+# Safe OS UI - API Gateway 路由转发规则文档
+
+本系统包含多个独立的后端AI服务（规划系统、开发平台、质量门禁等）。为了使前端统一指向单一入口并简化跨域和请求分发配置，建议使用 API Gateway 进行统一路由和负载均衡。
+
+以下是当前前端所有与后端服务交互的接口清单以及转发规则。Gateway 服务需要解析相应的路径前缀（Ingress Prefix），将请求 Rewrite 后转发至对应的内部后端服务。
+
+---
+
+## 整体架构与入口规则
+
+- **统一入口 URL**：`http://<api-gateway-host>:<port>` （前端将所有 API 请求指向此地址）
+- **核心路由匹配策略**：基于 URL前缀 进行正则匹配或前缀匹配。
+
+| 业务模块 | Ingress Prefix (外部路径) | Forward Target (内部服务地址) | Rewrite Rule (路径重写规则) |
+| --- | --- | --- | --- |
+| **Planning System** | `/planning-api/*` | `http://localhost:8090` | `/planning-api/(.*)` ➔ `/api/$1` |
+| **DevOps System** | `/devops-api/*` | `http://localhost:8000` | `/devops-api/(.*)` ➔ `/$1` |
+| **Quality Gate System** | `/quality-api/*` | `http://localhost:5000` | `/quality-api/(.*)` ➔ `/api/$1` |
+
+---
+
+## 1. 规划子系统接口 (Planning System) 
+**底层服务**: `http://localhost:8090`
+前缀重写规则：请求至统一入口 `.../planning-api/X` 会被转发至内部的 `.../api/X`。
+
+| 方法 | 外部暴露路径 (Gateway URL) | 内部转发路径 (Target URL) | 接口描述 |
+| --- | --- | --- | --- |
+| `POST` | `/planning-api/chat/stream` | `/api/chat/stream` | 铁三角 Agent：发送大系统规划/史诗业务需求内容（SSE流式数据返回） |
+| `POST` | `/planning-api/upload` | `/api/upload` | 文档上传：支持用户上传附件作为系统知识或输入来源 |
+
+---
+
+## 2. 研发自动引擎接口 (DevOps System)
+**底层服务**: `http://localhost:8000`
+前缀重写规则：请求至统一入口 `.../devops-api/X` 会被去掉前缀，转为后端的 `.../X`。该系统重度依赖**SSE (Server-Sent Events) 流式连接**，请在Gateway配置中确保不会缓冲或阻断流数据。
+
+| 方法 | 外部暴露路径 (Gateway URL) | 内部转发路径 (Target URL) | 接口描述 |
+| --- | --- | --- | --- |
+| `POST` | `/devops-api/session/start` | `/session/start` | 新建研发自动化任务会话 (Session) |
+| `POST` | `/devops-api/session/{sessionId}/clarify` | `/session/{sessionId}/clarify` | 基于需求说明进行需求澄清和补充 |
+| `GET` | `/devops-api/session/{sessionId}/pm/stream` | `/session/{sessionId}/pm/stream` | PM角色执行需求细化分析流程 (SSE流) |
+| `GET` | `/devops-api/session/{sessionId}/pm/refine/stream` | `/session/{sessionId}/pm/refine/stream` | 追加PM反馈，继续流式提炼需求 (SSE流) |
+| `GET` | `/devops-api/session/{sessionId}/qa/stream` | `/session/{sessionId}/qa/stream` | QA角色基于需求生成测试用例并执行评估 (SSE流) |
+| `GET` | `/devops-api/session/{sessionId}/qa/refine/stream` | `/session/{sessionId}/qa/refine/stream` | 追加QA用例反馈并更新测试集 (SSE流) |
+| `GET` | `/devops-api/session/{sessionId}/dev/stream` | `/session/{sessionId}/dev/stream` | 核心编码过程：依据需求、架构与测试生成最终业务/Java等工程代码 (SSE流) |
+| `POST` | `/devops-api/session/{sessionId}/test/run` | `/session/{sessionId}/test/run` | 运行集成编译与单元/端到端测试并获取结果 |
+| `GET` | `/devops-api/session/{sessionId}/test/fix/stream` | `/session/{sessionId}/test/fix/stream` | 针对测试错误进行的AI代码自动修复 (SSE流) |
+
+*注意： `{sessionId}` 属于路径层级中的动态参数，具体网关转发时使用泛类型或通配符放行。*
+
+---
+
+## 3. 代码质量门禁接口 (Quality Gate)
+**底层服务**: `http://localhost:5000`
+前缀重写规则：请求至统一入口 `.../quality-api/X` 会被转发至后端内部的 `.../api/X`。
+
+| 方法 | 外部暴露路径 (Gateway URL) | 内部转发路径 (Target URL) | 接口描述 |
+| --- | --- | --- | --- |
+| `GET` | `/quality-api/prs` | `/api/prs` | 获取 PR 扫描工单列表（支持多种查询参数） |
+| `GET` | `/quality-api/prs/history` | `/api/prs/history` | 获取 PR 处理历史，用于趋势看板 (e.g., `?limit=15`) |
+| `GET` | `/quality-api/prs/{prId}` | `/api/prs/{prId}` | 获取某一条指定 PR 扫描记录的详细执行状态及摘要 |
+| `GET` | `/quality-api/prs/{prId}/files` | `/api/prs/{prId}/files` | 拉取这条 PR 的被影响/改动的文件目录结构 |
+| `GET` | `/quality-api/prs/{prId}/file` | `/api/prs/{prId}/file` | 获取PR里指定文件的 Diff 对象（包含行内审查反馈），附带 `?path=xxx` 查询参数 |
+| `POST`| `/quality-api/prs/{prId}/merge` | `/api/prs/{prId}/merge` | 在门禁界面确认问题修缮无误后，合并该次 PR |
+| `POST`| `/quality-api/prs/{prId}/close` | `/api/prs/{prId}/close` | 门禁审查不通过，拒绝/关闭此条扫描和合并申请 |
+

+
+## Nginx Gateway 配置示例 (参考)
+
+如果网关选用 Nginx，可快速参考如下配置来完成上述 Rewrite 与 Proxy：
+
+```nginx
+server {
+    listen 80;
+    server_name api-gateway.safe-os.local;
+
+    # 1. Planning API 转发
+    location /planning-api/ {
+        # 截取 /planning-api/ 后的内容，拼接到 /api/
+        rewrite ^/planning-api/(.*)$ /api/$1 break;
+        proxy_pass http://localhost:8090;
+        
+        # 启用流连接所需的头信息
+        proxy_set_header Connection '';
+        proxy_http_version 1.1;
+        chunked_transfer_encoding off;
+        proxy_buffering off;
+        proxy_cache off;
+    }
+
+    # 2. DevOps API 转发
+    location /devops-api/ {
+        # 截取 /devops-api/ 后的内容，直接拼接
+        rewrite ^/devops-api/(.*)$ /$1 break;
+        proxy_pass http://localhost:8000;
+
+        # 支撑 SSE (Server-Sent Events) 的流配置
+        proxy_set_header Connection '';
+        proxy_http_version 1.1;
+        chunked_transfer_encoding off;
+        proxy_buffering off;
+        proxy_cache off;
+        proxy_read_timeout 3600s; # 考虑大模型生成代码时间较长
+    }
+
+    # 3. Quality Gate API 转发
+    location /quality-api/ {
+        # 截取 /quality-api/ 后的内容，拼接到 /api/
+        rewrite ^/quality-api/(.*)$ /api/$1 break;
+        proxy_pass http://localhost:5000;
+    }
+}
+```
+
+以上文档即针对前端当前服务现状所整理的 API Gateway 路由规划规范，您可以直接根据此规范开发 API Gateway 或调整 Nginx 等负载均衡器的配置。

+# Vibe Coding Design Docs: Workspace/Artifact Split-Screen Pattern
+
+## 1. Context & Objective
+The goal is to implement a UI/UX pattern similar to **Claude Artifacts** or **Gemini Deep Research**. When a specific complex task is triggered (e.g., "Project Planning Skill"), the single-column chat interface should smoothly transition into a split-screen layout:
+- **Left Panel (35%)**: Conversational context, CoT (Chain of Thought) traces, tool calls, and user input.
+- **Right Panel (65%)**: A dedicated "Workspace" or "Artifact" rendering area to display long-form content (Markdown, code, diagrams) generated by the Agent's skills.
+
+Crucially, this system must support **Reflexion/Iterative generation**. The user can comment on the generated artifact in the left panel, and the agent should update the artifact in the right panel based on the feedback.
+
+---
+
+## 2. Frontend Implementation Guide (React + Vite + Tailwind)
+
+### 2.1 State Management (State & Types)
+Extend the existing frontend state to track the workspace status and content.
+
+```typescript
+// 1. Extend the StreamEvent type to support UI control and artifact streaming
+type StreamEvent = {
+  type: 
+    | "thought" 
+    | "tool_call" 
+    | "tool_result" 
+    | "message"          // Standard chat message
+    | "error"
+    | "workspace_start"  // Trigger right panel open
+    | "workspace_delta"  // Streaming text for the right panel
+    | "workspace_end";   // Streaming completed
+  content: string;
+  step?: number;
+  tool_name?: string;
+  workspace_title?: string; // Optional title for the artifact
+};
+
+// 2. Add Workspace State (Can be added to useReducer or a separate useState)
+type WorkspaceState = {
+  isOpen: boolean;
+  title: string;
+  content: string;
+  isGenerating: boolean;
+};
+```
+
+### 2.2 SSE Parsing Logic
+Modify the `onEvent` handler inside `streamChat` to intercept `workspace_*` events.
+- When `workspace_start` arrives: Set `workspace.isOpen = true`, clear previous content, set `isGenerating = true`.
+- When `workspace_delta` arrives: Append text to `workspace.content`. Do **not** append this text to the left-panel chat history to avoid redundancy.
+- When `workspace_end` arrives: Set `isGenerating = false`.
+
+### 2.3 Layout & UI Re-architecture
+Refactor the root `<div>` of `PlanningAgent.tsx` to handle dynamic flex layouts. Use Tailwind's transition utilities for smooth scaling.
+
+```tsx
+<div className="flex h-full w-full overflow-hidden bg-surface">
+  
+  {/* Left Panel: Chat & Controls */}
+  <div 
+    className={`flex flex-col h-full transition-all duration-300 ease-in-out ${
+      workspace.isOpen ? 'w-[35%] border-r border-border min-w-[350px]' : 'w-full max-w-5xl mx-auto'
+    }`}
+  >
+      {/* Existing Message List & Input Area */}
+  </div>
+
+  {/* Right Panel: Workspace / Deep Research Output */}
+  {workspace.isOpen && (
+    <div className="w-[65%] h-full flex flex-col bg-surface-muted transition-opacity duration-300 animate-fade-in">
+       {/* Header */}
+       <div className="h-14 border-b border-border flex items-center px-6 justify-between bg-white">
+          <h3 className="font-semibold text-txt flex items-center gap-2">
+            <IconDocument /> {workspace.title || 'Project Planning Document'}
+          </h3>
+          {workspace.isGenerating && (
+             <span className="text-sm text-magenta animate-pulse flex items-center gap-1">
+               <Spinner /> Generating...
+             </span>
+          )}
+       </div>
+       {/* Markdown Content Area */}
+       <div className="flex-1 overflow-y-auto p-8 prose prose-slate max-w-none">
+          <ReactMarkdown remarkPlugins={[remarkGfm]} rehypePlugins={[rehypeRaw]}>
+            {workspace.content}
+          </ReactMarkdown>
+       </div>
+    </div>
+  )}
+</div>
+```
+
+---
+
+## 3. Backend Implementation Guide (Agent / ReAct Loop)
+
+The backend agent requires structural changes to understand the "Artifact" concept, emit correct SSE events, and maintain the artifact in its memory for iterative edits.
+
+### 3.1 Tool / Skill Definition
+When defining the `Project Planning Skill` for the LLM, clearly state its output behavior so the LLM knows *when* to use it.
+- **Tool Description**: `use_planning_workspace`: "Invoke this tool to generate, structure, or update a major project planning document. The output will be rendered in a dedicated UI workspace."
+
+### 3.2 Context Injection (Memory for Reflexion)
+To allow the user to say *"extend the testing phase to 2 weeks"*, the LLM **must know what is currently in the right panel**.
+- **Before sending the prompt to the LLM**, query the database/session for the current Artifact state.
+- **Prompt Assembly**:
+  ```text
+  [System Prompt / ReAct Instructions]
+  ...
+  
+  [Current Workspace Artifact (if exists)]
+  <workspace>
+  # Project Plan
+  1. Dev Phase: 1 week
+  2. Testing Phase: 1 week
+  </workspace>
+
+  [Chat History]
+  User: extend the testing phase to 2 weeks.
+  ```
+
+### 3.3 Streaming Control (Hijacking the Stream)
+Within the ReAct execution loop, when the Agent decides to execute the `Project Planning Skill`:
+1. The Backend normally streams `thought` or `tool_call` events.
+2. Upon entering the specific Skill execution, the backend emits `{"type": "workspace_start", "workspace_title": "Update: Project Plan"}`.
+3. As the LLM (or a sub-agent) generates the Markdown schema, the backend maps these tokens to `workspace_delta` events and flushes them to the frontend.
+4. (CRITICAL) Do **not** send these tokens as `message` or `final` chat events. The chat bubble should only say something like: *"I have updated the project plan in the workspace area."*
+5. Save the final generated Markdown text into the session memory as the `Current Artifact` for future context injection.
+
+---
+
+## 4. Work Flow Summary (For LLM context generation)
+
+1. `User` sends prompt: "Plan the new feature".
+2. `Agent` thinks (`type: thought`), decides to use `Project Planning Skill` (`type: tool_call`).
+3. `Agent` emits `{"type": "workspace_start"}`.
+4. `Frontend` expands right panel (65% width).
+5. `Agent` streams `{"type": "workspace_delta", "content": "..."}`.
+6. `Frontend` live-renders Markdown in the right panel.
+7. `Agent` finishes, saves artifact to backend session.
+8. `User` reads right panel, types in left panel: "Change point 2".
+9. `Agent` receives Left Panel history + Right Panel Artifact Content.
+10. `Agent` updates document, streaming new `workspace_delta`. Frontend live-updates the right panel.

+# WebUI `/api/chat/stream` 前端对接说明
+
+本文档用于指导前端项目接入 LaodingBot 的流式聊天接口，并可直接作为提示词输入给 LLM，批量改造其他前端代码。
+
+## 1. 接口总览
+
+- 方法: `POST`
+- 路径: `/api/chat/stream`
+- 请求头: `Content-Type: application/json`
+- 响应类型: `text/event-stream`
+- 协议: SSE (Server-Sent Events)
+
+说明: 该接口为单次请求、多次推送。后端会持续推送 `data: <json>\n\n` 格式的事件。
+
+## 2. 请求体
+
+```json
+{
+  "text": "请帮我分析当前目录",
+  "session_id": "sess_abc",
+  "user_id": "user_001"
+}
+```
+
+字段说明:
+
+- `text` (string, required): 用户输入文本，去除空白后不能为空。
+- `session_id` (string, optional): 会话 ID，不传时后端自动生成。
+- `user_id` (string, optional): 用户 ID，不传时后端自动生成。
+
+兼容字段:
+
+- `sessionId` 等价于 `session_id`
+- `userId` 等价于 `user_id`
+
+## 3. SSE 事件格式
+
+每条 SSE 消息只包含 `data` 字段，内容是 JSON:
+
+```text
+data: {"type":"thought","content":"我先判断是否需要调用工具","step":1}
+
+data: {"type":"tool_call","content":"{\"input\":\"pwd\"}","step":1,"tool_name":"shell"}
+
+data: {"type":"tool_result","content":"C:/Project/MyProject","step":1,"tool_name":"shell"}
+
+data: {"type":"final","content":"当前目录是 C:/Project/MyProject","step":2}
+
+```
+
+事件字段:
+
+- `type` (string): 事件类型
+- `content` (string): 事件文本内容
+- `step` (number, optional): ReAct 步骤编号
+- `tool_name` (string, optional): 工具名
+
+事件类型:
+
+- `thought`: LLM 思考片段（可选透传）
+- `tool_call`: 工具调用请求（可选透传）
+- `tool_result`: 工具执行结果（可选透传）
+- `final`: 最终回答
+- `error`: 错误信息
+
+说明:
+
+- 默认情况下（`WEBUI_EXPOSE_REASONING=false`），WebUI 只向前端返回 `final` 和 `error`。
+- 当设置 `WEBUI_EXPOSE_REASONING=true` 时，WebUI 会额外透传 `thought`、`tool_call`、`tool_result` 事件。
+- 无论是否透传推理事件，`final` 都会分段累计推送，以便前端实现打字机效果。
+
+## 4. 连接生命周期
+
+- 正常结束: 收到 `type=final` 后结束渲染，连接可由浏览器自然关闭。
+- 异常结束: 收到 `type=error`，前端应显示错误并结束当前轮次。
+- 网络中断: 前端应允许用户重试，并保留已收到的事件记录。
+
+## 5. 前端渲染建议
+
+推荐前端仅处理两类结果:
+
+- 答案区: 显示最后一个 `final`
+- 错误区: 显示 `error`
+
+如果开启了 `WEBUI_EXPOSE_REASONING=true`，建议额外提供“思考面板”：
+
+- 思考区: 渲染 `thought`
+- 工具区: 渲染 `tool_call` / `tool_result`
+
+建议状态机:
+
+- `idle`: 初始状态
+- `streaming`: 请求中且持续接收事件
+- `done`: 收到 `final`
+- `failed`: 收到 `error` 或请求异常
+
+## 6. TypeScript 对接示例 (fetch + ReadableStream)
+
+```ts
+type StreamEventType = 'thought' | 'tool_call' | 'tool_result' | 'final' | 'error';
+
+interface StreamEvent {
+  type: StreamEventType;
+  content: string;
+  step?: number;
+  tool_name?: string;
+}
+
+export async function streamChat(
+  payload: { text: string; session_id?: string; user_id?: string },
+  onEvent: (event: StreamEvent) => void,
+  signal?: AbortSignal,
+): Promise<void> {
+  const resp = await fetch('/api/chat/stream', {
+    method: 'POST',
+    headers: { 'Content-Type': 'application/json' },
+    body: JSON.stringify(payload),
+    signal,
+  });
+
+  if (!resp.ok) {
+    throw new Error(`HTTP ${resp.status}`);
+  }
+  if (!resp.body) {
+    throw new Error('ReadableStream is not available');
+  }
+
+  const reader = resp.body.getReader();
+  const decoder = new TextDecoder('utf-8');
+  let buffer = '';
+
+  while (true) {
+    const { value, done } = await reader.read();
+    if (done) break;
+
+    buffer += decoder.decode(value, { stream: true });
+
+    // SSE message delimiter: blank line
+    let idx = buffer.indexOf('\n\n');
+    while (idx >= 0) {
+      const chunk = buffer.slice(0, idx).trim();
+      buffer = buffer.slice(idx + 2);
+
+      for (const line of chunk.split('\n')) {
+        const text = line.trim();
+        if (!text.startsWith('data:')) continue;
+        const raw = text.slice(5).trim();

+
+## 7. 给 LLM 的改造任务提示词模板
+
+将下面模板发给 LLM，可用于自动改造其他前端项目:
+
+```text
+你要改造一个前端项目的聊天页面，把非流式接口 `/api/chat` 改为流式接口 `/api/chat/stream`。
+
+后端协议约束:
+1) 请求方法 POST，Content-Type=application/json
+2) 请求体: { text, session_id?, user_id? }
+3) 响应是 SSE 文本流，事件格式为 `data: <json>\n\n`
+4) JSON 结构:
+   - type: thought | tool_call | tool_result | final | error
+   - content: string
+   - step?: number
+   - tool_name?: string
+5) 收到 final 视为本轮完成；收到 error 视为失败
+6) 默认不要假设前端一定会收到 thought/tool_call/tool_result；仅当 `WEBUI_EXPOSE_REASONING=true` 才会透传
+
+你的改造要求:
+1) 保留现有 UI 风格和组件结构，不做无关重构
+2) 新增流式读取逻辑，支持中途取消 (AbortController)
+3) 将事件按 step 渲染到消息区
+4) 兼容旧会话字段命名 (session_id / sessionId, user_id / userId)
+5) 增加错误态与重试按钮
+6) 不破坏原有上传、历史消息和输入框行为
+7) 输出改动文件列表 + 每个文件的关键变更说明
+
+请直接给出可运行代码补丁。
+```
+
+## 8. 调试清单
+
+- 检查响应头是否为 `text/event-stream`
+- 检查每条事件是否以 `data:` 开头并以空行结尾
+- 确认 `final` 和 `error` 都能正确结束当前轮次
+- 验证弱网下不会丢失已收到的事件
+- 验证用户快速连续提问时，旧流可被取消

+
+## 业务背景
+目前我们接入云端的 50 万台新能源车辆中，电池因单体压差过大导致的突发性故障率有上升趋势，造成了较高的售后索赔成本和用户客诉。我们需要在 Q3 PI (Program Increment) 落地一套“电池预测性维护系统”。
+
+## 核心目标
+1. **数据实时采集**：云端需要能够高频接收车辆上报的电池运行遥测数据（包含单体电压、温度、充放电电流等）。
+2. **云端 AI 分析**：利用云端的 AI 异常检测模型，对电池数据进行实时流式计算，预测未来 7 天内可能发生故障的电池包。
+3. **多端预警联动**：一旦云端判定存在高风险，需立即向车机端（座舱屏幕）和车主的手机 App 同时下发告警弹窗，并生成一条云端售后维修建议工单。
+
+## 约束与期望
+- **合规性**：采集的车辆 VIN 码和位置信息必须符合个人信息保护法（PIPL）的数据脱敏要求。
+- **性能**：云端必须能扛住 50 万台车同时在线高频上报数据的并发压力。告警下发延迟不能超过 3 秒。`)}
