2. 双部署模式架构

2.1 Pipe Mode (STDIO) — 传统嵌入模式

sequenceDiagram
    participant Host as 浏览器宿主 (Chromium)
    participant Pipe as StdioTransport
    participant MAC as MAC Policy
    participant Agent as Agent / TaskRunner
    participant ZC as ZeroClaw Runtime
    participant Backend as PipeBrowserBackend
    participant Tool as BrowserPipeTool
    participant HostExec as 宿主 Command 执行器

    Note over Host,HostExec: Pipe Mode: 一问一答式 STDIO

    Host->>Pipe: Init {version, hmac_seed, capabilities}
    Pipe->>Pipe: derive_session_key(hmac_seed)
    Pipe-->>Host: InitAck {version, agent_id, supported_actions}

    Host->>Agent: SubmitTask {instruction, page_url, page_title}
    Agent->>Agent: resolve_submit_instruction()
    alt deterministic_submit (如 线损。。。)
        Agent->>Agent: 生成 DeterministicExecutionPlan
        Agent->>Tool: execute_browser_script_skill_raw_output
    else 通用 LLM 驱动
        Agent->>ZC: 构造 ZeroClaw Agent
        ZC->>Tool: tool loop: browser_action
    end

    Tool->>MAC: validate(domain, action)
    MAC-->>Tool: allow / deny

    Tool->>Backend: invoke(action, params)
    Backend->>Pipe: AgentMessage::Command {seq, action, params, hmac}
    Pipe-->>Host: stdout: Command JSON

    Host->>HostExec: 执行浏览器命令
    HostExec-->>Host: 执行结果
    Host->>Pipe: BrowserMessage::Response {seq, success, data}
    Pipe-->>Backend: Response 回包
    Backend-->>Tool: CommandOutput
    Tool-->>ZC: ToolResult
    ZC-->>Agent: tool loop 继续或完成
    Agent-->>Host: TaskComplete {success, summary}

2.2 Service Mode (TCP + WebSocket) — 独立服务模式

sequenceDiagram
    participant Console as 前端控制台 (浏览器)
    participant WSS as WebSocket Server<br/>(127.0.0.1:42321)
    participant Agent as Agent / TaskRunner
    participant Callback as BrowserCallbackBackend
    participant HTTP as Callback HTTP Server<br/>(127.0.0.1:17888)
    participant Helper as Helper Page<br/>(浏览器内嵌辅助页)
    participant Target as 目标业务页面

    Note over Console,Target: Service Mode: 持久化服务 + Helper Page 桥接

    Console->>WSS: WebSocket Connect
    WSS->>Callback: 创建会话

    Console->>WSS: ClientMessage::SubmitTask
    WSS->>Agent: 分发任务
    Agent->>Callback: BrowserBackend::invoke()

    callback Backend 内部流程:
    Callback->>Helper: 通过 HTTP Server 推送 Command
    Helper->>Target: sgBrowserExcuteJsCodeByDomain<br/>在目标域执行 JS

    Target-->>Helper: callBackJsToCpp / XHR POST
    Helper->>HTTP: POST /sgclaw/callback/events
    HTTP-->>Callback: Callback 事件回传

    Callback-->>Agent: CommandOutput
    Agent-->>WSS: ServiceMessage::TaskComplete
    WSS-->>Console: WebSocket 推送结果
