课、谈话、角色准入、填报和审批链路不再挂载到当前应用。原设计与说明见 `docs/archive/`。同级 `assistant/` 独立维护。
+
+## 安装与启动
+
+需要 Node.js 20.19+、uv 和 Docker Desktop。Windows 和 macOS 使用同一组命令，在本项目目录执行：
+
+```sh
+npm ci
+npm run backend:setup
+npm run db:up
+npm start
+```
+
+Python 环境使用 3.12，依赖锁为跨平台解析；Electron 自带浏览器，无需另外安装 Playwright Chromium。
+
+默认 API 端口 8788、Electron CDP 9333、控制端口 8797、PostgreSQL 15433。启动前请确保这些端口未被其他应用占用。源码模式下配置和任务证据在本项目，打包模式在应用 userData。
+
+## 配置模型
+
+首次可复制 `.env.example` 为 `.env`，也可运行后在右上角“模型设置”填写 Key 并测试。API 不返回已保存 Key；Key 不进入版本库。
+
+默认 `deepseek-flash`，官方当前对应 DeepSeek-V4.1-Flash-1017，支持图像输入；可选 `deepseek-v4-pro` 做文本判断，此型号当前不支持图像输入。已为 browser-use 0.13.10 补齐新模型名的 thinking/结构化输出适配，不依赖旧型号别名。
+
+没有 Key 时应用仍可启动、描述目标并保存任务，但会明确停在“配置模型”，不会把演示数据当成真实采集结果。
+
+## 第一次使用
+
+1. 输入一段话说明任务，也可提供实际笔记或账号链接。助手生成可展开的理解卡，只追问必要缺项。
+2. 发现候选先确认交付人数；已给人数、指定页面/篇数或明确一轮范围则直接沿用，不反复追问。按可区分身份的人去重，身份未知来源单列，不凑人数。无默认笔记数、评论数或60步业务上限。
+3. 需要登录或验证码时，任务暂停，在右侧浏览器中处理后继续。
+4. 查看原话、来源及待核结果，导出CSV；作者、评论者和回复者分别判断。结果下可点赞、点踩或纠正单条线索。
+5. 同一对话可以补充条件、修订标准或继续任务。来源与动作历史保留，经验草稿仍需跨任务验证。
+
+默认发现整理不实施触达。关注/私信先核对账号与对象，用户选择具体批次；私信另需确定内容。红色失败标记或未知结果会暂停当前账号后续私信，不能自动重发。跟进控件目前经过本地合同和页面夹具验证，真实平台链路尚待单独授权验收。没有读到的内容保留为未知，摘录不代表已确认客户身份。
+
+## DeepSeek Search / Fetch
+
+可选公开网页资料工具已提供：`POST /api/research/search` 与 `POST /api/research/fetch`。输入区“补充公开网页资料”默认关闭，开启后可补充公开资料。Fetch 可供独立公开资料读取，不使用小红书登录态，不保证能抓取登录后笔记或评论。
+
+它们与模型使用同一 DeepSeek Key，独立按请求计费；真实可用性须通过实际账号验证。
+
+## 验证与文档
+
+```sh
+npm run check
+npm run build
+npm test
+```
+
+测试中的夹具和 mock 不代表真实平台或真实模型已验证。当前设计见 [DESIGN](docs/DESIGN.md)，实际完成与限制见 [PROGRESS](docs/PROGRESS.md)。
+
+核心模块：`backend/prospecting/` 新业务编排与来源分析、`backend/browser/` 浏览器执行与取证、`backend/research.py` 公开检索、`renderer/` 拓客工作台。当前兼容数据层保留 `school_id/student_id` 内部字段作为工作区/操作者标识，新作用域 `prospecting_workspace` 与旧学校任务和经验隔离。
+
+品牌图标成品位于 `resources/brand/`，常规构建自动复制并接入，无需重新生成。维护图标时可通过已有 `sharp` 运行 `scripts/generate-app-icons.mjs`；未在项目安装时，用 `ICON_SHARP_MODULE` 指向现有模块的绝对路径。改名保持原npm包名、appId及用户数据目录，已有Key、登录态与历史继续沿用。

+# AI 拓客助手优化方案 v0.1
+
+状态：用户已要求开始实现。日期：2026 年 10 月 28 日。项目：`browser_use/school-assistant/`，首个平台为小红书。下文保留审核时的设计基线，当前实现及待验收项目见 [DESIGN](DESIGN.md) 和 [PROGRESS](PROGRESS.md)。
+
+建议把产品主线调整为：**用户用自然语言交代目标，助手通过真实页面完成分阶段任务，保留需求证据和执行进度，将验证过的方法沉淀为可复用链路。** UI 围绕对话组织，线索、浏览器、任务进度和评价围绕对话展开。
+
+本次审核决定产品方向、交互和实施顺序。通过后再修改程序；本方案不授权实际关注、私信或其他对外触达。同级 `assistant/` 继续独立。
+
+## 1 已讨论的方向和本次新增建议
+
+| 范围 | 已讨论的方向 | 本版提出的具体机制 |
+| --- | --- | --- |
+| 任务入口 | 输入一段话，识别意图，必要时再追问 | 可编辑的目标理解卡，显示已知条件、推断和待确认项 |
+| 执行范围 | 不强制填写篇数、评论数，不设置软件余额 | 内部分段执行和自动接续；阶段汇报列出已覆盖与未覆盖范围 |
+| 评论阅读 | 评论以及展开后的回复都可能有需求 | 保存讨论层级、发言人、回复对象和各自原话，按人判断 |
+| 业务链路 | 查找、核实、导出、关注和私信属于不同阶段 | 操作能力、阶段模板、本次计划三层组合，按条件选择分支 |
+| 页面操作 | 沿实际页面操作，过程可见 | 每次动作核对页面变化，保留中断恢复点和动作记录 |
+| 平台受限 | 停下来告诉用户，提供合适的替代路线 | 暂停受限阶段，保留已完成结果，展示替代路线及切换影响 |
+| 经验与评价 | 边做边沉淀，任务结束可点赞或点踩 | 独立复盘形成经验草稿；反馈关联任务、证据和链路版本 |
+
+表格右栏是待审核的落地设计，尚未实现。
+
+## 2 当前问题和改造目标
+
+当前程序已有内嵌浏览器、暂停接管、页面截图、来源保存、文字分析和经验数据结构，但入口仍要求填写业务条件及阅读数量。阅读以首层评论为主，展开回复、主页身份核实、名单导出、关注与私信尚未形成完整链路。
+
+最近分析的实际任务保存了 4 篇笔记和 20 条首层评论，只覆盖了 3 个关键词中的第一个。模型在累计 51/60 步时主动结束，文字却称“预算耗尽”。这说明需要同时修正执行策略和停止原因，不能只改提示文案。本轮经验草稿和复用回执均为 0，现有数据结构也不能代表学习闭环已跑通。详细依据保留在 [D24 日志分析](PROGRESS.md)。
+
+改造后的验收应回答三个问题：能否按用户真实目标完成合适的阶段；每条线索是否有可核实的来源和正确归属；下一次遇到相似任务时，能否可靠复用上次验证的方法。客户是否回复、是否成交另行记录。
+
+## 3 对话入口和桌面布局
+
+### 目标理解
+
+用户可以说“我做杭州装修，帮我找最近准备装修的人”，也可以直接给一篇笔记、一个账号，要求分析、整理名单或继续已有任务。系统先判断本次属于需求研究、发现候选、核对对象、整理导出还是跟进，再生成计划。
+
+一张简短的理解卡显示“要做什么、按什么标准、准备走哪些阶段”。助手自动生成搜索词，并允许用户修改；地区、产品、客户类型不统一设为必填。如果用户只想整理现有账号，就不再追问产品。如果用户要求筛选“适合我的客户”，又没有任何业务背景，才需要补问会影响匹配的条件。
+
+例如，用户说“我是杭州的装修公司，找最近在装修的人，整理名单”，可直接开始搜索和核实。用户说“把这批人私信一下”时，先使用对话中已经明确的名单和话术，只有名单有歧义或消息内容缺失时才追问。追问不应把旧表单拆成多轮必答题。
+
+信息足够的搜索、阅读和整理可以开始，计划卡随进度更新。用户中途修正标准时，保存目标版本和修改点，说明哪些结果需要重新分析。只有新增页面工作需要继续执行，已有来源不重复采集；已有关注或消息记录不会因修改目标而清空。
+
+### 布局
+
+| 区域 | 内容 |
+| --- | --- |
+| 左侧 | 会话与任务历史，支持回到中断位置、查看既有成果 |
+| 中间 | 对话、理解卡、简短进度、线索卡、导出结果、任务评价 |
+| 右侧 | 执行中的真实浏览器，可接管；结束后显示带实际时间的只读截图与停止原因 |
+
+默认保持对话清爽。搜索词、筛选依据、经验详情和执行日志按需展开。结果卡可使用“复制、导出、👍、👎、更多”操作，评价入口紧贴它所评价的结果。
+
+## 4 执行范围和停止规则
+
+### 取消人为业务配额
+
+取消默认的“本轮最多阅读”“每篇最多评论”和固定 60 步业务上限，也不引入自建余额或积分。用户主动指定“先看 10 篇”或“只整理这 5 个账号”时，尊重这次明确范围。
+
+页面读取、单次模型请求仍可分批并设置超时。这些属于执行机制，每批结束保存位置、已读集合和待办项，沿同一任务继续，不能把一个批次结束显示为整个目标完成。真实服务的欠费、限流或不可用要准确提示；取消软件配额不表示上游调用免费。
+
+实施时同时核对表单、接口校验、编排、执行器和框架提示中的总量限制，将单次超时与整个任务的终止分开。不能只隐藏输入框，后台仍以旧步数或固定总时长自动收尾。
+
+### 建议的默认收尾方式
+
+开放式“帮我找客户”没有全站读完的终点。建议按当前目标生成检索路线，持续处理可访问的新候选并分段汇报。**关键词尚未覆盖、回复尚未展开、任务仍可推进时，不以固定步数或模型一句总结提前宣告完成。**
+
+当前路线已无新增候选、可访问内容已处理，或持续重复操作没有进展时，给出阶段结果，说明已覆盖范围、未读部分和继续方式。新的行业方向、地区扩展或触达动作会改变目标时，再由用户决定。这里的“阶段收尾”不等于已经穷尽平台或已经找到客户，也不自动安排后台定时运行。
+
+| 状态 | 用户看到的含义 | 后续处理 |
+| --- | --- | --- |
+| 执行中 | 当前阶段正在推进，有可核实的新进展 | 保存检查点并继续 |
+| 阶段结果 | 当前路线处理到一个明确节点，仍可继续或调整 | 展示覆盖情况和后续选项 |
+| 已完成 | 用户明确交代的范围和产物已完成 | 提交结果并进入复盘 |
+| 等待用户 | 必要信息、登录或验证需要用户处理 | 保存位置，补齐后继续 |
+| 平台或服务受限 | 页面限制、真实限流或服务错误阻断相应动作 | 停止受限阶段，说明依据和可选路线 |
+| 用户停止或异常中断 | 用户主动停止，或程序未能继续 | 保留已完成结果与待恢复动作 |
+
+停止原因由程序根据实际事件记录，模型只负责解释。模型主动结束、页面无新增、请求超时、平台上限和用户停止必须区分。历史任务的 51/60、59/60 和失败记录继续保留；新策略生效后续跑旧任务，需要记录策略版本和接续位置，旧配额不能继续作为隐藏阻断。
+
+## 5 分阶段链路和证据
+
+主线为：**理解目标 → 搜索发现 → 阅读笔记与讨论 → 判断需求 → 核对主页 → 整理交付或获授权的跟进 → 复盘。** 实际任务可以从任意合适阶段进入，也可以只执行其中一段。
+
+| 阶段 | 核心动作 | 成功依据 |
+| --- | --- | --- |
+| 搜索发现 | 生成或调整关键词，使用实际搜索入口，点击真实结果 | 记录检索路线和已访问内容，避免只看第一个词 |
+| 阅读讨论 | 阅读正文、首层评论，展开相关回复并继续阅读 | 保存实际加载的原话、层级和发言人，核对新增内容 |
+| 判断需求 | 按当前用户目标判断每个发言人自己的需求 | 理由能回指本人原话，模糊信息保留为待核 |
+| 核对主页 | 点击对应头像，查看主页及页面可见账号信息 | 候选人、评论和主页能对应，未知信息保持未知 |
+| 整理导出 | 去重并整理用户要求的字段 | 清晰区分昵称、小红书号、主页链接和笔记标识 |
+| 关注或私信 | 关注需明确对象范围和动作，私信还需明确消息内容 | 核对关注状态或实际发送结果，保留动作记录 |
+| 复盘 | 汇总结果、阻断、未完成项和可复用操作 | 形成结果卡及有页面依据的经验草稿 |
+
+### 评论与展开回复
+
+正文、首层评论、子回复分别保存，关联所属笔记、父评论、讨论根和回复对象。页面无法确认的身份或关系留空，不能猜补。父评论作者说“我家在杭州”，不能让其下每位回复者都变成杭州客户；回复中引用别人的需求也不能自动归给自己。
+
+展开后先判断是否出现新内容，再采集和去重。遇到入口失效、登录限制或多次没有新增，记录原因并换合适路径。“没有评论”“尚未展开”“只读取了一部分”“当前无法访问”分别表达，不反复点击同一入口，也不把未读内容当成没有需求。
+
+### 需求判断和名单
+
+建议把“正在装修”和“明确寻找装修服务”作为两个独立维度。前者可能符合广泛寻找装修人群的目标，后者才能支持更强的服务意向判断。模型不能擅自把宽目标改成窄目标，也不能把一般交流升级成购买意愿。
+
+例如“我给你 8 万来我家装成这样”可保留为待核信号，同时说明可能是认真委托，也可能是调侃。主页信息、后续上下文和用户纠正可以补充判断，不能抹掉原始出处。
+
+导出建议包括：昵称、页面可见的小红书号、主页链接、需求原话、来源、观察时间、判断理由、待核事项和跟进状态。IP 属地单独保存，不能直接填成项目所在地。未知字段留空并说明；已核对的账号可归并多条证据，未确认同一身份时不强行合并。首版导出建议提供 CSV，后续按使用习惯增加 Excel。
+
+## 6 页面操作和跟进受限
+
+### 自然页面路径
+
+优先沿搜索、结果、详情、评论、头像和主页等实际可见入口操作。点击后确认页面或控件状态变化，阅读过程中保留可接管的浏览器。用户提供的有效分享链接可以正常打开；不手工拼接临时签名链接，也不把固定坐标轨迹沉淀为通用能力。
+
+“像人一样操作”落实为路径合理、状态可见、动作有反馈和失败能停下，不承诺因此不会触发检测。随机抖动鼠标或伪装身份不作为产品目标。遇到验证码交给用户处理。Browser Use 官方也明确说明，浏览器配置不能保证避开或解决所有验证码，见 [Browser Use README](https://github.com/browser-use/browser-use/blob/main/README.md)。
+
+### 关注与私信的授权范围
+
+“帮我找客户”只启动与发现和整理有关的阶段。关注需明确对象范围和动作；私信还需明确消息内容，可复用对话中已确定的话术。信息充分后可以按范围连续执行，无需逐人重复确认；缺少必要内容或范围发生实质变化时再澄清。关注是否是私信前置条件，以当前页面能力为准。
+
+对已关注的对象跳过重复关注；发送超时或结果不确定时，先核对会话记录，不能直接重发。每次动作保留准备、执行中、成功、失败或结果未知状态，应用重启也不能把成功动作当作新动作重放。动作前再次检查用户授权范围和当前账号状态，避免沿用过时计划。
+
+### 红色感叹号和平台上限
+
+将用户描述的红色感叹号作为**立即暂停当前账号私信阶段的信号**：停止继续发送，保存页面提示和截图，区分已发送、失败、结果未知及未发送名单。
+
+只有页面明确提示每日上限，才告知“今日私信达到平台上限”。单独出现红色感叹号时，表述为“发送失败，原因待确认”，不能将图标统一等同于每日上限。未核实前不重试，也不自动给名单下一位发送；不假定次日一定恢复。
+
+暂停后提供可行的独立分支，例如整理导出当前名单、核实已有候选或查看当前成果。先说明每条路线的产物和切换影响，由用户选择；不通过换账号或换入口继续同一种受限发送。小红书社区公约要求尊重他人停止交流的意愿，避免不受欢迎的广告打扰；链路还应记录明确拒绝并跳过后续触达，见 [小红书社区公约 2.0](https://pgy.xiaohongshu.com/help/detail?id=1eda0a065dd894063c2e029a49e8f6a1&userType=4)。
+
+## 7 边做边沉淀的复用机制
+
+### 三层复用
+
+| 层次 | 保存什么 | 示例 |
+| --- | --- | --- |
+| 操作能力 | 适用页面、参数、前置条件、页面定位方法、成功依据、失败恢复和版本 | 展开一组回复；读取主页可见小红书号 |
+| 阶段模板 | 能力组合、顺序、分支、阶段产物及中断恢复方式 | 阅读讨论并核对候选；整理名单；核实后私信 |
+| 本次任务计划 | 用户目标、筛选标准、对象、关键词、内容版本、授权范围和进度 | 杭州装修候选名单，先核实再导出 |
+
+行业、客户标准和消息内容属于本次任务，不写死在通用操作经验中。通用经验也不保存个人昵称、评论原话和用户账号；这些留在任务证据和名单内。
+
+### 经验的形成和验证
+
+每个阶段结束或异常中断后，由独立复盘步骤整理执行轨迹，抽取有证据的方法，形成经验草稿。复盘不占用最后几个采集步骤，也不依赖模型记得调用保存工具。
+
+草稿记录来源任务、页面证据、适用条件和已知失败。后续在不同对象或参数下试用，动作的成功依据相符后才能升级为可复用版本。失败则记录不适用条件；页面或关键控件变化时降级或停用相应版本，再验证替代方法。模型总结、一次点击和用户点赞都不能单独把经验升级为“已验证”。
+
+复用时先检查当前条件，成功后继续下一阶段，失败则回到页面观察或明确中断。页面能力、任务事实和业务判断分开保存，避免“复用上次链路”变成重复上次客户名单、搜索词和话术。
+
+## 8 评价和链路推荐
+
+### 任务评价
+
+任务结果下提供 👍 和 👎。点赞一键完成；点踩后可选原因，例如“人群不对”“没有真实需求”“任务没完成”“过程太慢”，也允许自由说明。原因均可跳过，不要求长问卷。
+
+同时支持单条线索纠正，例如“这人已经装完了”“这是玩笑”“这是有效咨询”。反馈关联当时的目标、任务、证据快照、模型配置和链路版本，保留原判断及更正记录。必要时重新分析已有证据，避免为一次纠正重跑整条浏览器链路。
+
+| 评价维度 | 记录内容 | 用途 |
+| --- | --- | --- |
+| 执行质量 | 阶段是否走通、是否重复、为何中断 | 改进页面能力和恢复策略 |
+| 用户认可 | 任务点赞点踩、线索纠正 | 调整筛选和呈现方式 |
+| 业务效果 | 是否回复、是否确认需求、是否合作 | 在相近场景中比较链路效果 |
+
+业务效果标明来自用户反馈还是实际页面观察。任务点赞不等于所有线索有效，已发送不等于已回复，已回复也不等于成交。
+
+### 替代路线和效果积累
+
+早期按目标适配度、账号当前能力和已有证据推荐路线，展示“为什么适合、会产出什么、有哪些前置条件”。样本不足时标记为待验证，不先宣称哪条最容易获客。
+
+积累后，在相近业务、目标、地区和执行阶段中比较有效需求、回复、合作及失败原因，并显示样本量和观察范围。避免只按线索数量或点赞数排名；用户否定的候选和未回复结果也应进入评估，防止只记录成功案例。反馈先用于规则、经验和链路排序，不默认等同于训练模型。
+
+## 9 模型和 Search Fetch 的使用
+
+保留当前 DeepSeek 接入，让页面执行使用具备图像理解及结构化动作能力的模型，文字复核使用适合文本分析的配置。模型名称、版本和调用错误在任务记录中可追溯，实施时再核对官方可用版本，不靠升级整个 browser-use 框架解决业务问题。
+
+截图中的 Search/Fetch 可以用于公开网页资料补充，例如行业背景、公开需求表达和链接正文。它们不共享小红书登录态，不能代替登录后评论或回复的实际阅读，也不能把搜索摘要当作已经核实的客户证据。具体能力以 [DeepSeek Search/Fetch 文档](https://api-docs.deepseek.com/zh-cn/guides/search/) 为准。
+
+建议保留显式开启公开检索的设置；开启后助手在相关任务中按需使用，结果标明来源。缺 Key、调用权限或真实服务余额时，清楚提示需要处理的配置，不伪装成“本轮阅读额度用完”。Key 继续仅由本项目设置管理。
+
+## 10 实施顺序和验收
+
+沿用现有 Electron、React、FastAPI、browser-use 和数据库结构，在当前拓客模块逐步调整。先把任务和页面事实表达准确，再完善回复、导出和跟进，最后用真实跨任务验证经验复用。不另建一套总框架，也不恢复学校业务链路。
+
+| 阶段 | 交付 | 主要验收 |
+| --- | --- | --- |
+| 第一阶段 对话与执行状态 | 对话入口、理解卡、必要追问、取消默认业务配额、准确停止原因、分段接续 | 信息足够直接开始；必要缺项才追问；持续推进不被固定60步截断；部分结果和未覆盖范围准确，暂停重启可恢复 |
+| 第二阶段 阅读与名单 | 展开回复、讨论关系、来源元数据、主页核对、账号去重、CSV导出 | 父子发言不混淆；无新增不反复展开；作者信息不再阻断正文；未知ID不猜补；导出可追溯到证据 |
+| 第三阶段 跟进与受限分支 | 授权范围、关注与私信动作、动作账本、失败暂停、替代路线 | 未授权不发送；已关注不重复；发送结果未知不重发；红色感叹号立即停后续私信；恢复不会重放已成功动作 |
+| 第四阶段 经验与反馈 | 独立复盘、经验版本、跨任务验证、👍👎及线索纠正、路线推荐 | 新对象或参数能复用；页面变化能降级；评价可归因；推荐显示依据，业务效果不冒充技术成功 |
+
+独立复盘和版本记录在前期先具备基础能力，第四阶段验收完整复用闭环。每阶段先做必要的本地验证，再区分真实模型、真实平台和业务结果。第三阶段真实触达验证，仍需用户另行给出明确对象范围和内容；方案审核本身不触发对外操作。
+
+每次交付都报告：**问题出在哪、实际做了什么及验证结果、下一步做什么。** 没有修复或尚未验收的项目继续列出，不能用测试通过代替真实业务完成。
+
+## 11 本轮审核重点
+
+建议按以下默认方案审核，可直接按条修改：
+
+1. **入口与布局**：采用左侧历史、中间对话和结果、右侧浏览器，业务表单退出默认入口，理解卡允许编辑。
+2. **收尾方式**：取消默认篇数、评论数和固定步数业务上限；按可观察进展分段继续，无新增或受阻时给阶段结果与未覆盖说明。
+3. **跟进边界**：查找整理不自动进入关注私信；关注需明确对象范围和动作，私信另需明确内容，信息充分后按范围执行。红色感叹号暂停整个当前账号私信阶段。
+4. **首版交付**：按四阶段推进，名单先支持 CSV；复盘独立运行，经验经不同任务验证后升级。
+5. **后期效果积累**：采用任务评价加单条线索纠正，分别统计执行质量、用户认可和业务效果，再逐步改进链路推荐。
+
+通过后将本方案中获批部分同步为正式设计和阶段任务；未获批部分继续保留为建议，不进入运行逻辑。

+# 橘子拓客：当前设计与实施范围
+
+> 2026-10-28 用户明确将本项目从学校办事助手转为 AI 拓客助手，首个平台为小红书。本窗口只开发此项目；同级 `assistant/` 独立保留。
+> 原学校设计见 [历史归档](archive/DESIGN-school-2026-10-28.md)，其中查课、谈话、角色准入、填报、审批与回查链路退出当前运行入口。
+
+> 用户已明确要求开始实现 [AI 拓客助手优化方案 v0.1](AI拓客助手优化方案-v0.1.md)。以下记录本次实施状态；真实平台与业务效果的验收另列，不由本地测试替代。
+
+> 2026-10-29 用户已批准执行 [结果交付与知识复用优化方案 v0.3](橘子拓客结果交付与知识复用优化方案-v0.3.md)。结果交付、必要字段、程序验收、独立证据排名及知识界面已首轮实现；实际跨任务复用、完整平台链路与业务效果继续待验收，不能由本地样本推导。
+
+> 2026-10-30 按用户《橘子拓客 纠偏方案 v1》调整方向：以正常规模候选交付的真实调用、token及时间衡量主链路，不继续D44回复直接父归属或预检专项。用户确认继续后已执行P1基线，实际交付2/10位并按取证停滞停止，等待监督确认后才进入P2；以下D20–D44记录作为历史，不作为继续专项开发或复测的授权。
+
+### P0：默认关闭实验性回复关系与预检
+
+`Settings.reply_relation_preflight_enabled`（环境变量 `REPLY_RELATION_PREFLIGHT_ENABLED`）默认 `False`，统一控制两个模型工具 `inspect_reply_relations` / `resolve_reply_target`、预检正则路由、编排、提示、执行gate及交付投影。默认不调用 `compile_preflight_policy` 改写意图；显式开启时保留原实现。续跑时也从已有Agent移除关闭工具并刷新动作Schema，保留实际浏览器及2px park规则。开关是后端启动配置，本轮未重启桌面端，不能把新进程离线审计说成现有进程已重载。
+
+`save_source` 仍逐字核对真实独立容器并先持久化来源；成功只证明原话核验及保存，不再因回复父关系未知记为unknown。`parent_resolution`、父/根引用、诊断及 `relations_checked` 独立保留，不猜父关系；工具下一步与默认提示不再要求补父容器、重存回复。用户明确要求关系时的交付条件仍独立校验，不能由保存success推出关系完整或整条获客链已完成。`evidence.json` 恢复及历史事实不回填。旧知识方法的同版本定义不可变，P0不改库或迁移旧文案；其保存成功不得解释成父关系成功，流程定义与成本口径留待P3按新版本处理。
+
+本机验证覆盖默认关闭、显式开启、历史投影、旧会话续跑、未知父关系保存与逐字核验。另以既有真实发现任务只读重建当前模型契约，确认25个动作中两个实验工具均不存在；证据为 `data/ui-verification/p0-default-tool-schema.json`。此为当前代码将发送的Schema审计，未发模型请求，不是历史请求或真实上游收到的回执；严格真实请求侧验收尚待取得。
+
+P1已重新启动当前代码，补齐P0真实请求侧核对：`task_76d551192d7e` 的44份出站动作Schema均关联同call_id的供应商response及succeeded；实际24个动作，两个实验工具均不存在。此回执属于P1新任务，不补写P0离线审计或历史任务。
+
+### P1：装修服务主链路基线（已测量，业务未达标）
+
+用户明确商品为装修服务，目标客户为近期要装修的用户，无地区限制；目标10位，只读，不设篇数或评论数上限。桌面创建独立任务 `task_76d551192d7e`，输入已有“10位去重候选”仍重复追问，按同一目标填10后继续，未修解析或调参。新增的代码仅为程序测量：真实模型出站契约的安全元数据、实际工具边界事件及 `scripts/measure-prospecting-baseline.py`；不记录参数、提示、Key或完整Schema，不改变请求和业务控制。
+
+任务以 `evidence_stalled` 停止：实际访问4篇，3篇取得核验摘录，保存正文3、评论6、回复0；分析9条后保留2位稳定来源身份候选，身份未知候选0，尚缺8位。单候选23.5次调用、570242.5 tokens、98.885秒；总47次调用/1140485 tokens/44个步骤/50次实际工具调用/197.77秒。实际总时间包括人数补问；供应商usage完整，缓存命中858496输入tokens，未换算费用账单。任务内 `baseline.json` 和PROGRESS保存分阶段指标及工具分布，不能将未达10位当作完整业务闭环或降本成功。
+
+已确认检查18次与保存12次占实际50次调用的60%；保存校验拒绝3次，末尾连续3次来源容器检查失败触发原保护；4次评论区推进中3条有记录的尝试均not_moved，展开0。最底层容器失败分支尚无法从持久化记录确认。P2应围绕这些实测问题将当前笔记内的推进、读取、逐字保存与展开程序化，保留原校验及真实失败原因；不继续回复父归属专项，不增加未经本轮失败支持的新约束。P1缺少10位完整基线，后续不能宣称已取得同等10位交付的50%降本验收。
+
+## 1. 产品与首个闭环
+
+用户用一段自然语言描述目标 → 模型识别意图、提取已有条件并生成关键词 → 必要缺项才追问 → 按阶段搜索/检查指定页面 → 阅读笔记、评论及回复 → 核对主页或整理导出 → 独立复盘与用户评价。对话支持在同一任务修订标准和继续，目标版本、来源和动作历史保留。
+
+当前首版交付：蓝灰玻璃面板的单段持续对话、可收放历史与设置抽屉、按需展开的执行浏览器、可展开理解卡、无默认阅读配额、真实停止原因、评论与回复取证、主页身份核对、CSV名单导出、点赞点踩与单条纠正、独立经验复盘、受授权的关注/私信工具及账号动作账本。继续保留页面证据、人工登录/验证、模型设置和可选公开资料工具。
+
+用户进一步指定按小鹅网页复刻视觉与动效；布局、粒子轮廓、翻转关键帧和验证范围见 [界面参考记录](UI_REFERENCE_PENGUIN.md)。动画与真实任务状态关联，减少动态时静态呈现，不用演示数据或动画冒充任务成功。
+
+用户已批准实施 [UI 优化方案](UI优化方案-v0.2.md)。当前已分离默认品牌粒子、对话粒子和结果组装，并接入必要补充、真实阶段、来源核验、名单表格、文件交付及受限后的独立路线。补充卡和路线提交校验任务及结果版本；文字与卡片回答沿同一任务接续，旧卡保留只读历史。精确粒子轨迹仍需参考连续画面对照，现为独立流动实现。
+
+2026-10-29 用户进一步指定品牌为类似“小火花”的造型：界面标识和默认粒子已改为共享圆润火花轮廓、独立浮滴和白色笑脸，使用贴合玻璃面板的银蓝配色，不使用用户提供的红色JPG。对话流动粒子和结果方阵继续独立保留；参考网页只指导布局及交互表现，不再沿用其品牌形象。
+
+同日正式改名为“橘子拓客”，助手昵称“小橘”。窗口、页面、关于面板及产品元信息统一名称；应用图标沿用现有银蓝小火花并加浅蓝圆角底，提供SVG、1024透明PNG、macOS ICNS和Windows ICO，源码运行时设置Dock/窗口图标，打包配置引用相同资源。npm包名、appId及既有用户数据目录保持稳定，改名不创建空配置或丢失历史；图标由 `scripts/generate-app-icons.mjs` 从已有SPARK路径离线生成，普通构建使用仓库内成品，不新增运行依赖。
+
+同日D39按实际任务状态调整输入框：消息提交中或当前任务 `running` 时，右侧显示转圈状态；HTTP提交返回后仍以持续任务状态展示，不因一次请求结束恢复发送箭头。执行中仍能输入并发送补充说明，停止沿用任务内按钮；暂停、等待补充及结束状态恢复发送图标，减少动态时保留静态进度图标。macOS窗口使用 `hiddenInset` 保留原生三个窗口按钮，40px浅蓝灰可拖动栏在按钮右侧显示标题；Windows/Linux保留原生标题栏，普通浏览器预览不显示桌面栏。内容及原生浏览器插槽按实际DOM边界下移，不改2px park或视图缩放。隔离界面已验证提交后持续转圈、补充、完成与停止的切换，真实原生标题栏核对见D39运行记录。
+
+`max_notes/max_comments_per_note` 默认 null，仅用户明确指定时生效。新拓客任务及迁移后续跑不使用60步或600秒总量终止；单次工具/模型超时仍保留。框架按无限执行范围运行，屏蔽预算收尾提示并保留消息压缩、用户中断和无进展保护。累计操作台账保留，损坏台账不重置为0。
+
+2026-10-29 用户补充：不能没有终点一直跑。发现候选以用户明确的 `target_candidates` 为交付目标，未给人数、指定页面、明确篇数或“先做一轮”范围时，只补问“这次先整理多少位候选？”。纯数字卡片/对话确认直接接续同一任务，不再调用意图模型。人数与笔记/评论条数分别处理；程序检查用户原话，不接受模型擅猜10位或20位。复杂/中文数字表达暂保守补问，不能自动猜值。检查、研究、导出及明确跟进范围不强求候选人数。
+
+候选按来源作者主页的稳定身份合并，同名不合并；只有线索里的昵称/链接推测不算身份证据。身份未知来源单列，不计达标；主页可见小红书号仍需独立核对。逐步保存后按剩余目标分段分析，达标时在下一次网页/模型调用前停止；关键词未遍历范围继续如实保留。未达标、采集失败或同页反复取证无新增时交付阶段结果，用户决定调整数量/方向或继续，不自动换路线无限跑。人数按本次必要条件统计，不等于有效客户或成交数。修改标准后旧结果保留但不计当前达标，数量单独修改可复用已判断资料。
+
+v0.3由 `delivery.py` 与 `people.py` 统一交付和人数口径：运行状态、目标满足、文件产物分别计算，保留原浏览器失败与停止原因。可选字段缺失不阻止交付；用户明确要求的本人需求、地区、可见账号号和CSV才成为必要条件。地区须本人该来源原话支持，IP或父评论不能代填。有限范围需实际成功采集、逐来源判断及覆盖依据，未取得资料不能称零需求。结果逐项展示需求、身份、地区、账号、跟进及可选用户后续反馈，补充来源/未知身份另列，不再统一要求人工待复核；CSV沿同一口径保留全部证据与缺项。
+
+## 2. 复用与重做
+
+复用 Electron/React 桌面壳、内嵌 WebContentsView、browser-use CDP 执行器、暂停/续跑/接管、逐步截图与进度记录、PostgreSQL 持久化、经验试用与回执数据结构。新增独立 `backend/prospecting/` 编排和 API；当前入口不挂载学校业务路由，不调用学校 NLU、填报或审批状态机。
+
+商家条件、拓客阶段、来源结果、业务判断与验收全部重做。原学校知识 YAML 仅作为历史资料保留；新运行只加载小红书拓客知识，使用独立租户作用域隔离旧学校任务和经验。兼容数据层的 `school_id/student_id` 暂保留为内部租户/操作者字段，界面不出现学校身份。
+
+## 3. 业务判断和证据
+
+- 商品/客户/地区按任务需要提取，不统一设为必填；关键词可由助手生成并在计划中说明推断。地区未提供即未知，不擅自补成全国。
+- 作者、首层评论者和每位回复者分别判断，保存父/根/回复对象关系；分享、教程和一般咨询不等于正在购买服务。“正在装修”与“明确找服务”作为不同判断维度，不能擅自缩窄目标。
+- 每条候选保留来源 URL、来源类型、原话、理由、观察时间；按已有证据具体说明字段状态，不自动确认客户身份或成交意向。
+- 名单与CSV共用按人分组，合并同人的全部原话、来源和纠正；身份待核记录另列。增量分析保留正文/父根上下文，按note_id或已观察笔记路径关联，不因临时签名链接变化丢失讨论背景。
+- 小红书阅读以实际页面为准，登录/验证码/访问限制暂停请用户处理；不把未读评论记为空，也不以搜索摘要代替已读笔记。
+- 来源完整 URL 由程序从当前页面读取，不要求模型寻找 canonical 或重建签名链接。先观察当前可见来源容器及原文，再逐条保存；候选容器仅来自当前真实 DOM。
+- 浏览器会话结束后，右侧切换为标明只读的最后截图及结束原因；不保留已销毁原生视图的空区域，也不把截图称为可操作网页。
+- 发现与整理不自动授权触达。关注/私信先只读核对账号与对象，再由用户选择具体批次；私信另需确定内容。实际动作必须使用受约束工具，核对发送账号、目标和输入内容，先持久记账再操作；已关注跳过，结果未知不重发。跟进执行配置关闭通用click/input/send_keys，避免绕过账本。
+- 私信出现红色失败标记或未知结果，持久暂停该账号后续私信；仅页面明确每日限制时标记当日上限。重新核对页面且无已知限制、用户明确确认后才解除，保留历史且不自动重放未知动作。此次开发没有对真实账号执行关注或私信。
+- 检索覆盖来自实际观察到的搜索页URL，分别记录已观察和未核对关键词；未核对范围不冒充已读。相同页面、相同动作且无新增来源连续重复时停止无进展操作。停止原因由程序记录，模型总结另存，不能用模型“预算耗尽”解释真实终态。
+- 已保存资料复核完成不等于网页采集完成。`done(success=False)`保留失败原因，复核同时检查原浏览器结果；旧误标任务通过只读投影展示阶段结果，原日志与数据库保留。检索覆盖接受实际观察到的`search_result_ai`路径并有限解码，不推断未观察的访问或全文阅读。
+
+## 4. 学习闭环
+
+操作能力、阶段模板、业务反馈与本次任务资料分层保存。阶段结束、暂停或异常后独立运行复盘；模型可提出探索候选，不能自报成功。`knowledge.py` 使用工作区隔离的 `prospecting_methods`、`prospecting_validation_events`、`prospecting_business_feedback` 保存方法版本、不可变事件和反馈；`verification.py` 将程序动作事实同步为方法及验收回执。旧通用经验表兼容保留，当前召回改用结构化方法，不再靠模型相符回执升级旧草稿。
+
+程序验收接保存独立来源、展开当前父讨论的新增回复、匹配来源作者的主页号及当前结果文件；只有完整前后引用、程序验证方式与实际后置条件才能计成功。无新增、加载慢、归属不明记未知；受阻、程序故障和未使用分别记录，不冒充方法反证。详细前后快照只保存在对应任务证据，共享事件保存引用和对象摘要。知识界面按原验证事件取对应动作前后快照，阶段证据不能用单一动作的快照替代。
+
+复用先检查平台、阶段、能力、来源类型、适配器版本、依赖版本及授权，再按独立证据和内部样本修正指标排序。首版至少3个独立任务、3个不同对象且没有未解决反证才进入优先复用；一次成功为可试用，无证据为探索候选。任务/对象最大独立匹配去重，同对象重试、恢复与重复导出不能抬分；修订以新事件关联原记录，依赖失效会重算阶段状态。高等级方法遇相关反证仍暂停。规则 `independent-evidence-v1` 是选择规则，不是成功/成交概率。
+
+当前参数化阶段仅验收同篇正文与一条独立评论/回复均保存的实际分支，依赖真实操作事件；没有把各动作拼成已验证的完整搜索/主页/触达链路。`xhs_visible_dom_v1` 是当前DOM适配器版本，不是平台所有页面变体分类，每次操作仍需现场入口与归属核对。更细页面变体、其他阶段组合及业务策略排名继续待真实样本积累。
+
+2026-10-29 首个新版真实任务审计（D37）：正文保存及CSV导出各形成1次有程序依据的独立成功，两方法均可试用；本次召回为空，尚未证明跨任务复用。评论/回复/主页链路未跑通。实际长句还暴露人数识别、账号可选及明确需求条件的程序提取缺陷，悬浮卡反复点击与8次动作结构错误导致部分交付；新建内嵌会话分支漏传目标版本，不能回填历史猜值。这些为当时待修问题，优先修复并沿原任务小范围验收，再继续不同对象的复用测试。
+
+同日D38已实现上述首轮修复并通过本地回归：长修饰语的人数绑定到候选对象，跨逗号可选账号不变必填、明确需求单独校验；旧任务仅在用户明确继续时按原话重核编译字段，保留后确认人数及原证据/文件版本。评论未进视口有明确状态，新增受约束的 `advance_comments` 原生点击/滚动及 `open_source_profile` 来源作者入口；重核稳定评论ID、原话与真实唯一链接，悬浮卡原地无推进不能反复点，不猜URL。导航观察仅留任务事实，不直接新增方法成功。
+
+无进展保护按页面、操作目标与真实新增累计，临时节点索引、悬浮卡、等待、空滚动、失败导航或未知展开日志不能清零；真实页面/滚动/来源变化才算推进。Schema失败仅记录程序声明字段路径和标准错误类型，供正常下一步纠正，不额外调用修复模型；连续失败保留程序原因，401/402/429保留实际具体类别。新内嵌会话也传目标版本，旧缺失不回填。知识页区分本阶段不适用与相关反证暂停，不显示跨阶段的误导性零成功。真实平台兼容和复用仍需下一次已授权任务验收，不能由本地夹具直接判为已修通整链路。
+
+同日D39只读复查用户已续跑的原任务：条件已按原话修正为CSV及本人明确需求，保留用户后来确认的1位，目标版本3；新增1篇有实际作者主页锚点关联的需求正文后，程序以 `target_reached` 在1/1停止并交付。当前2条正文中1位达标、1组身份未知，CSV保留两者。任务内召回正文保存方法，并新增具有目标版本及可读取前后快照的保存/导出事件；这仍是同任务续跑，两方法各只有1个独立成功任务，不算跨任务复用。评论、回复展开及完整主页打开均未执行：正文先达目标，不能据此称评论/主页新工具已通过真实验收。下一次验证应给指定笔记及有限讨论阅读范围，避免候选人数达标提前结束这一专项检查。
+
+同日D40按用户授权由CUA新建有限只读验证任务：指定1篇笔记、inspect、评论与回复合计最多8条，不继承候选人数；实际取得正文1、评论5、回复3，无触达。回复的父根及回复对象字段为空，3次回复操作验收正确保持unknown；无专用展开调用或展开事件，不能判完整讨论链路通过。当前completed对用户明确的展开及归属要求表达过强：先修回复归属，再补范围完成校验，随后重做同类有限验证；旧来源不补造父根。已观察到正文方法在新任务召回并再次执行，保持trial，不把同篇对象重查当作新对象覆盖。原生浅色左标题栏已取得真实截图，窗口按钮仅AX存在、像素未核实，拖动及全屏仍未验收；运行与结束按钮标签切换已在真实任务核对，持续旋转像素仍沿用隔离验证范围。
+
+同日D41已修复正文候选与保存观察对`.content > .note-text`的定位差异，支持明确讨论组内根评论与回复列表为兄弟节点的结构；平级回复存在明确回复对象但缺少唯一评论引用时，只确认根讨论、保留直接父评论未知。展开入口按当前真实讨论组观察，支持div文字入口、已渲染但未进入视口的定位及白名单筛选计数；按实际位置先推进视口，使用专用展开工具核对同组完整前后回复集合，不能由5条取证批量或其他讨论新增冒充展开。指定页面的inspect/research任务仅从用户直接要求提取评论、回复、展开及关系条件，缺项时交付阶段成果；阅读上限不当作最低条数，不由模型done宣告全部完成。两次同组有限实测均取得正文1、评论1、回复1，根关联已恢复；第二次专用展开有同owner新增1条及完整快照的程序成功，直接父评论仍未知。真实合法摘录与展开全文指纹存在严格匹配假阴性，离线精确核对已确认该新增摘录，但程序归属修复的最终状态见D41记录；不补写历史来源或事件，不据此升级整链路。现已增加程序观察的完整容器规范指纹：保存原话校验与展开后新增容器采用相同规范，按当前目标版本及真实保存事实绑定合法摘录；额外只读观察失败保留未知，不重试点击或模型。1017项本地回归通过，未补旧指纹、未启动第三轮付费任务。后续正常任务验证新绑定和直接父评论与回复对象；无须为凑成功重复运行相同范围。浅色左标题及原生三个窗口按钮已取得真实截图，拖动和全屏仍未测试。
+
+同日D42继续修复实际目标头部/标记/主页身份与同组唯一父回复的核对，缺唯一依据或冲突仍未知。新增真实用户会话驱动的第一组/一组范围，在检查与保存两侧约束根key，续跑只刷新正式请求及目标版本，不覆盖未落盘证据；归属要求支持完整回复链及直接父回复等自然说法，显式回复父回复的新增子回复另有独立深度条件，不能用根→直接回复代替。浏览器paint/hit测试核对当前可命中点后使用原生mouse，不按旧坐标盲点。`resolve_reply_target`从实际前缀入口原生移入，重新核对来源及命中点后单击；只有真实主页身份、原生返回及原来源重新核对都成立，才以本轮短期依据匹配同组唯一父回复，同作者多条发言仍未知。宿主仅允许页面实际触发的小红书HTTPS主页弹窗在同一视图打开，诊断只保留白名单分类和动作，不拼URL。
+
+DeepSeek浏览器适配改为标准端点强制命名函数提交完整输出并本地校验，保留图像、usage及关闭思考；结构拒绝内部422，安全纠错提示随正常下一步，不增独立修复调用。D42两任务及同篇续跑累计111次实际调用，110次成功、1次连接错误、Schema错误0；未知连接原因和未返回usage不推断为格式、欠费或零消耗。工程上全后端1209项、Node弹窗11项、TypeScript及桌面构建通过；真实业务上明确组范围、专用同组展开及容器绑定取得验证，但目标子回复仍为直接父未知，关系3/4、二级分支0/1。手动实际作者头部链接可打开完整主页，回复前缀点击仍无导航或弹窗，返回未成功；不能用作者主页替代回复目标身份或宣称整链路通过。目标版本2追加网页回查误走已有来源分析，现已按真实追加指令在意图落地、准备与执行处纠正：明确网页核对优先进入浏览器，已保存/不新增来源只限制范围；纯离线复核仍复用。回查从当前页与原生历史起步，明确禁止分析时保留旧判断及版本，不增加收尾分析调用。该路由修复通过本地回归，尚无修正后的实页回执。旧目标展开不能计入新目标，交付继续partial；同篇续跑不增加独立对象排名。详细实测、用量及资料完整性见D42记录。官方协议依据：[Tool Calls](https://api-docs.deepseek.com/zh-cn/guides/tool_calls/)、[Chat Completions](https://api-docs.deepseek.com/zh-cn/api/create-chat-completion/)。
+
+同日D43本人登录后，在新笔记做首组只读验收。首个当前页续跑曾误导航应用UI，后增加task→view→target锁、上下文和逐act状态边界及显式当前页修订时的view保护；丢失或错误业务目标不猜地址恢复。标准JSON Schema导出补minItems与单动作项属性数约束，仍完整校验，不修坏JSON或补动作。1251项后端、TypeScript、构建及Node弹窗11项通过；保留liveview的修订竞态仅有本地回归，不用显式入口的实页结果替代。初始目标版本1候选浏览最多2篇，版本2/3明确只当前新笔记第一组，范围为正文最多1条、评论与回复合计最多4条；三版属于同一任务，不按修订次数加独立分。最终目标版本3实测正确新业务页、正文1/评论1/回复2、专用同组展开新增2和规范容器绑定、无名单分析或触达；首条普通回复父根正确，明确二级子回复仍只有根讨论和可见目标文字，无唯一目标主页身份，实际目标点击not_moved，主页返回重核未验。当前UI为4条阶段资料、部分交付，关系1/2、二级0/1。整任务25调用含早期1结构拒绝，最后13调用零结构错误，不称全轮零错误。正文方法有3独立任务/3对象而进入preferred，其它相关操作2/2仍trial、阶段链paused；新笔记不等于二级身份已可核对，不为凑通过追加同类付费续跑。
+
+同日D44开始将样本预检与取证分开：`inspect_reply_relations`只读当前可见组，只有稳定且唯一的直接父为另一条回复才为eligible；需要原生身份、冲突和未知均不合格，预检不自动展开、保存、打开目标或形成方法成功。首个有限任务13次调用全部成功，但实际打开两篇新笔记及一篇排除旧笔记，且预检原始计数未持久化，不能认可严格范围或把模型报告的0/0当程序验收。随后增加独立安全预检遥测、当前run/目标版本的实际访问gate及预检专属交付：确认可见且范围完整时，零合格也可作为“预检完成，未发现合格样本”；未到视口、访问记录缺失、越界或未知继续保留限制，不能假称读完。纯预检应跳过保存方法召回、名单分析及知识成功验收。第二个独立任务6次调用全部成功，程序确有0/0未到视口及1/0未知的遥测，实际仅一篇指定笔记、无保存或触达；但“独立做一轮只读预检”未被策略解析识别，访问gate、专属交付及知识过滤未启用，仍落到普通无来源blocked。1400项后端、TypeScript、构建及4项SSR检查是该修正阶段的本机结果，不能覆盖真实措辞漏识别。正在补实际原话回归；第三次独立实测前先离线确认active、最多1篇及排除2篇，不改写前两个任务的失败、用量或知识事件。二级归属与跨任务方法执行仍待真正合格样本，不用预检计数代替成功事实。
+
+个人昵称、评论原话、用户资料和临时搜索词不作为跨任务操作经验。只召回当前小红书作用域，旧学校知识不注入。👍/👎关联任务、结果快照和目标版本，单条纠正保留原证据；方法反馈独立提交，不改写任务目标或重跑浏览器。用户可选记录已回复/确认需求/合作/无回复/不匹配，明确标为用户反馈、归因未证实；满意度和业务结果不增加方法技术成功数。替代路线按已有成果提供：复核已保存资料只调用独立分析，不新增网页操作；导出生成本地名单。路线提交校验当前目标与结果版本，保留账号暂停及未知动作记录。尚无真实获客效果排名。
+
+2026-10-29 对最近跟妆任务只读审计：任务保存正文/评论/回复3类取证操作草稿，共享库只有1条draft、0条verified，试用回执0；当前任务未召回旧经验。这些草稿只覆盖可见容器检查和原话保存，尚不包含已验证的完整搜索、详情、展开回复、主页及交付链路。历史通用文本判重把相似的三类模板误合并，旧采集空快照还可能覆盖复盘后候选列表。
+
+后续程序操作合同使用 `xhs_operation_{capability}_{source_kind}_v{version}` 稳定身份，在本小红书作用域按能力、来源类型和版本区分，独立于历史 `xhs_visible_*`；同合同重复复盘不重复累计观察。本轮有真实来源依据的合同内容由程序生成，不能被模型同key候选覆盖。恢复学习候选和回执保留数据库与快照两边的独有项，冲突保留数据库主值并留下双方依据，不把冲突重复算成多次验证。历史错配行保留审计，不自动修写或升为verified；实际可复用性仍须下一次不同对象的真实任务产生逐条回执。
+
+界面投影由 `backend/prospecting/cards.py` 从任务与实际证据生成，前端仅渲染固定卡片。界面、路线和导出使用同一恢复后的来源版本；来源和主页按来源ID合并，较新观察优先，未知或相同时间保留数据库记录。导出使用独立文件清单保存版本与时间，不被后续旧任务快照抹去；文件缺失或路径不属于任务目录时不能打开。
+
+## 5. 模型和公开资料工具
+
+2026-10-28 核实官方文档：默认 `deepseek-flash`（DeepSeek-V4.1-Flash-1017，支持图像输入），可选 `deepseek-v4-pro`（文本复核，当前不支持图像）。保持 browser-use 锁定 0.13.10，按该版本实际接口适配截图和结构化输出；不无依据升级整个执行框架。
+
+DeepSeek Search/Fetch 作为可选公开网页工具，使用相同 DeepSeek Key；Search 搜索公开材料、Fetch 返回 Markdown。此工具不复用小红书登录态，不保证可读登录后正文或评论，不将第三方摘要升级为已验证线索。默认不开启，用户显式选择或主动使用资料检索入口才调用。
+
+**后续讨论事项（2026-10-29，用户要求先记录、暂不实施）**：当前Search会保存公开检索结果，Fetch已有独立API，但公开资料尚未接入关键词优化和后续任务规划，开关的实际辅助价值有限。后续讨论按需接成“检索业务背景 → 阅读公开正文 → 展示来源与依据 → 优化搜索方向 → 到实际小红书页面核验”。先跑稳小红书主链路，再讨论启用时机、资料展示、效果验证和复用方式；不把公开摘要混入实际读取的客户证据，不自动启用或立即扩展功能。
+
+**用量与重复调用优化（2026-10-29 已实现）**：保持deepseek-flash和关闭思考。在供应商响应返回时、结构校验前记录实际usage，按任务及意图/网页/上下文整理/增量分析/复核阶段累计模型、输入输出、缓存及校验状态；旧历史缺项、未知/部分用量与存储异常单独展示，不推算为0、不当供应商费用账单，也不建立自有余额或用量配额。日志不保存Key、原始提示/响应或签名链接。存储异常不触发模型重试。
+
+相同来源、标准和模型复用已核验判断，只分析新增/变化资料；正文/父根、纠正、业务标准或模型变化会令相关缓存失效。普通资料复核优先复用，另设“重新分析（新增模型用量）”明确强制重做。过程输出要求简短；同一笔记、同一已保存来源量下三次容器/原文取证失败，当步停止并保留资料，不继续付费空转。这里是无进展保护，非任务总量配额。实际节省费用及真实平台表现待后续任务对照验证，旧任务用量无法补造。
+
+官方依据：[模型](https://api-docs.deepseek.com/zh-cn/quick_start/pricing/) / [视觉](https://api-docs.deepseek.com/zh-cn/guides/vision/) / [Search/Fetch](https://api-docs.deepseek.com/zh-cn/guides/search/)。
+
+## 6. 运行与验证
+
+当前目录保留 `school-assistant/` 名称，应用显示“橘子拓客”。独立 PostgreSQL 使用原端口 15433，不触碰同级 assistant 的库、浏览器登录态或服务。启动前检查端口归属，不关闭其他项目的进程。
+
+先验证依赖、类型/构建、后端测试和本地完整流程，再启动桌面应用。缺 Key 时界面可运行并明确提示未配置；真实模型、Search/Fetch 和小红书登录后链路分别验证，不用本地夹具代替真实成功。
+
+## 7. 当前实施顺序
+
+本轮已实现以上对话、阅读、导出、授权、反馈及复盘合同，并完成本地测试和桌面启动核对。旧任务59/60步与51/60步、已保存来源和失败历史各自保留，未自动续跑或追加真实平台采集。
+
+当前顺序以用户纠偏阶段为准，各阶段汇报后须获监督确认才进入下一阶段：
+
+1. P0冻结止损：默认关闭实验工具与全部预检路径、保存成功与父关系分离；不继续D44桌面复测。本机验证完成，P1首轮44个真实浏览模型请求已补齐工具列表回执。
+2. P1主链路基线：用户已确认装修服务及近期准备装修用户，真实只读discover目标10位、不加篇数上限，实际2/10位后按原取证停滞规则停止。任务目录已输出 `baseline.json`，完整指标见当前P1记录；未达标缺8位，不调参凑数、不续跑美化基线。测量阶段完成，业务未达标，等待监督确认后进入P2。
+3. P2确定性动作程序化：按实测瓶颈实现 `harvest_note(max_items)`、`list_search_notes(keyword)`，保留原话校验及去重；与P1同任务规模对比单候选调用及token下降至少50%，用数据评估非判断步骤关闭视觉。
+4. P3用可执行工具序列及参数沉淀流程，真实台账填成本，同类第二任务衡量节省量；保留 `independent-evidence-v1`，停止未验证方法的浏览器提示注入。
+5. P4模型结构化提取、理解卡确认后程序执行；盘点并替换直接改意图/范围的自然语言正则，正则只作确认提示。P5在P2完成后按职责纯搬移tools，归档D20–D44并将主PROGRESS控制在200行内；P0不提前拆分或归档。
+
+同一做法失败两次即停下查根因换思路；登录、验证码、平台限制、余额或鉴权问题立即暂停并如实报告。真实触达及任何提交代码须另获用户明确同意，当前不commit/push。未授权关注、评论、私信的边界、四个独立端口及内嵌park约定保持。
+
+细粒度JSON错误诊断等未单独验收的事项继续保留，不用本次UI更新替代。截图连续稳定性按后续真实批次记录，不从本地夹具推出全局保证。
+
+每轮按“问题出在哪 → 怎么修复及验证结果 → 接下来怎么走”收尾，保留未解决事项，具体约定见项目 CLAUDE.md。

+# 对照：同事的 PenguinUniOS（D:\qiekj\agent-a2a）
+
+> 2026-09-17 调研。同一公司同类产品的另一条实现路线，用来对齐桌面端形态、借鉴工程做法。不是要照搬全部。
+
+## 1. 它是什么
+
+三端 monorepo（npm workspaces，Node 24，uv 管 Python 3.12）：
+
+| 端 | 栈 | 职责 |
+|---|---|---|
+| apps/learning 学习端 | FastAPI + React/TS/Vite；SQLite（documents JSON 表）+ PostgreSQL 17（知识）；Playwright + 自研观察 JS | 探索学校系统 → 证据 → 模型评判 / 人审 → Ed25519 签名发布「能力包」（form-v1 等） |
+| apps/desktop 桌面端 | Electron 44 + React 19 + TS；Vite / esbuild；两个 uv 虚拟环境的 Python worker 用 PyInstaller 冻结随包分发，stdio JSONL 通信 | 无登录聊天、多模型、消费学习端发布的能力、`WebContentsView` 内嵌浏览器、密码管理、编排调试 |
+| apps/admin 管理端 | FastAPI + React/TS + Ant Design 6；PostgreSQL（16 表）；scrypt 口令、Fernet 密钥指纹 | 学校、成员、账号角色、模型连接、桌面接入 Token、审计 |
+| packages/contracts | Pydantic 单源 → 生成 TS + JSON Schema，CI 带 --check | 三端 DTO |
+| specs/ | 78 个带日期编号的中文规格 | 每个行为 / 协议变化先改规格 |
+
+## 2. 桌面端长什么样
+
+- ChatGPT 式浅色工作台。左侧 296px 侧栏：品牌、新建对话、历史搜索（置顶 / 归档 / 重命名 / 删除确认）、密码管理、模型选择、底部身份。顶栏：对话标题 + 菜单，「浏览器 / 导出 / 复制」。中间消息流最大宽 800px，欢迎页给目标入口；输入框带加号上传、模式胶囊、停止 / 发送。
+- **右侧浏览器面板**：打开时占 384px 到 40%。工具栏显示标题、地址、「暂停 / 接管浏览器 / 继续 / 收起」。实现：主进程 `WebContentsView` 挂到主窗口 `contentView`，渲染层 `BrowserPanel.tsx` 用 ResizeObserver 量出占位 div 的位置，经 IPC 让主进程 `setBounds`；用户在面板里点键盘或鼠标时主进程拦截输入并自动进入接管。
+- 任务卡挂在消息流里：状态标签（排队中 / 正在理解目标 / 等待补充信息 / 等待原页登录 / 正在办理 / 已填写尚未提交 / 已暂停 / 原网页填写中 / 正在核验结果 / 核验完成 / 办理未完成 / 结果待核实 / 已取消）、目标、Agent 控制状态、事件时间线、带选项的追问表单（单选 + 自填，Enter 发送且中文输入法合成期间不发）、回执、动作按钮。
+- 视觉规范（`docs/standards/FRONTEND.md`）：不用渐变 / 阴影 / Emoji 图标；Lucide 图标；PC 间距 8px 倍数、正文 14px；颜色圆角走设计变量（白底、#f7f7f7 侧栏、黑色 accent、16px 圆角）。
+- 执行模型：DOM 观察与动作在 Electron 主进程自研，browser-use 0.13.10 只调 `Agent.get_model_output()` 做单步决策；每步绑定观察版本，单次提交窗口，提交后独立核验，结果未知进 uncertain 不自动重试。
+
+## 3. 和我们的差别
+
+| 维度 | 我们 | 他们 |
+|---|---|---|
+| 执行 | browser-use `Agent.run()` 全程自主 + YAML 业务 + learned 注入 + 确认卡片 | 自研执行器逐步严格校验，模型只在枚举动作里选；能力由学习端先编译再发布 |
+| 知识 | YAML 出厂 + 运行中自动沉淀 learned（内容判重、自动晋升） | 学习端探索 → 证据 → 评判 → 签名发布 form-v1；桌面只消费 |
+| 浏览器 | 独立 Chrome 停靠 + CDP 收起展开 | `WebContentsView` 真正内嵌 |
+| 数据 | MySQL（Docker） | 学习端 SQLite+PG，管理端 PG |
+| 身份 | 单机 default 用户，密码本人×系统带角色 | 三端各自认证，统一身份 C1 只有设计 |
+| 桌面栈 | Electron + 原生 JS | Electron + React/TS/Vite，PyInstaller 打包 |
+| 文档 | CLAUDE / DESIGN / PROGRESS | AGENTS / specs 编号 / VALIDATION 记录，「禁止虚报」写进规范 |
+
+两条路线各有道理：他们控制力和审计更强，工程量大得多，且依赖学习端先把能力编译好；我们上手快、靠 learned 越用越快，但对陌生控件和异常页面的稳定性依赖模型。中期可以走混合：稳定业务编译成确定性流程（他们 form-v1 的思路），陌生 / 第三方系统用我们的 Agent 路线。
+
+## 4. 值得借鉴（按价值）
+
+1. **桌面端形态与栈**：React/TS/Vite、`WebContentsView` 内嵌浏览器、任务卡与追问表单结构、状态词汇、视觉规范、Lucide 图标。→ 我们的渲染层按此重做（DESIGN 第 8 节新增第 14 项）。
+2. **打包链**：uv 虚拟环境 + PyInstaller onedir 冻结 Python worker + electron-builder extraResources。→ 解决我们「学校用户装不了」。
+3. **契约单源**：Pydantic → TS/JSON Schema，CI 校验。→ 渲染层改 TS 时顺手做。
+4. **提交结果未知不重试**：`uncertain` 状态、证据不可覆写、pending 不自动重放。→ 我们提交类步骤补 uncertain 分支。
+5. **管理端模板**：FastAPI 工厂 + PG + Ant Design 6 + scrypt + Fernet 指纹 + 手工 DDL 三重 guard + 每校独立密钥。→ 我们的后台 / 服务端层直接参照，甚至复用其 schools / members / accounts / audit / provider_connections 表。
+6. **「禁止虚报」与验收记录**：每个 spec 区分已实现 / 待验收 / 不能据此声称。→ 我们 PROGRESS 已接近，再严一点。
+7. 规格编号即变更日志；每校独立签名密钥，平台密钥不进交付包。
+
+## 5. 不建议现在照搬
+
+- 学习端整套编译发布链（探索 → 证据 → 评判 → 签名）：太重，且他们自己的漂移自动失效、自动补学、SQLite → PG 迁移都还没闭环。
+- documents JSON 单表设计。
+- 他们的统一身份（未实现）、租户计费（延后）、达梦支持（未实现）。
+
+## 6. 待你们决定
+
+1. 桌面端按第 2 节重做渲染层，同时对齐打包链？
+2. 数据库要不要从 MySQL 换成 PostgreSQL，与管理端一致（现在切代价最低：只有 PyMySQL 一层）。
+3. 仓库关系：继续独立仓库但对齐规范，还是将来合入 agent-a2a 作为一个 app？合入则要遵守其 `docs/standards/GIT.md`（逐文件暂存、Conventional Commit、不建分支）。
+4. 执行路线：近期保持 browser-use `run()` + learned；中期是否引入「稳定业务编译成确定性流程」的混合模式。

+# 小鹅参考界面与拓客桌面实现
+
+参考：[小鹅 全天候为你服务](https://school.miaopinai.com:29800/team-work/penguin-world/pages/a9030e2b-ec1a-4a88-b6b4-1faaccb52c1f)。用户要求复刻视觉及动态，业务继续采用本项目的拓客流程。
+
+## 实际观察范围
+
+参考内容位于 Penguin 页面的 iframe 内。已从加载后的内页读取布局、控件、计算样式、品牌 SVG 和方阵动画关键帧，并查看实际截图。桌面以主助手界面为基础，页面下方的校园演示场景用于观察任务过程的表现方式。
+
+## 布局与视觉
+
+| 项目 | 参考测得的值 | 桌面实现 |
+| --- | --- | --- |
+| 主面板 | 浅蓝灰 rgb245,248,252，22px 圆角，细描边与柔和阴影 | 单段持续对话，默认收起历史和执行页面 |
+| 文字 | 主色 rgb32,57,85；基础13px/19.5px；正文14px | 同色系，保留拓客名称与真实结果 |
+| 页眉 | 高100px；padding24px28px20px | 小鹅形标识、助手名称、对话记录和任务设置入口 |
+| 分隔区 | 高约51px，细线与很小的状态提示 | “一直在这里”及会话接续说明 |
+| 输入区 | padding8px28px15px，透明渐变承接内容 | 底部三个快捷入口、白色圆角输入框、蓝色向上发送按钮 |
+| 辅助面板 | 历史和任务/设置按需打开 | 可关闭抽屉、键盘焦点循环、Escape关闭；执行网页独立按需展开 |
+
+实际输入和结果仍来自本地后端。公开检索开关、连接状态、导出、评价和授权等使用真实功能；校园场景、模拟结果、未接入的语音和附件功能未作为拓客能力呈现。
+
+## 粒子与翻转动画
+
+小鹅点云按参考页实际 SVG 的 `126 94 348 252` 轮廓采样，包括翼、尾、喙、白色腹部与颈线，以及白脸中的深色眼睛。Canvas随真实任务的idle/running/paused/completed/error状态变化，不用动画产生完成结论或虚构进度。
+
+银蓝方阵采用观察到的10列布局、4.8秒周期和70ms对角错相，保留340px透视、细边框、正反面颜色和翻转中的窄反光。真实分析阶段显示方阵，真实结果返回后呈现结果内容，未增加人为等待时间。
+
+粒子轨迹使用本地Canvas实现；参考页原始粒子脚本的完整运动参数未取得，因此本版不能宣称粒子逐帧轨迹完全一致。形状、配色、布局及方阵关键帧已经按可观察依据对齐，后续可通过同尺寸连续画面对照继续调整。
+
+动画支持减少动态选项并尊重系统偏好。Canvas最高30fps、DPR不高于2；隐藏/离开可见区域暂停，卸载清理观察器与rAF。减少动态时保留静态造型。
+
+## 原生浏览器与验证
+
+抽屉和设置覆盖主界面时卸载浏览器占位，沿用窗内2px停放机制；恢复后重新测量真实位置。界面未通过transform移动原生浏览器区域，也未更改其登录态和执行能力。
+
+`npm run check`、`npm run build`、差异检查通过。隔离Electron界面42项检查通过，覆盖业务交互、抽屉焦点、原生视图停放/恢复消息、窄窗、状态切换和实际方阵动画。另验证五种粒子状态非空、两帧变化、减少动态后静止、卸载无rAF遗留。
+
+验证材料位于 `data/ui-verification/blue-ui-fixture.json`、`particle-companion-fixture.json` 及对应截图。所有业务数据为本地夹具，本轮没有真实模型调用、平台采集或对外触达。
+
+## 下方场景与拓客卡片适配建议
+
+2026年10月29日继续查看下方场景。人事材料整理演示先用对话确认“本月新入职材料”和缺项如何处理，执行时在任务卡更新工具返回，交付时在同卡显示2/3已备齐、1项待补充、材料清单、后续待办和依据。图书馆场景在原卡显示实时返回及“正在组装结果”；访客和报修示例通过对话补齐离校时间、联系人等当前缺项。这些都是参考页的模拟场景，不能作为本项目真实能力或业务结果。
+
+本次确认了对话、执行和交付内容，尚未逐一验证14个场景里每种补充表单的输入、校验、修订和提交状态。
+
+当前拓客界面的计划卡仅展示`missing`文字，并让用户回主输入框补充；还没有通用的字段级补充卡。跟进授权、评价和单条纠正已有小表单，执行进展和导出已有数据，但还没有统一为完整的场景卡片机制。此前42项检查只覆盖已实现界面行为。
+
+| 场景卡片 | 拓客中的适配 | 展示条件 |
+| --- | --- | --- |
+| 必要信息补充卡 | 只补会影响当下动作的业务背景、匹配口径或话术等 | 已有信息自动带入；信息足够直接推进，不恢复固定前置表单 |
+| 来源核验卡 | 本人原话、来源、主页身份，以及地区等已确认/待核事项 | 不把未知字段填成确定值，也不把父评论信息传给回复者 |
+| 阶段执行卡 | 搜索、展开回复、核对主页、分析的真实进展及卡点 | 新增证据和后台事件驱动更新，不以计时动画模拟执行 |
+| 跟进确认卡 | 当前账号、目标范围、关注动作或确定的私信内容 | 承接明确授权，只补缺失或变化项，不逐人重复索取相同信息 |
+| 名单交付卡 | 表格、筛选、来源证据、待核项及可重新打开的导出文件 | 沿当前任务原地交付并保留历史，不另起空任务 |
+| 受限恢复卡 | 原因、已完成/未知/未执行状态、适用的独立替代路线 | 选择路线必须连接真实动作；私信受限不转其他入口继续发送 |
+
+这些是待适配建议，本轮未修改运行逻辑。建议先定义受控卡片合同：稳定字段ID、问题ID、必要性、预填值、允许选项、校验、目标版本和有效状态；前端使用固定组件渲染，模型只填允许的数据。旧卡随目标修订失效，用户可用小卡或自然语言回答同一个问题，完成后沿原任务继续。
+
+已识别具体缺口：后端替代路线返回`id/title/reason/deliverable/status`，前端仅在有`message/prompt`时显示选择按钮，当前路线大多仍是文字建议。后续需把路线ID与实际核验/导出动作接通，并展示预期产物。
+
+## 第二轮场景适配
+
+2026年10月29日用户批准方案后，新增独立流动对话粒子，空闲保留品牌企鹅，执行时粒子缩为角标，分析使用任务卡内方阵。等待补充、暂停和受限停止工作动画；历史打开不重播结果组装。对话粒子是当前本地实现，尚未取得参考页原始运动轨迹，不称逐帧复刻。
+
+补充卡使用固定字段与版本校验，卡片或文字回答均沿原任务继续，已回答和被更新的卡保留只读记录。阶段卡读取实际事件、来源及覆盖，不使用虚构百分比；没有实际记录时不显示空统计。名单采用可筛选表格、单人来源核验和纠正，文件卡保留历史版本、生成时间及可用状态。复核和导出路线已接真实API，受限不会自动转入口继续发送。
+
+本地 CUA 已实际操作补充、字段校验、失败草稿、筛选、来源、纠正、导出重开、评价和路线；检查历史静态、停止后无工作粒子、600px窄窗无横向溢出。执行角标两帧截图区域变化1602像素，减少动态后的同一区域变化0像素。纯调度器另有8项可复现检查，命令 `node scripts/check-particle-loop.mjs`。本轮无真实平台或模型调用，截图中的夹具数据均有明确标识。

+# AI 拓客助手 UI 优化方案
+
+2026年10月29日，用户已批准并完成首轮实施。本地交互与工程验证见 PROGRESS 的 D30；精确粒子运动仍需参考连续画面对照。
+
+桌面继续沿用参考页的蓝灰玻璃视觉和单段持续对话。此次重点是把默认企鹅粒子、对话粒子、结果组装动画分开，并让补充信息、网页执行、线索核验和交付各有合适的卡片。用户说一句话即可开始，信息足够就执行，必要时才出现补充卡。
+
+参考：[小鹅页面](https://school.miaopinai.com:29800/team-work/penguin-world/pages/a9030e2b-ec1a-4a88-b6b4-1faaccb52c1f)。参考页场景为模拟演示；本项目的状态、数字和动作回执必须来自真实执行。
+
+## 当前缺口
+
+当前 `ParticleCompanion` 的待机、执行、暂停、完成和异常都使用同一品牌轮廓，主要改变漂移和透明度；只有分析阶段切换方阵。这使默认展示和对话反馈的区别不明显。补充信息仍主要展示文字，缺少统一的字段卡；替代路线多数也只展示建议，没有接通后续动作。
+
+参考页已经核对人事材料清单、图书馆实时返回及组装、访客和报修的对话补充等表现。全部14个场景的表单校验尚未逐项验证；对话粒子的精确轨迹和节奏应在实施前通过连续画面定稿。
+
+## 页面布局
+
+保留顶部品牌、历史和设置入口，底部固定输入区。中间是一段可回看的对话，任务卡随执行在原位置更新。默认不打开固定侧栏和网页面板；用户需要查看或接管时展开实际网页。
+
+首次进入或当前没有活动任务时，中央展示现在的企鹅造型粒子、简短状态和三个业务入口：找潜在客户、整理已有线索、继续上次任务。入口填入自然语言或打开已有任务；仅在存在可继续任务时提供继续操作。
+
+进入任务后，对话和卡片成为主体。大粒子让出空间，对话粒子放在最新回复附近。交付后保留结果，默认企鹅可在当前状态区域小幅展示，不把结果挤出视野。滚动查看旧消息时不强行拉到底部，只提示“有新进展”。
+
+## 三类动画与切换规则
+
+| 时机 | 动画与位置 | 退出条件 |
+| --- | --- | --- |
+| 初次进入、没有待处理请求 | 默认企鹅造型，低幅呼吸与轻漂移 | 用户提交委托 |
+| 理解委托、组织最新回复 | 独立对话粒子，参照场景对话中的聚散流动形态 | 回复或补充卡可显示时立即结束 |
+| 等待用户补充或确认 | 信息卡突出；粒子静止或极弱动态 | 用户回答，或取消当前请求 |
+| 浏览器执行任务 | 阶段卡为主，对话粒子缩为小型活动标记 | 阶段结束、暂停或受限 |
+| 分析证据、准备结构化结果 | 当前任务卡内出现银蓝方阵翻转与组装 | 真实内容到达即展示 |
+| 正常交付 | 内容短暂淡入一次，工作动画停止 | 保留静态结果及下一步操作 |
+| 登录、平台受限、结果未知或错误 | 停止工作动画，突出实际原因与可选操作 | 问题处理且任务实际恢复 |
+| 用户浏览历史 | 静态快照 | 只有实际续跑才重新启动活动动画 |
+
+默认企鹅和对话粒子使用不同的形态与运动设计，不能仅靠加快同一个造型表达。切换采用短暂聚散或淡入淡出，第一版建议约200至350毫秒，最终以参考连续画面校准。结果不等待动画播完，长任务也不靠动画假装有新进展。
+
+同一时刻只有最新活动卡播放主要动画。暂停工作动画与取消后端任务分别处理，视觉不会替用户中止任务。减少动态模式用静态造型和文字提供完整信息；隐藏页面停止绘制，恢复时读当前状态。
+
+## 业务卡片与参考场景适配
+
+| 参考表现 | 拓客中的卡片 | 主要内容与操作 |
+| --- | --- | --- |
+| 访客、借阅等对话补齐必要信息 | 必要补充卡 | 只问影响当前动作的缺项；已给信息预填，支持卡内回答或继续说话 |
+| 批量审批的分组与确认 | 计划与范围卡 | 当前理解、匹配口径、搜索方向、计划阶段；可修订，信息齐全的只读任务无需额外确认 |
+| 网页办理的实时返回 | 阶段执行卡 | 当前阶段、最近实际动作、新增来源、覆盖和卡点；详情折叠，支持查看网页、暂停和接管 |
+| 人事、学工、职称等核验清单 | 线索核验卡 | 本人原话、来源、主页账号及待核字段；区分已确认与未知，支持单条纠正 |
+| 门户、教学等工作清单 | 名单与文件交付卡 | 表格预览、筛选、来源、待核项、导出文件和本次新增量；历史中可重新打开 |
+| 知识问答的依据展示 | 资料与依据卡 | 带来源的回答，区分公开资料与实际平台取证；公开检索沿用显式启用条件 |
+| 公文草稿、批量动作回执 | 跟进卡与回执卡 | 目标批次、当前账号、动作、确定话术，以及成功、失败、未知、未执行；沿用明确授权 |
+| 预警、实习等后续工作 | 受限恢复与后续建议卡 | 说明原因，保留成果，提供可执行的独立路线；建议不自动变成提醒或触达 |
+
+每张卡共用轻量外框：任务名称、阶段状态、主体内容、依据和下一步。具体主体使用清单、表格、文本字段或回执，不让所有业务都挤进同一种大表单。
+
+### 必要补充
+
+“帮我拓客”缺少足够业务背景时，先问清服务和想找的人。用户已经说“我做杭州装修，帮我找最近在装修的人，把账号整理给我”，就提取现有条件并推进，不再次索取产品、地区、关键词和阅读数量。地区只有影响当前匹配时才成为必要项，关键词由助手生成并解释。
+
+补充卡支持短文本、长文本、单选、多选和具体对象选择，按缺项使用。提交失败保留草稿，字段就地提示问题。用户用自然语言回答后，对应卡同步完成；目标改变时旧卡标为已更新，不能再提交。
+
+沿用无默认篇数、评论数和总步数业务配额，也不增加自建余额限制；用户明确数量时才显示相应范围，真实上游或平台限制单独说明。
+
+### 执行与核验
+
+阶段按本次计划展示，例如搜索、读正文及回复、核对主页、分析、整理名单；未要求的阶段不默认加入。显示真实新增来源和实际覆盖，不显示没有可信分母的完成百分比。
+
+核验卡借鉴材料清单的“齐备与缺项”：小红书号已核对、地区未知、需求需要进一步确认等分别呈现。回复者保持自己的身份和原话，不能继承父评论信息。卡片中的数字来自当前结果快照，待核线索不称为已成交客户。
+
+### 交付与后续
+
+名单卡先展示可读表格，再按需打开证据详情。未知的小红书号留空并标待核；导出完成后显示真实文件入口、格式和生成时间。数据有新版本时区分旧文件和当前结果，不把旧文件当作最新名单。
+
+阶段完成、部分交付、用户停止、平台受限和技术异常分别表述。受限卡说明哪些已完成、哪些未知、哪些尚未执行；路线按钮连接实际阶段，例如核验已保存线索或导出当前名单。私信失败时暂停账号后续私信，只有页面明确日限时才称当日上限，不能用换入口继续发送作为替代路线。
+
+交付下保留👍👎和可选原因，支持单条纠正。满意度、线索质量、真实回复或成交分别积累。经验只显示实际产生的状态，例如操作草稿、待跨任务验证、已验证适用条件；不会用点赞或漂亮动画直接宣布“学会了”。
+
+## 一次完整体验
+
+1. 首页显示默认企鹅。用户说：“我做杭州装修，帮我找最近在装修的人，把账号整理给我。”
+2. 最新消息旁出现对话粒子，助手提取目标并展示简短计划。信息足够直接开始，只读搜索不会自动包含关注或私信。
+3. 阶段卡更新实际搜索和阅读进展。用户可查看网页，或继续补充筛选要求；已有结果和任务历史保留。
+4. 整理时卡内出现方阵；结果一到即展示核验清单和名单，未知项标清，导出生成真实文件入口。
+5. 用户要求进一步跟进时，沿当前名单进入下一阶段，只补必要的对象范围、账号核对或话术。已有明确授权仅在账号、对象范围、动作和话术均未实质变化时沿用；发生实质变化时重新核对。目标修订后旧卡不可再次提交，授权是否仍适用由这些实际条件判断。
+6. 结束后停止工作动画，保留交付和评价。企鹅回到轻量待机状态，用户可以接着说下一件事。
+
+## 实施顺序
+
+第一步，定义统一状态与卡片数据，打通必要补充和原任务继续；同时分离默认企鹅与对话粒子，完成进入、等待、暂停、历史和收尾的切换。
+
+第二步，把真实阶段事件、来源核验和名单交付放进任务卡，接通导出文件和替代路线，保留既有授权、反馈和纠正行为。
+
+第三步，用参考页同尺寸连续画面对照密度、聚散、速度和过渡，再完成窄窗口、减少动态及键盘操作。原生浏览器区域不做变换；抽屉覆盖时继续使用既有停放和位置重测机制。
+
+## 验收条件
+
+- 默认企鹅与对话粒子一眼可区分；只在真实请求或执行期间出现工作动态，结果到达立即可读。
+- 一段自然语言能直接启动信息齐备的任务；缺一项只补一项，用卡片或文字均能沿原任务继续。
+- 同一个任务可经过补充、执行、核验、导出和评价；目标修订后旧补充和授权卡不可再次提交，来源和已执行记录保留，未变化的明确授权按原范围沿用。
+- 部分结果、登录等待、平台受限、失败和未知结果都有准确表现；替代路线可执行且不绕过原限制。
+- 返回历史不重播组装、不重复执行；滚动读历史不被拉走，导出入口可重新打开并标明版本。
+- 减少动态、隐藏暂停、卸载清理和窄窗操作正常；桌面原生浏览器的停放、恢复、截图及接管不受动画影响。
+
+先用隔离本地流程验收交互，再单独验证真实只读平台任务。UI 验收不替代真实关注、私信或获客效果的验证。

+# 智能办事助手：产品定义、架构与决策
+
+> 这份文档回答"我们在做什么、为什么这样做、接下来做什么"。里程碑和实测数据见 `PROGRESS.md`。
+> 每次做出新的设计决策，在「已定决策」追加一条并写日期；改变方向时改这里，不要只改对话。
+
+---
+
+## 1. 一句话定义
+
+一个像 Codex 桌面端的办事 Agent：用户对着聊天框说一句"我要办某件事"，助手识别业务、追问缺的资料、以对应角色登录学校的网页系统、自主找入口填表、在提交前逐项列出请用户确认，办完后记录结果，并把过程中学到的经验沉淀下来让下一次更快。
+
+## 2. 目标用户与角色
+
+| 角色 | 用什么 | 做什么 |
+|---|---|---|
+| 学校里的办事人（学生、辅导员、管理员） | 桌面端 | 说需求、补资料、在关键节点确认。**不参与知识审核** |
+| 我们团队 | 后台管理（待做） | 写出厂 YAML、审核各校沉淀的经验、看运行监控、维护密码本、交付 |
+
+## 3. 产品原则
+
+1. 只在业务允许的域名内活动。
+2. 登录凭据来自密码本或用户手动，模型永远看不到明文（browser-use `sensitive_data`）。
+3. 任何正式提交前必须用户确认；用户取消就不提交。
+4. 不猜学校没有明说的规则，宁可停下来问。
+5. 全程可审计：每步截图、progress.md、run_logs。
+6. 经验先成草稿再生效，用户端无感，审核由我们或规则完成。
+
+## 4. 架构
+
+### 4.1 现状（2026-09-17）
+
+```
+Electron 桌面端（renderer 聊天 + 右侧状态/截图/时间线）
+   │ IPC
+Python FastAPI 后端（Electron 拉起并独占，端口 8788）
+   ├─ nlu.py            意图识别 + 字段抽取（DeepSeek / 千问，一次调用，JSON）
+   ├─ orchestrator.py   状态机、按业务路由、prompt 组装、暂停/续跑、沉淀触发
+   ├─ browser/runner.py browser-use Agent，独立 Chrome，会话保活，每步截图
+   ├─ learning.py       任务成功后生成 learned 草稿
+   └─ db/database.py    psycopg 3，所有学校数据带 school_id
+PostgreSQL 17（Docker，127.0.0.1:15433）
+   knowledge / tasks / run_logs / system_accounts / learned_entries / skills / settings
+```
+
+桌面端直连 PostgreSQL，一台机器一所学校（`.env` 的 `SCHOOL_ID`）。
+
+### 4.2 目标形态
+
+```
+桌面端（编排 + 浏览器，必须在本机）  ──HTTPS──▶  服务端 API  ◀──  后台管理（我们团队，跨学校）
+                                                    │
+                                              中心 MySQL（按 school_id 隔离）+ 向量库（手册）
+```
+
+- 桌面端只保留必须在本机跑的部分：编排、browser-use、Chrome。知识、learned、账号、任务记录都走服务端接口。
+- 后台管理和桌面端用同一套接口。
+- 学校可以一校一库，也可以共库按 `school_id` 隔离，数据模型两种都支持。
+
+## 5. 知识的三层
+
+| 层 | 内容 | 存在哪 | 谁维护 | 状态 |
+|---|---|---|---|---|
+| 出厂配置 | 系统入口、登录方式、业务定义（角色、必填项、步骤、规则） | 编写格式是 `knowledge/*.yaml`，启动时灌入 `knowledge` 表，运行时读表 | 我们，来源是学校手册 + 调研；将来后台直接改表，文件只做导入导出 | 已有 |
+| 经验 learned | 入口路径、控件技巧、前置阻断、踩过的坑 | `learned_entries` 表，draft → verified / rejected，带 school_id、类别、观察次数、来源任务；YAML 里的 `learned` 只是出厂基线 | 任务成功后自动生成草稿，按内容判重归并；控件技巧 / 入口路径类被 ≥2 个任务观察到自动生效，系统规则类由我们后台人审，用户不参与 | 已有；后台审核队列待做 |
+| 参考资料 | 学校手册、通知、FAQ | 向量库（可复用已有 Qdrant），按学校 / 系统打标 | 我们导入 | 待做 |
+
+**YAML 文件与数据库的关系**：文件是给人读写的格式，表是运行时副本。现阶段文件是源头；后台做出来之后反过来，表是源头，文件用于交付。
+
+有后台之后（2026-09-17 确认）：业务定义在后台维护（表单编辑 / YAML 文本编辑 / 上传导入 / 手册生成草稿），带学校、版本、发布状态；桌面端启动时从服务端拉本校已发布的定义并本地缓存，不再随安装包带文件；仓库里只保留模板（自家学工系统出厂模板、常见第三方系统骨架），给新学校开户时从模板复制进库再改；导出仍产出 YAML，用于备份、迁移和把 A 校审核过的 learned 打包给 B 校。过渡期加一个"知识来源 = 文件 / 服务端"的配置，服务端模式下启动不再用文件覆盖库，只在该校一条业务都没有时用模板初始化一次。
+
+**有手册**：模型读手册生成 YAML 业务草稿（结构化，价值最高）；手册切块进向量库，给 Agent 一个 `lookup_manual` 工具按需查"字段是什么意思、有什么前提"。
+**没手册**：上线前按角色做一次建图扫描（枚举菜单、页面、表单字段），生成业务草稿；使用中靠 learned 沉淀；交付前预热多跑几遍，把慢的阶段藏起来。
+
+## 6. 执行模型
+
+```
+用户一句话
+ → nlu 识别业务、抽字段（今天/明天换算成日期）
+ → 缺必填项：对话追问（模型生成追问语），用户下一句再抽取合并
+ → 角色准入：业务 role 与用户在该系统密码本账号的 role 不一致 → 直接告知办不了
+ → 浏览器 profile 按 人 × 系统 × 角色；任务涉及各系统的凭据按域名分组进 sensitive_data（占位符带系统后缀），没有账号的系统按 YAML fallback（测试环境快捷登录 / 请用户手动）
+ → 业务的全部启用步骤按顺序在同一个浏览器会话里执行，前一步产物注入下一步
+ → 执行业务的启用步骤：prompt = 业务 + 目标 + 资料 + 登录方式 + 规则 + learned（YAML 基线 + 库里 verified）+ 步骤要求
+ → Agent 需要用户时调 ask_user：以 is_done 结束本轮，浏览器保活，状态 paused；用户回答后 add_new_task 续跑同一 Agent
+ → 遇到系统提示「必须先办另一件事」时调 report_blocker：按 YAML 声明的 resolution 处理。self = 问用户要不要顺带办，同意则同一会话切去办前置业务再回来；other_role / manual = 说明要找谁怎么办，用户说已处理就重试，说取消就进 blocked（可稍后继续）
+ → 提交类步骤：填完 ask_user 逐项确认 → 确认后提交，保存 submitted_record / result_message → 状态 submitted
+                                       → 取消则保存 cancelled → 状态 completed（不算提交）
+ → 成功后 learning.draft_learned 生成草稿
+ → submitted 任务按 next_check_at 由调度循环拉起只读回查步骤：approval_status 归类 → completed / rejected / 继续排期
+```
+
+判定规则：`success_artifacts_any` 覆盖 Agent 自评；`submitted_artifacts_any` 决定是否算提交；`cancelled` 优先。
+
+## 7. 已定决策（按时间）
+
+| 日期 | 决策 | 原因 / 备注 |
+|---|---|---|
+| 09-16 | 产品形态像 Codex 桌面端；一定是桌面端 | 浏览器和登录态在本机，隐私好 |
+| 09-16 | 账号由我们按角色从库里取，自动登录 | 用户不该反复输密码；用 sensitive_data 防泄露 |
+| 09-16 | 知识由我们维护交付学校；手册是来源 | 学校只管用 |
+| 09-16 | 模型 Key 先放 .env，不做用户级 Key | 阿里 / DeepSeek Key 由我们持有 |
+| 09-16 | 学工系统是自家产品，先拿它练 | 快捷登录等便利只在自家系统有，注意别依赖 |
+| 09-16 | skill / learned 全校受益；数据层用 MySQL（Docker） | 为中心化做准备 |
+| 09-16 | 提交后跟踪要做，但排在链路走通之后 | 提交不等于办完 |
+| 09-17 | 演示业务从留校申请换成辅导员查课日志填报 | 测试环境学生端没有留校申请模块 |
+| 09-17 | 学校之间数据隔离（school_id） | 不是每所学校都用我们的系统 |
+| 09-17 | 用户端不出现采纳 / 忽略；审核靠自动晋升 + 我们后台 | 办事人不该做知识审核 |
+| 09-17 | 后台管理和服务端层要做，但桌面端先夯实 | 顺序：真实提交 → 第二业务 → 后台 |
+| 09-17 | learned 判重按内容不按 key；自动晋升只对控件技巧 / 入口路径类，系统规则类必须人审 | 模型每次起的 key 不同；记错规则代价大 |
+| 09-17 | 有后台后 YAML 只做模板和导入导出，表是源头，桌面端从服务端拉配置 | 见第 5 节 |
+| 09-17 | 前置阻断做成标准机制：同角色能办的顺带办（同一会话切换目标再回来），别的角色 / 线下的说明处理方式后 blocked 等待 | 请假被返校核验拦住是真实样例 |
+| 09-17 | 桌面端登录走学校统一身份认证；业务系统登录配方要支持「统一认证跳转」，允许域名含认证中心域名 | 用户 09-17 确认 |
+| 09-17 | 密码本只服务未接统一认证的系统：学校配发账号由后台导入，个人账号才需要用户绑定。开发期手动维护密码本是权宜之计。「绑定账号界面」从演示版拿掉，换成登录配方支持 sso（登录态在 profile 里复用，缺时请用户完成一次） | 用户 09-17 指出 |
+| 09-17 | 前置阻断需要别的角色处理时，是另一个人在自己的端上用自己的账号办（如辅导员办「核实学生返校」），不是同一用户切角色；两端联动（协办请求 / 完成通知 / 自动续跑）走服务端，现阶段学生手动点「继续」 | 纠正此前「跨角色闭环」的说法 |
+| 09-17 | 目标系统自身的问题（如测试数据、缺功能）不纠结、不绕过：如实报告并 blocked，等系统方处理。我们会面对各种系统，链路跑通优先 | 学生请假被后端规则拦住是首例 |
+| 09-17 | 跨人联动（通知辅导员、协办请求、自动续跑）本阶段不做，归服务端层 | 用户 09-17 决定 |
+| 09-17 | 对照同事 PenguinUniOS 后的四项决定：桌面端按其形态重做并连打包链一起对齐；数据库切 PostgreSQL 17；继续独立仓库；执行路线保持 browser-use run() + learned | 用户 09-17 拍板，见 REFERENCE_PENGUINUNIOS.md |
+| 09-17 | 身份模型：一个人在一个系统里只有一个身份，跨系统身份可不同。密码本按「人 × 系统」存账号并记录该账号在该系统的角色；业务的 role 是准入条件而不是登录依据；跨系统任务用 browser-use 按域名分组的 sensitive_data，一个会话依次登录各系统 | 用户 09-17 指出；这是跨系统操作的前提 |
+| 10-28 | 学校工程整体移入 `browser_use/school-assistant/`，与独立获客项目 `browser_use/assistant/` 并列；各自保留独立 Git 仓库，外层只作工作区导航 | 用户要求分开两个项目，避免代码、配置和文档混在工作区根目录 |
+
+## 8. 待做设计（按建议顺序）
+
+1. ~~真实提交验证~~（09-17 完成：两条查课日志真实提交成功，状态 submitted，日期校验无问题）。
+2. ~~第二个业务~~（09-17 完成：每周谈心谈话）。~~前置阻断机制~~（09-17 完成：report_blocker + self / other_role 两条路径 + blocked 状态）。学生请假在测试环境被「返校核验」拦住；09-17 以辅导员和系统管理员探索后确认界面上没有任何角色能解开（后端业务规则作用于历史未返校记录），需学工团队清测试数据或补功能。业务 `counselor_return_verify` 已建，等系统侧有入口再补填报步骤；学生请假填报步骤同样等待。
+3. ~~防重复提交~~（09-17 完成：两个填报步骤提交前先查已有记录，重复时 ask_user）。
+4. ~~learned 自动晋升~~（09-17 完成：按内容判重，≥2 任务观察且为控件技巧 / 入口路径类自动生效，系统规则类人审；OPERATOR_MODE 控制草稿面板）。失败驱动的自动降级待做。
+5. **浏览器展开 / 收起**：~~CDP 停靠 + 最小化 / 恢复~~（09-17 完成，暂停确认时自动展开）；下一步验证 Electron WebContentsView + cdp_url 真正内嵌。
+6. **密码本升级（跨系统地基）**：~~本地部分 09-17 完成~~（role 列、角色准入、按系统分 profile、域名分组凭据）。目标形态是"用户登录桌面端 → 服务端按人返回他有账号的系统及角色、据此过滤可办业务、密码本条目清单（无密码）→ 任务开始时按需取该任务涉及系统的凭据，用完即丢并记审计"。密码本来源两条：学校配发账号由后台批量导入；个人账号由用户在桌面端「绑定账号」一次写入。当前阶段先做本地能做的部分：`system_accounts` 加 `role` 列；业务执行前做角色准入检查（当前用户在该系统的账号角色 ≠ 业务 role 就直接告知办不了）；浏览器 profile 按「人 × 系统」而非「人 × 角色」；多系统凭据按域名分组装进 `sensitive_data`，占位符带系统后缀（`x_username_lib` / `x_password_lib`），登录说明按系统分段；每系统登录配方（表单 / 统一认证 / 扫码）；生产环境放中心库并经服务端按任务取用、审计日志。
+7. ~~多步串行执行器~~（09-17 完成：步骤顺序执行、每步可声明系统、产物跨步传递、同一会话 keep_session、允许域名取并集；跨系统登录待第二个系统接入后实测）。
+8. ~~提交后跟踪~~（09-17 完成：YAML tracking、调度循环、track-now / track-stop、状态 rejected、桌面端提示；真实任务实测两次回查）。后续：回查时静默运行。
+9. **手册导入 / 建图扫描**：手册 → YAML 草稿；手册 → 向量库 + lookup_manual 工具；无手册时按角色扫描菜单和表单生成草稿。
+10. **后台管理 + 服务端层**（审核队列部分 09-17 完成，见 PROGRESS D17）：已做——`server/`（FastAPI，独立库 school_assistant_hub）+ `console/`（React 审核台），各校桌面端带凭证上报草稿、中心按内容跨校合并、智能预审（规则层 + 模型层）、人工采纳 / 驳回 / 改写、按「仅来源学校 / 所有学校」发布、桌面端按版本号增量拉回并落成本地 verified / rejected；`backend/hub_sync.py` 全后台异步，没配 HUB_URL 就是单机模式。智能采纳（09-17，PROGRESS D18）：类别硬门槛只放行控件技巧 / 入口路径，证据够硬或模型背书两条路，模型建议改写则留人，自动驳回可复活，先干跑再执行。待做——运行监控（成功率 / 步数 / 时长趋势、失败截图）、知识与密码本管理、按学校分组推送、后台多人账号；桌面端统一身份认证登录、按人过滤业务、按需取凭据；**跨人协办**：一个人的任务被别的角色的前置事项拦住时，向对应角色发协办请求，对方办完后通知并自动续跑。
+11. ~~UI 往 Codex 形态靠~~（09-17 完成：三栏布局、任务列表与回放、确认 / 阻断 / 结果卡片、我来接管）。后续：嵌入式浏览器面板。
+12. **登录配方支持统一认证**：`login.mode: sso | form | quick_login | manual`；允许域名含认证中心；有登录态直接过，没有则请用户完成一次登录后复用 profile 登录态。测试环境无 SSO，先做配置与提示词，接真实学校再验。绑定账号界面推迟到真遇到非 SSO 的个人账号系统。
+13. ~~测试集~~（09-17 完成，见 PROGRESS D16）：`npm test` 288 个用例 3.4 秒，覆盖 nlu 退路、状态判定、learned 规则与数据库生命周期、角色准入、凭据分组、阻断问句、执行结果判定、Key 兜底。`@pytest.mark.db` 的用例用一次性 `pytest_xxx` 学校隔离，PostgreSQL 不可达时自动跳过。写测试时挖出并修掉两个缺陷：关键词退路要求整段短语原样出现（模型不可用时真实说法全部误判为通用探索）、单字肯定词在句中任意位置命中（补充资料被当成同意先办前置事项）。
+14. **桌面端对齐同事的 PenguinUniOS 形态（09-17 完成，见 PROGRESS D13 / D14）**（见 `docs/REFERENCE_PENGUINUNIOS.md`）：已做——React/TS/Vite 渲染层、TS 主进程、`WebContentsView` 内嵌浏览器（browser-use 经 CDP 连 Electron 自带 Chromium，界面页走 `app://ui` 协议、主机名 ui 进白名单，不展示的视图停到窗口边缘外留 2px 在窗内而不能隐藏，否则截图挂死）、任务卡 / 确认卡 / 状态词汇对齐、Lucide 与其视觉规范、uv + PyInstaller + electron-builder 打包链（`npm run package:win` → `release/win-unpacked`，后端冻结成 exe 放 resources/backend，userData 放 .env / data / profiles）。待做——NSIS 安装器 / 图标 / 签名、Pydantic 契约生成 TS。已决：数据库已切 PostgreSQL（09-17 完成迁移）；仓库独立；打包态只支持内嵌浏览器，不带 Chromium。

+# 智能办事助手（School Assistant）
+
+跨系统智能办事助手 MVP：Electron 聊天 + Python 编排 + Browser Use 自主操作网页。
+
+本项目位于 `browser_use/school-assistant/`，与同级的 AI 获客助手 `assistant/` 分开维护；以下命令均在本项目根目录执行。
+
+产品形态类似 Codex 桌面端：左侧任务列表与历史（点开可回放过程），中间对话、任务卡与确认卡片，右侧是内嵌的浏览器面板——Agent 就在这个面板里操作学校系统，可以展开 / 收起，需要用户决定时停下来问，回答后在同一页面里继续，随时可以「我来接管」。
+
+## 当前能力（D13，2026-09-17）
+
+- 一句话发起任务：先识别业务并抽取字段（DeepSeek / 千问一次调用），缺资料时对话追问，再按业务角色登录执行
+- Agent 自主登录、找入口、填表、提交前逐项确认（演示业务：辅导员每月查课日志填报；通用探索兜底）
+- `ask_user` 暂停机制：不受 browser-use 步骤超时限制，浏览器会话保活，用户回答后续跑同一个 Agent
+- 系统账号：`system_accounts` 表按学生 + 系统存加密密码，运行时通过 `sensitive_data` 自动填写，LLM 看不到明文
+- 可观测：每步截图 `data/tasks/{id}/steps/`、进度 `progress.md`、精简执行历史存 `run_logs`
+- 自动沉淀：任务成功后提炼经验草稿（带类别），按内容判重归并；控件技巧 / 入口路径类被多个任务观察到自动生效，系统规则类由团队在运维模式下采纳。用户端无感。YAML 只是出厂基线，`GET /learned/export` 可导出交付
+- 运维模式：`.env` `OPERATOR_MODE=true` 才显示「沉淀草稿」面板，交付学校默认关闭
+- 内嵌浏览器：每个任务一个 `WebContentsView` 挂在应用右侧面板里（独立登录态分区、域名白名单），browser-use 经 Electron 的 CDP 端口直接操作它；Agent 开始操作或停下来问你时自动展开，可随时收起；运行中可「我来接管」（Agent 模式下键盘输入会被拦住并提示先接管），操作完交还给 Agent 继续。单独跑后端（无 Electron）时退回独立 Chrome 停靠模式
+- 提交后跟踪：已提交的任务定时回查审批状态，通过 / 驳回时在对话里提示，可「立即回查」或「停止回查」
+- 前置阻断：系统提示「先办另一件事」时，同角色能办的问你要不要顺带办完再回来，需要别人处理的告诉你找谁，任务进入「被前置事项拦住」等你处理好再继续
+- 多校隔离：所有学校数据带 `school_id`，实例用 `.env` 的 `SCHOOL_ID` 指定所属学校
+- 评测脚本 `scripts/eval_run.py`：同一任务连跑 N 次统计成功率 / 步数 / 时长，默认干跑（到确认即取消）。查课日志填报实测到确认 18 步 / 158 秒
+- Electron 是后端的唯一所有者：启动时自动关掉端口上残留的旧后端，退出时关掉自己的
+
+## 环境要求
+
+- **Node.js** 20.19+（Vite 8 / Electron 33 构建链）
+- **Python** 3.11+
+- **Docker Desktop**（运行 PostgreSQL 17）
+- **DeepSeek 或千问 API Key**（默认 DeepSeek）
+
+## 快速开始
+
+### 0. 启动 PostgreSQL（Docker）
+
+```powershell
+cd D:\qiekj\browser_use\school-assistant
+docker compose up -d
+```
+
+数据落在 `127.0.0.1:15433` 的 PostgreSQL 库 `school_assistant`，账号见 `docker-compose.yml`；后端启动时自动建表并同步 `knowledge/*.yaml`。2026-09-17 从 MySQL 切换而来，旧数据用 `scripts/migrate_mysql_to_pg.py` 迁移。`.env` 的 `SCHOOL_ID` 决定本实例属于哪所学校，学校之间数据互不可见。
+
+### 1. 安装 Python 依赖
+
+推荐用 uv（自动建 Python 3.12 的 `.venv`，按 `backend/requirements.lock` 精确同步，含打包用的 PyInstaller）：
+
+```powershell
+cd D:\qiekj\browser_use\school-assistant
+npm install
+npm run backend:setup
+```
+
+没有 uv 也行：脚本会用系统 Python 的 pip 把 uv 装进项目的 `native/build/` 里，不碰系统环境。手工方式：`python -m venv .venv && .\.venv\Scripts\pip install -r backend\requirements.txt`。不需要 `playwright install`，浏览器就是 Electron 自带的 Chromium。
+
+### 2. 配置 API Key
+
+复制 `.env.example` 为 `.env`，填入：
+
+```env
+LLM_PROVIDER=deepseek
+DEEPSEEK_API_KEY=sk-你的key
+LLM_MODEL=deepseek-chat
+LLM_BASE_URL=https://api.deepseek.com/v1
+```
+
+> 也可切换 `LLM_PROVIDER=qwen` 并使用 `qwen-vl-max`。
+> 可选再配一把兜底 Key `DEEPSEEK_API_KEY_FALLBACK`（千问为 `DASHSCOPE_API_KEY_FALLBACK`）：主 Key 返回 402 余额不足时，识别、沉淀和 Agent 执行中的下一次调用都自动切到兜底 Key，任务不中断；之后每 `LLM_PRIMARY_RETRY_HOURS`（默认 1）小时重试主 Key，充值后自动恢复。侧栏状态会显示「兜底 Key」。
+
+### 3. 安装并启动 Electron
+
+```powershell
+npm install
+npm start
+```
+
+`npm start` 先构建（esbuild 打主进程 / preload，Vite 打 React 渲染层，产物在 `dist/`），再启动 Electron；Electron 自己拉起 Python 后端（用 `.venv`），并在启动前关闭端口上残留的旧后端。发送任务后右侧**浏览器面板**自动展开，Agent 在里面操作；停下来提问时，点卡片按钮或直接在聊天框回答即可。只做类型检查用 `npm run check`。
+
+### 4. 录入系统账号（可选）
+
+密码本按「人 × 系统」存账号并记录该账号的角色；业务要求的角色和账号角色不一致时直接告知办不了。有账号时 Agent 自动登录（多系统时凭据按域名分组，模型看不到明文），没有则按 `knowledge/*.yaml` 里 `login.fallback_mode` 处理（测试环境用快捷登录按钮）。密码用 `.env` 的 `ACCOUNT_ENC_KEY` 加密存储：
+
+```powershell
+Invoke-RestMethod -Method Post -Uri http://127.0.0.1:8788/api/accounts -ContentType "application/json; charset=utf-8" -Body (@{ student_id = "default"; system_id = "xgxt"; role = "辅导员"; username = "工号"; password = "密码" } | ConvertTo-Json)
+```
+
+### 5. 跑测试
+
+```powershell
+npm test
+```
+
+288 个用例约 3.4 秒。其中 15 个要连本机 PostgreSQL（用一次性的测试学校隔离，跑完自动清理，不会碰到正式数据），数据库没起时自动跳过；`npm run test:fast` 直接跳过它们。覆盖意图识别与退路、状态判定、经验沉淀的判重与自动晋升、角色准入、凭据按域名分组、前置阻断问句、执行结果判定、模型 Key 兜底。
+
+### 6. 评测成功率
+
+```powershell
+npm run eval -- --n 3 --supplement "课程是高等数学，授课教师是张老师"
+```
+
+默认干跑：走到「提交前确认」自动回复取消，不会真提交；加 `--submit` 才会确认提交。`--supplement` 是任务追问时自动补充的话。结果写入 `data/eval/*.jsonl`。
+
+## 后台审核台（中心服务端）
+
+桌面端办完事会自动沉淀经验草稿。草稿要不要生效，控件技巧和入口路径类被两个任务观察到就自动生效，系统规则类必须人审。人审就在这个后台做。
+
+```powershell
+npm run hub:build   # 构建界面
+npm run hub         # 启动，打开 http://127.0.0.1:8801/
+```
+
+在「学校」页给每所学校生成一串上报凭证（只显示一次），写进那台机器的 `.env`：
+
+```env
+HUB_URL=http://中心地址:8801
+HUB_TOKEN=生成的凭证
+```
+
+之后那台桌面端会在每次沉淀后自动上报，并定时（默认 15 分钟）拉回审核结果。没配这两项就是单机模式，本地照常沉淀和自动晋升。
+
+审核台上每条草稿显示它被几所学校观察到过、累计观察多少次，可以采纳、驳回、改写后采纳，也可以批量处理。**跨校观察是最强的可信信号**：同一条知识被多所学校各自撞见，说明它不是某校特例。采纳时选发布范围：只回来源学校，还是推给所有学校。点「预审」会先让模型给建议和理由，建议只是建议，不会自动改状态。
+
+驳回也会推回各校：本地可能已经自动晋升过一条错知识，中心驳回后桌面端会停止注入它。
+
+### 智能采纳
+
+队列一次几十条时，「智能采纳」页可以把能自动定的先处理掉。**只有控件技巧和入口路径可能被自动采纳，系统规则和其他类永远留给人**，因为一条错的规则会让 Agent 以后一直绕开正确操作。
+
+自动采纳有两条路：跨校观察够或单校观察够（证据硬）；或者证据薄但模型读过内容后明确说可复用（这种只发回来源学校）。模型如果建议改写，就不会自动采纳原文，留给人确认，理由里直接给出改写建议。
+
+先点「先看会动哪些」干跑，列出每条的处置和理由，确认后再执行。自动处理过的条目标记来源为 auto，队列里勾「只看自动处理的」可复查，审错了点「退回待审」就会推回各校。
+
+**自动驳回只是暂缓**：那条知识再被观察到会退回队列重新排队。只有人工驳回是终局。这样机器误判一次不会永久吃掉一条知识。
+
+实测 43 条队列，配了模型 Key 的情况下自动处理掉 21 条（19 采纳、2 驳回，两条驳回都是带任务编号的一次性链接），剩 22 条全是按策略必须人审的。
+
+## 打包（Windows）
+
+```powershell
+npm run package:win
+```
+
+依次执行：构建桌面端（esbuild + Vite → `dist/`）→ 用 `.venv` 的 PyInstaller 把后端冻结成 onedir（`native/release/school-assistant-backend/`，约 100 MB，脚本会跑一遍 `--selfcheck` 并在本机 PostgreSQL 可达时真起一次服务验收）→ electron-builder 产出 `release/win-unpacked/SchoolAssistant.exe`（整目录约 400 MB）。冻结后端放在 `resources/backend`，知识 YAML 放在 `resources/knowledge`。
+
+运行安装包形态时，可写目录是 `%APPDATA%\school-assistant\`：首次启动会把 `.env` 模板复制过去，部署方在里面填模型 Key、PostgreSQL 连接、`SCHOOL_ID`、`ACCOUNT_ENC_KEY`；任务进度和登录态分别在其下的 `data/`、`profiles/`。目前只出免安装目录（`dir`），NSIS 安装器、图标、签名待做。

+
+## 演示业务与探索发现
+
+**当前演示业务**：辅导员工作日志填报（查课）和每周谈心谈话记录，同一入口下两个业务，由意图识别路由。谈心谈话示例：「帮我记一条谈心谈话，今天和计科2301班的李思涵聊了学业压力，内容是……」。说一句「帮我填今天的查课日志，班级计科2301班，听课记录还好」，助手会追问课程名称和授课教师，然后以辅导员身份进入「辅导员工作日志 → 日志填报 → 每月查课要求 → 新建填报」填表，逐项列出后等你确认再点「提交填报」。业务定义和探索沉淀都在 `knowledge/xuegong_demo.yaml` 的 `businesses` 与 `learned` 段。
+
+### 学生端探索发现（2026-09-16）
+
+测试环境学生端**没有「留校申请」模块**。门户 8 个一级模块：学生管理、综合测评、评奖评优、违纪处分、资助管理、请销假、节假日离返校、辅导员评议。最接近的是「节假日离返校 → 我的报备」（默认在校，离校才需报备）。学生端可提交的申请表单是「请销假 → 发起请假」，建议作为填表里程碑的目标。这些已沉淀在 `knowledge/xuegong_demo.yaml` 的 `learned` 段，运行时注入为「已知信息」。
+
+## 测试学工系统

+当前名单按行统一显示需求待核实，证据详情也使用固定待核提示。用户已经收到结果，却容易理解为还要逐条人工审核，才能完成任务。
+
+现有知识支持操作草稿、页面证据、试用回执与草稿的基础升降级。召回主要按小红书业务范围筛选，将已验证项排在草稿前，取少量条目注入，两种状态均可参与试用；相符回执会核对证据是否存在于页面，但尚未充分检查动作后的实际变化。连续排名、细粒度场景匹配、已验证经验遇到反证后的自动停用仍需完善。
+
+最近杭州跟妆任务保存了正文、评论、回复三类任务草稿，共享库实际只有一条未验证草稿，跨任务验证为零。误合并与旧快照覆盖的程序缺陷已经修复，历史记录保留。这些记录只能支持操作草稿，不能作为完整获客链路已经学会的依据。
+
+本版目标：交付状态准确，结果缺项具体，知识自动验证，复用依据可追溯，可信度随独立证据变化。操作可靠性、名单质量与业务效果分别评价。
+
+## 2 任务交付与结果信息分别表达
+
+### 任务是否完成
+
+任务完成依据用户明确要求的范围、人数和产物，由程序判断。名单已经保存并可在对话和历史中查看，就可以构成交付；用户明确要求文件时，还需成功生成对应文件。点击下载和人工审完每条线索都不作为通用完成条件。
+
+| 实际情况 | 主标题示例 | 必须保留的信息 |
+| --- | --- | --- |
+| 已达到人数或有限范围，并完成要求的产物 | 名单已交付 共20位 | 本次标准、按人去重后的数量、证据与文件入口 |
+| 目标20位，实际8位后受阻或用户停止 | 阶段成果已交付 共8位 目标20位 | 剩余12位未完成、实际停止原因、已有成果及继续选项 |
+| 执行仍在进行，但已形成部分名单 | 已整理8位 正在继续 | 真实新增成果和当前阶段，避免提前显示整任务完成 |
+| 用户要求检查的有限页面已处理，未发现符合条件的人 | 本次检查已完成 未发现符合条件的候选 | 实际读取范围与筛选依据 |
+| 页面无法读取或没有取得有效来源 | 本阶段未取得可判断的资料 | 未读范围与阻碍，不能据此称没有需求 |
+| 只要求导出已有名单且文件已生成 | 文件已生成 | 文件版本、生成时间和对应结果范围 |
+
+执行状态、目标达成程度和产物是否可查看分别记录。即使任务中断，已有文件仍可交付；生成文件也不能把尚未完成的目标改成完成。保留程序停止原因、采集原始结论及实际检索覆盖，不用新的标题掩盖原失败。
+
+### 缺失信息是否影响达标
+
+必要条件由本次目标决定。用户只要求寻找候选时，可选账号字段缺失不阻止交付；用户明确要求20个可见小红书号时，实际取得且正确归属的账号号数才计入该项完成量。用户明确规定的地区或需求条件缺少依据时，列为补充来源，不混入满足条件的数量。
+
+同一人多条原话合并。无法区分身份的来源单列，不凑人数；昵称、内部用户标识、主页入口与页面可见小红书号继续分别处理。目标未提供的产品、地区或联系方式不增加为必填项。
+
+## 3 名单与对话界面
+
+移除统一的需求待核实标签，按已有证据展示具体状态。状态必须由来源和分析字段生成，不能仅替换成更积极的固定文案。
+
+| 信息维度 | 展示方式示例 | 依据与限制 |
+| --- | --- | --- |
+| 需求表达 | 本人明确表达需求 相关需求信号 语境不足 | 回指本人原话与理由，分享经验和同行广告分别判断 |
+| 身份关联 | 来源身份可区分 主页号已获取 无法区分身份 | 保持笔记、评论、回复与主页的归属一致 |
+| 地区 | 需求原话支持 相关信息不足 地区不匹配 | 说明依据来自哪里；IP属地不作服务地点 |
+| 账号字段 | 已取得小红书号 账号号未获取 | 有主页入口不等于已取得可见账号号 |
+| 跟进进展 | 未执行 已关注 已发送 发送失败 结果未知 已回复 | 来自真实动作记录或明确反馈，已发送不等于已回复 |
+
+这些维度分别展示。例如账号已取得，但需求语境不足，不能用一个已核实标签替代全部信息。
+
+结果卡优先展示交付数量、匹配依据、具体缺项和产物。证据原话、主页入口、观察时间、未读范围按需展开。缺项分组可以筛选，用户可直接查看、导出或提出下一步要求，无需进入审核流程。
+
+保留可选的纠正这条、补充账号信息和重新按新标准分析。用户调整标准后，旧结果与文件保留原版本，系统说明哪些判断需要重算，避免将旧名单自动当作新目标成果。
+
+假设示例：用户要求整理20位候选，实际已达到目标，可以显示名单已交付共20位；下方说明其中12位有本人明确需求原话、8位为相关需求信号，以及哪些账号字段尚未取得。若用户原要求只接受明确需求，则后8位单列补充来源，本次达标人数应为12位。
+
+## 4 分层沉淀内容
+
+| 层次 | 保存内容 | 复用单位 |
+| --- | --- | --- |
+| 操作能力 | 适用页面、参数、前置条件、操作方法、成功标准、失败恢复、版本与证据 | 展开一组回复 保存某类来源 读取主页号 |
+| 阶段链路 | 操作能力组合、顺序、分支、阶段产物、恢复点及依赖版本 | 阅读讨论并归属发言人 核对账号并整理名单 |
+| 业务策略 | 适用行业与目标、搜索方向、筛选标准、反馈样本和效果来源 | 相近业务中选择搜索方向或筛选方法 |
+| 本次任务资料 | 用户目标、参数、名单、原话、授权、文件、进度和反馈 | 同一任务继续与追溯 |
+
+操作与阶段链路中的城市、关键词、对象和话术作为参数传入，不固定成上次任务内容。私密业务偏好按所属工作区和用户范围保存。个人昵称、账号、评论原话及签名链接留在任务资料，不写入通用操作方法。
+
+预置阶段模板、模型提出的方法和真实任务归纳的方法分别标记来源。预置模板可用于规划，其存在本身不增加真实验证次数。完整链路只对实际执行过的分支形成验证记录；各小操作成功不能直接推导整条链路成功。
+
+## 5 知识记录与版本
+
+每条方法记录稳定标识、能力与来源类型、适用条件、参数、步骤、预期结果、恢复方法、依赖版本，以及证据引用、独立验证数量、最近结果和当前可用状态。
+
+任务内的详细证据与共享知识元信息保持关联，避免只把一段方法文字写入共享库，却丢失它的适用条件和验证依据。能力、来源类型与版本继续按独立身份保存，不因文案相似误合并。
+
+验证记录保存方法版本、任务及目标版本、实际对象引用、运行与动作标识、动作前后证据、结果类别、原因、验证方式和时间。原始页面资料仍保留在任务证据中，共享记录只保存必要引用和去标识后的覆盖指标。
+
+知识内容改变时产生新版本，旧版本及回执可追溯。旧错配记录保留审计，默认不进入优先推荐，不通过迁移直接补成高可信知识。
+
+## 6 自动沉淀与验证
+
+执行留证 → 独立复盘整理方法 → 后续任务受控试用 → 系统核验实际变化 → 更新排序或暂停相应版本。
+
+复盘从真实动作和来源提炼方法。模型可提出候选步骤，程序为可验证的动作补齐前置条件与成功标准；只有文字描述、缺少执行依据的方法进入探索候选，不能登记为已成功验证。
+
+### 优先使用程序验收
+
+| 能力 | 自动成功依据 | 不构成成功的情况 |
+| --- | --- | --- |
+| 展开回复 | 出现新增回复或讨论标识，归属当前父评论，保存时作者和层级独立 | 仅点击过按钮 页面没有新增 有回复但归属无法判断 |
+| 保存来源 | 原话属于当前独立容器，来源类型与作者归属通过核对，记录实际持久化 | 把父评论原话保存成回复者需求 只有模型总结 |
+| 核对主页号 | 来源作者入口与实际主页匹配，页面可见账号号已读取并保存 | 只有昵称 内部profile标识 猜造链接 |
+| 名单导出 | 当前结果版本的文件存在，按人分组和必要字段符合要求，入口可打开 | 只返回文件名 路径失效 文件对应旧目标却标最新 |
+| 受授权的跟进 | 动作账本与相应页面结果一致 | 只有点击或输入记录 超时后结果未知 |
+
+先利用已产生的页面观察、来源记录和动作账本验证，不默认每一步再调用一个模型。语义有歧义时可以按需分析；仍不能判定的结果保持未知，不增加成功次数。用户纠错可以触发针对已有证据的重算，不默认重跑浏览器。
+
+任务整体未完成时，已经有独立成功依据的小操作仍可留作经验；整任务失败也不能把所有小操作都记为失败。
+
+### 统一验证结果
+
+| 结果类别 | 对知识评价的影响 |
+| --- | --- |
+| 有证据的成功 | 满足独立性条件后增加成功验证 |
+| 与方法直接相关的不符 | 增加反证，并暂停相应场景的方法版本 |
+| 平台限制 登录要求 服务不可用 | 记录阻断和适用条件，不直接算方法错误或成功 |
+| 程序执行异常 | 单独记录程序问题；未证实方法失效时不记方法反证，也不算成功 |
+| 未使用 | 保留召回记录，不计入可靠性分母 |
+| 结果未知或证据不足 | 记录缺口，不算成功或反证 |
+
+证据出现在页面中只证明它被观察到，成功还须满足方法声明的动作结果。回执由执行模型提出时，保存其来源；通过程序验收的事实与尚待系统判定的模型报告分开。
+
+## 7 独立验证与可信度排名
+
+### 先匹配适用条件
+
+先检查平台、阶段、能力、来源类型、页面结构特征、方法与依赖版本，以及本次动作是否在用户授权范围内，再比较可信度。不兼容或有未解决反证的方法暂停在当前场景使用；高分不能跳过这些条件。
+
+适用性比较使用必要的结构特征，不依赖固定屏幕坐标、临时页面索引或签名链接。每次复用仍从当前页面确认真实入口。页面变化触发重验或新版本，不永久沿用过去的成功结论。
+
+### 按独立证据累计
+
+同一方法在同一任务内重试、重复回填、导出或重启恢复，不重复增加可信度。S和F只计入选定的独立验证样本：在同一方法版本和场景统计范围内，同一任务、同一对象均最多贡献一个计数。同对象跨任务重复成功不再增加S，同一问题反复失败不重复增加F；同一任务的其他对象可增加覆盖记录。样本选择规则和参与计数的事件留档，避免只挑成功事件。
+
+重复对象出现新的相反证据时，更新其有效结论并重算相关统计；明确反证仍立即暂停对应场景，不能因统计去重忽略它。新的页面环境或方法版本使用自己的统计范围，旧证据只作历史参考。
+
+保存不可变验证事件与修订依据，按有效事件计算当前统计。重复写入保持幂等，修正旧回执时重新计算相关计数；不能数据库回执只留一行，计数却因反复提交不断增加。恢复冲突保留双方依据。按事件记录已处理位置，避免任务整体已回填标记吞掉后续新增经验回执。
+
+### 首版排序规则
+
+首版采用可解释的层级与排序，不向用户展示未经校准的成功概率。以下为用户已批准的初始规则，配置和计算规则均记录版本：
+
+1. 无独立成功验证的方法列为探索候选；有真实成功依据但样本有限的方法列为可试用。
+2. 优先复用层至少有3个独立任务、3个不同对象的有效覆盖，当前场景匹配，且没有未解决的相关反证。数量门槛只是初步保护，不单独决定排名。
+3. 在适用方法之间，结合有证据的成功与相关失败进行样本修正。可先使用排序指标 R＝（S＋1）÷（S＋F＋2），其中S、F是按独立性规则认可的成功与相关失败次数。它是内部排序指标，不是实际成功概率；少量样本仍保留样本有限标识。
+4. 同层参考证据完整度、最近有效验证、对象覆盖和当前目标相关性；可靠性相近时优先更少重复、更低模型用量的方法。不为追求低成本忽略必要证据。
+5. 已经进入优先复用的方法也持续接收反证。出现明确不适用证据时，立即暂停对应场景，记录原因；修复后用新版本或新的适用范围重新验证。
+
+方法A一次成功得到的修正指标为2/3；方法B在100个独立有效验证中成功90次，指标为91/102。排序同时展示样本与适用范围，这个比较不代表A或B的未来成功概率已经被测准。
+
+新方法通过真实用户任务中的适合环节受控试用。优先在只读、可恢复的小操作上验证，不为提高知识分数另起无关任务、额外触达用户或无限探索；已经有稳定方法时，探索不会成为交付的前置阻碍。
+
+### 知识界面
+
+知识卡显示优先复用、可试用、探索候选或当前场景暂停，并列出为什么适用、独立任务与对象覆盖、成功/反证/未知、最近验证及证据入口。保留用户可选的纠正或不适用反馈，常规路径不要求人工批准每条知识。
+
+历史数据缺少完整计量时标记历史记录不完整，不能从缺失推算为零次失败或高可靠。人工确认、程序验收和模型建议分别标明来源。
+
+## 8 阶段链路与业务效果
+
+将已具备依据的小操作组合成带参数、分支、产物和恢复点的阶段链路。规划时选择适用方法，运行中按实际页面调整；保存实际执行了哪条分支、用了哪些能力版本及哪些结果验证通过。
+
+链路技术可靠性只统计其明确终点是否完成，部分交付与受阻分别记账。修改能力或阶段版本后，旧链路记录保留，不能把旧版本成功全部归到新版本。
+
+业务效果另记三个维度：名单与目标的匹配质量、用户认可、实际跟进结果。关键词和路线只在相近行业、目标和观察范围内比较，显示有效样本与来源，负面反馈和无回复也保留。回复、确认需求和合作分别记录；不能把所有后续成交都归功于一次搜索或某条操作经验。
+
+任务👍/👎关联当时的目标和结果版本，可用于满意度及问题定位；单条纠正关联具体来源。它们不自动增加每条方法的技术成功次数。缺少逐条归因依据时，业务效果保持未知。
+
+## 9 成本与恢复
+
+沿用已有输入版本缓存、增量分析和真实供应商用量记录。知识验证优先消费现有执行证据，模型只处理需要语义判断的内容；同一事件或同一份资料重复打开不新增分析调用。
+
+持续保存任务目标、已处理对象、实际覆盖、文件版本、动作账本、方法版本及验证事件。程序重启和用户继续沿原任务接续，不因更换推荐方法清空累计进度。对未知发送结果继续保留禁止自动重发的处理，不把方法换版本当成新发送授权。
+
+保留用户明确的候选人数或有限范围，以及无默认阅读篇数、评论数、总步数和自建余额的约定。知识试用数量属于内部选择，不转化为用户的业务阅读配额。Search/Fetch继续按既有记录后续讨论，本版不扩展。
+
+## 10 实施顺序
+
+| 阶段 | 主要交付 | 进入下一阶段的条件 |
+| --- | --- | --- |
+| 第一阶段 结果表达 | 任务交付与缺项分离 目标与必要字段一致 名单按证据生成状态 | 已完成与部分交付准确，UI和CSV统计一致 |
+| 第二阶段 验证依据 | 结构化知识与证据引用 程序验收 验证事件及去重 | 重复或未知不增成功，阻断与反证区分，历史不被改写 |
+| 第三阶段 经验选择 | 场景匹配 可信度排序 受控试用 暂停与新版本 | 小样本不冒充稳定，高分不跨条件使用，旧高等级经验可失效 |
+| 第四阶段 链路与效果 | 参数化阶段组合 分支验收 用户反馈与业务效果分开归因 | 不同对象能复用，实际路径有依据，完整链路成功不靠拼接推断 |
+
+优先完成第一阶段，再建立第二阶段的事实基础，之后启用排名。第三阶段不会先给缺少验收依据的数据打高分。每阶段先运行本地回归与隔离界面验证，再借用户已授权任务中的适合环节进行真实验证；没有合适任务时保留尚未真实验证，不另起平台任务。真实关注、私信沿用明确对象及话术授权。
+
+当前技术栈和桌面视觉继续沿用，功能调整集中在拓客编排、来源投影、学习回执、知识存储及结果卡。迁移可重复执行，保留历史来源、文件、草稿、旧版本、授权和动作记录；不为了新界面统一改写旧任务成已完成。
+
+## 11 验收清单
+
+| 验收场景 | 预期结果 |
+| --- | --- |
+| 已达20位，只有可选字段缺失 | 显示名单已交付20位，逐项说明缺失，不要求逐条审核 |
+| 目标20位，8位后中断且已生成文件 | 文件可用，显示阶段成果8/20及真实原因，不改成整任务完成 |
+| 目标明确要求20个可见小红书号 | 未取得号的对象不计入该项完成量，昵称与内部ID不代填 |
+| 已读有限范围后没有符合条件的人 | 交付真实检查结论；未读取或无来源不能伪装成零需求 |
+| 身份未知或同人多条发言 | 未知单列，同人合并，人数和证据条数分开 |
+| 用户改目标后打开旧名单或文件 | 标明旧版本；原资料保留，不计新目标达成 |
+| 页面有证据文字，但展开操作无新增 | 不算展开成功，保存实际观察和结果 |
+| 同任务重复回填、导出、恢复或修订回执 | 不重复增加试用和成功数，计数与有效事件一致 |
+| 同对象跨任务反复成功或重复失败 | 不重复抬高S或F；有新的反证时更新结论并暂停相关场景 |
+| 平台限制、超时或未采用方法 | 分别记阻断、未知或未用上，不当方法反证 |
+| 程序异常导致动作未完成 | 记录程序故障，方法正确性保持未知，不直接扣方法可靠性 |
+| 已优先复用的方法出现明确不适用 | 暂停对应场景并留原因，历史成功记录保留 |
+| 高排名方法与当前来源类型或页面版本不匹配 | 不直接复用，选择适用方法或重新观察 |
+| 新方法仅一次成功，旧方法多对象稳定验证 | 展示样本差异，不能仅按原始成功率判新方法最佳 |
+| 用户给整份结果点赞 | 保存结果版本评价，不将所有客户或所有操作升级 |
+| 同一来源与标准再次分析 | 复用已有判断，未强制重做时不新增模型分析调用 |
+| 任务整体失败但部分操作证据成立 | 分别记录已成功的小操作与未完成阶段，不整体洗白或全部否定 |
+| 高可信方法包含当前未获授权的触达 | 不执行，知识排名不能扩大用户动作范围 |
+| 旧错配草稿或缺失历史验证数据 | 保留原记录，标明历史或冲突，不自动补成功次数 |
+
+每阶段报告实际变化、本地测试、真实模型和真实平台验证范围，以及尚未解决的问题。最终验收需确认用户能直接使用交付结果，系统能依据独立证据选择和停用方法，且完整链路与获客效果均可追溯。
+
+## 12 用户已确认的实施依据
+
+用户已要求执行以下建议；其中真实验证须由后续已有授权任务产生，不能用迁移或测试补造：
+
+1. 结果以已完成或阶段成果已交付呈现，缺项按字段说明，取消统一的人工待复核感受。
+2. 知识由系统自动沉淀、试用和验证，人工纠错为可选补充，不设置日常逐条审核关卡。
+3. 复用先看适用条件，再按独立证据、样本修正可靠性、近期表现及成本排序；分数用于选择方法，不代表成交或未来成功概率。
+4. 初始采用探索候选、可试用、优先复用和当前场景暂停；优先复用的3任务、3对象门槛及修正排序指标作为首版起点，后续按真实数据调整并保留规则版本。
+5. 按结果表达、自动验收、经验排名、链路与效果四阶段实施，保留现有任务数据与授权范围。
+
+## 13 首轮实现范围与验证边界
+
+- **交付**：程序分别计算运行状态、必要条件达成和产物交付。名单、CSV及达标停止共享按人分组与必要字段口径；明确要求的小红书号、本人需求、地区或CSV才纳入必要条件。没有取得有效来源与检查后零匹配分别展示。旧标准结果保留，不能算当前达标。
+- **证据与方法**：新增工作区隔离的结构化方法、不可变验证事件和业务反馈三张表。保存来源、展开回复、核对主页、生成文件均接程序验收器；任务内保留前后快照，共享知识只存引用与去标识对象。短时无新增、加载或归属未知不能算成功，也不自动算方法反证。模型建议和模型回执不能自行增加技术成功数。
+- **选择与追溯**：适用条件先行，独立任务/对象匹配去重、相关反证暂停、依赖版本与分支终点验收、幂等重放及修订重算已接通。规则版本为 `independent-evidence-v1`。知识卡显示状态、样本、原因及原任务前后快照；用户反馈为可选，不设置逐条人工审批。
+- **已接的阶段链路**：限于同篇正文与一条独立评论或回复均成功保存，依赖两条真实操作回执，并保留实际执行分支。它不证明已读完评论，不证明搜索→详情→展开全部回复→主页→触达全链路完成。其余阶段组合与业务策略效果仍需积累后扩展。
+- **页面版本限制**：`xhs_visible_dom_v1` 当前代表DOM适配器版本，并非自动识别出的全部平台页面变体；每次工具调用仍核对当前入口和归属。动态页面变体分类及其跨变体复用继续待真实样本验收。
+- **历史与业务效果**：历史错配草稿不修写、不补成功，缺失统计标为未记录，默认不参与自动召回。👍/👎、方法纠错及回复/合作等用户后续反馈单独记账，不能增加技术成功或直接证明获客归因。真实工作区当前仍只有原未验证历史草稿，尚无可宣称的跨任务优先复用或最优获客策略。
+- **本地验收**：后端全量、类型构建、程序取证/入库/召回/导出贯通与CUA隔离界面验证已覆盖；测试工作区与本机UI夹具不计真实经验。本轮未调用真实模型、Search/Fetch或小红书，不执行关注私信。实际测试数量、截图及桌面加载情况记录在 [PROGRESS D36](PROGRESS.md)。
