 - **Linux process groups** — a quoted wrapper starts each argv under `exec setsid --wait` and records its actual process-group id plus private status files beneath `ctx.e2b.runtimeRoot/processes`. The handle waits for that file instead of treating the SDK command PID as its published identity. Termination signals the negative recorded id with `SIGTERM`, waits the caller's `graceMs`, then escalates to `SIGKILL` and the SDK kill fallback; TERM delivery or probe failures also force that escalation. Process-table probes treat groups containing only zombie or dead entries as quiescent. Force cleanup succeeds only after a bounded probe finds the group empty; otherwise `waitForExit()` exposes a retryable failure, while proven quiescence makes later termination a no-op. Publication and monitoring failures apply the same cleanup transaction before rejecting. Service disposal rejects new starts, terminates and joins every retained process group, then awaits SDK settlement and private cleanup before the sandbox owner disposes.
 - **Environment boundary** — one trusted control-shell probe resolves the sandbox user's login home from its passwd entry and transports the sandbox environment as base64 ASCII for one strict UTF-8 decode; the wrapper then removes ambient `DSH_*` and credential-shaped (`*KEY*`, `*SECRET*`, `*TOKEN*`) names and restores every valid `spec.env` entry as an explicit caller opt-in. Empty names, `=`, and NUL framing violations reject before launch. Subsequent E2B command and PTY login shells receive a fresh randomized root-level `HOME` plus empty overrides for every scrubbed ambient name before user profiles can run; the requested argv receives the serialized environment afterward without changing the sandbox user's umask. Host ambient variables never enter the sandbox implicitly. Private environment files are removed after consumption, and failed command or terminal setup removes its private state before rejecting.
 - **Stdio projection** — the remote wrapper branches raw bytes into optional bounded spill files, frames each live chunk as newline-delimited base64 ASCII, and the host incrementally restores bytes across arbitrary SDK callback boundaries. Pipe mode writes those bytes to host Node streams; inherit mode writes them to the harness process streams; collect mode retains a bounded host tail with offset reads. The wrapper publishes the direct command status before waiting for inherited writers. For collect or inherit output, the adapter disconnects an incomplete SDK stream after `graceMs`, withholds its partial spill, and returns that status while retaining the remote group for `waitForExit()` and termination. Natural raw-pipe completion instead awaits lossless transport and preserves backpressure; explicit termination destroys the host pipes and releases blocked output before remote cleanup. Batch and streaming stdin use the SDK handle.
-- **Terminal sessions** — `spawnTerminal()` uses E2B's byte PTY API, installs the exact argv and scrubbed environment through private mode-`0600` files, reports the foreground process group, sends real signals, and tears down every live group in the remote terminal session through one retryable awaited `terminate()`; termination rejects new handle operations, aborts and joins in-flight writes, inspections, and signals, and treats zombie-only groups as quiescent. A private random output boundary discards the E2B bootstrap shell's prompt and echoed runner command while preserving every requested-process byte, including its first prompt. Terminal output is pushed to the handle's stream without awaiting host backpressure: a flowing consumer (the PTY backend attaches one at construction) folds bytes into its own bounded state, while a paused consumer buffers in host memory. PTY allocation is awaited through handle publication before cancellation is observed, so owned rollback can clean the published handle. Setup and teardown own the private state transaction, abort pending setup during service disposal, and fence publication; sandbox disposal or timeout bounds a setup rollback that also fails. Prompt detection, scrollback, readiness, and owner policy remain in `dsh-pty-local`.

Prompt detection, scrollback, readiness, and owner policy remain in `dsh-terminal-bash`.
 - **Sandbox disappearance** — `SandboxNotFoundError` during process or terminal liveness, termination, rollback, or disconnect proves the remote execution world cannot retain work, so cleanup treats it as quiescent; unrelated failures remain observable.
 
 The default E2B base image supplies the runtime and Bash/GNU utilities this adapter invokes: `node`, `bash`, `setsid`, `ps`, `awk`, `tr`, `env`, `base64`, `chmod`, `tee`, `head`, `rm`, `kill`, `id`, and `getent`.

 - **Linux 进程组**：带引号保护的包装层会在 `exec setsid --wait` 下启动每组 argv，并在 `ctx.e2b.runtimeRoot/processes` 下记录实际进程组 ID 和私有状态文件。句柄会等待该文件，而不会把 SDK 命令 PID 当作已发布的身份。终止操作以记录的负数 ID 发送 `SIGTERM`，等待调用方的 `graceMs`，再升级到 `SIGKILL` 和 SDK kill 回退；TERM 信号发送或探测失败也会强制触发该升级。进程表探测会把仅含僵尸或已死亡条目的进程组视为完全停稳。强制清理只有在有界探测发现进程组为空后才算成功；否则 `waitForExit()` 会公开可重试的失败，而已证明的完全停稳会让后续终止操作不再执行任何动作。发布失败与监控失败都会在拒绝前执行同一清理事务。服务 dispose（资源释放）会拒绝新的启动请求、终止并等待每个保留进程组退出，再等待 SDK 结算和私有清理完成，之后沙箱所有者才会释放沙箱。
 - **环境边界**：一次受信任的控制 shell 探测会从 passwd 条目解析沙箱用户的登录主目录，以 base64 ASCII 传输沙箱环境，再进行一次严格 UTF-8 解码；随后包装层移除环境中的 `DSH_*` 和形似凭据的名称（`*KEY*`、`*SECRET*`、`*TOKEN*`），并把每个有效的 `spec.env` 条目恢复为调用方显式选择。空名称、`=` 和违反 NUL 分帧规则的条目会在启动前被拒绝。在用户 profile 脚本运行前，此后的 E2B 命令 shell 与 PTY 登录 shell 会获得位于根目录下、全新随机生成的 `HOME`，并为每个被清理的环境变量名设置空值覆盖；之后，请求的 argv 会在不改变沙箱用户 umask 的前提下接收序列化环境。宿主环境变量绝不会隐式进入沙箱。私有环境文件在使用后会被删除；命令或终端设置失败时，会先删除其私有状态再拒绝。
 - **stdio 投影**：远程包装层先把原始字节分流到可选的有界 spill 文件，再把每个实时分片编码为换行分隔的 base64 ASCII 帧；宿主会跨任意 SDK 回调边界增量恢复字节。pipe 模式把这些字节写入宿主 Node 流；inherit 模式把字节写入 harness 进程流；collect 模式保留有界的宿主尾部，并支持基于偏移量读取。包装层会在等待继承管道的写入方之前发布直接命令状态。对于 collect 或 inherit 输出，超过 `graceMs` 后，适配器会断开未完成的 SDK 流，不公开其中不完整的 spill，并返回该状态，同时保留远程进程组供 `waitForExit()` 和终止操作使用。原始 pipe 自然完成时，会等待无损传输完成并保留背压；显式终止则会销毁宿主 pipe，并在远程清理前释放受阻的输出写入。批量 stdin 和流式 stdin 都使用 SDK 句柄。
-- **终端会话**：`spawnTerminal()` 使用 E2B 的字节 PTY API，以 mode 为 `0600` 的私有文件传入原样 argv 与清理后的环境，报告前台进程组，发送真实信号，并通过一项可重试且须等待的 `terminate()` 清理远程终端会话中仍存活的每个进程组；终止会拒绝新的句柄操作，中止并等待在途写入、检查和信号操作结算，并把仅含僵尸进程的进程组视为已经完全停稳。私有随机输出边界会丢弃 E2B 引导 shell 的提示符和回显的 runner 命令，同时保留请求进程的每个字节，包括其第一个提示符。终端输出推入句柄流时不等待宿主背压：流动的消费方（PTY 后端在构造时就挂上一个）把字节折叠进自身的有界状态，而暂停的消费方会在宿主内存中缓冲。在句柄发布前会一直等待 PTY 分配完成，之后才观察取消，以便由承担清理责任的回滚清理已发布句柄。setup 与 teardown 负责私有状态事务，在服务 dispose 期间中止待处理的 setup 并阻止发布；若 setup 回滚也失败，则由沙箱 dispose 或超时约束其存活时间。提示符检测、scrollback、就绪状态与所有者策略仍归 `dsh-pty-local` 所有。
