+# 深度研究第三轮：检索稳定性修复 + 参考文献确定性 + 页面对齐 AI 写作改造
+
+## A. 两个 bug 的排查结论与修复
+
+### A1. 第二次检索「网络波动」——确认是真问题（DDG 限流 + 错误语义混淆 + 零重试）
+
+**排查结论**（用户判断"确实是网络波动"基本正确，但代码层面放大了它）：
+- 「网络波动」文案不存在于任何代码中——是收集员 LLM 看到 `{"error": "No results found"}` 信封后自己编的解释
+- 真实根因：DDG html 端点对同 IP 快速连续请求限流（403/429 挑战页）→ `DDGSException` → `ddg_search/tools.py::_search_text` 把异常吞成 `[]` → 上层把「被限流」和「真没结果」混成同一个错误信封；工具层完全没有重试
+
+**修复**（`packages/harness/deerflow/community/ddg_search/tools.py`）：
+1. `_search_text` 对异常加 2 次重试 + 指数退避（约 1.5s / 3s + 抖动）
+2. 错误信封区分场景：真无结果 → `no results`；多次尝试仍失败 → `web search failed after N attempts (rate limited or network), 换一组检索词稍后重试`——让模型不再瞎猜「网络波动」
+3. 收集员 SOUL.md 行为准则加一条（同步改种子资产 + 已安装副本 `.deer-flow/agents/deep-research-collector/`）：搜索返回 error 信封时先换检索词重试一轮，而不是直接告知用户网络异常
+
+### A2. 参考文献缺失——代码确有隐患（当前是模型自发行为，时有时无）
+
+**排查结论**：后端没有任何「参考来源」追加逻辑；四个 runner 的报告 prompt 只要求内联 `[N]` 引用。出现过的参考列表是模型看到上下文头 `[N] 标题（URL）` 后**自发**补写的——弱模型下不可靠，与"信息够不够"无必然关系。
+
+**修复**（prompt 指示 + 确定性兜底双保险）：
+1. 四个 runner（basic / detailed / deep / multi_agent）的报告 prompt 各加一条：报告最后附「## 参考来源」，按 `[N] 标题. URL` 列出正文实际引用过的来源
+2. `basic.py` 新增共享函数 `ensure_reference_section(report, context_list, materials)`：报告缺少参考小节时，解析正文引用的 `[N]` 编号，按压缩上下文顺序生成编号列表追加（无编号时列全部来源，封顶 20 条；已有参考小节则不重复追加）。在各 runner 最终 `write_text("report.md", ...)` 前调用（约 7 个调用点，跳过零材料 fallback）
+3. 新增测试 `tests/test_deep_research_references.py`：helper 单测（正常追加/编号映射/不重复追加/无 URL 来源）+ runner 集成断言
+
+## B. 页面改造（核心需求）：左列复用 AI 写作对话形态，右列改真沙箱
+
+### B1. 左列 = AI 写作式对话收集面板（仿 WritingSetupChat）
+
+- **空状态欢迎屏**（无消息时隐藏头部，展示欢迎卡片，WritingWelcome 式）+ 有消息后 `MessageList`（沿用现有绑 collector 线程的接线）+ 首 token 前「正在整理…」占位条
+- **输入框换成白卡片 PromptInput 套件**（与 AI 写作完全同款组件）：卡片内一行「当前对话模型」Select（沿用 ModelNameSelect）+ 高级配置入口；下方 PromptInputTextarea + PromptInputFooter + PromptInputSubmit（`status` ready/streaming，流式中变停止按钮）。经典模式入口保留在高级配置对话框
+- **配置卡片进对话流**（对标 AI 写作「识别出意图后出现表单」）：
+  - `message-list.tsx` 最小扩展（约 15 行）：新增分组 `assistant:research-approval`（识别 `additional_kwargs.setup_research_approval`）+ 可选 prop `researchApprovalSlot?: ReactNode`；不传 slot 或无该载荷时零行为变化——普通对话/AI 写作完全不受影响
+  - workbench：收集回合结束（awaiting_report，即"意图识别完成"）时向 `displayThread` 尾部注入一条虚拟 ai 消息（WritingSetupChat 的 displayThread 同款手法），slot 传现有 `ReportConfigCard` → 卡片作为助手下一轮出现在对话流里
+- 写作进度卡、完成卡、摘要气泡、追问列表保留在列表下方卡片区（报告正文移到右侧沙箱）
+
+### B2. 右列 = 工作区真沙箱（Step2SandboxLayout 的 stub 线程模式）
+
+- 新建 `deep-research/ResearchSandboxPanel.tsx`（约 100 行，含关闭/重开）+ `useReportSandbox.ts` hook（仿 `useStep3Report` 的 stub 机制）：
+  - threadStub：`messages = [{type:'ai', tool_calls:[{name:'write_file', args:{path:'/mnt/user-data/outputs/report.md', content: <流式报告>}}]}]`，`isLoading = job 运行中 && phase !== 'summarizing'`
+  - `report_delta` 首帧 → `openArtifact(write-file: 虚拟URL)` 自动展开右栏；`run.report` 每帧 upsert stub（带防抹空守卫）；刷新/切换会话用 `session.reportMarkdown` 重建
+  - `ArtifactFileDetail` 自带能力全部免费获得：**流式期 code 视图自动滚底 → 报告写完 isLoading 翻 false 自动切 preview + 脉冲提示**（正是「生成完直接切预览」）、Streamdown 渲染的 Markdown（比现在的好看）、另存 Word/复制/下载、默认走展示层脱敏
+- 布局：ResizablePanelGroup chat 60 / sandbox 40（对齐 ChatBox/圆桌），沙箱可关闭、头部按钮重开
+- **删除自定义 `ResearchSandbox` 组件**；legacy 会话与经典模式共用同一右栏（`run.report` 数据源相同，行为一致）
+- 已知小限制（可接受）：报告配图模式下沙箱内图片可能无法经 artifacts API 解析（配图默认关闭；真需要时后续把产物落 thread artifacts）
+
+### B3. 验证
+
+- 后端：`PYTHONPATH=. uv run --no-sync pytest tests/ -k deep_research -q --ignore=tests/test_notification_templates.py` 全绿 + ruff；改完配置/SOUL 后 touch 触发 dev 服务重载
+- 前端：`pnpm typecheck` 零新增错误（基线 51）
+- 手动走查：连续两次检索不再误报、弱模型报告末尾必带参考来源、页面全流程（欢迎屏 → 对话收集 → 流内配置卡 → 沙箱流式 → 自动预览 → 摘要/追问）
+
+## 涉及文件
+
+**后端**：`community/ddg_search/tools.py`、`deep_research/runners/{basic,detailed,deep,multi_agent}.py`、收集员 SOUL.md（种子 + 已安装副本）、`tests/test_deep_research_references.py`（新）
+**前端**：`components/workspace/messages/message-list.tsx`（可选 slot 分组）、`pages/deep-research/DeepResearchWorkbench.tsx`（大改）、`pages/deep-research/ResearchSandboxPanel.tsx`（新）、`pages/deep-research/useReportSandbox.ts`（新）
+
+## 明确不动
+
+- AI 写作 / 普通对话现有组件行为（message-list.tsx 仅加可选分组，缺省零变化）
+- 报告写作管线的写作逻辑本身（prompt 加一条要求 + 末尾确定性追加参考小节，均为附加式）
+- 深度研究后端会话/任务/事件模型（本轮不动）

 ### Full Application (from repo root)
@@ -81,15 +88,19 @@ The frontend (`frontend-web/`) is a React 19 + Vite SPA:
 - **Pages**: `ChatPage` (thread chat), `AgentChatPage` (custom agent chat), `AgentsPage`/`NewAgentPage` (agent management), `ScheduledTasksPage`/`ScheduledTaskRunDetailPage` (scheduled tasks), `LightAppManagementPage`/`LightAppListPage`/`LightAppIframeView` (轻应用中心 — register/list/embed mini-apps)
 - **AI 写作·对话版（对话驱动写作台）**: a **parallel new entry** beside the classic AI-writing page (classic page/routes untouched) — route `/page/canvas/ai-writing-chat`, sidebar 「问答管理 → 课题研究(对话版)」. Page `open-canvas/pages/AIWritingChatPage.tsx` reuses the engine (`AIWritingContext` + `useStream` + `AIWritingDraftPanel`); **idle keeps the classic setup layout** (`WritingSetupChat` + collapsible form) and switches to the chat workbench once writing starts; left panel `components/ai-writing-chat/WritingChatPanel.tsx` = **unified chronological feed** (`ChatFlowTimeline.tsx`, chat bubbles anchor-interleaved into the progress timeline so triggered events render below the user's message) + button-only intervention cards (`ChatInterventionCards.tsx`, inline textareas removed) + bottom unified smart composer. Intent resolution: frontend fast path + `POST /api/ai-writing/sessions/{id}/intent` → `deerflow/agents/ai_writing/intent_router.py` (per-pause action whitelist, high-cost confidence gates, payload cleaning); supports QA bypass, clarify follow-ups, control intents, and material-stage auto re-search + pending-intent resume. Tests `tests/test_ai_writing_intent.py`; plan doc `frontend-web/docs/ai-writing-对话驱动写作台-实现方案.md`.
 - **轻应用中心 (Light App Center)**: a sibling of 任务管理 in the sidebar with two pages — 应用管理 (admin registers `window_open` or `iframe` mini-apps with a route-param builder: login params resolved from `localStorage.userInfo`, theme params literal) and 应用列表 (card grid of `window_open` apps, `window.open` launch). `iframe` apps are mounted under a chosen parent menu (XK/PG/TY/综合管理) and **dynamically injected into the sidebar** by `core/page-layout/use-sidebar-menu.ts` (`useSidebarMenuItems`), opening in the `LightAppIframeView` host. Client + React Query hooks in `strategy-components/api/light-apps.ts`; URL builder/constants in `strategy-components/lib/light-app.ts`. Backend: `/api/light-apps` (global/shared, admin-gated writes).
-- **菜单管理 (Menu Management, admin-only)**: an **overlay** over the static sidebar menu — `MenuManagementPage` (`pages/MenuManagementPage.tsx`, route `/page/strategy/admin/menu-management`, opened from the admin-only 「菜单管理」 item in the **bottom-left settings dropdown** of `components/page-sidebar.tsx`). Admins rename / 停用·启用 / reorder (↑↓ or @dnd-kit drag) / re-parent (horizontal drag **or** the edit dialog's 「移动到」parent selector) any node across 一级/二级/三级, **including injected iframe light-app nodes** (`light-app-<appId>`). The static tree (`core/page-layout/sidebar-menu.ts`) stays the source of icons/routes; only per-node deltas (`label`/`disabled`/`parentId`/`sortOrder`) persist to the backend. Merge logic in `core/page-layout/menu-overrides.ts` (`applyMenuOverrides`, applied in `use-sidebar-menu.ts` after light-app injection, before role filter; disabling a node hides its whole subtree) — strict **3-level cap** (`wouldExceedDepth`). Client `strategy-components/api/menu-overrides.ts`. Backend: `/api/menu-overrides` (global/shared; open read, admin atomic replace-all).
+- **菜单管理 (Menu Management, admin-only)**: an **overlay** over the static sidebar menu — `MenuManagementPage` (`pages/MenuManagementPage.tsx`, route `/page/strategy/admin/menu-management`, opened from the admin-only 「菜单管理」 item in the **bottom-left settings dropdown** of `components/page-sidebar.tsx`). Admins rename / 停用·启用 / reorder (↑↓ or @dnd-kit drag) / re-parent (horizontal drag **or** the edit dialog's 「移动到」parent selector) any node across 一级/二级/三级, **including injected iframe light-app nodes** (`light-app-<appId>`).

Client `strategy-components/api/menu-overrides.ts`. Backend: `/api/menu-overrides` (global/shared; open read, admin atomic replace-all). **简介模式** uses a separate overlay: every compact workspace menu item can be placed in `sidebar`（左侧菜单）、`settings`（设置和更多）or `toolbox`（右侧工具箱）; `CompactToolbox` (`components/workspace/compact-toolbox.tsx`, mounted by `PageRoutes.tsx`) opens only when the square right-edge trigger is clicked, then slides a compact, content-height right-side drawer over a backdrop above global dropdowns; configured items render top-to-bottom as centered square cards with a large icon above the label while the effective layout is compact. `/api/compact-menu-overrides` stores two independent sets (type `A` / `B`); each website picks one via `runtime-config.js` `VITE_COMPACT_MENU_TYPE`.
+- **舆情分析智能体（前端虚拟智能体）**: 智能体管理页新增「舆情分析」类型 tab，固定一张虚拟智能体卡片（名称/简介可编辑，存 localStorage）。对话页 `pages/SentimentAgentChatPage.tsx`（路由 `agents/sentiment-analysis/chats/:thread_id`）复用普通问答布局 + `MessageList`，**输入框只有发送按钮**；问答经 Gateway `POST /api/sentiment-agent/stream` 转发外部 AG-UI 网关（不经过 LangGraph），会话仅存 sessionStorage。接口地址 + Basic Auth 在 `runtime-config.js` 配置（`VITE_SENTIMENT_AGENT_API_URL` / `_AUTH_USERNAME` / `_AUTH_PASSWORD`）并随请求传给后台；后台按传入地址转发、关闭 TLS 校验，失败时把完整错误回传。核心模块 `src/core/sentiment-agent/`。
+- **简洁模式用户引导 (Compact-mode onboarding tour)**: 简洁模式（外观设置的「全量/简洁」= compact，无全局导航栏 + 页面侧边栏）新增 TDesign React `Guide` 组件驱动的分步引导。组件 `components/workspace/compact-mode-guide.tsx`（挂在 `ChatPage`）：9 步 —— 欢迎弹窗（dialog 模式）→ 左侧功能导航 → 聊天记录 → 设置和更多 → 换肤 → 界面模式（切回全量）→ 常用提示词栏 → 提示词管理弹窗 → 输入框；高亮目标由各组件上的 `data-compact-guide` 标记定位（`workspace-nav-chat-list` / `recent-chat-list` / `workspace-nav-menu` / `appearance-controls` / `custom-prompt-menu.tsx` 的 `CustomPromptBar`（提示词栏，仅新对话落地态渲染）与其 `ManagePromptsDialog`（`prompt-dialog` 锚点）/ ChatPage 输入框容器），**启动时按目标是否存在过滤步骤**（如新用户无聊天记录、侧栏收起时自动剔除该步 —— Guide 对缺失元素会抛错，不能盲传）。**提示词管理弹窗步骤是动态目标**：弹窗平时不渲染，引导切到该步前先广播 `PROMPT_DIALOG_GUIDE_EVENT`（`custom-prompt-menu.tsx` 导出）让 `CustomPromptBar` 打开 `ManagePromptsDialog` 并**接管**（`owner: true` 期间 ESC/点遮罩不关闭，防止高亮目标消失导致 Guide 报错），轮询锚点真正挂载后才切步；离开该步 / 跳过 / 完成 / 中途卸载时以 `owner: false` 收回弹窗，4 秒打不开则跳过该步防卡死。**TDesign Guide × Radix 模态互操作**：Radix 模态弹窗打开时会把 `body` 置 `pointer-events:none`（滚动锁定），Guide 直接挂在 body 下的遮罩/高亮/弹层会一并继承失活（引导按钮点不动），`styles/tdesign-theme.css` 末尾对 `.t-guide__overlay/__highlight/__popup/__wrapper` 显式 `pointer-events:auto` 兜底。触发：① 自动 —— 简洁模式新对话落地页自动演示，直到用户显式点「完成」或「跳过」才写 localStorage `deerflow.compact-guide-finished` 记忆（浏览器级）；**中途刷新/离开不记忆，下次进入还会再演示**。② 手动 —— 「设置和更多」下拉新增「界面使用引导」（该下拉仅存在于简洁模式工作区侧栏 footer）：已在问答页时广播 `compact-guide:start` 窗口事件直接启动，否则写 sessionStorage 请求并导航 `/chats/new` 由挂载的引导消费（消费在定时器真正启动时才执行，规避 StrictMode effect 双跑吞请求）。`eligible` 排除 embed=1 / hideChrome=1 / chats_iframe / FORCE_COLLAPSED_SIDEBAR（无界）等同样无全局 chrome 的特殊环境；启动延迟 800ms 等侧栏宽度过渡稳定后再测量高亮框。
+- **智能体使用引导 (Agent onboarding tour, 三段式)**: 智能体「浏览管理 → 创建与配置 → 发起问答」全流程分步引导，组件 `components/workspace/agents/agent-guide.tsx`（同一 TDesign `Guide` 封装模式，与简洁模式引导共享记忆语义：**仅显式点「完成/跳过」才写 localStorage** `deerflow.agent-guide.<stage>.finished`，中途刷新/离开不记忆）。**自动演示仅 create / chat 两段**（进智能体列表页不弹引导，点「创建智能体」进入新建页时才自动演示；list 段的 `AgentGuide` 传 `autoStart={false}`，只能由头部「使用引导」按钮手动触发）。三段各自挂载、各自记忆：① `list`（`agent-gallery.tsx`，/page/workspace/agents）——分区 Tabs、搜索排序、智能体卡片操作、右上「创建智能体」按钮；**完成/跳过就地结束（不跳转创建页，与 create 段无联动）**，最后一步仅提示进入创建页后会有配置引导；② `create`（`NewAgentPage.tsx`，/page/workspace/agents/new）——左侧对话式创建输入区、基本信息、运行模型+入库模板名、知识空间、SOUL.md、技能穿梭框、保存按钮（9 步）；③ `chat`（`AgentChatPage.tsx`，agents/:id/chats）——左栏切换与历史、常用问题 chips、输入框（落地态/会话态两个挂点同一 `chat-input` 标记）、右侧详情面板；`eligible` 限定普通智能体对话页（`showAgentList && !isEmbedded && !taskCtxOn`，即排除通用问答原地嵌入与任务深链工作区），三段共用 `isAgentGuideEnvironment()` 排除 embed/hideChrome/无界环境。高亮锚点 `data-agent-guide`：列表页 `tabs`/`search`/`agent-card`（卡片+列表两种布局的根元素）/`new-agent-btn`，创建页 `create-chat-input`/`create-basic`/`create-model`/`create-knowledge`/`create-soul`/`create-skills`/`create-save-btn`，对话页 `chat-sidebar`/`chat-questions`/`chat-input`/`chat-detail`；同样**启动时按目标存在性过滤步骤**（新用户无卡片/无预设问题时自动剔除）。手动重放：三个页面头部各有「使用引导」按钮（列表页创建按钮左侧、创建页 header 右侧、对话页 header），广播 `agent-guide:start:<stage>` 窗口事件强制重放（忽略已看过记忆）。
 - **敏感词管理 (Sensitive Word Management)**: configures the **展示层脱敏映射** (原始词 → 替换词). **Gated on the username `lqq`** (not the admin role) — `getAccountDisplayName().toLowerCase() === "lqq"` (username = email `@` prefix, else `user_id`, same as the profile page); the dropdown entry, the route guard, and the page-level guard all use this check. `src/lib/desensitize.ts` ships a frozen seed map `SEED_DESENSITIZE_MAP` (the deployment seed) plus a live mutable `DESENSITIZE_MAP` (initialized from the seed so `desensitize()` works before any fetch). `DesensitizeWordsLoader` (mounted in `App.tsx` `AppProviders`) fetches `/api/sensitive-words` on startup and, if non-empty, calls `replaceDesensitizeMap(...)` to make the backend config the source of truth (empty/failed → keep seed). Page `SensitiveWordsPage.tsx` (route `/page/strategy/admin/sensitive-words`, opened from the 「敏感词管理」 item in the **bottom-left settings dropdown** of `components/page-sidebar.tsx`, present in **both** full + collapsed sidebar modes) lists/adds/edits/启停/deletes words and saves the **whole set atomically** (replace-all); a 「导入种子词」 button merges any missing `SEED_DESENSITIZE_MAP` entries into the editor. Client + hooks in `strategy-components/api/sensitive-words.ts` (`wordsToMap` folds enabled rows into the runtime map). Backend: `/api/sensitive-words` (global/shared; open read, write allowed for admin **or** the `lqq` account), mirroring 菜单管理's store shape. **侧边栏 + 导航栏 menu labels are desensitized** at the data source: `useSidebarMenuItems`/`useActiveThirdLevel` (`core/page-layout/use-sidebar-menu.ts`) map every node's `label` through a desensitizer built **directly from the `/api/sensitive-words` query** (`makeDesensitizer(wordsToMap(words))`, falling back to the global seed `desensitize` while empty) — this sidesteps the `replaceDesensitizeMap` effect-timing race. Only `label` is rewritten; `path`/`id`/`icon` are untouched so routing/highlight are unaffected. All nav surfaces (`page-sidebar.tsx`, `page-sidebar-dark.tsx`, `page-sidebar-v1.tsx`, `strategy-components/Header.tsx`, `PageRoutes.tsx`) consume this hook and are covered; `MenuManagementPage` uses the raw tree so admins still edit real labels.
 - **技能地址管理 (Skill Address Management, admin-only)**: 扫描运行中的技能（`skills/{public,custom}` 下所有 `.md`/`.py`）里的 **http(s) URL 与 IP/IP:端口**，按唯一地址聚合全部出现位置（跨 .md/.py），支持**批量替换**（如把 UAT 地址一次性改成生产）。主体抽成可复用组件 `SkillAddressesPanel`（`pages/SkillAddressesPage.tsx` 导出，默认导出 `SkillAddressesPage` 仍保留旧路由 `/page/strategy/admin/skill-addresses` 作直链回退），**作为「技能地址管理」标签页嵌入管理员「技能管理」页 `pages/AdminSkillsPage.tsx`**（该页加 Tabs：「技能列表」+「技能地址管理」；入口在「设置和更多」下拉的「技能管理」`workspace-nav-menu.tsx` → `/page/workspace/admin/skills`，不再单列于 `components/page-sidebar.tsx` 左下角设置下拉）：打开自动扫描并带**进度条**（扫描逐技能 / 应用逐文件 X/N，应对 150+ 技能），URL/IP 类型过滤 + 搜索 + 「片段批量套用」（如所有 `uat.4.cn` → `prod.4.cn`）、每地址「替换为」输入框（可展开看 `file:line` 片段）、内联**预览**、**应用**、**多关键词检索**（空格分隔全部命中），以及**修改记录**面板——每次应用生成一条记录（显示时间/改了哪些地址 from→to/文件数/处数），可**针对单次记录回退**（二次确认）。client + NDJSON 流式解析在 `strategy-components/api/skill-addresses.ts`。后端 `/api/skill-addresses`（**仅管理员**）：所有文件 IO 走 `asyncio.to_thread` 不阻塞事件循环；`GET /scan`(+`/scan/stream`)、`POST /preview`、`POST /apply`(+`/apply/stream`)、`GET /backups`、`POST /rollback/{id}`；**子串安全替换**（基于 token span，不会误伤子串）、`expected_total` 乐观锁（409）、写前自动磁盘备份到 `{skills_root}/.address-edits/`（同时写一份 `{id}.manifest.json` 记录本次替换明细，供修改记录展示）、应用后刷新技能系统提示缓存。纯引擎 `deerflow/skills/address_scan.py`，router `app/gateway/routers/skill_addresses.py`，tests `tests/test_skill_addresses.py`。范围仅运行中技能，不动 `deploy/minimal/skills/`。
-- **按钮管理 (Task Button Management, admin-only)**: configures the **可配置跳转按钮** rendered in the left task panel of the task deep-link workspaces (rwfx / 3qfx / xdfx, see `TaskFxWorkspace`). Each button = `{business, label, linkType, target, appendTaskId, idParam, idKind, enabled, sortOrder}`; `linkType` is `url` (外链 `window.open`, optional append of `?{idParam}={id}` — **`idParam` is the editable query-param name**, e.g. `id`/`task_id`), `business` (内部切换到另一业务, reuses `resolveTaskDeeplinkTarget`, always task id), or `purpose` (弹出当前任务的「任务目的」表格 via the shared `TaskPurposeDialog`, no target — configurable for any page incl. xdfx). **`idKind` (`task`/`action`) only matters for xdfx**: its deep-link `?taskId=` is an 行动id and the 任务id is resolved at login (`fetchTaskIdFromAction`) — `TaskContext` now also stashes the raw `actionId`, so a url button can append either (default `task`). Page `TaskButtonsPage.tsx` (route `/page/strategy/admin/task-buttons`, **admin-gated**, entry「按钮管理」in the bottom-left settings dropdown of `components/page-sidebar.tsx`, both full + collapsed modes) has per-business tabs, edits name/type/target/启停/排序/增删, saves the **whole set atomically** (replace-all), plus 「导入默认」 to merge code-seed defaults. **Seed/fallback** (like 敏感词管理): only when the whole table is empty (fresh deploy, never saved) do the workspace + page fall back to `defaultTaskButtons(cfg)` — rwfx's url buttons (编辑/下一步/3q详情) built from the **live** `/api/public/config/task-deeplink` plus cross-business switch buttons for **all three** businesses (each switches to the other two — rwfx→三情/行动, 3qfx→任务/行动, xdfx→任务/三情). Once saved, the store is the sole source of truth. The old hardcoded jump buttons were migrated out: `TaskFxWorkspace` no longer hardcodes 切换到三情分析, `TaskActionsPanel` keeps only the non-jump 清除记录, and `TaskPurposePanel` dropped its 3q详情 button (now configurable) **and defaults the 目的树 table to collapsed** (chevron toggle). Helpers `core/auth/task-buttons.ts` (`TaskButton`, `defaultTaskButtons`, `resolveTaskButtons`, `buttonsForBusiness`, `runTaskButton`), client+hooks `strategy-components/api/task-buttons.ts`. Backend: `/api/task-buttons` (global/shared; open read, admin replace-all), store `deerflow.persistence.task_buttons` (table `task_buttons`, auto-created by `create_all`), wired `app.state.task_button_store`.

 - **State**: TanStack Query for server state, context providers (`SubtasksProvider`, `ArtifactsProvider`, `PromptInputProvider`) scoped to `WorkspaceRoutes`
 - **LLM streaming**: `@langchain/langgraph-sdk` streams messages from the backend via SSE
 - **UI**: Radix UI primitives + TailwindCSS v4 + shadcn-style components in `src/components/ui/`
 - **Shims**: `src/shims/` provides `next/link` and `next/navigation` polyfills (original code was Next.js)
 - **Login URL params** (`LoginPage.tsx`, frontend-only — the backend never sees these): besides the auth params (`ticket`/`userId`/`env`/`theme`/`yUserId`/`token`/`access_token`/`authToken`/`password`), the page supports a **task deep-link** via `?taskId=&goPath=`. After login it calls the consumer API `GET {VITE_AIPI_CONSUMER_URL}/taskAnalyseSearch/cop-task-detail?taskId=` (header `Authorization: Bearer admin`, auto-injected by `utils/request.ts`), stashes the full `data` (`id/overview/taskDirection/taskName/taskContent`) into `sessionStorage["login.copTaskDetail"]`, then routes by `goPath`: base codes `3qfx`/`rwfx`/`xdfx` → that business's configured **single agent** Q&A inside a **任务工作区** (resolved via `/api/business-mapping`; `resolveTaskDeeplinkTarget` calls `persistTaskContext({taskId, agentId, openingText})` and navigates to the `…/chats` **index**, which opens the latest task conversation or 新建 — a 1:N task↔对话 workspace, NOT `pendingAgentMessage`); the `-A` suffix (`3qfx-A`/…) → **multi-agent roundtable** with `roundtablePrefill.businessCode` so the page auto-selects the configured 业务链条. **xdfx's deep-link `?taskId=` is actually an 行动id, not a 任务id** — `resolveDeeplinkTaskId(goPath, rawId)` (called in `LoginPage` before everything) detects `xdfx`/`xdfx-A` and resolves it via `GET {action_detail_url}/{actionId}` → `data.taskId` (`fetchTaskIdFromAction`; `action_test`+`mock.action_detail` for offline testing); the resolved 任务id then drives `cop-task-detail`, the purpose tree, and the 1:N binding (other businesses pass the id through unchanged). **xdfx additionally partitions its chat records by 行动id (action_id), NOT by task_id**: `resolveTaskDeeplinkTarget` sets `partitionByAction:true` + keeps the raw action_id as `TaskContext.actionId`, so new threads are tagged `metadata.{taskId,actionId}` (taskId kept only to preserve the backend「任务深链对话全局共享」semantics, which keys off `metadata.taskId`) and the conversation list filters by `actionId` (+`agent_id`) — different actions of the same task get separate lists. xdfx's first-question opening text also appends `行动id（action_id）为…` (see `buildOpeningText` / `taskThreadMetadata`). goPath→businessCode: `3qfx`→`3Q`, `rwfx`→`6BF`, `xdfx`→`7BF`. The roundtable target also threads the URL `taskId` into `roundtablePrefill.taskId` (`resolveTaskDeeplinkTarget(goPath, detail, taskId)`), which turns on two taskId-scoped behaviors: (1) **separate, unpartitioned per-task storage** — taskId 会商聊天记录 live in their **own** store/table (`roundtable_task_drafts`), keyed **only by `task_id`** (one taskId = many records, shared across users, **no user 分权** at all; `created_by` is audit-only), kept entirely out of the per-user personal store (`roundtable_drafts`, now strictly per-user) so the two never mix. Backend router `/api/roundtable-task-drafts` (`GET /by-task/{id}` + `/by-task/{id}/latest`, `POST`, `GET/PUT/DELETE /{id}` — all user-agnostic); frontend client `roundtable-planning/api/task-drafts.ts`, and `useDraftPersistence`/`useRoundtableDrafts` route **all** CRUD to it when a `taskId` is present (else the personal `drafts.ts`). The matching **background jobs** are shared by task too: `roundtable_jobs.task_id` marks a task job; reads/dedup/stream/resume/cancel pass `?task_id=` so any user opening the task sees the same running 研讨 (progress/flowchart), and the executor writes the final report back to the task-draft store. Existing rows are moved over by `scripts/migrate_roundtable_task_drafts.py` (migration `20260618_01`). The history dropdown filters to the task and 新建 keeps the binding; (2) **Step-3 auto structured output** — after the `roundtable-summary` agent writes the Markdown report it automatically runs a second round emitting a `flow-json` flowchart (`useStep3Summary` `autoFlow`+`chainLevels`), whose hierarchy follows the business chain's stage goals (任务 → 目的 → 行为体 → …; coordinatorPrompt-specified hierarchy wins) and whose nodes never carry 阶段编号/阶段名 (the prior bug). **Both targets render embedded under the 任务管理 layout** — nested routes under `task-management/<business-path>/{roundtable,agent/:agent_id/chats}` in `StrategyRoutes.tsx` (`<business-path>` = `plan-task-sentiment` / `plan-task/plan-task-fx` / `plan-task/plan-task-action`, matching the COH中任务 menu paths in `sidebar-menu.ts`) so the global sidebar keeps 任务管理 → COH中任务 → the matching business highlighted. **All three single-agent businesses share `TaskFxWorkspace`** (`task-components/TaskFxWorkspace.tsx`): left = a「当前任务」card (`readCopTaskDetail()` 任务名称 + 简介, desensitized, 留存 above 新建对话) + per-task 1:N conversation list (`useTaskThreads(taskId, agentId, actionId?)` — filtered by **both** `metadata.taskId` AND `metadata.agent_id` so the three businesses' conversations staLine truncated

 ### Configuration

CLAUDE.md

@@ -82,13 +82,13 @@ The frontend (`frontend-web/`) is a React 19 + Vite SPA:
 - **定时任务「JSON → HTML 模板填充」(模板数据转换器)**: a third scheduled-task execution mode. In the create/edit dialog (`ScheduledTasksPage.tsx`), selecting the built-in agent **「模板数据转换器」** (`execution_agent_name === "template-json-builder"`, `TEMPLATE_BUILDER_AGENT_ID`) reveals a 「HTML模板」 select (`useHtmlTemplates` → `GET /api/scheduled-tasks/html-templates`) + a **.json 上传** button (reads the file's text into the prompt box) and **hides** the 必须生成 HTML/Markdown switches (this mode always outputs HTML). The chosen template persists as `execution_context.template_config.template_id` (`TemplateFillConfig` in `core/scheduled-tasks/types.ts`). At run time the backend converts the source JSON (the task prompt) into that template's `DATA` structure, validates (retry-on-fail), fills the template, and stores an HTML page previewable via the existing run-detail HTML preview. The source can be **pure JSON, plain text, or text-with-embedded-JSON** — the backend pre-extracts any embedded JSON and the agent's `SOUL.md` maps it (or the plain text's semantics) to the template's schema skeleton. **Chat-page debug entry (only this agent's `AgentChatPage`)**: when `agent_id === "template-json-builder"`, the chat header shows a 「页面模板」 select + a 「渲染预览」 button — after a normal Q&A run, the button takes the **latest AI reply**, POSTs it to `POST /api/scheduled-tasks/template-fill/render` (`renderTemplateFill`), and pops a dialog rendering the filled HTML in a `sandbox="allow-scripts"` iframe plus the structure-validation status/errors/gaps — for debugging the agent's conversion effect without creating a scheduled task. Gated strictly on the agent id, so other agents' chat pages are untouched. See the backend CLAUDE.md「Template-fill mode」for the engine (`deerflow/runtime/scheduler/template_fill.py`), agent seed, dispatch, and the render API.
 - **AI 写作·对话版（对话驱动写作台）**: a **parallel new entry** beside the classic AI-writing page (classic page/routes untouched) — route `/page/canvas/ai-writing-chat` (`OpenCanvasRoutes.tsx`), sidebar 「问答管理 → 课题研究(对话版)」. Page `open-canvas/pages/AIWritingChatPage.tsx` fully **reuses the engine** (`AIWritingContext` state machine + LangGraph `useStream`, `AIWritingHistoryProvider`, right-side `AIWritingDraftPanel`) but replaces the presentation: left = `components/ai-writing-chat/WritingChatPanel.tsx` (timeline + **button-only intervention cards** `ChatInterventionCards.tsx` — the five pause cards copied from `InterventionCard.tsx` with all inline textareas removed, confirm/action buttons kept — plus a bottom **unified smart composer**). Free text goes through two-level intent resolution (`open-canvas/api/ai-writing-intent.ts`): deterministic short-phrase fast path (确认/继续/重新搜索/重写大纲…; high-cost actions never fast-pathed) then `POST /api/ai-writing/sessions/{id}/intent` — the backend reads the graph checkpoint (authoritative pause point from the pending interrupt) and routes via `deerflow/agents/ai_writing/intent_router.py` (LLM + strict per-pause action whitelist aligned to the graph's real resume actions, confidence gates: finalize/force_finalize/覆盖式 re_search need ≥0.85 else clarify, payload key-whitelist cleaning). Results map to `submitIntervention`/control (暂停/继续/后台挂起)/QA bypass (`answer` rendered as a chat bubble, never touches graph state)/clarify (amber follow-up bubble with multi-turn context). **Two-state layout**: idle (未开始写作) renders the **classic setup experience unchanged** — `WritingSetupChat` + collapsible `AIWritingPanel` form under `WritingFormProvider` (same as `AIWritingPage`'s idle branch); once writing starts (or history view opens) it switches to the chat workbench. **Unified chronological feed** (`ChatFlowTimeline.tsx`): intent-layer chat bubbles are interleaved INTO the progress-event timeline by anchor (= `progressEvents.length` at message creation), so events triggered by a user message render **below** it (Google-AI-Studio-style single stream, not timeline-above/chat-below); composer-driven interventions suppress the duplicate 「我的要求」card (`suppressedRequirementIndices`). **素材不足自动续跑** only at `material_confirm` (the only pause the graph supports re-search from): needResearch caches the payload as a pending intent, submits `re_search + userQuery`, and auto-submits the pending intent when the new material-confirm pause arrives (cancellable pill). Stage chips + per-stage placeholder + 「当前交互对象」status badge. Backend tests `tests/test_ai_writing_intent.py`. Plan doc: `frontend-web/docs/ai-writing-对话驱动写作台-实现方案.md`.
 - **轻应用中心 (Light App Center)**: a sibling of 任务管理 in the sidebar with two pages — 应用管理 (admin registers `window_open` or `iframe` mini-apps with a route-param builder: login params resolved from `localStorage.userInfo`, theme params literal) and 应用列表 (card grid of `window_open` apps, `window.open` launch). `iframe` apps are mounted under a chosen parent menu (XK/PG/TY/综合管理) and **dynamically injected into the sidebar** by `core/page-layout/use-sidebar-menu.ts` (`useSidebarMenuItems`), opening in the `LightAppIframeView` host. Client + React Query hooks in `strategy-components/api/light-apps.ts`; URL builder/constants in `strategy-components/lib/light-app.ts`. Backend: `/api/light-apps` (global/shared, admin-gated writes).
-- **菜单管理 (Menu Management, admin-only)**: an **overlay** over the static sidebar menu — `MenuManagementPage` (`pages/MenuManagementPage.tsx`, route `/page/strategy/admin/menu-management`, opened from the admin-only 「菜单管理」 item in the **bottom-left settings dropdown** of `components/page-sidebar.tsx`). Admins rename / 停用·启用 / reorder (↑↓ or @dnd-kit drag) / re-parent (horizontal drag **or** the edit dialog's 「移动到」parent selector) any node across 一级/二级/三级, **including injected iframe light-app nodes** (`light-app-<appId>`). The static tree (`core/page-layout/sidebar-menu.ts`) stays the source of icons/routes; only per-node deltas (`label`/`disabled`/`parentId`/`sortOrder`) persist to the backend. Merge logic in `core/page-layout/menu-overrides.ts` (`applyMenuOverrides`, applied in `use-sidebar-menu.ts` after light-app injection, before role filter; disabling a node hides its whole subtree) — strict **3-level cap** (`wouldExceedDepth`). Client `strategy-components/api/menu-overrides.ts`. Backend: `/api/menu-overrides` (global/shared; open read, admin atomic replace-all).
+- **菜单管理 (Menu Management, admin-only)**: an **overlay** over the static sidebar menu — `MenuManagementPage` (`pages/MenuManagementPage.tsx`, route `/page/strategy/admin/menu-management`, opened from the admin-only 「菜单管理」 item in the **bottom-left settings dropdown** of `components/page-sidebar.tsx`). Admins rename / 停用·启用 / reorder (↑↓ or @dnd-kit drag) / re-parent (horizontal drag **or** the edit dialog's 「移动到」parent selector) any node across 一级/二级/三级, **including injected iframe light-app nodes** (`light-app-<appId>`). The static tree (`core/page-layout/sidebar-menu.ts`) stays the source of icons/routes; only per-node deltas (`label`/`disabled`/`parentId`/`sortOrder`) persist to the backend. Merge logic in `core/page-layout/menu-overrides.ts` (`applyMenuOverrides`, applied in `use-sidebar-menu.ts` after light-app injection, before role filter; disabling a node hides its whole subtree) — strict **3-level cap** (`wouldExceedDepth`). Client `strategy-components/api/menu-overrides.ts`. Backend: `/api/menu-overrides` (global/shared; open read, admin atomic replace-all). **简介模式** left-nav is a separate overlay: `/api/compact-menu-overrides` stores two independent sets (type `A` / `B`); each website picks one via `runtime-config.js` `VITE_COMPACT_MENU_TYPE`.
 - **白名单管理 (Login Whitelist, admin-only)**: gates **who may log in**, run as a **blocklist (黑名单模式)**. Two pieces: a global master switch (`system_settings.json → login_whitelist.enabled`, surfaced by **admin-only** `GET|PUT /api/system-settings/login-whitelist`) + a per-user **放行** flag (`users.approved` column, migration `20260625_02`). Users **self-register** as usual and **every new account defaults to `approved=True`** — so a user who has never logged into this system before is allowed straight through; the switch only blocks users an admin has explicitly **取消放行** (`approved=False`). (`create_user`/`User`/`UserRow` all default `approved=True`; admins are always approved; existing rows are backfilled `True`.) Login interception is the single helper `enforce_user_approved(user)` in `app/gateway/routers/auth.py`, called in all three login endpoints (`/login/{local,username,token}`) **after** the account is resolved/created and **before** the JWT is issued: switch off → everyone passes; `system_role=="admin"` → always passes (anti-lockout); else `approved=False` (admin-revoked) → 403 `{code:"PENDING_APPROVAL"}` (the frontend's `extractErrorMessage` surfaces the message and login throws before writing any auth state, so no half-login). Admin approves on `pages/LoginWhitelistPage.tsx` (route `/page/strategy/admin/login-whitelist`, entry「白名单管理」in the bottom-left settings dropdown of `components/page-sidebar.tsx`, both sidebar modes): a top master-switch + a list of all registered users (`GET /api/v1/auth/users`, now carrying `approved`) with a per-row 放行 Switch (`PUT /api/v1/auth/users/{id}/approval`, admin-only; revoking only blocks the **next** login — `token_version` is left untouched, existing sessions are not force-killed). Client/hooks: switch in `strategy-components/api/login-whitelist.ts`, user list + approval in `core/auth/{api,hooks}.ts` (`useSetUserApproval`). Backend tests: `tests/test_login_approval.py`. **账号级「登录口令」(per-account password — 临时开通)**: the same page also lets an admin assign one specific account an individual **plaintext** password (`users.login_password` column, migration `20260625_04`, nullable; auto-added on startup by `_ensure_orm_columns_sync`). Once set, **that account's** username login (`POST /api/v1/auth/login/username`) **requires** `?password=` to exactly match it and that personal password **takes precedence over** the global shared-password gate (`username_login.require_password`); accounts without one keep today's shared-gate / passwordless behavior. The user then logs in via the **existing** frontend URL `#/login/<用户名>?password=xxxx` (LoginPage already forwards `?password=`; `<用户名>` = the account's email `@`-prefix). **Plaintext is intentional** — the password rides in the URL query anyway, so storing it readably lets the admin re-copy the full login link from the page; it is exposed only on the **admin-only** `GET /api/v1/auth/users` (`UserListItem.login_password`) and the new admin-only `PUT /api/v1/auth/users/{id}/login-password` (set non-empty / clear with null·empty; doesn't touch `token_version`). The whitelist page renders a per-user 「登录口令」 column with a set/修改 editor + a live 「复制登录链接」 button (`useSetUserLoginPassword` in `core/auth/hooks.ts`, `setUserLoginPassword` in `core/auth/api.ts`). Backend gate helper `_lookup_user_by_username` (lookup-only, no auto-register) in `routers/auth.py`; tests `tests/test_login_personal_password.py`.
 - **敏感词管理 (Sensitive Word Management)**: configures the **展示层脱敏映射** (原始词 → 替换词). **Gated on the username `lqq`** (not the admin role) — `getAccountDisplayName().toLowerCase() === "lqq"` (username = email `@` prefix, else `user_id`, same as the profile page); the dropdown entry, the route guard, and the page-level guard all use this check. `src/lib/desensitize.ts` ships a frozen seed map `SEED_DESENSITIZE_MAP` (the deployment seed) plus a live mutable `DESENSITIZE_MAP` (initialized from the seed so `desensitize()` works before any fetch). `DesensitizeWordsLoader` (mounted in `App.tsx` `AppProviders`) fetches `/api/sensitive-words` on startup and, if non-empty, calls `replaceDesensitizeMap(...)` to make the backend config the source of truth (empty/failed → keep seed). Page `SensitiveWordsPage.tsx` (route `/page/strategy/admin/sensitive-words`, opened from the 「敏感词管理」 item in the **bottom-left settings dropdown** of `components/page-sidebar.tsx`, present in **both** full + collapsed sidebar modes) lists/adds/edits/启停/deletes words and saves the **whole set atomically** (replace-all); a 「导入种子词」 button merges any missing `SEED_DESENSITIZE_MAP` entries into the editor. Client + hooks in `strategy-components/api/sensitive-words.ts` (`wordsToMap` folds enabled rows into the runtime map). Backend: `/api/sensitive-words` (global/shared; open read, write allowed for admin **or** the `lqq` account), mirroring 菜单管理's store shape. **侧边栏 + 导航栏 menu labels are desensitized** at the data source: `useSidebarMenuItems`/`useActiveThirdLevel` (`core/page-layout/use-sidebar-menu.ts`) map every node's `label` through a desensitizer built **directly from the `/api/sensitive-words` query** (`makeDesensitizer(wordsToMap(words))`, falling back to the global seed `desensitize` while empty) — this sidesteps the `replaceDesensitizeMap` effect-timing race. Only `label` is rewritten; `path`/`id`/`icon` are untouched so routing/highlight are unaffected. All nav surfaces (`page-sidebar.tsx`, `page-sidebar-dark.tsx`, `page-sidebar-v1.tsx`, `strategy-components/Header.tsx`, `PageRoutes.tsx`) consume this hook and are covered; `MenuManagementPage` uses the raw tree so admins still edit real labels.
 - **技能地址管理 (Skill Address Management, admin-only)**: 扫描运行中的技能（`skills/{public,custom}` 下所有 `.md`/`.py`）里的 **http(s) URL 与 IP/IP:端口**，按唯一地址聚合全部出现位置（跨 .md/.py），支持**批量替换**（如把 UAT 地址一次性改成生产）。主体抽成可复用组件 `SkillAddressesPanel`（`pages/SkillAddressesPage.tsx` 导出，默认导出 `SkillAddressesPage` 仍保留旧路由 `/page/strategy/admin/skill-addresses` 作直链回退），**作为「技能地址管理」标签页嵌入管理员「技能管理」页 `pages/AdminSkillsPage.tsx`**（该页加 Tabs：「技能列表」+「技能地址管理」；入口在「设置和更多」下拉的「技能管理」`workspace-nav-menu.tsx` → `/page/workspace/admin/skills`，不再单列于 `components/page-sidebar.tsx` 左下角设置下拉）：打开自动扫描并带**进度条**（扫描逐技能 / 应用逐文件 X/N，应对 150+ 技能），URL/IP 类型过滤 + 搜索 + 「片段批量套用」（如所有 `uat.4.cn` → `prod.4.cn`）、每地址「替换为」输入框（可展开看 `file:line` 片段）、内联**预览**、**应用**、**多关键词检索**（空格分隔全部命中），以及**修改记录**面板——每次应用生成一条记录（显示时间/改了哪些地址 from→to/文件数/处数），可**针对单次记录回退**（二次确认）。client + NDJSON 流式解析在 `strategy-components/api/skill-addresses.ts`。后端 `/api/skill-addresses`（**仅管理员**）：所有文件 IO 走 `asyncio.to_thread` 不阻塞事件循环；`GET /scan`(+`/scan/stream`)、`POST /preview`、`POST /apply`(+`/apply/stream`)、`GET /backups`、`POST /rollback/{id}`；**子串安全替换**（基于 token span，不会误伤子串）、`expected_total` 乐观锁（409）、写前自动磁盘备份到 `{skills_root}/.address-edits/`（同时写一份 `{id}.manifest.json` 记录本次替换明细，供修改记录展示）、应用后刷新技能系统提示缓存。纯引擎 `deerflow/skills/address_scan.py`，router `app/gateway/routers/skill_addresses.py`，tests `tests/test_skill_addresses.py`。范围仅运行中技能，不动 `deploy/minimal/skills/`。
-- **按钮管理 (Task Button Management, admin-only)**: configures the **可配置跳转按钮** rendered in the left task panel of the task deep-link workspaces (rwfx / 3qfx / xdfx, see `TaskFxWorkspace`). Each button = `{business, label, linkType, target, appendTaskId, idParam, idKind, openMode, loginParams, appendAuth, authTokenParam, authNameParam, enabled, sortOrder}`; `linkType` is `url` (外链 `window.open`, optional append of `?{idParam}={id}` — **`idParam` is the editable query-param name**, e.g. `id`/`task_id`), `business` (内部切换到另一业务, reuses `resolveTaskDeeplinkTarget`, always task id), or `purpose` (弹出当前任务的「任务目的」表格 via the shared `TaskPurposeDialog`, no target — configurable for any page incl. xdfx). **`url` buttons support two independent, coexisting login-append mechanisms**: (1) **`loginParams` (追加登录参数, like 应用管理/Light App Center)** — a list of `{key, source, customValue}` resolved at click time: `runTaskButton` reads `userInfo` (via `readUserInfo` from `strategy-components/lib/light-app`, embed-isolated through `authStorage`) and appends `?{key}={value}` for each (`source` = a userInfo field such as `accessToken`/`yUserId`, or `other` → literal `customValue`); empty list = nothing appended. Reuses `LOGIN_SOURCE_OPTIONS` from light-app; stored as JSON column `task_buttons.login_params_json` (`PortableJSON`, migration `20260625_01`). (2) **`appendAuth` (追加登录态)** — appends `?{authTokenParam}={token1}&{authNameParam}={username}` (default param names `token`/`username`) so the跳转目标外部系统 can identify the current user — e.g. `…/action/sentiment?token=<JWT>&username=lizhaoxing`. **Gated on token login**: `token1` = the `?authToken=` used by token-exchange login; `username` = the raw login name the backend resolved from `getTokenInfo`. Both are stashed at login by `persistLoginCredentials` into `login.token1`/`login.username` (`core/auth/login-credentials.ts`, scoped via [[scoped-storage]] so嵌入/独立会话隔离 + 随独立会话迁移). Only token login writes them → a non-token-login session has no `token1`, so `runTaskButton` silently skips the auth append (the jump still works, just without those two params). The frontend reads `username` straight from the new `UsernameLoginResponse.username` field (the stored email local-part is lossy — lowercased/normalized — so not used), **not** by decoding the JWT. Stored as columns `task_buttons.{append_auth, auth_token_param, auth_name_param}` (migration `20260625_02`). The admin page renders both editors for `url` buttons (loginParams 虚线框 + 追加登录态 switch). **`idKind` (`task`/`action`) only matters for xdfx**: its deep-link `?taskId=` is an 行动id and the 任务id is resolved at login (`fetchTaskIdFromAction`) — `TaskContext` now also stashes the raw `actionId`, so a url button can append either (default `task`). Page `TaskButtonsPage.tsx` (route `/page/strategy/admin/task-buttons`, **admin-gated**, entry「按钮管理」in the bottom-left settings dropdown of `components/page-sidebar.tsx`, both full + collapsed modes) has per-business tabs, edits name/type/target/启停/排序/增删, saves the **whole set atomically** (replace-all), plus 「导入默认」 to merge code-seed defaults. **Seed/fallback** (like 敏感词管理): only when the whole table is empty (fresh deploy, never saved) do the workspace + page fall back to `defaultTaskButtons(cfg)` — rwfx's url buttons (编辑/上一步/下一步/3q详情) built from the **live** `/api/public/config/task-deeplink` plus cross-business switch buttons for **all three** businesses (each switches to the other two — rwfx→三情/行动, 3qfx→任务/行动, xdfx→任务/三情). Once saved, the store is the sole source of truth. **Bottom 快捷跳转 bar groups by prev/next**: `TaskJumpBar` renders only「上一步/下一步」-type buttons in the bottom bar — a `prev` group (id 含 `prev` 或文案「上一步」, 描边次要样式 + ←图标) rendered **左侧**, then a `next` group (id 含 `next` 或文案「下一步」, 实心主色) on the **右侧** (container `justify-end`); everything else goes to the right-edge floating menu. The default 上一步 button (`rwfx-prev`, `url`, target = `DASHBOARD_AGENT_ROUTE` `/page/strategy/dashboard-agent`, `appendTaskId` + `idParam=taskId` → `?taskId=任务id`, `openMode=self`) 默认指向**应用内**「大屏绘制」页，在 **both** 单智能体 (`TaskFxWorkspace`) 与 多智能体会商 (`RoundtablePlanningPage` 深链 rwfx-A) 都显示（共用 `TaskJumpBar`）。**`runTaskButton` 的 `url` 类型支持应用内路由**：target 以单个 `/` 开头时按内部路由处理——`self` 走 react-router 同窗导航（不刷新），`blank` 拼成当前源的 hash 路由新标签打开；外链行为不变。 The old hardcoded jump buttons were migrated out: `TaskFxWorkspace` no longer hardcodes 切换到三Line truncated
+- **按钮管理 (Task Button Management, admin-only)**: configures the **可配置跳转按钮** rendered in the left task panel of the task deep-link workspaces (rwfx / 3qfx / xdfx, see `TaskFxWorkspace`). Each button = `{business, label, linkType, target, appendTaskId, idParam, idKind, openMode, loginParams, appendAuth, authTokenParam, authNameParam, enabled, sortOrder}`; `linkType` is `url` (外链 `window.open`, optional append of `?{idParam}={id}` — **`idParam` is the editable query-param name**, e.g. `id`/`task_id`), `business` (内部切换到另一业务, reuses `resolveTaskDeeplinkTarget`, always task id), or `purpose` (弹出当前任务的「任务目的」表格 via the shared `TaskPurposeDialog`, no target — configurable for any page incl. xdfx). **`host`（宿主路由）** asks the embedding parent to navigate: `runTaskButton` sends `window.parent.postMessage({ type:'HOST_NAVIGATE', path, queryParams:{ [idParam]: Number(taskId) } }, hostOrigin)` — `target` is the host route (e.g. `/task/item-aiceh/step-analysis-audience`), `appendTaskId`/`idParam` become numeric `queryParams` (task id only), origin from `runtime-config.js` `VITE_HOST_NAVIGATE_ORIGIN` (else ancestorOrigins/referrer; never `*`). Independent-tab clicks toast and do nothing. **`url` buttons support two independent, coexisting login-append mechanisms**: (1) **`loginParams` (追加登录参数, like 应用管理/Light App Center)** — a list of `{key, source, customValue}` resolved at click time: `runTaskButton` reads `userInfo` (via `readUserInfo` from `strategy-components/lib/light-app`, embed-isolated through `authStorage`) and appends `?{key}={value}` for each (`source` = a userInfo field such as `accessToken`/`yUserId`, or `other` → literal `customValue`); empty list = nothing appended. Reuses `LOGIN_SOURCE_OPTIONS` from light-app; stored as JSON column `task_buttons.login_params_json` (`PortableJSON`, migration `20260625_01`). (2) **`appendAuth` (追加登录态)** — appends `?{authTokenParam}={token1}&{authNameParam}={username}` (default param names `token`/`username`) so the跳转目标外部系统 can identify the current user — e.g. `…/action/sentiment?token=<JWT>&username=lizhaoxing`. **Gated on token login**: `token1` = the `?authToken=` used by token-exchange login; `username` = the raw login name the backend resolved from `getTokenInfo`. Both are stashed at login by `persistLoginCredentials` into `login.token1`/`login.username` (`core/auth/login-credentials.ts`, scoped via [[scoped-storage]] so嵌入/独立会话隔离 + 随独立会话迁移). Only token login writes them → a non-token-login session has no `token1`, so `runTaskButton` silently skips the auth append (the jump still works, just without those two params). The frontend reads `username` straight from the new `UsernameLoginResponse.username` field (the stored email local-part is lossy — lowercased/normalized — so not used), **not** by decoding the JWT. Stored as columns `task_buttons.{append_auth, auth_token_param, auth_name_param}` (migration `20260625_02`). The admin page renders both editors for `url` buttons (loginParams 虚线框 + 追加登录态 switch). **`idKind` (`task`/`action`) only matters for xdfx**: its deep-link `?taskId=` is an 行动id and the 任务id is resolved at login (`fetchTaskIdFromAction`) — `TaskContext` now also stashes the raw `actionId`, so a url button can append either (default `task`). Page `TaskButtonsPage.tsx` (route `/page/strategy/admin/task-buttons`, **admin-gated**, entry「按钮管理」in the bottom-left settings dropdown of `components/page-sidebar.tsx`, both full + collapsed modes) has per-business tabs, edits name/type/target/启停/排序/增删, saves the **whole set atomically** (replace-all), plus 「导入默认」 to merge code-seed defaults. **Seed/fallback** (like 敏感词管理): only when the whole table is empty (fresh deploy, never saved) do the workspace + page fall back to `defaultTaskButtons(cfg)` — rwfx's url buttons (编辑/上一步/下一步/3q详情) built from the **live** `/api/public/config/task-deeplink` plus cross-business switch buttons for **all three** businesses (each switches to the other two — rwfx→三情/行动, 3qfx→任务/行动, xdfx→任务/三情). Once saved, the store is the sole source of truth. **Bottom 快捷跳转 bar groups by prev/next**: `TaskJumpBar` renders only「上一步/下一步」-type buttons in the bottom bar — a `prev` group (id 含 `prev` 或文案「上一步」, 描边次要样式 + ←图标) rendered **左侧**, then a `next` group (id 含 `next` 或文案「下一步」, 实心主色) on the **右侧** (container `justify-end`); everything else goes to the right-edge floating menu. The default 上一步 button (`rwfx-prev`, `url`, target = `DASHBOARD_AGENT_ROUTE` `/page/strategy/dashboard-agent`, `appendTaskId` + `idParam=taskId` → `?taskId=任务id`, `openMode=self`) 默认指向**应用内**「大屏绘制」Line truncated
 - **实时并发监控 (Concurrency / System-Pressure Monitor, admin-only)**: a live panel mounted at the **top of the admin 排行榜 page** (`components/workspace/admin/concurrency-monitor.tsx` `ConcurrencyMonitorPanel`, rendered in `pages/AdminUserLeaderboardPage.tsx`) showing **当前并发的大模型调用数 + 列表（用户/智能体/类型/已运行时长）**, each row with a 「停止」button (and a 「全部停止」) that **truly aborts** that run's in-flight model stream via `RunManager.cancel` (`POST /api/admin/active-runs/{run_id}/cancel`) — to relieve pressure when 使用人数过多. Two line charts (minute/hour toggle): **并发量折线图** (peak/avg, `GET /api/admin/active-runs/concurrency`, fed by a lightweight background sampler into `concurrency_samples`) and **大模型出字速度折线图** (tokens/sec, `GET /api/admin/active-runs/token-speed`, aggregated from `llm_call_metrics`) so a dip pinpoints where the bottleneck is. A **「后台采样」Switch** (`system_settings.json → concurrency_monitor.enabled`, **default off / opt-in**, `GET|PUT /api/admin/active-runs/settings`) turns the background sampling on/off **at runtime, no restart** (the live concurrency count + 「停止」 work even while sampling is off — only the 并发量 history chart needs it on); everything is designed to **never impact production** (one tiny INSERT/15s, retention-purged, best-effort). Client/hooks: `core/admin/active-runs.ts` + `core/admin/hooks.ts` (`useActiveRuns`/`useConcurrencySeries`/`useTokenSpeedSeries`/`useCancel*`/`useMonitorSettings`). See the backend CLAUDE.md「Admin Concurrency Monitor」.
-- **会话冲突 409 中文化**: when a user submits a new question while the previous turn is still streaming, the backend's `RunManager.create_or_reject` rejects with HTTP 409 (`services.py` now returns a **Chinese** detail「当前对话还在生成回答…」). `core/threads/hooks.ts` `onError` detects the conflict (`isActiveRunConflictError`: 409 / "already has an active run" / the Chinese text) and shows a friendly `toast.info` instead of a raw error.

+## 1. 文档用途与读法
+
+### 1.1 这份文档解决什么问题
+
+岗位会商右侧「文件预览沙箱」看起来像普通对话页的产物预览，但实现路径完全不同。历史上这块反复出过：
+
+- 沙箱不实时打开，要等全文写完才弹；
+- 打开了但内容冻住，生成完才一口气灌进去；
+- 整页卡顿，连消息列表文字都不实时；
+- 同轮「重新生成」第二次写入时，步骤条变了，沙箱却不动；
+- 第一次正常，关掉后再问就不实时。
+
+这些 bug **特别容易在「重做页面 / 换布局 / 自己重写开沙箱逻辑」时复现**。本文把正确对接方式、时序、接口、禁区和排障步骤写全，方便下一位同事直接按文档接线，而不是再靠猜。
+
+### 1.2 建议读法
+
+| 你的目标 | 先读哪些章节 |
+| --- | --- |
+| 从零接一个新页面壳 | 第 3、5、6、7、8、12、15、16 节 |
+| 只改对话子组件探测逻辑 | 第 7、9、12、13 节 |
+| 线上排障 | 第 13、14 节，必要时回看第 10 节 |
+| 理解为什么不能用页面 state | 第 2、10、13 节 |
+
+### 1.3 对照代码（以仓库为准）
+
+| 角色 | 路径 |
+| --- | --- |
+| 页面壳（唯一沙箱宿主） | `frontend-web/src/position-roundtable/pages/PositionRoundtablePage.tsx` |
+| 节点对话（探测 write_file、上报预览） | `frontend-web/src/position-roundtable/components/PositionNodeChat.tsx` |
+| 收口对话 | `frontend-web/src/position-roundtable/components/PositionBuiltinAgentChat.tsx` |
+| 预览 UI（共享组件，勿分叉逻辑） | `frontend-web/src/components/workspace/artifacts/artifact-file-detail.tsx` |
+| 流式正文读取 | `frontend-web/src/core/artifacts/loader.ts` → `loadArtifactContentFromToolCall` |
+| 普通对话页对照（步骤条自动开） | `frontend-web/src/components/workspace/messages/message-group.tsx` |
+| 模块总览 | `frontend-web/src/position-roundtable/README.md` |
+
+---
+
+## 2. 背景：为什么岗位会商要单独做沙箱
+
+### 2.1 普通对话页怎么开沙箱
+
+普通对话页（`ChatPage`）大致是：
+
+```text
+ArtifactsProvider（页面级）
+  └─ ChatBox / MessageList
+       └─ message-group 渲染 write_file 步骤
+            └─ 发现 path 且 autoOpen → artifacts.select + setOpen(true)
+  └─ 右侧 ArtifactFileDetail 读同一套 ThreadContext
+```
+
+要点：
+
+- 对话和预览共享同一套 `ThreadContext`（同一个 `useThreadStream`）。
+- 步骤条组件自己就能触发打开。
+- 流式 `content` 本来就在当前 React 树的 thread 里，不需要「把 thread 镜像到别的地方」。
+
+### 2.2 岗位会商为什么不能照搬
+
+岗位会商页面同时有：
+
+- 左侧任务 / 意图 / 流程图；
+- 中间某个节点的对话（`PositionNodeChat`）；
+- 右侧配置抽屉；
+- **以及一个页面级单例沙箱**，它是对话区的**兄弟节点**，不在 `PositionNodeChat` 的 ThreadContext 里面。
+
+因此：
+
+1. 沙箱拿不到节点对话内部的 `thread`，除非节点主动上报；
+2. 若把每次流式 thread 写进**页面级 `useState`**，整页（任务卡、意图、流程图、对话）都会按流式频率重渲染，主线程会被打爆；
+3. 页面必须自己决定「开 / 关 / 抑制自动再开 / 切节点时清理」，不能让多个子组件各自 `setOpen`。
+
+所以岗位会商采用：
+
+```text
+对话子组件探测 + 上报
+  → 页面壳统一打开唯一 ArtifactFileDetail
+  → 流式 thread 走外部 store，只让沙箱子树订阅
+```
+
+### 2.3 和「多智能体会商 Step2 沙箱」的区别
+
+仓库里还有 `frontend-web/docs/roundtable-step2-sandbox-progress.md`，那是另一套圆桌 Step2 沙箱进度文档，**不是**岗位会商这条链路。对接岗位会商时以本文为准。
+
+---
+
+## 3. 用户可见的正确行为（验收标准）
+
+重做或对接完成后，下列行为必须全部成立（用户感知对齐普通对话页）：
+
+| # | 行为 | 说明 |
+| --- | --- | --- |
+| A | 步骤条刚出现「写入文件」时，沙箱应已打开 | **不必等**步骤条上出现文件名 |
+| B | 沙箱源码边写边滚；消息列表也实时出字 | 不能整页卡死、不能「生成完一口气刷」 |
+| C | content 先于 path 时：先临时名打开，path 到了再改名 | 不闪屏、不重挂 |
+| D | 同轮第二次同路径 `write_file`（重新生成） | 沙箱清空并重新流式 |
+| E | 整轮结束后自动切 Markdown 预览 | 「正在生成，完成后自动预览」消失 |
+| F | 用户手动关闭后，同一次写入不再自动弹 | 下一轮新写入仍可自动开 |
+| G | 切岗位 / 切节点 / 新会话 / 切历史 | 沙箱关掉且不串内容 |
+
+**不要误判的正常现象：**
+
+- 流式期间沙箱停在「源码 / 编辑」视图，结束后才切「预览」——这是 `ArtifactFileDetail` 对 markdown/html 的既定行为，与普通对话页相同，**不是**打开时机 bug。
+- 步骤条长时间显示「写入文件」、没有路径，但沙箱已经打开并在滚动——content-first 模型下这是**预期**。
+

+- **内容怎么更新**：子组件持续上报 thread 快照 → 页面壳 store → 只有沙箱子树重渲染。
+
+---
+
+## 5. 职责划分：谁拥有什么状态
+
+### 5.1 页面壳必须拥有
+
+| 状态 / 能力 | 为什么必须在页面壳 |
+| --- | --- |
+| `sandboxArtifact` | 唯一预览目标；切节点时要清 |
+| `closedSandboxKeyRef` | 用户关过后的抑制；跨子组件生命周期 |
+| `sandboxThreadStore` | 流式内容通道；不能进大页面 state |
+| `closeSandbox()` | 切岗位 / 切节点 / 新会话统一入口 |
+| 唯一 `ArtifactFileDetail` | 避免双实例、关闭失效、深度异常 |
+
+### 5.2 对话子组件必须拥有
+
+| 状态 / 能力 | 作用 |
+| --- | --- |
+| `autoPreviewRunArmedRef`（armed） | 只有本轮用户发送后才允许自动开 |
+| `autoPreviewBaselineCallKeysRef`（baseline） | 忽略发送前已有的历史 write_file |
+| `activeWriteFilePreviewRef` | 记录当前打开的 previewKey / path / toolCallId |
+| `autoPreviewedArtifactKeyRef` | 同一次 identity 去重，避免每 chunk 重复上报 |
+| `latestStreamingWriteFile` | 从 streaming messages 探测可预览的 write |
+| `onThreadSnapshot` 上报 | 把 thread 喂给页面壳 |
+
+### 5.3 明确禁止
+
+1. 在 `PositionNodeChat` 内再挂一套 `ArtifactFileDetail`。  
+2. 让步骤条组件直接 `setOpen(true)` 作为岗位会商主路径（对照普通页可以，岗位会商不行）。  
+3. 把 `onThreadSnapshot` 落到 `PositionRoundtablePage` 的 `useState`。  
+4. 用「整个 threadId」做关闭抑制。  
+5. 用「path 相同」复用 `previewKey`。
+
+---
+
+## 6. 对接接口详解
+
+### 6.1 `PositionArtifactPreview`
+
+```ts
+type PositionArtifactPreview = {
+  threadId: string;          // 必填：LangGraph thread id
+  path: string;              // 必填：真实路径，或 write-file: 虚拟 URL，或临时文件名路径
+  name: string;              // 展示名（文件名）
+  mimeType: string | null;   // 如 text/markdown；帮助预览语言判断
+  previewKey?: string;       // 强烈建议：一次交付身份，推荐 `${messageId}:${toolCallId}`
+  auto?: boolean;            // true = 流式自动打开；缺省/false = 用户点击打开
+};
+```
+
+字段说明：
+
+| 字段 | 详细含义 |
+| --- | --- |
+| `threadId` | 沙箱用来匹配 `onThreadSnapshot` 的线程；也对关闭抑制键有贡献 |
+| `path` | 传给 `ArtifactFileDetail.filepath`。流式阶段通常是 `write-file:...` 虚拟 URL；落盘后的手动打开可以是真实 artifacts 路径 |
+| `name` | UI 展示用；临时名阶段可能是 `未命名文件.md` |
+| `mimeType` | 当 path 还不稳定时，帮助把语言判成 markdown/html，避免落成 TEXT |
+| `previewKey` | **一次交付的身份**。同一次 tool call 的 path 升级要保持不变；新的 tool call 必须变 |
+| `auto` | 自动打开才走关闭抑制；手动打开应清抑制 |
+
+### 6.2 `onPreviewArtifact(artifact)` —— 对话 → 页面
+
+页面壳 `handlePreviewArtifact` 当前逻辑顺序：
+
+1. 校验 `threadId`、`path`，缺则 toast 并 return。  
+2. 计算 `artifactKey = sandboxCloseKey(artifact)`。  
+3. 若 `artifact.auto === true` 且 `closedSandboxKeyRef.current === artifactKey` → **抑制，直接 return**。  
+4. 清 `closedSandboxKeyRef`（手动打开或新的自动打开）。  
+5. `ArtifactsContext.select(path, true)` + `setOpen(true)`。  
+6. 判断是否同一预览 / 是否仅 path upgrade：  
+   - `isSamePreview`：threadId + path + previewKey 全同 → 不重复 setState。  
+   - `isPathUpgrade`：previewKey 相同、path 不同 → 更新 artifact，**不要**再折叠右侧抽屉。  
+7. 若不是 same preview：  
+   - `setSandboxArtifact(artifact)`；  
+   - **同步** `sandboxArtifactRef.current = artifact`（关键！flush 会立刻读 ref）；  
+   - `sandboxSnapshotAppliedAtRef.current = 0`（允许立刻推首帧内容）。  
+8. 若 store 里已有别的 thread 快照，先 `publish(null)`。  
+9. 若 `latestNodeThreadSnapshotRef` 的 threadId 匹配，立刻 `queueSandboxThreadSnapshot`。  
+10. 非 path upgrade 时 `setRightPanelOpen(false)`。
+
+`sandboxCloseKey`：
+
+```ts
+if (artifact.previewKey) {
+  return `${artifact.threadId}:write:${artifact.previewKey}`;
+}
+return `${artifact.threadId}:${normalizePreviewArtifactPath(artifact.path)}`;
+```
+
+`ArtifactFileDetail` 的 React `key` 必须用这个 key：  
+**新 previewKey → 组件重挂 → 视觉上「清空再生成」。**
+
+### 6.3 `onThreadSnapshot({ threadId, thread })` —— 对话 → 页面
+
+每次 `thread` 引用变化（消息 chunk 到达）子组件都会调：
+
+```ts
+onThreadSnapshot?.({ threadId: activeThreadId, thread });
+```
+
+页面壳应：
+
+1. 计算 `signature = sandboxThreadSignature(thread)`（用 isLoading、messages 长度、最近 write_file 的 path/content 长度/尾部等拼签名，用于去重）。  
+2. 写入 `latestNodeThreadSnapshotRef`（即使沙箱还没开，打开瞬间也要用）。  
+3. 若当前没有打开的沙箱，或打开的沙箱 threadId 不一致 → **只更新 ref，不 publish**。  
+4. 若一致 → `queueSandboxThreadSnapshot`（前沿节流后 `store.publish`）。
+
+### 6.4 虚拟 URL 与正文读取
+
+流式阶段 path 形如：
+
+```text
+write-file:${sourcePath}?message_id=${messageId}&tool_call_id=${toolCallId}&language=markdown
+```
+
+`loadArtifactContentFromToolCall`：
+
+1. 解析 URL 的 `message_id`、`tool_call_id`；  
+2. 在 `thread.messages` 里找对应 AI message 的 tool call；  
+3. 返回 `toolCall.args.content`。
+
+结论：
+
+- 沙箱跟的是 **tool call 身份**，不是磁盘文件是否已经写完；  
+- 没有真实 path 也能显示正文；  
+- 临时文件名只影响展示名和语言猜测。
+
+### 6.5 对话子组件 → 页面壳的其它相关回调
+
+| 回调 | 用途 |
+| --- | --- |
+| `onPreviewArtifact` | 打开 / 更新沙箱 |
+| `onThreadSnapshot` | 推送流式 thread |
+| 页面壳 `closeSandbox` 传给 `ArtifactFileDetail.onClose` | 用户点关闭 |
+
+手动从流程图 / 产物列表打开时，也可以直接调 `handlePreviewArtifact`（通常不带 `auto`，或不带 previewKey）。
+
+---
+
+## 7. 打开沙箱的完整步骤
+
+### 7.1 武装（arm）：只有「本轮用户提交」才允许自动开
+
+在 `PositionNodeChat.handleSubmit` 真正 `sendMessage` 之前：
+
+```text
+activeWriteFilePreviewRef = null
+autoPreviewBaselineCallKeysRef = writeFileCallKeys(thread.messages)  // 历史 write 的 messageId:toolCallId
+autoPreviewRunArmedRef = true
+→ sendMessage(...)
+```
+
+发送失败要把 `armed` 设回 `false`。
+
+为什么要 baseline？
+
+线程里往往已经有上几次问答写过的 `write_file`。如果只看「messages 里有没有 write_file」，一提问就会把旧文件再打开一次。baseline 的含义是：**只有这次提交之后新出现的 tool call 才能自动开沙箱**。
+
+### 7.2 探测 `write_file`：不要等完整 path
+
+`write_file` 参数是一整段 JSON 流，**键顺序由模型决定**。
+
+| 模型吐参顺序 | 步骤条表现 | 错误做法的后果 |
+| --- | --- | --- |
+| path / description 先到，再 content | 很快显示描述和文件名 | 普通对话页常见；等 path 也能开 |
+| **content 先到，最后才 path** | 长时间只有「写入文件」，文件名很晚才出现 | 若硬等完整 path，沙箱会晚几十秒甚至一分钟 |
+
+岗位会商报告类 agent **经常是第二种**。
+
+`latestStreamingWriteFile` 规则：
+
+1. 倒序扫描 AI messages 的 `tool_calls`；  
+2. 工具名是 `write_file` 或 `str_replace`；  
+3. **有完整扩展名的 path**（`hasCompleteArtifactExtension`）→ 用真实路径；  
+4. **尚无可用 path，但 `write_file` 的 content 已有非空字符** → 临时文件名：  
+   - 正文头像 HTML → `未命名文件.html`  
+   - 否则 → `未命名文件.md`  
+5. `str_replace` 必须等真实 path（它改已有文件）；  
+6. 组装：  
+   - `key = messageId:toolCallId`  
+   - `path = write-file:虚拟URL`（write_file）或真实 path（str_replace）  
+   - `mimeType`：markdown 则 `text/markdown`
+
+为什么扩展名必须完整？
+
+流式 path 会经历 `/a/b/report.m` → `/a/b/report.md`。若在 `.m` 时就当真实文件打开，预览语言可能被永久判成 TEXT。
+
+### 7.3 上报 effect 的四个门闩
+
+自动上报 `onPreviewArtifact` 前必须同时满足：
+
+1. `thread.isLoading === true`  
+2. 探测到 streaming artifact，且其 key **不在** baseline  
+3. 已有 `previewThreadId`  
+4. `autoPreviewRunArmedRef === true`
+
+然后处理 previewKey：
+
+```text
+若与 activePreview 是同一次 tool call（含 tool-start 前缀兼容）
+  → 复用旧 previewKey   // 用于临时名 → 真实 path
+否则
+  → previewKey = 新的 messageId:toolCallId
+```
+
+去重键：
+
+```text
+`${previewThreadId}:${previewKey}:${sourcePath}`
+```
+
+把 `sourcePath` 算进去，是为了：**同 previewKey 下临时名变成真实 path 时，还要再报一次**（path upgrade），但不会每来一个 content chunk 都报。
+
+### 7.4 线程绑定竞态（不要误 disarm）
+
+首轮对话常出现：
+
+1. 用户发送（本地 draft threadId / 稍后 SDK 创建真实 id）；  
+2. 流已经开始、armed=true；  
+3. 会话 API 把 `node.threadId` 从 `null` 写成真实 id。
+
+这是「本节点绑定自己的新线程」，**不是**切节点。若绑定 effect 无脑清空 armed / baseline，首轮会永远开不了沙箱。
+
+正确：识别 `isOwnThreadBinding`（同 nodeKey、旧 threadId 为空、新 threadId 等于当前 boundThreadId）时 **直接 return，不清 armed**。
+
+### 7.5 path upgrade（改名）≠ 第二次交付
+
+同一次 tool call：
+
+```text
+T1  content 到达 → path=未命名文件.md, previewKey=msg:tc1 → 打开
+T2  真实 path 到达 → path=/mnt/.../报告.md, previewKey=msg:tc1 → 只改名
+```
+
+页面壳看到相同 previewKey、不同 path → `isPathUpgrade`：
+
+- 更新 `sandboxArtifact`；  
+- **不**重挂（React key 仍基于 previewKey）；  
+- **不**再折叠右侧抽屉。
+
+### 7.6 同路径二次写入（重新生成）
+
+同一次问答里模型可能：
+
+```text
+1) write_file → 步骤条「写入文件」→ 打开沙箱
+2) 再 write_file 同 path，description=「重新生成优化版…」
+```
+
+这是**两次 tool call**，必须两个 previewKey。  
+若错误地「path 相同就复用 previewKey」：
+
+- 步骤条出现第二条；  
+- 沙箱 React key 不变；  
+- 用户看到「重新生成了，但沙箱没变化」。
+
+正确：身份只看 tool call。
+
+### 7.7 时序总图（content-first）
+
+```text
+T0    用户发送 → armed=true，拍 baseline
+T1    步骤条出现「写入文件」（尚无 path）
+T1+   args.content 首字符到达 → 临时名打开沙箱，源码开始滚动
+      … store 约每 160ms 推一次 thread 快照 …
+T2    args.path 拼完整（含 .md）→ path upgrade，标题改真实文件名（不重挂）
+T3    write 结束 / isLoading=false → 自动切 Markdown 预览
+```
+
+### 7.8 时序总图（同轮二次写入）
+
+```text
+T1  write_file#1 → previewKey=msg:tc1 → 打开沙箱 A
+T2  #1 结束（可能短暂切预览）
+T3  write_file#2（同 path，新 description）→ previewKey=msg:tc2
+    → key 变 → 组件重挂清空 → 跟 #2 重新流式
+```
+
+---
+
+## 8. 关闭沙箱的完整步骤
+
+### 8.1 用户手动关闭
+
+`closeSandbox()` 应做：
+
+1. `closedSandboxKeyRef = sandboxCloseKey(current)` —— 抑制**这一次**自动再开；  
+2. 关闭 `ArtifactsContext.open`（若开着）；  
+3. 清节流定时器、pending 快照；  
+4. `sandboxSnapshotAppliedAtRef = 0`；  
+5. `sandboxArtifactRef = null` + `setSandboxArtifact(null)`；  
+6. `sandboxThreadStore.publish(null)`。
+
+抑制与 path upgrade 的关系：
+
+- 关掉临时名面板后，同一次 tool call 升级真实 path **仍被抑制**（同一 previewKey）——符合「用户不要看这次」；  
+- 下一次新的 `write_file`（新 previewKey）**可以**再自动开。
+
+### 8.2 场景切换时强制关闭
+
+以下操作应先调用 `closeSandbox()`，避免串台：
+
+- 切岗位；  
+- 切节点；  
+- 切收口阶段；  
+- 新建会话；  
+- 切换历史会话。
+
+是否写入 `closedSandboxKeyRef` 可按产品决定；至少必须清面板和 store。
+
+### 8.3 错误的抑制粒度（历史坑）
+
+若做成「关过一次就整个 thread 不再自动开」：
+
+- 第一次实时开正常；  
+- 用户关掉；  
+- 再问一次 → 同 thread 被永久抑制 → 看起来像「第二次不实时 / 要等生成完」。
+
+正确粒度：**单次交付的 `sandboxCloseKey`（含 previewKey）**。
+
+---
+
+## 9. 步骤条与沙箱的关系
+
+### 9.1 步骤条从哪来
+
+步骤条由 `MessageList` → `message-group.tsx` 渲染 tool call：
+
+- 标题：优先 `args.description`；没有则 i18n 兜底「写入文件」；  
+- 子行：有 `args.path` 才显示路径；  
+- 普通对话页还会在「有 path + autoOpen」时自己 `select/setOpen`。
+
+岗位会商里，步骤条**仍然只负责展示**；打开沙箱走 `onPreviewArtifact`，不要让两套逻辑抢。
+
+### 9.2 对照表
+
+| 你看到的步骤条 | 含义 | 沙箱应处于 |
+| --- | --- | --- |
+| 仅「写入文件」，无路径 | tool call 已开始；path/description 可能还没流到 | **应已打开**（临时名），源码在滚 |
+| 「写入文件」+ 路径 | path 已可用 | 已打开；若刚从临时名升级则只改名 |
+| 带自定义 description 的标题 + 路径 | 模型给了 description | 同上 |
+| 第二条「重新生成…」+ 同路径 | 新的 write_file（新 toolCallId） | **应重挂**并重新流式 |
+| 顶部「正在生成，完成后自动预览」 | 仍在 code 视图 | 正常，等 isLoading 结束切预览 |
+| 生成结束，出现文件卡片 / present_files | 工具结果已落 | 通常已是预览模式；可手动再点开 |
+
+### 9.3 常见误解
+
+**误解 1：**「步骤条出现文件名 = 打开沙箱的正确时机」  
+→ 错。那是 path 到达的时机。content-first 时正确打开时机更早：content 首字节 / 工具调用已开始。
+
+**误解 2：**「步骤条还在写『写入文件』，沙箱却开了，是 bug」  
+→ 通常不是。两边数据源相同，但沙箱允许无 path 打开，步骤条标题可能还没 description。
+
+**误解 3：**「等生成完从编辑切预览 = 沙箱打开晚了」  
+→ 错。那是 `ArtifactFileDetail` 的 viewMode 策略。
+
+---
+
+## 10. 流式内容如何进入沙箱（性能关键）
+
+### 10.1 为什么不能用页面 `useState` 存线程快照
+
+错误写法：
+
+```ts
+setSandboxThreadSnapshot(snapshot) // 页面级 useState
+```
+
+后果：
+
+- 消息 chunk 约每 30ms 一次，节流后仍约 6 次/秒；  
+- 每次都重渲染整页：任务卡、意图结果、流程图、节点对话……；  
+- 主线程占满 → 消息列表停绘、沙箱冻住；  
+- 纯尾随 `setTimeout(160)` 会被饿死，十几秒不 flush。
+
+这同时解释了两个历史现象：
+
+1. 「沙箱打开了但内容不更新」；  
+2. 「修完节流后整页更卡、消息也不实时」——因为节流终于开始真正 setState 了。
+
+### 10.2 正确做法：外部 store + 子树订阅
+
+```ts
+createSandboxThreadStore()
+  subscribe / getSnapshot / publish
+
+SandboxThreadProvider
+  useSyncExternalStore(store.subscribe, store.getSnapshot)
+  → ThreadContext.Provider value={{ thread, isMock:false }}
+  → ArtifactFileDetail
+```
+
+页面壳本身**不**因 snapshot 变化而重渲染；只有 Provider 及其子树重渲染。
+
+### 10.3 节流必须是前沿（leading-edge）
+
+`SANDBOX_SNAPSHOT_MIN_INTERVAL_MS = 160`：
+
+```text
+queue(snapshot):
+  pending = snapshot
+  if 距上次 publish >= 160ms:
+      立刻 flush（同步 publish）
+  else:
+      若没有在途 timer，则 setTimeout(剩余时间) 做补尾
+flush:
+  清 timer
+  校验 pending.threadId === sandboxArtifactRef.threadId
+  publish(pending)
+```
+
+**不要**改回：
+
+```ts
+if (timer != null) return;
+timer = setTimeout(flush, 160);
+```
+
+那是纯尾随；忙主线程下会假死。
+
+### 10.4 signature 去重
+
+`sandboxThreadSignature` 用最近 write_file 的 path、content 长度、content 尾 32 字等拼签名。  
+store.publish 时若 threadId+signature 未变，则不通知订阅者，减少无效渲染。
+
+### 10.5 打开瞬间的首帧
+
+`handlePreviewArtifact` 里往往会立刻 `queueSandboxThreadSnapshot(latestSnapshot)`。  
+此时 React 的 `setSandboxArtifact` 可能还没提交，若 flush 只读旧的 `sandboxArtifactRef`，会因 threadId 不匹配把首帧丢掉。
+
+所以打开新预览时必须：
+
+```ts
+sandboxArtifactRef.current = artifact; // 同步
+sandboxSnapshotAppliedAtRef.current = 0;
+```
+
+---
+
+## 11. 与普通对话页的对照
+
+| 点 | 普通对话页 | 岗位会商 |
+| --- | --- | --- |
+| 谁触发打开 | `message-group` 内 `artifacts.select` | 子组件 `onPreviewArtifact` → 页面壳 |
+| 是否要求 path | 是（有 path 才自动开） | 否（write_file + content 可临时名开） |
+| thread 从哪来 | 同树 ThreadContext | `onThreadSnapshot` + 外部 store |
+| 关闭抑制 | 主要靠 ArtifactsContext / 用户操作 | `closedSandboxKeyRef` 按 previewKey |
+| 同 path 重写 | 依赖新的 tool call / 选择逻辑 | **必须**新 previewKey 以重挂 |
+| 结束后切预览 | ArtifactFileDetail 同一套 | 同一套 |
+
+对齐目标是**用户感知一致**，不是代码路径完全相同。
+
+普通对话页自动开的核心条件（对照用）：
+
+```ts
+artifacts && isLoading && isLast && autoOpen && autoSelect && path && !result
+```
+
+它也要求 path，所以 content-first 时普通页同样会偏晚——只是很多主聊天示例 agent 先吐 path，观感更好。岗位会商报告 agent 更常 content-first，所以必须做临时名提前开。
+
+---
+
+## 12. 重做页面时的必守规则
+
+按优先级：
+
+1. **流式 thread 快照禁止进页面级 `useState`** → 用 store + `useSyncExternalStore`。  
+2. **节流用前沿 + 补尾**，不要纯尾随 timer。  
+3. **不要等完整 path 才开**；`write_file` + content 即可临时名打开。  
+4. **扩展名完整前不要把 path 当最终 path**。  
+5. **previewKey 按 tool call，不按 path**。  
+6. **打开时同步写 `sandboxArtifactRef`，并重置节流时间戳**。  
+7. **主路径扫描 `thread.messages`，不要只靠 `onToolStart`**。  
+8. **path upgrade 保持 previewKey，不要当第二次交付**。  
+9. **关闭抑制按 sandboxCloseKey，不要按整 thread**。  
+10. **沙箱单例在页面壳；子组件只上报**。  
+11. **本节点 threadId 回写不要 disarm**。  
+12. **「结束后才切预览」不要当打开 bug 去「修」掉共享组件**，除非产品明确要求边生成边渲染 Markdown（需单独评估性能）。
+
+---
+
+## 13. 历史问题与根因（务必读）
+
+下面每个都在真实联调里出现过。重做时若踩中，优先回来对照。
+
+### 13.1 沙箱要等文件名出来才开（晚几十秒）
+
+**现象：** 步骤条早就「写入文件」，沙箱很晚才开；普通对话页对比显得「实时」。  
+
+**根因：** 探测逻辑硬等完整 `path`；而该 agent 先流 `content`、最后才流 `path`。  
+
+**修复：** content 首批字符即可用临时名打开；path 到了再 upgrade。
+
+### 13.2 沙箱打开了，内容冻住，生成完才灌满
+
+**现象：** 面板开了，但里面一直是空/旧内容；日志里 queue 很多，flush 很少。  
+
+**根因：** 纯尾随 160ms 定时器在忙主线程下被饿死。  
+
+**修复：** 前沿节流——到期就在流回调里同步 flush。
+
+### 13.3 修完「内容更新」后，整页卡顿、消息也不实时
+
+**现象：** 沙箱开始更新了，但页面更卡，消息列表也「攒到最后刷」。  
+
+**根因：** flush 走的是页面 `useState`，每 160ms 整页重渲染。以前 timer 饿死时反而「不卡」。  
+
+**修复：** 快照改外部 store，只让沙箱子树订阅。
+
+### 13.4 第二次「重新生成」步骤有了，沙箱不变
+
+**现象：** 同轮第二条二条 write 步骤，沙箱仍显示第一次完整结果。  
+
+**根因：** 用「path 相同」复用了第一次 previewKey，React key 不变，组件不重挂。  
+
+**修复：** previewKey 只按 tool call；同 path 新 call 必须新 key。
+
+### 13.5 第一次实时，关掉后再问就不实时
+
+**现象：** 关过沙箱后，下一轮要等生成完才开，或不开。  
+
+**根因：** 抑制绑在整个 threadId，或把 path upgrade / 新 call 误判成同一次。  
+
+**修复：** 抑制键 = `sandboxCloseKey(previewKey)`；仅抑制那一次交付。
+
+### 13.6 首轮永远不开
+
+**现象：** 新建节点第一次提问，armed 后很快又不满足条件。  
+
+**根因：** `node.threadId` 从 null 回写真实 id 时，绑定 effect 误 disarm。  
+
+**修复：** `isOwnThreadBinding` 时不清 armed。
+
+### 13.7 预览变成纯文本
+
+**现象：** 明明是 md，却按 TEXT 打开。  
+
+**根因：** 在 `.m` 阶段就当完整 path；或临时名没有 `.md` / 没传 language、mimeType；或 path 带空格。  
+
+**修复：** `hasCompleteArtifactExtension`；临时名带扩展名；URL 加 `language=markdown`；path trim。
+
+### 13.8 依赖 onToolStart，线上偶发不开
+
+**现象：** 本地偶发正常，联调经常不开。  
+
+**根因：** 后端 StreamBridge / worker 可能过滤 tools/events 类 stream mode。  
+
+**修复：** 主路径必须是 messages 里渐进出现的 `tool_calls`；onToolStart 只能当补充。
+
+---
+
+## 14. 排障手册（按症状）
+
+排障时建议先看 Chrome Performance / React 重渲染是否整页抖，再看消息里 tool_calls 的 args 是 path-first 还是 content-first。
+
+### 14.1 沙箱开得很晚
+
+检查顺序：
+
+1. `latestStreamingWriteFile` 是否仍要求完整 path？  
+2. armed 是否被 threadId 回写清掉？  
+3. 是否命中 `closedSandboxKey`？  
+4. 新 call 是否被 baseline 当成历史？  
+5. `previewThreadId` 是否为空（线程还没绑上）？
+
+### 14.2 打开了但内容空白 / 冻住
+
+1. 快照是否进了页面 useState？  
+2. 节流是否纯尾随？  
+3. `SandboxThreadProvider` 是否拿到带 messages 的 thread？  
+4. 虚拟 URL 的 message_id / tool_call_id 是否对得上？  
+5. 打开时 `sandboxArtifactRef` 是否同步？（首帧是否被 drop）  
+6. signature 是否因实现错误一直不变，导致 publish 被去重？
+
+### 14.3 整页卡、消息列表也不实时
+
+1. 搜页面壳是否还有 `setSandboxThreadSnapshot` / 类似大对象 state。  
+2. 是否在每 chunk `console.debug` 打大对象（DevTools 打开时更卡）。  
+3. 是否错误地让页面壳订阅了 store（页面壳不应 `useSyncExternalStore` 这份 store；只有 Provider 订）。
+
+### 14.4 重新生成不刷新
+
+1. 第二次 write 的 toolCallId 是否变了？  
+2. previewKey 是否仍用 path 复用？  
+3. `ArtifactFileDetail` 的 `key=` 是否基于 sandboxCloseKey/previewKey？
+
+### 14.5 关后再问异常
+
+1. 打印 `closedSandboxKeyRef` 与新 artifact 的 sandboxCloseKey。  
+2. 确认新一轮 send 时 armed/baseline 已重置。  
+3. 确认抑制不是整 thread。
+
+### 14.6 语言 / 预览模式不对
+
+1. 看打开时的 path / mimeType / language 查询参数。  
+2. 确认不是在扩展名不完整时打开。  
+3. 确认「源码→预览」发生在 isLoading false 之后（属正常）。
+

+
+## 15. 对接自测清单
+
+重做页面后至少跑完：
+
+### 功能
+
+- [ ] 首轮：步骤条「写入文件」出现时，沙箱是否已开并开始出字？  
+- [ ] content-first agent：无文件名阶段是否也能开？  
+- [ ] path 到达后：是否只改名、不整页闪、不重挂？  
+- [ ] 同轮第二次同路径 write：是否清空并重新流式？  
+- [ ] 结束后是否自动切 Markdown 预览？  
+- [ ] 手动点步骤条路径 / 产物卡片：能否打开正确文件？  
+
+### 关闭与抑制
+
+- [ ] 流式中手动关闭：本次是否不再自动弹？  
+- [ ] 关闭后再发一轮新问题：是否仍可自动开？  
+- [ ] path upgrade 是否不会绕过「用户刚关闭」的抑制？  
+
+### 场景切换
+
+- [ ] 切节点：沙箱关闭，旧内容不残留。  
+- [ ] 切岗位：同上。  
+- [ ] 新建会话 / 切历史：同上。  
+
+### 性能
+
+- [ ] 流式中消息列表是否实时出字？  
+- [ ] 页面是否明显掉帧 / 卡死？  
+- [ ] React DevTools 中，大页面壳是否在每 160ms 整页 update？（不应）
+

+
+## 附录 A：给对接同学的一页纸摘要
+
+1. 页面壳只挂一个沙箱；子组件只调用 `onPreviewArtifact` / `onThreadSnapshot`。  
+2. 自动打开时机 ≈ 步骤条出现「写入文件」时，而不是出现文件名时。  
+3. `write_file` 可以没有 path：临时名打开，path 到了再改名。  
+4. 流式 thread 进外部 store，进页面 state 会卡死。  
+5. 节流要前沿；previewKey 看 tool call；关闭抑制看 sandboxCloseKey。  
+6. 同路径重新生成 = 新 previewKey = 沙箱重挂。  
+7. 出问题先对照第 13、14 节，再看代码索引第 17 节。

+# 沙箱统一写作管线：可实现开发方案
+
+> 状态：设计稿；本文件只定义实施方案，不包含本轮业务代码改动。  
+> 覆盖范围：普通沙箱 Markdown、深度研究 `report.md`、现有 Markdown 编辑器的选区/段落改写。
+
+## 1. 目标与结论
+
+目标不是再增加一个“AI 写作页面”，而是将现有的四类能力统一为一个安全、可流式、可追溯的**文档改写管线**：
+
+1. Markdown 编辑器选区改写；
+2. Markdown 编辑器段落改写；
+3. 深度研究报告的局部候选改写；
+4. 沙箱中 Markdown 文件的全文改写。
+
+该管线负责固定原文版本、构造上下文、逐 token 输出、校验 Markdown、生成可核验 diff、按策略提交，以及在全文覆盖时保存可撤销版本。
+
+结论：需求可行，现有工程已有足够的复用基础：
+
+- `frontend-web/src/open-canvas/components/artifact/MarkdownAiEditor.tsx` 已具备局部改写弹窗与人工“替换/插入/重试/追问”交互。
+- `frontend-web/src/open-canvas/hooks/useWritingRewrite.ts` 与 `frontend-web/src/open-canvas/api/rewrite.ts` 已具备 SSE 文本流消费。
+- `offline-backend-20260512/backend/app/gateway/routers/writing.py` 已具备模型流式读取实现。
+- `offline-backend-20260512/backend/app/gateway/routers/deep_research.py` 已具备报告哈希、候选内容和用户确认应用机制。
+- `frontend-web/src/components/workspace/messages/message-list.tsx`、`MessageGroup.tsx` 已可承载普通对话的工具步骤条、流式消息和文件卡片。
+- `frontend-web/src/pages/deep-research/DeepResearchWorkbench.tsx` 已经通过虚拟消息把研究进度接入普通 `MessageList`。
+
+因此应该复用这些基础，建设一个执行内核；不能为全文改写另建独立聊天列表或独立写作流。
+
+## 2. 产品边界与交互策略
+
+### 2.1 支持范围
+
+第一版仅对 `.md`、`.markdown` 文件显示“AI 全文改写”按钮。
+
+不支持 PDF、DOCX、HTML、图片和二进制文件；不在改写过程中发起新的联网搜索；超大文件不静默截断后覆盖，而是提示用户选择章节改写。
+
+### 2.2 范围、模式和提交策略
+
+| 入口 | 文本范围 | 管线模式 | 提交策略 | 展示位置 |
+| --- | --- | --- | --- | --- |
+| 编辑器气泡菜单 | 当前选区 | `selection` | `preview_only` | 现有改写预览弹窗 |
+| 编辑器段落菜单 | 当前段落 | `paragraph` | `preview_only` | 现有改写预览弹窗 |
+| 深度研究“改写第一段/章节” | 被解析出的报告片段 | `report_section` | `manual_apply` | 普通消息列表候选稿 + 确认卡 |
+| 文件右上角“AI 全文改写” | 当前完整 Markdown | `document` | `auto_commit_after_validation` | 普通消息列表步骤条 + 右侧沙箱 |
+
+统一内核中的枚举：
+
+~~~python
+class RewriteMode(str, Enum):
+    SELECTION = "selection"
+    PARAGRAPH = "paragraph"
+    REPORT_SECTION = "report_section"
+    DOCUMENT = "document"
+
+class CommitPolicy(str, Enum):
+    PREVIEW_ONLY = "preview_only"
+    MANUAL_APPLY = "manual_apply"
+    AUTO_COMMIT_AFTER_VALIDATION = "auto_commit_after_validation"
+~~~
+
+这三类策略必须严格区分：
+
+- `preview_only`：只生成候选，前端编辑器确认后才改本地 TipTap 文档；不写真实沙箱文件。
+- `manual_apply`：后端保留基准哈希和候选片段，用户点确认后才将该片段应用进研究报告。
+- `auto_commit_after_validation`：全文生成完成并校验通过后，后端进行一次带哈希校验的原子覆盖；同时保存可撤销版本。
+
+### 2.3 局部编辑器：保持当前体验
+
+现有文件：
+
+- `frontend-web/src/open-canvas/components/artifact/MarkdownAiEditor.tsx`
+- `frontend-web/src/open-canvas/hooks/useWritingRewrite.ts`
+- `frontend-web/src/open-canvas/api/rewrite.ts`
+- `offline-backend-20260512/backend/app/gateway/routers/writing.py`
+
+局部改写仍然是：
+
+1. 选中文字或打开段落菜单；
+2. 选择润色、扩写、缩写、改写等动作；
+3. 在现有弹窗中流式出现候选；
+4. 用户手动选择替换、插入、重试或继续追问。
+
+不要让局部改写每次都往普通消息列表插完整步骤条，否则频繁编辑会淹没聊天历史。它只共享底层管线，不共享全文改写的消息展示方式。
+
+需要补充本地版本保护：发起请求时保存当前完整编辑器文本哈希、选区 `from/to` 和选区文本；用户点击“替换原文”前再次检查该范围仍匹配。若用户已修改原文，提示“原文已变化，请重新生成候选稿”，禁止将过期候选替换到错误位置。
+
+### 2.4 右上角“AI 全文改写”
+
+宿主文件：
+
+- `frontend-web/src/components/workspace/artifacts/artifact-file-detail.tsx`
+
+新增独立图标按钮，位置在右上角文件操作区，靠近保存、复制、下载一类操作。它**不能**替代页面中间当前 Sparkles 编辑模式：
+
+| 控件 | 职责 |
+| --- | --- |
+| 中部 Sparkles/编辑模式 | 打开 `MarkdownAiEditor`，处理选区和段落 |
+| 新增右上角 AI 全文改写 | 对整个 Markdown 发起后台全文重写任务 |
+
+建议显示条件：
+
+~~~ts
+const canUseFullDocumentRewrite =
+  isMarkdownFile &&
+  canEditArtifact &&
+  !isSkillFile &&
+  !isMock &&
+  !useWriteFileStreaming &&
+  !hasLocalEdits;
+~~~
+
+若 `hasLocalEdits` 为真，按钮置灰并提示“请先保存当前修改后再进行全文改写”。后端全文任务从真实文件读取快照，不能在用户本地还有未保存修改时读取旧版本并最终覆盖新修改。
+
+用户体验：
+
+1. 点击按钮，打开简洁配置弹窗。
+2. 弹窗显示文件名、原文字数；用户填写改写要求、选择模型、选择风格。
+3. 点击开始，左侧普通消息列表创建一组步骤条。
+4. 右侧沙箱自动切到源码视图，先显示“正在准备临时草稿，原文件尚未修改”。
+5. 新 Markdown 从空临时草稿开始逐 token 写入右侧代码区域。
+6. 校验通过后，后端原子替换真实内容；前端再同步真实 Artifact 缓存。
+7. 左侧保留最终对比总结、查看 diff 按钮和撤销按钮。
+
+任务进行中，同一个文件的保存、直接编辑、局部编辑和再次全文改写必须禁用；其他文件不受影响。
+
+### 2.5 深度研究报告的约束
+
+普通 Markdown 和深度研究报告使用同一管线，但不能使用同一上下文策略：
+
+| 能力 | 普通沙箱 Markdown | 深度研究 report.md |
+| --- | --- | --- |
+| 输入上下文 | 原文 + 用户指令 | 原文 + 当前会话已选资料 |
+| 联网 | 不联网 | 不联网 |
+| 事实约束 | 不新增无依据事实 | 只能引用已选资料，禁止编造 |
+| 引用校验 | 可选 | 必须校验来源 ID 白名单 |
+| 最终存储 | Artifact 文件 | 研究 session 的 `report_markdown` |
+| 局部改写 | 编辑器确认 | 现有确认卡片 |
+
+深度研究右侧的 `report.md` 是由 `ResearchSandboxPanel.tsx` 以虚拟 `write_file` 方式展示的；它不能当作普通磁盘 Artifact 直接写入。全文任务必须通过研究 session 更新 `report_markdown`，并使 `report_html` 缓存失效。
+
+## 3. 总体架构
+
+~~~mermaid
+flowchart LR
+  A["MarkdownAiEditor<br/>选区 / 段落"] --> P
+  B["ArtifactFileDetail<br/>AI 全文改写"] --> P
+  C["DeepResearch<br/>局部 / 全文"] --> P
+
+  P["Document Rewrite Pipeline<br/>冻结版本 → 构造上下文 → 流式生成<br/>校验 → 差异总结 → 按策略提交"]
+
+  P --> I["InlineDocumentSource"]
+  P --> F["ArtifactDocumentSource"]
+  P --> R["DeepResearchReportSource"]
+
+  P --> E["可恢复 SSE 事件 / Job"]
+  E --> L["普通 MessageList"]
+  E --> S["右侧沙箱临时草稿"]
+  P --> V["内容哈希、版本快照、原子提交"]
+~~~
+
+设计原则：
+
+1. 纯执行内核不依赖 FastAPI、路由、用户身份或操作系统路径。
+2. 鉴权、线程路径解析、研究 session 获取只在 `app` 层的来源适配器中完成。
+3. 完整文档任务使用持久化后台 Job；局部弹窗可维持单次 SSE，避免过度持久化。
+4. 全文流式过程中只写临时草稿；真实内容只在最终 compare-and-swap 成功时改变。
+
+不要直接把现有完整“AI 写作 Agent”塞进改写按钮。那个流程适合从主题写新文章，可能包含大纲、资料和章节生命周期；本需求是严格以当前文档为基准改写。第一版复用它的流式视觉表达和消息列表能力，但使用专门的文档改写执行内核。
+
+## 4. 后端模块设计
+
+### 4.1 目录与职责
+
+建议新增：
+
+~~~text
+offline-backend-20260512/backend/
+├─ packages/harness/deerflow/
+│  ├─ document_rewrite/
+│  │  ├─ __init__.py
+│  │  ├─ models.py                 # 请求、事件、校验、差异领域模型
+│  │  ├─ ports.py                  # Source / Model / Store 协议
+│  │  ├─ pipeline.py               # 统一编排，不导入 app.*
+│  │  ├─ prompt_builder.py          # 普通与深度研究提示词
+│  │  ├─ validation.py              # Markdown / 引用 / 截断检查
+│  │  └─ diff_summary.py            # 字数、标题、块、引用差异
+│  └─ persistence/
+│     └─ document_rewrites/
+│        ├─ base.py
+│        ├─ model.py
+│        └─ sql.py
+├─ app/gateway/
+│  ├─ routers/document_rewrites.py
+│  ├─ document_rewrite_sources.py
+│  └─ document_rewrite_executor.py
+└─ packages/harness/deerflow/persistence/migrations/versions/
+   └─ <next_revision>_document_rewrites.py
+~~~
+
+`packages/harness/deerflow/document_rewrite` 不能导入 `app.*`，以符合项目 harness→app import firewall。`app/gateway/document_rewrite_sources.py` 负责把已鉴权的 Artifact/研究会话包装成内核端口。
+
+### 4.2 来源端口
+
+~~~python
+class DocumentSource(Protocol):
+    async def read_snapshot(self) -> DocumentSnapshot: ...
+    async def read_current_hash(self) -> str: ...
+    async def commit_if_unchanged(
+        self,
+        *,
+        expected_hash: str,
+        content: str,
+        metadata: CommitMetadata,
+    ) -> CommitResult: ...
+    async def restore_if_unchanged(
+        self,
+        *,
+        expected_hash: str,
+        content: str,
+    ) -> CommitResult: ...
+~~~
+
+三种实现：
+
+| 适配器 | 使用场景 | 读取方式 | 提交方式 |
+| --- | --- | --- | --- |
+| `InlineDocumentSource` | 选区/段落候选 | 前端编辑器快照 | 不提交 |
+| `ArtifactDocumentSource` | 普通 Markdown | 复用 Artifact 权限与虚拟路径解析 | 同目录临时文件 + `os.replace` |
+| `DeepResearchReportSource` | 研究报告 | session `report_markdown` + 已选来源 | 数据库哈希条件更新 |
+
+`ArtifactDocumentSource` 必须复用 `app/gateway/routers/artifacts.py` 中已有的线程访问校验、虚拟路径解析逻辑，绝不允许请求体传入任意本机绝对路径。
+
+### 4.3 持久化 Job、事件和版本
+
+全文改写使用持久化 Job，参考 `app/gateway/deep_research_job_executor.py` 的后台任务、租约、取消监听和事件重放模式。
+
+#### document_rewrite_jobs
+
+| 字段 | 作用 |
+| --- | --- |
+| `id` | `drw_xxx` Job ID |
+| `user_id` | 发起人 |
+| `source_kind` | `artifact` / `deep_research_report` |
+| `thread_id`、`artifact_path` | 普通文件来源 |
+| `research_session_id` | 研究报告来源 |
+| `presentation_thread_id` | 普通消息列表归属 |
+| `mode`、`commit_policy` | 范围和提交语义 |
+| `instruction`、`style`、`model_name` | 用户配置 |
+| `base_sha256` | 原文冻结哈希 |
+| `draft_content`、`draft_sha256` | 临时流式草稿 |
+| `status`、`stage` | 生命周期 |
+| `validation_json`、`diff_summary_json` | 可展示结果 |
+| `committed_sha256` | 成功提交后的哈希 |
+| `error_message`、时间字段 | 错误、审计、取消 |
+
+#### document_rewrite_events
+
+至少包含 `job_id`、`seq`、`event_type`、`stage`、`payload_json`、`created_at`。`seq` 用于断线重连时通过 `after_seq` 重放。
+
+不必将每个 token 单独入库：每 250ms 或每积累 4KB 持久化一次 `draft_content`；状态转换、警告、完成、冲突、取消必须立即写事件。重连时先发送最新草稿快照，再发送快照序号后的增量事件。
+
+#### document_rewrite_versions
+
+保存真实全文覆盖前的原文版本，字段包含 `job_id`、`source_identity`、`version_no`、`content`、`sha256`、`reason`、`created_at`。初版每个文档保留最近 20 个版本即可。
+
+索引要求：
+
+- `(user_id, presentation_thread_id, created_at DESC)`：恢复历史消息。
+- 真实来源标识 + 活跃状态：防止同一文档并行两个全文改写。
+
+### 4.4 Job 状态机
+
+~~~mermaid
+stateDiagram-v2
+  [*] --> queued
+  queued --> snapshotting
+  snapshotting --> generating
+  generating --> validating
+  validating --> comparing
+  comparing --> committing
+  committing --> completed
+  completed --> reverted
+
+  queued --> cancelled
+  generating --> cancelled
+  snapshotting --> failed
+  generating --> failed
+  validating --> failed
+  committing --> conflict
+  committing --> failed
+~~~
+
+状态约束：
+
+- 同一真实文档只允许一个活跃 Job。
+- 生成期间取消、异常、断线，真实文档绝不能变化。
+- 提交前重新读取当前哈希；与 `base_sha256` 不一致时进入 `conflict`，草稿保留但不覆盖。
+
+### 4.5 API 与 SSE 契约
+
+创建全文任务：
+
+~~~http
+POST /api/document-rewrites
+Content-Type: application/json
+~~~
+
+普通 Artifact 请求：
+
+~~~json
+{
+  "source": {
+    "kind": "artifact",
+    "thread_id": "thread_xxx",
+    "path": "/mnt/user-data/outputs/report.md"
+  },
+  "presentation_thread_id": "thread_xxx",
+  "mode": "document",
+  "instruction": "统一为正式行业分析语气，减少重复，不新增外部事实",
+  "style": "formal_analysis",
+  "model_name": "system_default"
+}
+~~~
+
+深度研究请求：
+
+~~~json
+{
+  "source": {
+    "kind": "deep_research_report",
+    "session_id": "drs_xxx"
+  },
+  "presentation_thread_id": "collector_thread_xxx",
+  "mode": "document",
+  "instruction": "重新组织全文逻辑，保留全部可用引用",
+  "style": "formal_analysis",
+  "model_name": "system_default"
+}
+~~~
+
+其他接口：
+
+~~~text
+GET  /api/document-rewrites/{job_id}
+GET  /api/document-rewrites/{job_id}/stream?after_seq=42
+POST /api/document-rewrites/{job_id}/cancel
+POST /api/document-rewrites/{job_id}/undo
+GET  /api/document-rewrites?presentation_thread_id={thread_id}
+~~~
+
+SSE 事件：
+
+| 事件 | 关键数据 | 前端动作 |
+| --- | --- | --- |
+| `job_started` | 文件名、模式 | 建立步骤条 |
+| `snapshot_fixed` | 原文字数、哈希 | 完成“固定原文版本” |
+| `requirements_resolved` | 模型、风格、要求 | 完成“理解改写要求” |
+| `rewrite_delta` | `delta`、累计字符数 | 追加右侧临时草稿 |
+| `validation_started` | 校验项 | 进入校验步骤 |
+| `validation_completed` | passed、warnings | 显示校验结果 |
+| `comparison_ready` | `DiffSummary` | 渲染总结数据 |
+| `commit_started` | 无 | 显示安全替换中 |
+| `committed` | 最终哈希、版本 ID | 刷新真实文件缓存 |
+| `completed` | 完整结果 | 固化历史步骤条 |
+| `conflict` / `error` / `cancelled` | 原因 | 恢复原文显示，不保存草稿 |
+
+局部改写兼容方案：
+
+- `POST /api/writing/rewrite` 的请求和 SSE 格式先不变。
+- `writing.py` 内部逐步把 prompt、模型流、基础 Markdown 校验下沉给统一管线的 `preview_only` 分支。
+- 深度研究 `/sessions/{id}/rewrite/stream` 和确认候选接口也先保持 URL、前端行为不变，再内部复用 `manual_apply` 分支。
+
+这样可以先交付全文改写，不会一次性破坏已有编辑器和深度研究流程。
+
+### 4.6 模型、提示词与校验
+
+管线只依赖一个流式模型端口：
+
+~~~python
+class StreamingRewriteModel(Protocol):
+    async def stream_text(
+        self,
+        *,
+        messages: list[BaseMessage],
+        model_name: str | None,
+    ) -> AsyncIterator[TextChunk]: ...
+~~~
+
+第一版可以有两个 adapter：
+
+- 普通文档复用 `writing.py` 的 chat model `astream`；
+- 深度研究复用 `deep_research.py` 使用的 `DeerFlowCompletionBackend.stream_complete`。
+
+先统一编排，不强制立即统一所有模型配置实现。
+
+普通 Markdown 系统约束：
+
+~~~text
+仅根据原文与用户要求改写，不联网，不补充未给出的事实。
+保留有效链接、代码块、表格、标题语义和用户明确要求保留的内容。
+只输出完整 Markdown 正文；不得输出解释、前缀或“改写如下”。
+~~~
+
+深度研究额外约束：
+
+~~~text
+不得联网。事实、数字、结论和引用只能来自当前 session 已选资料。
+只允许使用给出的 source_id；资料不足时保持谨慎表述，禁止自行补全。
+~~~
+
+校验规则：
+
+| 类别 | 硬失败 | 告警但允许完成 |
+| --- | --- | --- |
+| 正文 | 空文档、仅空白、无可见内容 | 改写后与原文完全一致 |
+| Markdown | 未闭合围栏、明确截断 | 标题层级跳级、章节数明显减少 |
+| 深度研究来源 | 未选来源 ID、非法引用 | 引用数量下降、可能需核验的数字断言 |
+
+## 5. 安全提交、对比与撤销
+
+### 5.1 临时草稿不等于真实文件
+
+用户视觉上看到“先清空再逐 token 写入”，但真实文件的处理必须是：
+
+1. 读取原文并保存内容哈希、版本快照。
+2. 右侧只展示内存/Job 中的 `draft_content`。
+3. 生成完成后做校验和 diff。
+4. 提交前再次读取真实来源，并比较 `SHA-256`。
+5. 哈希一致才原子替换；否则进入冲突，不覆盖。
+
+普通 Artifact 使用同目录临时文件、刷盘和 `os.replace`；深度研究通过数据库事务内的“旧哈希条件更新”提交。任何失败、取消或断流都保留真实原文。
+
+### 5.2 撤销
+
+撤销流程：
+
+1. 读取该 Job 的 `before_full_rewrite` 快照。
+2. 确认当前真实内容哈希仍等于该 Job 的 `committed_sha256`。
+3. 若用户在改写后又手工编辑，返回冲突，不盲目覆盖。
+4. 先保存当前内容为 `before_undo` 版本。
+5. 原子恢复旧版本，Job 状态改为 `reverted`，消息列表卡片同步显示“已撤销”。
+
+### 5.3 结构化 DiffSummary
+
+后端产出结构化差异，前端仅渲染，避免生成空泛结论：
+
+~~~ts
+type DiffSummary = {
+  sourceDisplayName: string;
+  instruction: string;
+  modelName: string;
+  originalCharCount: number;
+  rewrittenCharCount: number;
+  charChangeRatio: number;
+  changedBlockCount: number;
+  headings: {
+    added: string[];
+    removed: string[];
+    reordered: string[];
+    levelWarnings: string[];
+  };
+  citations?: {
+    beforeCount: number;
+    afterCount: number;
+    retainedCount: number;
+    removedIds: string[];
+    invalidIds: string[];
+  };
+  requestedOptimizations: string[];
+  validationWarnings: string[];
+};
+~~~
+
+推荐总结展示：
+
+~~~text
+已完成《新能源汽车市场分析报告》的整体改写。
+
+- 改写范围：全文；要求为“统一正式分析语气、减少重复”；模型：默认模型。
+- 数量变化：原文 8,260 字，改写后 8,110 字，减少 1.8%；调整 14 个内容块。
+- 结构变化：标题层级保持不变；未新增或删除一级标题。
+- 已执行的优化：按要求合并重复表述、统一语气、调整段落衔接。
+- 保留情况：保留 35 条已选来源引用，未新增外部来源。
+- 风险提示：无。
+
+[查看前后对比] [撤销到改写前版本]
+~~~
+
+“已执行的优化”仅来自用户要求和可计算的结构差异；不能无依据宣称“文章更专业、更严谨”。
+
+## 6. 前端实现设计
+
+### 6.1 新增模块
+
+~~~text
+frontend-web/src/core/document-rewrite/
+├─ types.ts
+├─ api.ts
+├─ sse.ts
+├─ use-document-rewrite-job.ts
+├─ document-rewrite-provider.tsx
+└─ document-rewrite-presentation.ts
+
+frontend-web/src/components/workspace/document-rewrite/
+├─ DocumentRewriteDialog.tsx
+├─ DocumentRewriteProgressStep.tsx
+├─ DocumentRewriteSummaryCard.tsx
+└─ DocumentDiffDialog.tsx
+~~~
+
+职责：
+
+| 模块 | 职责 |
+| --- | --- |
+| `api.ts` | 创建、查询、取消、撤销 Job |
+| `sse.ts` | SSE 解析、`after_seq` 重连 |
+| `use-document-rewrite-job.ts` | Job 状态、草稿、rAF 合并 token |
+| Provider | 同时向文件面板与消息列表提供同一任务状态 |
+| `DocumentRewriteDialog` | 改写要求、模型、风格配置 |
+| ProgressStep | 普通消息列表内的五步步骤条 |
+| SummaryCard | 结构化总结、diff、撤销动作 |
+| DiffDialog | 原文与改写后双栏/行级对比 |
+
+模型选择使用项目已有的 `tdesign-react` 选择组件，放在全文改写配置弹窗中；局部编辑器保留当前模型传递方式，后续再统一选择器。
+
+### 6.2 流式平滑：每帧合并 delta
+
+不能因为 SSE 是 token 流就每 token 调一次 `setState`。应当网络层完整读取、渲染层按动画帧合并：
+
+~~~ts
+const pendingDeltaRef = useRef("");
+const frameRef = useRef<number | null>(null);
+
+function onRewriteDelta(delta: string) {
+  pendingDeltaRef.current += delta;
+  if (frameRef.current !== null) return;
+
+  frameRef.current = requestAnimationFrame(() => {
+    const pending = pendingDeltaRef.current;
+    pendingDeltaRef.current = "";
+    frameRef.current = null;
+    setDraftContent((previous) => previous + pending);
+  });
+}
+~~~
+
+完成、失败、取消前必须 flush 最后一段缓存。右侧代码编辑器只消费 `draftContent`；真实 Artifact 查询缓存直到 `committed` 事件才更新。
+
+### 6.3 ArtifactFileDetail 改造
+
+在 `artifact-file-detail.tsx` 增加：
+
+~~~ts
+type DocumentRewriteTarget =
+  | {
+      kind: "artifact";
+      threadId: string;
+      path: string;
+      presentationThreadId: string;
+    }
+  | {
+      kind: "deep_research_report";
+      sessionId: string;
+      presentationThreadId: string;
+    };
+~~~
+
+改造步骤：
+
+1. 加入右上角全文改写图标按钮和 `DocumentRewriteDialog`。
+2. 有活跃任务时强制 `viewMode = "code"`。
+3. 内容优先级为：`activeRewrite.draftContent ?? draftContent ?? artifactContent`。
+4. 活跃任务中代码只读，禁用保存、局部编辑和重复全文改写。
+5. 收到 `committed` 后用现有 `useUpdateArtifactContent` 或等价 Query cache 更新，使真实文件立即同步。
+6. 收到 `conflict/error/cancelled` 时废弃临时草稿显示，回到真实文件内容。
+
+### 6.4 ResearchSandboxPanel 接入
+
+相关文件：
+
+- `frontend-web/src/pages/deep-research/ResearchSandboxPanel.tsx`
+- `frontend-web/src/pages/deep-research/useReportSandbox.ts`
+- `frontend-web/src/pages/deep-research/DeepResearchWorkbench.tsx`
+
+改造：
+
+1. `ResearchSandboxPanel` 为虚拟 `report.md` 传入 `kind: "deep_research_report"` target。
+2. `useReportSandbox` 接受 `externalDraftOverride`：
+
+~~~ts
+const visibleReport = activeDocumentRewrite?.isActive
+  ? activeDocumentRewrite.draftContent
+  : reportMarkdown;
+~~~
+
+3. 流式期间只显示临时草稿，不提前写 session 报告。
+4. `committed` 后刷新/替换 session 的 `report_markdown`；失败后恢复旧报告。
+5. 当前“改写第一段 → 候选消息 → 确认应用”逻辑继续保留，不因全文改写而改变。
+
+### 6.5 普通消息列表接入
+
+复用：
+
+- `frontend-web/src/components/workspace/messages/message-list.tsx`
+- `frontend-web/src/components/workspace/messages/MessageGroup.tsx`
+- `DeepResearchWorkbench.tsx` 中的虚拟消息注入模式。
+
+`DocumentRewritePresentationProvider` 按 `presentation_thread_id` 读取 Job 历史并投影为：
+
+1. 用户消息：“AI 全文改写《xxx.md》”；
+2. AI 工具调用：`document_rewrite_progress`；
+3. AI 富消息：`document_rewrite_summary`。
+
+`MessageGroup.tsx` 增加 `document_rewrite_progress` 分支，渲染 `DocumentRewriteProgressStep`。最终摘要渲染 `DocumentRewriteSummaryCard`，其内含“查看前后对比”和“撤销”。
+
+全文步骤固定为：
+
+| 步骤 | 展示内容 |
+| --- | --- |
+| 固定原文版本 | 文件名、原文字数、快照已保存 |
+| 理解改写要求 | 改写目标、模型、风格 |
+| 流式重写 Markdown | 正在写入右侧 xxx.md、累计字数 |
+| 校验文档 | 非空、标题、围栏、截断；报告还含来源检查 |
+| 对比原文并生成说明 | 差异、风险、撤销入口 |
+
+步骤条必须在完成后保留，不能因为流结束被隐藏。
+
+## 7. 核心执行伪代码
+

+~~~
+
+## 8. 实施顺序
+
+### 阶段 A：后端内核与安全基础
+
+1. 新增领域模型、来源端口、校验、确定性 diff。
+2. 新增 Job、事件、版本数据表与 migration。
+3. 参考深度研究 executor 完成后台任务、取消、SSE 重放。
+4. 实现普通 Artifact 读取、哈希比较、原子提交和撤销 API。
+5. 编写接口测试。
+
+验收：可以通过 API 对普通 Markdown 创建全文任务；取消、失败、冲突均不改原文件；成功后可撤销。
+
+### 阶段 B：普通沙箱全文 UI
+
+1. 新增 `core/document-rewrite` 前端状态、SSE、rAF hook。
+2. 改 `ArtifactFileDetail`：右上角按钮、配置弹窗、临时草稿、禁用态。
+3. 接入普通 `MessageList` 的步骤条、总结卡、diff 和撤销。
+4. 支持刷新后恢复 Job 状态与已完成历史。
+
+验收：右侧可平滑逐 token 写入；完成后替换真实 Markdown；左侧步骤和总结保留；撤销成功恢复。
+
+### 阶段 C：深度研究接入
+
+1. 实现 `DeepResearchReportSource`。
+2. 由 `ResearchSandboxPanel` 传入报告 target。
+3. `useReportSandbox` 支持外部临时草稿。
+4. 对深度研究添加引用白名单校验。
+5. 保持现有报告局部候选确认卡不变，再逐步下沉公共 prompt/校验逻辑。
+
+验收：报告全文改写不触发联网搜索，不允许新来源；局部报告改写依然先确认再应用。
+
+### 阶段 D：局部改写内核迁移
+
+1. 保持 `/api/writing/rewrite` 契约不变。
+2. 将 `writing.py` 转为 `InlineDocumentSource + preview_only` 的兼容 facade。
+3. 给 `useWritingRewrite` 增加原文快照失效检查。
+4. 回归替换、插入、重试、继续追问。
+
+## 9. 测试与验收
+
+建议新增后端测试：
+
+~~~text
+offline-backend-20260512/backend/tests/
+├─ test_document_rewrite_pipeline.py
+├─ test_document_rewrite_api.py
+├─ test_document_rewrite_versions.py
+└─ test_document_rewrite_deep_research.py
+~~~
+
+必须覆盖：
+
+- Job 状态、SSE 顺序和断线恢复；
+- 空输出、围栏不闭合、截断、非法深度研究引用；
+- 同一文件并发任务；
+- 提交前手工修改导致的冲突；
+- 取消/异常不改真实文件；
+- 正常撤销、撤销前手工编辑导致的冲突；
+- 旧 `/api/writing/rewrite`、深度研究 `/rewrite/stream` 兼容回归。
+
+前端必须覆盖：
+
+- 多个 delta 在一帧合并，最终内容不丢失；
+- `committed` 前 Artifact 缓存不被临时草稿污染；
+- 失败/取消/冲突后右侧恢复原文；
+- 活跃任务禁用同文件编辑、保存、重复改写；
+- 刷新后历史步骤条与总结仍存在；
+- 深度研究虚拟 `report.md` 可用全文改写；
+- 局部编辑器原文变化后不能应用过期候选。
+
+执行基线：
+
+~~~powershell
+cd offline-backend-20260512/backend
+$env:PYTHONPATH = "."
+uv run --no-sync pytest tests/test_document_rewrite_pipeline.py -v
+uv run --no-sync pytest tests/test_document_rewrite_api.py -v
+uv run --no-sync ruff check app packages/harness
+
+cd ../../frontend-web
+pnpm typecheck
+pnpm build
+~~~
+
+## 10. 风险控制
+
+| 风险 | 控制措施 |
+| --- | --- |
+| 用户误以为真实文件已经清空 | 明确显示“临时草稿，原文件尚未修改” |
+| 流式显示仍然卡顿 | 网络完整读取 + `requestAnimationFrame` 合并渲染 |
+| 改写中用户手动编辑 | `SHA-256` compare-and-swap，冲突即拒绝覆盖 |
+| 输出 Markdown 不完整 | 非空、围栏、截断和标题检查 |
+| 深度研究幻觉 | 来源白名单、禁止联网、引用 ID 校验 |
+| 文档过大 | 第一版拒绝并提示按章节改写，不隐式截断 |
+| 局部编辑污染聊天历史 | 局部只在编辑器弹窗展示，不创建完整步骤条 |
+| 历史记录只存在浏览器内存 | 全文 Job/Event/Diff 持久化，按展示线程恢复 |
+
+## 11. 复用点清单
+
+| 现有实现 | 在新方案中的用途 |
+| --- | --- |
+| `MarkdownAiEditor.tsx` | 保留局部编辑菜单、预览弹窗、确认动作 |
+| `useWritingRewrite.ts` | 保留局部流控制，增加快照失效保护 |
+| `open-canvas/api/rewrite.ts` | 保持兼容，逐步接入统一内核 |
+| `routers/writing.py` | 复用当前模型流式读取，抽取 prompt/流逻辑 |
+| `routers/deep_research.py` | 复用报告来源、哈希候选、来源约束 |
+| `deep_research_job_executor.py` | 复用后台 Job、取消、事件重放模式 |
+| `artifact-file-detail.tsx` | 复用沙箱文件操作、代码/预览、缓存同步 |
+| `useUpdateArtifactContent` | 完成后更新普通 Artifact 缓存 |
+| `ResearchSandboxPanel.tsx` | 复用研究报告的右侧沙箱宿主 |
+| `useReportSandbox.ts` | 加入临时草稿覆盖显示 |
+| `MessageList.tsx / MessageGroup.tsx` | 复用普通消息步骤条、总结消息、文件卡片能力 |
+| `DeepResearchWorkbench.tsx` | 复用向普通消息列表投影过程事件的模式 |
+
+## 12. 完成定义
+
+完成后应满足：
+
+1. 局部编辑依旧是编辑器弹窗中的人工确认操作。
+2. 全文改写在普通消息列表展示完整且不隐藏的步骤条。
+3. 右侧沙箱可平滑地逐 token 展示临时 Markdown 草稿。
+4. 任何中断、取消、校验失败和冲突都不损坏真实文件。
+5. 完成后用户可以看到量化差异、结构变化、来源保留和风险提示。
+6. 普通 Markdown 与深度研究报告都可全文改写，但研究报告绝不绕过已选来源约束。
+7. 每一次真实全文覆盖都有版本快照，并且能够安全撤销。
