The opt-in E2B realization has exactly three provider-specific packages under `packages/e2b/`: `dsh-e2b` creates one sandbox and deletes it on timeout or disposal, `dsh-fs-e2b` implements `ctx.fs`, and `dsh-subprocess-e2b` implements `ctx.subprocess` over E2B Commands, PTYs, and remote Linux process groups. The two adapters obtain the sole SDK handle from the owner and never create private sandboxes.
|
||||
|
||||
E2B owns the mutable filesystem, managed command and Bash processes, terminal allocation and terminal-session groups, language-server processes and source reads, and adapter-private files under `.dsh-e2b`. The host owns Cordis and plugin objects, the agent loop, agent/session/goal state, session logs and persistence, LLM calls, prompts and tools, authority, skills, subagent orchestration, PTY buffers and readiness, LSP protocol state, the worker-backed Code Runtime and its program/binding/output policy, and E2B SDK/network buffers. The overlay neither uploads nor synchronizes the host workspace.

The adapters retain only substrate mechanics. Filesystem canonicalization crosses the SDK's decoded command transport as strict base64-encoded NUL framing; streamed reads leave byte ceilings with consumers. Subprocess command output and environment snapshots use ASCII/base64 where SDK chunk decoding would otherwise lose bytes, while private control shells isolate profiles and later launches blank discovered credential-shaped names. Process and terminal cleanup uses remote groups and proves quiescence before settlement.

可选启用的 E2B 实现在 `packages/e2b/` 下恰好只有三个提供方专用包：`dsh-e2b` 创建一个沙箱，并在超时或资源释放时将其删除；`dsh-fs-e2b` 实现 `ctx.fs`；`dsh-subprocess-e2b` 基于 E2B Commands、PTY 和远程 Linux 进程组实现 `ctx.subprocess`。两个适配器都从所有者取得唯一的 SDK 句柄，绝不创建私有沙箱。

E2B 负责可变文件系统、受管命令与 Bash 进程、终端分配与终端会话组、语言服务器进程与源文件读取，以及 `.dsh-e2b` 下的适配器私有文件。宿主负责 Cordis 与插件对象、agent loop（智能体循环）、agent（智能体）状态、会话状态与目标状态、会话日志与持久化、LLM（大语言模型）调用、提示词与工具、权限、skill（技能）、subagent 编排、PTY 缓冲区与就绪状态、LSP 协议状态、基于 worker 的代码运行时及其程序／绑定／输出策略，以及 E2B SDK／网络缓冲区。该叠加层既不上传，也不同步宿主工作区。

适配器只保留执行基底机制。文件系统规范化以严格的 base64 加 NUL 分帧穿过 SDK 已解码的命令传输；流式读取把字节上限留给消费方执行。进程管理命令输出与环境快照采用 ASCII/base64，避免 SDK 分片解码丢失字节；私有控制 shell 隔离 profile，后续启动会把已发现且名称呈凭据特征的环境变量置空。进程与终端清理使用远程进程组，并在结算前证明完全停稳。
