+### Publishing to Gitea npm Registry
+
+All public `@uncaged/*` packages are published to the Gitea npm registry at `git.shazhou.work`. Workflow workspaces consume packages from this registry via `bunfig.toml`.
+
+```bash
+# Publish all packages (bun pm pack resolves workspace:* → actual versions)
+bun run publish:gitea
+
+# Dry run — see what would be published
+bun run publish:gitea:dry
+```
+
+Prerequisites: `.npmrc` in monorepo root with Gitea auth token (`//git.shazhou.work/api/packages/shazhou/npm/:_authToken=<token>`).
+
+### Workflow Workspace Setup
+
+External workflow repos (e.g. `xingyue-workflows`) use the Gitea registry for `@uncaged/*` packages. Add a `bunfig.toml`:
+
+```toml
+[install.scopes]
+"@uncaged" = "https://git.shazhou.work/api/packages/shazhou/npm/"
+```
+
+Then `bun install` resolves `@uncaged/*` from Gitea, all other packages from npmjs.
+
+### Cross-repo Development (bun link)
+
+Alternative for development against un-published local changes:
+
+```bash
+bun run link            # Register all packages (from monorepo root)
+bun run link:consume    # Link into CWD's project (⚠️ don't bun install after)
+bun run link:unlink     # Restore original deps
+```
+
+### End-to-end: Monorepo → Registry → Workspace → Bundle
+
+The recommended development flow for building workflows:
+
+```
+workflow/ (monorepo)           — engine, runtime, templates, agents
+  │  bun run publish:gitea     — auto topo-sort, bun pm pack → npm publish
+  ▼
+git.shazhou.work npm registry  — @uncaged/* scoped packages
+  │  bun install               — via bunfig.toml scoped registry
+  ▼
+my-workflows/ (workspace)     — bunfig.toml + normal package.json
+  │  bun run build:develop     — bun build → single .esm.js
+  ▼
+uncaged-workflow workflow add  — register bundle locally
+uncaged-workflow run           — execute workflow
+```
+
+1. **Monorepo changes** → `bun run publish:gitea` (packages auto-discovered from `packages/*/`, topologically sorted, `workspace:*` resolved to real versions)
+2. **Workspace** → `bun install` fetches latest from Gitea, `bun install` is safe to run anytime
+3. **Build** → produces single-file ESM bundle with `@uncaged/*` as externals
+4. **Register & Run** → `uncaged-workflow workflow add <name> <bundle>` then `uncaged-workflow run <name>`

+# RFC: Merkle Call Stack — Cross-Thread DAG Linking
+
+**Author:** 小橘 🍊（NEKO Team）
+**Date:** 2026-05-11
+**Status:** Draft
+
+## Problem
+
+当 `workflowAsAgent` 在父 workflow 中 spawn 子 workflow 时，父子 thread 之间没有任何 Merkle 链接：
+
+1. **子 thread 不知道自己从哪来** — start node 只有 prompt hash，无法追溯父 thread 的上下文（preparer 分析出的 repoPath、conventions 等）
+2. **父 thread 不知道子 thread 在哪** — developer role 的 state node 里只有 agent 返回的文本，child thread root hash 埋在字符串里，不是结构化 ref
+3. **上下文传递靠序列化到 prompt** — 父 workflow 前置 role 的产出只能通过拼字符串传给子 workflow，丢失了 Merkle DAG 的可遍历性
+
+## Proposal
+
+在 CAS 节点中建立父子 thread 之间的 **双向 Merkle 链接**，形成调用栈结构。
+
+### 新增字段
+
+#### StartNodePayload（子 → 父）
+
+```typescript
+type StartNodePayload = {
+  name: string;
+  hash: string;
+  depth: number;
+  parentState: string | null;   // NEW: 父 thread 调用时的 head state hash
+};
+```
+
+`parentState` 指向子 workflow 被 spawn 时，父 thread 的最后一个 state node hash。这是"调用发生时的调用栈帧"。
+
+#### StateNodePayload（父 → 子）
+
+```typescript
+type StateNodePayload = {
+  role: string;
+  meta: Record<string, unknown>;
+  start: string;
+  content: string;
+  ancestors: string[];
+  compact: string | null;
+  timestamp: number;
+  childThread: string | null;   // NEW: 子 thread 最终 state hash（执行结果）
+};
+```
+
+`childThread` 指向子 thread 完成后的**最终 state hash**（不是 start）——语义上是"函数返回值"，从这里沿 ancestors 可回溯子 thread 的完整执行历史。
+
+### refs 同步
+
+新增的 hash 也必须放进 `refs[]`：
+
+- `StartNode.refs`: `[promptHash, parentState]`（parentState 非 null 时）
+- `StateNode.refs`: `[...existingRefs, childThread]`（childThread 非 null 时）
+
+原因：GC 的 `findReachableHashes` 只走 `refs`，不解析 payload 字段。字段提供语义，refs 保证可达性。
+
+### 具体 DAG 结构
+
+以 `solve-issue`（fix #191）为例，developer role 委托给 `develop` 子 workflow：
+
+```

+```
+
+### 遍历路径
+
+**子 thread agent 获取父上下文（上行）：**
+```
+当前 step → start(CHILD_START)
+  → refs[1] = STATE_P1（父 preparer 的 state）
+    → payload.meta.repoPath = "/home/.../workflow"
+    → refs → PREP_CONTENT（完整 preparer 输出）
+    → payload.start = START001（父的 start node）
+      → refs[0] = ABCD1234（原始 prompt）
+```
+
+**从父 thread 追踪子 thread 执行（下行）：**
+```
+STATE_D1（父 developer state）
+  → payload.childThread = CSTATE_END
+    → 子 thread 最终 state
+    → 沿 ancestors 回溯：committer → tester → reviewer → coder → planner
+    → payload.start = CHILD_START（子 thread 入口）
+```
+
+**完整调用栈还原：**
+```
+任意节点 → 沿 start 找到所属 thread 的 StartNode
+  → parentState 非 null？沿 parentState 进入父 thread
+  → 递归直到 parentState = null（顶层 workflow）
+```
+
+## Implementation Plan
+
+### Phase 1: Protocol + CAS 层
+
+1. `workflow-protocol/src/cas-types.ts` — `StartNodePayload` 加 `parentState: string | null`，`StateNodePayload` 加 `childThread: string | null`
+2. `workflow-cas/src/nodes.ts` — `putStartNode` 接受可选 `parentStateHash`，放入 refs；`putStateNode` 接受可选 `childThreadHash`，放入 refs
+3. `workflow-cas/src/nodes.ts` — 解析逻辑兼容新字段（缺失时视为 null）
+
+### Phase 2: Engine 层
+
+4. `workflow-execute/src/engine/engine.ts` — `executeThread` 接受 `parentStateHash: string | null`，传给 `putStartNode`
+5. `workflow-execute/src/workflow-as-agent.ts` — spawn 子 thread 时传入父 thread 当前 head state hash 作为 `parentStateHash`；子 thread 完成后返回最终 state hash
+6. Engine 写 developer role 的 state node 时，把子 thread 最终 hash 写入 `childThread` 字段
+
+### Phase 3: Agent 可观测性
+
+7. Agent prompt 构建（`buildAgentPrompt`）— 当 start node 有 `parentState` 时，提示 agent 可通过 `cas get` 遍历父上下文
+8. CLI `thread show` — 显示 parentState / childThread 链接关系
+
+### Phase 4: 验证
+
+9. 已有测试适配新字段（向后兼容，旧节点 parentState/childThread 为 null）
+10. 新增集成测试：workflowAsAgent 场景下验证双向链接正确写入
+
+## Design Decisions
+
+### 为什么 childThread 指向 end 而不是 start？
+
+- 语义是"函数返回值"——父 role 执行完才产出 state，此时子 thread 已跑完
+- 从 end 沿 ancestors 可回溯到 start；反过来 start 写入时子 thread 还没跑完，无法知道 end
+
+### 为什么 parentState 指向 state 而不是 start？
+
+- 指向父 thread 调用点的**前一个 state**（即调用发生时的 head）
+- 这是子 workflow 能看到的父上下文的"切面"——所有已完成的前置 role 都可达
+- 如果是第一个 role 就 spawn 子 workflow（没有前置 state），parentState 指向父的 start node
+
+### 为什么同时放字段和 refs？
+
+- `refs[]` 服务于 GC（`findReachableHashes` 只遍历 refs）和通用 DAG 遍历
+- `payload.parentState` / `payload.childThread` 服务于语义读取（明确知道哪个 ref 是什么）
+- 不改 GC 逻辑，只加字段，GC 自然正确
+
+### 向后兼容
+
+- 新字段默认 `null`，旧节点解析时缺失字段视为 `null`
+- 不影响已有 thread 的遍历和 GC
+- `depth` 可通过沿 parentState 链上溯来交叉验证（数据自证）
+
+## Open Questions
+
+1. **多子 thread** — 如果一个 role 需要 spawn 多个子 workflow（目前不存在这个场景），`childThread` 应该改成 `childThreads: string[]` 还是保持单个？
+2. **Agent prompt 注入深度** — 子 workflow 的 agent 应该自动遍历多少层父上下文？全部还是限制深度？
+3. **CLI 展示** — `thread show` 要不要递归展示整个调用栈，还是只显示直接链接？

+# Dashboard Workflow Graph Visualization
+
+**Issue**: #198
+**Status**: In Progress
+**Author**: xingyue
+
+## Overview
+
+在 Dashboard 的 ThreadDetail 页面中嵌入一个交互式流程图，将 workflow 的 `ModeratorTable` 可视化为有向图。用户可以一眼看到角色流转结构和当前执行进度。
+
+## 数据层（✅ 已完成 — PR #201）
+
+### WorkflowGraph 类型
+
+`WorkflowDefinition.moderator`（函数）已替换为 `WorkflowDefinition.table`（声明式 `ModeratorTable`），`buildDescriptor` 自动从 table 提取 graph：
+
+```ts
+type WorkflowGraphEdge = {
+  from: string;              // source role 或 "__start__"
+  to: string;                // target role 或 "__end__"
+  condition: string;         // condition.name 或 "FALLBACK"
+  conditionDescription: string | null;
+};
+
+type WorkflowGraph = {
+  edges: readonly WorkflowGraphEdge[];
+};
+
+type WorkflowDescriptor = {
+  description: string;
+  roles: Record<string, WorkflowRoleDescriptor>;
+  graph: WorkflowGraph;      // 必填，新 bundle 自动生成
+};
+```
+
+### 数据流
+
+```
+ModeratorTable (WorkflowDefinition.table)
+  → buildDescriptor() 自动提取 graph
+    → descriptor.yaml 持久化（hash.yaml）
+      → CLI serve /workflows/:name API 返回 descriptor
+        → Dashboard 前端拿到 graph
+```
+
+### 剩余数据层工作
+
+**serve API 需要返回 descriptor**：当前 `GET /workflows/:name` 只返回 registry entry（hash + timestamp），不含 descriptor。需要从 `bundles/{hash}.yaml` 读取 descriptor 并返回给前端。
+
+方案：在 `routes-workflow.ts` 的 `GET /workflows/:name` 响应中附带 `descriptor` 字段。或者：thread-detail 发现 workflow name 后，请求 `GET /workflows/:name/descriptor` 拿到 graph。
+
+## 前端渲染
+
+### 库选型：React Flow + dagre
+
+| 库 | 优势 | 劣势 |
+|---|---|---|
+| **React Flow** ✅ | React 原生、自定义节点/边、dagre 自动布局、~50KB gzip | 需要学 API |
+| Mermaid | 声明式简单 | 无交互、无法高亮当前步骤 |
+| D3 | 完全控制 | 太底层，手撸成本高 |
+| Cytoscape | 图论强 | React 集成差 |
+
+**依赖新增**：
+
+```json
+{
+  "@xyflow/react": "^12",
+  "@dagrejs/dagre": "^1"
+}
+```
+
+### 图结构映射
+
+```
+WorkflowGraph.edges → React Flow nodes + edges
+
+节点（自动从 edges 推导）:
+  - __start__  → 圆形小节点（入口）
+  - role       → 圆角矩形，显示 role name + description
+  - __end__    → 圆形小节点（终止）
+
+边:
+  - FALLBACK   → 虚线（dashed），无 label
+  - condition  → 实线，label = condition
+                  hover tooltip = conditionDescription
+```
+
+### 布局
+
+使用 dagre 自动计算 TB（top-to-bottom）方向布局：
+
+```ts
+import Dagre from "@dagrejs/dagre";
+
+function layoutGraph(nodes, edges) {
+  const g = new Dagre.graphlib.Graph().setDefaultEdgeLabel(() => ({}));
+  g.setGraph({ rankdir: "TB", nodesep: 60, ranksep: 80 });
+
+  for (const node of nodes) {
+    g.setNode(node.id, { width: 180, height: 60 });
+  }
+  for (const edge of edges) {
+    g.setEdge(edge.source, edge.target);
+  }
+
+  Dagre.layout(g);
+
+  return nodes.map((node) => {
+    const pos = g.node(node.id);
+    return { ...node, position: { x: pos.x - 90, y: pos.y - 30 } };
+  });
+}
+```
+
+### 运行时高亮
+
+ThreadDetail 已有 `records: ThreadRecord[]`，其中 `RoleRecord.role` 就是当前/历史执行的 role。
+
+高亮逻辑：
+
+```ts
+function getNodeStates(records: ThreadRecord[]): Map<string, "completed" | "active"> {
+  const states = new Map<string, "completed" | "active">();
+  const roleRecords = records.filter((r) => r.type === "role");
+
+  for (let i = 0; i < roleRecords.length; i++) {
+    const role = roleRecords[i].role;
+    states.set(role, i === roleRecords.length - 1 ? "active" : "completed");
+  }
+
+  // 如果有 workflow-result，最后一个 role 也是 completed
+  if (records.some((r) => r.type === "workflow-result")) {
+    for (const [k] of states) {
+      states.set(k, "completed");
+    }
+    states.set("__end__", "completed");
+  }
+
+  states.set("__start__", "completed");
+  return states;
+}
+```
+
+节点样式：
+
+| 状态 | 样式 |
+|------|------|
+| default | `border: var(--color-border)`, 暗色背景 |
+| completed | `border: var(--color-success)`, 绿色边框 + ✓ 图标 |
+| active | `border: var(--color-accent)`, 蓝色边框 + 脉冲动画 |
+
+边高亮：当 source 和 target 都至少 completed 时，边变绿。

+### 集成到 ThreadDetail
+
+在 ThreadDetail 中，records 列表上方插入可折叠的图面板：
+
+```tsx
+// thread-detail.tsx
+{graph && (
+  <div className="mb-4 border rounded-lg overflow-hidden" style={{ height: 300 }}>
+    <WorkflowGraph graph={graph} nodeStates={getNodeStates(records)} />
+  </div>
+)}
+```
+
+图高度固定 300px，React Flow 支持 pan + zoom，不影响下方 records 滚动。
+
+## 实施计划
+
+### ~~Phase 0: 数据层~~ ✅ Done (PR #201)
+
+- [x] `WorkflowDefinition.moderator` → `table` (ModeratorTable)
+- [x] `WorkflowDescriptor` 新增 `graph: WorkflowGraph`
+- [x] `buildDescriptor` 自动提取 graph
+- [x] `validateWorkflowDescriptor` 校验 graph
+
+### Phase 1: API + 静态图渲染
+
+1. serve API：`GET /workflows/:name` 返回 descriptor（含 graph），或新增 `GET /workflows/:name/descriptor`
+2. Dashboard `api.ts` 新增 `getWorkflowDescriptor(agent, name)` 函数
+3. 安装 `@xyflow/react` + `@dagrejs/dagre`
+4. 实现 `workflow-graph/` 组件集
+5. ThreadDetail 中集成：从 thread-start record 拿 workflow name → 请求 descriptor → 渲染图
+
+**产出**：打开 ThreadDetail 看到 workflow 流程图，无高亮。
+
+### Phase 2: 运行时高亮
+
+1. ThreadDetail 根据 records 计算 nodeStates
+2. 节点/边样式响应状态变化
+3. SSE live 模式下实时更新高亮
+
+**产出**：正在运行的 thread 能看到当前执行到哪个 role。
+
+### Phase 3: 交互增强
+
+1. 点击节点滚动到对应 role 的 RecordCard
+2. 边 hover 显示 conditionDescription tooltip
+3. 节点 hover 显示 role description + schema summary
+
+**产出**：图和记录列表联动。
+
+## 注意事项
+
+- **自循环边**：如 `coder → coder (FALLBACK)`，React Flow 支持自循环，dagre 需要特殊处理（self-edge 用 loop 路径）
+- **大图性能**：dagre 在 <50 节点时性能无忧，workflow 通常 <10 个 role
+- **暗色主题**：Dashboard 已使用 CSS variables，节点/边样式复用现有色板
+- **不提交 pnpm-lock.yaml**

+# workflow-agent-react — ReAct Agent Package
+
+**Status**: RFC v3
+**Author**: 小橘 🍊
+
+## Problem
+
+现有的 agent 包都依赖外部 CLI 进程：
+
+| Package | 机制 | 能力 |
+|---------|------|------|
+| `workflow-agent-hermes` | spawn `hermes chat` | 完整工具链（文件、终端、浏览器…） |
+| `workflow-agent-cursor` | spawn `cursor-agent` | IDE 级别代码编辑 |
+| `workflow-agent-llm` | 单轮 chat completion | 纯文本，无工具 |
+
+缺少一个 **内置 ReAct agent**：用 LLM + tool calling 循环执行任务，不依赖外部 CLI，工具集由调用方注入。
+
+## 核心设计变更：AdapterFn 替代 AgentFn
+
+### 现状的问题
+
+当前 `AgentFn` 返回 `string`，engine 再用额外一轮 LLM 调用 extract meta：
+
+```
+Agent(ctx) → string → Extract(string, schema) → meta   // 浪费一轮 LLM
+```
+
+### 新抽象：AdapterFn
+
+```typescript
+type RoleFn<T> = (ctx: ThreadContext) => Promise<T>;
+
+type AdapterFn = <T>(prompt: string, schema: z.ZodType<T>) => RoleFn<T>;
+```
+
+- **`prompt`** — role 的 system prompt，描述角色职责和输出要求
+- **`schema`** — role 的 meta schema，定义输出格式
+- **`ThreadContext`** — threadId, depth, bundleHash, start, steps
+
+prompt 和 schema 是一对：prompt 说"你要输出什么"，schema 定义"输出的格式"。它们属于 role definition，由 `createWorkflow` 在每个 role 执行时传给 adapter。
+
+### AgentContext 不再需要
+
+`AgentContext` 在 `ThreadContext` 上扩展了 `currentRole: { name, systemPrompt }`。prompt 现在直接传给 adapter，`AgentContext` 可以删除。
+
+### createWorkflow 签名变更
+
+```typescript
+// Before
+type AgentBinding = {
+  agent: AgentFn;
+  overrides: Partial<Record<string, AgentFn>> | null;
+};
+
+// After
+type AdapterBinding = {
+  adapter: AdapterFn;
+  overrides: Partial<Record<string, AdapterFn>> | null;
+};
+```
+
+engine 对每个 role 的执行逻辑：
+
+```typescript
+// Before
+const result = await agent({ ...threadCtx, currentRole: { name, systemPrompt } });
+const meta = await extract(result, role.metaSchema, provider);  // 额外一轮 LLM
+
+// After
+const roleFn = adapter(role.systemPrompt, role.metaSchema);
+const meta = await roleFn(threadCtx);  // 直接拿到类型安全的 T
+```
+
+## `createReactAdapter` — 复用 workflow-reactor
+
+AdapterFn 的终止条件是"拿到符合 schema 的 T"——和 `workflow-reactor` 的 `ThreadReactorFn` 完全一致。因此 react adapter 是对 reactor 的**薄包装**，不需要自己实现 ReAct 循环。
+
+```typescript
+import { createLlmFn, createThreadReactor } from "@uncaged/workflow-reactor";
+import type { ThreadContext, LlmProvider } from "@uncaged/workflow-protocol";
+import type { ToolDefinition } from "@uncaged/workflow-reactor";
+
+type ReactToolHandler = (name: string, args: string) => Promise<string>;
+
+type ReactAdapterConfig = {
+  provider: LlmProvider;
+  tools: readonly ToolDefinition[];
+  toolHandler: ReactToolHandler;
+  maxRounds: number;
+};
+
+function createReactAdapter(config: ReactAdapterConfig): AdapterFn {
+  return <T>(prompt: string, schema: z.ZodType<T>) => {
+    const reactor = createThreadReactor<ThreadContext>({
+      llm: createLlmFn(config.provider),
+      staticTools: config.tools,
+      structuredToolFromSchema: (s) => buildStructuredTool(s),
+      systemPromptForStructuredTool: () => prompt,
+      toolHandler: (call, ctx) =>
+        config.toolHandler(call.function.name, call.function.arguments),
+      maxRounds: config.maxRounds,
+    });
+
+    return async (ctx: ThreadContext): Promise<T> => {
+      const input = buildThreadInput(ctx);
+      const result = await reactor({ thread: ctx, input, schema });
+      if (!result.ok) throw new Error(result.error);
+      return result.value;
+    };
+  };
+}
+```
+
+整个包就是：**一个工厂函数 + 类型定义 + thread 输入构造**。
+
+## `agentToAdapter` — 向后兼容
+
+把现有 `AgentFn`（hermes/cursor）包装成 `AdapterFn`：
+
+```typescript
+function agentToAdapter(agent: AgentFn, extractProvider: LlmProvider): AdapterFn {
+  return <T>(prompt: string, schema: z.ZodType<T>): RoleFn<T> => {
+    return async (ctx: ThreadContext): Promise<T> => {
+      const agentCtx = { ...ctx, currentRole: { name: "agent", systemPrompt: prompt } };
+      const result = await agent(agentCtx);
+      const output = typeof result === "string" ? result : result.output;
+      return extract(output, schema, extractProvider);
+    };
+  };
+}
+```
+
+hermes/cursor agent 内部不改，bundle-entry 层多包一层即可。
+
+## 包结构
+
+```
+packages/workflow-agent-react/
+  src/
+    types.ts                 # ReactAdapterConfig, ReactToolHandler
+    create-react-adapter.ts  # AdapterFn 工厂（包装 reactor）
+    thread-input.ts          # ThreadContext → user message string
+    index.ts
+  __tests__/
+    create-react-adapter.test.ts
+  package.json
+```
+
+依赖：
+- `@uncaged/workflow-protocol` — `ThreadContext`, `LlmProvider`
+- `@uncaged/workflow-reactor` — `createLlmFn`, `createThreadReactor`, types
+
+## 影响范围
+
+### Breaking Changes
+
+| 改动 | 影响 |
+|------|------|
+| `AgentBinding` → `AdapterBinding` | `createWorkflow` 调用方（所有 bundle-entry） |
+| `AgentContext` 删除 | `buildAgentPrompt`（util-agent）改为接收 `ThreadContext` |
+| extract 从 engine 下沉到 adapter | `workflow-execute` 简化 |
+
+### 需修改的包
+
+1. `workflow-protocol` — 删除 `AgentContext`/`AgentFn`/`AgentFnResult`/`AgentBinding`，新增 `AdapterFn`/`RoleFn`/`AdapterBinding`
+2. `workflow-runtime` — 更新 re-export
+3. `workflow-execute` — engine 调用 `adapter(prompt, schema)` 替代 `agent(ctx) + extract`
+4. `workflow-util-agent` — `buildAgentPrompt` → `buildThreadInput`，接收 `ThreadContext`
+5. 所有 bundle-entry — `agent:` → `adapter:`
+
+### 不受影响
+
+- `workflow-cas` / `workflow-register` / `workflow-reactor` / `workflow-dashboard`
+- `workflow-agent-hermes` / `workflow-agent-cursor`（内部不改，外部用 `agentToAdapter` 包装）
+
+## Phases
+
+1. **Phase 1**: protocol 类型 + `createWorkflow` 签名变更 + `agentToAdapter`
+2. **Phase 2**: `workflow-agent-react` 包（包装 reactor）
+3. **Phase 3**: 工具集实现（read/write/patch/shell） + smoke test 闭环
+
+## 工具集（后续讨论）
+
+| 工具 | 说明 | 优先级 |
+|------|------|--------|
+| `read_file` | 读文件 | P0 |
+| `write_file` | 写文件 | P0 |
+| `patch_file` | find-and-replace 编辑 | P0 |
+| `shell_exec` | 执行 shell 命令 | P0 |
+| `search_files` | grep / find | P1 |
+| `list_files` | ls | P1 |

 5. **实例化**：在 workflow 包中使用 \`createWorkflow(def, binding)\`（或项目约定的封装）绑定 **AgentFn**；**ExtractFn** 由引擎从 **workflow.yaml** 注入 \`WorkflowRuntime\`。
 6. **构建**：打包为单个 **.esm.js** bundle，使用 **uncaged-workflow add** 注册。
