feat: ACP 协议版本 remote control (#293)

* fix: 添加 usage 字段缺失时的防御性防护

第三方 API（如智谱 GLM）在某些流式响应中不返回 usage 字段，
导致 usage.input_tokens 访问 undefined 崩溃并连锁影响后续所有请求。

- claude.ts: content_block_stop 创建消息时 fallback 到 EMPTY_USAGE
- LocalAgentTask.tsx: usage 为 undefined 时提前返回
- tokens.ts: getTokenCountFromUsage 加 null guard 和 ?? 0
- cost-tracker.ts: input_tokens/output_tokens 加 ?? 0

* feat: ACP Plan 展示 — 支持 session/update plan 类型的可视化

补全 PlanUpdate 类型定义（PlanEntry/Priority/Status），新建 PlanView 组件
渲染进度条、状态图标和优先级标签，在 ChatInterface 中处理 plan 更新逻辑。

* feat: 穷鬼模式下跳过 verification agent 以节省 token

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* test: 补充 RCS 后端 + 前端测试覆盖 (+116 tests)

后端新增 3 个测试文件 (70 tests):
- automationState: normalize/snapshot/equals 纯函数
- client-payload: toClientPayload 协议转换
- transport-normalize: normalizePayload + extractContent

前端新增 2 个测试文件 (46 tests):
- utils: formatTime/statusClass/truncate/extractEventText 等
- api-client: getUuid/setUuid/api GET/POST 错误处理

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* feat: RCS ACP 页面添加权限模式选择器 + 权限响应修复

- 新增权限模式选择器 UI（6种模式：默认/自动接受编辑/跳过权限/规划/不询问/自动判断）
- 权限模式通过 ACP _meta 从 web → acp-link → agent 全链路传递
- 修复 PermissionPanel 点击"允许"发送 cancelled 而非 selected 的 bug
- 权限模式和模型选择持久化到 localStorage
- acp-link 直接连接路径同步支持 permissionMode 透传

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* feat: RCS Web UI 重构 + QR 修复 + ACP 扫描自动跳转

- RCS Web UI 组件全面重构: Dialog 迁移 Radix UI, lazy loading,
  主题系统改进, 组件样式优化
- IdentityPanel QR 码显示修复: requestAnimationFrame 延迟绘制
  解决 Radix Dialog Portal 挂载时序问题
- ACP QR 扫描自动跳转: IdentityPanel 扫描 ACP 格式 { url, token }
  后存储 sessionStorage 并跳转 /code/?acp=1
- 新增 ACPDirectView 组件: ACP 直连视图, 用 ACPClient 连接并
  渲染 ACPMain 聊天界面

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* feat: ACP 权限管道改进 — 模式同步 + bypass 检测 + 统一权限流水线

- agent.ts: applySessionMode 同步 appState.toolPermissionContext.mode
- agent.ts: bypassPermissions 可用性检测 (非 root 或 sandbox 环境)
- permissions.ts: createAcpCanUseTool 接入 hasPermissionsToUseTool
  统一权限流水线, 替代原来分散的处理逻辑
- permissions.ts: 支持 onModeChange 回调, 模式变更时实时同步

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: acp-link 支持 permissionMode 默认值传递给 agent

客户端 (Zed/VS Code 等) 的 new_session 不一定携带 permissionMode,
导致 agent 收到 _meta: undefined, permission 回退到 default。

修复: handleNewSession 使用 fallback 链:
  客户端传值 > config.permissionMode > ACP_PERMISSION_MODE 环境变量

使用: ACP_PERMISSION_MODE=auto acp-link claude

+# Impeccable Design Context
+
+## Users
+
+**Primary**: Technical teams and enterprises using AI-assisted coding in production workflows.
+- DevOps engineers managing remote agents via RCS dashboard
+- Development teams collaborating through shared sessions
+- Individual developers using terminal CLI daily
+
+**Context**: Used during focused work sessions — debugging, code review, agent orchestration. Users are in "get things done" mode, not browsing. They value efficiency but also appreciate warmth and personality.
+
+**Job to be done**: Make advanced AI coding tools accessible and controllable, especially features that normally require enterprise accounts or Anthropic OAuth.
+
+## Brand Personality
+
+**3 words**: Warm, Considered, Human
+
+**Voice**: Like a knowledgeable colleague who's genuinely enthusiastic about the craft — not a corporate product manager. Community-first, open, slightly playful. Chinese developer community culture (贴吧/discord 温暖氛围).
+
+**Emotional goals**: Confidence (this tool is solid), Warmth (this community is welcoming), Delight (small moments of personality make the difference).
+
+**References**:
+- **Anthropic's own design language** — their clean, considered aesthetic with warm undertones. The terra cotta/burnt orange as a human accent. Lots of breathing room. Typography-forward.
+- **NOT**: Generic AI product (no ChatGPT blue, no gradient text, no "AI slop"). NOT corporate SaaS (no Salesforce-blue dashboards, no enterprise sterility).
+
+**Anti-references**: Corporate enterprise dashboards, generic AI product pages, anything that looks like it was "designed by committee."
+
+## Aesthetic Direction
+
+**Theme**: Light + Dark dual mode (user/system preference switch)
+
+**Tone**: Anthropomorphic warmth meets terminal precision. The brand orange (Claude's terra cotta) is the thread that ties everything together — it's the human element in a technical world.
+
+**Typography**: Clean, considered, with good hierarchy. Terminal-native for CLI; modern web fonts for Web UI (RCS dashboard, docs). Favor readability and personality.
+
+**Color**:
+- Primary: Claude orange family (`#D77757` / terra cotta)
+- Accent: Warm neutrals tinted toward orange
+- Semantic: Success/Error/Warning following Anthropic's established palette
+- Dark mode: Warm dark surfaces (not cold blue-black)
+
+**Differentiation**: The CCB brand sits at the intersection of "serious tool" and "community project." It should feel like Anthropic's design principles applied to an open-source context — less corporate polish, more human craft. The mascot "Clawd" and the playful "踩踩背" naming hint at personality that the design should honor.
+
+**Scope**: All Web UI — RCS control panel, documentation site, landing pages.
+
+## Design Principles
+
+1. **Considered over clever** — Every design choice should feel intentional, not trendy. If it doesn't serve the user, it doesn't ship.
+2. **Warmth through subtlety** — Orange tints on neutrals, breathing room in layouts, personality in copy. Not giant emoji or aggressive color.
+3. **Density with clarity** — Technical users need information density, but not chaos. Every pixel earns its place.
+4. **Community voice** — The design should feel like it was made by people who use it, not by a distant design team. Slightly rough edges are fine if they're honest.
+5. **Anthropic's shadow** — When in doubt, follow Anthropic's design instincts — the clean layouts, the generous spacing, the warm color temperature. Then add the community touch.
+
+## Existing Design Assets
+
+### Brand Colors (from theme system)
+- Claude Orange: `rgb(215,119,87)` / `#D77757`
+- Claude Blue: `rgb(87,105,247)` / `#5769F7`
+- Permission Blue: `rgb(87,105,247)`
+- Auto Accept Violet: `rgb(135,0,255)`
+- Plan Mode Teal: `rgb(0,102,102)`
+- Success: `rgb(78,186,101)`
+- Error: `rgb(255,107,128)`
+- Warning: `rgb(255,193,7)`
+
+### Logo
+- CCB text + orange play button icon
+- Dark/Light SVG variants in `docs/logo/`
+- Favicon: Orange circle `#D97706` with white play triangle
+
+### Mascot
+- "Clawd" — terminal-art character with multiple poses
+- Theme-aware coloring
+
+### Theme System
+- 7 variants: dark, light, dark-ansi, light-ansi, dark-daltonized, light-daltonized, auto
+- 89+ semantic color tokens

+2. **Warmth through subtlety** — 通过橙色色调的中性色、留白布局、有温度的文案来传达温暖
+3. **Density with clarity** — 技术用户需要信息密度，但不能混乱
+4. **Community voice** — 设计应感觉是由使用者创造的，而非遥远的设计团队
+5. **Anthropic's shadow** — 遵循 Anthropic 的设计直觉：干净的布局、充足的间距、温暖的色温
+
+### 品牌色
+
+- 主色：Claude Orange `#D77757`（terra cotta）
+- 辅色：Claude Blue `#5769F7`
+- 暗色模式使用温暖的深色表面（非冷蓝黑色）
+
+### 目标用户
+
+技术团队/企业，在专业工作流中使用 AI 辅助编程。友好的开源社区氛围，非企业 SaaS 风格。
+
+### 视觉参考
+
+Anthropic 公司的设计风格 — 干净、考究、温暖的底色。大量留白，以排版为核心。避免 AI 产品常见的设计套路（渐变文字、玻璃态、霓虹色）。

+# acp-link — ACP 代理服务器
+
+> 源码目录：`packages/acp-link/`
+> PR: #292
+> 新增时间：2026-04-18
+
+## 一、功能概述
+
+`acp-link` 是一个 ACP (Agent Client Protocol) 代理服务器，将 WebSocket 客户端桥接到 ACP agent 的 stdio 接口。它让 ACP agent（如 Claude Code）可以通过 WebSocket 远程访问，而不仅限于本地 stdio。
+
+### 核心特性
+
+- **WebSocket → stdio 桥接**：将浏览器/远程客户端的 WebSocket 连接转换为 ACP agent 的 stdin/stdout NDJSON 流
+- **会话管理**：创建、加载、恢复、列出、关闭会话
+- **权限审批流程**：客户端可远程审批 agent 的工具权限请求
+- **RCS 集成**：可与 Remote Control Server (RCS) 连接，将 ACP agent 注册到 RCS 并通过 Web UI 交互
+- **HTTPS 支持**：内置自签名证书生成，支持安全连接
+- **Token 认证**：自动生成或通过环境变量配置认证 token
+
+## 二、架构
+
+### 独立模式
+
+```
+┌──────────────────┐    WebSocket     ┌──────────────────┐    stdio/NDJSON    ┌──────────────┐

+```
+
+## 三、安装与使用
+
+### 基本用法
+
+```bash
+# 直接运行（在 monorepo 中）
+# 注意：claude 本身不支持 ACP，需要用 ccb-bun --acp 启动 ACP agent
+bun packages/acp-link/src/cli/bin.ts ccb-bun -- --acp
+
+# 指定端口和主机
+acp-link --port 9000 --host 0.0.0.0 ccb-bun -- --acp
+
+# 启用 HTTPS（自签名证书）
+acp-link --https ccb-bun -- --acp
+
+# 调试模式
+acp-link --debug ccb-bun -- --acp
+```
+
+### CLI 参考
+
+```
+USAGE
+  acp-link [--port value] [--host value] [--debug] [--no-auth] [--https] <command>...
+  acp-link --help
+  acp-link --version
+
+FLAGS
+       [--port]     Port to listen on                  [default = 9315]
+       [--host]     Host to bind to                    [default = localhost]
+       [--debug]    Enable debug logging to file
+       [--no-auth]  Disable authentication (dangerous)
+       [--https]    Enable HTTPS with self-signed cert
+    -h  --help      Print help information and exit
+    -v  --version   Print version information and exit
+
+ARGUMENTS
+  command...  Agent command followed by its arguments (e.g. "ccb-bun -- --acp")
+```
+
+## 四、认证
+
+默认启动时自动生成随机 token。客户端连接时需通过 query 参数传递：
+
+```
+ws://localhost:9315/ws?token=<your-token>
+```
+
+配置固定 token：
+
+```bash
+ACP_AUTH_TOKEN=my-fixed-token acp-link ccb-bun -- --acp
+```
+
+禁用认证（不推荐，仅用于开发）：
+
+```bash
+acp-link --no-auth ccb-bun -- --acp
+```
+
+## 五、RCS 集成
+
+acp-link 支持将 ACP agent 注册到 Remote Control Server，通过 Web UI 远程操控。
+
+### 连接方式
+
+```bash
+# 通过环境变量配置 RCS 连接
+ACP_RCS_URL=http://localhost:3000 \
+ACP_RCS_TOKEN=sk-rcs-your-key \
+ACP_RCS_NAME=my-agent \
+acp-link ccb-bun -- --acp
+```
+
+### 注册流程（两步）
+
+1. **REST 注册**：通过 `POST /v1/environments/bridge` 向 RCS 注册环境
+2. **WS identify**：建立 WebSocket 连接后发送 `identify` 消息（携带 agentId），替代完整 `register`
+
+```
+acp-link                          RCS
+   │                                │
+   │── POST /v1/environments/bridge ──►│  (REST 注册)
+   │◄── { agentId, sessionId } ───────│
+   │                                │
+   │── WS connect ─────────────────►│  (WebSocket)
+   │── identify { agentId } ────────►│  (WS 标识)
+   │◄── registered ─────────────────│
+   │                                │
+   │── ACP events ─────────────────►│  (双向消息转发)
+   │◄── user prompts/permissions ───│
+```
+
+## 六、权限模式
+
+### permissionMode 传递链
+
+权限模式通过整条链路传递：Web UI → RCS → acp-link → ACP agent。
+
+支持的权限模式：
+- `default` — 每次请求权限确认
+- `auto` — 自动判断
+- `acceptEdits` — 自动接受编辑
+- `plan` — 规划模式
+- `dontAsk` — 不询问
+- `bypassPermissions` — 绕过权限（需 sandbox 环境）
+
+### fallback 链
+
+当客户端未显式传递 permissionMode 时，使用以下 fallback 链：
+
+```
+客户端传值 > config.permissionMode > ACP_PERMISSION_MODE 环境变量
+```
+
+示例：
+
+```bash
+ACP_PERMISSION_MODE=auto acp-link ccb-bun -- --acp
+```
+
+## 七、权限管道（2026-04-18 改进）
+
+### 模式同步
+
+`applySessionMode` 在 agent 切换权限模式时同步 `appState.toolPermissionContext.mode`，确保内部权限上下文与 ACP 客户端状态一致。
+
+### 统一权限流水线
+
+`createAcpCanUseTool` 接入 `hasPermissionsToUseTool` 统一权限流水线，替代原来分散的处理逻辑。支持 `onModeChange` 回调，模式变更时实时同步。
+
+### bypass 检测
+
+`bypassPermissions` 模式增加可用性检测 — 仅在非 root 或 sandbox 环境中允许启用，防止权限绕过的安全风险。
+
+## 八、环境变量
+
+| 变量 | 说明 |
+|------|------|
+| `ACP_AUTH_TOKEN` | 固定认证 token（默认自动生成） |
+| `ACP_PERMISSION_MODE` | 默认权限模式 fallback |
+| `ACP_RCS_URL` | RCS 服务器地址（启用 RCS 集成） |
+| `ACP_RCS_TOKEN` | RCS API token |
+| `ACP_RCS_NAME` | Agent 名称（在 RCS 中显示） |
+| `ACP_RCS_CHANNEL_GROUP` | Channel group ID |
+| `ACP_MAX_SESSIONS` | 最大会话数 |

+### 文件职责
+
+| 文件 | 职责 |
+|------|------|
+| `entry.ts` | 入口，创建 stdio → NDJSON stream，启动 `AgentSideConnection` |
+| `agent.ts` | 实现 ACP `Agent` 接口：会话 CRUD、prompt、cancel、模式/模型切换 |
+| `bridge.ts` | `SDKMessage` → ACP `SessionUpdate` 转换：文本/思考/工具/用量/编辑 diff |
+| `permissions.ts` | ACP `requestPermission()` → CCB `CanUseToolFn` 桥接 |
+| `utils.ts` | Pushable、流转换、权限模式解析、session fingerprint、路径显示 |
+
+## 三、配置 Zed 编辑器
+
+### 3.1 Zed settings.json 配置
+
+打开 Zed 的 `settings.json`（`Cmd+,` → Open Settings），添加 `agent_servers` 配置：
+
+```json
+{
+  "agent_servers": {
+    "ccb": {
+      "type": "custom",
+      "command": "ccb",
+      "args": ["--acp"]
+    }
+  }
+}
+```
+
+### 3.3 API 认证配置
+
+CCB 的 ACP agent 在启动时会自动加载 `settings.json` 中的环境变量（`ANTHROPIC_BASE_URL`、`ANTHROPIC_AUTH_TOKEN` 等）。确保已通过 `/login` 配置好 API 供应商。
+
+也可通过环境变量传入：
+
+```json
+{
+  "agent_servers": {
+    "claude-code": {
+      "command": "ccb",
+      "args": ["--acp"],
+      "env": {
+        "ANTHROPIC_BASE_URL": "https://api.example.com/v1",
+        "ANTHROPIC_AUTH_TOKEN": "sk-xxx"
+      }
+    }
+  }
+}
+```
+
+### 3.4 在 Zed 中使用
+
+1. 配置完成后重启 Zed
+2. 打开任意项目目录
+3. 按 `Cmd+'`（macOS）或 `Ctrl+'`（Linux）打开 Agent Panel
+4. 在 Agent Panel 顶部的下拉菜单中选择 **claude-code**
+5. 开始对话
+
+### 3.5 功能说明
+
+| 功能 | 操作 |
+|------|------|
+| 对话 | 在 Agent Panel 中直接输入消息 |
+| 斜杠命令 | 输入 `/` 查看可用 skills 列表（如 `/commit`、`/review`） |
+| 工具权限 | 弹出权限请求时选择 Allow / Reject / Always Allow |
+| 模式切换 | 通过 Agent Panel 的设置菜单切换 auto/default/plan 等模式 |
+| 模型切换 | 通过 Agent Panel 的设置菜单切换 AI 模型 |
+| 会话恢复 | 关闭重开 Zed 后，之前的会话可自动恢复（含历史消息） |
+
+## 四、配置其他 ACP 客户端
+
+ACP 是开放协议，任何支持 ACP 的客户端都可以连接 CCB。通用配置模式：
+
+```
+命令: ccb --acp
+参数: ["--acp"]
+通信: stdin/stdout NDJSON
+协议版本: ACP v1
+```
+
+### 4.1 Cursor
+
+在 Cursor 的设置中配置 MCP / Agent Server，使用同样的 `ccb --acp` 命令。
+
+### 4.2 自定义客户端
+
+使用 `@agentclientprotocol/sdk` 可以快速构建 ACP 客户端：
+
+```typescript
+import { ClientSideConnection, ndJsonStream } from '@agentclientprotocol/sdk'
+
+// 创建连接（将 ccb --acp 作为子进程启动）
+const child = spawn('ccb', ['--acp'])
+const stream = ndJsonStream(
+  Writable.toWeb(child.stdin),
+  Readable.toWeb(child.stdout),
+)
+
+const client = new ClientSideConnection(stream)
+
+// 初始化
+await client.initialize({ clientCapabilities: {} })
+

+
+## 一、问题概述
+
+### 1.1 命令结构散乱
+
+当前后台进程相关的命令分布在三个不同的位置，没有统一的命名空间：
+
+| 命令 | 注册位置 | 入口 |
+|------|---------|------|
+| `claude daemon start/status/stop` | `cli.tsx` 快速路径 L203 | `daemon/main.ts` |
+| `claude ps` | `cli.tsx` 快速路径 L220 | `cli/bg.ts` |
+| `claude logs <x>` | `cli.tsx` 快速路径 L232 | `cli/bg.ts` |
+| `claude attach <x>` | `cli.tsx` 快速路径 L236 | `cli/bg.ts` |
+| `claude kill <x>` | `cli.tsx` 快速路径 L238 | `cli/bg.ts` |
+| `claude --bg` | `cli.tsx` 快速路径 L244 | `cli/bg.ts` |
+| `claude new/list/reply` | `cli.tsx` 快速路径 L250 | `cli/handlers/templateJobs.ts` |
+| `claude rollback` | `main.tsx` Commander.js L6525 | `cli/rollback.ts` |
+| `claude up` | `main.tsx` Commander.js L6511 | `cli/up.ts` |
+
+**问题**:
+- `ps/logs/attach/kill` 与 `daemon` 逻辑上都是后台进程管理，但互不关联
+- 这些命令都**只有 CLI 入口**，REPL 里输入 `/daemon` 或 `/ps` 不存在
+- `new/list/reply` 是模板任务系统的顶级命令，容易与其他命令冲突（特别是 `list`）
+
+### 1.2 Windows 不支持
+
+`--bg` 和 `attach` 硬依赖 tmux：
+- `bg.ts:handleBgFlag()` 第一步就检查 tmux，不可用直接报错退出
+- `bg.ts:attachHandler()` 用 `tmux attach-session`，无 tmux 替代方案
+- Windows (包括 VS Code 终端) 完全无法使用后台会话功能
+
+### 1.3 无 REPL 入口
+
+对比 `/mcp` 的双注册模式：
+- **CLI**: `claude mcp serve/add/remove/list` (Commander.js, `main.tsx:5760`)
+- **REPL**: `/mcp enable/disable/reconnect` (slash command, `commands/mcp/index.ts`)
+
+`daemon`/`bg`/`job` 系列只有 CLI 快速路径，REPL 中完全不可用。
+
+## 二、目标
+
+1. **层级化命令结构**: 参照 `/mcp` 模式，将后台管理收归 `/daemon`，模板任务收归 `/job`
+2. **跨平台后台会话**: Windows / macOS / Linux 都能启动、附着、终止后台会话
+3. **双注册**: CLI (`claude daemon ...`) + REPL (`/daemon ...`) 同时可用
+4. **向后兼容**: 旧命令保留但输出 deprecation 提示
+
+## 三、命令结构设计
+
+### 3.1 `/daemon` — 后台进程管理
+
+合并 daemon supervisor + bg sessions 为统一命名空间：
+
+```
+claude daemon <subcommand>     ← CLI 入口 (cli.tsx 快速路径)
+/daemon <subcommand>           ← REPL 入口 (slash command, local-jsx)
+
+子命令:
+  status                       综合状态面板 (daemon + 所有会话)
+  start [--dir <path>]         启动 daemon supervisor
+  stop                         停止 daemon
+  bg [args...]                 启动后台会话
+  attach [target]              附着到后台会话
+  logs [target]                查看会话日志
+  kill [target]                终止会话
+  (无参数)                     等同于 status
+```
+
+**CLI 快速路径路由** (`cli.tsx`):
+```typescript
+// 新: 统一入口
+if (feature('DAEMON') && args[0] === 'daemon') {
+  const sub = args[1] || 'status'
+  switch (sub) {
+    case 'start': case 'stop': case 'status':
+      await daemonMain([sub, ...args.slice(2)])
+      break
+    case 'bg':
+      await bg.handleBgStart(args.slice(2))
+      break
+    case 'attach': case 'logs': case 'kill':
+      await bg[`${sub}Handler`](args[2])
+      break
+  }
+}
+
+// 向后兼容 (deprecated)
+if (feature('BG_SESSIONS') && ['ps','logs','attach','kill'].includes(args[0])) {
+  console.warn(`[deprecated] Use: claude daemon ${args[0] === 'ps' ? 'status' : args[0]}`)
+  // ... delegate to daemon subcommand
+}
+```
+
+**REPL 斜杠命令** (`commands/daemon/index.ts`):
+```typescript
+const daemon = {
+  type: 'local-jsx',
+  name: 'daemon',
+  description: 'Manage background sessions and daemon',
+  argumentHint: '[status|start|stop|bg|attach|logs|kill]',
+  isEnabled: () => feature('DAEMON') || feature('BG_SESSIONS'),
+  load: () => import('./daemon.js'),
+} satisfies Command
+```
+
+### 3.2 `/job` — 模板任务管理
+
+```
+claude job <subcommand>        ← CLI 入口
+/job <subcommand>              ← REPL 入口
+
+子命令:
+  list                         列出模板和活跃任务
+  new <template> [args]        从模板创建任务
+  reply <id> <text>            回复任务
+  status <id>                  查看任务状态
+  (无参数)                     等同于 list
+```
+
+### 3.3 独立命令 (不变)
+
+```
+claude up                      保持顶级 (简短的 bootstrap 命令)
+claude rollback [target]       保持顶级 (低频运维命令)
+```
+
+## 四、跨平台后台引擎
+
+### 4.1 引擎抽象
+
+```typescript
+// src/cli/bg/engine.ts
+export interface BgEngine {
+  readonly name: string
+
+  /** 当前平台是否可用 */
+  available(): Promise<boolean>
+
+  /** 启动后台会话 */
+  start(opts: BgStartOptions): Promise<BgStartResult>
+
+  /** 附着到后台会话（blocking） */
+  attach(session: SessionEntry): Promise<void>
+}
+
+export interface BgStartOptions {
+  sessionName: string
+  args: string[]
+  env: Record<string, string | undefined>
+  logPath: string
+  cwd: string
+}
+
+export interface BgStartResult {
+  pid: number
+  sessionName: string
+  logPath: string
+  engineUsed: string
+}
+```
+
+### 4.2 三种引擎实现
+
+| 引擎 | 平台 | 启动方式 | attach 方式 |
+|------|------|---------|------------|
+| TmuxEngine | macOS/Linux (有 tmux) | `tmux new-session -d` | `tmux attach-session` |
+| DetachedEngine | Windows / 无 tmux 的 macOS/Linux | `spawn({ detached, stdio→logFile })` | `tail -f` 日志文件 |
+
+#### DetachedEngine 详细设计
+
+**启动 (`start`)**:
+```typescript
+// 1. 打开日志文件 fd
+const logFd = fs.openSync(logPath, 'a')
+// 2. detached spawn, stdout/stderr 重定向到日志
+const child = spawn(process.execPath, execArgs, {
+  detached: true,
+  stdio: ['ignore', logFd, logFd],
+  env,
+  cwd,
+})
+child.unref()
+fs.closeSync(logFd)
+// 3. 写 sessions/<PID>.json
+```
+
+**附着 (`attach`)**:
+```typescript
+// 跨平台 tail -f 实现
+// 1. 读取已有日志内容输出到 stdout
+// 2. fs.watch(logPath) 监听变化
+// 3. 每次变化读取新增内容
+// 4. Ctrl+C 退出 tail（不杀后台进程）
+```
+
+#### 引擎选择逻辑
+
+```typescript
+// src/cli/bg/engines/index.ts
+export async function selectEngine(): Promise<BgEngine> {
+  if (process.platform === 'win32') {
+    return new DetachedEngine()
+  }
+
+  const tmux = new TmuxEngine()
+  if (await tmux.available()) {
+    return tmux
+  }
+
+  return new DetachedEngine()
+}
+```
+
+### 4.3 SessionEntry 扩展
+
+```typescript
+interface SessionEntry {
+  // ... 现有字段
+  engine: 'tmux' | 'detached'   // 新增: 记录使用的引擎
+  tmuxSessionName?: string       // tmux 引擎才有
+  logPath?: string               // 两种引擎都有
+}
+```
+
+`attach` 时根据 `session.engine` 选择对应的 attach 策略。
+
+## 五、文件变更清单
+
+### 新增文件 (10 个)
+
+```
+src/cli/bg/engine.ts                   BgEngine 接口定义
+src/cli/bg/engines/tmux.ts             TmuxEngine (从 bg.ts 提取)
+src/cli/bg/engines/detached.ts         DetachedEngine (新实现)
+src/cli/bg/engines/index.ts            引擎选择 + re-export
+src/cli/bg/tail.ts                     跨平台日志 tail (用于 detached attach)
+src/commands/daemon/index.ts           /daemon REPL 斜杠命令注册
+src/commands/daemon/daemon.tsx         /daemon 子命令路由 + status UI
+src/commands/job/index.ts              /job REPL 斜杠命令注册
+src/commands/job/job.tsx               /job 子命令路由 + UI
+docs/features/daemon-restructure-design.md  本设计文档
+```
+
+### 修改文件 (6 个)
+
+```
+src/cli/bg.ts                          重构: handler 函数改为调用 BgEngine
+src/entrypoints/cli.tsx                快速路径: daemon 统一入口 + 向后兼容
+src/commands.ts                        注册 /daemon 和 /job 斜杠命令
+src/daemon/main.ts                     daemonMain() 增加 bg/ps/logs 子命令分发
+src/main.tsx                           Commander.js: 可选注册 daemon/job 子命令
+src/cli/handlers/templateJobs.ts       适配 /job 入口 (可能不需改)
+```
+
+### 不动的文件
+
+```
+src/daemon/state.ts                    daemon PID 状态管理 (无需改)
+src/jobs/state.ts                      job 状态管理 (无需改)
+src/jobs/templates.ts                  模板发现 (无需改)
+src/jobs/classifier.ts                 任务分类器 (无需改)
+src/cli/rollback.ts                    保持顶级命令 (无需改)
+src/cli/up.ts                          保持顶级命令 (无需改)
+```
+
+## 六、可行性分析
+
+### 6.1 风险评估
+
+| 风险 | 级别 | 缓解措施 |
+|------|------|---------|
+| cli.tsx 快速路径修改影响启动性能 | 低 | 仅改路由逻辑，import 仍然 lazy |
+| DetachedEngine 的 attach 在 Windows 上 fs.watch 不可靠 | 中 | 使用轮询 fallback (setInterval + fs.stat) |
+| 向后兼容的 deprecation 可能破坏脚本 | 低 | 旧命令保持可用，仅输出 stderr 警告 |
+| REPL 中 /daemon bg 需要 spawn 子进程 | 中 | 参考 /assistant 的 NewInstallWizard (已有 spawn 先例) |
+| tsc 类型兼容 | 低 | 接口定义清晰，不引入 any |
+
+### 6.2 工作量估计
+
+| Task | 文件数 | 复杂度 |
+|------|--------|--------|
+| Task 013: BgEngine 抽象 + 引擎实现 | 5 新增 + 1 修改 | 中 |
+| Task 014: /daemon 命令层级化 | 3 新增 + 3 修改 | 中 |
+| Task 015: /job 命令层级化 | 2 新增 + 2 修改 | 低 |
+| Task 016: 向后兼容 + 测试 | 0 新增 + 2 修改 | 低 |
+
+### 6.3 依赖关系
+
+```
+Task 013 (BgEngine) ← 无依赖，可独立开发
+Task 014 (/daemon)  ← 依赖 Task 013 (引擎选择)
+Task 015 (/job)     ← 无依赖，可与 013 并行
+Task 016 (兼容)     ← 依赖 Task 014 + 015
+```
+
+## 七、设计决策记录
+
+### D1: 为什么 daemon + bg sessions 合为一个命名空间？
+
+用户视角：都是"后台运行的东西"。分开会导致 `claude daemon status` 看 supervisor + `claude ps` 看会话，割裂感强。合并后 `claude daemon status` 一次性展示 supervisor 状态 + 所有会话列表。
+
+### D2: 为什么 rollback/up 不收入 daemon？
+
+它们本质是**版本管理/环境初始化**，不是后台进程管理。`claude up` 是同步阻塞的 setup 脚本，不涉及 daemon 或后台会话。保持顶级更直观。
+
+### D3: 为什么 DetachedEngine 的 attach 用 tail 而不是 IPC？
+
+1. 日志文件是最简单的跨平台方案，无需额外依赖
+2. UDS Pipe IPC 系统 (usePipeIpc) 设计用于实例间通信，不是终端附着
+3. tmux attach 的体验（完整 PTY）无法在纯 detached 模式下复制，tail 是最诚实的替代
+
+### D4: 为什么不用 Windows Terminal 的 tab/pane API？
+
+Windows Terminal 的 `wt.exe` 新窗口/标签功能不够通用——用户可能在 VS Code、ConEmu、cmder 等终端中。detached + log 是唯一跨终端方案。

+### 技术栈（v2，2026-04-18 重构）
+
+Web UI 已从原生 JS 重构为 **React + Vite + Radix UI**：
+
+- **框架**: React 19 + Vite 构建，TypeScript
+- **UI 组件**: Radix UI primitives（Dialog、Tabs、Select、Popover 等）
+- **聊天组件**: 完整的 ACP 聊天界面，支持 Plan 可视化、工具调用展示、权限审批
+- **AI Elements**: 独立的 AI 交互组件库（message、reasoning、tool、code-block、prompt-input 等）
+- **ACP 直连**: 支持 QR 码扫描自动跳转 ACP 直连视图（`ACPDirectView`）
+- **主题系统**: 暗色/亮色主题切换，遵循 Impeccable 设计系统
+
+### 功能
+
+- 查看已注册的运行环境（environment 模式），区分 ACP Agent 和 Claude Code 类型
 - 创建和管理会话
 - 实时查看对话消息和工具调用
+- 查看 Autopilot 状态（`standby` / `sleeping`）和自动运行指示
+- 查看 authoritative task snapshots 驱动的 Tasks 面板
 - 审批 Claude Code 的工具权限请求
+- 权限模式选择器（6 种模式：默认/自动接受编辑/跳过权限/规划/不询问/自动判断）
+- 模型选择器（可选可用模型）
+- Plan 可视化（进度条、状态图标、优先级标签）
+- ACP QR 扫描自动跳转到 ACP 聊天界面

+# Stub 恢复设计 1-4
+
+> 日期：2026-04-12
+> 目标：基于当前代码边界，为下一阶段 4 个 stub/半 stub 命令面给出可实施的设计方案。
+> 排序原则：按建议实施顺序排序，不按问题严重性排序。
+
+## 设计原则
+
+- 先做能独立闭环、收益明确、改动边界清晰的项。
+- 大项拆成 `MVP` 和 `Phase 2+`，避免一次性掉进大范围恢复。
+- 优先复用已有状态、传输层、日志与配置能力，不重造协议。
+- 设计以当前仓库实际代码为准，不以旧文档的理想状态为准。
+
+## 1. `claude daemon status` / `claude daemon stop`
+
+### 现状
+
+- `start` 路径已有完整 supervisor + worker 生命周期：
+  [src/daemon/main.ts](</e:/Source_code/Claude-code-bast/src/daemon/main.ts:1>)
+  [src/daemon/workerRegistry.ts](</e:/Source_code/Claude-code-bast/src/daemon/workerRegistry.ts:1>)
+- `status` / `stop` 目前只是占位输出：
+  [src/daemon/main.ts](</e:/Source_code/Claude-code-bast/src/daemon/main.ts:49>)
+- `/remote-control-server` 有自己的命令内 UI 状态，但只维护当前进程内的 `daemonProcess`，并不适合作为跨进程 CLI 管理基础：
+  [src/commands/remoteControlServer/remoteControlServer.tsx](</e:/Source_code/Claude-code-bast/src/commands/remoteControlServer/remoteControlServer.tsx:32>)
+
+### 目标
+
+- 让 `claude daemon status` 和 `claude daemon stop` 在另一个 CLI 进程中也能正确工作。
+- 不依赖 TUI 内存态，不要求当前命令进程就是启动 daemon 的那个进程。
+
+### MVP 方案
+
+- 新增 daemon 状态文件，例如：
+  `~/.claude/daemon/remote-control.json`
+- `start` 时写入：
+  - supervisor pid
+  - cwd
+  - startedAt
+  - worker kinds
+  - 最近状态
+- `status`：
+  - 读取状态文件
+  - 用现有进程探测能力验证 pid 是否存活
+  - 输出 `running / stopped / stale`
+  - stale 时自动清理状态文件
+- `stop`：
+  - 读取 pid
+  - 发送 `SIGTERM`
+  - 等待退出
+  - 超时后 `SIGKILL`
+  - 清理状态文件
+
+### 代码范围
+
+- 新增 `src/daemon/state.ts`
+- 修改 [src/daemon/main.ts](</e:/Source_code/Claude-code-bast/src/daemon/main.ts:1>)
+- 轻量修改 [src/commands/remoteControlServer/remoteControlServer.tsx](</e:/Source_code/Claude-code-bast/src/commands/remoteControlServer/remoteControlServer.tsx:32>)，让 UI 尽量读取同一份状态文件
+
+### 验证
+
+1. `claude daemon start`
+2. 新开终端执行 `claude daemon status`
+3. 执行 `claude daemon stop`
+4. 再次执行 `claude daemon status`，确认返回 `stopped` 或清晰的 `stale cleaned`
+
+### 风险
+
+- Windows 信号模型和 Unix 不同，`stop` 需要超时兜底。
+- 当前设计默认单 supervisor，不处理多实例并发。
+
+### 工作量判断
+
+- 小
+- 适合作为下一步的首选实现项
+
+## 2. `BG_SESSIONS`
+
+### 现状
+
+- fast-path 已接好：
+  [src/entrypoints/cli.tsx](</e:/Source_code/Claude-code-bast/src/entrypoints/cli.tsx:218>)
+- session registry 已有真实实现：
+  [src/utils/concurrentSessions.ts](</e:/Source_code/Claude-code-bast/src/utils/concurrentSessions.ts:1>)
+- `exit` 在 bg session 内已会 `tmux detach-client`：
+  [src/commands/exit/exit.tsx](</e:/Source_code/Claude-code-bast/src/commands/exit/exit.tsx:20>)
+- 但 CLI handler 仍全空：
+  [src/cli/bg.ts](</e:/Source_code/Claude-code-bast/src/cli/bg.ts:1>)
+- task summary 仍然是 stub：
+  [src/utils/taskSummary.ts](</e:/Source_code/Claude-code-bast/src/utils/taskSummary.ts:1>)
+
+### 目标
+
+- 先把 `ps` / `logs` / `kill` 做成真正有用的 session 管理命令。
+- 不在第一阶段就强行补完 `attach` / `--bg`。
+
+### Phase 2A：MVP
+
+- 实现 `ps`
+  - 从 registry 读取 live sessions
+  - 展示 pid、kind、sessionId、cwd、name、startedAt、bridgeSessionId
+  - 如果有 activity/status，则一并展示
+- 实现 `logs`
+  - 支持按 `sessionId / pid / name` 查找
+  - 优先复用本地 transcript/log 读取能力
+  - 如果 registry 里存在 `logPath`，支持 tail 文件
+- 实现 `kill`
+  - 解析目标 session
+  - 发退出信号
+  - 清理 stale registry
+
+### Phase 2B：后续
+
+- 实现 `attach`
+- 实现 `--bg`
+- 实现 `taskSummary` 的中途状态更新
+
+### 为什么要拆
+
+- 现有 registry 记录了 `pid / sessionId / name / logPath`
+- 但没有可靠的 tmux attach target
+- 所以 `attach` 和 `--bg` 不是简单补 handler，而是需要补启动/附着元数据设计
+
+### 代码范围
+
+- 修改 [src/cli/bg.ts](</e:/Source_code/Claude-code-bast/src/cli/bg.ts:1>)
+- 修改 [src/utils/concurrentSessions.ts](</e:/Source_code/Claude-code-bast/src/utils/concurrentSessions.ts:1>) 以便后续 attach/--bg 扩展
+- 修改 [src/utils/taskSummary.ts](</e:/Source_code/Claude-code-bast/src/utils/taskSummary.ts:1>)
+- 复用：
+  [src/utils/sessionStorage.ts](</e:/Source_code/Claude-code-bast/src/utils/sessionStorage.ts:3870>)
+  [src/utils/udsClient.ts](</e:/Source_code/Claude-code-bast/src/utils/udsClient.ts:1>)
+
+### 验证
+
+1. `ps` 能列出 live sessions
+2. `logs <sessionId|pid|name>` 能输出对应日志
+3. `kill <sessionId|pid|name>` 能结束目标 session
+
+### 风险
+
+- `attach` / `--bg` 第二阶段需要 tmux 元数据设计
+- Windows 下 tmux 路径需要明确降级策略
+
+### 工作量判断
+
+- `ps/logs/kill` 中等
+- `attach/--bg` 明显更大，应分阶段
+
+## 3. `TEMPLATES`
+
+### 现状
+
+- 命令入口只有 fast-path：
+  [src/entrypoints/cli.tsx](</e:/Source_code/Claude-code-bast/src/entrypoints/cli.tsx:249>)
+- handler 是空的：
+  [src/cli/handlers/templateJobs.ts](</e:/Source_code/Claude-code-bast/src/cli/handlers/templateJobs.ts:1>)
+- `markdownConfigLoader` 已把 `templates` 纳入配置目录：
+  [src/utils/markdownConfigLoader.ts](</e:/Source_code/Claude-code-bast/src/utils/markdownConfigLoader.ts:29>)
+- `query / stopHooks` 已预留 job classifier 链路：
+  [src/query/stopHooks.ts](</e:/Source_code/Claude-code-bast/src/query/stopHooks.ts:103>)
+- `jobs/classifier.ts` 仍是 stub：
+  [src/jobs/classifier.ts](</e:/Source_code/Claude-code-bast/src/jobs/classifier.ts:1>)
+
+### 目标
+
+- 把 `new / list / reply` 做成可用的模板任务系统。
+- 第一阶段不碰复杂的自动分类与自动执行。
+
+### MVP 方案
+
+- 模板来源：
+  `.claude/templates/*.md`
+- 模板格式：
+  复用现有 markdown + frontmatter 解析，不另外设计 DSL
+- `list`
+  - 列出所有模板
+  - 显示模板名、description、路径
+- `new <template> [args...]`
+  - 解析模板
+  - 在 `~/.claude/jobs/<job-id>/` 下创建 job 目录
+  - 写入 `template.md`、`input.txt`、`state.json`
+  - 返回 job id 与目录
+- `reply <job-id> <text>`
+  - 将回复写入 `replies.jsonl` 或 `input.txt`
+  - 更新 `state.json`
+
+### Phase 2
+
+- 恢复 [src/jobs/classifier.ts](</e:/Source_code/Claude-code-bast/src/jobs/classifier.ts:1>)
+- 让带 `CLAUDE_JOB_DIR` 的 job session 在 turn 完成后自动更新 `state.json`
+- 再决定是否补自动 job runner
+
+### 为什么要拆
+
+- 当前证据表明这是“template job commands”，不是单纯模板列表
+- 但自动 job 运行链路没有足够现成实现，先做文件系统 job lifecycle 更稳
+
+### 代码范围
+
+- 修改 [src/cli/handlers/templateJobs.ts](</e:/Source_code/Claude-code-bast/src/cli/handlers/templateJobs.ts:1>)
+- 新增 `src/jobs/state.ts`
+- 新增 `src/jobs/templates.ts`
+- Phase 2 再改 [src/jobs/classifier.ts](</e:/Source_code/Claude-code-bast/src/jobs/classifier.ts:1>)
+
+### 验证
+
+1. `list` 能列出 `.claude/templates`
+2. `new` 能创建 job 目录和状态文件
+3. `reply` 能更新 job 内容和状态
+4. Phase 2 再验证 classifier 写状态
+
+### 风险
+
+- frontmatter schema 需要先定义最小字段集
+- 一旦扩展到“自动运行 job”，范围会明显膨胀
+
+### 工作量判断
+
+- MVP 中等
+- 完整 job 系统偏大
+
+## 4. `assistant [sessionId]`
+
+### 现状
+
+- attach 主流程其实已经存在：
+  [src/main.tsx](</e:/Source_code/Claude-code-bast/src/main.tsx:4708>)
+- 远端 viewer 所需基础模块已存在：
+  [src/remote/RemoteSessionManager.ts](</e:/Source_code/Claude-code-bast/src/remote/RemoteSessionManager.ts:1>)
+  [src/hooks/useAssistantHistory.ts](</e:/Source_code/Claude-code-bast/src/hooks/useAssistantHistory.ts:1>)
+  [src/assistant/sessionHistory.ts](</e:/Source_code/Claude-code-bast/src/assistant/sessionHistory.ts:1>)
+- 真正 stub 的主要是：
+  [src/assistant/sessionDiscovery.ts](</e:/Source_code/Claude-code-bast/src/assistant/sessionDiscovery.ts:1>)
+  [src/assistant/AssistantSessionChooser.ts](</e:/Source_code/Claude-code-bast/src/assistant/AssistantSessionChooser.ts:1>)
+  [src/commands/assistant/assistant.ts](</e:/Source_code/Claude-code-bast/src/commands/assistant/assistant.ts:7>)
+  [src/assistant/index.ts](</e:/Source_code/Claude-code-bast/src/assistant/index.ts:1>)
+
+### 目标
+
+- 不一次性恢复整个 KAIROS 助手系统。
+- 先做“明确 sessionId 的 viewer attach 可用”，再逐步补 discovery / chooser / install。
+
+### Phase 4A：MVP
+
+- 只支持 `claude assistant <sessionId>`
+- 对 `claude assistant` 无参数模式，先返回明确提示：
+  - 当前版本需要显式 `sessionId`
+  - discovery 尚未启用
+- 这样可以直接复用现有 attach 分支，不必先恢复 chooser/install wizard
+
+### Phase 4B
+
+- 恢复 `discoverAssistantSessions()`
+- 数据来源优先复用现有 sessions / bridge / teleport API，而不是新协议
+- 让 `claude assistant` 无参数时能拿到候选 session 列表
+
+### Phase 4C
+
+- 恢复 `AssistantSessionChooser`
+- 多 session 时可交互选择
+
+### Phase 4D
+
+- 最后考虑 install wizard 辅助函数
+- 这部分属于“没有 session 时如何引导”，不是 attach 核心路径
+
+### 为什么要拆
+
+- attach 渲染层与远端消息通道大部分已经在
+- 真正缺的是“如何发现目标 session”和“如何交互选择”
+- 如果把 `src/assistant/index.ts` 的整套 KAIROS 正常模式也一起拉进来，范围会失控
+
+### 代码范围
+
+- Phase 4A：
+  - [src/main.tsx](</e:/Source_code/Claude-code-bast/src/main.tsx:4708>)
+  - [src/commands/assistant/index.ts](</e:/Source_code/Claude-code-bast/src/commands/assistant/index.ts:1>)
+- Phase 4B：
+  - [src/assistant/sessionDiscovery.ts](</e:/Source_code/Claude-code-bast/src/assistant/sessionDiscovery.ts:1>)
+- Phase 4C：
+  - [src/assistant/AssistantSessionChooser.ts](</e:/Source_code/Claude-code-bast/src/assistant/AssistantSessionChooser.ts:1>)
+- Phase 4D：
+  - [src/commands/assistant/assistant.ts](</e:/Source_code/Claude-code-bast/src/commands/assistant/assistant.ts:7>)
+
+### 验证
+
+1. `claude assistant <sessionId>` 能进入 remote viewer
+2. 历史懒加载工作正常
+3. 无参数模式先给出明确提示
+4. 后续阶段再分别验证 discovery / chooser / install
+
+### 风险
+
+- 这是四项里范围最大的
+- 一旦把 KAIROS 正常模式整体拉入，会从“viewer attach”膨胀成“完整 assistant mode 恢复”
+
+### 工作量判断
+
+- Phase 4A 中等
+- 4A-4D 全做完很大
+
+## 建议执行顺序
+
+1. `claude daemon status` / `claude daemon stop`
+2. `BG_SESSIONS` 先做 `ps/logs/kill`
+3. `TEMPLATES` 先做 job 文件系统 MVP
+4. `assistant [sessionId]` 先做显式 sessionId attach，再补 discovery/chooser/install
+
+## 简短结论
+
+这四项里，最适合立刻实现的是 `daemon status/stop`。`BG_SESSIONS` 和 `TEMPLATES` 适合按 MVP 先补 handler 与文件系统闭环。`assistant [sessionId]` 不能整块硬上，应该按“attach → discovery → chooser → install”拆开恢复。

+- [ ] `new <template> [args...]` 能创建 job 目录和状态文件
+- [ ] `reply <job-id> <text>` 能更新 job 内容和状态
+- [ ] frontmatter schema 最小字段集已定义
+
+## Phase 2 (后续)
+
+- [ ] 恢复 `src/jobs/classifier.ts`
+- [ ] 让带 `CLAUDE_JOB_DIR` 的 job session 在 turn 完成后自动更新 `state.json`
+- [ ] 再决定是否补自动 job runner
+
+### 为什么拆分
+
+- 当前是 "template job commands"，不是单纯模板列表
+- 自动 job 运行链路没有足够现成实现
+- 先做文件系统 job lifecycle 更稳
+
+## 风险
+
+- frontmatter schema 需要先定义最小字段集
+- 一旦扩展到"自动运行 job"，范围会明显膨胀
+
+## 依赖
+
+无硬性依赖，可独立实施。

+# Task 004: assistant [sessionId] — 分阶段恢复
+
+> 来源: [stub-recovery-design-1-4.md](../features/stub-recovery-design-1-4.md) 第 4 项
+> 优先级: P3
+> 工作量: Phase 4A 中等，4A-4D 全做完很大
+> 状态: Phase 4A DONE, 4B-4D TODO
+
+## 目标
+
+不一次性恢复整个 KAIROS 助手系统。先做"明确 sessionId 的 viewer attach 可用"，再逐步补 discovery / chooser / install。
+
+## 背景
+
+- attach 主流程已存在 (`src/main.tsx:4708`)
+- 远端 viewer 所需基础模块已存在:
+  - `src/remote/RemoteSessionManager.ts`
+  - `src/hooks/useAssistantHistory.ts`
+  - `src/assistant/sessionHistory.ts`
+- 真正 stub 的主要是:
+  - `src/assistant/sessionDiscovery.ts`
+  - `src/assistant/AssistantSessionChooser.ts`
+  - `src/commands/assistant/assistant.ts:7`
+  - `src/assistant/index.ts`
+
+## 分阶段实现
+
+### Phase 4A: MVP — 显式 sessionId attach
+
+**修改文件:**
+
+| 文件 | 改动 |
+|------|------|
+| `src/main.tsx` | 确保 attach 分支可用 |
+| `src/commands/assistant/index.ts` | 实现显式 sessionId 参数入口 |
+
+**行为:**
+- `claude assistant <sessionId>` — 进入 remote viewer
+- `claude assistant` (无参数) — 返回明确提示: 当前版本需要显式 sessionId，discovery 尚未启用
+
+**验证:**
+- [ ] `claude assistant <sessionId>` 能进入 remote viewer
+- [ ] 历史懒加载工作正常
+- [ ] 无参数模式给出明确提示
+
+### Phase 4B: session discovery
+
+**修改文件:**
+
+| 文件 | 改动 |
+|------|------|
+| `src/assistant/sessionDiscovery.ts` | 恢复 `discoverAssistantSessions()` |
+
+**行为:**
+- 数据来源优先复用现有 sessions / bridge / teleport API，不新增协议
+- `claude assistant` 无参数时能拿到候选 session 列表
+
+**验证:**
+- [ ] 无参数调用能列出可用 sessions
+- [ ] 数据来源复用现有通道
+
+### Phase 4C: session chooser
+
+**修改文件:**
+
+| 文件 | 改动 |
+|------|------|
+| `src/assistant/AssistantSessionChooser.ts` | 恢复交互式选择器 |
+
+**行为:**
+- 多 session 时可交互选择
+
+**验证:**
+- [ ] 多个 session 时弹出选择器
+- [ ] 选择后正确 attach
+
+### Phase 4D: install wizard
+
+**修改文件:**
+
+| 文件 | 改动 |
+|------|------|
+| `src/commands/assistant/assistant.ts` | 恢复 install wizard 辅助函数 |
+
+**行为:**
+- 没有 session 时如何引导用户
+
+**验证:**
+- [ ] 无可用 session 时引导用户创建/连接
+
+## 为什么拆分
+
+- attach 渲染层与远端消息通道大部分已在
+- 真正缺的是"如何发现目标 session"和"如何交互选择"
+- 如果把 `src/assistant/index.ts` 的整套 KAIROS 正常模式也一起拉进来，范围会失控
+
+## 风险
+
+- 这是四项里范围最大的
+- 一旦把 KAIROS 正常模式整体拉入，会从"viewer attach"膨胀成"完整 assistant mode 恢复"
+
+## 依赖
+
+- Task 002 的 session registry 模式可复用

+# Task 013: BgEngine 跨平台后台引擎抽象
+
+> 设计文档: [daemon-restructure-design.md](../features/daemon-restructure-design.md) § 四
+> 依赖: 无
+> 分支: `feat/integrate-5-branches`
+
+## 目标
+
+将 `src/cli/bg.ts` 中硬编码的 tmux 逻辑提取为引擎抽象层，实现 TmuxEngine + DetachedEngine，使后台会话功能在 Windows / macOS / Linux 上都能工作。
+
+## 背景
+
+当前 `bg.ts` 中 `handleBgFlag()` 和 `attachHandler()` 直接调用 tmux 命令。Windows 上 `--bg` 直接报错退出。需要一个引擎抽象层，根据平台和可用工具自动选择最佳方案。
+
+## 文件清单
+
+### 新增
+
+| 文件 | 说明 |
+|------|------|
+| `src/cli/bg/engine.ts` | BgEngine 接口 + BgStartOptions/BgStartResult 类型 |
+| `src/cli/bg/engines/tmux.ts` | TmuxEngine: 从 `bg.ts` 提取 tmux 相关逻辑 |
+| `src/cli/bg/engines/detached.ts` | DetachedEngine: spawn({ detached }) + logFile 重定向 |
+| `src/cli/bg/engines/index.ts` | selectEngine() 自动选择 + re-export |
+| `src/cli/bg/tail.ts` | 跨平台日志 tail: fs.watch + 轮询 fallback |
+
+### 修改
+
+| 文件 | 变更 |
+|------|------|
+| `src/cli/bg.ts` | `handleBgFlag()` 改为调用 `selectEngine().start()`；`attachHandler()` 改为调用 `engine.attach()` |
+
+## 实现方案
+
+### 1. BgEngine 接口 (`src/cli/bg/engine.ts`)
+
+```typescript
+export interface BgEngine {
+  readonly name: string
+  available(): Promise<boolean>
+  start(opts: BgStartOptions): Promise<BgStartResult>
+  attach(session: SessionEntry): Promise<void>
+}
+
+export interface BgStartOptions {
+  sessionName: string
+  args: string[]         // CLI args (去除 --bg)
+  env: Record<string, string | undefined>
+  logPath: string
+  cwd: string
+}
+
+export interface BgStartResult {
+  pid: number
+  sessionName: string
+  logPath: string
+  engineUsed: 'tmux' | 'detached'
+}
+```
+
+### 2. TmuxEngine (`src/cli/bg/engines/tmux.ts`)
+
+从 `bg.ts:handleBgFlag()` 和 `bg.ts:attachHandler()` 提取:
+- `available()`: `execFileNoThrow('tmux', ['-V'])` 返回 code === 0
+- `start()`: `tmux new-session -d -s <name> <cmd>`
+- `attach()`: `tmux attach-session -t <session.tmuxSessionName>`
+
+### 3. DetachedEngine (`src/cli/bg/engines/detached.ts`)
+
+```typescript
+export class DetachedEngine implements BgEngine {
+  readonly name = 'detached'
+
+  async available(): Promise<boolean> {
+    return true  // 总是可用
+  }
+
+  async start(opts: BgStartOptions): Promise<BgStartResult> {
+    const logFd = openSync(opts.logPath, 'a')
+    const child = spawn(process.execPath, [process.argv[1]!, ...opts.args], {
+      detached: true,
+      stdio: ['ignore', logFd, logFd],
+      env: opts.env,
+      cwd: opts.cwd,
+    })
+    child.unref()
+    closeSync(logFd)
+
+    return {
+      pid: child.pid!,
+      sessionName: opts.sessionName,
+      logPath: opts.logPath,
+      engineUsed: 'detached',
+    }
+  }
+
+  async attach(session: SessionEntry): Promise<void> {
+    // 委托给 tail.ts
+    await tailLog(session.logPath!)
+  }
+}
+```
+
+### 4. 日志 Tail (`src/cli/bg/tail.ts`)
+
+```typescript
+/**
+ * 跨平台实时日志输出。Ctrl+C 退出，不杀后台进程。
+ *
+ * 策略:
+ * 1. 读取已有内容输出
+ * 2. fs.watch() 监听文件变化 (主方案)
+ * 3. 如果 fs.watch 不可靠 (某些 Windows 网络驱动器)，fallback 到 500ms 轮询
+ */
+export async function tailLog(logPath: string): Promise<void>
+```
+
+### 5. 引擎选择 (`src/cli/bg/engines/index.ts`)
+
+```typescript
+export async function selectEngine(): Promise<BgEngine> {
+  if (process.platform === 'win32') {
+    return new DetachedEngine()
+  }
+  const tmux = new TmuxEngine()
+  if (await tmux.available()) {
+    return tmux
+  }
+  return new DetachedEngine()
+}
+```
+
+### 6. bg.ts 重构
+
+`handleBgFlag()` 改名为 `handleBgStart()`，内部逻辑:
+```typescript
+export async function handleBgStart(args: string[]): Promise<void> {
+  const engine = await selectEngine()
+  const sessionName = `claude-bg-${randomUUID().slice(0, 8)}`
+  const logPath = join(getClaudeConfigHomeDir(), 'sessions', 'logs', `${sessionName}.log`)
+
+  const result = await engine.start({
+    sessionName,
+    args: filteredArgs,
+    env: { ...process.env, CLAUDE_CODE_SESSION_KIND: 'bg', ... },
+    logPath,
+    cwd: process.cwd(),
+  })
+
+  console.log(`Background session started: ${result.sessionName}`)
+  console.log(`  Engine: ${result.engineUsed}`)
+  console.log(`  Log: ${result.logPath}`)
+  console.log(`  Use \`claude daemon attach ${result.sessionName}\` to reconnect.`)
+}
+```
+
+`attachHandler()` 根据 `session.engine` 字段选择引擎:
+```typescript
+export async function attachHandler(target: string | undefined): Promise<void> {
+  // ... 找到 session
+  if (session.engine === 'tmux' && session.tmuxSessionName) {
+    const tmux = new TmuxEngine()
+    await tmux.attach(session)
+  } else {
+    const detached = new DetachedEngine()
+    await detached.attach(session)
+  }
+}
+```
+
+## SessionEntry 扩展
+
+`sessions/<PID>.json` 新增 `engine` 字段:
+
+```json
+{
+  "pid": 12345,
+  "engine": "detached",
+  "logPath": "~/.claude/sessions/logs/claude-bg-a1b2c3d4.log",
+  "sessionId": "...",
+  "cwd": "..."
+}
+```
+
+兼容旧格式: 如果 `engine` 字段缺失，检查 `tmuxSessionName` 存在则为 `tmux`，否则为 `detached`。
+
+## 验证清单
+
+- [ ] Windows: `claude daemon bg` 启动后台会话，无 tmux 依赖

+## 目标
+
+将散落的 `daemon start/stop/status` + `ps/logs/attach/kill` + `--bg` 统一收归 `/daemon` 命名空间，实现 CLI + REPL 双注册。
+
+## 背景
+
+当前这些命令注册在两个互不关联的位置:
+- `cli.tsx:203-212`: `daemon [start|status|stop]` → `daemon/main.ts`
+- `cli.tsx:217-246`: `ps|logs|attach|kill|--bg` → `cli/bg.ts`
+
+需要合并为统一的 `claude daemon <subcommand>` 入口，并新增 REPL `/daemon` 斜杠命令。
+
+## 文件清单
+
+### 新增
+
+| 文件 | 说明 |
+|------|------|
+| `src/commands/daemon/index.ts` | `/daemon` REPL 斜杠命令注册 (type: local-jsx) |
+| `src/commands/daemon/daemon.tsx` | `/daemon` 子命令路由 + status UI 组件 |
+
+### 修改
+
+| 文件 | 变更 |
+|------|------|
+| `src/entrypoints/cli.tsx` | 统一 daemon 快速路径: `daemon <sub>` 路由到对应 handler。旧命令 `ps/logs/attach/kill` 保留但输出 deprecation 警告后代理 |
+| `src/commands.ts` | 注册 `/daemon` 斜杠命令 (feature-gated: DAEMON \|\| BG_SESSIONS) |
+| `src/daemon/main.ts` | `daemonMain()` 扩展: 支持 `bg/attach/logs/kill/ps` 子命令 (委托给 bg.ts handlers) |
+
+## 实现方案
+
+### 1. CLI 快速路径统一 (`cli.tsx`)
+
+**改前** (两段独立路由):
+```typescript
+// 段 1: daemon
+if (feature('DAEMON') && args[0] === 'daemon') {
+  await daemonMain(args.slice(1))
+}
+// 段 2: bg sessions
+if (feature('BG_SESSIONS') && ['ps','logs','attach','kill'].includes(args[0])) {
+  // ...switch/case
+}
+```
+
+**改后** (统一入口):
+```typescript
+// 统一 daemon 入口 — 合并 daemon supervisor + bg sessions
+if (
+  (feature('DAEMON') || feature('BG_SESSIONS')) &&
+  args[0] === 'daemon'
+) {
+  profileCheckpoint('cli_daemon_path')
+  const { enableConfigs } = await import('../utils/config.js')
+  enableConfigs()
+  const { initSinks } = await import('../utils/sinks.js')
+  initSinks()
+  const { daemonMain } = await import('../daemon/main.js')
+  await daemonMain(args.slice(1))
+  return
+}
+
+// --bg 快捷方式 → daemon bg
+if (
+  feature('BG_SESSIONS') &&
+  (args.includes('--bg') || args.includes('--background'))
+) {
+  profileCheckpoint('cli_daemon_path')
+  const { enableConfigs } = await import('../utils/config.js')
+  enableConfigs()
+  const bg = await import('../cli/bg.js')
+  await bg.handleBgStart(args.filter(a => a !== '--bg' && a !== '--background'))
+  return
+}
+
+// 向后兼容: ps/logs/attach/kill → daemon <sub> (deprecated)
+if (
+  feature('BG_SESSIONS') &&
+  ['ps', 'logs', 'attach', 'kill'].includes(args[0] ?? '')
+) {
+  const mapped = args[0] === 'ps' ? 'status' : args[0]
+  console.error(`[deprecated] Use: claude daemon ${mapped} ${args.slice(1).join(' ')}`.trim())
+  const { enableConfigs } = await import('../utils/config.js')
+  enableConfigs()
+  const { daemonMain } = await import('../daemon/main.js')
+  await daemonMain([args[0]!, ...args.slice(1)])
+  return
+}
+```
+
+### 2. daemonMain 扩展 (`daemon/main.ts`)
+
+```typescript
+export async function daemonMain(args: string[]): Promise<void> {
+  const subcommand = args[0] || 'status'
+
+  switch (subcommand) {
+    // --- Supervisor 管理 ---
+    case 'start':
+      await runSupervisor(args.slice(1))
+      break
+    case 'stop':
+      await handleDaemonStop()
+      break
+
+    // --- 会话管理 (委托给 bg.ts) ---
+    case 'status':
+    case 'ps':
+      await showUnifiedStatus()  // 新: daemon 状态 + 会话列表
+      break
+    case 'bg':
+      const bg = await import('../cli/bg.js')
+      await bg.handleBgStart(args.slice(1))
+      break
+    case 'attach':
+      const bg2 = await import('../cli/bg.js')
+      await bg2.attachHandler(args[1])
+      break
+    case 'logs':
+      const bg3 = await import('../cli/bg.js')
+      await bg3.logsHandler(args[1])
+      break
+    case 'kill':
+      const bg4 = await import('../cli/bg.js')
+      await bg4.killHandler(args[1])
+      break
+
+    case '--help': case '-h': case 'help':
+      printHelp()
+      break
+    default:
+      console.error(`Unknown daemon subcommand: ${subcommand}`)
+      printHelp()
+      process.exitCode = 1
+  }
+}
+```
+
+### 3. 统一状态面板 (`showUnifiedStatus`)
+
+```typescript
+async function showUnifiedStatus(): Promise<void> {
+  // 1. Daemon supervisor 状态
+  const daemonResult = queryDaemonStatus()
+  console.log('=== Daemon Supervisor ===')
+  switch (daemonResult.status) {
+    case 'running':
+      console.log(`  Status: running (PID: ${daemonResult.state!.pid})`)
+      console.log(`  Workers: ${daemonResult.state!.workerKinds.join(', ')}`)
+      break
+    case 'stopped':
+      console.log('  Status: stopped')
+      break
+    case 'stale':
+      console.log('  Status: stale (cleaned up)')
+      break
+  }
+
+  // 2. 后台会话列表
+  console.log('\n=== Background Sessions ===')
+  const bg = await import('../cli/bg.js')
+  await bg.psHandler([])
+}
+```
+
+### 4. REPL 斜杠命令注册
+
+**`src/commands/daemon/index.ts`**:
+```typescript
+import type { Command } from '../../commands.js'
+import { feature } from 'bun:bundle'
+
+const daemon = {
+  type: 'local-jsx',
+  name: 'daemon',
+  description: 'Manage background sessions and daemon',
+  argumentHint: '[status|start|stop|bg|attach|logs|kill]',
+  isEnabled: () => {
+    if (feature('DAEMON')) return true
+    if (feature('BG_SESSIONS')) return true
+    return false
+  },
+  load: () => import('./daemon.js'),
+} satisfies Command
+
+export default daemon
+```
+
+**`src/commands/daemon/daemon.tsx`**:
+```typescript
+export async function call(
+  onDone: LocalJSXCommandOnDone,
+  context: LocalJSXCommandContext,
+  args: string,
+): Promise<React.ReactNode> {
+  const parts = args.trim().split(/\s+/)
+  const sub = parts[0] || 'status'
+
+  switch (sub) {
+    case 'status':
+    case 'ps':
+      // 调用 showUnifiedStatus，捕获输出
+      // 返回文本结果
+      break
+    case 'bg':
+      // REPL 中启动后台会话
+      break
+    case 'start':
+    case 'stop':
+    case 'attach':
+    case 'logs':
+    case 'kill':
+      // 委托给对应 handler
+      break
+    default:
+      onDone(`Unknown: ${sub}. Use: status|start|stop|bg|attach|logs|kill`)
+      return null
+  }
+}
+```
+
+**`src/commands.ts`** 添加:
+```typescript
+// 条件导入
+const daemonCmd =
+  feature('DAEMON') || feature('BG_SESSIONS')
+    ? require('./commands/daemon/index.js').default
+    : null
+
+// COMMANDS 数组中添加
+...(daemonCmd ? [daemonCmd] : []),
+```
+
+### 5. 更新 help 文本 (`daemon/main.ts`)
+
+```
+Claude Code Daemon — background process management
+
+USAGE
+  claude daemon [subcommand]
+
+SUBCOMMANDS
+  status      Show daemon and session status (default)

+
+## 目标
+
+将 `claude new/list/reply` 收归 `/job` 命名空间，实现 CLI + REPL 双注册。
+
+## 背景
+
+当前 `new`, `list`, `reply` 是顶级 CLI 命令 (`cli.tsx:250-261`)，容易与其他命令冲突（特别是 `list` 这种通用词）。需要收归 `claude job <subcommand>` 并新增 REPL `/job` 入口。
+
+## 文件清单
+
+### 新增
+
+| 文件 | 说明 |
+|------|------|
+| `src/commands/job/index.ts` | `/job` REPL 斜杠命令注册 |
+| `src/commands/job/job.tsx` | `/job` 子命令路由 |
+
+### 修改
+
+| 文件 | 变更 |
+|------|------|
+| `src/entrypoints/cli.tsx` | 新增 `job` 快速路径 + 旧 `new/list/reply` deprecation 代理 |
+| `src/commands.ts` | 注册 `/job` 斜杠命令 |
+
+### 不动
+
+| 文件 | 说明 |
+|------|------|
+| `src/cli/handlers/templateJobs.ts` | 内部 handler 不变，只是被调用方式变了 |
+| `src/jobs/state.ts` | job 状态管理不变 |
+| `src/jobs/templates.ts` | 模板发现不变 |
+| `src/jobs/classifier.ts` | 任务分类器不变 |
+
+## 实现方案
+
+### 1. CLI 快速路径 (`cli.tsx`)
+
+**改后**:
+```typescript
+// 新: claude job <subcommand>
+if (
+  feature('TEMPLATES') &&
+  args[0] === 'job'
+) {
+  profileCheckpoint('cli_templates_path')
+  const { templatesMain } = await import('../cli/handlers/templateJobs.js')
+  await templatesMain(args.slice(1))

+  profileCheckpoint('cli_templates_path')
+  const { templatesMain } = await import('../cli/handlers/templateJobs.js')
+  await templatesMain(args)
+  process.exit(0)
+}
+```
+
+### 2. templateJobs.ts 新增 status 子命令
+
+在现有 `switch` 中增加:
+```typescript
+case 'status':
+  handleStatus(args.slice(1))
+  break
+```
+
+```typescript
+function handleStatus(args: string[]): void {
+  const jobId = args[0]
+  if (!jobId) {
+    console.error('Usage: claude job status <job-id>')
+    process.exitCode = 1
+    return
+  }
+  const state = readJobState(jobId)
+  if (!state) {
+    console.error(`Job not found: ${jobId}`)
+    process.exitCode = 1
+    return
+  }
+  console.log(`Job: ${state.jobId}`)
+  console.log(`  Template: ${state.templateName}`)
+  console.log(`  Status: ${state.status}`)
+  console.log(`  Created: ${state.createdAt}`)
+  console.log(`  Updated: ${state.updatedAt}`)
+}
+```
+
+### 3. REPL 斜杠命令
+
+**`src/commands/job/index.ts`**:
+```typescript
+import type { Command } from '../../commands.js'
+import { feature } from 'bun:bundle'
+
+const job = {
+  type: 'local-jsx',

+# Task 016: 向后兼容 + 测试
+
+> 设计文档: [daemon-restructure-design.md](../features/daemon-restructure-design.md) § 五
+> 依赖: Task 014, Task 015
+> 分支: `feat/integrate-5-branches`
+
+## 目标
+
+确保旧命令向后兼容 (deprecation 警告 + 正常代理)，并为重构后的命令结构编写测试。
+
+## 文件清单
+
+### 新增
+
+| 文件 | 说明 |
+|------|------|
+| `src/daemon/__tests__/daemonMain.test.ts` | daemonMain 子命令路由测试 |
+| `src/cli/bg/__tests__/engine.test.ts` | BgEngine 选择逻辑测试 |
+| `src/cli/bg/__tests__/detached.test.ts` | DetachedEngine 启动/停止测试 |
+| `src/cli/bg/__tests__/tail.test.ts` | 日志 tail 功能测试 |
+
+### 修改
+
+| 文件 | 变更 |
+|------|------|
+| `src/entrypoints/cli.tsx` | 确认 deprecation 路径正确代理 |
+
+## 实现方案
+
+### 1. 向后兼容矩阵
+
+| 旧命令 | 新命令 | 处理方式 |
+|--------|--------|---------|
+| `claude ps` | `claude daemon status` | stderr 输出 `[deprecated] Use: claude daemon status`，然后执行 |
+| `claude logs <x>` | `claude daemon logs <x>` | 同上 |
+| `claude attach <x>` | `claude daemon attach <x>` | 同上 |
+| `claude kill <x>` | `claude daemon kill <x>` | 同上 |
+| `claude --bg` | `claude daemon bg` | 保留为快捷方式，**不** deprecate (太常用) |
+| `claude new <t>` | `claude job new <t>` | stderr deprecation + 执行 |
+| `claude list` | `claude job list` | stderr deprecation + 执行 |
+| `claude reply <id>` | `claude job reply <id>` | stderr deprecation + 执行 |
+
+**关键**: deprecation 输出到 stderr 而非 stdout，不影响脚本管道。
+
+### 2. 测试计划
+
+#### 2.1 daemonMain 路由测试
+
+```typescript
+describe('daemonMain', () => {
+  test('无参数默认 status', async () => { ... })
+  test('start 调用 runSupervisor', async () => { ... })
+  test('stop 调用 handleDaemonStop', async () => { ... })
+  test('bg 委托给 bg.handleBgStart', async () => { ... })
+  test('attach 委托给 bg.attachHandler', async () => { ... })
+  test('logs 委托给 bg.logsHandler', async () => { ... })
+  test('kill 委托给 bg.killHandler', async () => { ... })
+  test('未知子命令设置 exitCode=1', async () => { ... })
+})
+```
+
+#### 2.2 引擎选择测试
+
+```typescript
+describe('selectEngine', () => {
+  test('win32 返回 DetachedEngine', async () => { ... })
+  test('darwin + tmux 可用返回 TmuxEngine', async () => { ... })
+  test('darwin + tmux 不可用返回 DetachedEngine', async () => { ... })
+  test('linux + tmux 可用返回 TmuxEngine', async () => { ... })
+})
+```
+
+#### 2.3 DetachedEngine 测试
+
+```typescript
+describe('DetachedEngine', () => {
+  test('available 始终返回 true', async () => { ... })
+  test('start 创建 detached 子进程并写入日志', async () => { ... })
+  test('start 返回的 PID 文件存在', async () => { ... })
+})
+```
+
+#### 2.4 Tail 测试
+
+```typescript
+describe('tailLog', () => {
+  test('输出已有日志内容', async () => { ... })
+  test('追加内容时实时输出', async () => { ... })
+  test('SIGINT 退出 tail', async () => { ... })
+})
+```
+
+### 3. 集成验证脚本
+
+可选: 在 `scripts/` 下添加一个手动验证脚本:
+
+```bash
+#!/bin/bash
+# scripts/verify-daemon-restructure.sh
+echo "=== 1. claude daemon status ==="
+bun run dev -- daemon status
+
+echo "=== 2. claude daemon bg (should start) ==="
+bun run dev -- daemon bg --help
+
+echo "=== 3. claude ps (deprecated) ==="
+bun run dev -- ps 2>&1 | head -1
+
+echo "=== 4. claude job list ==="
+bun run dev -- job list
+
+echo "=== 5. claude list (deprecated) ==="
+bun run dev -- list 2>&1 | head -1
+```
+
+## 验证清单
+
+- [ ] 旧命令全部正常工作 (仅多一行 stderr 警告)
+- [ ] `--bg` 保持无警告
+- [ ] 所有新增测试通过
+- [ ] 现有 2695 个测试无回归
+- [ ] tsc --noEmit 零错误
+- [ ] 手动在 Windows + macOS/Linux 上验证关键路径

+# OpenClaw Autonomy Baseline Test Spec
+
+## Purpose
+
+This test spec locks the current behavior of the existing trigger and context layers before any formal autonomy-subsystem implementation begins.
+
+At this stage, production code is read-only. Only test files, fixtures, and planning documents may change.
+
+## Goal
+
+Establish a stable baseline around the parts of `Claude-code-bast` that later autonomy work is most likely to touch:
+
+- proactive state handling
+- cron task storage semantics
+- cron scheduler helper semantics
+- user-context cache and `CLAUDE.md` injection behavior
+
+## Out of Scope for This Baseline Round
+
+- New authority behavior (`AGENTS.md` / `HEARTBEAT.md`)
+- New detached-run ledger behavior
+- New flow behavior
+- UI redesign
+
+## Files Under Baseline Protection
+
+- `src/proactive/index.ts`
+- `src/utils/cronTasks.ts`
+- `src/utils/cronScheduler.ts`
+- `src/context.ts`
+
+## Test Files Added In This Round
+
+- `src/proactive/__tests__/state.baseline.test.ts`
+- `src/commands/__tests__/proactive.baseline.test.ts`
+- `src/utils/__tests__/cronTasks.baseline.test.ts`
+- `src/utils/__tests__/cronScheduler.baseline.test.ts`
+- `src/__tests__/context.baseline.test.ts`
+
+## Baseline Assertions
+
+### Proactive state
+
+1. Activating proactive mode sets active state and activation source.
+2. Pausing proactive mode suppresses `shouldTick()` and clears `nextTickAt`.
+3. Blocking context suppresses `shouldTick()` and clears `nextTickAt`.
+4. Subscribers are notified on state transitions.
+5. The `/proactive` command enables proactive mode and emits the expected hidden reminder.
+6. The `/proactive` command disables proactive mode on the second invocation.
+
+### Cron task storage
+
+1. Session-only cron tasks remain in memory only.
+2. Durable cron tasks are persisted to `.claude/scheduled_tasks.json`.
+3. Daemon-style `dir`-scoped reads exclude session-only cron tasks.
+4. `removeCronTasks()` without `dir` can remove session-only tasks.
+5. `removeCronTasks()` with `dir` does not mutate session-only task storage.
+
+### Cron scheduler helpers
+
+1. `isRecurringTaskAged()` preserves current aging semantics.
+2. `buildMissedTaskNotification()` preserves the current AskUserQuestion safety wording.
+3. `buildMissedTaskNotification()` preserves code-fence hardening for prompt bodies that contain backticks.
+
+### User context caching
+
+1. `getUserContext()` includes `currentDate`.
+2. `getUserContext()` includes mocked `claudeMd` content when memory loading is enabled.
+3. `CLAUDE_CODE_DISABLE_CLAUDE_MDS` suppresses `claudeMd`.
+4. `setSystemPromptInjection()` clears the memoized user-context cache.
+5. `getSystemContext()` reflects the injection after cache invalidation.
+
+## Remaining Baseline Gaps
+
+The following areas are intentionally deferred because they require higher-cost harnessing and should still avoid production-code changes:
+
+1. `useScheduledTasks.ts` hook-level runtime behavior
+2. `src/cli/print.ts` full headless scheduler loop behavior
+3. `useProactive.ts` hook timer behavior
+4. end-to-end queue interaction between proactive ticks and `SleepTool`
+
+## Acceptance
+
+This baseline round is complete when:
+
+1. The four new test files pass.
+2. No production source files are modified.
+3. The tests are stable enough to serve as a pre-implementation guardrail.

+ARGUMENTS
+  command...  Agent command followed by its arguments
+```
+
+## How It Works
+
+1. Listens for WebSocket connections from clients
+2. When a "connect" message is received, spawns the configured ACP agent as a subprocess
+3. Bridges messages between the WebSocket (client) and stdin/stdout (agent via ACP protocol)
+4. Supports session management: create, load, resume, list sessions
+5. Handles permission approval flow and heartbeat keepalive
+
+## Authentication
+
+By default, a random token is auto-generated on startup. Pass it as a query parameter:
+
+```
+ws://localhost:9315/ws?token=<your-token>
+```
+
+Set `ACP_AUTH_TOKEN` env var to use a fixed token, or use `--no-auth` to disable (not recommended).
