# CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## Project Overview
This is a customized offline deployment of **DeerFlow** — a LangGraph-based AI super agent platform. The repo contains two sub-projects:
- `offline-backend-20260512/backend/` — Python backend (FastAPI Gateway + LangGraph agent runtime)
- `frontend-web/` — Vite + React 19 frontend (TypeScript, pnpm)
Managed together via shell scripts in `scripts/`.
## Commands
### Full Application (from repo root)
```bash
./scripts/start-all.sh # Start backend + frontend as background daemons
./scripts/stop-all.sh # Stop both
./scripts/restart-all.sh # Restart both
./scripts/status.sh # Check running status
```
Logs and PID files are written to `.runtime/logs/` and `.runtime/pids/`.
### Backend Only (from `offline-backend-20260512/backend/`)
```bash
make install # Install Python dependencies (uv)
make dev # Run Gateway API with hot-reload on port 8001
make gateway # Run Gateway API without reload
make test # Run all tests: PYTHONPATH=. uv run pytest tests/ -v
make lint # Lint with ruff
make format # Format with ruff
```
Run a single test file:
```bash
PYTHONPATH=. uv run pytest tests/test_<feature>.py -v
```
### Frontend Only (from `frontend-web/`)
```bash
pnpm install # Install dependencies
pnpm dev # Start Vite dev server on port 5174
pnpm build # Production build
pnpm typecheck # TypeScript type checking (tsc --noEmit)
```
## Service Ports
| Service | Port | Notes |
|---------|------|-------|
| Backend (Gateway API) | 8001 | FastAPI + LangGraph runtime |
| Frontend (Vite) | 5174 | React SPA |
Frontend connects to backend via env vars `VITE_BACKEND_BASE_URL` and `VITE_LANGGRAPH_BASE_URL` (injected by `scripts/start-frontend.sh`).
## Architecture
### Backend
The backend (`offline-backend-20260512/backend/`) is split into two layers:
- **`packages/harness/deerflow/`** — publishable agent framework (`deerflow.*` imports): LangGraph lead agent, middleware chain, sandbox, tools, MCP, memory, models, skills. **Never imports from `app.*`.**
- **`app/`** — application layer (`app.*` imports): FastAPI Gateway routers, IM channel integrations (Feishu, Slack, Telegram, DingTalk).
The **Lead Agent** (`deerflow/agents/lead_agent/`) is the single LangGraph graph entry point. It wraps a middleware chain (~18 middlewares assembled in strict order) around LLM calls, handling: thread isolation, sandbox lifecycle, uploads, memory, plan mode, vision, subagent delegation, and loop detection.
**Middleware order matters** — middlewares are appended in a fixed sequence; `ClarificationMiddleware` must always be last. See `offline-backend-20260512/backend/CLAUDE.md` for the full ordered list.
**Harness → App import firewall** is enforced by `tests/test_harness_boundary.py` (runs in CI).
**Workflow Studio** (`deerflow/workflows/` + `/api/workflows*`) is a second, independent execution path beside the lead agent: a persisted DAG scheduler that runs published workflow graphs, streams a durable event log over SSE, and supports human-input pauses, cancellation, and crash recovery via lease reclaim. Coze Studio supplies the canvas UI only; LangGraph is used only *inside* an `agent`/`skill` node. Master switch and all limits live in `config.yaml` → `workflows`. See the backend `CLAUDE.md`「Workflow Studio」and `docs/WORKFLOW_STUDIO_BACKEND_DEV_ZH.md`.
### Frontend
The frontend (`frontend-web/`) is a React 19 + Vite SPA:
- **Routing**: React Router v7; top-level routes in `src/pages/PageRoutes.tsx`, workspace sub-routes in `src/pages/WorkspaceRoutes.tsx`
- **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)
- **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). **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). **`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」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`. Tests: `tests/test_task_buttons.py`.
- **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). A premature SSE close (SDK treats it as success and restores the send button while the backend run is still occupying the thread) is recovered by `confirmOrRejoin`: hold the stop button, `joinStream` the live run, and on 409 auto-reconnect instead of a fake AI bubble. `sse_consumer` no longer ends a resumable (`on_disconnect=continue`) stream on a false-positive `is_disconnected()`.
- **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 stay isolated even though they share one taskId; **xdfx** passes a third `actionId` so it filters by `metadata.actionId` too, partitioning chat records per 行动 — `useChatsBase` derives it from `TaskContext.partitionByAction`) + 新建对话; the `…/chats` index (`TaskFxIndexResolver`) opens the latest task thread or 新建. The right `:thread_id` host differs by business: **rwfx** → `TaskFxChat` (`AgentChatPage taskGate`) = full workspace (non-`lite`): 目的树闸门 panel + 清除记录 (placed under 新建对话); **xdfx** → also `TaskFxChat` (same 目的树闸门 query+display, same `purpose_detail_url`) but workspace passed `lite`, **plus its own「清除记录」button** (`ActionClearButton`, under 新建对话) that deletes **by 行动id**: opening its confirm dialog first runs a「行动历史是否存在」pre-check (`fetchActionHistoryExists`; query endpoint `task_deeplink.action_history_url` is **address-TBD** — empty ⇒ unknown, does **not** block the delete; once a definite「无历史」comes back it disables 确认清除), then deletes via the **shared** delete endpoint `task_deeplink.delete_url` (migrated to `dropSixOrSevenData`, used by **both** rwfx + xdfx — Six=6BF/rwfx, Seven=7BF/xdfx): `deleteTaskPurpose(id, {idKind})` sends rwfx `?taskId=` (omits actionId) / xdfx `?actionId=` (omits taskId) — the unused param is **absent from the URL**, not null. `deleteTaskPurpose` + `fetchActionHistoryExists` live in `core/auth/task-purpose.ts`. **3qfx** → `TaskBindChat` (`AgentChatPage taskBind`, `lite`) = 1:N list only, no gate, and 新建对话 **auto-sends** the task opening text (`taskAutoSendText`; gate businesses send it via the gate's 开始问答 instead). **rwfx auto-starts the first Q&A when the 任务目的 query returns empty** (`TaskPurposePanel autoStartWhenEmpty`, threaded from the rwfx `TaskFxChat` only), **but gated by the 3q precheck**: on entering the rwfx workspace `RwfxSqGateProvider` (`task-components/rwfx-sq-gate.tsx`, wraps the workspace, rwfx only) calls `fetchSqReportStatus(taskId)` — `incomplete`(3q 无数据) pops the「3q 未完成,是否前往 3qfx」dialog AND **holds the auto-send**; the question is only sent when the user picks「暂不」(or dismisses — i.e. does NOT go to 3q analysis), while「前往 3qfx」navigates and discards the send. `complete`/`unknown` send immediately (no dialog). The panel's auto-start calls `useRwfxSqGate().gateStart(onStart)` instead of `onStart()`; the manual「开始问答」/覆盖确认 path is unchanged (ungated). This replaced the old standalone `RwfxSqReportGate` (which popped the same dialog but did not gate the auto-send). The 目的树闸门 (`TaskPurposePanel`) defaults **collapsed** and now keeps only 弹框查看 + 开始问答; the former jump buttons (编辑/下一步/3q详情/切换三情/弹框查看) all moved to the **configurable bottom 快捷跳转 bar** (`TaskJumpBar`, red 红底白字 buttons, right-aligned) driven by 按钮管理 — see the 按钮管理 bullet. `TaskPurposeDialog` (exported from `TaskPurposePanel`) backs both the gate zoom and the bottom bar's `purpose`-type button. `chatBasePath` keeps the post-send URL rewrite + new-chat button in the task-management context. Backend config `task_deeplink` (`config.yaml`, surfaced by `GET /api/public/config/task-deeplink`, mirrored in `core/auth/task-deeplink-config.ts`) adds `action_test`/`action_detail_url`/`detail_3q_url` + `mock.action_detail`. Any failure (no consumer URL / fetch error / unmapped goPath / unresolvable action id / no configured agent) silently falls back to the default home.

- **iframe 嵌入模式 (外部系统用 iframe 套用深链问答/会商)** — 三个**按标签页**开关,全部由深链 URL 参数开启、存进同一份 `sessionStorage` 会话(`embed.session`,键名常量在 `core/embed/embed-session.ts`),跨登录跳转/刷新/页内导航存活,**绝不跨标签污染**同浏览器另开的正常系统页。核心隔离手法:用 `sessionStorage`(按标签页/浏览上下文隔离,iframe 即便同源也有独立一份)而非 `localStorage`(跨标签共享)。开关:(1) **`?embed=1`(可带 `&theme=`)** — 去全局 chrome(`PageLayout` 的 `pageSidebarAllowed && !isEmbedActive()` → 隐藏 Header + PageSidebar)+ 按外部主题色**强制**明/暗:走 next-themes 的 `forcedTheme`(`App.tsx` `AppProviders` 调 `resolveForcedEmbedTheme`,**不写** localStorage `strategy-theme`),离散映射 `dark-blue`/`dark`→深、其余→浅;嵌入侧**绝不**调 `setTheme`/`persistSidebarEnabled`(那俩落 localStorage 跨标签污染,`LoginPage` 据 `readEmbedParam` 跳过)。(2) **`?hideJump=1`** — 隐藏深链底部「快捷跳转」栏 `TaskJumpBar` 的两部分(底部「下一步」等按钮 + 右侧垂直居中悬浮菜单),单智能体问答 + 会商共用该栏,`isJumpBarHidden()` 为真时整条 `return null`。(2.5) **`?hideChrome=1`** — **仅**去全局 chrome(Header 导航栏 + PageSidebar 侧边栏),**不**强制主题、**不**隔离鉴权(区别于 `embed`:只想要一个干净全屏页面,如「大屏绘制」`/page/strategy/dashboard-agent?taskId=…&hideChrome=1`)。新增 `EmbedSession.hideChrome` 字段 + `readHideChromeParam()` + `isChromeHidden()`(取 `embed || hideChrome` 之并),与 `hideJump` 完全对称;`PageRoutes.tsx` 的 `PageLayout` 把 `chromeHidden`(`isChromeHidden() || readHideChromeParam(location.search)==="on"`)并入 `pageSidebarAllowed`,且其**优先级高于** dashboard-agent 路由原本的强制全局 chrome(`forceChromeForDashboardAgent`)。`hideChrome=0` 可显式关闭。(3) **登录用户隔离** — 嵌入态下鉴权/身份键(`deerflow.auth` token、`userInfo`、`login.*`、`tools_token`、maxkey/userDetail token)全部经 `core/auth/scoped-storage.ts` 的 `authStorage()`(嵌入→sessionStorage / 正常→localStorage)读写,使 iframe 里登录的用户与正常登录用户**完全隔离**、互不覆盖;所有 token 读取都过 `getStoredAuth()`/`getAuthorizationHeaderValue()`(API 客户端 `core/api/*` 全走这俩),改中心函数即让全体调用方自动隔离;跨标签账号变更监听 `AuthSyncWatcher`(`core/auth/sync.tsx`)在嵌入态禁用。嵌入会话在 `main.tsx` 渲染前 `syncEmbedSessionFromCurrentUrl()` 同步启用(早于任何鉴权写入,避免首帧 effect 顺序漏写 localStorage);`AppProviders` 的 effect 再按 SPA 导航同步。`embed=0`/`hideJump=0` 可显式关闭。正常(非嵌入)标签页所有 `isXxx()` 恒 false,行为**零变化**。第三个开关 `?isolate=1`(**独立登录会话**)把同一套**登录用户隔离**单独提供给**普通(带 chrome)标签页**——只切换鉴权存储、不去 chrome / 不强制主题 / 不动跳转栏:`authStorage()` 的条件从「仅嵌入」放宽为 `isEmbedActive() || isIsolatedSession()`,`AuthSyncWatcher` 的跨标签监听对嵌入态**或**独立态都即时忽略(handler 内实时判,运行时开关也即刻生效)。除 URL 参数外,**设置 → 外观 →「登录会话」** 有一个 Switch「独立登录会话(本标签页)」运行时切换(`setIsolatedSession`,`appearance-settings-page.tsx`):**开启时先 `migrateAuthToSession()`**(`scoped-storage.ts`,把 localStorage 的受保护键 `deerflow.auth`/`userInfo`/`userId`/`tools_token` + `login.*` 前缀快照搬进 sessionStorage)再翻标志,故无感不登出;此后本标签页登录态独立——别处登录/换号影响不到它,它换号也影响不到别人,但关掉该标签即结束(需重登)。开启给 toast 提示。
