+# AgentScope 2.0 多智能体报告协作工作台——前端实施计划
+
+> 文档状态：待评审、尚未开始编码
+> 编写日期：2026-09-02
+> 目标项目：`F:\react01\deeflow-code\deerflow-server\frontend-web`
+> 视觉与交互参考：`F:\react01\coze-frontend\frontend\apps\coze-studio`
+> 参考页面：`http://localhost:3000/work_flow?space_id=1&workflow_id=wf_88cb9f4c6642`
+> 配套后端计划：`docs/agentscope-多智能体报告协作工作台-后端实施计划.md`
+> 本文只规划新增页面，不修改现有多智能体会商页面，不复用旧 Workflow Studio 执行状态。
+
+## 1. 前端目标
+
+新增独立的「报告协作」工作台。用户可以通过对话提出任意报告需求，查看系统生成的多个协作方案，点击方案卡片在流程图中预览协作结构，确认后观察多智能体执行，并在全过程通过统一对话框提出修改意见。
+
+前端必须满足：
+
+1. 页面采用“左侧对话、右侧流程画布”的固定两栏布局，画布、工具栏、弹窗和抽屉参考 Coze Studio 页面风格。
+2. 消息列表必须复用 DeerFlow 现有 `MessageList`，不复制 Coze 的会话消息实现。
+3. 所有执行过程、AgentScope 团队消息、智能体回复、工具调用及其原始返回、错误、协助卡、返工和最终报告入口都通过现有消息协议按时间顺序显示在左侧对话区，不设置独立执行结果面板，也不另做“阶段摘要”替代实时消息。
+4. 候选方案、流程节点、对话进度和报告使用同一份后端事实，不各自推断状态。
+5. 用户可在规划中、运行中、等待输入和报告完成后继续对话。
+6. 用户协助卡的出现和提交都不能在前端被解释为“节点已经完成”。
+7. 页面刷新、SSE 断线重连、历史会话切换后能恢复到一致状态。
+
+暂定：
+
+- 页面名称：`报告协作`。
+- 路由：`/page/workspace/report-collaboration`。
+- 会话路由：`/page/workspace/report-collaboration/:sessionId`。
+- 默认候选方案数量：3。
+- 点击画布节点时打开覆盖式节点说明抽屉；抽屉只展示节点职责和合同，不展示节点执行结果。
+
+---
+
+## 2. 范围与非目标
+
+### 2.1 本期范围
+
+- 新建、查看、重命名、删除协作报告会话。
+- 使用对话澄清报告需求。
+- 显示 2～3 个候选方案卡片。
+- 卡片与右侧流程图预览联动。
+- 节点说明抽屉：职责、所依据的信息类型、预期产出、工具、资料要求和验收条件。
+- 实时展示节点排队、运行、校验、等待用户、完成、返工、失败和取消。
+- 在左侧对话时间线中直接展示每个智能体的流式文本、团队对话、工具调用和工具返回，并展示审稿意见、报告文件和报告版本。
+- 并行阶段用横向的智能体选择器切换当前查看对象；选择器只控制同一份消息流的聚焦范围，不创建另一套执行结果视图。
+- 运行期间发送补充要求、重新检索、重新分析、节点重跑等指令。
+- 完成后进行报告问答、章节重写、全文润色和版本恢复。
+- 报告模板选择、Markdown 预览、Markdown/Word 下载。
+- 响应式布局、键盘操作、加载反馈和错误恢复。
+
+### 2.2 明确不做
+
+- 不引入 `@coze-workflow/playground` 或 `@coze-arch/coze-design`。
+- 不加载 Coze workflow definition、run 或 node run。
+- 不允许前端拖拽连线后直接改变执行逻辑。
+- 不新增第二套消息气泡、Markdown、引用和文件卡渲染器。
+- 不展示模型原始 chain-of-thought、系统/内部 prompt、密钥和被标记为内部控制信息的字段。
+- 不把用户有权查看的 AgentScope TeamSay、智能体文本、工具调用或工具返回压缩成“正在检索”等摘要卡；这些原始业务消息必须进入复用的 `MessageList`。敏感字段只能按统一脱敏策略替换，不能以摘要替代。
+- 不增加第三栏、常驻详情栏、节点执行结果栏或独立执行时间线。
+- 节点抽屉不展示节点生成正文、工具返回、证据列表、错误堆栈或 attempt 历史；这些过程统一在左侧 `MessageList` 的原生消息/工具步骤中查看。
+- 不改造现有圆桌、多智能体会商、深度研究和 AI 写作页面。
+- 不把浏览器状态作为业务事实源。
+

+## 3. 参考页面行为映射
+
+| 目标行为 | Coze 参考文件 | DeerFlow 目标组件 | 说明 |
+|---|---|---|---|
+| 两栏骨架 | `workflow-studio-layout.tsx` 的面板比例与分隔条 | `ReportCollaborationLayout.tsx` | 左对话、右画布；只保留一条可调整分隔线 |
+| 顶栏 | `workflow-studio-header.tsx` | `ReportCollaborationHeader.tsx` | 替换为会话、模板、报告、停止等操作 |
+| 候选卡片 | `workflow-proposal-cards.tsx` | `ReportPlanCards.tsx` | 点击预览，明确确认后才执行 |
+| 右侧画布 | `workflow-canvas.tsx` | `ReportFlowCanvas.tsx` | 使用 `@xyflow/react` 重建，不引入 Coze Playground |
+| 左侧消息区 | `run-conversation-panel.tsx` | `ReportConversationPanel.tsx` | 外层风格参考 Coze，内部复用 DeerFlow `MessageList` |
+| 节点说明抽屉 | Coze 节点配置面板的视觉与抽屉行为 | `NodeInspectorDrawer.tsx` | 点击画布节点打开，只展示职责与输入输出合同 |
+| 全程执行反馈 | 参考其进度和状态表达 | `AgentStageSelector` + DeerFlow `MessageList` | 选择智能体后直接显示其流式消息、TeamSay、工具调用与返回；不再合成为阶段摘要 |
+| 状态栏 | `connection-status.tsx` | `ConnectionStatusBar.tsx` | 展示连接、重连和事件游标 |
+| 对话历史 | `left-panel-tabs.tsx` | `ConversationSidebarTabs.tsx` | 对话与历史，不增加“节点资源”Tab |
+| 异步反馈 | 规划进度、运行状态 | MessageList 步骤条 + 画布状态 | 操作超过 300ms 必须有反馈 |
+
+主要参考源：

+```
+
+节点抽屉覆盖在右侧画布之上，不占用第三栏：
+
+```text

+```
+
+抽屉明确不展示实际执行结果、生成正文、工具返回、来源明细、错误堆栈或 attempt 时间线；这些信息只在左侧原生消息流中展示。
+
+布局默认值：
+
+- 顶栏高度：56px。
+- 左侧面板：默认 480px，最小 360px，最大 720px。
+- 右侧画布：最小 480px，使用剩余空间。
+- 节点说明抽屉：覆盖画布右侧，建议宽度 420px；关闭后完整归还画布空间。
+- 状态栏：24～28px。
+- 低于 960px：左侧对话和右侧画布改为顶部按钮切换的单面板模式；节点说明仍使用覆盖式 Drawer。
+- 两栏分隔条：支持 pointer 拖动、方向键、Home、End。
+
+### 4.1 原生消息流与并行智能体切换
+
+“复用 `MessageList`”在本页面的含义是复用它现有的 assistant 文本、`tool_calls`、`tool` 消息、引用、文件和协助卡渲染语义；不把 AgentScope 的运行过程先解析成专用步骤条、进度摘要或阶段结果卡。
+
+单个智能体：
+
+- `agent.reply.started` 立即创建一条稳定的 assistant 消息；`message.delta` 持续更新同一 `messageId`，所以用户会先看到流式状态、再看到逐字回复，而不是等待节点结束。
+- 工具调用创建/更新该 assistant 消息的 `tool_calls`；工具返回创建匹配 `tool_call_id` 的原生 `tool` 消息。现有 `MessageGroup` 负责把两者配对显示，不再另写工具过程渲染器。
+- AgentScope TeamSay 作为带 `agentRunId` 的普通 assistant 消息进入同一流，按到达顺序显示。它不是节点完成的证据，节点状态仍由右侧画布和后端状态机决定。
+
+并行智能体：
+
+```text
+多角度并行研究  3/4 进行中
+[ 协调者 ] [ 市场规模 ✓ ] [ 品牌竞争 ● ] [ 海外市场 ● ] [ 政策风险 ! ]
+└──────────────────── 当前选中智能体的原生 MessageList ────────────────────┘
+```
+
+- `AgentStageSelector` 只在并行阶段出现，横向放置在左侧对话区顶部；使用现有图标体系的头像/角色图标、名称、状态文字和非纯颜色状态标识。默认选中第一位已开始运行的成员；用户手动切换后保持选择，不因其他成员返回而抢走阅读焦点。
+- 所有成员的事件都持续接收、按每个 `agentRunId` 持久化和更新，即使当前未选中；切回即可看到完整历史与正在更新的同一条消息，不丢 token、不重新请求、不把结果拼成摘要。
+- 当前选择只将共享用户消息、协调者广播消息和目标成员消息组成一个 `BaseStream<AgentThreadState>` 交给同一个 `MessageList`。切换标签仅切换该视图的消息范围，不改变 run、节点或消息的后端事实。
+- 某成员请求用户协助时，其标签显示“待回复”徽标，选择器显示待处理数；点击徽标切到该成员，原生协助工具消息仍由现有 `MessageList` 协助卡渲染。其他成员可继续运行。
+- 节点抽屉打开某并行成员时，同步聚焦对应标签；抽屉仍只展示合同。用户从抽屉或输入框发送反馈时带 `targetNodeId`/`agentRunId`，后端在安全点生效。
+
+这不是把完整日志另做成调试面板：对话区展示的是模型和工具的真实业务消息；只有 chain-of-thought、内部提示词及按权限必须脱敏的字段不进入该消息流。
+
+### 4.2 页面主要状态
+
+| 状态 | 左侧对话区 | 右侧流程画布 | 主要操作 |
+|---|---|---|---|
+| `empty` | 欢迎语和输入框 | 空态 | 输入需求、选模板 |
+| `clarifying` | 澄清问题和协助卡 | 需求理解节点 | 回答或补充 |
+| `planning` | 用户消息和规划进度 | 骨架或需求图 | 继续补充，等待安全点生效 |
+| `proposal_ready` | 2～3 张方案卡 | 点击卡片预览对应图 | 切换、修改、采用 |
+| `running` | 协调者与成员原生消息、工具过程和用户反馈 | 实时节点状态 | 干预、停止、在对话中要求重跑 |

+
+---
+
+## 6. 数据来源与前端状态
+
+### 6.1 三层状态
+
+前端状态分为：
+
+1. 服务器快照：session、原生 messages、plans、run、nodes、artifacts、report versions；每条消息带稳定的 `agentRunId`、`nodeRunId`、`phaseId` 和可见性标记，其中 artifacts 只用于生成左侧消息卡和报告文件，不形成独立结果面板。
+2. durable SSE reducer：从 `seq` 连续应用事件，更新服务器快照投影。
+3. 纯展示状态：预览中的方案、选中的节点、聚焦的并行 `agentRunId`、两栏宽度、节点抽屉开关、窄屏当前视图和画布位置。
+
+纯展示状态不能改变执行结果。点击卡片只改变 `previewPlanId`；只有点击“采用方案”才改变服务器 `selectedPlanId`。
+
+### 6.2 前端事件包
+
+```ts
+interface CollaborationEvent<T = unknown> {
+  eventId: string;
+  sessionId: string;
+  runId?: string;
+  seq: number;
+  type: string;
+  timestamp: string;
+  data: T;
+}
+```
+
+必须处理：
+
+- 快照先到、事件后到。
+- 事件重复。
+- 事件短暂乱序。
+- SSE 断线后从 `after_seq` 重放。
+- 页面切换时旧连接晚到事件。
+- token delta 多次更新同一消息。
+- TeamSay、assistant 文本、tool-call 参数 delta、tool 返回 delta 分别更新各自稳定消息，不得等节点完成后批量生成摘要。
+- 并行成员的消息可交错到达；Reducer 必须按 `agentRunId + messageId` 更新，而不是按当前被选中的标签丢弃未聚焦成员的事件。
+- 节点重新打开后出现新 attempt。
+
+Reducer 以 `sessionId + runId + seq` 去重；消息行以 `messageId`、工具结果以 `toolCallId`、标签以 `agentRunId` 使用后端稳定 ID，禁止使用数组下标。
+
+---
+
+## 7. 分步实施计划
+
+### FE-0：冻结参考视觉与行为基线
+
+任务：
+
+1. 在 1440×900、1280×800、1024×768 打开参考页面。
+2. 保存初始态、方案态、运行态和节点说明抽屉四组截图。
+3. 记录顶栏、两栏比例、间距、圆角、边框、阴影、画布工具栏和状态色。
+4. 形成“参考组件—目标组件—允许差异”表。
+5. 明确消息列表保持 DeerFlow 原样，不纳入像素对齐。
+
+交付物：
+
+- 视觉基线截图。
+- 视觉 token 表。
+- 页面行为清单。
+
+验收：参考的每个用户可见状态都有截图或明确说明不存在。
+
+### FE-1：路由、菜单和静态页面骨架
+
+任务：
+
+1. 增加两个路由和菜单项。
+2. 创建 `ReportCollaborationPage`。
+3. 创建顶栏、左侧对话栏、右侧画布和底部连接栏。
+4. 实现可调整宽度的两栏布局，以及“专注对话/专注画布”切换。
+5. 实现窄屏单面板切换与覆盖式节点 Drawer。
+
+验收：
+
+- 不连接后端也能呈现完整空态。
+- 375～1440px 不出现页面级横向滚动。
+- 对话/画布切换不会卸载会话状态或清空输入内容。
+- 键盘可以调整两栏分隔条。
+
+### FE-2：页面设计系统与 Coze 风格重建
+
+建立页面专用语义变量：
+
+```text
+--rc-bg-page
+--rc-bg-panel
+--rc-bg-canvas
+--rc-border
+--rc-text-primary
+--rc-text-secondary
+--rc-accent
+--rc-running
+--rc-waiting
+--rc-success
+--rc-danger
+--rc-panel-shadow
+--rc-card-radius
+```
+
+规则：
+
+- 从 DeerFlow 主题 token 派生，不在组件中散落十六进制颜色。
+- 使用 Lucide SVG 图标，不使用 emoji。
+- hover/focus/展开动画控制在 150～300ms。
+- 支持 `prefers-reduced-motion`。
+- 交互状态不能只靠颜色表达。
+- 正文对比度达到 4.5:1。
+- 操作超过 300ms 显示 spinner、骨架或流式状态。
+
+验收：除 MessageList 内部外，两栏布局、密度、卡片、画布工具栏、弹窗和节点抽屉达到参考基线。
+
+### FE-3：API 类型和 TanStack Query 层
+
+实现：
+
+- session CRUD。
+- messages 查询与发送。
+- plan request、plans 查询、select。
+- run 创建、查询、停止、重试。
+- command 创建、确认、取消。
+- artifacts、sources、reports、versions 查询。
+
+每个写请求携带：
+
+- `idempotencyKey`
+- `expectedRevision`
+
+冲突行为：
+
+- `409`：刷新当前快照并提示用户重新确认。
+- `422`：在对应操作附近显示具体错误。
+- `429`：显示预算/并发限制，不自动重试。
+- `5xx`：保留用户输入，允许使用同一幂等键重试。
+
+验收：API 层不包含页面展示逻辑，类型与后端 OpenAPI 一致。
+
+### FE-4：SSE、快照和事件 Reducer
+
+实现 `useReportCollaborationStream`：
+
+1. 先拉 session snapshot。
+2. 使用 snapshot 的 `lastSeq` 建立 SSE。
+3. 校验每个事件 session/run 身份。
+4. 按 seq 应用事件并去重。
+5. 出现序号缺口时暂停 live apply，补拉缺失事件。
+6. 断线指数退避并支持 `Last-Event-ID`。
+7. 终态后完成最后一次事件补拉再关闭连接。
+
+Reducer 必须覆盖：
+
+- 消息流增量。
+- 计划候选和 revision。
+- node/node attempt 状态。
+- artifact 创建和校验。
+- command 分类和执行。
+- report delta 和正式版本。
+- 错误、取消、接管恢复。
+- AgentScope 原始可见消息和工具事件：`message.created/delta/completed`、`tool_call.created/delta/completed`、`tool_result.created/delta/completed`、`team_message.created/delta/completed`。
+
+验收：重复事件、乱序事件和重连都不产生重复消息、重复节点或状态倒退。
+
+### FE-5：复用 DeerFlow `MessageList`
+
+复用：
+
+- `frontend-web/src/components/workspace/messages/message-list.tsx`
+- `frontend-web/src/components/workspace/messages/message-list-item.tsx`
+- `frontend-web/src/components/workspace/messages/message-group.tsx`
+- `frontend-web/src/components/workspace/messages/context.ts`
+
+实现无损协议适配 `message-adapter.ts`：
+
+1. 将已持久化的 `CollaborationMessage` 一对一映射为 LangGraph SDK `Message[]`，不将文本或工具结果二次概括。
+2. 构造最小 `BaseStream<AgentThreadState>` 外观：`messages`、`isLoading`、`isThreadLoading`、`values`。
+3. 协调者、成员 AgentScope TeamSay 和成员回复都映射为普通 assistant 消息；保留 `messageId`、文本 chunk、角色/成员名称、`agentRunId`、`nodeRunId`、`phaseId`、来源事件 ID 和完成态。
+4. AgentScope 工具调用映射为该 assistant 消息的标准 `tool_calls`；调用结果映射为标准 `tool` 消息，并严格复用原有 `tool_call_id` 配对。工具参数、返回正文及增量保持原文，只有后端明确标注的脱敏字段被替换。
+5. 将来源、文件、报告 Markdown delta 和正式版本继续映射为既有引用、文件卡和普通 assistant 消息；规划卡、用户确认卡和报告替换卡仍通过一个通用业务卡片插槽渲染。
+6. 错误、恢复建议、命令影响范围和报告版本变化也必须进入同一时间线；错误堆栈以可读错误消息替代，但不能吞掉已发生的工具/成员消息。
+7. `selectMessagesForAgentRun(allMessages, focusedAgentRunId)` 只在客户端从已同步消息中选出共享消息与目标成员消息；并行选择器不得重新拉取、重新排序或改写消息。
+
+约束：
+
+- 不使用 LangGraph `useThreadStream` 发送消息。
+- 新页面输入框调用报告协作 API。
+- 不增加多个页面专用 MessageList props。
+- 普通聊天、AI 写作、深度研究等未传插槽时必须零变化。
+- 不另建执行结果列表、节点结果面板或成果时间线。
+- 不用“运行中”“已检索 N 条”等专用摘要替代真实消息。`MessageList` 本身的流式状态和原生工具步骤是唯一过程视图。
+
+验收：
+
+- 历史和流式消息使用同一行稳定更新。
+- 单成员首次开始回复、每次工具启动和工具返回均在 300ms 内出现可见的原生消息行或原生工具步骤；不允许持续数秒只有静态加载圈。
+- 并行标签切换后显示目标成员的完整已持久化消息和实时 delta；未选中成员持续接收，标签上的运行/待回复状态及时更新。
+- 用户上翻阅读时不强制滚底。
+- 用户发送新消息后滚到最新位置。
+- 卡片显示成功不改变后端节点状态。
+
+### FE-6：需求澄清和候选方案卡片
+
+`ReportPlanCards` 展示：
+
+- 推荐标签、策略、标题、摘要和推荐理由。
+- 分析角度和参与角色。
+- 关键步骤与质量门。
+- 预计时间、成本等级和资料范围。
+- 方案验证错误。
+
+交互：
+
+- 点击卡片或“查看流程”只切换预览。
+- “采用此方案”调用 select API。
+- “开始协作”再次校验并创建 run。
+- 方案调整后显示新 revision；旧 revision 只读。
+- 过期 revision 返回 409 后不静默覆盖。
+
+验收：连续快速切换三张卡时，画布最终显示最后一次选择，不闪回旧图。
+
+### FE-7：协作流程画布
+
+技术：`@xyflow/react`。可以借鉴但不直接耦合：
+
+- `frontend-web/src/components/ai-elements/canvas.tsx`
+- `frontend-web/src/roundtable-planning/components/FlowGraphPanel.tsx`
+
+节点显示：
+
+- 节点名、角色名和分析角度。
+- 状态文字、图标和颜色。
+- 等待用户、返工、失败和 superseded 标记。
+
+画布能力：
+
+- 自动布局。
+- 拖动节点只保存浏览器展示位置。
+- 缩放、适配视图、方向切换、小地图。
+- 活动边低强度流动动画。
+- 点击节点打开覆盖在画布上的节点说明抽屉。
+- 节点重跑、补充或纠偏一律通过左侧对话完成；抽屉只提供“在对话中对此节点提出意见”入口。
+- 方案切换后清理不属于新方案的本地坐标。
+
+验收：
+
+- 30 个节点内流畅操作。
+- 单个 node event 不导致整个 React Flow 重挂。
+- `awaiting_input`、`reopened`、`superseded` 不与 `completed` 混淆。
+
+### FE-8：节点说明抽屉与对话定位
+
+点击画布节点打开 `NodeInspectorDrawer`。抽屉只展示计划合同：
+
+1. 节点名称、角色、分析角度和当前状态标签。
+2. 节点职责：负责解决什么问题。
+3. 要根据什么：所需输入类型、上游节点类型、资料范围和时效要求。
+4. 要产出什么：成果类型、结构要求和验收条件。
+5. 可用工具、禁止事项、预算上限。
+6. 上游与下游关系。
+
+抽屉不展示：
+
+- 节点实际生成内容。
+- 工具调用返回值。
+- EvidenceBundle 或其他成果物正文。
+- attempt 执行时间线。
+- 错误堆栈和调试信息。
+- 报告正文。
+
+交互：
+
+- “在对话中对此节点提出意见”关闭抽屉、聚焦左侧 Composer，并绑定 `targetNodeId` 上下文。
+- 若该节点对应正在并行运行的成员，同时绑定该成员的 `agentRunId` 并切换左侧选择器，使用户发送前能先看到该成员的真实对话与工具过程。
+- 用户仍需在对话区输入“重新检索”“重新分析”等要求；抽屉不直接发起业务变更。
+- 状态标签来自后端节点状态，但不加载节点结果接口。
+- 关闭抽屉不清空 selected node；再次点击同一节点可恢复说明。
+
+报告预览不使用常驻第三栏。最终报告、章节候选和版本先作为左侧 MessageList 中的普通消息/文件卡出现；点击文件卡时复用 `ArtifactFileDetail` 或现有 Markdown 能力打开大尺寸 Dialog，关闭后回到两栏工作台。
+
+验收：
+
+- 抽屉宽度不改变两栏布局，不挤压左侧对话区。
+- 抽屉只读取节点合同和图结构，不请求节点执行结果。
+- 所有原生成员消息、工具过程、错误和报告入口都能在左侧对话时间线找到。
+
+### FE-9：全过程对话干预
+
+`ReportComposer` 根据状态显示不同提示：
+
+- 空闲：输入报告需求。
+- 规划中：补充要求将在规划安全点应用。
+- 运行中：协调者正在判断影响范围。
+- 等待用户：优先回答等待问题。
+- 完成后：可问答、重写、润色或重新研究。
+
+发送流程：
+
+1. 生成 idempotency key。
+2. 插入 pending 用户消息；带 `targetNodeId`/`agentRunId` 时在相关成员消息流和共享上下文中引用同一条用户消息，不重复持久化。
+3. 显示“正在识别修改范围”。
+4. `command.classified` 后展示意图和影响节点。
+5. 高成本或低置信度命令显示确认卡。
+6. `command.accepted` 后显示排队或等待安全点。
+7. 完成后关联新 node attempt 或 report version。
+8. 失败时保留原消息和重试入口。
+
+典型映射：
+
+| 用户输入 | 预期操作 |
+|---|---|
+| “增加政策风险角度” | 新增角度节点和受影响下游 |
+| “资料太旧，重新找” | 重新检索指定证据包 |
+| “竞争格局分析不到位” | 复用证据，重新分析 |
+| “重写第二章” | 只生成章节替换候选 |
+| “语气更正式” | 新报告版本，不重新研究 |
+| “为什么得出这个结论” | 只读问答，不修改报告 |
+
+验收：
+
+- 双击发送不创建重复命令。
+- 选中“品牌竞争分析师”后发送补充要求，只影响该成员及依赖分析，其他并行成员仍保持消息流和运行状态。
+- 运行中反馈不会让 run 或 node 误变 completed。
+- “重写第二章”不会触发全量检索。
+- “资料太旧”不会只做文字润色。
+
+### FE-10：会话历史、报告版本与导出
+
+- History Tab 显示标题、状态、更新时间、当前版本。
+- 新建会话不删除旧会话。
+- 会话切换时先关闭旧 SSE，再加载新快照。
+- 报告修改先生成候选，确认后创建新版本。
+- 版本恢复创建新的头版本，不删除历史。
+- 下载复用现有 Markdown/Word 能力。
+- 文件名来自报告标题，不暴露宿主机或沙箱路径。
+
+验收：历史会话可完整恢复左侧消息流程、右侧节点状态和报告版本；不额外恢复节点结果面板。
+
+### FE-11：测试、视觉回归和性能
+
+单元测试：
+
+- event normalizer/reducer。
+- message adapter。
+- plan revision 和选择状态。
+- node status 和 available actions。
+- command pending/idempotency。
+
+组件测试：
+
+- 空态、澄清、规划、候选、运行、等待、完成、失败、取消。
+- 卡片选择、节点点击、只读说明 Drawer、确认弹窗和报告预览 Dialog。
+- MessageList 通用业务卡插槽零回归。
+- 单成员流式文本、TeamSay、工具调用与工具返回的原样重放；并行成员交错到达、切换标签、切回后不中断 delta。
+- 非当前标签成员发起协助时显示待回复徽标，点击后使用原生协助卡回复到正确节点。
+
+E2E：
+
+1. 新建会话并输入新能源汽车报告要求。
+2. 选择候选并开始。
+3. 运行中增加风险角度。
+4. 重新检索海外最新资料。
+5. 完成后重写第二章。
+6. 刷新、断网重连、切换会话。
+7. 停止和重试失败节点。
+
+性能门：
+
+- 30 节点画布不卡顿。
+- 长消息列表使用现有优化策略。
+- SSE 高频 delta 合帧后再 setState。
+- 画布和消息区使用独立 selector，避免互相触发整树重渲染。
+- 节点抽屉只订阅节点合同和状态，不能因阶段产出更新而反复重渲染。
+- 只渲染当前聚焦成员和共享消息的可视窗口；非当前成员的消息仍写入 store，但不因 token delta 重渲染当前 `MessageList`。

+
+## 8. 后端接口依赖
+
+前端开发前，后端必须冻结以下接口：
+
+```text
+POST   /api/report-collaboration/sessions
+GET    /api/report-collaboration/sessions
+GET    /api/report-collaboration/sessions/{session_id}
+PATCH  /api/report-collaboration/sessions/{session_id}
+DELETE /api/report-collaboration/sessions/{session_id}
+
+POST   /api/report-collaboration/sessions/{session_id}/messages
+GET    /api/report-collaboration/sessions/{session_id}/messages

+POST   /api/report-collaboration/sessions/{session_id}/report-rewrites
+POST   /api/report-collaboration/sessions/{session_id}/report-rewrites/{id}/apply
+```
+
+前后端共享枚举：
+
+- session status。
+- run status。
+- node/node attempt status。
+- command intent/status。
+- event type/version。
+- artifact type/schema version。
+- report version/change type。
+
+---
+
+## 9. 前端开发顺序
+
+1. `RC-FE-001`：视觉截图与行为基线。
+2. `RC-FE-002`：路由、菜单和左对话/右画布两栏空壳。
+3. `RC-FE-003`：页面 token、弹窗、抽屉和响应式。
+4. `RC-FE-004`：API 类型和 mock server。
+5. `RC-FE-005`：SSE reducer 与快照恢复。
+6. `RC-FE-006`：MessageList adapter 和通用卡片插槽。
+7. `RC-FE-007`：需求澄清与候选方案卡。
+8. `RC-FE-008`：流程画布和自定义节点。
+9. `RC-FE-009`：只读节点说明抽屉与对话目标定位。
+10. `RC-FE-010`：统一 Composer 和命令确认。
+11. `RC-FE-011`：报告预览、版本和导出。
+12. `RC-FE-012`：历史、重连和异常恢复。
+13. `RC-FE-013`：组件/E2E/视觉/性能验收。
+
+依赖规则：
+
+- `RC-FE-004` 必须等待前后端契约冻结。
+- 页面骨架和视觉可与后端 BE-0～BE-3 并行。
+- 真实 SSE 联调必须等待后端 durable event store。
+- 报告版本操作必须等待后端候选应用语义完成。
+
+---
+
+## 10. 前端完成定义
+
+前端只有同时满足以下条件才算完成：
+
+1. 页面结构与 Coze 参考页面逐状态验收通过。
+2. 消息区复用 DeerFlow `MessageList`，其他聊天页面无回归。
+3. 候选卡、左侧对话流程、右侧流程图和报告来自同一 session/run/event 状态。
+4. 点击候选只预览，明确确认后才执行。
+5. 用户可以在规划、运行、完成后三个阶段继续对话。
+6. 协助卡显示或提交不会导致前端误标完成。
+7. 节点点击只打开说明抽屉，可查看职责、所需输入、预期输出、工具和验收条件，不展示执行结果。
+8. 节点重开、返工和 superseded 状态表达正确。
+9. SSE 重连、刷新和历史切换无重复消息和状态倒退。
+10. 报告修改以候选和版本形式完成，不直接覆盖正式报告。
+11. 页面始终只有对话与画布两个常驻区域，所有执行过程和产出入口都能在对话时间线中找到。
+12. 响应式、键盘、对比度、加载反馈和错误恢复通过验收。

+### Workflow Studio stream and canvas compatibility

+- `app/gateway/workflow_agent_runner.py` is the boundary between LangGraph token chunks and durable workflow events. Provider reasoning in `AIMessage.additional_kwargs.reasoning_content`/`reasoning` is emitted to the UI as balanced inline `<think>` blocks; only visible answer content becomes the node's `text` output for downstream nodes. It must also emit every original `[AIMessage|ToolMessage, metadata]` tuple as `node.message.data.messages` with no whitelist, preview or length crop. Tool results and `additional_kwargs.clarification` are needed by the Studio's DeerFlow-compatible message UI and must survive durable SSE replay.
+- An agent `ask_clarification` ToolMessage pauses the workflow at that agent node (`awaiting_input`), not as a terminal run. The pause records the source `nodeRunId`/`toolCallId`; resuming turns the submitted reply into the next user message on the same `wf-{run}-{node}` LangGraph thread. Keep the raw ToolMessage authoritative; do not invent a second card payload.
+- `app/gateway/workflow_proposal_planner.py` converts the workflow controller's selected catalog roles into per-agent `mission`/`deliverable`/`scope`/`handoff` contracts. Only a selected visible `agentId` may contribute a contract; every omitted or malformed field falls back to a deterministic role-aware contract. Preserve this prompt-level worker boundary when adding strategies: researchers must not silently become final writers, and sequential roles must receive their upstream handoff binding plus an explicit next handoff.
+- `app/gateway/routers/workflows_coze_compat.py` must return both `creator.self: true` and editable VCS metadata for an owned standalone workflow. Coze Playground derives its preview/read-only mode from those fields, so omitting `creator.self` disables node dragging even when the standalone page passes `readonly={false}`.

Master switch + all limits: `config.yaml` → `workflows` (`deerflow.config.workflow_config.WorkflowConfig`). `workflows.agent_recursion_limit` defaults to 250: LangGraph counts each model→tool research exchange as about two super-steps, so workflow agent/skill nodes must not fall back to a chat-sized 60-step limit. In the local Studio proxy, keep Rsbuild `server.compress: false`; dev gzip buffers small SSE frames and makes live planning/run output arrive only at completion despite the backend's `no-transform` / `X-Accel-Buffering: no` headers. The composer’s optional `modelName` must be validated against `AppConfig.models`: it selects the controller model and is copied only into newly generated candidate agent configs (or the projected direct-agent task), never injected into an already-confirmed proposal/run.

 **Execution kernel is a custom DAG scheduler, not a compiled LangGraph.** LangGraph stays the kernel *inside* an `agent`/`skill` node. The reason is single-source-of-truth recovery: a re-leased or resumed run replays completed node outputs from `workflow_node_runs` plus the `workflow_run_events` log, so a second (checkpoint) copy of workflow-level state would have no defensible tie-breaker.

 - `runtime/engine.py` — the scheduler. Every edge is `pending` → `active` (source chose this port) or `pruned`; a node is ready when its non-back incoming edges are all resolved and at least one is `active`, and is skipped when all are `pruned` (skips propagate). That one rule covers fan-out, condition branching, and merge joins with no topological pre-pass. The `loop` node's `continue` back edge is the only permitted cycle; re-entry clears the body's results and invalidates its node runs.

+- Candidate workflow graphs remain editable after they are loaded into the Coze-compatible canvas; the compatibility response explicitly marks the current owner as editable so node dragging is not mistaken for a read-only preview.
+- Workflow-agent SSE forwards provider `reasoning_content` as an inline `<think>…</think>` trace for the UI while keeping the executable node output limited to the visible answer text. Every native LangGraph `[AIMessage|ToolMessage, metadata]` frame is additionally persisted and sent as `node.message.data.messages` without projection or length cropping, so the Studio can replay DeerFlow's tool-result, search-result and `ask_clarification` cards exactly after reconnecting.

+### Conversation-driven workflow planning
+
+The Workflow Studio chat composer does not silently start a template. A normal user
+message first creates a durable planning session with
+`POST /api/workflows/{workflow_id}/planning-sessions/stream` (SSE; the legacy
+non-streaming `POST /api/workflows/{workflow_id}/planning-sessions` remains for
+integrations). The stream relays safe DeerFlow controller milestones—catalog read,
+controller parsing, role selection, graph assembly and validation—before returning
+the final session, so the UI never has to fabricate a progress bar. The constrained planner builds
+two or three validated candidate graphs from the current draft and the visible business
+agents the user can use. It is a dedicated built-in **工作流总控** (`workflow-planner`),
+not the multi-agent roundtable coordinator: it only reads the user requirement and
+catalog metadata, selects permitted agent ids, and ranks the supported strategies. It
+does not dispatch a roundtable, use research tools, or execute a formal run. The server
+constructs the executable graph from those selected, visible resources; a controller
+failure returns an explicit planning error rather than a keyword/template fallback. The
+controller call has no callable tools and disables model thinking, so it adds one bounded
+planning inference without starting research or worker-agent costs. A
+browser selects one candidate, automatically applies the editor's DAG layout when
+it loads, then may explicitly save an edited graph through
+`PATCH /api/workflows/planning-sessions/{session_id}/proposals/{proposal_id}/graph`,
+then creates the one formal run through the existing
+`POST /api/workflows/{workflow_id}/runs` endpoint with `planningSessionId` and
+`proposalId`. The gateway rejects unselected or invalid candidates and makes a repeated
+confirmation return the already-created run, so a double click cannot execute a second
+workflow. Planning sessions are persisted separately from runs (migration
+`20260831_01`); their parent row is flushed before candidate rows so the foreign-key
+transaction works consistently across SQLite, MySQL, and PostgreSQL. A candidate is
+not consuming execution resources until it is confirmed.
+
+The development Studio proxy must not gzip `/api` responses: compressed SSE can hold
+small planning and run-event frames until the response ends. The backend already marks
+both streams `no-transform` and `X-Accel-Buffering: no`; `apps/coze-studio` also sets
+its Rsbuild development server `compress: false`. Agent/skill nodes use the bounded
+`workflows.agent_recursion_limit` (default `250`), rather than a chat-sized 60-step
+limit, because a model-to-tool research turn consumes about two LangGraph super-steps.
+The composer may also send a configured `modelName`: the server validates it against
+the safe model catalog, uses it for the workflow controller, and writes it into the
+generated candidate agent nodes. For a direct single-agent task it overrides only that
+projected node; confirmation still executes the immutable selected proposal snapshot.
+The controller additionally creates a per-selected-agent task contract (`mission`,
+`deliverable`, `scope`, `handoff`). The graph builder accepts contracts only for
+catalog-visible, selected agent ids and injects each one into that worker's prompt, so
+parallel branches receive complementary research assignments and sequential branches
+have an explicit review/handoff boundary rather than all workers attempting the whole
+user task. Missing controller fields receive a deterministic role-aware contract.
+When an agent emits DeerFlow's native `ask_clarification` ToolMessage, the workflow
+enters `awaiting_input` rather than completing or failing. The pause event references
+the originating `nodeRunId` and `toolCallId`; the browser renders that original card
+inside the agent message and `POST /runs/{run_id}/resume` supplies the user's reply as
+the next turn of the same agent thread.
+
+The current planner is deliberately constrained: it can rank supported strategies and
+focus resources, but the server builds the graph from the already configured agent
+nodes. It cannot invent a node type, external target, or credential from chat text.
+For a parallel-research candidate, the configured research agents first flow into the
+deterministic `evidence_normalizer` node. It emits a bounded Evidence Pack with the
+originating node, role label, explicit gaps, and no invented verification claim before
+the synthesis agent sees it. The candidate then runs `deep_research_write`: its
+app-layer adapter converts exactly that Evidence Pack into selected, provenance-tagged
+Deep Research source rows, starts or reattaches to the existing durable Deep Research
+job, forwards report deltas as workflow `node.output.delta` events, and exposes the
+final Markdown as a run artifact. Cancellation is forwarded to the same research job;
+the node never calls the Deep Research HTTP API or launches a second writer. The
+session key includes the topic, evidence snapshot and writing configuration, so a retry
+reuses the same job while a changed upstream pack cannot return stale report prose. `multi_agent` Deep Research is
+intentionally not nested yet because its separate plan-review pause would conflict
+with workflow `human_input`. A completed `agent` or `skill` node in a terminal,
+acyclic run can now receive targeted feedback through
+`POST /api/workflows/runs/{run_id}/feedback`: the original remains immutable, a
+revision run reuses completed nodes outside the target's downstream closure, and
+only the target prompt receives the bounded feedback block before it and its
+downstream nodes stream again. The public revision run retains the affected and
+reused node ids in its feedback summary for the conversation/history UI. Running and looped workflows deliberately continue
+to use `human_input` or a new full run; they are not modified in place. See
+`docs/WORKFLOW_CONVERSATIONAL_MULTI_AGENT_ORCHESTRATION_ZH.md` for the roadmap.

+# 页面研报设计师
+
+你是「页面研报设计师」：把用户提供的数据、附件、当前会话产物和已生成的 Markdown 报告，组织成可交付的 HTML 汇报页面。你擅长深蓝和浅色大屏、文字型研判面板、表格、卡片、图表、甘特图与克制的动效。
+
+你只编辑当前会话的工作副本和 `outputs/` 产物，绝不修改模板源文件。
+
+## 先判断要不要画页面
+
+1. 用户只是提问、解释、讨论、审阅时，正常用文字回答，不生成页面。
+2. 用户明确要求 Markdown / 报告 / 方案文档，且没有要求页面或 HTML 时，正常产出 Markdown；不要强制画页面。
+3. 用户明确说“页面、HTML、大屏、看板、可视化、图表展示、把材料做成页面”时，生成页面。
+4. 对于有明确“创作/产出”意图但未指定格式的请求，默认生成页面；若语气更像普通问答，仍按问答处理。
+
+## 材料与检索边界
+
+- 先读取本轮用户材料、上传文件、会话中的 Markdown / JSON 产物；已有信息足够时直接制作，**不得自动检索**。
+- 信息不足以支撑结论、用户没有提供数据且未授权检索时，先简洁说明缺口，并询问：“是否允许我检索公开资料补充？”不要先调用 `web_search`。
+- 用户明确强调“即使没有数据也要图表”时，仍应正常绘制图表：使用用户已给的定性信息或合理示意数据，但必须在图例、口径或脚注标注“示意数据 / 待补充数据”。不得把示意数值说成真实事实。
+- 用户确认可以检索后，才使用 `web_search`；把来源、日期和不确定性写进相应文字面板或页脚。
+
+## 页面生成流程
+
+1. 将材料归为：事实数据、可推导结论、待补充项、图表数据、长文本、表格行、行动/风险项。优先保留用户原文的关键判断和数据口径。
+2. 读取 `page-template-library` 技能；调用 `page_report_template(action="prepare")`，传入当前界面提供的 `presentation_theme`（`dark` 或 `light`）。无该上下文时，按用户明示主题，否则默认浅色。
+3. 页面文字通常要多于图表：至少包含结论摘要、关键发现、事项/风险说明、数据口径或来源、行动建议中的多个展示样式。材料丰富时优先生成约 3 页；材料较少时删减模板页和无数据卡片，不留空面板。
+4. 复制后的工作副本是骨架。保留已有图表渲染、动效和导航逻辑；用真实数据替换 `reportData` 和相关文本。若模板存在 5 页，可保留其中最贴合的 3 页而不是机械展示全部。
+5. 所有可见正文、表头、标签、说明文字最小字号均为 16px；长文本面板要增高、提高行高，不能把段落挤成一团。
+6. 最终 HTML 写入 `/mnt/user-data/outputs/`。调用 `page_report_template(action="validate")`；若返回错误，先修复再交付。通过后调用 `present_files` 展示 HTML 和必要的质量报告。
+
+## 设计要求
+
+- 跟随 `presentation_theme`：`dark` 选深蓝骨架，`light` 选浅色骨架；不要把产品现有聊天页面风格照搬进汇报页面。
+- 深色使用深蓝科技感，选中状态可有细腻的扫描光、描边或流光；浅色使用清晰留白与高对比文字。
+- 动效服务于阅读：数字滚动、图表入场、进度条、轻量背景粒子即可；支持 `prefers-reduced-motion`，不使用刺眼或持续大幅运动。
+- 图表必须与材料一致。数据不够时宁可删掉图表或明确标为示意，不伪造事实；避免为了“丰富”而堆满图。
+- 文字展示不能只是一种卡片。灵活组合：摘要带、洞察卡、左右对照、时间线、风险清单、引用/口径块、行动闭环、说明段、表格、问答式要点、负责人/截止日清单。
+- 每页都要有明确标题、数据时间/口径、可读的结论。HTML 必须自包含，不依赖第三方 CDN。

+# 对话驱动的多智能体工作流编排：开发设计说明
+
+> 状态：阶段 A、Evidence Pack、Deep Research 写作接入和阶段 C 的首个“终态节点定点修订”闭环已实现；其余阶段仍为设计与待开发项（以 2026-08-31 的代码为基线）  
+> 适用范围：工作流编辑器的“对话运行”页面、工作流运行时、深度研究报告能力  
+> 关联文档：[WORKFLOW_STUDIO_BACKEND_DEV_ZH.md](./WORKFLOW_STUDIO_BACKEND_DEV_ZH.md)、[ADR 0001](./adr/0001-workflow-studio-runtime.md)
+
+## 1. 要解决的问题
+
+用户在工作流页面输入一个自然语言任务后，系统应能理解意图、选择合适的工作流模板和智能体角色、并行收集信息、多角度分析、汇总证据，最后生成可追溯的高质量报告。整个过程不是“等所有模型返回后一次性展示”，而是可实时观察、可插话、可调整、可停止和可局部重跑的执行过程。
+
+典型任务例如：
+
+> “分析本周销售下滑的原因，结合用户反馈和竞品投放，给出下周广告与产品体验改进建议，并整理成汇报报告。”
+
+该任务应该被拆成可执行的子任务，而不是把原句依次发给多个 Agent：
+
+```text
+用户消息
+  │
+  ▼
+意图理解 / 计划生成
+  │       ├── 信息不足 ──► 用户协助卡片 ──► 同一运行恢复
+  ▼
+工作流模板与角色选择
+  │
+  ├── 销售/业务数据收集 ─┐
+  ├── 用户反馈收集      ├──► 证据归一化与校验 ─► 多视角分析

+                                                       ▼
+                                             质检、引用、产物输出
+```
+
+## 2. 设计结论
+
+采用“**薄总控智能体 + 候选流程选择/编辑 + 确定性工作流运行时 + 专项智能体/技能 + 专用报告写作管线**”的结构。
+
+- 总控（Planner/Controller）只做语言理解、任务规划、候选流程/角色选择、缺失信息判断和变更影响评估。
+- 总控一次给出 2–3 条可执行的候选流程；用户选择其中一条后，在右侧画布检查和修改，再显式确认执行。模板只是候选图的后端积木，不是系统静默替用户作出的最终选择。
+- 工作流引擎仍是唯一的调度者：负责 DAG 依赖、并发、重试、暂停、恢复、取消、权限、事件持久化和状态归并。
+- 专项 Agent 按明确角色执行收集、分析、审校等任务；它们不拥有全局调度权。
+- Deep Research 写作能力作为一个可运行、可流式输出的专用节点接入，不把它的内部流程混进总控 Prompt。
+
+因此，“总控智能体”不是一个包办所有事情的 God Agent。它产生受约束的计划；能否执行、执行什么副作用、如何重试，必须由可审计的后端运行时决定。
+
+## 3. 当前代码基线：已有能力与缺口
+
+下表区分当前已有实现和本文建议新增的能力，避免把设计目标误认为已经实现。
+
+| 范围 | 当前已有实现 | 仍需补齐 |
+| --- | --- | --- |
+| 工作流调度 | 自建持久化 DAG 运行时，支持依赖、并发、条件、循环、暂停/恢复、取消与事件日志。核心位于 `packages/harness/deerflow/workflows/runtime/engine.py`、`app/gateway/workflow_executor.py`。 | 计划版本、局部失效/重算、由计划驱动的模板实例化。 |
+| Agent 节点 | `workflow_agent_runner.py` 中的 Agent/Agent Skill 使用 `make_lead_agent`，并从 `agent.astream()` 转发文本增量与工具事件。 | 完整 Role Catalog、结构化计划校验、上下文与产物的统一输入输出契约。 |
+| Evidence Pack | `evidence_normalizer` 已是确定性节点：把并行研究节点的结果归一化为有来源节点、角色标签、缺口和截断标志的 `evidencePack`；不会将 Agent 文本伪装成已验证事实。并行调研候选图自动在汇总 Agent 前插入该节点。 | 证据去重、外部来源质量评分、事实校验、引用格式化。 |
+| 流式事件 | 运行事件可持久化并通过 SSE 推送；现有事件覆盖 run、node、output、tool、artifact、awaiting input 等；`deep_research_write` 会把安全的报告增量投影为 `node.output.delta`。 | 计划事件、变更/版本事件、跨工作节点的统一报告回放/去重指标。 |
+| 对话运行 | 普通发送先创建持久化 `WorkflowPlanningSession`，后端从当前草稿和已授权 Agent 节点构建 2–3 个候选图；指定 Agent 时仍会投影为 `start → agent → output` 的独立任务。用户选择候选卡片、在画布编辑并确认后，才创建正式 run。终态、无循环 run 的已完成 Agent/Skill 支持定点反馈：创建不可变 revision，复用不受影响的完成节点，目标和下游重新流式执行。运行中输入新方向时，前端会先停止旧 run，保留审计，并将原任务与调整交给 Planner 生成新候选图。 | 真正的连续会话上下文、运行中节点的交互式局部调整、循环图/其他节点类型的影响分析、版本对比界面。 |
+| 规划持久化 | `workflow_planning_sessions` / `workflow_planning_proposals`（migration `20260831_01`）分离保存 query、候选图、推荐理由、图 revision、选择和确认结果；重复确认返回同一 run。 | 规划会话的过期清理、候选方案差异视图、复杂任务的多轮补充信息。 |
+| 人机协作 | `human_input` 节点会持久化等待状态，并以一次性 `resumeToken` 通过同一 run 恢复；前端已按 `formSchema` 渲染协助卡片、结构化字段和自然语言补充。 | 恢复后按输入影响范围使下游局部失效、复杂多轮协助与卡片审计视图。 |
+| 深度研究 | `deep_research_write` 已经复用独立 Deep Research 的 session/job/event/source 持久化：Evidence Pack 转成选中且可追溯的素材，报告正文投影为工作流增量，完成后创建 Markdown artifact；取消也传给同一作业。前端可将完整 Markdown 调用既有 Word 导出接口下载，不改写原 artifact。 | 证据去重/质量评分、引用格式化、把 Deep Research 的多智能体计划暂停映射为工作流 `human_input`。 |
+| 前端可观测性 | 对话区、运行事件、节点状态已有基础；当前前端已开始将运行状态映射为节点高亮和连线动效。 | 计划摘要、待确认项、用户协助卡片、版本/重跑记录、产物引用的产品化界面。 |
+
+说明：目前每个 Agent 节点默认使用独立线程 `wf-{run_id}-{node_id}`；只有显式 `threadMode: shared_run_thread` 才会共享 `wf-{run_id}`。这适合节点级隔离，但不能自动等价为“整个页面是一段持续对话”。

+
+### 4.1 职责边界
+
+| 组件 | 负责 | 不负责 |
+| --- | --- | --- |
+| Planner/Controller Agent | 理解用户意图；输出受校验的计划；选择模板和角色；识别缺失输入；解释变更影响。 | 直接调度节点、绕过权限调用工具、任意构造可执行图。 |
+| 工作流运行时 | 根据图和快照调度；管理状态、并发、失败、暂停、恢复、取消、事件、审计。 | 猜测业务意图、生成报告正文。 |
+| 研究/分析 Agent | 在给定任务、输入和允许能力内收集或分析，输出结构化结果和引用。 | 修改全局计划或直接驱动其他节点。 |
+| 技能/工具节点 | 执行受控的 API、SQL、检索或计算，并返回可验证结果。 | 接收未经授权的模型任意参数。 |
+| Human Assist | 向用户收集缺失/确认信息，恢复同一 run。 | 新建无关联运行来“续聊”。 |
+| Report Writer | 根据 Report Spec 与 Evidence Pack 输出报告、引用和文件产物。 | 代替 Planner 选择业务流程。 |
+
+## 5. 端到端运行流程
+
+### 5.1 首次发送
+
+1. 用户在左侧对话框提交消息，前端创建 `planning session`，输入包含 `query`、附件/资源引用、可选上下文和当前工作流版本。
+2. Planner 产生 2–3 个结构化 `WorkflowProposal`（每项含目标、角色、候选图、预估成本、缺失信息），而非只生成一段文字或静默启动一个模板。
+3. 后端校验每个候选图是否只引用已发布的节点、角色、技能和数据源；不合法的候选图不能展示为“可执行”。
+4. 前端在对话区展示候选流程选择卡片。用户点击卡片后，右侧画布加载该候选图；用户可拖拽节点、修改绑定、增删合法连接，再触发实时校验。
+5. 用户点击“确认此流程并执行”后，后端冻结编辑后的 graph snapshot，创建正式 `workflow run`。这一步之后才开始收集、处理、分析、汇总和报告节点；可并行的节点并行执行。
+6. 若确认前或运行中仍缺失关键条件，创建 `Human Assist` 暂停点，发送 `run.awaiting_input`；前端显示可填写的协助卡片。
+7. 每一个状态变化和文本增量都写入事件流；前端即时更新对话消息、节点状态和画布连线。报告节点完成后发布正文、引用、文件/链接等 artifact。
+
+### 5.2 用户在运行中插话
+
+用户消息必须区分为三种语义，不能全部当作“重新跑一遍”：
+
+| 用户动作 | 例子 | 后端处理 |
+| --- | --- | --- |
+| 补充输入 | “预算是 30 万，周期改成 4 周。” | 写入对应 Human Assist 或运行输入；使依赖该字段的节点继续/失效。 |
+| 定点反馈 | “竞品分析不要只看价格，补充渠道策略。” | 绑定到目标节点或输出 artifact，创建 `ChangeRequest`；仅重跑受影响的分析、合并、报告链路。 |
+| 改变任务 | “不要做广告方案了，改成用户留存诊断。” | Planner 评估影响；通常创建新的计划版本，必要时重新选择模板。 |
+
+推荐产品动作是：消息气泡附带“发送给谁”的可选入口，默认交给 Planner 判断；在某个节点/输出旁点击“让该智能体调整”时，前端携带明确的 `targetNodeId` 或 `targetArtifactId`。没有指定目标的消息不应默认广播给所有 Agent。
+
+### 5.3 用户协助卡片
+
+Human Assist 卡片必须代表持久化的等待状态，而不是普通聊天文本。它至少包含：
+
+- `runId`、`nodeRunId`、`requestId`；
+- 展示给用户的问题、字段定义、选项、校验规则、是否敏感；
+- 该输入会影响哪些下游节点；
+- 提交、稍后处理、取消运行三个动作。
+
+点击提交时调用“恢复同一运行”的接口，带 `requestId` 与结构化答案。运行时写入 input binding，事件从 `awaiting_input` 变为 `node.resumed` / `node.running`，之后按已有 DAG 继续。绝不能用“新建一条普通聊天消息”替代恢复；那会丢失图快照、依赖、审计和已完成结果。
+
+### 5.4 停止、重试和局部重跑
+
+- **停止**：取消 token 传到当前 Agent、工具和深度研究任务；run 标记为 `cancelled`，已完成 artifact 仍保留。
+- **失败重试**：只在输入和上下文未变时重试原 node run，保留 `retryOf` 关系。
+- **定点修改后重跑**：现有首个实现为 `POST /api/workflows/runs/{run_id}/feedback`，仅接受终态、无循环图中已完成的 `agent`/`skill` 节点。它从原 run 的冻结执行图计算下游闭包，创建带 `revisionOfRunId`/`feedback` 的新 run，复制闭包外已完成 node run；`feedback` 同时保留 affected/reused node ids 供历史和对话说明复用范围。反馈只加入目标节点的 `RunContext.env.nodeFeedback`，目标及下游重新流式执行，旧 run 不被覆盖。未传 `idempotencyKey` 时服务端按原 run、节点与文本生成稳定键。运行中流程应使用 `human_input` 或先停止；循环图、Deep Research/普通数据节点和副作用节点的定点改写仍需单独策略。
+- **重新规划**：只允许 Planner 生成新的、经过校验的计划版本；用户可在 UI 看到“旧计划/新计划”差异。对于已经发出模型请求的运行中节点，前端不得声称把新文本插入了旧 prompt；首期采用“停止旧运行（保留审计）→ 原任务 + 新调整交给 Planner → 用户确认新版候选图”的安全语义。常规缺失字段仍优先走同一运行的 `human_input`。
+
+## 6. 关键数据契约（建议新增）
+
+下面的对象是建议新增的业务协议，不表示当前接口已经提供。
+
+### 6.1 TaskPlan：总控输出
+
+```json
+{
+  "schemaVersion": "1.0",
+  "intent": "market_growth_diagnosis",
+  "summary": "诊断销售下滑并给出广告与体验改进建议",
+  "templateId": "growth-diagnosis-v1",
+  "requiredInputs": [

+    "citationRequired": true
+  },
+  "confidence": 0.86,
+  "needsHumanInput": false
+}
+```
+
+Planner 输出必须通过 JSON Schema / Pydantic 校验，并检查 `templateId`、`roles`、`allowedCapabilities` 是否都在租户已发布白名单中。不得以自然语言里的“调用某数据库/删除某文件”为依据直接执行。
+
+### 6.2 Evidence Pack：跨 Agent 的事实输入
+
+所有研究 Agent 的输出先归一化为证据包，再给分析和报告节点使用。这样能减少“前一节点随手写一段话、下一节点盲目采信”的问题。

+  "requestedBy": "user"
+}
+```
+
+服务端返回影响范围（例如 `competitor_analysis → evidence_merge → report_writer`）和建议动作。涉及范围较大或成本较高时，先要求用户确认再执行。
+
+### 6.4 Report Spec：报告写作输入
+
+报告写作节点的输入固定为 `ReportSpec + EvidencePack + 已确认的用户约束`。不要把整个聊天历史无筛选地塞进写作模型。
+
+`ReportSpec` 至少包含受众、语言、篇幅、结构、格式、引用要求、语气、禁止项、产物格式（Markdown / DOCX / PDF）和质量标准。
+
+## 7. 图模型与模板策略
+
+### 7.1 第一阶段：候选流程优先，模板作为积木
+
+Planner 从已发布的模板、节点角色和连接规则中组装 2–3 条候选流程，例如：
+
+- `quick-answer-v1`：少量检索 + 单 Agent 答复；
+- `growth-diagnosis-v1`：销售、VOC、竞品并行收集 → 策略分析 → 报告；
+- `market-research-v1`：多源研究 → 证据去重/校验 → 多视角分析 → 报告；
+- `deep-research-report-v1`：明确主题的研究与深度报告产出。
+
+每张卡片至少展示：推荐理由、关键步骤、参与角色、数据源/技能、预计耗时与成本、尚缺输入、风险提示。默认给出“推荐方案”，但不自动启动；简单任务也至少显示一张可确认的轻量方案。
+
+用户点击卡片后，候选图变成当前画布草稿。用户可以在受限的节点目录内修改节点、输入绑定和连接关系；每次修改调用现有图校验。确认时保存最终快照，再进入正式运行。这样既有智能规划，又不把图的控制权藏在模型内部。
+
+候选方案在确认前不是 `workflow run`，建议使用独立、短生命周期但可恢复的 `WorkflowPlanningSession` / `WorkflowProposal` 持久化模型；不能在一个已启动的 run 中途直接替换整个 graph。Planner 的职责是产出受约束的候选图，而不是生成任意拓扑。
+
+### 7.2 后续阶段：受约束的动态子图
+
+确实需要按任务动态增加并行研究视角时，可让 Planner 产出受限的 `PlanSpec`，由服务端编译为子图。要求：
+
+- 节点类型、角色、技能、连接规则来自白名单；
+- 设置最大节点数、最大并行数、最大预算和超时；
+- 编译后做 DAG/端口/类型/权限校验；
+- 保存最终 graph snapshot 与 plan revision，保证重放和审计；
+- 动态生成的是“已验证子图”，不是 Agent 直接操作数据库或调度器。
+
+## 8. 运行状态与流式协议
+
+### 8.1 状态模型
+
+现有运行状态可继续作为基础：`queued`、`running`、`awaiting_input`、`completed`、`failed`、`cancelled`。节点状态要至少支持 `queued`、`running`、`completed`、`failed`、`awaiting_input`、`cancelled`。
+
+建议为 revision 增加展示级状态：`stale`（旧版本保留但不再作为最新结果）、`invalidated`（输入变化导致必须重跑）、`reused`（在新版本中复用旧结果）。如需持久化，须在 schema migration 与 API 中显式加入，不能只在前端猜测。
+
+### 8.2 SSE 事件约定
+
+现有事件链路应继续作为单一事实来源：运行和节点事件先持久化，再由 SSE 推送。前端断线后按最后事件序号恢复，不依赖内存中的临时 token。
+
+建议在既有 `run.*`、`node.*`、`node.output.delta`、`artifact.*`、`run.awaiting_input` 之上增加：
+
+| 建议事件 | 含义 | 前端行为 |
+| --- | --- | --- |
+| `plan.ready` | Planner 产生并校验了 TaskPlan | 显示计划摘要、角色、待补充信息。 |
+| `plan.rejected` | 计划违反模板/能力/权限约束 | 展示可理解的原因，提示重新输入或人工选择。 |
+| `run.revision.created` | 用户变更创建了新版本 | 切换到新版本，保留旧版本可查看。 |
+| `node.invalidated` | 节点结果因变更失效 | 画布标记待重算，显示影响来源。 |
+| `node.reused` | 新版本复用了节点产物 | 展示复用，不播放“正在执行”的假动画。 |
+| `report.delta` | 写作服务持续输出报告正文 | 追加到报告消息，同时保留 node output 增量。 |
+
+事件最小公共字段建议为：`eventId`、`seq`、`runId`、`revision`、`nodeRunId?`、`type`、`timestamp`、`payload`。`seq` 必须在一个 run/revision 范围内单调递增。
+
+### 8.3 前端实时表现
+
+- `node.running`：节点高亮、对应入边/出边显示流动效果，左侧展示该节点的增量消息；
+- `node.output.delta`：立即写入该节点对应的 assistant 消息，使用节流批量渲染，不能等 `node.completed`；
+- `run.awaiting_input`：停止错误的“加载中”图标，显示协助卡片；
+- 并行节点：同时高亮多个节点，右侧执行摘要展示完成数量；
+- `completed/failed/cancelled`：停止动效并给出明确终态，不让旋转图标停在页面上。
+
+画布可以被用户关闭以让对话区扩大，但不得卸载运行订阅或丢弃节点状态；重新打开时应从事件状态恢复。
+
+## 9. 后端改造建议
+
+### 9.1 新增节点类型与适配器
+
+| 节点类型 | 输入 | 输出 | 实现建议 |
+| --- | --- | --- | --- |
+| `task_planner` | `query`、上下文、可用模板目录 | `TaskPlan` 或 Human Assist 请求 | 在 Agent Runner 之上增加严格结构化输出与服务端白名单校验。 |
+| `evidence_normalizer` | 多个研究结果 | `EvidencePack` | **已实现**：确定性转换、上游引用校验和长度上限；必要时后续增加独立事实校验节点。 |
+| `analysis_agent` | `TaskPlan`、Evidence Pack、角色提示 | 结构化分析与引用 | 继续复用 Lead Agent，但限制输入、技能和线程。 |
+| `human_assist` | 字段/问题/校验规则 | 已确认的结构化答案 | 复用现有 pause/resume，补全 requestId、表单 schema 与输入绑定。 |
+| `deep_research_write` | Report Spec、Evidence Pack、上下文 | 流式正文、引用、artifact | **已实现**：不经 HTTP 自调用，Evidence Pack 固化成选中素材后复用 `regenerate` Job；实时 `report_delta` 与持久 `report_chunk` 去重投影为 `node.output.delta`，取消转发给同一 Job。暂不嵌套 Deep Research `multi_agent` 的计划暂停。 |
+| `report_qa` | 草稿、引用、质量规则 | 通过/问题列表/修订建议 | 先用确定性规则，必要时再加审校 Agent。 |
+
+`callable_skill` 当前仍会返回“未可执行”的显式错误。若要用于这套流程，必须先建立技能注册表、输入 schema、权限校验、超时/取消、结果 schema 和审计；不能仅在 Planner 文本中列出技能名称。
+
+### 9.2 已落地接口与后续接口
+
+当前已实现的候选规划接口如下。候选图仅能使用当前草稿中可用的 Agent 节点及固定的安全拓扑；服务端校验图和资源目录，并以 `graphRevision` 防止两个页面互相覆盖编辑。`POST .../runs` 是唯一创建正式执行的动作；未选择、校验失败或已绑定到其他 run 的候选都会被拒绝。
+
+```text
+POST /api/workflows/{workflow_id}/runs
+  对已选择的 graph snapshot 创建正式运行；body 传 planningSessionId + proposalId。
+
+POST /api/workflows/{workflow_id}/planning-sessions
+  根据用户 query 生成候选 WorkflowProposal；返回会话、候选图和推荐原因。
+
+GET /api/workflows/planning-sessions/{session_id}
+  读取可恢复的候选规划会话与选择/确认状态。
+
+POST /api/workflows/planning-sessions/{session_id}/proposals/{proposal_id}/select
+  选择一条候选图，供右侧画布预览和编辑。
+
+PATCH /api/workflows/planning-sessions/{session_id}/proposals/{proposal_id}/graph
+  保存用户在画布中编辑后的候选图；后端执行拓扑、端口、类型和资源校验。
+
+```
+
+以下接口仍是后续阶段，尚未把建议对象落地为公开 API：
+
+```text
+
+GET  /api/workflow-runs/{run_id}/events?after_seq={seq}
+  SSE；支持断线续传与快照同步。
+
+GET  /api/workflow-runs/{run_id}/plan
+  获取当前 TaskPlan、revision 和待补充项。
+
+POST /api/workflow-runs/{run_id}/human-requests/{request_id}/responses
+  提交用户协助卡片答案并恢复同一 run。
+
+POST /api/workflow-runs/{run_id}/change-requests
+  创建定点反馈、补充输入或重新规划请求；返回影响范围和确认要求。
+
+POST /api/workflow-runs/{run_id}/revisions/{revision}/apply
+  在需要确认时应用已计算的变更计划。
+
+POST /api/workflow-runs/{run_id}/node-runs/{node_run_id}/retry
+  对原输入的失败节点重试；与“变更后的局部重跑”区分。
+```
+
+已落地的定点反馈接口使用现有运行命名空间，而不是上面的未来 `ChangeRequest` 协议：
+
+```text
+POST /api/workflows/runs/{run_id}/feedback
+  body: { nodeId, message, idempotencyKey? }
+  201: 新 revision run（revisionOfRunId、affectedNodeIds、reusedNodeIds）
+```
+
+所有写接口都应携带租户/空间、操作人、幂等键与权限上下文。对于存在副作用的技能（写库、发送消息、外部发布），需要独立确认策略，不能因为用户说“继续”就自动执行。
+
+### 9.3 计划版本与局部重跑
+
+长期建议新增逻辑对象：`WorkflowRunRevision`、`ChangeRequest`、`HumanRequest`。当前首个实现尚未新增表：revision 直接是一个普通 `workflow_runs` 行，`context.revisionOfRunId`、`context.feedback` 和 `retry_of_run_id` 指向源运行。一次用户修改的完整目标处理为：
+
+```text
+ChangeRequest
+  → Planner 评估影响（或规则引擎根据输入绑定计算）
+  → 生成 proposed revision + affected nodes
+  → 必要时要求确认
+  → 固化 revision、复制/复用可用产物
+  → 使受影响节点及其下游失效
+  → 从最早失效节点继续调度
+```
+
+不要就地覆盖旧 node run 的输入或输出。旧 revision 仍需可查看，才能解释“为什么报告改了”、支持回滚并满足审计。
+
+## 10. 前端交互规格
+
+### 10.1 页面布局
+
+- 左侧为默认主工作区：持续对话、候选流程选择卡片、运行消息、协助卡片和报告预览；宽度可拖动，用户关闭画布后自动扩展。
+- 右侧为可关闭的流程图：展示当前 graph snapshot 和执行状态；默认不抢占对话阅读空间。
+- 执行详情为辅助信息，不能替代对话中的实时反馈。
+- 输入框内使用图标发送按钮；发送中/等待人工输入/取消中有清晰且无歧义的状态。
+
+### 10.2 消息显示模型
+
+消息不要只以 `user/assistant` 两类存储。建议前端 ViewModel 支持：
+
+- `user_message`：原始任务、补充、定点反馈；
+- `planner_message`：已理解的目标、选用模板、计划摘要；
+- `agent_stream`：某一节点的流式过程和最终摘要；
+- `human_request`：可提交的协助卡片；
+- `system_event`：开始、停止、失败、重跑、复用等可读状态；
+- `artifact`：报告预览、下载文件、引用和版本信息。
+
+每个消息应带 `runId`、`revision`、`nodeRunId?` 和 `eventSeq`，SSE 重连时以这些键去重、补齐并排序。
+
+### 10.3 对话动作规则
+
+- 默认“发送”创建任务或把补充内容交给 Planner。
+- Planner 返回候选流程卡片而非直接执行；点击卡片加载右侧候选图，只有点击“确认并执行”才创建 run。
+- 候选图编辑期间可以切换到另一张卡片或重新让 Planner 生成方案；未确认的方案不会消耗执行型技能预算。
+- “发送给某智能体”是显式定点动作，显示目标名称和影响范围。
+- 点击 Human Assist 卡片只恢复原 run；禁止额外创建 run。
+- 点击节点可筛选该节点在左侧产生的消息、工具调用和产物。
+- 在报告中选择一段文字并要求修改时，生成指向该 artifact/section 的 `ChangeRequest`。
+- 终态后的新问题默认新建 run；“基于这次结果继续”则显式带 `parentRunId` 与所选 artifact，不能靠隐藏共享线程推断。
+
+## 11. 深度研究报告接入
+
+Deep Research 是长时任务，应该保持其现有作业模型。工作流节点只做以下适配：
+
+1. 提交 Job：将 `ReportSpec`、`EvidencePack`、可公开检索范围和已确认上下文提交给 Deep Research 服务；
+2. 订阅 Job：把研究进度、正文增量、引用和文件状态映射成 run/node 事件；
+3. 取消 Job：run 被停止或 revision 失效时向下传递取消；
+4. 固化产物：报告正文、引用清单和生成文件写入 artifact 存储，供后续 QA、用户修改和下载复用；
+5. 质量门：未达到引用/结构/敏感信息规则时，不直接标记为最终成品。
+
+传给写作管线的重点是已筛选的证据与明确的报告要求，不是多个 Agent 的原始长对话拼接。这样才可控制上下文长度、降低幻觉、保留来源归因。
+
+## 12. 实施顺序
+
+### 阶段 A：先打通当前消息与运行链路（部分完成）
+
+1. **已完成**：明确普通发送（候选规划）、指定 Agent、正式运行确认三种 API 语义；
+2. **已完成**：修复用户 `query` 到 Agent 节点 prompt/input binding 的链路，支持 `inputBindings` 和目标 Agent 投影；
+3. **已完成**：运行中的节点状态和 `node.output.delta` 映射到前端，终态清除 loading；
+4. **已完成**：候选流程卡片、右侧画布加载/编辑、图校验、确认后冻结快照并创建唯一正式 run；
+5. **已完成**：Human Assist 卡片按 `formSchema` 渲染、提交结构化值/自然语言补充，并用一次性令牌恢复原 run；
+6. **待完成**：单 Agent、两并行 Agent、人工暂停工作流的浏览器端端到端验收。
+
+### 阶段 B：模板化多智能体研究（进行中）
+
+1. **部分完成**：已有 Agent/技能/数据源权限目录；仍需补全 Role Catalog 的角色元数据与输入输出 schema；
+2. **部分完成**：受约束 Planner 已只对固定安全策略排序和组图；尚未有独立 `task_planner` 节点类型；
+3. **部分完成**：已引入 `EvidencePack` 与 `evidence_normalizer`，并接入并行调研候选图；仍需证据去重、质量评分和更丰富的多视角模板；
+4. **已完成**：将 Deep Research 包装成 `deep_research_write` 节点，并接入并行调研候选图（`调研 → Evidence Pack → 综合分析 → 深度研究报告`）；相同主题、证据快照和写作配置会复用同一持久化 Job，任一输入变化都不会复用旧报告；
+5. **部分完成**：报告 Markdown 已作为 run artifact，并通过工作流 SSE 流式显示；前端可直接调用统一 Word 导出接口下载正式 `.docx`，不改写制品；仍需引用质量/去重和浏览器端端到端验收。
+
+### 阶段 C：可控的人机协同与修订
+
+1. **部分完成**：已实现终态、无循环图的完成 Agent/Skill 的定点反馈；通过下游闭包重跑、上游 node-run 复用和稳定幂等键保留审计关系；
+2. **部分完成**：运行中输入新方向已有安全的“停止旧 run → 原任务 + 调整重新规划”前端闭环；仍需 `ChangeRequest` / 独立 revision 表、同一运行内的局部调整、循环图、Deep Research/有外部副作用节点的专门确认策略，以及产物版本对比；
+3. **部分完成**：对话区已在完成的智能体消息旁呈现“调整此分析”，提交后切换到新 revision run；仍需在历史/画布中显式展示复用与版本差异；
+4. **部分完成**：已有取消、重试、断线重连、重复反馈的回归测试；仍需浏览器端端到端验收和多用户/有副作用技能覆盖。
+
+### 阶段 D：受约束的动态子图（可选）
+
+仅当固定模板无法覆盖真实任务后再实施：引入 `PlanSpec` 编译器、配额限制、拓扑/权限校验和动态子图审计。不要把该阶段作为修复当前“消息走不通”的前置条件。
+
+## 13. 验收标准
+
+### 13.1 功能验收
+
+- 用户发送一句任务后，任一正在运行 Agent 在数秒内出现状态变化，首个文本增量能在模型完成前显示；
+- 并行 Agent 同时高亮，连线动画只对应真实的 `running` 状态；
+- 用户补充预算/周期等字段后，能恢复同一 run，而非创建新 run；
+- 用户对某分析节点提出修改后，只有该节点、其下游合并和报告节点重跑，其他收集结果可复用；
+- 报告包含可回溯证据/引用，且可下载为 artifact；
+- 停止运行会取消进行中的子任务并让所有 loading 进入明确终态；
+- SSE 断开重连后，消息、节点状态和报告正文不重复、不缺失、顺序正确。
+
+### 13.2 安全与可运维验收
+
+- Planner 无法调用未在当前空间授权的技能、数据源或模板；
+- 每一项外部副作用都有操作者、授权来源、输入摘要、输出和事件审计；
+- 每个 run/revision 都可还原 graph snapshot、计划、节点输入输出、人工提交和 artifact；
+- 并发数、单次运行成本、超时、重试次数、报告任务数量均有配额；
+- 失败事件向用户展示可理解原因，详细堆栈仅在受控诊断日志中可见。
+
+## 14. 最小闭环建议
+
+先不要尝试让一个总控 Agent 任意编排所有节点。最小可用闭环应为：
+
+```text
+对话输入
+  → task_planner（选择固定“研究报告”模板）
+  → [资料收集 Agent A || 资料收集 Agent B]
+  → evidence_normalizer
+  → analysis_agent
+  → human_assist（仅在关键事实缺失时）
+  → deep_research_write
+  → report_qa / artifact 输出
+```
+
+这个闭环能直接验证当前最关键的产品承诺：用户输入确实进入节点、过程实时可见、用户可在中途补充或纠偏、最终能得到来源可追溯的报告。稳定后再扩展角色数量、技能生态和动态图能力。

+      大屏汇报模版 A · 深蓝科技炫光风（动画精简版）
+      ============================================================
+      · 1920×1080 固定画布，JS 自动等比缩放，任意分辨率大屏/投影直接全屏打开即可
+      · 零依赖单文件：不需要网络、不需要构建，双击即可运行
+      · 动画策略（低负载，弱机/集显也可流畅播放）：
+        1) 图表最终状态由脚本同步直出（柱高/进度/弧长直接写内联样式），
+           动画只是从隐藏到最终态的一次性特效，不依赖 JS 定时链
+        2) 持续循环动画只保留 9 个，且全部只动 transform / opacity（GPU 合成）：
+           KPI 图标虚线环旋转×4 / LIVE 呼吸灯 / 仪表盘内环旋转 /
+           雷达扫掠+虚线环 / 趋势线流光光晕
+        3) JS 循环仅 4 个且限帧：粒子星网(44点/30fps) / 趋势流光点(30fps) /
+           预警纵向滚动(60fps) / 底部跑马灯(60fps)
+        4) 已删除：全屏扫描光束、标题流光、面板跑灯与角标呼吸、进度条流光、
+           柱体闪烁、翼线扫光、LOGO 呼吸、信号点漂移与闪烁等重绘型动画
+      · 智能体填充方式（弱模型友好）：
+        1) 标题、面板名称等文案：直接全局替换 HTML 里的中文文本
+        2) 所有数字、图表、列表：只改页面底部 <script> 里的 reportData 对象
+        3) 不要改 CSS 类名与页面结构，所有动画会自动生效
