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

* 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

* 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

* docs: 更新文档及说明

* fix: 修复类型错误

* chore: 提交脚本

+# 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

-# KAIROS — 永不关机的 Claude
-
-> 源码位置：`src/assistant/`、`src/proactive/`、`src/services/autoDream/`
-> 编译开关：`feature('KAIROS')`、`feature('KAIROS_BRIEF')`、`feature('KAIROS_CHANNELS')`
-> 远程开关：GrowthBook `tengu_kairos`
-
-关掉终端 Claude 还在运行的持久助手模式。KAIROS 是 Claude Code 中最复杂的隐藏功能之一。
-
----
-
-## 核心概念
-
-KAIROS 让 Claude 从"一次性对话工具"变成"持久运行的 AI 助手"：
-
-- 关闭终端后 Claude 仍在后台运行
-- 每天自动写日志
-- 晚上自动"做梦"整理记忆
-- 没人说话时自己找活干
-- 命令超 15 秒自动丢后台
-
----
-
-## 激活流程
-
-定义在 `src/main.tsx`（约第 1054-1092 行），需要通过五层检查：
-
-```
-1. feature('KAIROS')          ← 编译时 flag
-2. settings.assistant: true   ← .claude/settings.json
-3. 目录信任状态检查            ← 防恶意仓库劫持
-4. tengu_kairos               ← GrowthBook 远程开关
-5. setKairosActive(true)      ← 全局状态激活
-```
-
-`--assistant` CLI 参数可跳过远程开关检查（用于 Agent SDK daemon 模式）。
-
-全局状态存储在 `src/bootstrap/state.ts`：
-- `kairosActive: boolean`（默认 `false`）
-- `getKairosActive()` / `setKairosActive(true)`
-
----
-
-## 跨会话持久运行
-
-### 会话恢复
-
-`src/utils/conversationRecovery.ts` 中使用 `feature('KAIROS')` 条件导入 `BriefTool` 和 `SendUserFileTool`。在反序列化会话时识别这些工具的结果为"终端工具结果"，判断 turn 是正常完成还是被中断。
-
-### 持久 Cron 任务
-
-关键在 `.claude/scheduled_tasks.json`。标记为 `permanent: true` 的任务不受 7 天自动过期限制：
-
-- `catch-up`：恢复中断的工作
-- `morning-checkin`：每日早间签到
-- `dream`：记忆整合
-
-### 会话历史 API
-
-`src/assistant/sessionHistory.ts` 通过 OAuth API 加载远程会话历史，使用 `v1/sessions/{sessionId}/events` 端点，支持分页拉取。
-
----
-
-## 做梦机制（Dream）
-
-KAIROS 最精巧的子系统——后台运行的子代理，将分散的会话记忆整合为持久的结构化知识。
-
-### 触发条件（三层门控，由廉到贵）
-
-定义在 `src/services/autoDream/autoDream.ts`：
-
-```
-1. 时间门控：距上次整合超过 24 小时（minHours）
-2. 会话门控：至少 5 个新会话（minSessions）
-3. 锁门控：没有其他进程正在整合
-```
-
-阈值通过 GrowthBook `tengu_onyx_plover` 远程配置动态控制。
-
-### 四阶段整合流程
-
-定义在 `src/services/autoDream/consolidationPrompt.ts`：
-
-| 阶段 | 动作 |
-|------|------|
-| **Orient** | 列出记忆目录、读取 `MEMORY.md` 索引、浏览已有主题文件 |
-| **Gather** | 从每日日志、已有记忆、JSONL transcript 中搜集新信号 |
-| **Consolidate** | 合并新信号到主题文件，转换相对日期为绝对日期，删除过时事实 |
-| **Prune** | 更新 `MEMORY.md` 索引，保持在行数和大小限制内 |
-
-### 锁机制
-
-`src/services/autoDream/consolidationLock.ts`：
-
-- 使用 `.consolidate-lock` 文件
-- 文件 mtime = `lastConsolidatedAt`
-- 文件内容 = 持有者 PID
-- 支持 PID 存活检查（1 小时超时）
-- double-write 后 re-read 验证防竞争
-
-### 每日日志
-
-路径由 `src/memdir/paths.ts` 的 `getAutoMemDailyLogPath()` 计算：
-
-```
-<autoMemPath>/logs/YYYY/MM/YYYY-MM-DD.md
-```
-
-### UI 呈现
-
-- Footer pill 标签显示 **"dreaming"**
-- `src/components/tasks/DreamDetailDialog.tsx` 提供专门的详情对话框
-- 支持查看实时进度和手动中止
-- `Shift+Down` 打开后台任务对话框
-
----
-
-## 主动模式（Proactive Mode）
-
-没人说话时 Claude 自己找活干。
-
-### 核心状态
-
-`src/proactive/index.ts` 维护三个状态：
-
-| 状态 | 说明 |
-|------|------|
-| `active` | 是否激活 |
-| `paused` | 是否暂停（用户按 Esc 取消时暂停，下次输入恢复） |
-| `contextBlocked` | API 错误时阻塞 tick，防止 tick-error-tick 死循环 |
-
-### 激活方式
-
-- `--proactive` CLI 参数
-- `CLAUDE_CODE_PROACTIVE` 环境变量
-- 受 `feature('PROACTIVE') || feature('KAIROS')` 保护
-
-### 系统提示
-
-激活后追加：
-
-```
-# Proactive Mode
-
-You are in proactive mode. Take initiative -- explore, act, and make progress
-without waiting for instructions.
-
-Start by briefly greeting the user.
-
-You will receive periodic <tick> prompts. These are check-ins. Do whatever
-seems most useful, or call Sleep if there's nothing to do.
-```
-
-### SleepTool 集成
-
-设置中的 `minSleepDurationMs` 和 `maxSleepDurationMs` 控制 Sleep 持续时间范围，节流 proactive tick 频率。没活干就 Sleep 等着。
-
----
-
-## 后台任务管理
-
-### Cron 调度器
-
-`src/utils/cronScheduler.ts`：
-
-- 每 1 秒 tick 一次（`CHECK_INTERVAL_MS = 1000`）
-- 使用 chokidar 监视 `.claude/scheduled_tasks.json`
-- 支持调度器锁（`src/utils/cronTasksLock.ts`），防止多实例重复触发
-- 锁探测间隔 5 秒，持有者崩溃时自动接管
-
-### 任务类型
-
-| 类型 | 说明 |
-|------|------|
-| 一次性（`recurring: false`） | 触发后自动删除，支持错过任务检测 |
-| 循环（`recurring: true`） | 触发后重新调度，默认 7 天过期 |
-| 永久（`permanent: true`） | 不受过期限制（KAIROS 专用） |
-| 会话级（`durable: false`） | 仅内存中，进程退出即消失 |
-
-### Jitter 防雷群机制
-
-`src/utils/cronJitterConfig.ts`：
-
-- 循环任务：基于 taskId 的确定性延迟（interval 的 10%，上限 15 分钟）
-- 一次性任务：在 :00 和 :30 施加最多 90 秒提前量
-- 运维可在事故期间推送配置变更，60 秒内全客户端生效
-
----
-
-## 关键源码文件
-
-| 文件 | 职责 |
-|------|------|
-| `src/bootstrap/state.ts` | KAIROS 全局状态 |
-| `src/assistant/index.ts` | 助手模式入口 |
-| `src/assistant/sessionHistory.ts` | 远程会话历史 API |

-
-## Project Overview
-
-This is a **reverse-engineered / decompiled** version of Anthropic's official Codex CLI tool. The goal is to restore core functionality while trimming secondary capabilities. Many modules are stubbed or feature-flagged off. TypeScript strict mode is enforced — **`bunx tsc --noEmit` must pass with zero errors**.
-
-## Git Commit Message Convention
-
-使用 **Conventional Commits** 规范：
-
-```
-<type>: <描述>
-```
-
-常见 type：`feat`、`fix`、`docs`、`chore`、`refactor`
-
-示例：
-- `feat: 添加模型 1M 上下文切换`
-- `fix: 修复初次登陆的校验问题`
-- `chore: remove prefetchOfficialMcpUrls call on startup`

-
-## Architecture
-
-### Runtime & Build
-
-- **Runtime**: Bun (not Node.js). All imports, builds, and execution use Bun APIs.
-- **Build**: `build.ts` 执行 `Bun.build()` with `splitting: true`，入口 `src/entrypoints/cli.tsx`，输出 `dist/cli.js` + chunk files。Build 默认启用 19 个 feature（见下方 Feature Flag 段）。构建后自动替换 `import.meta.require` 为 Node.js 兼容版本（产物 bun/node 都可运行）。
-- **Dev mode**: `scripts/dev.ts` 通过 Bun `-d` flag 注入 `MACRO.*` defines，运行 `src/entrypoints/cli.tsx`。默认启用全部 feature。
-- **Module system**: ESM (`"type": "module"`), TSX with `react-jsx` transform.
-- **Monorepo**: Bun workspaces — 14 个 internal packages in `packages/` resolved via `workspace:*`。
-- **Lint/Format**: Biome (`biome.json`)。`bun run lint` / `bun run lint:fix` / `bun run format`。
-- **Defines**: 集中管理在 `scripts/defines.ts`。当前版本 `2.1.888`。
-- **CI**: GitHub Actions — `ci.yml`（构建+测试）、`release-rcs.yml`（RCS 发布）、`update-contributors.yml`（自动更新贡献者）。
-
-### Entry & Bootstrap
-
-1. **`src/entrypoints/cli.tsx`** (323 行) — True entrypoint。`main()` 函数按优先级处理多条快速路径：
-   - `--version` / `-v` — 零模块加载
-   - `--dump-system-prompt` — feature-gated (DUMP_SYSTEM_PROMPT)
-   - `--Codex-in-chrome-mcp` / `--chrome-native-host`
-   - `--computer-use-mcp` — 独立 MCP server 模式
-   - `--daemon-worker=<kind>` — feature-gated (DAEMON)
-   - `remote-control` / `rc` / `remote` / `sync` / `bridge` — feature-gated (BRIDGE_MODE)
-   - `daemon` [subcommand] — feature-gated (DAEMON)
-   - `ps` / `logs` / `attach` / `kill` / `--bg` — feature-gated (BG_SESSIONS)
-   - `new` / `list` / `reply` — Template job commands
-   - `environment-runner` / `self-hosted-runner` — BYOC runner
-   - `--tmux` + `--worktree` 组合
-   - 默认路径：加载 `main.tsx` 启动完整 CLI
-2. **`src/main.tsx`** (~6970 行) — Commander.js CLI definition。注册大量 subcommands：`mcp` (serve/add/remove/list...)、`server`、`ssh`、`open`、`auth`、`plugin`、`agents`、`auto-mode`、`doctor`、`update` 等。主 `.action()` 处理器负责权限、MCP、会话恢复、REPL/Headless 模式分发。
-3. **`src/entrypoints/init.ts`** — One-time initialization (telemetry, config, trust dialog)。
-
-### Core Loop
-
-- **`src/query.ts`** — The main API query function. Sends messages to Codex API, handles streaming responses, processes tool calls, and manages the conversation turn loop.
-- **`src/QueryEngine.ts`** — Higher-level orchestrator wrapping `query()`. Manages conversation state, compaction, file history snapshots, attribution, and turn-level bookkeeping. Used by the REPL screen.
-- **`src/screens/REPL.tsx`** — The interactive REPL screen (React/Ink component). Handles user input, message display, tool permission prompts, and keyboard shortcuts.
-
-### API Layer
-
-- **`src/services/api/Codex.ts`** — Core API client. Builds request params (system prompt, messages, tools, betas), calls the Anthropic SDK streaming endpoint, and processes `BetaRawMessageStreamEvent` events.
-- **7 providers**: `firstParty` (Anthropic direct), `bedrock` (AWS), `vertex` (Google Cloud), `foundry`, `openai`, `gemini`, `grok` (xAI)。
-- Provider selection in `src/utils/model/providers.ts`。优先级：modelType 参数 > 环境变量 > 默认 firstParty。
-
-### Tool System
-
-- **`src/Tool.ts`** — Tool interface definition (`Tool` type) and utilities (`findToolByName`, `toolMatchesName`).
-- **`src/tools.ts`** (387 行) — Tool registry. Assembles the tool list; some tools are conditionally loaded via `feature()` flags or `process.env.USER_TYPE`.
-- **`src/tools/<ToolName>/`** — 55 个 tool 目录。主要分类：
-  - **文件操作**: FileEditTool, FileReadTool, FileWriteTool, GlobTool, GrepTool
-  - **Shell/执行**: BashTool, PowerShellTool, REPLTool
-  - **Agent 系统**: AgentTool, TaskCreateTool, TaskUpdateTool, TaskListTool, TaskGetTool
-  - **规划**: EnterPlanModeTool, ExitPlanModeV2Tool, VerifyPlanExecutionTool
-  - **Web/MCP**: WebFetchTool, WebSearchTool, MCPTool, McpAuthTool
-  - **调度**: CronCreateTool, CronDeleteTool, CronListTool
-  - **其他**: LSPTool, ConfigTool, SkillTool, EnterWorktreeTool, ExitWorktreeTool 等
-- **`src/tools/shared/`** — Tool 共享工具函数。
-
-### UI Layer (Ink)
-
-- **`src/ink.ts`** — Ink render wrapper with ThemeProvider injection.
-- **`packages/@ant/ink/`** — Custom Ink framework（forked/internal），包含 components、core、hooks、keybindings、theme、utils。注意：不是 `src/ink/`。
-- **`src/components/`** — 149 个组件目录/文件，渲染于终端 Ink 环境中。关键组件：
-  - `App.tsx` — Root provider (AppState, Stats, FpsMetrics)
-  - `Messages.tsx` / `MessageRow.tsx` — Conversation message rendering
-  - `PromptInput/` — User input handling
-  - `permissions/` — Tool permission approval UI
-  - `design-system/` — 复用 UI 组件（Dialog, FuzzyPicker, ProgressBar, ThemeProvider 等）
-- Components use React Compiler runtime (`react/compiler-runtime`) — decompiled output has `_c()` memoization calls throughout.
-
-### State Management
-
-- **`src/state/AppState.tsx`** — Central app state type and context provider. Contains messages, tools, permissions, MCP connections, etc.
-- **`src/state/AppStateStore.ts`** — Default state and store factory.
-- **`src/state/store.ts`** — Zustand-style store for AppState (`createStore`).
-- **`src/state/selectors.ts`** — State selectors.
-- **`src/bootstrap/state.ts`** — Module-level singletons for session-global state (session ID, CWD, project root, token counts, model overrides, client type, permission mode).
-

-### Bridge / Remote Control
-
-- **`src/bridge/`** (~37 files) — Remote Control / Bridge 模式。feature-gated by `BRIDGE_MODE`。包含 bridge API、会话管理、JWT 认证、消息传输、权限回调等。Entry: `bridgeMain.ts`。
-- **`packages/remote-control-server/`** — 自托管 RCS，支持 Docker 部署，含 Web UI 控制面板。通过 `bun run rcs` 启动。
-- CLI 快速路径: `Codex remote-control` / `Codex rc` / `Codex bridge`。
-- 详见 `docs/features/remote-control-self-hosting.md`。
-
-### Daemon Mode
-
-- **`src/daemon/`** — Daemon 模式（长驻 supervisor）。feature-gated by `DAEMON`。包含 `main.ts`（entry）和 `workerRegistry.ts`（worker 管理）。
-
-### Context & System Prompt
-
-- **`src/context.ts`** — Builds system/user context for the API call (git status, date, AGENTS.md contents, memory files).
-- **`src/utils/claudemd.ts`** — Discovers and loads AGENTS.md files from project hierarchy.
-
-### Feature Flag System
-
-Feature flags control which functionality is enabled at runtime. 代码中统一通过 `import { feature } from 'bun:bundle'` 导入，调用 `feature('FLAG_NAME')` 返回 `boolean`。
-
-**启用方式**: 环境变量 `FEATURE_<FLAG_NAME>=1`。例如 `FEATURE_BUDDY=1 bun run dev`。
-
-**Build 默认 features**（19 个，见 `build.ts`）:
-- 基础: `BUDDY`, `TRANSCRIPT_CLASSIFIER`, `BRIDGE_MODE`, `AGENT_TRIGGERS_REMOTE`, `CHICAGO_MCP`, `VOICE_MODE`
-- 统计/缓存: `SHOT_STATS`, `PROMPT_CACHE_BREAK_DETECTION`, `TOKEN_BUDGET`
-- P0 本地: `AGENT_TRIGGERS`, `ULTRATHINK`, `BUILTIN_EXPLORE_PLAN_AGENTS`, `LODESTONE`
-- P1 API 依赖: `EXTRACT_MEMORIES`, `VERIFICATION_AGENT`, `KAIROS_BRIEF`, `AWAY_SUMMARY`, `ULTRAPLAN`
-- P2: `DAEMON`
-
-**Dev mode 默认**: 全部启用（见 `scripts/dev.ts`）。
-
-**类型声明**: `src/types/internal-modules.d.ts` 中声明了 `bun:bundle` 模块的 `feature` 函数签名。
-
-**新增功能的正确做法**: 保留 `import { feature } from 'bun:bundle'` + `feature('FLAG_NAME')` 的标准模式，在运行时通过环境变量或配置控制，不要绕过 feature flag 直接 import。
-
-### Multi-API 兼容层
-
-所有兼容层均采用流适配器模式：将第三方 API 格式转为 Anthropic 内部格式，下游代码完全不改。
-
-#### OpenAI 兼容层
-
-通过 `CLAUDE_CODE_USE_OPENAI=1` 启用，支持 Ollama/DeepSeek/vLLM 等任意 OpenAI Chat Completions 协议端点。含 DeepSeek thinking mode 支持。
-
-- **`src/services/api/openai/`** — client、消息/工具转换、流适配、模型映射
-- 关键环境变量：`CLAUDE_CODE_USE_OPENAI`、`OPENAI_API_KEY`、`OPENAI_BASE_URL`、`OPENAI_MODEL`
-
-#### Gemini 兼容层
-
-通过 `CLAUDE_CODE_USE_GEMINI=1` 启用。独立环境变量体系。
-
-- **`src/services/api/gemini/`** — client、模型映射、类型定义
-- 关键环境变量：`GEMINI_API_KEY`（必填）、`GEMINI_MODEL`（直接指定）、`GEMINI_DEFAULT_SONNET_MODEL`/`GEMINI_DEFAULT_OPUS_MODEL`（按能力映射）
-- 模型映射优先级：`GEMINI_MODEL` > `GEMINI_DEFAULT_*_MODEL` > `ANTHROPIC_DEFAULT_*_MODEL`(已废弃) > 原样返回
-
-#### Grok 兼容层
-
-通过 `CLAUDE_CODE_USE_GROK=1` 启用。自定义模型映射支持 xAI Grok API。
-
-- **`src/services/api/grok/`** — client、模型映射
-
-详见各兼容层的 docs 文档。
-
-### Stubbed/Deleted Modules
-
-| Module | Status |
-|--------|--------|
-| Computer Use (`@ant/*`) | Restored — macOS + Windows + Linux（后端完整度不一） |
-| `*-napi` packages | `audio-capture-napi`、`image-processor-napi` 已恢复；`color-diff-napi` 完整；`modifiers-napi`、`url-handler-napi` 仍为 stub |
-| Voice Mode | Restored — Push-to-Talk 语音输入（需 Anthropic OAuth） |
-| OpenAI/Gemini/Grok 兼容层 | Restored |
-| Remote Control Server | Restored — 自托管 RCS + Web UI |
-| Analytics / GrowthBook / Sentry | Empty implementations |
-| Magic Docs / LSP Server | Removed |
-| Plugins / Marketplace | Removed |
-| MCP OAuth | Simplified |
-
-### Key Type Files
-
-- **`src/types/global.d.ts`** — Declares `MACRO`, `BUILD_TARGET`, `BUILD_ENV` and internal Anthropic-only identifiers.
-- **`src/types/internal-modules.d.ts`** — Type declarations for `bun:bundle`, `bun:ffi`, `@anthropic-ai/mcpb`.
-- **`src/types/message.ts`** — Message type hierarchy (UserMessage, AssistantMessage, SystemMessage, etc.).
-- **`src/types/permissions.ts`** — Permission mode and result types.
-
-## Testing
-
-- **框架**: `bun:test`（内置断言 + mock）
-- **当前状态**: 2472 tests / 138 files / 0 fail
-- **单元测试**: 就近放置于 `src/**/__tests__/`，文件名 `<module>.test.ts`
-- **集成测试**: `tests/integration/` — 4 个文件（cli-arguments, context-build, message-pipeline, tool-chain）
-- **共享 mock/fixture**: `tests/mocks/`（api-responses, file-system, fixtures/）
-- **命名**: `describe("functionName")` + `test("behavior description")`，英文
-- **Mock 模式**: 对重依赖模块使用 `mock.module()` + `await import()` 解锁（必须内联在测试文件中，不能从共享 helper 导入）
-- **包测试**: `packages/` 下各包也有独立测试（如 `color-diff-napi` 11 tests）
-
-### 类型检查
-
-项目使用 TypeScript strict 模式，**tsc 必须零错误**。每次修改后运行：
-
-```bash
-bunx tsc --noEmit
-```
-
-**类型规范**：
-- 生产代码禁止 `as any`；测试文件中 mock 数据可用 `as any`
-- 类型不匹配优先用 `as unknown as SpecificType` 双重断言，或补充 interface
-- 未知结构对象用 `Record<string, unknown>` 替代 `any`
-- 联合类型用类型守卫（type guard）收窄，不要强转
-- `msg.request` 属性访问：`const req = msg.request as Record<string, unknown>`
-- Ink `color` prop：用 `as keyof Theme` 而非 `as any`
-
-## Working with This Codebase
-
-- **tsc must pass** — `bunx tsc --noEmit` 必须零错误，任何修改都不能引入新的类型错误。
-- **Feature flags** — 默认全部关闭（`feature()` 返回 `false`）。Dev/build 各有自己的默认启用列表。不要在 `cli.tsx` 中重定义 `feature` 函数。
-- **React Compiler output** — Components have decompiled memoization boilerplate (`const $ = _c(N)`). This is normal.
-- **`bun:bundle` import** — `import { feature } from 'bun:bundle'` 是 Bun 内置模块，由运行时/构建器解析。不要用自定义函数替代它。**`feature()` 只能直接用在 `if` 语句或三元表达式的条件位置**（Bun 编译器限制），不能赋值给变量、不能放在箭头函数体里、不能作为 `&&` 链的一部分。正确：`if (feature('X')) {}` 或 `feature('X') ? a : b`。
-- **`src/` path alias** — tsconfig maps `src/*` to `./src/*`. Imports like `import { ... } from 'src/utils/...'` are valid.
-- **MACRO defines** — 集中管理在 `scripts/defines.ts`。Dev mode 通过 `bun -d` 注入，build 通过 `Bun.build({ define })` 注入。修改版本号等常量只改这个文件。
-- **构建产物兼容 Node.js** — `build.ts` 会自动后处理 `import.meta.require`，产物可直接用 `node dist/cli.js` 运行。
-- **Biome 配置** — 大量 lint 规则被关闭（decompiled 代码不适合严格 lint）。`.tsx` 文件用 120 行宽 + 强制分号；其他文件 80 行宽 + 按需分号。
-- **Ink 框架在 `packages/@ant/ink/`** — 不是 `src/ink/`（该目录不存在）。Ink 相关的组件、hooks、keybindings 都在 packages 中。
-- **Provider 优先级** — `modelType` 参数 > 环境变量 > 默认 `firstParty`。新增 provider 需在 `src/utils/model/providers.ts` 注册。

+1. **Considered over clever** — 每个设计选择都应感觉有意为之，而非追逐潮流
+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

+### 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

+# 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    ┌──────────────┐
+│  浏览器/客户端     │ ◄──────────────►│  acp-link        │ ◄────────────────►│  ACP Agent   │

+```
+
+## 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: {} })
+
+// 创建会话
+const { sessionId } = await client.newSession({
+  cwd: '/path/to/project',
+})
+
+// 发送 prompt
+const response = await client.prompt({
+  sessionId,
+  prompt: [{ type: 'text', text: 'Hello, explain this project' }],
+})
+
+// 监听 session 更新
+client.on('sessionUpdate', (update) => {
+  console.log('Update:', update)
+})
+```
+

+
+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
 
 Web UI 使用 UUID 认证（无需用户账户），适合受信任网络环境。

+# acp-link
+
+ACP proxy server that bridges WebSocket clients to ACP (Agent Client Protocol) agents.
+
+> Source code adapted from [chrome-acp](https://github.com/Areo-Joe/chrome-acp).
+
+## Installation
+
+### From source
+
+```bash
+# From monorepo root
+bun install
+```
+
+## Usage
+
+```bash
+# Via global install
+acp-link /path/to/agent
+
+# Via source
+bun src/cli/bin.ts /path/to/agent
+```
+
+### Examples
+
+```bash
+# Basic usage
+acp-link /path/to/agent
+
+# With custom port and host
+acp-link --port 9000 --host 0.0.0.0 /path/to/agent
+
+# With debug logging
+acp-link --debug /path/to/agent
+
+# Enable HTTPS with self-signed certificate
+acp-link --https /path/to/agent
+
+# Disable authentication (dangerous)
+acp-link --no-auth /path/to/agent
+
+# Pass arguments to the agent (use -- to separate)
+acp-link /path/to/agent -- --verbose --model gpt-4
+```
+
+## CLI Reference
+
+```
+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
+```
+
+## 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).
