 ## Project Overview
 
-LangBot is a open-source LLM native instant messaging bot development platform, aiming to provide an out-of-the-box IM robot development experience, with Agent, RAG, MCP and other LLM application functions, supporting global instant messaging platforms, and providing rich API interfaces, supporting custom development.
+LangBot is an open-source, LLM-native instant-messaging bot development platform. It aims to provide an out-of-the-box IM bot development experience with Agent, RAG, MCP and other LLM application capabilities, supporting mainstream global IM platforms and exposing rich APIs for custom development.
 
-LangBot has a comprehensive frontend, all operations can be performed through the frontend. The project splited into these major parts:
+LangBot has a comprehensive web frontend — almost every operation can be performed through it.
 
-- `./src/langbot`: The main python package of the project, below are the main modules in this package:
+- **Python**: `>=3.11,<4.0`, dependencies managed by `uv`. Package version is in `pyproject.toml`.
-    - `./pkg`: The core python package of the project backend.
+- **Frontend**: `web/` is a **Vite + React Router 7 + shadcn/ui + Tailwind CSS** SPA, managed by `pnpm`. (Note: this is NOT Next.js — the `dev` script is `vite`.)
-        - `./pkg/platform`: The platform module of the project, containing the logic of message platform adapters, bot managers, message session managers, etc.
+- **Backend framework**: Quart (the async flavour of Flask). The HTTP API and the pre-built web UI are both served by the backend on `http://127.0.0.1:5300`.
-        - `./pkg/provider`: The provider module of the project, containing the logic of LLM providers, tool providers, etc.
-        - `./pkg/pipeline`: The pipeline module of the project, containing the logic of pipelines, stages, query pool, etc.
-        - `./pkg/api`: The api module of the project, containing the http api controllers and services.
-        - `./pkg/plugin`: LangBot bridge for connecting with plugin system.
-    - `./libs`: Some SDKs we previously developed for the project, such as `qq_official_api`, `wecom_api`, etc.
-    - `./templates`: Templates of config files, components, etc.
-    - `./web`: Frontend codebase, built with Next.js + **shadcn** + **Tailwind CSS**.
-    - `./docker`: docker-compose deployment files.

+
+## Development Environment Setup
+
+Full guide lives in the wiki: **["开发配置" / Dev Config](https://docs.langbot.app/zh/develop/dev-config)**. Summary:
+
+### Backend
 
 ```bash
 pip install uv
-uv sync --dev
+uv sync --dev          # uv creates a .venv/ for you; point your editor's interpreter at it
+uv run main.py         # serves API + web UI on http://127.0.0.1:5300
 ```
 
-Start the backend and run the project in development mode.
+On first run the config file is generated at `data/config.yaml`. DB is SQLite by default (zero setup); PostgreSQL is supported. Migrations run automatically on startup.
 
-```bash
+### Frontend
-uv run main.py
-```
 
-Then you can access the project at `http://127.0.0.1:5300`.
+Requires Node.js + [pnpm](https://pnpm.io/installation).
-
-## Frontend Development
-
-We use `pnpm` to manage dependencies.
 
 ```bash
 cd web
-cp .env.example .env
+cp .env.example .env   # Windows: copy .env.example .env
 pnpm install
-pnpm dev
+pnpm dev               # http://127.0.0.1:3000  (npm install / npm run dev also work)
 ```
 
-Then you can access the project at `http://127.0.0.1:3000`.
+`pnpm dev` reads `VITE_API_BASE_URL` from `web/.env` so the dev frontend can reach the backend on port `5300`. In production the frontend is pre-built into static files served by the backend on the same origin.
 
-## Plugin System Architecture
+### Code formatting
 
-LangBot is composed of various internal components such as Large Language Model tools, commands, messaging platform adapters, LLM requesters, and more. To meet extensibility and flexibility requirements, we have implemented a production-grade plugin system.
+The repo runs lint + format checks in CI. Install the pre-commit hooks so the same checks run locally before each commit:
 
-Each plugin runs in an independent process, managed uniformly by the Plugin Runtime. It has two operating modes: `stdio` and `websocket`. When LangBot is started directly by users (not running in a container), it uses `stdio` mode, which is common for personal users or lightweight environments. When LangBot runs in a container, it uses `websocket` mode, designed specifically for production environments.
+```bash
+uv run pre-commit install
+```
 
-Plugin Runtime automatically starts each installed plugin and interacts through stdio. In plugin development scenarios, developers can use the lbp command-line tool to start plugins and connect to the running Runtime via WebSocket for debugging.
+## Plugin System
 
-> Plugin SDK, CLI, Runtime, and entities definitions shared between LangBot and plugins are contained in the [`langbot-plugin-sdk`](https://github.com/langbot-app/langbot-plugin-sdk) repository.
+LangBot's plugin system (Plugin SDK, CLI `lbp`, Plugin Runtime, and the shared entity/API definitions) lives in a **separate repository**: [`langbot-plugin-sdk`](https://github.com/langbot-app/langbot-plugin-sdk). LangBot depends on it via the pinned `langbot-plugin` package in `pyproject.toml`.
 
-## Some Development Tips and Standards
+### Architecture (what to know inside this repo)
 
-- LangBot is a global project, any comments in code should be in English, and user experience should be considered in all aspects.
+- Plugins run as independent processes managed by the **Plugin Runtime**. The Runtime supports two control transports: `stdio` and `websocket`.
-- Thus you should consider the i18n support in all aspects.
+- When LangBot is started directly by a user (not in a container), it spawns and connects to the Runtime over **stdio** (lightweight/personal use).
-- LangBot is widely adopted in both toC and toB scenarios, so you should consider the compatibility and security in all aspects.
+- When LangBot runs in a container, it connects to a standalone Runtime over **WebSocket** (production).
-- If you were asked to make a commit, please follow the commit message format: 
+- The bridge code lives in `src/langbot/pkg/plugin/` (`connector.py`, `handler.py`).
-    - format: <type>(<scope>): <subject>
+- Relevant config (`data/config.yaml`): `plugin.runtime_ws_url` (e.g. `ws://langbot_plugin_runtime:5400/control/ws`). Start LangBot with `--standalone-runtime` to make it connect to an externally-launched Runtime over WebSocket instead of spawning one over stdio.
-    - type: must be a specific type, such as feat (new feature), fix (bug fix), docs (documentation), style (code style), refactor (refactoring), perf (performance optimization), etc.
+
-    - scope: the scope of the commit, such as the package name, the file name, the function name, the class name, the module name, etc.
+### Debugging the Plugin Runtime / CLI / SDK
-    - subject: the subject of the commit, such as the description of the commit, the reason for the commit, the impact of the commit, etc.
+
-- If you changed the definition of database entities, please update the migration file in `src/langbot/pkg/persistence/migrations/` and update the constants.py file in `src/langbot/pkg/utils/constants.py` with the new migration number.
+This is documented in detail in the **SDK repo's `AGENTS.md`** and in the wiki page **["调试插件运行时、CLI、SDK" / Plugin Runtime](https://docs.langbot.app/zh/develop/plugin-runtime)**. The short version:
+
+- Clone `LangBot` and `langbot-plugin-sdk` as siblings under one parent dir so the editor resolves shared entities.
+- Start a standalone Runtime from the SDK repo: `uv run --no-sync lbp rt` (control port `5400`, debug port `5401`).
+- To make LangBot use a locally-modified SDK: from the SDK dir, with LangBot's `.venv` active, run `uv pip install .`, then launch LangBot with `uv run --no-sync main.py --standalone-runtime` (keep `--no-sync` so your local SDK isn't overwritten).
+
+### Debugging the Box (sandbox) runtime
+
+The Box subsystem (`src/langbot/pkg/box/`) is the code sandbox. It picks the first available backend among **Docker / nsjail / E2B**. The standalone Box runtime is launched via the SDK CLI: `lbp box`. Backend selection details, the `lbp box` flags, and the SDK-side architecture are documented in the SDK repo's `AGENTS.md`.
+
+Relevant config (`data/config.yaml`, `box:` section): `box.enabled` (master switch — disabling it also disables the native sandbox tools, skill add/edit, and stdio-mode MCP servers), `box.backend` (`'local'` = Docker/nsjail auto-pick, or `'docker'` / `'nsjail'` / `'e2b'`; also settable via `BOX__BACKEND`), and `box.runtime.endpoint` (external Box runtime base URL, e.g. `ws://127.0.0.1:5410`; empty = local auto-managed runtime). Like the plugin runtime, LangBot can connect to an externally-launched Box runtime by setting that endpoint and starting with `--standalone-box`.
+
+> A common false "No supported sandbox backend (Docker / nsjail / E2B) is available" comes from Docker being installed and running but the current user not being in the `docker` group → `docker info` gets `permission denied` on the socket. Fix: `sudo usermod -aG docker <user>` and restart the backend in a shell that has the new group.
+
+## Development Standards
+
+- LangBot is a global project: **all code comments and docstrings must be in English**, and every user-facing string must support **i18n** (`en_US` + `zh_Hans` at minimum, plus `ja_JP` where the repo already has it).
+- LangBot is adopted in both toC and toB scenarios — always consider compatibility and security.
+- **Commit message format**: `<type>(<scope>): <subject>`
+  - `type`: one of `feat`, `fix`, `docs`, `style`, `refactor`, `perf`, `test`, `chore`, etc.
+  - `scope`: the affected package/module/file/class.
+  - `subject`: concise description of the change.
+
+### Database migrations (Alembic)
+
+LangBot uses [Alembic](https://alembic.sqlalchemy.org/) for migrations, supporting both SQLite and PostgreSQL from a single set of scripts. Migration files live in `src/langbot/pkg/persistence/alembic/versions/`.
+
+If you change ORM model definitions, generate a migration:
+
+```bash
+# Run from the project root (requires data/config.yaml to exist)
+uv run python -m langbot.pkg.persistence.alembic_runner autogenerate "description of your change"
+```
+
+Review and edit the generated script before committing. Migrations execute automatically on startup. `autogenerate` detects schema changes (add/drop columns, tables, type changes) but **data migrations** (e.g. mutating JSON field contents) must be hand-written into the generated script. `env.py` sets `render_as_batch=True`, so SQLite's ALTER TABLE limits are handled automatically — no need to branch per database. More in the wiki ["开发配置"](https://docs.langbot.app/zh/develop/dev-config#数据库迁移).

+```
+
+**核心设计原则**:
+- Box Runtime 作为独立进程运行，通过 Action RPC 与 LangBot 主进程通信，两者复用 SDK 的 IO 层（Handler → Connection → Controller）
+- 一个 session_id 对应一个容器/沙箱实例。同一 session 内可并存多条 mount 与多个 managed process
+- Skill / 默认 exec / MCP Server 共享同一个 session 容器（详见 [box-session-scope.md](./box-session-scope.md)）
+
+---
+
+## 2. LangBot 侧模块
+
+### 2.1 BoxService (`pkg/box/service.py`, 722 行)
+
+应用层门面，协调 Profile、安全校验、配额、连接、Skill 挂载与 Session 模板：
+
+主要公开方法（按定义顺序）：
+
+```
+BoxService
+  ├─ initialize()                              连接 Box Runtime + 默认 workspace 准备
+  ├─ _on_runtime_disconnect(connector)         触发重连
+  ├─ _reconnect_loop(connector)                指数退避重连
+  ├─ available (property)                      连接状态
+  │
+  ├─ resolve_box_session_id(query)             从 pipeline 模板解析 session_id
+  ├─ build_skill_extra_mounts(query)           组装 pipeline-bound skill 的挂载列表
+  │
+  ├─ execute_tool(parameters, query)           Agent 调用 exec 时的入口
+  │    ├─ _apply_profile / build_spec
+  │    ├─ _validate_host_mount
+  │    ├─ _enforce_workspace_quota (phase=pre)
+  │    ├─ client.execute(spec)
+  │    ├─ _enforce_workspace_quota (phase=post)
+  │    └─ _truncate (stdout/stderr)
+  │
+  ├─ execute_spec_payload(spec_payload, ...)   内部入口（其他 loader 调用）
+  ├─ create_session(spec_payload, ...)         显式创建 session
+  ├─ start_managed_process(session_id, ...)    启动 managed process
+  ├─ get_managed_process(session_id, pid)      查询进程状态（pid 默认 'default'）
+  ├─ stop_managed_process(session_id, pid)     单独停止某个 managed process
+  ├─ get_managed_process_websocket_url(...)    返回 WS attach URL
+  │
+  ├─ list_skills() / get_skill(name)           Skill 元数据
+  ├─ create_skill / update_skill / delete_skill  Skill CRUD
+  ├─ scan_skill_directory(path)                扫描目录
+  ├─ list_skill_files / read_skill_file / write_skill_file
+  ├─ preview_skill_zip / install_skill_zip     zip / GitHub 安装
+  │
+  ├─ shutdown() / dispose()                    清理：RPC SHUTDOWN + 进程终止
+  ├─ get_status() / get_sessions() / get_recent_errors()
+  └─ get_system_guidance()                     LLM 系统提示
+```
+
+**Profile 系统**: 4 个内置 Profile（`default` / `offline_readonly` / `network_basic` / `network_extended`），`locked` frozenset 字段不可被 LLM 覆盖。参数合并顺序：Profile defaults → LLM 请求参数 → locked 强制值。
+
+**输出截断**: 默认 4000 字符上限，保留前 60% + 后 40%，中间插入 `[...truncated...]`。
+
+**Skill 挂载合并**: `execute_tool()` 调用时，`build_skill_extra_mounts(query)` 会把当前 pipeline-bound 的所有 skill 的 `package_root` 作为 `extra_mounts` 加入 BoxSpec，挂在 `/workspace/.skills/<name>`。LLM 通过 `activate` 工具显式激活某个 skill 后，工具调用才允许引用这个 skill 的虚拟路径。
+
+### 2.2 BoxRuntimeConnector (`pkg/box/connector.py`, 357 行)
+
+管理与 Box Runtime 的通信连接：
+
+- **本地 stdio**: Unix/macOS 默认路径，fork `python -m langbot_plugin.cli.__init__ box -s --ws-control-port {port}` 子进程（与 plugin runtime 统一走 `lbp` CLI 入口）
+- **本地 subprocess + WS**: Windows 本地（asyncio ProactorEventLoop 不支持 stdio pipe）
+- **远程 WebSocket**: Docker 部署 / `box.runtime.endpoint` 显式配置时，连接 `ws://{host}:{port}/rpc/ws`
+- **同步等待**: `asyncio.Event` + `wait_for(timeout=30s)` 模式确认连接
+- **心跳**: `_heartbeat_loop()` 每 20s 调用 `ping()`，失败仅 DEBUG 日志（断开检测靠 connection close）
+- **重连**: `runtime_disconnect_callback` 由 BoxService 提供，触发 `_reconnect_loop`
+- **INIT 注入**: 连接建立后立即下发当前 `box.*` 配置子树（剔除 `runtime` 私有字段），Runtime 据此初始化 backend
+
+> **历史改进**: 2026-04-16 版本本文档曾列 P0 「Box 无心跳 / 无重连」，已修复（commit `2dfd9d5d`、`c6882cf`、`5029d9c` 等）。
+
+### 2.3 BoxWorkspaceSession 工具 (`pkg/box/workspace.py`, 413 行)
+
+此文件目前提供两类能力：
+
+1. **路径与命令重写工具函数** — `normalize_host_path` / `rewrite_mounted_path` / `unwrap_venv_path` / `rewrite_venv_command` / `infer_workspace_host_path`，被 MCP loader 与 Skill 路径解析共用。
+2. **`BoxWorkspaceSession`** — 围绕 BoxService 的轻量包装，专供 MCP-in-Box 场景使用（管理一个共享 session 的 session_id、构建挂载 payload、stage host 文件到共享 workspace）。
+
+**变化点**: 早期 Skill exec 会为每个 skill 创建独立 BoxWorkspaceSession（独占 session）；当前实现已转为 `extra_mounts` 模式，Skill 不再独占容器，只追加挂载。这部分 wrapping 逻辑已从 native loader 移除。
+
+### 2.4 policy.py (`pkg/box/policy.py`, 98 行) — 仍是死代码
+
+三层安全策略设计（`SandboxPolicy` / `ToolPolicy` / `ElevatedPolicy`），全项目无任何导入或调用。详见 [SaaS 阻塞项 S2](./box-issues.md)。
+
+### 2.5 SkillManager (`pkg/skill/manager.py`, 186 行)
+
+```
+SkillManager
+  ├─ initialize()                  调用 reload_skills()
+  ├─ reload_skills()               先从 Box runtime list_skills()，
+  │                                 不可用则回落 data/skills/ 扫描
+  ├─ refresh_skill_from_disk()     单 skill 重新加载
+  ├─ get_skill_by_name(name)
+  └─ get_managed_skills_root()     返回 Box 视角的 skills_root 路径
+```
+
+skill 元数据通过 `parse_frontmatter` 解析 `SKILL.md` 头部（`name` / `description` / `instructions`），不再做整体扫描的代价（典型 < 50 个）。
+
+### 2.6 Skill activation (`pkg/skill/activation.py`, 33 行) + Skill loader 辅助
+
+历史上 skill 通过 LLM 在文本中输出 `[ACTIVATE_SKILL:name]` 标记激活；当前已改为 **Tool Call 机制**：
+
+- `SkillToolLoader` (`pkg/provider/tools/loaders/skill.py`, 157 行) 暴露 `activate` 工具，参数为 skill 名
+- 工具实现调用 `register_activated_skill(query, skill_data)`，将激活态写入 `query.variables['_activated_skills']`
+- 这种 KV-cache-friendly 模式对齐 Claude Code 设计；详见 [box-session-scope.md §4.3](./box-session-scope.md) 的 Tool Call 描述
+
+`activation.py` 现仅保留对外辅助函数（pipeline 层调用 loader 的 `register_activated_skill`）。
+
+---
+
+## 3. SDK 侧模块
+
+### 3.1 BoxRuntime (`box/runtime.py`, 599 行)
+
+核心编排器，管理 session 生命周期与 backend 调度：
+
+```
+Session 生命周期:
+
+  Client EXEC / CREATE_SESSION
+       │
+       ▼
+  _get_or_create_session(spec)
+    ├─ _reap_expired_sessions_locked()   清理 TTL 过期 session
+    ├─ 已存在? → _assert_session_compatible() → 复用
+    ├─ Backend session 失踪? → 重建 (commit c6882cf)
+    └─ 新建? → backend.start_session(spec) → 创建容器
+       │       └─ 应用 spec.extra_mounts （多挂载）
+       ▼
+  execute(spec)
+    ├─ 获取 session lock (每 session 独立)
+    ├─ backend.exec(session, spec)       在容器中执行命令
+    ├─ 更新 last_used_at
+    └─ 超时? → 销毁 session
+       │
+       ▼
+  Session 保持存活直到:
+    ├─ TTL 过期 (默认 300s，下次操作时清理)
+    ├─ 执行超时 (自动销毁)
+    ├─ 客户端 DELETE_SESSION
+    └─ SHUTDOWN
+```
+
+**关键设计**:
+- 每 session 有独立 `asyncio.Lock`，同一 session 内的命令串行执行
+- 每 session 维护 `managed_processes: dict[process_id, _ManagedProcess]`，支持多个长驻进程并存（MCP / 自定义）
+- 全局 `_lock` 保护 `_sessions` dict 的读写
+- 兼容性检查：比较核心 spec 字段，`image` 字段对不支持自定义镜像的 backend（nsjail/E2B）会跳过
+
+**Backend 选择 (`_select_backend`)**: 优先级
+1. 显式 `box.backend` 配置（`docker` / `nsjail` / `e2b`）
+2. `local` (默认) → Docker / Podman / nsjail CLI 顺序探测
+3. `get_status` 调用时若当前 backend 不可用，会尝试重新选择 (commit `e5617c7`)
+
+### 3.2 Backend 系统
+
+#### CLISandboxBackend (`box/backend.py`, 411 行)
+
+Docker / Podman 公共基类：
+
+```
+start_session(spec):
+  1. validate_sandbox_security(spec)
+  2. docker/podman run -d --rm --name <name>
+     --network none (可选)
+     --cpus/--memory/--pids-limit
+     --read-only + --tmpfs /tmp
+     -v <host>:<mount>:<mode>          主挂载
+     -v <extra.host>:<extra.mount>:..  额外挂载 (extra_mounts)
+     <image> sh -lc 'while true; do sleep 3600; done'
+  3. 返回 BoxSessionInfo
+
+exec(session, spec):
+  docker/podman exec -e KEY=VAL <container>
+    sh -lc 'mkdir -p <workdir> && cd <workdir> && <cmd>'
+
+start_managed_process(session, spec):
+  docker/podman exec -i <container>
+    sh -lc 'mkdir -p <cwd> && cd <cwd> && exec <command> <args>'
+  返回 asyncio.subprocess.Process (stdin/stdout PIPE)
+```
+
+容器以 idle 进程启动，实际命令通过 `docker exec` 执行。`--rm` 确保容器退出时自动清理。
+
+**Windows 支持**: backend 内对 Windows 路径处理与 subprocess 调用做了适配（commit `120817a`）。
+
+**孤儿清理**: 启动时枚举 `langbot.box=true` 标签的容器，instance_id 不匹配的强制删除。
+
+#### NsjailBackend (`box/nsjail_backend.py`, 552 行)
+
+轻量级 Linux 沙箱（无容器引擎依赖）：
+
+- 使用 namespace 隔离（user/mount/pid/ipc/uts/cgroup/net）
+- 挂载宿主 `/usr`/`/lib`/`/bin`/`/sbin` 只读 + 选定 `/etc` 条目
+- 每 session 创建独立目录（workspace/tmp/home）
+- 资源限制: cgroup v2 优先，fallback 到 rlimit
+- **CLI 兼容**: 通过 `shutil.which(self._nsjail_bin)` 检测系统安装版 nsjail；不存在时再尝试容器内 nsjail（commit `686fcc0`、`feed530`）
+- **无自定义镜像**: 使用宿主 OS，`image` 字段固定为 `'host'`，兼容性检查跳过 image
+
+#### E2BBackend (`box/e2b_backend.py`, 429 行)
+
+云沙箱后端（commit `75b547f` 引入）：
+
+- 通过 `e2b` SDK 与 E2B 平台通信
+- 配置：`box.e2b.api_key` / `api_url` / `template`
+- 支持 `extra_mounts`（commit `0fea9b1` 同步上传文件）
+- 无本地容器引擎依赖，适合无 Docker 的部署或 SaaS 多租户场景
+- 不支持自定义 image 字段，由 template 控制
+
+### 3.3 Server (`box/server.py`, 508 行)
+
+单端口 aiohttp 服务（默认 5410），通过路径区分（commit `8c71ec5` 合并端口）：
+
+1. **Action RPC** (`/rpc/ws`): `BoxServerHandler` 处理所有 action，包括 `INIT` 配置注入、skill store 操作等
+2. **WS Relay** (`/v1/sessions/{id}/managed-process/ws` 与 `/v1/sessions/{id}/managed-process/{pid}/ws`): 双向桥接 WebSocket ↔ 指定 managed process stdin/stdout
+
+stdio 模式同样会在 5410 启动 aiohttp，专门承担 managed process attach；Action RPC 走 stdin/stdout。
+
+### 3.4 Client (`box/client.py`, 377 行)
+
+`ActionRPCBoxClient` 封装 `Handler.call_action()` 调用：
+
+- 25+ 方法对应 25+ 个 RPC action（exec / session / managed-process / skill / status / shutdown）
+- 错误还原: `_translate_action_error()` 通过字符串前缀匹配还原 SDK 侧异常类型
+- `execute()` timeout = 300s，其他默认 15s
+- `BoxRuntimeClient` 是 ABC，供后续可能的非 RPC 实现复用
+
+包级别 `__init__.py` 显式导出：`BoxRuntimeClient`、`ActionRPCBoxClient`（commit `df9c722`）。
+
+### 3.5 Actions (`box/actions.py`, 34 行)
+
+`LangBotToBoxAction` 枚举共定义 **25 个** action：
+
+| 类别 | Actions |
+|------|---------|
+| 控制 | `INIT`、`HEALTH`、`STATUS`、`GET_BACKEND_INFO`、`SHUTDOWN` |
+| 执行 | `EXEC` |
+| Session | `CREATE_SESSION` / `GET_SESSION` / `GET_SESSIONS` / `DELETE_SESSION` |
+| Managed Process | `START_MANAGED_PROCESS` / `GET_MANAGED_PROCESS` / `STOP_MANAGED_PROCESS` |
+| Skill | `LIST_SKILLS` / `GET_SKILL` / `CREATE_SKILL` / `UPDATE_SKILL` / `DELETE_SKILL` / `SCAN_SKILL_DIRECTORY` / `LIST_SKILL_FILES` / `READ_SKILL_FILE` / `WRITE_SKILL_FILE` / `PREVIEW_SKILL_ZIP` / `INSTALL_SKILL_ZIP` |
+
+### 3.6 Models (`box/models.py`, 331 行)
+
+核心数据模型：
+
+| 模型 | 用途 |
+|------|------|
+| `BoxNetworkMode` | `OFF` / `ON` |
+| `BoxExecutionStatus` | `COMPLETED` / `TIMED_OUT` |
+| `BoxHostMountMode` | `NONE` / `READ_ONLY` / `READ_WRITE` |
+| `BoxManagedProcessStatus` | `RUNNING` / `EXITED` |
+| `BoxMountSpec` | 单条挂载（host_path/mount_path/mode）— **新增** |
+| `BoxSpec` | 执行请求；新增 `extra_mounts: list[BoxMountSpec]`、`persistent`、`workspace_quota_mb` |
+| `BoxProfile` | 4 个内置 Profile + `locked` frozenset |
+| `BoxSessionInfo` | Session 状态（含 backend_name/created_at/last_used_at） |
+| `BoxManagedProcessSpec` | 长驻进程参数（process_id/command/args/env/cwd） |
+| `BoxManagedProcessInfo` | 进程状态（status/exit_code/stderr_preview/attached） |
+| `BoxExecutionResult` | 执行结果（status/exit_code/stdout/stderr/duration_ms） |
+
+`BoxSpec` 校验器: `workdir` 默认继承 `mount_path`；`host_path` 支持 POSIX 和 Windows 路径；设置 `host_path` 时 `workdir` 必须在 `mount_path` 下。
+
+### 3.7 BoxSkillStore (`box/skill_store.py`, 647 行)
+
+新增模块（commit `4ab3502`），把 skill 持久化收归 Box runtime：
+
+```
+BoxSkillStore
+  ├─ list_skills() / get_skill(name)
+  ├─ create_skill(data) / update_skill(name, data) / delete_skill(name)
+  ├─ scan_skill_directory(path)            扫描目录返回候选 skill 包列表
+  ├─ list_skill_files(name, path)          浏览 skill 内文件树
+  ├─ read_skill_file(name, path) / write_skill_file(name, path, content)
+  ├─ preview_skill_zip(zip_bytes, ...)     不落盘预览 zip 内容
+  └─ install_skill_zip(zip_bytes, ...)     解压、校验、复制到 skills_root
+     └─ 支持 source_subdir / target_suffix（commit 1aa043f）
+```
+
+GitHub 安装路径：HTTP 层（`api/http/service/skill.py`）先 `git clone` 拉取，再走 `install_skill_zip` 或 directory 路径。Skill 文件存放于 `box.local.skills_root`（默认 `skills`，相对 `host_root`），容器内对应 `/workspace/.skills/`。
+
+### 3.8 Security (`box/security.py`, 52 行)
+
+`validate_sandbox_security()`: 黑名单校验 host_path，阻止挂载 `/etc`/`/proc`/`/sys`/`/dev`/`/root`/`/boot` 及 Docker/Podman socket。
+
+**已知缺陷**: 根路径 `/` 未拦截，用户 home 目录未拦截，是 denylist 而非 allowlist 策略。详见 [SaaS 阻塞项 S5](./box-issues.md)。
+
+### 3.9 Errors (`box/errors.py`, 33 行)
+
+| 异常类型 | 含义 |
+|----------|------|
+| `BoxError` | 基类 |
+| `BoxValidationError` | spec/参数校验失败 |
+| `BoxBackendUnavailableError` | 无可用 backend |
+| `BoxRuntimeUnavailableError` | Runtime 服务不可用 |
+| `BoxSessionConflictError` | session 已存在但 spec 不兼容 |
+| `BoxSessionNotFoundError` | session 不存在 |
+| `BoxManagedProcessConflictError` | session 已有同名 process |
+| `BoxManagedProcessNotFoundError` | process 不存在 |
+
+---
+
+## 4. 工具系统集成
+
+### 4.1 ToolManager 编排 (`toolmgr.py`)
+
+```
+ToolManager.initialize()
+  ├─ NativeToolLoader      (exec / read / write / edit / glob / grep)
+  ├─ PluginToolLoader      (插件工具)
+  ├─ MCPLoader             (MCP Server 工具)
+  ├─ SkillToolLoader       (activate 工具 — Tool Call 激活)
+  └─ SkillAuthoringToolLoader  (Skill CRUD)
+
+工具调用优先级: native → plugin → mcp → skill → skill_authoring
+```
+
+### 4.2 Native Tools (`native.py`, 846 行)
+
+| 工具 | 是否在 Box 中执行 | 是否访问宿主文件系统 |
+|------|:---:|:---:|
+| `exec`  | 是 | 否 |
+| `read`  | **否** | **是** — 直接 `open()` 宿主文件 |
+| `write` | **否** | **是** — 直接 `open()` 宿主文件 |
+| `edit`  | **否** | **是** — 直接 `open()` 宿主文件 |
+| `glob`  | **否** | **是** — 直接遍历宿主目录 |
+| `grep`  | **否** | **是** — 直接读宿主文件 |
+
+**沙箱边界不对称**: 这是刻意的设计权衡 — `read`/`write`/`edit`/`glob`/`grep` 绕过沙箱以获得性能（避免容器 I/O 开销与跨进程拷贝），但意味着 LLM 可以直接读写 `allowed_mount_roots` 下任何文件。Skill 路径经 `_resolve_host_path()` 重写，禁止穿越 `package_root`。
+
+**exec 的 Skill 分支**: 命令中引用 `/workspace/.skills/<name>` 的 skill 时：
+1. 验证 skill 已激活
+2. 单次 exec 只能引用一个 skill 包
+3. 若 skill 是 Python 项目（有 `requirements.txt` 或 `pyproject.toml`），命令会被 venv bootstrap 包裹（在 skill 挂载点内创建 `.venv`）
+4. 调用 `box_service.execute_tool()` → 走默认 session_id 与已组装好的 `extra_mounts`，**不再为每 skill 起独立 session**
+
+### 4.3 MCP-in-Box (`mcp_stdio.py`, 354 行)
+
+`BoxStdioSessionRuntime` 让 MCP stdio 服务器在 Box 容器中运行，**共享 session、多 process**模式（commit `529088e`）：
+
+```
+initialize()
+  1. 复用/创建共享 session (session_id = _build_box_session_id())
+     - persistent=True，长期保持
+  2. workspace.execute_raw(install_cmd) 安装依赖 (可选)
+  3. 将每个 MCP server 文件 stage 到 /workspace/.mcp/<process_id>/
+  4. workspace.start_managed_process(process_id=<server>)
+  5. websocket_client(ws_url) 通过 WS relay 连接
+  6. ClientSession.initialize() MCP 协议握手
+```
+
+配置 (`MCPServerBoxConfig`): `network='on'` (MCP 服务器通常需要网络)，`host_path_mode='ro'` (默认只读)，`startup_timeout_sec=120` (留时间给 pip install)。
+
+每条 MCP server 是同一 session 中的一个 managed process，独立的 `process_id`、独立 attach URL，互不阻塞。
+
+---
+
+## 5. 启动与生命周期
+
+### 5.1 启动顺序 (`build_app.py`)
+
+```
+BuildAppStage.run(ap)
+  ├─ ... (persistence, models, sessions) ...
+  │
+  ├─ BoxService(ap)
+  ├─ box_service.initialize()
+  │    └─ connector.initialize()
+  │         ├─ [stdio] fork box subprocess
+  │         ├─ [subprocess+WS] Windows 本地
+  │         └─ [remote WS] connect URL
+  │    └─ 启动心跳 _heartbeat_task
+  ├─ ap.box_service = box_service
+  │
+  ├─ ToolManager(ap)
+  ├─ tool_mgr.initialize()
+  │    ├─ NativeToolLoader   (检查 box_service.available)
+  │    ├─ PluginToolLoader
+  │    ├─ MCPLoader          (Box 可用时，stdio MCP 走沙箱)
+  │    └─ SkillAuthoringToolLoader
+  ├─ ap.tool_mgr = tool_mgr
+  │
+  ├─ ... (platform, pipeline) ...
+  ├─ SkillManager.initialize()    (从 Box runtime 加载 skill 列表)
+  └─ ... (RAG, HTTP, plugins) ...
+```
+
+BoxService 在 ToolManager **之前**初始化。ToolManager 创建 loader 时检查 `box_service.available`。
+
+### 5.2 初始化失败处理
+
+```python
+try:
+    await self._runtime_connector.initialize()
+    self._available = True
+except Exception as e:
+    self._available = False
+    logger.warning(f"Box runtime unavailable: {e}")
+```
+
+**静默降级**: Box 初始化失败不会阻止应用启动，仅导致 6 个 native tool、所有 Skill 工具和 MCP-in-Box 工具不暴露给 LLM。与 Plugin 的行为不同（Plugin 失败会抛异常）。
+
+### 5.3 销毁流程
+
+```
+app.dispose()
+  └─ box_service.dispose()
+       ├─ connector.dispose()
+       │    ├─ cancel _heartbeat_task
+       │    ├─ cancel _handler_task / _ctrl_task
+       │    └─ terminate subprocess (SIGTERM)
+       └─ loop.create_task(client.shutdown())
+            └─ RPC SHUTDOWN → Box Runtime 清理所有容器
+```
+
+Box 额外做了 RPC SHUTDOWN 通知 Runtime 主动清理容器，比 Plugin 的直接杀进程更安全。

+
+## 6. 配置
+
+### config.yaml (重构后)
+
+```yaml
+box:
+    enabled: true         # 整个 Box 子系统的总开关。设为 false 时：
+                          #  - 不连接远程 Box runtime，不 fork 本地 stdio 子进程
+                          #  - sandbox 工具 (exec/read/write/edit/glob/grep) 不暴露给 LLM
+                          #  - skill 添加/编辑 / GitHub 安装 / 文件写入全部拒绝
+                          #  - stdio 模式的 MCP server 启动时报错（http/sse 模式不受影响）
+                          #  - skill 列表/读取保持只读可用
+                          # BOX__ENABLED 环境变量可覆盖（统一约定）
+    backend: 'local'      # 'local' (探测) / 'docker' / 'nsjail' / 'e2b'
+                          # 由 box.backend / BOX__BACKEND 选择后端
+    runtime:
+        endpoint: ''      # 外部 Runtime 的 WS 基地址 'ws://host:5410'
+                          # 留空 = 本地自管 Runtime
+    local:
+        profile: 'default'
+        image: ''                       # 覆盖 profile 默认 image
+        host_root: './data/box'         # 工作区挂载根，Docker 部署需绝对路径
+        default_workspace: ''           # 默认 '<host_root>/default'
+        skills_root: 'skills'           # Box 管理的 skill 包目录（相对 host_root）
+        allowed_mount_roots:            # 默认 ['<host_root>']
+            - './data/box'
+            - '/tmp'
+        workspace_quota_mb: null        # 配额覆盖，null = 走 profile
+    e2b:
+        api_key: ''                     # 也可走 E2B_API_KEY 环境变量
+        api_url: ''                     # 自托管 E2B 时填写
+        template: ''                    # 默认 template ID
+```
+
+> **重大变更**: 较 2026-04-16 文档，配置结构完全重组（commit `eefdea4`）。原字段 `box.profile` / `box.runtime_url` / `box.shared_host_root` / `box.allowed_host_mount_roots` 全部迁入 `box.local.*` 子表，新增 `box.backend` 与 `box.e2b.*` 配置组。
+
+### docker-compose.yaml
+
+`langbot_box` 服务受 compose profile 控制,默认 `docker compose up` **不会**启动它。需要 sandbox 时:
+
+```bash
+docker compose --profile box up        # 启动 langbot + langbot_box + plugin runtime
+docker compose --profile all up        # 同上
+docker compose up                       # 只起 langbot + plugin runtime (box 关闭)
+```
+
+若不起 `langbot_box`,需要同步在 `data/config.yaml` 中设 `box.enabled: false`(或 langbot 容器 env 加 `BOX__ENABLED=false`),否则 LangBot 会一直尝试连接不存在的 Box runtime 并报错。
+
+```yaml
+# langbot_box 的关键 volume
+volumes:
+  - ${LANGBOT_BOX_ROOT}:${LANGBOT_BOX_ROOT}         # 工作区挂载(源/目标同路径)
+  - /var/run/docker.sock:/var/run/docker.sock       # Docker backend 复用宿主 docker
+```
+
+### 关闭/连接失败时的行为矩阵
+
+`box.enabled = false` 与"启用但连接失败"在用户可观察行为上**完全一致**——都通过 `BoxService.available = False` 表达,只是 `get_status` 多返回 `enabled` 字段供前端区分文案。
+
+| 消费方 | Box 可用 | Box 不可用(disabled 或 failed) |
+|---|---|---|
+| native exec/read/write/edit/glob/grep 工具 | 暴露给 LLM | **不暴露** |
+| `activate` / `register_skill` 工具 | 暴露给 LLM | **不暴露** |
+| stdio MCP server | 在 Box 内启动 | **`_init_stdio_python_server` 抛 RuntimeError** 拒绝;不退化到宿主 stdio |
+| http/sse MCP server | 正常 | 正常(不依赖 Box) |
+| Skill 列表/读取 (`list_skills`/`get_skill`/`read_skill_file`) | 走 Box runtime | 走 LangBot 本地 `data/skills/` 只读 fallback |
+| Skill 创建/编辑/安装/写文件 | 走 Box runtime | **HTTP 400** + 明确错误信息(`_require_box_for_write`) |
+| Pipeline AI 配置中 `box-session-id-template` | 正常生效 | **前端 banner** 提示字段无效 |
+| Pipeline 扩展页 `enable_all_skills` / 绑定 skill | 可编辑 | **前端禁用** + banner |
+| 仪表盘 Box 状态卡片 | 绿点 / "已连接" | 灰点 / "已禁用"(disabled) 或 红点 / "已断开"(failed) |
+
+> 后端拒写的边界条件:如果 `ap.box_service` **完全没装**(老式 dev mode,没经过 BuildAppStage),`_require_box_for_write` 视作 no-op,保留 `data/skills/` 本地路径——以兼容历史测试与最小化设置。生产环境总会装 `ap.box_service`,因此该 fallback 不会被触发。
+
+### Pipeline 配置 (templates/metadata/pipeline/ai.yaml)
+
+`local-agent.config.box-session-id-template` 控制 session 作用域，预设：
+
+- `{launcher_type}_{launcher_id}` — 每个会话 (推荐，默认)
+- `{launcher_type}_{launcher_id}_{sender_id}` — 群聊每个用户
+- `{launcher_type}_{launcher_id}_{conversation_id}` — 每个对话上下文
+- `{query_id}` — 每条消息（完全隔离）
+
+详见 [box-session-scope.md](./box-session-scope.md)。
+
+### REST API
+
+| 端点 | 方法 | 说明 | 前端 |
+|------|------|------|:---:|
+| `/api/v1/box/status` | GET | 可用性、Profile、后端信息 | ✅ 监控页 |

+# Box 系统 — SaaS 发布前阻塞项
+
+> 更新日期: 2026-06-02
+> 分支: `feat/sandbox` (LangBot + langbot-plugin-sdk)
+> 相关文档: [架构分析](./box-architecture.md) | [Session 作用域](./box-session-scope.md) | [Runtime 对比](./box-vs-plugin-runtime.md) | [测试覆盖](./box-test-coverage.md) | [toB 分析](./box-tob-analysis.md)
+
+## 范围说明
+
+**自部署社区版已具备发布条件**：默认 stdio 模式、box 为可选项；box 关闭 / 不可用时后端、前端、工具、skill、stdio-MCP 均能干净降级（清晰报错、不崩溃）；配置向后兼容（旧 `data/config.yaml` 可直接启动）；无新增 ORM 模型、无迁移欠债；市场安装失败不会破坏实例。CI 全绿。
+
+本清单**只保留发布 SaaS / 多租户 / 公网暴露前必须处理的阻塞项**。社区版（可信、单运营者、内网）不受这些项阻塞——它们的风险面在"不可信调用方能直接触达 Box 控制面"或"多租户共享资源"的场景才成立。
+
+## 已解决（社区版发布前）
+
+| 项 | 处理 |
+|----|------|
+| 工具调用循环无上限 (原 #13) | `localagent.py` 增加 `MAX_TOOL_CALL_ROUNDS=128`，超限优雅终止（`cafef1a3`） |
+| 配额校验同步遍历阻塞事件循环 (原 #10) | `_enforce_workspace_quota` 改 async，工作区遍历走 `asyncio.to_thread`（`cafef1a3`） |
+| `host_path` 挂载白名单 (原 #3 的 LangBot 侧) | `pkg/box/service.py` `allowed_mount_roots` 白名单，空列表时拒绝一切宿主挂载 |
+| 重复的 `_is_path_under` (原 #12) | 已去重，仅保留一处定义 |
+| 重连 / 心跳 / Windows 兼容 / nsjail image 字段 / 前端 Box 状态接入 | 见上一轮 review 记录，均已合入 |
+
+---
+
+## SaaS 阻塞项
+
+### S1. Box 控制面无认证 — Critical
+
+- **位置**: SDK `box/server.py` — Action RPC WS (`/rpc/ws`) 与 managed-process relay (`/v1/sessions/{id}/managed-process/{pid}/ws`)
+- **现状**: 两个 WS handler 在 `ws.prepare` 后直接服务，无任何 token / 鉴权；box 默认绑定 `0.0.0.0:5410`。任何能触达该端口者可发起 `EXEC`、创建 session、attach 任意 session 的 managed-process stdin/stdout、甚至 `SHUTDOWN`。LangBot→box 的 INIT 也未下发任何凭证。
+- **缓解现状**: 默认 `docker-compose.yaml` 的 `langbot_box` 未把 5410 发布到宿主（爆炸半径限于内网 bridge）；但 box 挂载了 `/var/run/docker.sock`，同网络的任意服务（含被攻破的插件）→ 宿主 root。若运营者把 5410 发布到宿主或独立以 `0.0.0.0` 起 box，则完全裸奔。
+- **要求**: INIT 时下发 token，两个 WS 路由按连接校验（query/header）。这是 SaaS 的**头号**阻塞项。
+
+### S2. 无 exec 授权模型（policy.py 死代码） — High
+
+- **位置**: LangBot `pkg/box/policy.py`（`SandboxPolicy` / `ToolPolicy` / `ElevatedPolicy` 全项目无引用）；`pkg/provider/tools/loaders/native.py`；`pkg/provider/tools/toolmgr.py`
+- **现状**: 原生工具（`exec/read/write/edit/glob/grep`）按"box 是否可用"全有或全无地暴露，**无 per-pipeline 的 exec 网关 / 工具白名单 / 沙箱模式 / 权限提升控制**。只要 box 可用，任何使用 local-agent + 函数调用模型的 pipeline 都能跑任意 shell。
+- **要求**: 接入 policy.py（或等价机制），按 pipeline 控制是否暴露 `exec`、可用工具白名单、沙箱网络/只读模式。
+
+### S3. 会话资源无界（DoS） — High
+
+- **#5 session 数量无上限**: SDK `box/runtime.py` `_get_or_create_session` 的 `_sessions` dict 无容量限制——可变 `session_id` 的恶意调用可无限创建容器，耗尽宿主 CPU/内存/PID/磁盘。
+- **#8 无定时回收**: 过期 session 仅在 `_get_or_create_session` 时机会性清理，无独立周期任务；一波创建后转静默会永久泄漏容器。
+- **要求**: `max_sessions` 上限（拒绝或 LRU），加独立周期 reaper（如 60s）。
+
+### S4. 工作区配额无内核级限制（TOCTOU） — Med-High
+
+- **位置**: LangBot `pkg/box/service.py` `_enforce_workspace_quota`（应用层 read-then-check）；SDK 侧 `workspace_quota_mb` 仅记录/透传，无 `--storage-opt size=` 等内核/FS 限额
+- **现状**: 执行前后两次检查之间存在竞态窗口；单条命令（`dd`/`fallocate`）可在检查间隙撑爆磁盘，事后检查只能补救。
+- **要求**: Docker `--storage-opt size=` 做内核级限制，或 Redis 原子计数预留式配额。
+
+### S5. 挂载校验缺口 — Med-High
+
+- **位置**: SDK `box/security.py` `_BLOCKED_HOST_PATHS_POSIX`；`box/backend.py` 的 `extra_mounts` 处理
+- **现状**: ① SDK 黑名单仍不含 `/`（前缀匹配，`host_path="/"` 可通过，挂载整个宿主 fs）；用户 home、`/usr`、`/opt`、`/tmp` 也未拦截。② `validate_sandbox_security` 只校验 `spec.host_path`，**从不遍历 `spec.extra_mounts`**——LangBot 侧 `allowed_mount_roots` 也只校验 `host_path`。当前 `extra_mounts` 仅由 `build_skill_extra_mounts` 内部填充（agent 不可达），但缺乏纵深防御：一旦 S1 的无认证 RPC 被触达，extra_mounts 可挂任意宿主路径，两层都不拦。
+- **要求**: SDK 黑名单加入 `/`（或改白名单）；`extra_mounts` 在 SDK 与 LangBot 两侧都纳入挂载校验。
+
+### S6. 容器加固缺失 — Med
+
+- **位置**: SDK `box/backend.py` 的 `docker run` 组装
+- **现状**: 未设置 `--cap-drop=ALL`、`--security-opt=no-new-privileges`、非 root `--user`；叠加挂载 docker.sock，逃逸面偏大。
+- **要求**: 默认加上上述加固 flag（需回归常用 skill 不被破坏）。
+
+### S7. 全局锁内执行慢操作（扩展性） — Med
+
+- **位置**: SDK `box/runtime.py` `_get_or_create_session`：`self._lock` 持有期间调用 `backend.start_session()`（`docker run` / nsjail 启动 / E2B `Sandbox.create`）
+- **影响**: 冷启动（镜像拉取数秒、E2B >1s）期间串行阻塞所有并发请求——多租户负载下整个 Box runtime 停顿。降级表现是延迟而非失败。
+- **要求**: 锁内只做状态检查与注册，容器创建移到锁外。
+
+### S8. 其他硬化 / 跟进 — Low
+
+- **#9** SDK `box/server.py` 直接读 `runtime._sessions` 私有字段、绕过锁，并发下可能读到不一致状态——应加公共访问方法。
+- **#16** `pkg/provider/tools/toolmgr.py` `execute_func_call` 按优先级分发，plugin/MCP 若有同名 `exec/read/write/...` 工具会被静默遮蔽——应加命名空间或冲突告警。
+- **#4** SDK `box/runtime.py` INIT/handshake 与 backend 实例化的残留竞态（仅"纯远程 WS box 先启动、LangBot 后连"场景成立；stdio/compose 路径下 config 经 env 在 spawn 时已就位，无竞态）——应在 INIT 完成前拒绝业务 action。
+- **#11** `extra_mounts` 在容器创建时固定（SDK `runtime.py` 兼容性检查不含 extra_mounts）；长生命周期共享 session 后续新激活的 skill 不会挂上（当前缓解：创建时挂上 pipeline 绑定的全部 skill）——动态绑定场景需销毁重建或文档说明。
+- **#21** 集成测试未进 CI：容器实际执行、E2B 真机、managed-process WS attach 仅本地可跑。安全关键路径缺自动化覆盖——SaaS 前建议加 Docker-in-Docker CI stage 或合并前手动 checklist。

+# Box Session Scope Design
+
+> Date: 2026-04-18 (last reviewed 2026-06-02)
+> Status (2026-06-02): the self-hosted community edition is release-ready (box optional, clean degradation, no migration debt). Tool-call loop cap, async quota scan, and the host_path mount allowlist have landed. Remaining multi-tenant / security hardening is tracked in [box-issues.md](./box-issues.md).
+> Branch: `feat/sandbox` (LangBot + langbot-plugin-sdk)
+> Related: [Box Architecture](./box-architecture.md) | [Box vs Plugin Runtime](./box-vs-plugin-runtime.md)
+
+---
+
+## 0. Implementation Status (2026-05-19)
+
+This document was authored as a design proposal. The current `feat/sandbox` branch
+has shipped the design largely as written:
+
+| Item | Status | Notes |
+|------|--------|-------|
+| `BoxMountSpec` + `BoxSpec.extra_mounts` | ✅ Shipped | SDK `box/models.py` |
+| Docker / nsjail / E2B backends apply extra mounts | ✅ Shipped | Last gap closed by SDK commit `0fea9b1` (E2B) |
+| `box-session-id-template` in `local-agent` pipeline config | ✅ Shipped | `templates/metadata/pipeline/ai.yaml`, default `{launcher_type}_{launcher_id}` |
+| `BoxService.resolve_box_session_id(query)` | ✅ Shipped | `pkg/box/service.py:166` |
+| `BoxService.build_skill_extra_mounts(query)` | ✅ Shipped | `pkg/box/service.py:189` |
+| Skill exec uses unified container + extra mounts | ✅ Shipped | `pkg/provider/tools/loaders/native.py` skill branch |
+| MCP-in-Box uses shared persistent session, multi-process | ✅ Shipped (earlier than originally scoped) | SDK commit `529088e`, LangBot `mcp_stdio.py:_build_box_session_id` |
+| `BoxManagedProcessSpec.process_id` + multi-process per session | ✅ Shipped | `BoxRuntime` keeps `managed_processes: dict[pid, _ManagedProcess]` |
+| Per-tenant / quota integration with templates | ❌ Not started | See [box-tob-analysis.md](./box-tob-analysis.md) |
+
+The "Phase 2 deferred" note in §10 is **out of date** — MCP unification went in on
+the same line. Pipeline-scoped (not user-scoped) MCP container is the realized
+behavior: each pipeline's MCP servers share one `mcp-<pipeline>` session, and
+user exec sessions use the template-derived id.
+
+The remaining open work is multi-tenant overlays (tenant_id in session_id,
+quota counters keyed by tenant), tracked in the toB analysis doc rather than here.
+
+---
+
+## 1. Problems
+
+### 1.1 Default exec: per-message containers
+
+Currently, `BoxService.execute_tool()` sets `session_id = str(query.query_id)` — an
+auto-incrementing integer per incoming message. Every user message creates a new sandbox
+container. Dependencies installed and in-container state are lost between messages.
+
+### 1.2 Three isolated container pools
+
+Default exec, skills, and MCP servers each manage their own containers with
+independent session IDs:
+
+| Path         | Session ID                                    | Container   |
+|--------------|-----------------------------------------------|-------------|
+| Default exec | `str(query_id)` (per message)                 | Ephemeral   |
+| Skill exec   | `skill-{launcher}_{id}-{skill_name}`          | Per skill   |
+| MCP stdio    | `mcp-{server_uuid}`                           | Per server  |
+
+This means a single logical user interaction can spawn 3+ containers that cannot
+share state, see each other's files, or reuse installed dependencies.
+
+### 1.3 Single bind mount limitation
+
+`BoxSpec` currently supports only **one** `host_path` → `mount_path` bind mount.
+This prevents mounting both a default workspace and skill directories into the
+same container.
+
+---
+
+## 2. Concept Model
+
+```
+Platform Message
+  → Query (query_id: int, auto-increment, per message)
+    → Session (launcher_type + launcher_id, per chat window)
+      → Conversation (uuid, per dialogue context within a Session)
+```
+
+| Concept       | Key                                 | Example                    | Scope                        |
+|---------------|-------------------------------------|----------------------------|------------------------------|
+| Query         | `query_id`                          | `42`                       | Single message               |
+| Session       | `launcher_type` + `launcher_id`     | `group_123456`             | Chat window (group or PM)    |
+| Conversation  | `conversation_id` (UUID)            | `a1b2c3d4-...`             | Dialogue context within a Session |
+| Sender        | `sender_id`                         | `789`                      | Individual user              |
+
+Note: in a **group chat**, all users share the same Session (keyed by `group_id`). The
+individual sender is tracked as `sender_id` but does not affect Session/Conversation routing.
+
+---
+
+## 3. Target Scenarios
+
+| #  | Scenario                       | Box Granularity                          | Desired `session_id`                                   |
+|----|--------------------------------|------------------------------------------|---------------------------------------------------------|
+| 1  | Personal assistant             | 1 Box per user, long-lived               | `{launcher_type}_{launcher_id}`                          |
+| 2  | Customer service               | 1 Box per customer, cross-pipeline       | `{launcher_type}_{launcher_id}`                          |
+| 3  | Internal employee tool         | 1 Box per employee                       | `{launcher_type}_{launcher_id}`                          |
+| 4  | Group chat shared assistant    | 1 Box per group                          | `{launcher_type}_{launcher_id}`                          |
+| 5  | Group chat isolated per user   | 1 Box per user within a group            | `{launcher_type}_{launcher_id}_{sender_id}`              |
+| 6  | Teaching (cross-channel)       | 1 Box per student across groups/PMs      | `{sender_id}`                                           |
+| 7  | One-off execution              | 1 Box per message (current behavior)     | `{query_id}`                                            |
+| 8  | Multi-project development      | 1 Box per conversation context           | `{launcher_type}_{launcher_id}_{conversation_id}`        |
+
+No single fixed granularity covers all scenarios. A template-based approach is needed.
+
+---
+
+## 4. Design Overview
+
+Two key changes:
+
+1. **Unified container**: exec, skills, and MCP all share the same container per
+   session scope. No more separate container pools.
+2. **Configurable session scope**: `session_id` is generated from a template with
+   pipeline variables, configurable per pipeline.
+
+### 4.1 Unified Container with Multiple Mounts
+
+A single container per session scope is created on first use. It has:
+
+- **Primary mount**: default workspace at `/workspace` (from `default_host_workspace`)
+- **Skill mounts**: each pipeline-bound skill's `package_root` mounted at
+  `/workspace/.skills/{skill_name}/`
+- **MCP servers**: run as managed processes inside the same container
+
+```
+Container (session_id = "group_123456")
+  /workspace/                          ← default workspace (bind mount, rw)
+  /workspace/.skills/web-search/       ← skill package (bind mount, rw)
+  /workspace/.skills/data-analysis/    ← skill package (bind mount, rw)
+  [managed process: mcp-server-a]      ← MCP server running inside
+  [managed process: mcp-server-b]      ← MCP server running inside
+```
+
+This requires extending `BoxSpec` to support multiple mounts (see §5).
+
+### 4.2 Session ID Template
+
+A new field `box-session-id-template` in the `local-agent` pipeline runner config
+controls the session scope:
+
+```yaml
+# templates/metadata/pipeline/ai.yaml (under local-agent.config)
+- name: box-session-id-template
+  label:
+    en_US: Sandbox Scope
+    zh_Hans: 沙箱作用域
+  description:
+    en_US: >-
+      Determines how sandbox environments are shared. Use variables to
+      control isolation granularity.
+    zh_Hans: >-
+      决定沙箱环境的共享方式。使用变量控制隔离粒度。
+  type: select
+  required: false
+  default: "{launcher_type}_{launcher_id}"
+  options:
+    - value: "{launcher_type}_{launcher_id}"
+      label:
+        en_US: Per chat (Recommended)
+        zh_Hans: 每个会话（推荐）
+    - value: "{launcher_type}_{launcher_id}_{sender_id}"
+      label:
+        en_US: Per user in chat
+        zh_Hans: 会话中每个用户
+    - value: "{launcher_type}_{launcher_id}_{conversation_id}"
+      label:
+        en_US: Per conversation context
+        zh_Hans: 每个对话上下文
+    - value: "{query_id}"
+      label:
+        en_US: Per message (isolated)
+        zh_Hans: 每条消息（完全隔离）
+```
+
+Available template variables (populated by PreProcessor in `query.variables`):
+
+| Variable            | Source                          | Example              |
+|---------------------|---------------------------------|----------------------|
+| `{launcher_type}`   | `query.session.launcher_type`   | `person` / `group`   |
+| `{launcher_id}`     | `query.session.launcher_id`     | `123456`             |
+| `{sender_id}`       | `query.sender_id`               | `789`                |

+| `{query_id}`        | `query.query_id`                | `42`                 |
+
+Default `{launcher_type}_{launcher_id}` covers scenarios 1–4 out of the box.

+
+## 5. SDK Changes: Multi-Mount BoxSpec
+
+### 5.1 Model Extension
+
+```python
+# box/models.py
+
+class BoxMountSpec(pydantic.BaseModel):
+    """A single bind mount specification."""
+    host_path: str
+    mount_path: str
+    mode: BoxHostMountMode = BoxHostMountMode.READ_WRITE
+
+class BoxSpec(pydantic.BaseModel):
+    # ... existing fields ...
+    host_path: str | None = None              # Primary mount (backward compat)
+    host_path_mode: BoxHostMountMode = BoxHostMountMode.READ_WRITE
+    mount_path: str = DEFAULT_BOX_MOUNT_PATH
+    extra_mounts: list[BoxMountSpec] = []     # NEW: additional mounts
+```
+
+`extra_mounts` is additive — the existing `host_path` / `mount_path` pair remains
+the primary mount for backward compatibility.
+
+### 5.2 Backend: Apply Extra Mounts
+
+```python
+# box/backend.py — CLISandboxBackend.start_session()
+
+# Primary mount (unchanged)
+if spec.host_path is not None and spec.host_path_mode != BoxHostMountMode.NONE:
+    args.extend(['-v', f'{spec.host_path}:{spec.mount_path}:{spec.host_path_mode.value}'])
+
+# Extra mounts (NEW)
+for mount in spec.extra_mounts:
+    if mount.mode != BoxHostMountMode.NONE:
+        args.extend(['-v', f'{mount.host_path}:{mount.mount_path}:{mount.mode.value}'])
+```
+
+Same pattern for nsjail backend.
+
+---
+
+## 6. LangBot Changes
+
+### 6.1 Session ID Resolution
+
+In `BoxService.execute_tool()`:
+
+```python
+# Before:
+spec_payload.setdefault('session_id', str(query.query_id))
+
+# After:
+template = (query.pipeline_config or {}).get('ai', {}) \
+    .get('local-agent', {}).get('box-session-id-template',
+         '{launcher_type}_{launcher_id}')
+variables = query.variables or {}
+session_id = template.format_map(collections.defaultdict(
+    lambda: 'unknown', variables
+))
+spec_payload.setdefault('session_id', session_id)
+```
+
+### 6.2 Skill Exec: Use Same Container
+
+Currently `native.py:_invoke_exec` creates a separate `BoxWorkspaceSession` per
+skill with `host_path=package_root`. Instead:
+
+1. Use the **same session_id** as default exec (from the template).
+2. Pass the skill's `package_root` as an **extra mount** at
+   `/workspace/.skills/{skill_name}/` instead of replacing `/workspace`.
+3. The container already has the default workspace at `/workspace`.
+
+```python
+# native.py — _invoke_exec, skill branch (REVISED)
+
+# Same session_id as default exec
+session_id = resolve_box_session_id(query)
+
+spec_payload = {
+    'cmd': rewritten_command,
+    'workdir': rewritten_workdir,
+    'session_id': session_id,
+    'extra_mounts': [{
+        'host_path': package_root,
+        'mount_path': f'/workspace/.skills/{selected_skill_name}',
+        'mode': 'rw',
+    }],
+}
+result = await self.ap.box_service.execute_spec_payload(spec_payload, query)
+```
+
+The virtual path `/workspace/.skills/{name}` no longer needs rewriting at the
+command level — it maps directly to the bind mount path inside the container.
+
+### 6.3 MCP: Use Same Container
+
+MCP servers should run inside the same container as exec and skills. Changes:
+
+1. `BoxStdioSessionRuntime` uses the pipeline's session_id template instead of
+   `mcp-{server_uuid}`.
+2. MCP server's working directory is a subdirectory (e.g. `/workspace/.mcp/{name}/`).
+3. MCP server's dependencies are mounted or installed into that subdirectory.
+4. The MCP server runs as a managed process inside the shared container.
+
+Since MCP servers start at LangBot boot (not per-query), the session must be
+created eagerly. The container will be kept alive by the managed process
+exemption in TTL reaping (`runtime.py:259`).
+
+**Note**: MCP sessions are pipeline-scoped (not per-launcher), so their session_id
+should be a **fixed identifier per pipeline** rather than the user-facing template.
+This means one shared MCP container per pipeline, with user exec sessions separate.
+
+Alternatively, in a future iteration, MCP managed processes could be launched
+lazily into the user's container on first MCP tool call. This is more complex
+but maximizes sharing. For V1, keeping MCP containers at pipeline scope is
+simpler and more predictable.
+
+---
+
+## 7. Mount Layout Summary
+
+### Default exec (no skills activated)
+
+```
+Container (session_id from template)
+  /workspace/          ← default_host_workspace (rw)
+```
+
+### Exec with activated skills
+
+```
+Container (same session_id)
+  /workspace/                          ← default_host_workspace (rw)
+  /workspace/.skills/web-search/       ← skill package_root (rw)
+  /workspace/.skills/data-analysis/    ← skill package_root (rw)
+```
+
+Extra mounts are **additive** — they are added when the container is first
+created (or on the first exec that references a skill). Since Docker bind
+mounts are specified at container creation time, skills must be known at
+creation time.
+
+**Resolution**: When creating a container, inject `extra_mounts` for **all
+pipeline-bound skills** (from `extensions_preferences`), not just the
+currently activated one. This way any skill can be activated later without
+recreating the container.
+
+### MCP servers (V1: pipeline-scoped)
+
+```
+Container (session_id = "mcp-pipeline-{pipeline_uuid}")
+  /workspace/                    ← MCP shared workspace
+  /workspace/.mcp/server-a/      ← MCP server A files
+  /workspace/.mcp/server-b/      ← MCP server B files
+  [managed process: server-a]
+  [managed process: server-b]
+```
+
+---
+
+## 8. Data Migration
+
+Existing pipelines do not have `box-session-id-template`. The backend uses
+`.get(..., default)` so missing keys fall back to `{launcher_type}_{launcher_id}`.
+This changes behavior from per-message to per-launcher for existing pipelines.
+
+Recommendation: **accept the behavior change** — per-launcher is the more
+intuitive default, and the old per-message behavior was rarely desired.
+
+---
+
+## 9. Cloud Quota Implications
+
+| Scope                                         | Typical concurrent containers |
+|-----------------------------------------------|-------------------------------|
+| `{query_id}` (per message)                    | Many, short-lived             |
+| `{launcher_type}_{launcher_id}` (per chat)    | = active chat count           |
+| `{sender_id}` (per user)                      | = active user count           |
+| `{conversation_id}` (per conversation)        | Between per-chat and per-msg  |
+
+With the unified container model, each scope value maps to exactly **one**
+container (instead of potentially 3+ per-message). This significantly reduces
+resource usage.
+
+Quota enforcement point: `BoxRuntime._get_or_create_session()` in the SDK.
+
+---
+
+## 10. Implementation Phases
+
+### Phase 1: Session scope + skill unification (this PR)
+
+1. **SDK**: Extend `BoxSpec` with `extra_mounts: list[BoxMountSpec]`.
+2. **SDK**: Update Docker/nsjail backends to apply extra mounts.
+3. **LangBot**: Add `box-session-id-template` to `local-agent` YAML metadata
+   and default pipeline config JSON.
+4. **LangBot**: Update `BoxService.execute_tool()` to use template interpolation.
+5. **LangBot**: Update `native.py:_invoke_exec` skill branch to use same
+   session_id + extra mounts instead of separate `BoxWorkspaceSession`.
+6. **LangBot**: On container creation, inject extra mounts for all
+   pipeline-bound skills.
+7. **Frontend**: No code change — `DynamicFormComponent` renders `select` fields.
+8. **Tests**: Unit tests for template interpolation and multi-mount specs.
+
+### Phase 2: MCP unification (future)
+
+1. Refactor `BoxStdioSessionRuntime` to use pipeline-scoped shared container.
+2. MCP servers become managed processes in the shared container.
+3. Support multiple concurrent managed processes per container.
+
+MCP unification is deferred because it requires changes to the managed process
+model (currently 1 managed process per session) and has startup ordering
+concerns (MCP servers start at boot, before any user query determines
+a session_id).

+## 3. 覆盖缺失的区域
+
+### 3.1 零测试 / 严重不足
+
+| 区域 | 源文件 | 影响 |
+|------|--------|------|
+| **`security.py`** | SDK `box/security.py` (52 行) | `validate_sandbox_security()` 无任何测试。阻止 `/etc`/`/proc`/Docker socket 等危险挂载的安全函数从未被验证 |
+| **`policy.py`** | `pkg/box/policy.py` (98 行) | 三层安全策略无测试（也是死代码） |
+| **`skill_store.py` 边缘场景** | SDK `box/skill_store.py` (647 行) vs 测试 88 行 | GitHub 安装路径、`source_subdir` / `target_suffix` 组合、损坏 zip、文件冲突等场景未覆盖 |
+
+### 3.2 未测试的关键路径
+
+| 区域 | 说明 |
+|------|------|
+| **Session TTL 过期** | 测试配置了 `session_ttl_sec` 但从未推进时间验证过期清理 |
+| **并发 session 访问** | 无并发 exec / 并发创建 / race condition 测试 |
+| **Container backend (Docker)** | 仅通过集成测试覆盖（CI 不运行），单元测试全用 FakeBackend |
+| **E2B 真实 sandbox** | 单测全是 mock，未对接真实 E2B API |
+| **BoxRuntime shutdown()** | 在 test cleanup 中调用但未验证行为 |
+| **BoxServerHandler 错误路径** | 畸形请求、未知 action 类型 |
+| **WS relay** | 仅在集成测试中覆盖（CI 不运行） |
+| **NsjailBackend managed process** | 完全未测试 |
+| **MCP stdio 完整生命周期** | 依赖安装 → 进程启动 → 健康检查 → 多 process 并发 → 重试 |
+| **BoxService start/stop_managed_process** | 单 process 流转有单测，多 process 互不阻塞主要靠集成测试 |
+| **重连指数退避** | connector 单测覆盖回调接线，未实际跑完整重连周期 |
+
+### 3.3 边缘情况缺失
+
+| 区域 | 说明 |
+|------|------|
+| BoxSpec 校验 | 无效 session_id 格式、超长命令、env 特殊字符 |
+| BoxSpec.extra_mounts | 重复 mount_path、与 host_path 冲突、绝对 vs 相对路径 |
+| BoxExecutionResult | 仅 COMPLETED 和 TIMED_OUT，无 ERROR 状态测试 |
+| 多后端 fallback | local 模式探测顺序仅靠 mock，无真实 Docker 不可用 → nsjail 真机 fallback 测试 |
+| Profile YAML 加载 | 测试用硬编码字符串，未从真实 config.yaml 加载 |
+| INIT 配置变更触发 backend 重建 | 单测仅在初始化场景验证 |
+
+---
+
+## 4. 集成测试 vs CI 的差距
+
+CI 仅运行 `tests/unit_tests/`，以下场景**从未在自动化中验证**:
+
+- 真实容器的创建/执行/销毁
+- 容器网络隔离（`--network none`）
+- 容器资源限制生效（cpus/memory/pids_limit）
+- Managed process 的 WS 双向 I/O
+- 多 process 同 session 并发 I/O
+- 孤儿容器清理
+- Session 删除清理容器
+- 进程退出检测
+- E2B 真实 sandbox 行为
+
+**建议**: 在 CI 中加一个可选的 Docker-in-Docker 集成测试 stage，至少覆盖核心执行路径（exec / MCP attach / session 销毁）。

+---
+
+## 3. SaaS 部署架构建议
+
+### 3.1 方案 A: 共享 Box Runtime Pool (快速上线)
+
+```
+LangBot Instance ──> Box Runtime (共享)
+                       ├─ tenant_id 标签隔离
+                       ├─ Redis 配额计数器
+                       └─ Container labels: langbot.tenant_id=xxx
+```
+
+- **优点**: 改动最小，加 tenant_id 到 BoxSpec/labels 即可
+- **缺点**: 容器引擎共享，安全隔离弱
+
+### 3.2 方案 B: 每租户 K8s Namespace + gVisor (推荐中期)
+
+```
+LangBot ──> K8s API
+              ├─ namespace: tenant-xxx
+              │    ├─ RuntimeClass: gVisor (runsc)
+              │    ├─ ResourceQuota
+              │    └─ NetworkPolicy
+              └─ namespace: tenant-yyy
+                   └─ ...
+```
+
+- **优点**: 强隔离（namespace + gVisor），原生 K8s 配额
+- **缺点**: 需要重写 backend 为 K8s Job，部署复杂度高
+
+### 3.3 方案 C: K8s Job 直接编排 (长期)
+
+```
+LangBot ──> K8s Job per execution
+              ├─ 每次执行创建 Job
+              ├─ Pod Security Standards
+              ├─ 自动调度和资源分配
+              └─ Job TTL Controller 自动清理
+```
+
+- **优点**: 最强隔离，天然水平扩展
+- **缺点**: 冷启动延迟，架构重写
+
+**推荐演进路径**: A → B → C
+
+---
+
+## 4. 配额体系建议
+
+### 三层配额
+
+| 层 | 实现 | 作用 |
+|----|------|------|
+| **内核层** | Docker `--cpus`/`--memory`/`--storage-opt` | 硬性资源上限，不可绕过 |
+| **应用层** | Redis 原子计数器 | 并发 session 数/执行次数/CPU 时间预算 |
+| **计费层** | 月度聚合 | 按租户计费（session-hours/execution-count） |
+
+### Profile 与套餐映射
+
+| 套餐 | Profile | locked 字段 | 配额 |
+|------|---------|------------|------|
+| Free | `offline_readonly` | network, host_path_mode, rootfs | 10 exec/天, 0.5 CPU, 256MB |
+| Pro | `default` | (无) | 100 exec/天, 1 CPU, 512MB |
+| Enterprise | `network_extended` | (按需) | 无限, 2 CPU, 1GB, 自定义镜像 |
+
+### TOCTOU 配额修复
+
+当前 `_enforce_workspace_quota` 的 TOCTOU 问题可通过两种方式解决:
+
+1. **预留式配额** (应用层): Redis `INCRBY` 预扣额度 → 执行 → 成功则扣减，失败则回滚
+2. **内核级限制** (Docker): `--storage-opt size=500m` 直接限制容器可写层大小
+
+---
+
+## 5. 优先实施路线
+
+### Phase 1 (2-4 周): 安全基线
+
+- [ ] WS relay 加 token 认证
+- [ ] 接入或删除 policy.py
+- [x] ~~Box 加重连和心跳~~（已完成，见 [box-issues.md 已解决](./box-issues.md)）
+- [ ] 审计日志持久化（至少写文件/数据库）
+- [ ] `security.py` 加 `/` 拦截，考虑白名单
+- [ ] INIT 与 backend 初始化顺序整理（避免 backend 在配置到达前实例化）
+
+### Phase 2 (4-8 周): 多租户基础
+
+- [ ] BoxSpec 加 `tenant_id` 字段
+- [ ] 容器 labels 加 tenant 标识
+- [ ] Redis 配额计数器（并发/执行次数/时间）
+- [ ] RBAC 基础框架
+- [ ] 定时 session reaper
+
+### Phase 3 (8-16 周): 生产就绪
+
+- [ ] Prometheus metrics exporter
+- [ ] 前端 Box 状态面板
+- [ ] K8s backend 支持 (方案 B)
+- [ ] 结构化日志 (JSON, trace_id)
+- [ ] 水平扩展支持

+# Box Runtime vs Plugin Runtime: 连接架构对比
+
+> 更新日期: 2026-06-02
+> 状态更新: 自部署社区版已具备发布条件（box 可选、降级完善、无迁移欠债）；工具调用循环上限、配额遍历异步化、`host_path` 挂载白名单等已落地。剩余多租户 / 安全硬化项见 [SaaS 阻塞项清单](./box-issues.md)。
+> 分支: `feat/sandbox` (LangBot + langbot-plugin-sdk)
+
+---
+
+## 1. 总体差异
+
+| 维度 | Plugin Runtime | Box Runtime |
+|------|---------------|-------------|
+| **继承关系** | `PluginRuntimeConnector(ManagedRuntimeConnector)` | `BoxRuntimeConnector`（独立类） |
+| **传输分支** | 3 条 (Docker/WS, Win32/subprocess+WS, Unix/stdio) | 3 条 (本地 stdio, Win32/subprocess+WS, 远程 WS) |
+| **心跳** | 20s ping loop | 20s ping loop（`_heartbeat_loop`） |
+| **重连** | WS 模式: sleep 3s → re-initialize | 由 BoxService `_reconnect_loop` 处理，指数退避 |
+| **Handler 类型** | `RuntimeConnectionHandler` (1132 行, 25+ action) | 基础 `Handler` + `BoxServerHandler`（SDK 端 25 action） |
+| **Client 抽象** | Handler 即 API | 独立 `ActionRPCBoxClient` 封装 Handler |
+| **启用/禁用** | `is_enable_plugin` 开关 | 无开关（可用/不可用由初始化结果决定） |
+| **初始化失败** | 异常上抛 | 静默降级 `_available=False` |
+| **Shutdown** | 直接杀进程 | RPC SHUTDOWN → 清理容器 → 再杀进程 |
+

+
+## 2. 传输决策
+
+### Plugin: 3-路决策
+
+```python
+# pkg/plugin/connector.py:106-165
+if get_platform() == 'docker' or use_websocket_to_connect_plugin_runtime():
+    # Docker/WS → ws://langbot_plugin_runtime:5400/control/ws
+elif get_platform() == 'win32':
+    # Windows → 起子进程(无 pipe) + ws://localhost:5400/control/ws
+else:
+    # Unix/Mac → StdioClientController(python -m langbot_plugin.cli rt -s)
+```
+
+### Box: 3-路决策
+
+```python
+# pkg/box/connector.py
+if self._uses_websocket():
+    if platform.get_platform() == 'win32' and not self.configured_runtime_url:
+        await self._start_subprocess_then_ws()  # subprocess + ws://localhost:5410/rpc/ws
+    else:
+        await self._connect_remote_ws()         # ws://{host}:5410/rpc/ws
+else:
+    await self._start_local_stdio()             # StdioClientController
+```
+
+> 历史：2026-04-16 版本本文档曾把 Box 描述为 2 路决策（缺 Windows 分支）。现已对齐 Plugin 的 3 路设计。
+
+### 决策矩阵
+
+| 环境 | Plugin | Box |
+|------|--------|-----|
+| Docker | WS → `:5400` | WS → `:5410/rpc/ws` |
+| `--standalone-box` | N/A | WS → `localhost:5410/rpc/ws` |
+| Windows 非 Docker | subprocess + WS (`:5400`) | subprocess + WS (`localhost:5410/rpc/ws`) |
+| Unix/Mac 非 Docker | stdio | stdio |
+| 手动配置 URL | 通过配置项 | WS → 用户配置的 URL |
+
+---
+
+## 3. 连接建立
+
+### 同步模式差异
+
+**Plugin**: `new_connection_callback` 内直接 ping + await handler_task，`initialize()` 通过 `create_task()` 异步启动，不阻塞等待连接。
+
+**Box**: 使用 `asyncio.Event` + `wait_for(timeout=30s)` 模式，`initialize()` 同步等待连接成功或超时。
+
+### Box stdio 路径
+
+```
+connector._start_local_stdio()
+  ├─ connected = asyncio.Event()
+  ├─ ctrl = StdioClientController(python, ['-m', 'langbot_plugin.cli.__init__', 'box', '-s', '--ws-control-port', N])
+  ├─ _ctrl_task = create_task(ctrl.run(callback))
+  │    callback:
+  │      handler = Handler(connection)          ← 基础 Handler, 无 disconnect_callback
+  │      client.set_handler(handler)
+  │      _handler_task = create_task(handler.run())
+  │      call_action(PING, {})                  ← 握手, timeout=15s
+  │      connected.set()                        ← 通知外层
+  │      await _handler_task                    ← 阻塞直到断开
+  └─ await wait_for(connected.wait(), 30s)      ← 同步等待
+```
+
+### Plugin stdio 路径
+
+```
+connector.initialize()
+  ├─ ctrl = StdioClientController(python, ['-m', 'langbot_plugin.cli', 'rt', '-s'])
+  ├─ task = ctrl.run(callback)
+  │    callback:
+  │      disconnect_callback:
+  │        [WS] → runtime_disconnect_callback → 重连
+  │        [stdio] → 仅日志, 不重连
+  │      handler = RuntimeConnectionHandler(conn, disconnect_cb, ap)
+  │      create_task(handler.run())
+  │      handler.ping()                         ← 握手, timeout=10s
+  │      await handler_task                     ← 阻塞直到断开
+  ├─ create_task(heartbeat_loop())              ← 20s ping loop
+  └─ create_task(task)                          ← 不等待连接
+```
+
+---
+
+## 4. 心跳与重连
+
+### 心跳
+
+| 维度 | Plugin | Box |
+|------|--------|-----|
+| 有心跳? | 是 | 是（`connector.py` `_heartbeat_loop`） |
+| 间隔 | 20s | 20s |
+| 失败处理 | 仅 DEBUG 日志，不触发重连 | 仅 DEBUG 日志，依赖 connection close 触发重连 |
+| 生命周期 | 整个应用生命周期 | 连接建立后启动；`dispose()` 时 cancel |
+
+### 重连
+
+| 维度 | Plugin | Box |
+|------|--------|-----|
+| Docker/WS 断开 | `runtime_disconnect_callback` → sleep 3s → re-initialize | `runtime_disconnect_callback` → `BoxService._reconnect_loop()`（指数退避） |
+| WS 连接失败 | 同上 | 同上；初次失败时 `_available=False`，重连成功后恢复 |
+| stdio 断开 | 仅日志，不重连 | 接同样回调；stdio 重连需重新 fork 子进程 |
+| 重连退避 | 固定 3s，无 backoff | 指数退避 |
+
+> 历史：2026-04-16 版本本文档曾把心跳与重连标记为 Box 缺失。这两项已在 commit `2dfd9d5d` / `c6882cf` / `5029d9c` 等修复（详见 [box-issues.md 已解决](./box-issues.md)）。
+
+---
+
+## 5. 共享 IO 层
+
+两者复用同一套 SDK IO 基础设施：
+
+```
+Handler ← ABC                              (runtime/io/handler.py)
+  ├── RuntimeConnectionHandler              (Plugin 用, LangBot 侧)
+  ├── ControlConnectionHandler              (Plugin 用, SDK 侧)
+  ├── BoxServerHandler                      (Box 用, SDK 侧)
+  └── 匿名 Handler 实例                     (Box 用, LangBot 侧)
+
+Connection ← ABC
+  ├── StdioConnection    (stdio: 16KB chunks, 应用层分帧协议)
+  └── WebSocketConnection (WS: 64KB chunks, 原生 WS 分帧)
+
+Controller ← ABC
+  ├── StdioClientController    (fork 子进程, pipe stdin/stdout)
+  ├── StdioServerController    (接管当前进程 stdin/stdout)
+  ├── WebSocketClientController (连接 WS 服务端)
+  └── WebSocketServerController (监听 WS 端口)
+```
+
+共享的核心机制：
+- `call_action()` / `call_action_generator()` — RPC 调用/流式调用
+- `ActionRequest` / `ActionResponse` — 请求/响应协议
+- `seq_id` 关联 — 并发请求复用单连接
+- `CommonAction.PING` — 两者都用于初始握手
+- 文件传输 (`send_file`) — Plugin 用，Box 不用
+
+---
+
+## 6. 端口方案
+
+| 服务 | Plugin | Box |
+|------|--------|-----|
+| Action RPC (stdio) | stdin/stdout | stdin/stdout |
+| Action RPC (WS) | `:5400` | `:5410/rpc/ws` |
+| 辅助服务 | debug WS `:5401` | managed process WS relay `:5410/v1/sessions/{id}/managed-process/ws` |
+
+**Box 特点**: 单端口 aiohttp 服务（默认 5410），通过路径区分 Action RPC 和 managed process relay。即使在 stdio 模式，也在 `:5410` 启动 aiohttp 用于 managed process attach。Plugin 在 stdio 模式不开额外端口。
+
+---
+
+## 7. 销毁对比
+
+### Plugin
+
+```python
+dispose():
+  if stdio: ctrl.process.terminate()
+  _dispose_subprocess()         # Windows 子进程
+  heartbeat_task.cancel()
+```
+
+### Box
+
+```python
+connector.dispose():
+  _handler_task.cancel()
+  _ctrl_task.cancel()
+  _subprocess.terminate()
+
+service.dispose():
+  connector.dispose()
+  loop.create_task(client.shutdown())   # RPC SHUTDOWN → 清理所有容器
+```
+
+Box 的 RPC SHUTDOWN 确保容器被正确停止，不会成为孤儿。Plugin 直接杀进程。
+
+---
+
+## 8. 改进建议
+
+### P0
+
+1. **两者都加 WS 认证**: 至少 token 认证（INIT 时下发，连接时校验）
+
+### P1
+
+2. **考虑 Box 继承 ManagedRuntimeConnector**: 复用 `_start_runtime_subprocess` / `_wait_until_ready` / `_dispose_subprocess`，减少重复代码
+3. **Plugin 重连加退避**: 固定 3s 无 backoff 可能造成日志洪水，建议向 Box 的指数退避看齐
+4. **统一连接管理模式**: Event-based (Box) vs direct-await (Plugin)，考虑收敛为一种
+
+### 已完成（自上一轮）
+
+- ~~Box 加重连~~（commit `2dfd9d5d`）
+- ~~Box 加心跳~~（20s loop 与 Plugin 一致）
+- ~~Box 加 Windows 支持~~（commit `120817a` / `fafb7a4`）
