+
+## 0. 现状与架构事实（动手前必读）
+
+研究自现有代码，决定了整套方案的形态。**关键结论：当前编排循环跑在前端，离开页面即中断。**
+
+### 0.1 前端现状
+
+| 事实 | 位置 |
+|------|------|
+| Step2 编排循环（leader → 顺序派 special → leader … 直到 `dispatched===[]` 共识 / `MAX_CYCLES=8`）**完全由前端 hook 驱动** | `src/roundtable-planning/hooks/useStep2Orchestration.ts:992-1204`（recommend）、`1228-1439`（chain） |
+| 循环由 `currentStep===2` 的 `useEffect` 启停；离开 Step2 的 cleanup 会 `orchestrationCancelRef.current=true` + `abortAllInFlight()` 中断 | `useStep2Orchestration.ts:1468-1541`（尤其 cleanup `1534-1537`、`1471-1477`） |
+| 共识判定：`leaderRes.dispatched.length===0` → `setHasConsensus(true)` | `useStep2Orchestration.ts:1091-1099` |
+| 进入 Step3：手动点按钮，前置 `hasConsensus===true` | `Step2Panel.tsx:370-381`、`RoundtablePlanningPage.tsx:586-595` |
+| Step3「结果绘制」：前端流式调 `roundtable-report` 智能体，写出 `outputs/方案总览.html`，`phase→"done"` 即完成 | `src/roundtable-planning/hooks/useStep3Report.ts:36,51,165,560-596,636-652` |
+| 草稿持久化：`/api/roundtable-drafts`，含 step1/step2/step3 三段快照 + `furthestStep(1|2|3)`，**无显式 status 字段** | `src/roundtable-planning/api/drafts.ts:25-110,112,184-225` |
+| 历史下拉 UI（触发按钮 + 列表 + 重命名/删除） | `RoundtablePlanningPage.tsx:771-892` |
+| 自动保存触发点（Step1 回复完 / Step2 每轮气泡收尾 / Step3 报告保存 / 步骤前进） | `useDraftPersistence.ts:248-316` |
+| 加载草稿恢复：`handleLoadDraft` → `getDraft` → `cancelAllStreams` → hydrate → `setCurrentStep(furthestStep)` | `useDraftPersistence.ts:308-368` |
+
+### 0.2 后端现状
+
+| 事实 | 位置 |
+|------|------|
+| `/api/multi-agent/init`：为各席位并行建 thread + 单例总控 `roundtable-coordinator`，SSE 返回 `seat_ready`/`coordinator_ready`/`init_done(thread_ids)` | `app/gateway/routers/multi_agent.py:647-823` |
+| `/api/multi-agent/run/stream`：驱动**单轮** leader 或 special 的 LLM 执行，末尾 JSON 帧 `status`（派活列表 / `[]` 共识 / `clarification` / `error`） | `multi_agent.py:1076-1142` |
+| `/api/multi-agent/report/init`：为 Step3 报告建 thread | `multi_agent.py`（report/init） |
+| **后端不存在编排循环**——leader 派活由前端解释后再逐个发 `run/stream`；后端只做单轮执行 + 把派活/完成「广播」追加进各 thread 历史消息 | `multi_agent.py:24-29,487-502,1108-1142` |
+| 派活格式：`agent_orchestration` 工具调用 `{agent_name, task}`（旧式 bash 解析兼容） | `multi_agent.py:525-552` |
+
+### 0.3 可复用模板：AI 写作的「后台多阶段流程」
+
+AI 写作已经把「后台跑多阶段流程 + 前端 SSE 订阅 + 可 resume + 定时清理」跑通了，**圆桌后台作业直接照搬这套**：
+
+| 模板要素 | 位置 |
+|------|------|
+| LangGraph 图驱动多阶段（researching/writing_outline/writing_draft/reviewing/…），条件路由推进，`interrupt()` 暂停点等用户输入 | `packages/harness/deerflow/agents/ai_writing/graph.py`、`nodes/*`（`pause_material_confirm` 等 `45-290`） |
+| Session 持久化表 `ai_writing_sessions`：`id/user_id/title/status/draft_*/transcript(LONGTEXT)/...`，`status∈{in_progress,done,error}` | `packages/harness/deerflow/persistence/ai_writing_sessions/model.py:14-39` |
+| `transcript` 用 `PortableLongText`（MySQL LONGTEXT，避开 64KB），时间用 `BeijingDateTime` | 同上 `27-38` |
+| 进度走 LangGraph Server 标准流 `stream_mode=["messages-tuple","values"]`，**graph 在 langgraph runtime 里跑，任意 worker 可 join stream**（这是后台健壮性的关键） | `ai_writing.py:1-17`、`langgraph.json:16-18` |
+| Checkpointer 共享 `AsyncSqliteSaver`，落 `.deer-flow/data/checkpoints.db`（需挂数据卷） | `runtime/checkpointer/async_provider.py` |
+| Cleanup cron（leader 文件锁、活跃保护、先删 CP 再删 DB、admin 手动触发） | `app/gateway/ai_writing_cleanup.py:26,34-59,111-135,193-215,307-367` |
+| **多 worker 坑**：模块级内存 dict（`_event_queues`）每 worker 一份会丢会话；SSE 进程内直调会整段 buffer。解法：状态进 DB+checkpointer、SSE 走真 TCP loopback `127.0.0.1`（`trust_env=False` 禁代理） | `multi_agent.py:271-293`、`AIWritingPage.tsx` 文件头注释 §3/§5 |
+
+### 0.4 决策（已与产品确认）
+
+1. **后端真后台执行**：把编排循环搬到后端 run，刷新 / 关页 / 换设备都不中断。
+2. **流程图节点 = 智能体派活链路**：横向排列的席位节点，正在发言的节点 + 连接线加载动画。
+
+> ⚠️ **本方案最大的工作量在 Phase 2**：把目前跑在前端 TS 里的编排循环（`runOrchestration`/`runChainOrchestration`）
+> 移植成一个后端 **LangGraph「圆桌总控编排图」**。这是与 AI 写作一致、可在 LangGraph runtime 里
+> 后台跑且天然 checkpoint 的健壮路径。下文每个阶段都给出验收标准，可独立提测。

+
+**核心思路**：后台作业 = 一个 LangGraph 图的一次 run。图节点内部复用现有的单轮执行能力
+（`multi_agent.py` 里 leader/special 的 run 逻辑），把「解释派活 → 顺序派活 → 回到 leader」的
+循环从前端搬进图节点。前端从「驱动者」退化为「观察者」：通过 SSE 订阅进度渲染。

+```
+
+### 2.3 派活链路节点 `DispatchChainNode`（流程图核心数据）
+
+```ts
+interface DispatchChainNode {
+  agentId: string;        // 席位 agent_id（小写）
+  name: string;           // 显示名
+  avatarType: string;     // 复用 getAvatarTypeFor(agentId, index) → 决定颜色
+  order: number;          // 横向排列次序（chain 模式=链条顺序；recommend 模式=席位/发言顺序）
+  state: 'pending' | 'active' | 'done';  // 节点状态（驱动颜色/动画）
+  lastSpokeCycle?: number;               // 最近发言轮次（可选，做 tooltip）
+}
+```
+
+### 2.4 进度事件 `JobProgressEvent`（SSE 推送的归一化事件）
+
+```ts
+type JobProgressEvent =
+  | { type: 'status';   status: JobStatus }
+  | { type: 'phase';    phase: JobPhase; cycle: number }
+  | { type: 'chain';    nodes: DispatchChainNode[] }           // 派活链路全量/增量
+  | { type: 'active';   agentId: string | null }               // 当前发言席位（null=总控/无）
+  | { type: 'consensus'; percentage: number }
+  | { type: 'dialogue'; bubble: Step2DialogueLike }            // 新增/收尾的对话气泡（供「查看」实时渲染）
+  | { type: 'clarification'; question: string }                // 命中澄清
+  | { type: 'done';     step3: DraftStep3Snapshot }            // 终态：最终报告快照
+  | { type: 'error';    detail: string };
+```
+
+> SSE 通道可直接复用 LangGraph Server 的 `values` 流（图状态快照），由前端 hook 把 `values`
+> 映射成上述归一化事件；也可在路由层做映射后再下发。**推荐前端映射**（少一层后端耦合）。
+
+### 2.5 作业记录 `RoundtableJob`（持久化 + 列表展示）
+
+```ts
+interface RoundtableJob {
+  id: string;
+  draftId: string;            // 关联的草稿
+  userId: string;
+  status: JobStatus;
+  phase: JobPhase;
+  cycle: number;              // 当前轮次（0..MAX_CYCLES）
+  dispatchChain: DispatchChainNode[];
+  activeAgentId: string | null;
+  consensusPercentage: number;
+  pendingClarification: string | null;
+  threadIds: Record<string,string> | null;  // 复用 ThreadIdMap

+  orchestrationMode: 'recommend' | 'chain';
+  chain?: { id: string; title: string } | null;
+  error: string | null;
+  createdAt: string;
+  updatedAt: string;
+}
+```
+
+---
+
+## Phase 1 —— 后端：圆桌作业持久化模型
+
+**目标**：建一张 `roundtable_jobs` 表（仿 `ai_writing_sessions`），存作业状态/阶段/派活链路，
+并在 `roundtable_drafts` 列表里能 join 出当前作业状态。
+
+**涉及文件（新增/改）**
+- 新增 `packages/harness/deerflow/persistence/roundtable_jobs/model.py`（ORM 模型，仿 `ai_writing_sessions/model.py:14-39`）
+- 新增 `.../roundtable_jobs/sql.py`（Repository：`create / get / update_progress / list_by_user / list_older_than / delete`，仿 `ai_writing_sessions/sql.py`）
+- 新增 alembic 迁移 `persistence/migrations/versions/<date>_create_roundtable_jobs.py`
+- 改 `roundtable_drafts` 的列表查询：返回里带上 `status`/`jobId`（LEFT JOIN roundtable_jobs，或在 draft 行上冗余一个 `status` 字段，二选一，见下）
+
+**步骤**
+1. 字段设计（对齐 §2.5）：`id(PK)`、`draft_id`、`user_id`、`status`、`phase`、`cycle(Int)`、
+   `dispatch_chain(PortableLongText/JSON)`、`active_agent_id`、`consensus_percentage(Int)`、
+   `pending_clarification(Text)`、`thread_ids(JSON)`、`coordinator_name`、`orchestration_mode`、
+   `chain(JSON)`、`error(Text)`、`created_at/updated_at(BeijingDateTime)`。
+2. `dispatch_chain` / `thread_ids` / `chain` 用 `PortableLongText` 存 JSON 字符串，repo 层序列化。
+3. 列表 join：给 `DraftMeta` 增加 `status?: JobStatus` 与 `jobId?: string`。
+   **推荐方案**：草稿与作业 1:1（一个草稿最多一个活跃作业），在 draft 列表查询 LEFT JOIN
+   `roundtable_jobs` 取最新作业的 `status`。
+4. 索引：`(user_id, updated_at)`、`(draft_id)`、`(status)`（cleanup/列表用）。
+
+**验收**
+- 迁移可 `alembic upgrade head` 跑通，MySQL 上 `dispatch_chain` 为 `longtext`。
+- 单测：create→update_progress→get 往返；`list_by_user` 按 `updated_at` 倒序；`list_older_than` 分批。
+
+---
+
+## Phase 2 —— 后端：圆桌总控编排 LangGraph 图（核心 / 最大工作量）
+
+**目标**：把前端的编排循环移植成一个后端 LangGraph 图，可在 LangGraph runtime 里后台跑、天然
+checkpoint，一路跑到 Step3 绘制完成。
+
+**涉及文件（新增）**
+- `packages/harness/deerflow/agents/roundtable_orchestrator/graph.py`（图装配，仿 `ai_writing/graph.py`）
+- `.../roundtable_orchestrator/state.py`（图状态 schema：intent、selectedAgents、threadIds、coordinatorName、
+  mode/chain、dialogues、dispatchChain、activeAgentId、cycle、consensus、phase、step3 等）
+- `.../roundtable_orchestrator/nodes/*.py`（各节点）
+- 在 `langgraph.json` 注册新 assistant `roundtable_orchestrator`（仿 ai_writing assistant 注册，参考 `langgraph.json:16-18`）
+
+**图节点设计（把前端循环逐段翻译过来）**
+
+| 节点 | 职责 | 对应前端逻辑 |
+|------|------|------|
+| `init` | 复用 `_create_thread_direct` 批量建席位 thread + 总控就绪（或接收前端已建好的 `threadIds` 直接用） | `useStep2Orchestration.ts:1485-1531` / `multi_agent.py:647-823` |
+| `leader_call` | 跑一轮总控（agent_type=leader），拿 `status`（派活列表 / `[]` / `clarification`） | 单轮逻辑 `multi_agent.py:1076-1142` |
+| `route_after_leader`（条件边） | `clarification`→`interrupt`；有派活→`dispatch_seats`；`[]`→`consensus` | `useStep2Orchestration.ts:1091-1181` |
+| `dispatch_seats` | **顺序**派活：对 dispatched 里每个席位依次跑 special run；每开始一个就更新 `activeAgentId` + 进度持久化 | `useStep2Orchestration.ts:1101-1181`（务必串行，勿并行，详见前端 §5.4 注释） |
+| `clarification_pause` | `interrupt()` 挂起，`status→awaiting_input`，写 `pending_clarification` | 仿 ai_writing `pause_*` `45-290` |
+| `consensus` | `setHasConsensus`、`consensus=100`，落库后进入 `report_draw` | `1091-1099` |
+| `report_draw` | 跑 `roundtable-report`（先 report/init 建 thread），流式写 `outputs/方案总览.html`，产出 `DraftStep3Snapshot` | `useStep3Report.ts:91-149,636-652,560-596` |
+| `done` | `status→done`、写 `step3` 进作业 + 回写草稿 step3 快照 | `RoundtablePlanningPage.tsx:613-617` |
+
+**关键实现要点**
+1. **复用单轮执行**：节点内部不要重写 LLM 调用，抽出 `multi_agent.py` 里 leader/special/report 的
+   单轮 run 为可被图节点直接 `await` 的内部函数（去掉 HTTP 层，进程内调 LangGraph）。
+2. **派活广播**：保留现有把「总控给 X 派了活 / X 完成」追加进各 thread 历史的广播
+   （`multi_agent.py:487-502`），让席位读到全局上下文。
+3. **MAX_CYCLES 兜底**：图里维护 `cycle`，≥8 强制收敛（对齐 `roundtable-constants.ts:13`）。
+4. **chain 模式**：`orchestration_mode==='chain'` 时按 `chain.seats` 固定顺序派活，跳过总控自由决策的
+   部分（对齐 `runChainOrchestration` `1228-1439`）。
+5. **进度落库**：每个节点结束 `update_progress(jobId, {phase, cycle, dispatchChain, activeAgentId,
+   consensus, dialogues_delta})`，前端 SSE 才有实时数据。
+6. **dialogues 累积**：把每轮气泡写进图状态 `dialogues`，既供「查看」实时渲染，也供作业结束回写草稿 step2。
+
+**验收**
+- 用脚本（仿 `scripts/probe_ai_writing_assistant.py`）直接对图发起一次 run，不开前端，能从 intent +
+  selectedAgents 一路跑到写出 `方案总览.html`，作业 `status` 终态 `done`。
+- 命中 clarification 时图 `interrupt`，`status=awaiting_input`，`pending_clarification` 有值。
+- chain 模式按链条顺序派活，recommend 模式由总控自由派活，两条路径都能收敛。
+
+---
+
+## Phase 3 —— 后端：作业控制 + 进度 SSE 接口
+
+**目标**：暴露 start/get/stream/resume/cancel，后台 run 走 LangGraph Server（任意 worker 可 join）。
+
+**涉及文件（新增/改）**
+- 新增 `app/gateway/routers/roundtable_jobs.py`（仿 `ai_writing.py` 的 CRUD + 控制壳）
+- 在 gateway `app.py` 注册路由
+- 新增 `app/gateway/roundtable_jobs_cleanup.py`（仿 `ai_writing_cleanup.py`）+ 在启动处挂 cron
+
+**接口契约**
+
+| 方法 | 路径 | 说明 |
+|------|------|------|
+| `POST` | `/api/roundtable-jobs` | 入参：`{draftId, intent, selectedAgents, threadIds?, coordinatorName?, model, orchestrationMode, chain?}`。建作业记录(`queued`) + 启动图 run（LangGraph Server thread），返回 `RoundtableJob` |
+| `GET` | `/api/roundtable-jobs/{id}` | 作业快照（轮询兜底 / 弹窗首帧） |
+| `GET` | `/api/roundtable-jobs/{id}/stream` | SSE 进度流：透传图 `values`/`messages-tuple`，或映射成 §2.4 事件下发。**走真 TCP loopback**（`multi_agent.py:271-293`），禁代理 |
+| `POST` | `/api/roundtable-jobs/{id}/resume` | 入参 `{answer}`，回填 clarification → 图 resume，`status→running` |
+| `POST` | `/api/roundtable-jobs/{id}/cancel` | 取消图 run，`status→cancelled` |
+| `GET` | `/api/roundtable-jobs?draftId=` | 按草稿查活跃作业（页面恢复用） |
+| `POST` | `/api/roundtable-jobs/admin/cleanup` | 管理员手动清理（仿 ai_writing admin cleanup `307-367`） |
+
+**多 worker 健壮性（务必遵守，照搬 ai_writing 教训）**
+- 作业状态只存 **DB + checkpointer**，**不要**用模块级内存 dict 存 per-session 状态。
+- SSE 必须经真 TCP `127.0.0.1` loopback，不能 `httpx.ASGITransport(app=...)` 进程内直调（会整段 buffer）。
+- 图 run 跑在 LangGraph runtime（独立于处理 HTTP 的 worker），刷新/换 worker 都能重新 join stream。
+- 数据卷：`.deer-flow/data/checkpoints.db` 必须挂出，否则容器重启丢状态。
+
+**验收**
+- `POST /start` 后立刻 `GET /{id}` 能拿到 `queued/running`；关掉 SSE 再重连能继续收进度。
+- 杀掉发起 start 的 worker（或多 worker 轮询），`resume`/`stream` 仍命中同一作业。
+- cleanup 干跑：活跃作业永不删，先删 CP 再删 DB。
+
+---
+
+## Phase 4 —— 前端：作业 API 客户端 + 数据模型扩展
+
+**目标**：前端有一层干净的作业 API 与类型，历史列表能拿到 status。
+
+**涉及文件（新增/改）**
+- 新增 `src/roundtable-planning/api/roundtable-jobs.ts`：
+  ```ts
+  export async function startJob(payload: StartJobPayload): Promise<RoundtableJob>
+  export async function getJob(id: string): Promise<RoundtableJob>
+  export function streamJob(id: string, on: (e: JobProgressEvent) => void): () => void  // 返回 unsubscribe
+  export async function resumeJob(id: string, answer: string): Promise<void>
+  export async function cancelJob(id: string): Promise<void>
+  ```
+  - `streamJob` 复用项目现有 SSE/`streamMultiAgent` 的封装方式（`api/multi-agent.ts:403+`），把
+    LangGraph `values` 映射成 §2.4 的归一化事件。
+- 改 `src/roundtable-planning/api/drafts.ts`：`DraftMeta` 增 `status?: JobStatus; jobId?: string`
+  （`drafts.ts:76-83` + 字段映射 `122-178` 加 snake_case 转换）。
+- 新增 `src/roundtable-planning/lib/job-types.ts`：把 §2.1–2.5 的类型集中导出。
+
+**验收**：`pnpm typecheck` 通过；`getJob`/`streamJob` 能拉到 Phase 3 的数据。
+
+---
+
+## Phase 5 —— 前端：Step2「后台挂起」按钮
+
+**目标**：Step2 顶栏/底栏加按钮，点击把当前任务交给后端后台跑，前端停止本地循环、转为观察者。
+
+**涉及文件（改）**
+- `src/roundtable-planning/components/Step2Panel.tsx`（按钮放在现有「进入第三步」附近 `370-381`）
+- `src/roundtable-planning/pages/RoundtablePlanningPage.tsx`（接线 + 观察者模式）
+- `src/roundtable-planning/hooks/useStep2Orchestration.ts`（暴露「停止本地循环并交后台」的方法）
+
+**步骤**
+1. Step2Panel 加「⏼ 后台挂起」按钮，`onBackgroundSuspend` 回调。
+2. 页面 `handleBackgroundSuspend`：
+   - `ensureDraft(2)` 拿到 `draftId`（`useDraftPersistence.ts` ensureDraft）。
+   - 收集当前状态：`intentReady`、`selectedAgents`、`threadIds`、`coordinatorName`、`model`、
+     `orchestrationMode`、`chain`（全部来自 `step2`/`step1` 现有状态）。
+   - `startJob(...)` → 拿到 `jobId`。
+   - **停止前端本地编排**：调用 `step2.stopOrchestration()` + 置一个 `backgroundedJobId` 标记，
+     让 `currentStep===2` 的 useEffect **不再自启本地循环**（在 `useStep2Orchestration.ts:1468-1541`
+     的启动条件里加 `&& !backgrounded`）。
+   - toast「已转入后台，可离开页面，任务会自动跑到结果绘制完成」。
+   - 刷新历史列表（`drafts` 重新拉，进行中项即出现 spinner）。
+3. **观察者模式**：若当前停留在 Step2 且该 draft 有 running 作业，订阅 `streamJob`，把进度事件渲染成
+   对话气泡/活动席位（复用现有 Step2 渲染），而不是本地驱动。
+
+**注意：避免「双跑」**——后台已接管后，前端绝不能再并行驱动同一批 thread。用 `backgroundedJobId`
+互斥；加载草稿时若发现有 running 作业，直接进观察者模式。
+
+**验收**：点「后台挂起」→ 可立即切到别的任务/路由；回来仍在跑；不会出现前后端同时派活。
+
+---
+
+## Phase 6 —— 前端：历史下拉框「进行中」加载动画
+
+**目标**：历史下拉里 `status==='running'`（或 `awaiting_input`）的草稿条目显示加载动画；点击进行中
+条目不直接 load，而是打开流程图弹窗。
+
+**涉及文件（改）**
+- `src/roundtable-planning/pages/RoundtablePlanningPage.tsx` 的 `HistoryDropdown`（`771-892`）
+
+**步骤**
+1. 列表项左侧名称前/后，按 `d.status` 渲染状态标记：
+   - `running` → 旋转的 `Loader2`（`animate-spin`）+「进行中」。
+   - `awaiting_input` → 呼吸点 +「待澄清」（琥珀色）。
+   - `done`/无 → 维持现状（显示 `Step {furthestStep}`）。
+   - `error` → 红点 +「出错」。
+2. 点击行为分流：
+   - `running`/`awaiting_input` → `openDispatchChainModal(d.jobId)`（Phase 7），**不**直接 `onLoad`。
+   - 其它 → 维持 `onLoad(id)`。
+3. 列表需要 `status`，确保 Phase 4 的 `DraftMeta.status` 已就位；下拉打开时 `refresh()` 拉最新。
+
+**验收**：后台挂起后，历史下拉对应条目转圈；点击弹出流程图弹窗。
+
+---
+
+## Phase 7 —— 前端：派活链路流程图弹窗（横向 / 大弹窗 / 动画）
+
+**目标**：大弹窗，横向排列的智能体派活链路。节点 = 席位（图标 + 名称），不同颜色；正在发言的
+节点和它的连接线带加载动画；含「查看」按钮。
+
+**涉及文件（新增）**
+- `src/roundtable-planning/components/DispatchChainModal.tsx`
+
+**实现选型**：链路是「总控 → 席位序列」的线性结构 + 需要对**单个节点和单条连线**做精确动画，
+**推荐手写 flex 横向布局 + CSS 动画连接线**（轻、可控）。项目已装 `@xyflow/react@12`（带 `animated`
+边）作为备选，但手写对本场景的「节点 loading + 连线流动」更直接。
+
+**结构（手写方案草图）**
+```tsx
+<Dialog open={open} onOpenChange={onOpenChange}>
+  <DialogContent className="flex max-h-[88vh] flex-col gap-0 sm:max-w-5xl"> {/* 大弹窗 */}
+    <DialogHeader>… 任务标题 + 阶段标签（leader_thinking/dispatching/report_drawing…） …</DialogHeader>
+
+    {/* 横向链路：总控 ──▶ 席位1 ──▶ 席位2 ──▶ … ──▶ [共识] ──▶ [报告绘制] */}
+    <div className="custom-scrollbar overflow-x-auto py-8">
+      <div className="flex items-center gap-0 min-w-max px-6">
+        <CoordinatorNode active={phase==='leader_thinking'} />
+        {nodes.map((n,i)=>(
+          <Fragment key={n.agentId}>
+            <Connector active={n.state==='active'} />            {/* 活动连线：流动虚线动画 */}
+            <ChainNode node={n} />                               {/* 活动节点：彩色+脉冲光环 */}
+          </Fragment>
+        ))}
+        <Connector active={phase==='consensus'} />
+        <MilestoneNode label="共识" done={consensus===100} />
+        <Connector active={phase==='report_drawing'} />
+        <MilestoneNode label="报告绘制" active={phase==='report_drawing'} done={phase==='report_done'} />
+      </div>
+    </div>
+
+    <DialogFooter className="border-t pt-3 sm:justify-between">
+      <span className="text-xs text-muted-foreground">轮次 {cycle}/8 · {statusLabel}</span>
+      <Button onClick={onView}>查看</Button>   {/* Phase 8 */}
+    </DialogFooter>
+  </DialogContent>
+</Dialog>
+```
+
+**节点颜色**：`avatarType = getAvatarTypeFor(agentId, order)` → `chainTagClasses(avatarType)`
+（复用 `lib/business-chain.ts:56-72` + `lib/roundtable-constants.ts`），与业务链条卡片同一套色。
+
+**节点状态样式**
+- `pending`：灰色描边、低透明度。
+- `active`：席位色填充 + 外圈 `animate-ping`/脉冲光环 + 图标旋转或呼吸。
+- `done`：席位色实心 + 右上角 ✓。
+
+**连接线加载动画（active 连线）**：CSS 流动虚线（marching-ants）或渐变扫光：
+```css
+/* roundtable-planning.css 追加 */
+@keyframes chain-flow { to { background-position: 20px 0; } }
+.chain-connector--active {
+  background-image: linear-gradient(90deg, var(--brand-500) 50%, transparent 50%);
+  background-size: 20px 100%;
+  animation: chain-flow 0.6s linear infinite;
+}
+```
+
+**数据来源**：弹窗 mount 时 `getJob(jobId)` 取首帧，随后 `streamJob(jobId, onEvent)` 实时更新
+`nodes`/`activeAgentId`/`phase`/`consensus`/`cycle`；`done` 事件后停止动画、全节点置 `done`。
+弹窗关闭时 `unsubscribe`。
+
+**验收**：弹窗够大、横向滚动；活动席位节点和它左侧连线在动；阶段推进时高亮顺移；`done` 后静止。
+
+---
+
+## Phase 8 —— 前端：「查看」进入进行中任务并实时观察
+
+**目标**：弹窗「查看」→ 进入该任务，停在 Step2 实时看后台进度（气泡/活动席位随 SSE 刷新），
+跑完自动呈现 Step3 结果。
+
+**涉及文件（改）**
+- `RoundtablePlanningPage.tsx`（接 `onView`）
+- `useDraftPersistence.ts`（`handleLoadDraft` 增「带作业」分支）
+- `useStep2Orchestration.ts`（观察者渲染）
+
+**步骤**
+1. `onView`：关弹窗 → `handleLoadDraft(draftId)` 恢复该草稿到 Step2（`useDraftPersistence.ts:308-368`），
+   但**跳过本地编排自启**（识别到有 running 作业 → 进观察者模式，对齐 Phase 5 的互斥标记）。
+2. 订阅 `streamJob(jobId)`，把 `dialogue` 事件 append 进 `step2RoundtableDialogues`、`active` 事件
+   驱动 `activeSpeakerId` 高亮、`consensus` 更新百分比。
+3. 命中 `awaiting_input`：在 Step2 弹出澄清输入（复用现有 `pendingClarification` UI），用户回答 →
+   `resumeJob(jobId, answer)`（而非本地 `submitClarification`）。
+4. `done` 事件：用返回的 `DraftStep3Snapshot` 走 `hydrateStep3` + 允许切到 Step3 查看报告
+   （`useStep3Report.hydrateSaved` `708-767`）；作业列表该项变「已完成」。
+
+**验收**：从历史「查看」进入能实时看到后台在跑；澄清能在前端回答并续跑；跑完能看到最终报告。
+
+---
+
+## Phase 9 —— 边界、健壮性与收尾
+
+1. **双跑互斥**：任一 draft 同一时刻只允许一个执行者（前端本地 or 后台作业）。加载草稿/进入 Step2
+   前先 `GET /api/roundtable-jobs?draftId=`，有 running 就进观察者模式。
+2. **后台命中澄清**：`awaiting_input` 时历史下拉显示「待澄清」徽标；流程图弹窗显示「等待澄清」；
+   只有「查看」进去才能回答（或在弹窗里直接给一个回答框，调用 `resumeJob`）。
+3. **取消**：流程图弹窗/Step2 提供「停止后台」→ `cancelJob`，`status→cancelled`，前端可恢复本地编辑。
+4. **错误恢复**：`error` 事件展示 detail；允许「重试」= 重新 `startJob`（沿用已建 threadIds）。
+5. **MAX_CYCLES / 预算**：后台图内兜底（对齐前端 `MAX_CYCLES=8`），到顶强制收敛并照常进 Step3。
+6. **多 worker**：严格遵守 Phase 3 的「状态进 DB+checkpointer、SSE 走 loopback」；部署若多 worker
+   需 sticky 或全靠 DB 态（推荐后者）。
+7. **清理**：`roundtable_jobs` cleanup cron（活跃保护、先删 CP 再删 DB），与 draft 生命周期对齐。
+8. **历史列表性能**：draft 列表 join 作业 status 时注意 N+1；用一次 LEFT JOIN 取最新作业。
+

+# 多智能体「后台挂起」—— 当前状态、遗留问题与下次继续指南
+
+> 配套设计文档：`multi-agent-background-run-dev.md`（分 Phase 0-9 的总方案）。
+> 本文记录**截至本次会话的实际进展 + 还没解决的遗留问题**，方便下次直接续接。
+
+---
+
+## 一、整体状态：跑通到哪了
+
+「后台挂起」= Step2 把研讨交给后端**进程内驱动真模型**（leader→各席位→共识→报告），
+survive 刷新/关页，对话与报告作为一个 **run 写进草稿**（和手动跑同一存取），可在历史回看。
+
+**真网关已在本地验证可跑通**（2026-06-04 日志确认：roundtable-coordinator + 各席位 +
+roundtable-report 真调 deepseek、真搜索、跑到 report run success）。但还有几个**内容/产物层面的遗留问题**（见第三节）。
+
+### 已完成（可用）
+- ✅ 后端持久化：`roundtable_jobs` 表（迁移 `20260604_01` / `20260605_01` dialogues / `20260605_02` step3）。
+- ✅ 编排引擎 `packages/harness/deerflow/agents/roundtable_orchestrator/`（recommend + chain + 报告，纯逻辑可单测）。
+- ✅ 控制面 `app/gateway/routers/roundtable_jobs.py`：start/get/by-draft/stream(SSE)/resume/cancel/admin-cleanup。
+- ✅ 执行器 `app/gateway/roundtable_job_executor.py`：后台任务 + `set_current_user` + 生命周期 + **每轮把对话作为 `job-<id>` run 写进 `draft.step2.runs[]`（同手动存取）** + done 写 step3。
+- ✅ 真网关 `app/gateway/roundtable_inprocess_gateway.py`：`SimpleNamespace(app)` + `start_run` 进程内驱动 agent；复用 `multi_agent._extract_dispatch` 解析派活；checkpointer 读最终 messages。
+- ✅ 模拟网关 `roundtable_orchestrator/simulated_gateway.py`（不调真模型，前端联调用）。
+- ✅ 前端：`api/roundtable-jobs.ts`、`lib/job-types.ts`、Step2「后台挂起」按钮、历史下拉 loading、`DispatchChainModal`/`DispatchChainJobModal`（流程图 + 对话面板 markdown + 加宽 + 澄清作答 + 取消 + 查看）。
+- ✅ 上下文「广播」（inline）：席位/总控 prompt 带上「任务背景 + 前序各席位交付 + 别提问」约束（修「席位拿不到关键信息、反问用户、总控瞎编」）。
+- ✅ 后端测试：`tests/test_roundtable_jobs.py` / `test_roundtable_orchestrator.py` / `test_roundtable_job_executor.py` / `test_roundtable_jobs_api.py` 全过。
+
+---
+
+## 二、怎么启动 / 验证（每次开工先做）
+
+1. **开真网关**（默认是模拟网关）：已写进 `offline-backend-20260512/.env`：
+   ```
+   ROUNDTABLE_JOB_GATEWAY=inprocess
+   ```
+   启动日志应出现 `[roundtable-jobs] gateway = inprocess (real models)`。
+
+2. **必须用 `make gateway`（不带 --reload）跑后端！**
+   `make dev` 的 `--reload` 监视 `backend/` 目录，agent 运行时往 `.deer-flow/` 写文件
+   （memory.json / checkpoint / 沙箱输出）会触发热重载，**把长时后台任务杀掉**。
+   （改进项：给 uvicorn 加 `--reload-exclude '.deer-flow/*'`，或始终用 `make gateway`。）
+
+3. **直接查库验证**（最有效，PowerShell 控制台是 GBK，导出到文件看中文）：
+   ```bash
+   cd offline-backend-20260512/backend
+   # 查最新作业的 dialogues / step3
+   PYTHONPATH=. uv run python -c "import sqlite3,json; con=sqlite3.connect('.deer-flow/data/deerflow.db'); ..."
+   ```
+   - 作业表：`.deer-flow/data/deerflow.db` → 表 `roundtable_jobs`（`dialogues`/`step3` 列）。
+   - 草稿表：`roundtable_drafts` → `step2` 列里应有 `runs[ {id:"job-<jobId>", jobId, jobStatus, step2RoundtableDialogues:[...], step3:{...}} ]`。
+
+4. **前端验证**：后台挂起 → 等跑完 → 从历史加载该草稿 → Step2 应显示后台研讨完整对话（走现有 `normalizeStep2Runs`/`hydrateStep2Run`）。
+
+---
+
+## 三、遗留问题（下次重点，已按优先级排）
+
+### P0 —— 报告 agent 不写 HTML 文件（结果绘制拿不到产物）
+- **现象**：后台报告 run 跑完，日志 `report html: no .html found in ...threads/<id>/user-data/outputs`；
+  `run.step3.html` 回退成报告 agent 的**纯文字**（不含 `<html>`），第3步画不出东西。
+- **已做**：`build_report_prompt`（`roundtable_orchestrator/engine.py`）已对齐前端
+  `useStep3Report.buildReportPrompt`，明确「用 write_file 写入 /mnt/user-data/outputs/方案总览.html」；
+  `_read_report_html`（`roundtable_inprocess_gateway.py`）已改为扫 outputs 目录任意 `.html`。
+- **仍没解决**：报告 agent（deepseek-chat）还是没调 `write_file`。
+- **下次怎么查**：
+  1. 对比**前端那条能写出 HTML 的报告 run** 的确切调用（`useStep3Report.ts` 里 `streamMultiAgent`
+     调 `/api/multi-agent/run/stream` 的 body：`agent_type`/`excluded_tools`/`context` 等），
+     和后台 `_run_agent_turn`（`roundtable_inprocess_gateway.py`，agent_name=roundtable-report，
+     `excluded_tools=_REPORT_EXCLUDED`）逐项比对，找出差异（怀疑 reasoning_effort / thinking /
+     某个 context 字段 / recursion 步数导致它没走到 write_file）。
+  2. 看报告 run 的最终 messages（checkpoint）里有没有 write_file 的 tool_call（被 dangling 截断？）。
+  3. 报告 agent 的 SOUL：`app/gateway/routers/_roundtable_seed/roundtable-report/SOUL.md`——确认它默认行为。
+
+### P1 —— 内容质量（本次刚加 inline 广播，待真机验证）
+- **已做**：席位/总控 prompt 注入「任务背景 + 前序交付 + 别提问」。
+- **待验证**：真机跑一次，看席位是否基于真实上下文产出（不再反问/凭记忆瞎编）。
+- **若 inline 不够**：考虑实现**真·thread 广播**（像 `multi_agent._append_thread_message` 那样把
+  「用户意图 / 派活 / 各席位交付」追加进各 thread 历史）。进程内要避开 HTTP loopback 鉴权，
+  得用 checkpointer 直接 append human 消息（参考 `threads` 路由 POST `/state` 的内部逻辑）。这块较重，先看 inline 够不够。
+
+### P2 —— 对话「没有步骤（steps）」
+- **现象**：手动跑的气泡带工具调用步骤卡（`onPhaseChange` → `appendStepIfNew` → `Step2Dialogue.steps`）；
+  后台对话只存了最终正文，没有 steps。
+- **下次怎么做**：后台 `_run_agent_turn` 跑完后，从 checkpoint 的 messages 里抽出 tool_calls，
+  映射成 `Step2Dialogue.steps`（`{id,key,label,ts,args}`），在执行器 `_to_step2_dialogue` 里带上。
+  纯展示增强，不影响内容/报告。
+
+### P3 —— 双跑浪费 + --reload 坑（工程健壮性）
+- 进 Step2 时前端会自动跑一遍本地研讨（真模型、真线程）；点后台挂起后前端那条 run 在后端还会跑完
+  （`stopOrchestration` 只断客户端、停不了后端 run）→ 和后台作业短暂双跑、双倍 token。
+  - 优化方向：进 Step2 改成「显式开始」而非自动跑；或后台挂起时真正 cancel 前端那条 run。
+- `make dev` 的 `--reload` 会杀后台任务（见第二节）；改进项：`--reload-exclude '.deer-flow/*'`。
+
+---
+
+## 四、关键文件清单（下次定位用）
+
+**后端**
+| 文件 | 作用 |
+|------|------|
+| `app/gateway/roundtable_inprocess_gateway.py` | 真网关：进程内驱动 leader/seat/re 编排循环 + `build_report_prompt` + inline 广播（`_seat_message`/`_deliveries_block`） |
+| `.../roundtable_orchestrator/progress.py` | 进度落库 + `on_dialogue` 每轮回调 |
+| `.../persistence/roundtable_jobs/` | job 表 model/sql |
+| `app/gateway/deps.py` | `ROUNDTABLE_JOB_GATEWAY` 选网关 + 注入 executor（draft_store） |
+
+**前端**
+| 文件 | 作用 |
+|------|------|
+| `src/roundtable-planning/api/roundtable-jobs.ts` | 作业 API + SSE |
+| `src/roundtable-planning/lib/job-types.ts` | 类型（RoundtableJob/JobDialogue/...） |
+| `src/roundtable-planning/components/DispatchChainModal.tsx` / `DispatchChainJobModal.tsx` | 流程图弹窗 + 对话面板 |
+| `src/roundtable-planning/pages/RoundtablePlanningPage.tsx` | 后台挂起按钮、历史下拉、**runs[] 多运行模型**（`hydrateStep2Run`/`getStep2SnapshotWithRuns`/`normalizeStep2Runs`） |
+| `src/roundtable-planning/api/drafts.ts` | `DraftStep2RunSnapshot`（带 jobId/jobStatus/step3） |
+
+---
+
+## 五、关键架构事实（避免重复踩坑）
+
+1. **真网关进程内驱动**：`start_run(body, thread_id, SimpleNamespace(app=app))` + `set_current_user`，
+   不走 HTTP（loopback 调 `/api/multi-agent/*` 不可行：`_auth_headers` 只转发用户 token + owner check）。
+2. **后台作业首启自建全新线程**（`StartParams.is_resume`），绝不复用前端本地研讨的线程（会撞 409）。
+3. **存取统一**：后台作业 = `draft.step2.runs[]` 里一个带 jobId 的 run，和手动跑同一存取/hydrate 路径，
+   **不要再开 observe/回显分支**（之前试过，被否）。
+4. **聊天记录确实存上了**（job.dialogues + draft 的 run）；之前"没存上"是测了旧代码 / 看的是前端本地残缺数据。
+5. 多 worker / SSE：状态进 DB、SSE 走 DB 轮询；真网关进程内无 loopback。

+# 多智能体会商 Step2 多结果线方案
+
+## 背景
+
+当前「多智能体会商 / 多智能体规划」里，一个历史草稿只保存一份 `step2` 快照。用户从历史记录加载草稿后，如果再次点击「智能体推荐」并在弹窗里点击「进入研讨」，新的 Step2 研讨会继续写入同一份 `draft.step2`，结果是第一次生成内容会被第二次生成内容覆盖，或者页面只能展示最新一次结果。
+
+产品期望是：
+
+- 用户从历史记录进入已有草稿时，进入第二步后，左下角能看到第一次生成结果。
+- 用户再次点击「智能体推荐」并点击「进入研讨」时，要开启一条新的研讨结果线。
+- 第二次生成结果显示在左下角，但不能影响第一次生成结果。
+- 用户之后再次查看同一个历史草稿时，可以分别查看第一次生成结果和第二次生成结果。
+
+因此，这个需求的核心不是简单增加一个展示区域，而是把 Step2 从「单结果」升级为「一个草稿下多条研讨 run」。
+
+## 现状
+
+相关位置：
+
+- `src/roundtable-planning/api/drafts.ts`
+- `src/roundtable-planning/pages/RoundtablePlanningPage.tsx`
+- `src/roundtable-planning/hooks/useStep2Orchestration.ts`
+- `src/roundtable-planning/components/Step2Panel.tsx`
+- `src/roundtable-planning/components/RecommendAgentsDialog.tsx`
+
+当前 `DraftStep2Snapshot` 结构大致是：
+
+```ts
+export interface DraftStep2Snapshot {
+  selectedAgents?: Array<{ agent_id: string; name: string }>;
+  threadIds: ThreadIdMap | null;
+  coordinatorName: string | null;
+  step2RoundtableDialogues: unknown[];
+  lastLeaderContent: string;
+  hasConsensus: boolean;
+  consensusPercentage: number;
+  budgetLimit: number;
+  seatStubMessages?: Record<string, unknown[]>;
+  orchestrationMode?: "recommend" | "chain";
+  chain?: { id: string; title: string } | null;
+}
+```
+
+这意味着一个草稿只有一份：
+
+- 参会智能体
+- 多智能体 thread 映射
+- 研讨气泡
+- 总控最终内容
+- 共识状态
+- 沙箱产物 stub
+- 编排模式和业务链条
+
+当前 `RoundtablePlanningPage.tsx` 里的 `handleConfirmAgents` 在用户点击「进入研讨」后会：
+
+1. 规范化选中的 agents。
+2. 写入 `step2.selectedAgents`。
+3. 调用 `step2.resetInitGate()`。
+4. 设置 `orchestrationMode` / `chainMeta`。
+5. 切到 `currentStep = 2`。
+
+它没有先把当前 Step2 结果归档成「第一次生成结果」，也没有为新的研讨创建独立 run。因此第二次研讨天然会复用同一个 `draft.step2` 写入位置。
+
+## 目标模型
+
+建议引入 Step2 run 概念：一个草稿可以有多条 Step2 结果线，每条结果线保存一份完整的 Step2 快照。
+
+```ts
+interface Step2RunSnapshot {
+  id: string;
+  title: string;
+  createdAt: string;
+  source: "initial" | "recommend" | "chain" | "manual";
+  selectedAgents?: Array<{ agent_id: string; name: string }>;
+  threadIds: ThreadIdMap | null;
+  coordinatorName: string | null;
+  step2RoundtableDialogues: unknown[];
+  lastLeaderContent: string;
+  hasConsensus: boolean;
+  consensusPercentage: number;
+  budgetLimit: number;
+  seatStubMessages?: Record<string, unknown[]>;
+  orchestrationMode?: "recommend" | "chain";
+  chain?: { id: string; title: string } | null;
+  step3?: DraftStep3Snapshot | null;
+}
+```
+
+`DraftStep2Snapshot` 保留现有字段作为当前激活 run 的镜像，同时新增 `runs` 和 `activeRunId`：
+
+```ts
+export interface DraftStep2Snapshot {
+  activeRunId?: string;
+  runs?: Step2RunSnapshot[];
+
+  selectedAgents?: Array<{ agent_id: string; name: string }>;
+  threadIds: ThreadIdMap | null;
+  coordinatorName: string | null;
+  step2RoundtableDialogues: unknown[];
+  lastLeaderContent: string;
+  hasConsensus: boolean;
+  consensusPercentage: number;
+  budgetLimit: number;
+  seatStubMessages?: Record<string, unknown[]>;
+  orchestrationMode?: "recommend" | "chain";
+  chain?: { id: string; title: string } | null;
+}
+```
+
+这样做的好处：
+
+- 老代码仍然可以从 `draft.step2.step2RoundtableDialogues` 读取当前结果。
+- 新 UI 可以从 `draft.step2.runs` 展示第一次、第二次、第三次生成结果。
+- 老草稿没有 `runs` 时，可以在 hydrate 时把原来的 `step2` 包装成一条默认 run。
+- 暂时不需要改数据库表结构，因为 `step2` 本身就是 JSON 快照。
+
+## 行为设计
+
+### 1. 历史记录加载
+
+用户点击历史记录加载草稿时：
+
+1. 拉取完整草稿。
+2. 如果 `draft.step2.runs` 存在，使用 `activeRunId` 找到当前结果线。
+3. 如果 `draft.step2.runs` 不存在，但旧字段里有 `step2RoundtableDialogues`，自动包装成一条 run：
+
+```ts
+{
+  id: "legacy-run",
+  title: "第一次生成结果",
+  createdAt: draft.updatedAt,
+  source: "initial",
+  ...draft.step2
+}
+```
+
+4. hydrate 当前 active run 到 Step2 runtime。
+5. 左下角展示 run 列表。
+
+### 2. 再次点击智能体推荐进入研讨
+
+用户在已有历史草稿中再次点击「智能体推荐」并确认进入研讨时：
+
+1. 先把当前页面里的 Step2 状态保存为当前 active run。
+2. 创建一条新的 run：
+
+```ts
+{
+  id: crypto.randomUUID(),
+  title: `第 ${runs.length + 1} 次生成结果`,
+  createdAt: new Date().toISOString(),
+  source: result.mode,
+  selectedAgents: normalizedAgents,
+  threadIds: null,
+  coordinatorName: null,
+  step2RoundtableDialogues: [],
+  lastLeaderContent: "",
+  hasConsensus: false,
+  consensusPercentage: 0,
+  budgetLimit: DEFAULT_BUDGET,
+  seatStubMessages: {},
+  orchestrationMode: result.mode,
+  chain: result.mode === "chain" ? result.chain ?? null : null
+}
+```
+
+3. 将 `activeRunId` 切到新 run。
+4. 清空 Step2 runtime。
+5. 设置新选中的 agents / mode / chain。
+6. `resetInitGate()`，进入 Step2 后重新创建一组独立 thread。
+7. 自动保存草稿。
+
+关键点：第二次 run 必须使用新的 `threadIds`，不能沿用第一次 run 的 `threadIds`，否则后端 thread 历史会混在一起。
+
+### 3. 左下角结果列表
+
+左下角建议展示一个「生成结果」区域：
+
+- 第一次生成结果
+- 第二次生成结果
+- 第三次生成结果
+
+每条展示：
+
+- 标题
+- 创建时间
+- 状态：研讨中 / 已达成共识 / 未完成 / 已生成报告
+- 使用模式：智能体推荐 / 业务链条
+
+点击某条结果时：
+
+1. 保存当前 active run。
+2. 切换 `activeRunId`。
+3. hydrate 被点击的 run。
+4. 中间 Step2 对话区显示该 run 的研讨气泡。
+5. 如果该 run 已有 `step3`，进入 Step3 时展示对应报告。
+
+### 4. Step3 结果归属
+
+目前 `draft.step3` 是草稿级别的一份报告。如果只保留这一份，第二次结果生成报告后仍会覆盖第一次报告。
+
+建议：
+
+- `draft.step3` 继续作为当前 active run 的镜像，兼容现有 Step3 页面。
+- 每条 `Step2RunSnapshot.step3` 保存自己的报告。
+- `onReportSaved` 时同时写入当前 active run 的 `step3`。
+
+这样用户切换到第一次生成结果时，可以看到第一次的 Step3 报告；切换到第二次生成结果时，可以看到第二次的 Step3 报告。
+
+## 建议改动点
+
+### 1. `api/drafts.ts`
+
+扩展类型：
+
+- 新增 `Step2RunSnapshot`。
+- `DraftStep2Snapshot` 增加 `activeRunId?: string` 和 `runs?: Step2RunSnapshot[]`。
+
+同时保留旧字段，避免影响现有保存、加载和 Step3。
+
+### 2. `useStep2Orchestration.ts`
+
+新增或暴露两个能力：
+
+- `getCurrentRunSnapshot()`：从当前 Step2 runtime 生成一条 run 快照。
+- `hydrateRunSnapshot(run)`：把某条 run 恢复到 Step2 runtime。
+
+`hydrateFromDraft` 继续存在，但内部可以优先选择 active run 来 hydrate。
+
+### 3. `RoundtablePlanningPage.tsx`
+
+新增页面级状态：
+
+```ts
+const [step2Runs, setStep2Runs] = useState<Step2RunSnapshot[]>([]);
+const [activeStep2RunId, setActiveStep2RunId] = useState<string | null>(null);
+```
+
+调整几个流程：
+
+- `getStep2Snapshot` 输出 `runs` 和 `activeRunId`。
+- `hydrateStep2` 兼容旧草稿并恢复 runs。
+- `handleConfirmAgents` 在新建研讨前先归档当前 active run，再创建新 run。
+- `onReportSaved` 把 Step3 报告写回当前 active run。
+
+### 4. `Step2Panel.tsx`
+
+新增左下角结果列表展示。建议作为一个独立组件，避免 Step2Panel 继续变大：
+
+```tsx
+<Step2RunSwitcher
+  runs={step2Runs}
+  activeRunId={activeStep2RunId}
+  onSelect={handleSelectStep2Run}
+/>
+```
+
+组件职责只做展示和选择，不直接读写 draft。
+
+### 5. `Step3Panel.tsx`
+
+传入当前 active run 的报告：
+
+- 如果当前 run 有 `step3`，展示它。
+- 如果没有，按现有逻辑生成新报告。
+- 生成完成后通过 `onReportSaved` 写回 run。
+
+## 兼容策略
+
+老草稿没有 `runs` 字段时，不做数据迁移，前端加载时即时包装。
+
+判断规则：
+
+```ts
+function normalizeStep2Runs(step2: DraftStep2Snapshot): {
+  runs: Step2RunSnapshot[];
+  activeRunId: string | null;
+} {
+  if (step2.runs?.length) {
+    return {
+      runs: step2.runs,
+      activeRunId: step2.activeRunId ?? step2.runs[0].id,
+    };
+  }
+
+  const hasLegacyContent =
+    step2.step2RoundtableDialogues?.length > 0 ||
+    Boolean(step2.threadIds) ||
+    Boolean(step2.lastLeaderContent);
+
+  if (!hasLegacyContent) {
+    return { runs: [], activeRunId: null };
+  }
+
+  const legacyRun: Step2RunSnapshot = {
+    id: "legacy-run",
+    title: "第一次生成结果",
+    createdAt: new Date().toISOString(),
+    source: step2.orchestrationMode ?? "initial",
+    selectedAgents: step2.selectedAgents,
+    threadIds: step2.threadIds,
+    coordinatorName: step2.coordinatorName,
+    step2RoundtableDialogues: step2.step2RoundtableDialogues,
+    lastLeaderContent: step2.lastLeaderContent,
+    hasConsensus: step2.hasConsensus,
+    consensusPercentage: step2.consensusPercentage,
+    budgetLimit: step2.budgetLimit,
+    seatStubMessages: step2.seatStubMessages,
+    orchestrationMode: step2.orchestrationMode,
+    chain: step2.chain,
+  };
+
+  return { runs: [legacyRun], activeRunId: legacyRun.id };
+}
+```
+
+## 风险点
+
+### 1. 自动保存覆盖
+
+Step2 现在会在每个气泡收尾时自动保存。如果引入多 run，自动保存必须先把当前 runtime 合并回 active run，再写入 `draft.step2.runs`。
+
+否则会出现 UI 切到第二次结果，但保存时仍更新第一次 run 的情况。
+
+### 2. threadIds 混用
+
+每条 run 必须拥有自己的 `threadIds`。新建 run 时要清空 `threadIds` 并让 Step2 重新 init。
+
+如果复用旧 thread，会导致两次研讨的后端上下文互相污染。
+
+### 3. Step3 报告覆盖
+
+如果只保存草稿级 `step3`，多 run 的报告无法分别查看。
+
+建议把报告写入当前 run，同时保留草稿级 `step3` 作为 active run 镜像。
+
+### 4. 正在运行中的 run
+
+如果配合后台任务能力，run 还需要带 job 信息：
+
+```ts
+jobId?: string | null;
+jobStatus?: JobStatus | null;
+```
+
+这样左下角可以显示「第二次生成结果正在运行」，并打开派活链路弹窗。
+
+## 分阶段实现建议
+
+### P0：纯前端多 run 快照
+
+目标：先解决“第一次 / 第二次结果分别可查看”。
+
+- 扩展 `DraftStep2Snapshot` 类型。
+- 页面维护 `step2Runs` / `activeStep2RunId`。
+- `handleConfirmAgents` 新建 run。
+- 左下角展示 run 列表。
+- 切换 run 能恢复不同 Step2 对话。
+
+不改后端表结构。
+
+### P1：Step3 绑定 run
+
+目标：每次研讨结果对应自己的报告。
+
+- `Step2RunSnapshot.step3` 保存报告。
+- `onReportSaved` 写回 active run。
+- 切换 run 时同步 Step3 显示。
+
+### P2：后台任务绑定 run
+
+目标：和后台挂起执行方案打通。
+
+- run 增加 `jobId` / `jobStatus`。
+- 历史列表和左下角都能显示某条 run 正在执行。
+- 点击正在执行的 run 打开派活链路弹窗。
+
+### P3：后端 run 表
+
+如果后续一个草稿下 run 数量很多，或者需要服务端按 run 查询、删除、重命名，再考虑新增后端表：
+
+- `roundtable_runs`
+- `draft_id`
+- `run_id`
+- `title`
+- `status`
+- `step2_snapshot`
+- `step3_snapshot`
+- `created_at`
+- `updated_at`
+
+短期不建议一开始就上表，先用现有 `step2` JSON 快照落地更快。
+
+## 验收清单
+
+- 从历史记录加载旧草稿时，左下角出现「第一次生成结果」。
+- 点击「第一次生成结果」能看到原来的 Step2 研讨气泡。
+- 在历史草稿中重新点击「智能体推荐」并「进入研讨」后，左下角新增「第二次生成结果」。
+- 第二次研讨开始时，Step2 对话区为空或只显示新 run 初始化内容。
+- 第二次 run 使用新的 `threadIds`，不会复用第一次 run 的后端线程。
+- 切回「第一次生成结果」时，第一次的对话、共识状态、沙箱产物仍可查看。
+- 切回「第二次生成结果」时，第二次的对话继续显示。
+- 刷新页面后再次加载该历史草稿，两条结果线都还在。
+- 如果两次都生成了 Step3 报告，切换不同结果线时能看到各自对应的报告。

+
+## 0. 背景与目标
+
+### 0.1 现状
+
+Step 2 圆桌目前有两种编排模式（`orchestrationMode`，见 `hooks/useStep2Orchestration.ts`）：
+
+- **`free`（自由模式）**：总控（leader）自由决定派活给谁，`runOrchestration` 循环驱动。
+- **`chain`（线性链条）**：用户把席位排成一条**线性**链 `A → B → C`，`runChainOrchestration` 按顺序逐个派活，最后总控收口。链路用 `DispatchChainModal.tsx` 的**横向流程图**展示（总控 → 席位1 → 席位2 → … → 共识 → 报告）。
+
+链条数据现在只是一个**有序数组** `selectedAgents`（线性），节点状态类型见 `lib/job-types.ts`（`ChainNodeState = pending | active | done`）。
+
+### 0.2 目标（本次新增）
+
+1. **DAG 编排**：用户可视化指定**智能体之间的直接依赖关系**——有的串行（`A → B → C`），有的并行（`A B C` 同时跑）。编排结果是一张**流程图（DAG）**。
+2. **并行执行**：DAG 里同一层（互不依赖）的智能体**并行**跑，墙钟时间从「串行求和」降到「并行取最慢」。
+3. **并行禁止写文件**：并行的智能体**禁用文件写入 / 沙箱命令**，避免它们同时打开沙箱互相打架。产物以消息正文交付；落文件留给串行 / 收口阶段。
+4. **并行高性能显示**：并行时收起左侧、顶部头像条切换、主区同时显示 2 个智能体的消息流，其余**只接流不渲染**，避免页面卡死。
+
+### 0.3 设计总原则
+
+- **复用** 现有 special run / leader run / rollback 抢占 / 轻量交付状态接口（`GET /threads/{id}/last-ai-message`），不另起炉灶。
+- **线性链是 DAG 的特例**：`chain` 模式可平滑迁移成"每层 1 个节点"的 DAG，老数据不破坏。
+- **分层（Stage）优先于自由连线**：编辑交互首选「分层」模型（每个 stage 放若干并行席位，stage 间串行），实现成本低、覆盖 95% 的"串 / 并"诉求；自由连线画布作为后续可选增强（见 §2.3）。
+
+### 0.4 已确认的设计决策（✅ 本期按这些实现）
+
+> 以下三项已与需求方确认锁定，实现时直接按此，不再二选一。
+
+1. **✅ 编排模型 = 分层 Stage**：本期只做分层（每个 stage 放若干并行席位、stage 间串行）。**自由连线画布本期不做**，仅在数据模型层预留（§1.2）以免将来返工。
+2. **✅ 并行跳过 leader、前端直派**：DAG 由用户显式指定，执行时前端**直接**对 stage 内席位发起 special run，**不**每个 stage 再跑一轮总控派活；只在最后 `finalSynthesis` 跑一轮 leader 综合（即 §3.2 的方案 B）。
+3. **✅ 主区固定 2 列，窄屏降 1 列**：并行时主区最多并排显示 2 个被选中智能体的消息流；窄屏（断点见 §5.3）降为 1 列 + 头像条横向滚动。不做 3+ 列。
+
+---
+
+## 1. 数据模型
+
+### 1.1 DAG 的「分层」表示（推荐，主模型）
+
+把 DAG 表示成**有序的 stage 列表**，每个 stage 内的席位并行、stage 之间串行：
+
+```ts
+// lib/dag-types.ts （新建）
+
+/** 一个并行批次：stage 内所有席位并行执行。 */
+export interface OrchestrationStage {
+  /** stage 稳定 id（拖拽重排 / diff 用）。 */
+  id: string;
+  /** 本 stage 并行执行的席位（agent_id 列表）。1 个 = 退化为串行节点。 */
+  agentIds: string[];
+}
+
+/** 用户编排出的执行计划。stages 顺序即串行顺序。 */
+export interface OrchestrationPlan {
+  /** 编排模式标识，持久化进 step2。 */
+  mode: "dag";
+  /** 串行执行的批次；每批内并行。 */
+  stages: OrchestrationStage[];
+  /** 收口：是否在所有 stage 完成后由总控综合（默认 true）。 */
+  finalSynthesis: boolean;
+}
+```
+
+- **串行** `A → B → C` = `stages: [{agentIds:[A]}, {agentIds:[B]}, {agentIds:[C]}]`。
+- **并行** `A B C` = `stages: [{agentIds:[A,B,C]}]`。
+- **混合** `A →(B C)→ D` = `stages: [{[A]}, {[B,C]}, {[D]}]`。
+
+> 为什么用分层而不是「邻接表 / 边」：执行调度本就是「拓扑分批」，分层就是分批的结果，前端不必再做拓扑排序，也天然避免环；编辑器交互更直观（拖卡片进 stage）。真正的自由连线 DAG 见 §2.3（可选）。
+
+### 1.2 通用 DAG 表示（§2.3 自由连线时才需要）
+
+若将来做自由连线画布，再引入边表示，并在执行前做一次**拓扑排序 → 分层**，落回 §1.1 的 stages 结构给调度器用：
+
+```ts
+export interface DagEdge { from: string; to: string }   // from 完成后才能跑 to
+export interface DagGraph { nodes: string[]; edges: DagEdge[] }
+// 执行前：toposortToStages(graph) -> OrchestrationStage[]
+```
+
+### 1.3 持久化
+
+- 复用 `roundtable_drafts.step2` JSON（见后端 `app.gateway.routers` roundtable-drafts + `hooks/useStep2Orchestration.ts` 里对 `step2` 的读写）。
+- 在 `step2` 增加字段：`orchestrationPlan: OrchestrationPlan | null`。
+- `orchestrationMode` 扩展为 `"free" | "chain" | "dag"`；`chain` 旧数据读取时即时转换为单节点-stage 的 `dag`（兼容层，不改老 draft）。
+
+### 1.4 校验（纯函数，可单测）
+
+`lib/dag-types.ts` 内提供：
+
+```ts
+validatePlan(plan: OrchestrationPlan, selectedAgentIds: string[]): {
+  ok: boolean;
+  errors: string[];   // 面向用户的中文提示
+}
+```
+
+校验项：
+- 每个 `agentId` 必须在本次选定席位 `selectedAgents` 内（防止编排了不存在的席位 → 复用后端 `_partition_dispatch` 同思路的"必须在 roster 内"）。
+- 不允许空 stage；不允许同一席位出现在多个 stage（一个席位只跑一次）。
+- 至少 1 个 stage。
+- （可选）单 stage 并行度上限提示（如 > 6 并行给 warning：远程模型并发 + 沙箱压力）。
+
+---
+
+## 2. 编排编辑器（流程图构建）交互
+
+### 2.1 入口与整体布局
+
+- 在 Step 2 顶部模式切换里新增 **「依赖编排」**（`dag`）模式（与现有 自由 / 链条 并列）。
+- 选择 `dag` 后弹出 / 进入**编排编辑器**（复用 Dialog 大弹窗，参考 `DispatchChainModal` 的尺寸 `w-[94vw] max-w-[1240px]`）。
+
+### 2.2 推荐交互：分层（Stage）编辑器（Phase 2 实现）
+
+```
+┌ 依赖编排 ───────────────────────────────────────── [校验✓] [保存] ┐
+│  可选席位（点/拖加入某个 stage）                                   │
+│  [情报收集] [环境评估] [方案设计] [风险审查] [执行规划] [前端实现]  │
+│ ─────────────────────────────────────────────────────────────── │
+│  Stage 1（并行）              Stage 2（并行）       Stage 3        │
+│  ┌──────────┐  ─────▶  ┌──────────┐ ┌────────┐ ─▶ ┌──────────┐    │
+│  │ 情报收集 │          │ 方案设计 │ │风险审查│    │ 执行规划 │    │

+│   [＋ 拖席位到此]        [＋]                       [＋]            │
+│  [＋ 新建 Stage（串在最后）]                                       │
+│ ─────────────────────────────────────────────────────────────── │
+│  说明：同一 Stage 内的席位会**并行**执行；Stage 之间**串行**       │
+│  （后一个 Stage 能看到前面所有 Stage 的交付摘要）。                │
+└───────────────────────────────────────────────────────────────────┘
+```
+
+交互要点：
+- **加入 stage**：从顶部可选席位**拖拽**到某个 stage，或点席位 →「加入 Stage N」。
+- **移动 / 重排**：席位可在 stage 间拖动；stage 可整体左右拖动重排（改串行顺序）。
+- **删除**：席位 / 空 stage 可删。
+- **并行度提示**：stage 内 ≥2 席位即标「并行」徽标；过多给 warning。
+- **实时校验**：`validatePlan` 实时跑，错误在顶部红条提示，「保存」在校验通过前禁用。
+- **预览流程图**：编辑区下方实时渲染只读流程图缩略（复用 §7 的 DAG 流程图组件）。
+
+> 拖拽可用现成轻量方案（HTML5 DnD 或 `@dnd-kit`，看项目是否已有依赖；没有就先用「点选 + 加入/移出按钮」的无拖拽版，Phase 2 先上无拖拽、Phase 2.5 再加拖拽）。
+
+### 2.3 可选增强：自由连线画布（后续，非本期必须）
+
+- 节点自由摆放 + 拉线建边 → `DagGraph`（§1.2）。
+- 实现成本高（画布 / 连线 / 命中检测 / 自动布局），且分层模型已覆盖绝大多数诉求。**本期不做**，仅在数据模型上预留 §1.2，避免将来返工。
+
+### 2.4 验收（Phase 2）
+
+- 能拖 / 点把席位分配到多个 stage，保存进 `step2.orchestrationPlan`。
+- 刷新 / 重进 draft 能恢复编排。
+- 非法编排（空 stage / 席位重复 / 席位不在 roster）有明确中文提示且无法保存。
+
+---
+
+## 3. 执行调度（前端编排循环 + 后端复用）
+
+### 3.1 新增 `runDagOrchestration`（`useStep2Orchestration.ts`）
+
+与现有 `runOrchestration` / `runChainOrchestration` 并列，逻辑：
+
+```
+for (stageIndex, stage of plan.stages):
+  if isStale() break               // 复用现有 epoch 抢占（人工干预/暂停）
+  // 1) 总控按本 stage 的席位并行派活（一轮 leader，dispatched = stage.agentIds）
+  //    —— 或跳过 leader，前端直接对 stage 内每个席位发起 special run（见 3.2）
+  // 2) 并行跑 stage 内所有席位
+  await Promise.all(stage.agentIds.map(seat =>
+        streamMultiAgent({ agentType:"special", agentName:seat,
+                           newMessage: buildStageTask(seat, plan, stageIndex),
+                           parallelNoFile: stage.agentIds.length > 1,  // §4
+                           ... })))
+  // 3) 等本 stage 全部 ✅（Promise.all 天然 barrier）再进入下一 stage
+// 4) finalSynthesis：最后一轮 leader（synthesisMode=true）综合所有 stage 交付
+```
+
+要点：
+- **批内并行**：`Promise.all`（不是现在的 `for await` 串行）。
+- **批间串行**：`Promise.all` 即 barrier，自动等齐。
+- **依赖可见性**：进入 stage N 的席位时，把**前面所有 stage 已交付席位的摘要**拼进它的 `newMessage`（复用 §交付状态：网关 `_collect_delivery_status` / `GET last-ai-message?max_chars=N`，前端也可在 stage 边界拉一次摘要拼进 task）。这样 `(B C)` 能看到 `A` 的产出。
+- **抢占 / 干预 / 暂停**：每个 stage 边界检查 `isStale()`（epoch），与现有自由 / 链条模式一致。
+- **rollback**：special run 已统一 `multitask_strategy=rollback`，并行多席位各自不同 thread，互不冲突。
+
+### 3.2 是否每 stage 都走 leader？ — ✅ 已定：前端直派（方案 B）
+
+**本期采用方案 B**：DAG 由用户**显式**指定，不需要 leader 再"决定派给谁"。前端**直接**对 stage 内每个席位发起 special run，省掉每 stage 的 leader LLM 往返（更快、更可控）；只在所有 stage 完成后、`finalSynthesis` 为真时跑**一轮** leader（`synthesisMode=true`）综合所有交付。
+
+> （备选方案 A：每 stage 跑一轮 leader 派活——更贴现有架构但每 stage 多一次 leader LLM、更慢。**本期不采用**，留档备查。）
+
+### 3.3 后端改动
+
+- **基本不需要新接口**：special run（`POST /api/multi-agent/run/stream` agent_type=special）、leader run、轻量交付读（`GET /threads/{id}/last-ai-message`）、轻量追加（`POST /threads/{id}/messages/append`）都已就绪。
+- 仅需 §4 的「并行禁写文件」run policy 开关。
+
+### 3.4 验收（Phase 3）
+
+- `(B C)` 两席位**同时**出现在执行（后端日志两条 special run 时间重叠；前端两个流并行增长）。
+- stage 间严格串行（stage 2 不早于 stage 1 全部完成）。
+- stage N 席位的输入里能看到 stage <N 的交付摘要。
+
+---
+
+## 4. 并行时禁止写文件（防沙箱打架）
+
+### 4.1 后端 run policy
+
+`app/gateway/roundtable_run_policy.py` 现有角色：`leader` / `seat` / `report`。新增一个角色或开关：
+
+- 方案：给 `seat` 增加一个「并行变体」`seat_parallel`，其 `excluded_tools` 在 `seat` 基础上**再禁** `write_file` / `bash` / `str_replace` / `present_files`（与 `report` 角色禁写的思路一致）。
+- `_special_run`（`multi_agent.py`）按请求里的一个新 flag（如 `no_file: true`）选择 `seat_parallel` policy。
+
+### 4.2 前端传参
+
+- `streamMultiAgent` 请求体新增 `parallel_no_file?: boolean`（或复用 `no_file`）。
+- `runDagOrchestration` 在 `stage.agentIds.length > 1`（真并行）时置 `true`；单节点 stage（实际串行）不限制，可正常写文件。
+
+### 4.3 产物归属
+
+- 并行席位的产物 = **消息正文**（被 `_collect_delivery_status` / 综合块读取）。
+- 需要落文件 / 画图的（如 Step3 报告、`roundtable-report`）放在**串行的收口阶段**单独跑，不在并行批次里。
+
+### 4.4 验收（Phase 4）
+
+- 并行 stage 的席位 run 日志显示 `Excluded ... ['write_file','bash','str_replace','present_files', ...]`。
+- 并行期间不再出现多个席位抢同一沙箱 / 写文件冲突。
+
+---

+（左侧"参与角色"栏在并行时整体收起，腾出横向空间放两列消息）
+```
+
+### 5.2 关键交互（与需求逐条对齐）
+
+1. **收起左侧**：并行执行时把左侧「参与角色 / 人工参与」栏整体折叠（一个 `isParallelRunning` 状态控制；非并行恢复）。
+2. **头像条**：位置在**消息列表上方、模型选择器左侧**。展示**当前并行批次的所有进行中智能体头像**：
+   - **进行中** → 头像加 loading 动画（复用 `DispatchChainModal` 的 `animate-ping` 光环 + `Loader2Icon animate-spin` 角标）。
+   - **已完成** → 打勾（复用现有 `CheckIcon` 角标）。
+   - **选中** → 高亮描边（当前正在主区显示的那 2 个）。
+3. **主区同时显示 2 个**：被选中的 2 个智能体的消息列表**并排两列**渲染。
+4. **多于 2 个先隐藏**：未选中的智能体**不渲染 DOM**（见 §6 性能）。
+5. **点头像切换**：点击未选中的头像 → 把它设为选中之一（替换当前 2 个里的一个，或按"最近点击保留 2 个"的 LRU 策略）；被换下的智能体**停止渲染但继续接流**。
+
+### 5.3 选中策略 — ✅ 固定 2 列，窄屏降 1 列
+
+- 维护 `selectedParallelSeats: string[]`，**最多 2**（固定 2 列）。**不做 3+ 列**。
+- **响应式**：宽屏 2 列并排；窄屏（建议断点 `< 1024px` / `lg`）降为**1 列**，头像条横向滚动切换；此时 `selectedParallelSeats` 仍可存 2 个，但主区只渲染当前 1 个（点头像切换哪个在前）。
+- 默认选中本批次**最先开始**的（宽屏 2 个 / 窄屏 1 个）。
+- 点头像：若已选中则取消；未选中则加入（超过上限时按 LRU 踢掉最早选中的）。被换下的席位**停止渲染但继续接流**（§6）。
+
+### 5.4 验收（Phase 5）
+
+- 并行时左侧收起、出现头像条、主区两列。
+- 进行中头像有 loading；完成打勾；选中有高亮。
+- 点头像能切换主区显示的智能体，且切换是**即时**的（数据已在内存，见 §6）。
+
+---
+
+## 6. 流式高性能策略（避免页面卡死）
+
+> 核心矛盾：N 个并行席位同时高频 `onTextDelta`，若都 setState + Markdown 渲染会卡死。
+
+### 6.1 全接收、惰性渲染
+
+- **所有**并行 run 的流都正常订阅（不丢数据）：每个席位的增量文本**累积进 store / ref**（`Map<agentId, { text, status, charCount }>`）。
+- **只有被选中（主区显示）的席位**才把累积文本挂到 DOM 渲染（Markdown）。
+- **未选中**席位：只更新内存 + 头像条上的轻量进度（字数 / loading），**不挂载消息 DOM**。
+- 切换选中时：把该席位已累积的全文一次性渲染 + 继续接增量。
+
+### 6.2 渲染节流
+
+- 选中席位的流式渲染**节流/合帧**：用 `requestAnimationFrame` 或 ~50–100ms 批量 flush 累积的 token，而不是每个 token 一次 setState。
+- Markdown 渲染对"流式中"可降级（纯文本 / 轻量渲染），**完成后**再做完整 Markdown（现有 `MessageBubble` 的 `streaming` 标志可复用：streaming 时简渲、done 后全渲）。
+
+### 6.3 头像条进度
+
+- 头像条只显示**廉价**信息：loading 动画 + 可选字数（`charCount`，从内存 Map 取，节流更新，例如每 500ms 刷一次）。不触发消息体渲染。
+
+### 6.4 数据流（建议结构）
+
+```
+streamMultiAgent(seat).onTextDelta(text) →
+    parallelStore.append(seatId, text)          // 纯内存累积，O(1)
+    if seatId ∈ selectedParallelSeats:          // 仅选中的进 React state（节流）
+        scheduleFlush(seatId)                    // rAF / 节流 setState
+    else:
+        bumpCharCount(seatId)                    // 仅更新头像条进度（节流）
+```
+
+### 6.5 验收（Phase 6）
+
+- 6+ 席位并行时页面不卡（输入 / 滚动 / 切换流畅）。
+- 切到一个之前隐藏的席位，能立刻看到它**到目前为止的全部**输出（证明流没丢、只是没渲染）。
+
+---
+
+## 7. 流程图执行态可视化（DAG 版）
+
+- 把现有 `DispatchChainModal.tsx`（横向**线性**流程图）扩展 / 复刻成 **DAG 流程图**：
+  - 按 stage 分**列**，stage 内席位**纵向并列**，stage 间用连接线。
+  - 节点状态复用 `ChainNodeState`（pending / active / done）+ 现有动画（`animate-ping` / `Loader2Icon` / `CheckIcon`）。
+  - 末尾接 `共识 → 结果绘制` 里程碑（沿用现有）。
+- 用途：编辑器里的只读预览（§2.2 底部）+ 执行时的总览（可选小窗 / 顶部缩略）。
+
+```
+总控 ─▶ ┌ Stage1 ┐ ─▶ ┌ Stage2 ┐ ─▶ ┌ Stage3 ┐ ─▶ 🤝共识 ─▶ 📊报告
+        │ 情报●  │     │ 方案✓  │     │ 执行○  │
+        └────────┘     │ 风险●  │     └────────┘
+                       └────────┘
+```
+
+### 7.1 验收（Phase 7）
+
+- 编辑器底部 / 执行时能看到 DAG 流程图，节点状态随执行实时更新（active/done）。
+
+### 7.2 实施结论（2026-06-07，✅ 已完成）
+
+- **新组件** `components/DagFlowChart.tsx`：纯展示组件，复刻 `DispatchChainModal` 的节点 / 连线 / 里程碑视觉（`animate-ping` 光环 + `Loader2Icon` 转圈 + `CheckIcon` 打勾 + `rt-chain-connector` 连线动画），但按 **stage 分列**：总控 ─▶ ┌Stage1┐ ─▶ ┌Stage2┐ ─▶ 🤝共识 ─▶ 📊结果绘制，stage 内席位**纵向并列**。`compact` 紧凑模式给缩略图用。所有状态由 props 传入（`stages` / `resolveSeat` / `seatStates` / `coordinatorState` / `consensusState` / `reportState`）；不传 `seatStates` → 全 pending（只读预览）。`aggregateStageState` 把 stage 内席位聚合成列状态(任一 active→active、全 done→done)驱动 stage 间连线。
+- **编辑器只读预览**（§2.2 底部）：`BusinessChainEditorPage` 底部加「编排预览」section，把 `stageGroups`(去空 stage) 映射成 `DagFlowChart` 的 stages + `resolvePreviewSeat`(席位名/配色)，`compact`、全 pending、随编辑实时变。
+- **执行态总览**（Step 2 顶部缩略）：`useStep2Orchestration` 新增 `dagNodeStates: Record<agentId, ChainNodeState>`，`runDagOrchestration` 跨 stage 维护(进入 stage→该批 active、席位终态→done、`resetStep2State` 清空)；经 `RoundtablePlanningPage` 把 `orchestrationMode/orchestrationPlan/dagNodeStates` 传到 `Step2Panel`，dag 模式下会话区顶部 `compact` 渲染 DagFlowChart。总控/共识里程碑状态由 `Step2Panel` 从节点状态 + `isOrchestrating`/`hasConsensus` 派生（中转轮时无席位 active + isOrchestrating → 总控 active）。
+- 改动文件：`components/DagFlowChart.tsx`(新)、`pages/BusinessChainEditorPage.tsx`、`hooks/useStep2Orchestration.ts`、`components/Step2Panel.tsx`、`pages/RoundtablePlanningPage.tsx`。typecheck 零新增(基线 65)。
+- **下次实地验收**：①编辑器底部随分层编辑实时画出流程图;②Step2 dag 模式顶部出现缩略流程图,跑起来后当前 stage 列点亮(active 转圈)、完成打勾、中转时总控亮、最后共识亮。

+## 8. 分步实现计划（每步可独立交付 + 验收）
+
+| Phase | 内容 | 主要文件 | 依赖 | 可独立验收 |
+|---|---|---|---|---|
+| **1** | DAG 数据模型 + 校验 + 持久化字段 | `lib/dag-types.ts`（新）、draft step2 读写 | — | 纯函数单测：`validatePlan` / `chain→dag` 兼容转换 |
+| **2** | 分层编排编辑器（先无拖拽：点选加入/移出） | `components/DagPlanEditor.tsx`（新）、Step2 模式切换 | P1 | 能编排并保存/恢复，非法编排有提示 |
+| **2.5** | 编辑器拖拽 | 同上 + `@dnd-kit`（若引入） | P2 | 拖拽分配/重排 |
+| **3** | `runDagOrchestration`：批内并行 + 批间串行 + 依赖摘要注入 | `hooks/useStep2Orchestration.ts`、`api/multi-agent.ts` | P1 | 后端日志并行 special run 时间重叠；stage 严格串行 |

+
+---
+
+## 9. 边界与异常（Phase 8）
+
+- **某并行节点失败 / 超时**：单个席位失败不拖垮整 stage；标该节点 error，stage 其余 ✅ 仍推进；收口时把"X 失败"如实告知总控（复用交付状态 ⬜ + 失败标记）。
+- **依赖未满足**：调度器保证 stage 串行，理论不会发生；防御性校验 stage N 启动前 stage <N 必须全部终态（done/failed）。
+- **人工干预 / 暂停 / 恢复**：在 stage 边界检查 `isStale()`（epoch）；干预指令插入后，从"下一个未开始的 stage"继续（已完成 stage 不重跑）。
+- **并行禁写文件 vs 席位本想写文件**：在席位 SOUL / 派活提示里说明"本轮为并行研讨，产出请直接写在回复正文，不要写文件"，降低模型困惑。
+- **窄屏**：主区两列降为一列 + 头像条横向滚动。
+- **单 stage 全并行（一次性 N 个）**：给并行度 warning（远程模型并发限流 / 成本）。
+
+---
+
+## 10. 与现有代码的衔接点速查
+
+- 编排循环：`hooks/useStep2Orchestration.ts`（`runOrchestration` / `runChainOrchestration` 旁新增 `runDagOrchestration`；复用 `isStale()` epoch、`abortAllInFlight`、`appendStreamingDialogue` / `appendToDialogue`）。
+- 流式 API：`api/multi-agent.ts`（`streamMultiAgent`，新增 `parallel_no_file` 入参；`onTextDelta(text, messageId)` 已是按席位回调，天然支持并行分流）。
+- 显示：`components/Step2Panel.tsx`（消息列表 `step2RoundtableDialogues.map`；新增头像条 `ParallelSeatStrip` + 两列容器 + 折叠左侧）。
+- 流程图：`components/DispatchChainModal.tsx` / `lib/job-types.ts` / `lib/business-chain.ts`（复刻成 DAG 版）。
+- 常量 / 元数据：`lib/roundtable-constants.ts`（`BUILTIN_AGENT_META` 头像/中文名、`buildAgentNameToRole`）。
+- 后端 run policy：`app/gateway/roundtable_run_policy.py`（新增 `seat_parallel`）、`app/gateway/routers/multi_agent.py`（`_special_run` 读 `no_file` flag）。
+- 交付摘要：`GET /api/threads/{id}/last-ai-message?max_chars=N`（依赖注入 stage N 输入用）。
+
+---
+
+## 11. 一句话总结
+
+把「线性链条」升级为「分层 DAG」：**编辑器**用分层 stage（拖卡片）表达串/并；**调度**用 `Promise.all` 批内并行、批间 barrier 串行，依赖摘要在 stage 边界注入；**并行禁写文件**避免沙箱打架；**显示**收起左侧、头像条切换、主区两列、未选中只接流不渲染（rAF 节流）保证不卡。全部建立在现有 special/leader run + 轻量交付接口之上，后端几乎零新接口。
+
+---
+
+## 12. 已知问题与排查记录（2026-06-06）
+
+### 12.1 ❗并行席位「步骤条」不显示 —— 根因：`seat_parallel` 工具面禁得过多
+
+**现象**：并行两列里的席位气泡看不到步骤条（`MessageStepsCard`），而串行席位有。
+
+**排查结论（已定位，待修）**：
+
+1. **步骤条只渲染「工具调用」步骤**。`MessageStepsCard` 的 `isToolStep` 只认 `tool_calling:<toolName>` 的步骤进折叠卡；纯阶段步骤（`connecting:` / `streaming:` 这类 reasoning）只渲染成**底部一行小灯泡**，不出大卡（见 `MessageStepsCard.tsx` L80-100）。
+2. **并行席位几乎调不动任何会产生步骤的工具**。后端 `app/gateway/roundtable_run_policy.py`：
+   - `_SEAT_EXCLUDED = [web_search, ask_clarification, present_files, view_image, agent_orchestration]` —— **注意 `web_search` 对所有席位（串行也）就禁了**（注释「圆桌研讨里联网搜索一律禁用」）。
+   - `_SEAT_PARALLEL_EXCLUDED = _SEAT_EXCLUDED + [write_file, bash, str_replace]`。
+   - 于是并行席位可用工具几乎只剩 `read_file / ls / task / write_todos / memory / hindsight_*`，研究/分析类席位基本一个都不会调 → **没有任何 `tool_calling` 步骤** → 步骤条（大卡）不出现。
+3. **对比串行为何「有步骤条」**：串行席位（`seat` policy）**能 `write_file`**，会产生 `tool_calling:write_file` 步骤 → 大卡出现。并行被禁了 write_file + 又没有 search，所以一个工具步都没有。
+
+**用户诉求**：并行时**只禁真正会冲突的写操作**，搜索信息 / 调用技能等**必要操作不要禁**。
+
+**关键事实（影响方案选择）**：圆桌每个席位是**独立 thread = 独立 sandbox**（后端 per-thread 隔离 `.deer-flow/users/{uid}/threads/{tid}/`）。所以并行席位写文件**在后端并不会互相冲突**；当初 §4「并行禁写文件」的「打架」其实主要是**前端单沙箱预览**（`activeArtifactThreadId` 只能同时显示一个）+ 产物归集到正文的简化考量，并非后端真冲突。→ 这意味着「并行禁写」的必要性比原设想弱，可放宽。
+
+**✅ 决策：选 A（2026-06-06 已实施）**：把 `seat_parallel` 放宽到**只禁 `write_file / bash / str_replace`**（防前端单沙箱预览串台 + 产物走正文）+ 仍禁 `ask_clarification / present_files / view_image / agent_orchestration`（打断/越权类），但**放开 `web_search` 与技能**（搜索不碰 sandbox；技能靠 `read_file`）。改在 `app/gateway/roundtable_run_policy.py` 的 `_SEAT_PARALLEL_EXCLUDED`（**不再继承** seat 的 web_search 禁用，显式列举），测试 `tests/test_roundtable_run_policy.py` 同步更新（`test_seat_parallel_allows_web_search_and_skills`）。
+→ 并行席位现在能联网搜索/用技能 → 产生 `tool_calling` 步骤 → 步骤条显示。
+
+> 备选 B（连写文件也放开，沙箱按 thread 隔离）/ C（重新评估「圆桌串行也一律禁 web_search」）**本期不做**，留档。串行席位目前仍禁搜索（`seat` policy 不变）。
+
+### 12.2 其它已修（本轮反馈）
+
+- 最左侧**全局工作区侧栏**并行时收起：改用与「打开沙箱」同一路径 `useSidebarSafe()?.setOpen(false)`（之前只收了圆桌「参与角色」栏 `step2SidebarExpanded`）。并行结束**不自动展开**（与沙箱收起不回弹一致）。
+- 并行两列改回**完整 Markdown**（撤销 §6.2 流式纯文本降级 `plainWhileStreaming`），与串行同款 `Step2Message`。
+- 头像条**不再显示字数**（去掉 charCount 徽标 + 字段）。
+- **致命 bug 已修**：用户干预 / 并行跑完后**不再重跑整张 DAG**。`dagPlanExecutedRef` 闸门 + DAG 各阶段跑完后释放锁 `await runOrchestration(handoff)` 交回总控继续派活/收口；后续干预/恢复一律走 leader 自由派活。
+- **并行两列宽表溢出已修（2026-06-07）**：模型输出的 Markdown **表格**（如「法律免责条款」表）没有宽度约束 / 横向滚动容器，在并行两列的窄列里会**超出左列、盖到相邻列**。修法：`MessageBubble.sharedMarkdownComponents.table`（+ `markdown-components.tsx`）把 `<table>` 套进 `<div class="max-w-full overflow-x-auto">`——表格保持自然宽度、超出时**列内横向滚动**而非撑破列宽。`min-w-0` 链(grid `minmax(0,1fr)` → 列 `min-w-0` → 气泡 `flex-1 min-w-0`)本就齐全,只差 table 这一层。
+- **关于「并行席位无步骤条」**：步骤条(`MessageStepsCard` 大卡)只在席位产生 `tool_calling` 步骤时出现(§12.1)。纯分析型席位若本轮**直接写分析正文、没调用任何工具**(web_search 等),就只显示一行「正在输出」思考指示、不出大卡——这是设计使然,非解析失败。要确认是否真调了工具:浏览器 devtools 设 `window.__MULTI_AGENT_DEBUG__=true` 看 `frame# event=messages` 里有无 tool_calls,或查后端 special run 日志。
+
+### 12.3 ✅需求变更：Stage 间「经总控中转 + 广播」（2026-06-06 提出，2026-06-07 已实施）
+
+**当前实现（方案 B，§3.2）**：DAG 各 stage 由前端**直接**派活，stage 间不跑 leader，靠前端把 `buildDependencySummary` 拼进下一 stage 的 task（`priorSummary`）。各 stage 跑完后才 `await runOrchestration` 交回总控收口。
+
+**新诉求**：业务链条调用时，**每一轮 stage 之间都要经总控中转 + 广播**，而不是前端直接串下去。具体：
+
+1. 第 1 轮并行调用 stage1 的 A、B、C；
+2. A/B/C **全部完成后**，把这一批的**输出广播出来**（广播给其它席位 + 总控 thread）；
+3. **总控（leader）接收**这批交付 → 再**往下继续派活**（派 stage2 的 D、E）；
+4. 派活时把（承上的）消息**广播给下一轮的 D、E**；
+5. 以此类推，直到所有 stage 跑完再收口。
+
+> 即把 §3.2 的「方案 B 前端直派」改成 **「方案 A' = 计划约束下的总控中转」**：stage 边界插入一轮 leader，由它综合上一批交付并驱动下一批（下一批席位仍由编排计划**钉死**为 D、E，不是 leader 自由乱派——leader 负责「承上启下 + 广播上下文」，计划负责「派给谁」）。
+
+**实施要点（下次会话）**：
+
+- **每个 stage 完成 → 广播该批输出**：后端 `_special_run` 已对每个 seat 做 detached 后广播（「子智能体X完成…交付内容为:…」→ 其它席位 + 总控）。但它是 **detached/best-effort + 截断**；要让总控**可靠**地在下一轮前看到，需在 stage barrier 处**等广播落地**（或前端在 stage 边界用 `GET /threads/{id}/last-ai-message` 主动收齐各席位交付再喂给 leader）。
+- **插入 leader 中转轮**：`runDagOrchestration` 在进入下一 stage 前，跑一轮 leader（`synthesisMode=true` 让后端注入上一批**完整**交付），让总控产出一段「承上启下」说明；把这段说明（而非机械 `priorSummary`）作为下一 stage 席位 task 的上下文 / 或广播给下一批席位 thread（复用 `POST /threads/{id}/messages/append`）。
+- **下一批仍由计划钉死**：leader 中转轮**不**自由决定派给谁（计划已定 D、E）；可参考 `buildChainLeaderTask` 的「约束 leader 只派给指定席位」思路，或干脆 leader 只做综合、前端照计划派 D、E 并把 leader 综合 + 广播注入其 task。
+- **与「并行禁写」「§12.1 放开搜索」并存**：中转/广播不影响工具面。
+- **与致命 bug 修复并存**：最后一个 stage 跑完仍走「交回总控（`runOrchestration`）收口/继续派活」；用户干预仍走 leader、不重跑 DAG。
+
+**影响文件（预估）**：`hooks/useStep2Orchestration.ts`（`runDagOrchestration` 的 stage 循环里加 leader 中转 + 广播收齐）、可能复用后端 `_leader_run`（synthesisMode 注入全文）/ `/messages/append`（广播）/ `/last-ai-message`（收齐交付）。后端基本无需新接口。
+
+**✅ 实施结论（2026-06-07）**：后端**零改动**，全部在前端 `runDagOrchestration` 内完成，复用既有「传摘要按需传全文」优化链路：
+
+1. **中转轮位置**：每个**非最后**的 stage barrier 到达后（`Promise.all` 收齐本批交付），插入**一轮 leader**「中转轮」，展示为「总控协调（承上启下）」气泡。最后一个 stage 后**不**插中转，综合/收口仍交给末尾的 `runOrchestration` 接管（与致命 bug 修复一致）。
+2. **可靠收齐交付（传摘要）**：中转轮跑 `streamMultiAgent({agentType:"leader", synthesisMode:false})`。后端 `_leader_run` 本就在每轮 leader 前用 `_collect_delivery_status`（走**轻量 `GET /last-ai-message?max_chars=600` 接口**）**客观核对**各席位真实交付并把**摘要**注入总控输入（`_build_seat_status_block`）——比 detached 广播可靠（直接实读各席位 thread，不依赖 best-effort 广播是否落地）。故中转轮传 `synthesisMode:false`：只综合本批、**不收口**，只注入摘要；**完整交付正文**留到末尾收口的 synthesis 轮（`_build_full_deliverables_block`，全 ✅ 才注入）按需读取——即「**传摘要按需传全文**」。
+3. **承上启下驱动下一批**：中转轮产出的综合说明存进 `leaderBridge`，作为**下一 stage** 席位 task 的上下文（`buildStageTask({priorSummary: leaderBridge, priorIsBridge:true})`，措辞为「承上启下综合说明」而非机械「交付摘要」），替代原来的 `buildDependencySummary(deliveries)`。中转失败/无产出时回退机械依赖摘要，不阻断。
+4. **下一批由计划钉死**：中转轮提示（`buildDagTransitTask`）明确告知总控「下一阶段席位已由编排计划钉死为 X、Y，你**不要**自行 `agent_orchestration` 派活、**不要**收口」，前端仍照计划直派下一批；即便弱模型仍派了活，前端忽略其 `dispatched`、只取 `content` 当 bridge。
+5. **广播**：本批输出广播给其它席位 + 总控 = 后端 `_special_run` 既有 detached 后广播（截断摘要）；承上消息给下一批 = 注入其 task `new_message`（席位 run 输入必见，比 `/messages/append` 更可靠，省一次写盘）。
+6. **澄清/抢占/失败**：中转轮触发澄清 → 暂停 DAG（回复后走 leader 自由派活、不重跑 DAG，沿用 `dagPlanExecutedRef` 闸门）；被 `isStale()`/abort 抢占 → 静默收尾；异常 → 该气泡标错误、清空 bridge 继续。
+
+**纯函数**：`lib/dag-types.ts` 新增 `buildDagTransitTask`（中转轮提示）+ `buildStageTask` 加 `priorIsBridge` 形参；`lib/dag-types.test.ts` 加 4 个单测（共 27 个全过）。
+
+> ⚠️ **§12.3 的「单独中转轮 + 前端直派」已被 §12.4 取代**（2026-06-07 同日）：见下。`buildDagTransitTask` / `buildStageTask` / `buildDependencySummary` 仍保留在 lib（带单测），但 `runDagOrchestration` 不再调用它们。
+
+### 12.4 ✅ 需求再变更：DAG 改成「总控驱动每 stage 派活」（2026-06-07，§3.2 方案 A）
+
+**新诉求（用户原话）**：把并行(DAG)逻辑改得和串行一样——串行时总控给多个智能体派活、它们完成后汇报给总控、总控再继续往下派活；并行也改成「由总控判断要执行哪些步骤，这些步骤完成后再汇报给总控，总控继续往下派活」。
+
+**已确认的两个关键决策**：
+1. **每批「派给谁」**：✅ **计划钉死成员，但走总控派活**（不是总控自由乱派）。即 stage 成员仍由编排计划定死，但改成总控每轮**真正** `agent_orchestration` 派活给这些席位（约束只派给它们、且每个都派到）。= §3.2「方案 A」+ 批内并行。
+2. **适用范围**：✅ **只改 dag 模式**（recommend 仍串行逐个、chain 不动）。
+
+**实现（后端零改动，全在 `runDagOrchestration`）**：每个 stage 两步——
+- **(a) 总控派活轮**：跑一轮 `leader`，提示 `buildDagStageLeaderTask`（首 stage 带任务背景；后续 stage 靠后端注入的此前交付摘要承上；列出本 stage 钉死席位的 `agent_name`，要求逐个派到、不派清单外、不收口）。`synthesisMode:false` → 后端 `_build_seat_status_block` 走轻量 `last-ai-message` 注入各席位**摘要**（传摘要按需传全文）。
+- **(b) 批内并行**：本 stage 席位并行跑总控派给各自的 task——`pickDagSeatTask(leaderRes.dispatched, content, agentId, name)` 命中其 `agent_name`；总控漏派/写偏则回退总控正文/模板，**不借用别席位 task**（多席位并行避免张冠李戴）。完成后交付经后端 `_special_run` detached 后广播回总控；下一 stage 的派活轮即可看到。
+- barrier 后进入下一 stage，总控再派下一批。全部 stage 跑完 → 交回 `runOrchestration` 收口（synthesisMode 按需注入全文）。
+
+**相比 §12.3 的变化**：§12.3 是「前端直派 + stage 间单独插一轮只综合的中转轮」；§12.4 把**每个 stage 本身**就改成「总控派活轮 + 批内并行」——总控既承上（注入的摘要）又派活，不再需要单独的中转轮。与 chain 模式同构，区别是一次钉死一批、批内并行。
+
+**纯函数**：`lib/dag-types.ts` 新增 `buildDagStageLeaderTask`（每 stage 派活提示）+ `pickDagSeatTask`（取某席位 task，多席位不张冠李戴）；`lib/dag-types.test.ts` 加 5 个单测（共 32 个全过）。`runDagOrchestration` 不再用 `buildStageTask/buildDependencySummary/buildDagTransitTask`（保留在 lib）。
+
+**Phase 7 流程图兼容**：总控派活轮无席位 active + `isOrchestrating` → 流程图「总控」节点显示 active（承上派活中），随后该 stage 列点亮，无缝衔接。
+
+**下次实地验收**：①每个 stage 前出现「总控协调（派活中/承上派活中）」气泡,内容是总控对本 stage 席位的派活说明;②后端日志该轮 leader 的 `_partition_dispatch` 派给的正是本 stage 钉死席位;③这些席位并行跑(special 日志时间重叠);④完成后下一 stage 总控派活轮能看到上一批交付摘要(`[leader-roster]` 日志)。
+
+### 12.5 ✅ 流程图弹窗化 + DAG「快速/沙箱」执行子模式（2026-06-07）
+
+三个改动一起做:
+
+**(1) 流程图改成弹窗**:Step2 顶部不再内联 `DagFlowChart`(挤占两列消息高度,截图 `样式优化-1.png`)。改成一条细栏「分层编排执行中 · 共 N 个阶段 ＋ [查看编排流程图]」按钮,点开 `Dialog` 看**全尺寸**流程图(非 compact)。编辑器(`BusinessChainEditorPage`)底部预览保持内联不变。改 `Step2Panel.tsx`(加 `dagFlowOpen` state + Dialog)。
+
+**(2) 推荐弹窗新增 DAG 执行子模式(快速/沙箱)**:`BusinessChainPicker` 在选中链条**有分层并行**(走 dag)时,「进入研讨」旁出现「执行方式:快速·双列禁写 / 沙箱·单列可写」二选一(只 dag 时出现,§已确认)。
+   - **快速(`fast`,默认)**:同 stage 席位**并行**、主区**双列**、`parallelNoFile=true`(seat_parallel **禁写文件**)。= 之前的行为。
+   - **沙箱(`sandbox`)**:同 stage 席位**仍并行**,但主区**单列**(`selectedParallelSeats` 最多 1)、`parallelNoFile=false`(seat policy **允许写文件**);点头像切换查看,沙箱跟随当前席位。
+   - 数据流:`SeatSelectionResult.dagExecMode` → `RoundtablePlanningPage` state(持久化进 `DraftStep2(Run)Snapshot.dagExecMode`,mirror orchestrationPlan)→ `useStep2Orchestration` option → `runDagOrchestration`。
+
+**(3) 沙箱跟随当前显示席位(防 bug 重点,用户特别强调)**:`useStep2Orchestration`
+   - `sandboxFollowThreadIdRef` = 当前显示席位的 thread;`openSeatVirtualArtifact` 的 auto 守卫:sandbox 模式下,**后台并行席位**写文件时若不是当前显示席位,**不自动打开**(否则沙箱内容和主区列表错位)。
+   - 切换显示席位的 effect(keyed on `selectedParallelSeats` + `dagExecMode`):该席位**有产物**(stub 里有 write_file/str_replace)→ `openSeatLatestArtifact` 强制打开它最新的文件;**无产物**→ 关闭沙箱面板(`setActiveArtifactThreadId(null)` + `deselectArtifact` + `setArtifactsOpen(false)`)。
+   - 当前显示席位 live 写文件 → `handleArtifactToolPhase` auto-open,守卫放行(follow===该席位)。后台席位写 → 守卫拦掉、只缓存 stub;切到它时 effect 再打开。
+   - `toggleParallelSeat`:sandbox 单列 = 点头像切换(始终保留 1 个,不取消到空);fast 双列 = 原 LRU 2 个。
+
+**改动文件**:`lib/business-chain.ts`(SeatSelectionResult.dagExecMode)、`components/BusinessChainPicker.tsx`(子模式 UI)、`api/drafts.ts`(快照 dagExecMode)、`pages/RoundtablePlanningPage.tsx`(state/snapshot/hydrate/confirm/reset 全链)、`hooks/useStep2Orchestration.ts`(option + parallelNoFile/单列 + 沙箱跟随 + toggle cap)、`components/Step2Panel.tsx`(流程图弹窗 + 单列 grid)。typecheck 零新增(基线 65),dag-types 32 单测全过。
+
+**下次实地验收(沙箱跟随是重点)**:①推荐弹窗选有并行的链条 → 出现「快速/沙箱」二选一;②快速=双列禁写(无沙箱);③沙箱=单列、席位能写文件、点头像切换列表时沙箱内容**同步**切换:有产物显示、无产物关闭;④后台席位写文件不会把沙箱抢到非当前列表;⑤流程图点按钮弹窗、全尺寸、节点随执行点亮。
+
+### 12.6 ✅ 修:并行席位「跟着派活」（2026-06-07）
+
+**现象**(截图 `bug-1.png`):总控派活后,并行席位的气泡里显示的是**总控的整段派活叙述**(「我来调度各智能体…第1阶段任务清单:席位1…席位2…」),还去调 `skill_list` 找 `agent_orchestration`——席位在**模仿派活**。
+
+**根因**:总控这轮**没真正调用 `agent_orchestration` 工具**(弱模型 deepseek 用文字罗列了派活计划)→ 后端解析的 `dispatched=[]` → 前端 `pickDagSeatTask` 回退把**总控整段叙述**喂给**每个**席位 → 席位照抄叙述、模仿派活。(席位本就被 run policy 禁了 `agent_orchestration`,**派不了活**,只是空转一轮叙述 + 调 `skill_list`。)
+
+**修 v1(护栏,效果不足)**:`pickDagSeatTask` 加角色边界护栏 + 回退措辞改「挑出属于你的那份」;`buildDagStageLeaderTask` 加「必须真正调用工具」。→ **没拦住**:总控对 deepseek 仍只写文字不调工具(`dispatched` 还是空),席位拿到的**任务正文本身**就是那段「我来调度…席位1/2/3」,护栏被淹没;3/4 席位仍模仿派活,有的甚至绕道 `bash`+`python requests.get('/api/agents')` 调内部接口派活(bug-1~4)。
+
+**✅ 修 v2(根治:回退绝不注入派活叙述)**:`pickDagSeatTask` 去掉 `leaderContent` 入参——
+- **命中**总控结构化派活(真调了工具)→ `请你作为「X」，完成总控派给你的本阶段任务：<dispatched task>` + 护栏;
+- **未命中 / `dispatched` 空**(总控只写文字)→ **绝不**把总控派活叙述喂给席位,改给**干净本职任务**:「请你作为「X」,从你的专业职责出发,独立完成本阶段属于你的分析与交付。任务背景与此前各阶段交付已在你的会话上下文里(后端广播注入),据此承接」+ 护栏。护栏强化到「不要用 bash/python/脚本访问内部接口(/api/agents、agent_orchestration)派活、不要复述『我来调度』总控口吻」。
+- `buildDagStageLeaderTask` 的「必须真正调用工具」保留(让命中率更高、尽量走 exact-match)。
+- `dag-types.test.ts` 改 2 单测(共 33 过)。typecheck 65。
+
+> ⚠️ **残留次要污染源(若仍复发再处理)**:DAG 每个 stage 的 leader 轮,后端 `_leader_run` 会把 leader 的输入(含「请你作为总控…派活」)**预广播**进所有席位线程(`总控智能体收到用户消息:…`)。席位的**当轮任务**已干净(修 v2),这条只是历史上下文,理论上被「最新的干净任务 + 护栏」压制。若实测仍模仿派活,下一步:后端给 DAG leader 轮加 `suppress_pre_broadcast` / 或广播一条**净化**过的背景(去掉派活措辞)。
+
+### 12.7 ✅ 修 4 项(2026-06-07):席位仍派活(v3 后端)+ 沙箱关不掉 + 并行不自动下滑 + 流程图只到 Step2
+
+实测 §12.6 仍有席位派活(视觉设计师 `skill_manage` 找 agent-orchestration、列 dispatch all 4)——**坐实**了「残留次要污染源」:后端 leader 预广播把派活 prompt 推进席位线程,弱模型从历史里捡到派活意图。一起修了 4 项:
+
+1. **席位仍派活(根治·后端)**:`_leader_run` 加 `suppress_pre_broadcast` 参数;DAG「每 stage 派活轮」前端传 `suppressPreBroadcast: true`(`api/multi-agent.ts` → `suppress_pre_broadcast`,run/stream 读取)。为真时:**不**把总控派活 prompt 预广播给席位、**也不**把「总控给 X 派活」detached 广播给兄弟席位。recommend/chain 不传该 flag,行为不变。配套:`pickDagSeatTask` 加 `seedMessage` 入参——预广播抑制后席位线程没有用户原始消息了,把**任务背景**直接写进席位 task(此前各阶段交付仍由 special 完成后广播注入)。→ 席位线程里**任何地方都没有派活语句**,根治模仿。
+2. **沙箱关闭按钮关不掉**:沙箱跟随 effect 之前每次 render(deps 身份变)都重跑 → 把用户刚关的沙箱强制重开。加 `lastReconciledSeatRef` 守卫:**只在显示席位真正变化时**才开/关沙箱;用户手动关闭(席位没变)时 effect 早退,不再回弹。
+3. **并行时自动下滑失效**:平铺列表 ↔ 网格(两列/单列)切换时 `scrollHeight` 突变、`scrollTop` 被浏览器 clamp → `useAutoScroll` 误判「用户上滚」而停跟随。`Step2Panel` 加 effect:`isParallelRunning` / `selectedParallelSeats` 变化时 `scrollStep2ToBottom()` 重新拉到底 + 恢复跟随。
+4. **流程图只展示 Step2**:`DagFlowChart` 加 `showReportMilestone`(默认 true);Step2 弹窗 + 编辑器预览传 `false` —— 只到「共识」(Step2 终点),去掉「结果绘制」(那是 Step3)。
+
+**改动**:后端 `multi_agent.py`(`_leader_run` suppress 两处广播 + run/stream 读 flag);前端 `api/multi-agent.ts`、`lib/dag-types.ts`(pickDagSeatTask + seedMessage)、`hooks/useStep2Orchestration.ts`(传 flag + seed + 沙箱跟随守卫)、`components/Step2Panel.tsx`(自动下滑 effect + showReportMilestone)、`components/DagFlowChart.tsx`、`pages/BusinessChainEditorPage.tsx`。`dag-types.test.ts` 共 **34 单测过**;前端 tsc 65 基线零新增;后端 `py_compile` OK。
+
+### 12.8 ✅ 席位产出 md 文件 + 禁写 .py（2026-06-07）
+
+**现象**:某次 7 席位**全都没产出 md 文件**;且一直有的问题——席位**有时写 .py 脚本**(用户要求:不写 .py,其它格式可以)。
+
+**根因(没 md)**:两层都堵了——(a)**快速模式** `seat_parallel` policy 禁了 `write_file`(原「产物走正文」设计);(b)DAG 席位**提示词**写的是「直接输出你的交付正文」,即使沙箱模式(允许写)也不会去写文件。
+
+**修**:
+1. **后端 policy 放开写文件、统一禁 bash**(`roundtable_run_policy.py`):
+   - `seat_parallel`:去掉 `write_file` / `str_replace` 禁用(**可写 md**),保留禁 `bash` + 打断/越权类;仍放开 `web_search`。
+   - `seat`:新增禁 `bash`(原来允许)——圆桌席位是「文档产出者」,不该跑 shell/python 脚本(弱模型爱写 .py 再跑生成产物,乱且抓不到预览);改为**直接 write_file 写成品文档**。
+   - `report`:`bash` 已随 `seat` 禁,改为 `[*_SEAT_EXCLUDED, "str_replace"]`(集合不变)。
+   - 测试 `test_roundtable_run_policy.py`:`test_seats_can_write_files_but_not_run_bash`(seat / seat_parallel 都可写文件、都禁 bash),6 用例过。
+2. **前端提示词**(`pickDagSeatTask`)加「产物要求」:**把完整交付写成一个 .md 文件**(write_file 到 outputs)+ 正文给摘要;**禁写 .py 或任何脚本文件**,.md/.html/.txt 等其它格式都可以,唯独不要 .py。
+3. **快速模式(双列)不自动开沙箱**(`openSeatVirtualArtifact` 新增守卫):放开写文件后,双列里多席位并发写文件会让单沙箱预览反复串台——fast 模式 DAG 并行批次**完全不自动开沙箱**(文件仍写盘,Step3/文件卡可查看);沙箱模式(单列)仍按「沙箱跟随当前席位」预览。
+
+**关于 .py 的强度**:`write_file` 是全局工具(所有 agent 共用),无法在网关层按扩展名硬拦,故 .py 禁止走**提示词**(强约束)+ **禁 bash**(写了也跑不了,脚本生成产物的动机被掐断)。若实测仍偶发写 .py 且需**硬拦**,下一步:给 lead_agent 的 `write_file` 工具加一个「按 run context 禁某些扩展名」的开关,网关 `_run_payload` 对圆桌席位置 `[".py"]`(只影响圆桌 run,不动其它 agent)。
+
+**改动**:`roundtable_run_policy.py`、`test_roundtable_run_policy.py`、`lib/dag-types.ts`、`lib/dag-types.test.ts`(35 过)、`hooks/useStep2Orchestration.ts`。前端 tsc 65、后端 py_compile OK + 6 policy 单测过。⚠️ **改了后端,需重启 Gateway**。
+
+### 12.9 ✅ 席位「按需取前序全文」只读工具 read_peer_delivery（2026-06-07）
+
+**诉求**:A,B,C → D,E 时,D,E 默认拿 A,B,C 的**摘要**,但识别到需要**全文**时也能取到。之前只有总控(leader)能「摘要默认+按需全文」(跨 thread 读),下游席位**不能**(席位间 thread 隔离、只有 1500 字截断广播)。
+
+**实现**(真·按需,全文只在调用工具时才进 LLM 上下文):
+1. **新 harness 只读工具** `read_peer_delivery(seat_name)`(`packages/harness/deerflow/tools/builtins/roundtable_peers_tool.py`):从 `runtime.context["roundtable_peer_deliveries"]`(网关注入的 `[{name,content}]`)按席位名取全文;空名→列出可取席位;非圆桌场景→「无」。只读 context dict,**不跨 thread、不碰 sandbox、无网络**,纯 `deerflow.*`(不违反 harness→app 防火墙)。注册进 `tools/tools.py` 的 builtin(始终在,只读无副作用)。
+2. **网关注入 context**:`_run_payload` 加 `extra_context`;`_special_run` 收 `peer_deliveries` → 注入 `context.roundtable_peer_deliveries`;run/stream 读 `peer_deliveries`(规整 `[{name,content}]`)。**不进 prompt → 不调工具就不耗 token**。
+3. **run policy**:`read_peer_delivery` 从 `leader`(总控自己跨 thread 读,不需要)+ `report`(Step3 不读前序)排除;**席位(seat/seat_parallel)保留**。
+4. **前端**:`runDagOrchestration` 跨 stage 累积**完整交付** `priorDeliveries`,stage>0 席位的 special run 带 `peerDeliveries`(`api/multi-agent.ts` → `peer_deliveries`);`pickDagSeatTask` 加 `hasPeers` 形参,有前序时在 task 里提示「需要某前序席位全文时调用 read_peer_delivery('<名>'),平时用摘要」。
+
+**最终语义**:D、E 默认看 A、B、C 的**摘要**(1500 字广播);识别到不够 → 调 `read_peer_delivery('情报收集')` 取**全文**。总控仍是摘要默认+综合轮全文。**= 用户要的「摘要默认、按需全文」对席位也成立了。**
+
+**改动**:后端 `roundtable_peers_tool.py`(新)、`tools/tools.py`、`roundtable_run_policy.py`、`multi_agent.py`;前端 `api/multi-agent.ts`、`lib/dag-types.ts`、`lib/dag-types.test.ts`(36 过)、`hooks/useStep2Orchestration.ts`。前端 tsc 65;后端 py_compile OK + 6 policy 单测过 + 工具导入/行为 smoke 通过。⚠️ **改了后端 + 新增 harness 工具,需重启 Gateway**。
+
+### 12.10 ✅ 修:沙箱模式第一个席位不自动开沙箱（2026-06-07，前端）
+
+**现象**:沙箱(单列)模式并行时,**第一个**席位的消息列表不自动打开沙箱(要手动开);切换到其它席位时正常自动打开。
+
+**根因**:沙箱跟随 effect(§12.5)在选中席位**还没写产物**时走「关闭沙箱」分支,里面同时调了 `deselectArtifact()` **和** `setArtifactsOpen(false)`。后者是 context 的 **wrapped setOpen**(`context.tsx:73`):`关闭时若 autoOpen 为真 → 把 autoOpen 置 false`。于是第一个席位刚选中(还没写文件)→ autoOpen 被关 → 该席位**随后 live 写文件**时,`openSeatVirtualArtifact` 的 `!flags.autoOpen` 守卫拦掉自动打开。切换到**已写过**文件的席位能开,是因为那条路走 `openSeatLatestArtifact`(force,auto=false,绕过 autoOpen 守卫)。
+
+**修**(一行):关闭分支只保留 `deselectArtifact()`(它走 raw `setOpen(false)`,**不**动 autoOpen),删掉多余的 `setArtifactsOpen(false)`。这样面板关掉、但 autoOpen 仍为真 → 第一个席位 live 写文件时正常自动开沙箱。(若用户**手动**关过沙箱,autoOpen 本就为 false,不会自动重开 —— 尊重用户。)改 `hooks/useStep2Orchestration.ts` 沙箱跟随 effect。tsc 65。
+
+### 12.11 ✅ 修:快速模式又生成文件了 + Fragment 警告（2026-06-07）；记录无关 404
+
+1. **快速模式不应生成文件(回退 §12.8 的过度放开)**:§12.8 为「让席位产 md」把 `seat_parallel`(快速模式)也放开了 write_file —— 但**快速模式(双列)的设计就是产物走正文、不写文件**,写文件归**沙箱模式**(单列 + 沙箱预览)。修:
+   - `roundtable_run_policy.py`:`seat_parallel` 重新**禁 write_file / str_replace**(保留禁 bash);`seat`(沙箱模式)仍可写。
+   - `useStep2Orchestration.ts`:`parallelNoFile = dagExecMode !== "sandbox"`(快速模式一律禁写,含单节点 stage;沙箱模式放开)。
+   - `pickDagSeatTask` 加 `allowFiles` 形参:沙箱(true)=写 .md 文件 + 禁 .py;快速(false)=产物走正文、不写文件。hook 按 `dagExecMode === "sandbox"` 传。
+   - 测试:`test_sandbox_seat_writes_files_fast_parallel_does_not`(6 过);`dag-types.test.ts` 拆成沙箱/快速两个产物要求用例(37 过)。
+   - **语义**:快速=双列、产物走正文、不写文件;沙箱=单列、写 .md、沙箱跟随预览。
+2. **`Invalid prop data-lov-id supplied to React.Fragment`**:`DagFlowChart` 的 stage 循环用了具名 `<Fragment key>`,dev 代码标注插件(lovable-tagger)给它注入 `data-lov-id`,而 Fragment 只接受 key/children → React 警告。修:换成 `<div className="contents" key=...>`(display:contents 不生成盒子,Connector/StageColumn 仍是外层 flex 直接子项,布局不变,且能接收 data-*)。移除 `Fragment` import。
+3. **(无关,非本期引入)`/api/getTokenByEmail?email=…%40local.deerflow` 404 ×60**:来自 `src/core/studio/api.ts` 的 `fetchStudioToken`(studio/expert-auth 引导),用户邮箱被映射到 legacy `@local.deerflow` 域、后端 `getTokenByEmail` 不认 → 404,React Query 跨多个 `useStudioToken` 调用点重试 → 重复多次。**与圆桌 DAG 改动无关**(圆桌头像是本地 SVG,本期未新增任何前端 GET)。需要的话单独排查 studio token 链路。

+
+## 13. 实施进度（截至 2026-06-06，下次会话续）
+
+| Phase | 内容 | 状态 |
+|---|---|---|
+| 1 | DAG 数据模型 + 校验 + 持久化字段（`lib/dag-types.ts`，24 单测） | ✅ 完成 |
+| 2 | 分层编辑器（**做进业务链条页**）：链条加 `stages` 字段（前后端 + alembic `20260607_03` + 11 后端单测）；`BusinessChainEditorPage` 竖列分组 Stage（DnD + 按钮）；纯逻辑 `lib/chain-stages.ts`（19 单测） | ✅ 完成 |
+| 3 | `runDagOrchestration`：批内 `Promise.all` 并行 + 批间 barrier 串行 + 依赖摘要注入（方案 B 前端直派） | ✅ 完成 |
+| 4 | 并行 run policy `seat_parallel`（`roundtable_run_policy.py` + `multi_agent.py` 读 `parallel_no_file`，6 后端单测）；**§12.1 方案 A 已放开 web_search/技能** | ✅ 完成 |
+| 5 | 并行显示：收起左侧 + 头像条 + 两列 + 选中切换 | ✅ 完成（本轮修了侧栏/Markdown/字数） |
+| 6 | 流式高性能：ref 全量累积 + 节流 flush（仅选中渲染） | ✅ 完成 |
+| 7 | DAG 流程图执行态可视化（`DispatchChainModal` 复刻成按 stage 分列；后改成**弹窗**见 §12.5） | ✅ 完成（2026-06-07） |
+
+**端到端闭环已通**：链条页编排分层 → 存库 → 选链条进 Step2 → `runDagOrchestration` 并行直派 → 各阶段完交回总控派活/收口。
+
+**✅ §12.3 已实施（2026-06-07）**：见 §12.3「实施结论」。`runDagOrchestration` 在每个非末尾 stage barrier 后插入 leader 中转轮（`synthesisMode:false` 走轻量 `last-ai-message` 注入摘要、收口轮才按需全文），承上启下驱动下一批；后端零改动；`dag-types.ts` 加 `buildDagTransitTask` + `buildStageTask.priorIsBridge`，27 单测全过。
+
+**下次会话 TODO（优先级从高到低）**：
+1. **运行时实地验收 §12.3**：①每个 stage 之间出现「总控协调（承上启下）」气泡，内容是对上一批的综合；②后端日志中转轮 `[leader-roster] ... 注入席位交付状态` 显示上一批 ✅、未跑的 ⬜；③下一 stage 席位 task 里带的是总控承上说明（非机械摘要）；④中转轮不应真的派活（即使派了前端也忽略）。
+2. 运行时实地验收（旧）：①§12.1 后并行席位能搜索、步骤条显示；②并行 special 日志时间重叠 + `Excluded` 不含 web_search 含 write_file；③用户干预后是「总控派活」而非重跑 DAG；④最左全局侧栏 + 参与角色栏并行收起且不回弹。
+3. **✅ Phase 7 DAG 流程图可视化已完成（2026-06-07）**：见 §7.2。`DagFlowChart` 组件 + 编辑器只读预览 + Step2 执行态缩略(`dagNodeStates` 实时驱动)。
+4. （可选）串行也确定性注入上一轮交付摘要。
+
+**关键文件速查**：
+- 前端：`hooks/useStep2Orchestration.ts`（`runDagOrchestration` / `dagPlanExecutedRef` / 并行 store+flush）、`components/Step2Panel.tsx`（两列+头像条）、`components/ParallelSeatStrip.tsx`、`lib/dag-types.ts`、`lib/chain-stages.ts`、`pages/BusinessChainEditorPage.tsx`、`pages/RoundtablePlanningPage.tsx`（侧栏收起 effect + handleConfirmAgents dag 分支）、`components/BusinessChainPicker.tsx`（链条→dag）。
+- 后端：`app/gateway/roundtable_run_policy.py`（`seat_parallel`，**待放宽**）、`app/gateway/routers/multi_agent.py`（`_special_run` 读 `parallel_no_file`）、`persistence/roundtable_chains/`（`stages` 列）、`migrations/versions/20260607_03_chain_stages.py`。
+- 测试：`frontend-web` 用 esbuild 转译 `.test.ts` 后 `node --test`（项目无 vitest）；后端 `PYTHONPATH=. uv run pytest tests/test_roundtable_chain_stages.py tests/test_roundtable_run_policy.py`。
