+- Viewport: 1280 × 720. Light route: `#/page/strategy/qa/position-roundtable`; dark embedded route: `#/page/strategy/qa/position-roundtable?embed=1&theme=dark`.
+- State: local browser has no authenticated API session. The original intent API is invoked and reports `Authentication required`; business-chain and agent endpoints return no usable data.
+
+**Findings**
+
+- [P1] Populated agent and business-chain states cannot be compared yet.
+  Location: right agent list and non-planning-role chain diagram.
+  Evidence: reference images show populated cards and nodes; the implementation has `0 个` agents and no available business chain in the unauthenticated preview.
+  Impact: card density, selected-card indicator, chain node flow, and agent-detail transition cannot be truthfully verified against live data.
+  Fix: verify the route in an authenticated session with at least one public chain and tagged agents.
+
+**Open Questions**
+
+- The final business-chain stage arrangement is still pending product confirmation. The compact graph maps whatever stage configuration is returned, while intentionally omitting dependency-label text as requested.
+
+**Implementation Checklist**
+
+1. Left task panel is now display-only and retains its independent position-roundtable task adapter.
+2. Business-chain selection uses the original roundtable card/radio/relationship-entry pattern.
+3. Every position uses the original `useStep1Intent` interface and `Step1Panel` message list/input panel; only the position header changes.
+4. The right switch now uses the exact `课题研究 / ai写作` segmented-control treatment (light gray track, white active state; dark blue glass equivalent).
+5. The embedded layout widens the left panel to 360px and applies the deep-blue right-panel tokens used by the reference.
+6. Other roles render a taller top-to-bottom card-node flow without dependency labels. The canvas supports mouse-drag panning, and each node retains only a name plus a single-line description.
+
+**Follow-up Polish**
+
+- [P3] If live content is unusually long, tune the compact flow node width or horizontal scrolling after seeing the production chain data.
+
+**Comparison history**
+
+- Iteration 1: task fields were editable and the right TDesign card tabs looked unlike the reference. Replaced the task form with display-only information and replaced the tabs with the existing `课题研究 / ai写作` segmented switch.
+- Iteration 2: business-chain selection was a dropdown and the flow was vertical avatar chips. Replaced it with original-roundtable selection cards and compact business-chain configuration-style node cards with link lines but no dependency labels.
+- Iteration 3: dark right-panel background differed from the supplied deep-blue reference. Applied the `#032650` / `#042b59` / `#2b8ffe` token family and captured the revised embedded dark state in the full-view comparison.
+- Iteration 4: removed the custom disabled input from non-planning positions and reused the original roundtable input panel. Enlarged the left flow viewport, retained its connection lines, and removed node level/seat/status metadata.
+- Iteration 5: converted the compact flow from left-to-right to top-to-bottom. Added mouse-drag panning and single-line description truncation; populated-chain visual QA remains blocked by the unauthenticated preview.
+- Iteration 6: constrained the flow canvas to its card viewport, narrowed nodes from 190px to 158px, and realigned branch gaps plus connector anchors to prevent clipping and offset lines.

+# 岗位会商交付闭环与内置智能体实现计划
+
+> 页面：`/page/strategy/qa/position-roundtable`
+>
+> 目标：在现有岗位会商基础上补齐“产物交付、查看、驳回、方案总结、行动规划”的完整闭环，同时继续保持原多智能体会商页面不受影响。
+
+## 实施核对（2026-07-21）
+
+本计划已按“岗位会商独立路由、无总控、各席位直接问答”的边界完成第一轮闭环。实际流程调整为：
+
+```text
+任务信息 → 情报分析岗识别并确认意图 → 启动校验并冻结业务链
+→ 分阶段席位直接问答/交付 Markdown → 全部有效交付
+→ 方案总结智能体（roundtable-summary）→ 行动规划智能体（position-action-planner）
+→ 可随时返回交付产物驳回 → 后续阶段及内置产物级联失效 → 重做后重新收口
+```
+
+- [x] 情报意图、业务链选择、席位岗位归属和席位智能体配置均在启动前校验；启动后保存业务链快照。
+- [x] 普通席位直接调用各自分配的智能体，并注入任务、意图及已完成上游席位的问答/产物；不经过总控智能体。
+- [x] 普通席位必须在 `outputs` 中交付 Markdown 才会完成；情报分析岗以确认的结构化意图完成为准。
+- [x] 节点、交付卡片、流程图和大图弹窗均展示 `locked / ready / running / done / rejected / stale / error` 状态，并可回看节点会话和产物。
+- [x] 驳回要求标题和理由；当前节点转为 `rejected`，后续阶段按依赖转为 `stale/locked`，总结和行动规划同时失效，历史内容保留可查看。
+- [x] 被驳回或失效的普通席位必须写入一份**新的或已改写** Markdown 才能再次完成；单纯继续问答且没有新交付不会误使下游产物失效。
+- [x] 方案总结复用 `roundtable-summary` 的真实流式线程；行动规划新增 `position-action-planner`，强制输出 Markdown 报告和 `action-plan-subtasks.json`。
+- [x] 两个内置智能体的线程、产物快照和来源节点版本栅栏均持久化；流式期间若上游版本变化，旧运行不能覆盖最新状态。
+- [x] 右侧“交付产物”可查看内置节点结果、继续同一线程问答/修改交付，并在打开 Markdown 沙箱时自动收起右栏。
+
+设计收敛：当前版本以节点的 `artifact_manifest`、`latest_answer`、版本、驳回记录及 Session 内置快照作为唯一事实来源，已能覆盖统一产物卡片和级联逻辑，因此不新增重复的 `position_roundtable_deliverables` 表。若后续需要“单个文件独立驳回、跨会话检索或完整版本对比”，再将清单归一化为独立产物表，避免现在的双写一致性风险。
+
+## 数据持久化与灾难恢复（2026-07-23）
+
+岗位会商现在使用“两层持久化”，两层职责不同：
+
+1. LangGraph checkpoint/thread 是智能体继续推理与流式问答的执行源。
+2. `position_roundtable_sessions` / `position_roundtable_nodes` 是页面历史的数据库恢复源。
+
+数据库恢复源会保存：
+
+- 情报分析岗完整消息、步骤时间线和未发送输入草稿；
+- 每个业务链岗位的完整消息和未发送输入草稿；
+- 方案总结、行动规划两个收口智能体的完整消息和未发送输入草稿；
+- 已确认意图、冻结任务与业务链快照、节点状态、版本、驳回记录；
+- Markdown / JSON 等文本产物正文（单文件最多 400 万字符）和文件元数据。
+
+因此即使线上重启后 checkpoint 或沙箱 outputs 卷丢失，历史页仍能从数据库展示对话与产物正文，后续收口智能体也能继续读取数据库中的有效上游交付。新任务在意图识别开始前就会创建 Session，用户不必等到“启动业务链”才获得持久化保护。历史下拉支持删除，删除会显式清理 Session 与全部节点恢复快照，不依赖 SQLite 外键开关。
+
+对应迁移：`20260723_05_position_roundtable_conversations.py`。部署时必须执行到 Alembic head。
+
+## 0. 核心结论
+
+- 方案总结智能体建议复用现有会商里的 `roundtable-summary` 能力，但不要直接搬整套 Step 3 页面流程。
+  - 可复用：内置智能体 ID、总结报告 prompt 组织方式、Markdown 报告产物、流式对话、报告续问与文件预览能力。
+  - 需要改造：输入材料从“总控共识 + 各席位交付”改成“任务信息 + 意图结果 + 已通过的岗位产物 + 业务链快照”，并把结果存到岗位会商 Session 下。
+- 行动规划智能体建议作为新的内置智能体新增。
+  - 输入：方案总结报告、各岗位最终有效产物、业务链阶段信息、任务意图。
+  - 输出：行动规划报告、结构化子任务清单。
+- 这个模式仍然不需要总控智能体。情报分析岗负责意图识别，业务链节点直接调用各自配置的智能体，最终再由内置总结/规划智能体收口。
+- 驳回不删除历史内容，只改变“当前有效版本”的状态；被驳回节点和后续节点需要重新交付，既保留可追溯性，也方便后续返回查看。
+
+## 1. 目标业务流程
+
+1. 情报分析岗进入页面，查看任务信息并完成意图识别。
+2. 用户点击“确认意图并启动业务链”。
+3. 启动前做校验：
+   - 未选择业务链：提示“请先选择业务链”。
+   - 业务链存在未配置岗位的席位：提示并引导去业务链配置页。
+   - 业务链席位缺少智能体：提示具体席位名称。
+   - 意图尚未完成：提示先完成任务意图识别。
+4. 校验通过后冻结业务链快照，初始化岗位会商节点。
+5. 各岗位只对分配给本岗位的智能体进行问答。
+6. 节点问答完成后形成交付产物，右侧产物卡片显示“已完成 / 未完成 / 进行中 / 已驳回 / 已失效”。
+7. 左侧流程图显示各节点状态，节点可点击查看该节点对话与产物。
+8. 流程图右上角提供“查看”按钮，打开弹窗展示更完整的业务链流程图。
+9. 当业务链中所有岗位产物都处于有效已交付状态后，开放“方案总结”。
+10. 方案总结完成后开放“行动规划”。
+11. 即使进入方案总结或行动规划，用户仍可返回产物列表执行驳回。
+12. 若驳回早期阶段产物，后续阶段产物、方案总结、行动规划都一起失效并回到待重新完成状态。
+
+## 2. 状态设计
+
+### 2.1 节点状态
+
+现有节点状态需要扩展或映射为更贴近页面的展示状态：
+
+| 展示状态 | 建议内部状态 | 含义 |
+| --- | --- | --- |
+| 未完成 | `ready` / `locked` / `rejected` | 尚未有效交付，或被驳回后等待重做 |
+| 进行中 | `running` | 当前智能体正在回答或产物正在生成 |
+| 已完成 | `done` | 当前节点已有有效交付 |
+| 已失效 | `stale` | 上游被更新或驳回，当前结果不可作为最终材料 |
+| 异常 | `error` | 生成或保存失败 |
+
+建议新增 `rejected` 状态，便于区分“从未完成”和“被驳回后待重做”。如果第一轮想少改后端，也可以先用 `ready + rejection_record` 表示被驳回。
+
+### 2.2 产物状态
+
+产物状态建议独立于节点状态保存，因为一个节点可能同时有回答文本和多个文件产物。
+
+| 状态 | 含义 |
+| --- | --- |
+| `pending` | 还没有交付 |
+| `running` | 正在生成 |
+| `delivered` | 已交付且当前有效 |
+| `rejected` | 被用户驳回 |
+| `stale` | 受上游驳回或重做影响，已经失效 |
+
+### 2.3 内置收口节点
+
+在流程图中把两个内置节点追加到业务链末尾：
+
+1. `builtin:summary`：方案总结智能体。
+2. `builtin:action-plan`：行动规划智能体。
+
+这两个节点不属于普通业务链席位，但要和普通节点一样显示状态、支持点击查看结果。
+
+## 3. 数据模型调整
+
+### 3.1 Session 扩展
+
+`position_roundtable_sessions` 已使用下列持久化字段：
+
+| 字段 | 含义 |
+| --- | --- |
+| `status` | `intent_pending / active / completed / archived`；总结/规划运行态由前端瞬时状态与对应快照的 `status` 表示，避免一次运行中断后留下伪运行态 |
+| `summary_thread_id` | 方案总结智能体线程 |
+| `summary_snapshot` | 最新有效总结报告快照 |
+| `action_plan_thread_id` | 行动规划智能体线程 |
+| `action_plan_snapshot` | 最新有效行动规划快照 |
+| `invalidated_at` | 记录在 `summary_snapshot` / `action_plan_snapshot` 内，包含 `invalidated_by`，无需重复写 Session 字段 |
+
+### 3.2 Node 扩展
+
+`position_roundtable_nodes` 已使用下列字段（展示状态由前端按状态映射）：
+
+| 字段 | 含义 |
+| --- | --- |
+| `status` | `locked / ready / running / done / stale / rejected / error`，前端直接映射为展示状态 |
+| `rejection_count` | 当前节点累计驳回次数 |
+| `last_rejection` | 最新驳回标题、理由、操作者、时间 |
+| `revision` | 当前有效交付版本 |
+| `invalidated_by` | 导致当前节点失效的上游节点 key |
+
+### 3.3 Deliverable 新表（后续可选）
+
+当需要“单个文件独立驳回、跨会话检索或完整版本对比”时，再新增 `position_roundtable_deliverables`，不要只依赖 `artifact_manifest`。
+
+| 字段 | 含义 |
+| --- | --- |
+| `id` | 产物 ID |
+| `session_id` | 会话 ID |
+| `node_key` | 来源节点 |
+| `agent_id` | 来源智能体 |
+| `position_id` | 来源岗位 |
+| `title` | 产物名称 |
+| `kind` | `answer / file / summary / action_plan` |
+| `content` | 文本产物内容摘要或正文 |
+| `artifact_path` | 文件产物虚拟路径 |
+| `thread_id` | 所属线程 |
+| `status` | `pending / running / delivered / rejected / stale` |
+| `revision` | 来源节点版本 |
+| `rejection_title` | 驳回标题 |
+| `rejection_reason` | 驳回理由 |
+| `created_at` | 创建时间 |
+| `updated_at` | 更新时间 |
+
+当前第一轮不新增这张表：右侧产物卡片、驳回记录、总结输入材料从节点 `artifact_manifest`、节点版本/驳回记录和 Session 快照聚合，避免节点表与产物表双写。后续引入该表时，应把它提升为唯一事实来源，而不是并行维护两套状态。
+
+## 4. 驳回与级联失效规则
+
+### 4.1 基本驳回
+
+用户点击产物卡片的“驳回”后弹窗填写：
+
+- 驳回标题。
+- 驳回理由。
+
+提交后：
+
+- 当前产物状态改为 `rejected`。
+- 当前节点状态改为 `rejected` 或 `ready`。
+- 当前节点的 `latest_answer` 和历史文件不删除，但不再作为有效交付输入。
+- 记录 `last_rejection`，用于页面展示和后续追踪。
+
+### 4.2 级联失效
+
+如果驳回的节点位于第 N 阶段：
+
+- 同阶段其他节点不自动驳回，除非业务链未来明确配置了依赖关系。
+- 第 N+1 阶段及之后所有节点的有效产物全部标记为 `stale`。
+- 后续节点状态回到未完成展示态。
+- `builtin:summary` 和 `builtin:action-plan` 如果已经生成，也标记为 `stale`。
+- 页面允许用户继续查看旧报告和旧行动规划，但必须提示“上游产物已变更，需要重新生成”。
+
+### 4.3 重新交付
+
+被驳回节点重新问答并完成后：
+
+- 当前节点产生新的 `revision`。
+- 当前节点产物状态变为 `delivered`。
+- 只有当该阶段所有必要节点都重新有效交付后，下一阶段才重新解锁。
+- 方案总结和行动规划必须基于最新有效产物重新生成。
+
+## 5. 接口规划
+
+### 5.1 启动与校验
+
+| 方法 | 路径 | 用途 |
+| --- | --- | --- |
+| `POST` | `/api/position-roundtable/sessions/{id}/validate-activation` | 校验业务链、岗位、智能体、意图状态 |
+| `POST` | `/api/position-roundtable/sessions/{id}/activate` | 校验通过后冻结链条并初始化节点 |
+
+第一轮也可以先把校验合并在 `activate` 内，前端根据后端返回的错误码提示。
+
+### 5.2 产物
+
+| 方法 | 路径 | 用途 |
+| --- | --- | --- |
+| `GET` | `/api/position-roundtable/sessions/{id}/results` | 获取右侧统一产物来源节点（前端聚合文件与内置快照） |
+| `GET` | `/api/position-roundtable/sessions/{id}/nodes/{node_key}` | 获取节点详情；文件正文由既有线程产物预览接口读取 |
+| `POST` | `/api/position-roundtable/sessions/{id}/nodes/{node_key}/reject` | 驳回当前节点交付并触发级联失效 |
+| `POST` | `/api/position-roundtable/sessions/{id}/nodes/{node_key}/complete-turn` | 节点回答结束后同步回答与产物 |
+
+### 5.3 方案总结与行动规划
+
+| 方法 | 路径 | 用途 |
+| --- | --- | --- |
+| `POST` | `/api/position-roundtable/sessions/{id}/summary/prepare` | 服务端准备版本锁定的总结材料和线程信息 |
+| `POST` | `/api/position-roundtable/sessions/{id}/summary/ask` | 服务端准备总结的同线程续问材料 |
+| `POST` | `/api/position-roundtable/sessions/{id}/summary/complete` | 校验 Markdown 交付与来源版本后持久化总结快照 |
+| `POST` | `/api/position-roundtable/sessions/{id}/action-plan/prepare` | 服务端准备行动规划材料和线程信息 |
+| `POST` | `/api/position-roundtable/sessions/{id}/action-plan/ask` | 服务端准备行动规划同线程续问材料 |
+| `POST` | `/api/position-roundtable/sessions/{id}/action-plan/complete` | 校验 Markdown + JSON 交付与来源版本后持久化行动规划快照 |
+
+可以复用现有 `streamMultiAgent` 流式协议，但建议在岗位会商下包一层 API，由后端负责拼装岗位会商材料，前端不直接拼长 prompt。
+
+## 6. 前端实施步骤
+
+### 阶段 1：状态与启动校验（已完成）
+
+- 扩展 `PositionNodeStatus` 和状态显示映射。
+- “确认意图并启动业务链”前补齐校验提示。
+- 后端 `activate` 返回未配置岗位、缺智能体、未选择链条等具体错误。
+- 左侧流程图节点右上角添加状态小图标。
+- 节点样式调整为上方智能体名称、下方岗位名称，移除左侧 logo。
+
+验收标准：未选择业务链、岗位未配齐、意图未完成时都能准确阻止启动；启动后流程图能显示各节点状态。
+
+### 阶段 2：流程图弹窗（已完成）
+
+- 左侧保留小型从上到下流程图。
+- 流程图右上角增加“查看”按钮。
+- 点击后打开弹窗，展示更大的流程图。
+- 弹窗内支持点击节点查看对话与产物，保持和主页面选中节点同步。
+
+验收标准：小图不挤占左侧空间，大图能完整展示业务链和两个内置收口节点。
+
+### 阶段 3：产物卡片与预览（已完成）
+
+- 右侧新增或改造“分析结果”Tab 为“交付产物”列表。
+- 卡片展示智能体名称、产物名称、岗位名称、时间、状态。
+- 点击卡片打开详情弹窗。
+- 文本产物直接展示正文，文件产物复用现有 `ArtifactPreviewModal`。
+- 每个有效产物提供“驳回”入口。
+
+验收标准：节点回答和文件产物能进入统一产物列表；点击可查看详情。
+
+### 阶段 4：驳回弹窗与级联失效（已完成）
+
+- 新增 `RejectDeliverableDialog`。
+- 驳回表单包含标题和理由，均必填。
+- 后端事务内完成当前产物驳回、当前节点状态更新、后续阶段级联失效、总结和行动规划失效。
+- 前端刷新 Session、Node、Deliverable 和流程图状态。
+- 被驳回节点在对话区显示驳回信息，提示用户重新交付。
+
+验收标准：驳回第一阶段任意节点后，第二阶段及之后产物都显示未完成或已失效；旧内容可查看但不能作为总结输入。
+
+### 阶段 5：方案总结智能体（已完成）
+
+- 封装 `usePositionSummary`，内部复用 `roundtable-summary` 的线程初始化、流式输出和 Markdown 产物预览能力。
+- 输入材料改为岗位会商材料：
+  - 任务信息。
+  - 情报分析岗意图结果。
+  - 业务链快照。
+  - 所有状态为 `delivered` 的岗位产物。
+  - 已驳回或失效产物只作为历史参考，不进入默认总结材料。
+- 方案总结节点追加到流程图末尾。
+- 所有产物有效交付后才允许点击“生成方案总结”。
+- 总结结果写入 `summary_snapshot`，同时进入产物列表。
+
+验收标准：总结报告使用现有方案总结能力生成 Markdown；刷新页面后可恢复；上游驳回后总结标记失效。
+
+### 阶段 6：行动规划智能体（已完成）
+
+- 新增内置智能体 ID，建议先命名为 `position-action-planner`。
+- 新增行动规划 prompt：
+  - 读取方案总结报告。
+  - 读取各岗位最终有效产物。
+  - 拆解为若干子任务。
+  - 每个子任务包含名称、目标、输入依据、责任岗位建议、前置依赖、交付物、验收标准。
+- 输出两类产物：
+  - `行动规划报告.md`。
+  - `action-plan-subtasks.json`。
+- 行动规划节点追加到方案总结之后。
+- 方案总结有效完成后才允许启动行动规划。
+
+验收标准：行动规划能生成可读报告和结构化子任务；刷新可恢复；上游驳回后自动失效。
+
+### 阶段 7：返回修改与重新生成（已完成）
+
+- 用户在方案总结或行动规划视图中仍可切回“交付产物”。
+- 驳回后自动显示需要重做的节点。
+- 重做节点完成后，允许重新生成方案总结和行动规划。
+- 旧总结、旧行动规划保留历史查看，但状态显示“已失效”。
+
+验收标准：不会因为进入总结/规划阶段而锁死前序产物；前序重做后能形成新版本闭环。
+
+### 阶段 8：测试与回归（已完成）
+
+- 后端测试：
+  - activate 校验。
+  - 节点完成后产物入库。
+  - 驳回当前节点。
+  - 驳回第一阶段时后续阶段级联失效。
+  - 总结和行动规划失效。
+- 前端测试：
+  - 启动校验提示。
+  - 状态图标显示。
+  - 产物卡片筛选和预览。
+  - 驳回弹窗必填校验。
+- 回归验证：
+  - 原多智能体会商页面不受影响。
+  - 业务链普通配置入口不显示岗位配置。
+  - 岗位会商页面刷新恢复正常。
+  - 深色模式和嵌入模式布局不溢出。
+
+## 7. 推荐提交拆分
+
+1. `feat(position-roundtable): add delivery status model`
+2. `feat(position-roundtable): validate chain activation`
+3. `feat(position-roundtable): add workflow status graph`
+4. `feat(position-roundtable): add deliverable cards and preview`
+5. `feat(position-roundtable): support rejection cascade`
+6. `feat(position-roundtable): add summary builtin node`
+7. `feat(position-roundtable): add action planning builtin node`
+8. `test(position-roundtable): cover delivery workflow`
+
+## 8. 第一轮建议范围
+
+第一轮优先做最小可闭环：
+
+```text
+意图识别
+→ 启动校验
+→ 业务链节点状态
+→ 节点产物列表
+→ 产物详情查看
+→ 驳回与级联失效
+→ 全部交付后生成方案总结
+→ 基于总结生成行动规划
+```
+
+如果时间紧，行动规划可以先生成 Markdown 报告，结构化 `subtasks.json` 放到第二轮；但数据模型和 UI 入口第一轮就要预留，否则后面会返工。

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

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

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

+
+## 17. 关键代码索引
+
+| 主题 | 位置 |
+| --- | --- |
+| 临时名 / 完整扩展名 / latestStreamingWriteFile | `PositionNodeChat.tsx` 中 `provisionalWriteFilePath`、`hasCompleteArtifactExtension`、`latestStreamingWriteFile` |
+| armed / baseline / 上报 effect | `PositionNodeChat.tsx` `handleSubmit` + streaming preview `useEffect` |
+| 同 tool call 判断 / 二次写入重挂 | 同上，`isSameToolCall` / `previewKey` |
+| 线程绑定保护 | `PositionNodeChat.tsx` node binding `useEffect` 中 `isOwnThreadBinding` |
+| sandboxCloseKey / store / 前沿节流 | `PositionRoundtablePage.tsx` `sandboxCloseKey`、`createSandboxThreadStore`、`queueSandboxThreadSnapshot` |
+| 打开 / path upgrade / 抑制 | `PositionRoundtablePage.tsx` `handlePreviewArtifact` |
+| 关闭 | `PositionRoundtablePage.tsx` `closeSandbox` |
+| 虚拟 URL 读 content | `core/artifacts/loader.ts` `loadArtifactContentFromToolCall` |
+| 源码/预览切换 | `artifact-file-detail.tsx` 中 `viewMode` + `thread.isLoading` |
+| 普通页步骤条自动开 | `message-group.tsx` `write_file` 分支 |
+
+相关提交（背景）：
+
+- `fix(frontend): 岗位会商沙箱在 write_file 流式阶段实时打开并刷新`  
+  — 临时名打开、外部 store、前沿节流  
+- `fix(frontend): 同路径二次 write_file 时重挂岗位会商沙箱`  
+  — previewKey 按 tool call，禁止按 path 复用  
+
+---
+
+## 18. 术语表
+
+| 术语 | 含义 |
+| --- | --- |
+| armed | 本轮用户发送后，允许自动打开沙箱的开关 |
+| baseline | send 前已有的 write tool call 集合，用于忽略历史产物 |
+| previewKey | 一次交付的稳定身份，推荐 `messageId:toolCallId` |
+| sandboxCloseKey | 关闭抑制键，同时用作 `ArtifactFileDetail` 的 React key |
+| provisional path / 临时名 | 尚无真实 path 时的 `未命名文件.md` / `.html` |
+| path upgrade | 同 previewKey 下临时名升级为真实 path |
+| sandboxThreadStore | 流式线程外部 store，避免整页重渲染 |
+| write-file: URL | 用 message_id + tool_call_id 定位流式 content 的虚拟路径 |
+| leading-edge throttle / 前沿节流 | 到期立即在回调里 publish，而不是只挂尾随 timer |
+| content-first / path-first | 模型流式 JSON 参数时 content 与 path 哪个先到 |
+| isOwnThreadBinding | 本节点把自己的新 threadId 写回 props，不是切节点 |
+
+---
+
+## 附录 A：给对接同学的一页纸摘要
+
+1. 页面壳只挂一个沙箱；子组件只调用 `onPreviewArtifact` / `onThreadSnapshot`。  
+2. 自动打开时机 ≈ 步骤条出现「写入文件」时，而不是出现文件名时。  
+3. `write_file` 可以没有 path：临时名打开，path 到了再改名。  
+4. 流式 thread 进外部 store，进页面 state 会卡死。  
+5. 节流要前沿；previewKey 看 tool call；关闭抑制看 sandboxCloseKey。  
+6. 同路径重新生成 = 新 previewKey = 沙箱重挂。  
+7. 出问题先对照第 13、14 节，再看代码索引第 17 节。
