|

- `dsh-bash-local` continues to map Bash semantics onto ordinary `ctx.subprocess.spawn()`.
|
||||
- `dsh-lsp-local` reads and contains source through `ctx.fs`, resolves and launches language servers through `ctx.subprocess`, and carries provider-owned file URIs through initialization and result rendering. One provider-lifetime signal aborts filesystem and protocol work during disposal, including workspace lookup before queue ownership; its JSON-RPC, pooling, synchronization, and normalization stay unchanged.
|
||||
- `dsh-pty-local` maps persistent-shell semantics onto `ctx.subprocess.spawnTerminal()`. The local `node-pty` and process-inspection implementation moves into `dsh-subprocess-local`; another subprocess provider supplies the same primitive. `danger-full-access` needs no `ctx.sandbox`; a confined mode requires a same-world sandbox provider and fails before spawn when none is mounted. Prompt and silence evidence collected during asynchronous pre-write inspection is discarded when the provider write begins. Cancellation retains the send reservation while an in-flight write settles and then signals the foreground group, so late bytes or the signal cannot target a successor; an in-flight readiness poll cannot release that reservation, and a rejected write sends no signal. The absolute deadline remains armed throughout cancellation. A signal failure becomes terminal transport failure. Completion of a stale inspection resumes polling for the current send. Startup cancellation begins terminal rollback without waiting for a stalled readiness or signalling call. Close rejects new public signals and delegates provider-observable session quiescence to the handle's awaited termination operation.
|
||||
- `dsh-code-runtime-subprocess` materializes a dependency-free runner through `ctx.fs` and launches it through `ctx.subprocess`, preserving the Code Runtime binding and output contract across local or remote worlds. The fixed runner is adapter-owned infrastructure below `ctx.subprocess.runtimeRoot`, so its write carries an explicit `danger-full-access` policy instead of inheriting the model-facing filesystem mode. It shares host-side worker mechanics through the non-plugin `dsh-code-runtime-worker/runtime-host` subpath instead of copying them. Preparation carries one lifecycle signal through filesystem resolution, materialization, and executable lookup so disposal can abort a stalled provider. The heap-bounded worker rejects oversized binding frames before transfer, each outer hop enforces the same bound before forwarding, and raw subprocess pipes carry newline-delimited UTF-8 JSON without a redundant base64 representation. The launcher publishes an accepted terminal frame before reaping its controller so a descendant that inherits controller pipes cannot suppress completion; the host still awaits process-group quiescence.

1. **Code Mode is a first-class presentation mode of `ToolRegistry`** (`dsh-tools`), selected by a validated `mode` config: `'native'` (the default, contributing the visible capability schemas), `'code'` (the registry contributes only its reserved `run_code` transport plus a generated SDK `.d.ts` in the system prompt), or `'both'` (native schemas and the transport + SDK). The registry shapes its canonical contribution at the source; the cooperative prompt-assembly result remains authoritative, and the logged request header records exactly that returned presentation.
|
||||
2. **Code execution is a capability seam** — `packages/code-runtime/` contains the interface package `@deepseek-ai/dsh-code-runtime`, which owns `ctx.codeRuntime` ([capability seams](../architecture/2026-06-13-capability-seams.md); consumer = `dsh-tools`, with core-consumes-a-seam precedent in `agent-loop` → `dsh-llm`). The runtime knows nothing about tools: it is handed a program and named async bindings, runs the program, and reports `{ value, logs, error? }`. Language and substrate are backend properties, so a future Python or container backend is another implementation package, not a redesign.
|
||||
3. **Two implementations preserve one fresh-worker contract**: `@deepseek-ai/dsh-code-runtime-worker` runs the worker in the harness process, while `@deepseek-ai/dsh-code-runtime-subprocess` materializes a runner through `ctx.fs` and launches it through `ctx.subprocess` for another execution world. Both execute host-stripped TypeScript in a fresh Node worker with an empty environment, bridged bindings, configurable heap/output/time caps, and hard termination. Their trust posture is bash-equivalent by design; stronger isolation comes from the mounted execution world.

Expiry, cancellation, and completion terminate the worker, and heap exits or outer overflow are explicit failures.

The [portable execution-world decision](../architecture/2026-07-28-portable-execution-world-consumers.md) owns why this generic backend replaces provider-specific Code Runtime packages; `dsh-code-runtime-worker` remains the single-process and single-file-distribution path.

- **Per-stream dispositions** — `'pipe'` hands the raw stream to the caller untouched (protocol framing stays consumer-owned); `'inherit'` passes the parent descriptor through; collect mode keeps the in-memory TAIL beyond its cap (errors and results cluster at the end — pi/OpenCode rationale) while the FULL stream is appended to a private temp file when a spill cap is configured — omitting `spill` keeps only the tail, the diagnostic shape. A stream larger than the spill cap discards its now-incomplete spill and returns only the marked truncated tail; spill fds are sealed at settlement, and a failed final close withholds the path rather than advertising an incomplete file. Spill files are `0600` with random names under a lazily-created `0700` per-process directory.
|
||||
- **Credential scrub + explicit merge** — `process.env` minus credential-shaped vars (`*KEY*`/`*SECRET*`/`*TOKEN*`) and all ambient `DSH_*` names; the spec's explicit `env` merges after that scrub with no namespace validation, so a deliberately supplied credential or current `DSH_*` fact wins while stale nested-harness identity cannot leak in ambiently. Supplied stdin is written and closed; otherwise fd 0 is `/dev/null`. See the [stdin/env Agent Note](../../../.agents/notes/implemented/architecture/2026-06-30-bash-stdin-env-trusted-plugin-surface.md) and [managed environment Agent Note](../../../.agents/notes/implemented/feature/2026-07-10-agent-session-identity-and-log-location.md).

- **Offset-based reads** — collect-mode readers return deltas in whole-stream byte coordinates; the service never holds a cursor, so consumer-owned cursors (the bash background read path) and full-stream re-reads coexist, before and after settlement.
|
||||
- **Execution-world coordinates** — `cwd` is the host process cwd, `runtimeRoot` is an owner-private temporary directory removed on disposal before any process-cleanup failure is reported, and `resolveExecutable` checks absolute files or searches the scrubbed effective PATH with platform-aware executable extensions.

- **Terminal-process ownership** — `spawnTerminal` allocates `node-pty`, bridges UTF-8 terminal text, inspects and signals the current foreground process group, and exposes one awaited termination operation that sweeps descendants before and after terminating the top-level shell. Each foreground inspection retains exact identities from the rooted tree; Linux also enumerates the POSIX session after its leader exits. A previously observed macOS descendant and any same-session Linux member therefore remain fenced after reparenting, while pid/start identity prevents cleanup from following PID reuse. The higher PTY backend owns prompt readiness, buffers, and model-facing operations.
|
||||
- **Terminate-and-join disposal** — the service retains live handles only so its own disposal can escalate every running tree and await its exit; settled and spawn-failed handles leave the live set on settlement.

## 行为（以及设计来源）
|
||||
|
||||
- **带平台正确信号发送的 detached 进程树**：POSIX 子进程使用 `detached` spawn（拥有独立进程组），信号以负 pgid 发送并以直接子进程作为回退；Windows 通过 `taskkill /PID <pid> /T /F` 终止进程树（可为测试注入）。`terminate()`（句柄唯一的终止动词）先发送 SIGTERM，经过 spec 的宽限期后再发送 SIGKILL（沿用 OpenCode 的升级策略；管道与子 shell 会随父进程一起结束），进程树消亡后为空操作；`waitForExit()` 轮询整棵进程树的存活状态，使消费方的拆卸能确认真正的完全停稳。组长进程退出后，仍然打开的管道也只获得同样有界的排空宽限期，因此存活的后代进程无法无限期地拖住结果不结算。系统会容忍 ESRCH；脱离该组重新挂载的 daemon 仍可能存活，这与调研工具的局限相同。
|
||||
- **按流划分的处置方式**：`'pipe'` 把原始流原样交给调用方（协议分帧仍归消费方所有）；`'inherit'` 直通父进程的描述符；收集模式（collect）在输出超过上限后于内存中保留尾部（错误与结果通常聚集在末尾，沿用 pi/OpenCode 的理由），并在配置了 spill 上限时把完整流追加到一个私有临时文件；省略 `spill` 则只保留尾部，即诊断尾部的形状。某条流大于 spill 上限时，会丢弃已不完整的 spill，仅返回带截断标记的尾部；spill 文件描述符在结算时封存，最终关闭失败时则不公布路径，以免声称存在不完整的文件。spill 文件权限为 `0600`、名称随机，位于按需延迟创建的 `0700` 每进程目录之下。
|
||||
- **凭据清除 + 显式合并**：以 `process.env` 为基础，移除形似凭据的变量（`*KEY*`／`*SECRET*`／`*TOKEN*`）和所有环境中已有的 `DSH_*` 名称；spec 的显式 `env` 在该清除之后合并且不做命名空间校验，因此有意提供的凭据或当前 `DSH_*` 事实会胜出，而陈旧的嵌套 harness 身份无法从环境中隐式漏入。提供的 stdin 会被写入后关闭；否则 fd 0 指向 `/dev/null`。参见 [stdin/env Agent Note（agent 决策记录）](../../../.agents/notes/implemented/architecture/2026-06-30-bash-stdin-env-trusted-plugin-surface.md)与[受管环境 Agent Note](../../../.agents/notes/implemented/feature/2026-07-10-agent-session-identity-and-log-location.md)。
|
||||
- **基于偏移量的读取**：收集模式的读取器以全流字节坐标返回增量；服务自身从不持有游标，因此消费方自有的游标（bash 的后台读取路径）与完整流重读可以共存，结算前后皆然。
|
||||
- **执行世界坐标**：`cwd` 是宿主进程 cwd，`runtimeRoot` 是所有者私有的临时目录，会在资源释放时删除，并且删除发生在报告任何进程清理失败之前；`resolveExecutable` 检查绝对文件，或使用平台感知的可执行扩展名在清理后的有效 PATH 中查找。
|
||||
- **终端进程所有权**：`spawnTerminal` 分配 `node-pty`，桥接 UTF-8 终端文本，检查当前前台进程组并向其发送信号，并公开一项须等待的终止操作，该操作会在终止顶层 shell 前后清理后代。每次前台检查都会保留有根进程树中的精确身份；Linux 还会在会话 leader 退出后枚举该 POSIX 会话。因此，先前观察到的 macOS 后代以及任何同会话 Linux 成员在重新设定父进程后仍受身份围栏保护，而 pid／启动身份可防止清理因 PID 复用而跟随到其他进程。上层 PTY 后端负责提示符就绪检测、缓冲和面向模型的操作。
|
||||
- **先终止再等待退出的 dispose**：服务保留存活句柄，只为让自身的 dispose 能对每个仍在运行的进程树执行升级并等待其退出；已结算与 spawn 失败的句柄在结算时即离开存活集合。
|
||||
- **以适合平台的方式发送信号的 detached 进程树**：POSIX 子进程使用 `detached` spawn（拥有独立进程组），信号以负 pgid 发送并以直接子进程作为回退；Windows 通过 `taskkill /PID <pid> /T /F` 终止进程树（可为测试注入）。`terminate()`（句柄唯一的终止操作）先发送 SIGTERM，经过 spec 的宽限期后再发送 SIGKILL（沿用 OpenCode 的升级策略；流水线与子 shell 会随父进程一起结束），进程树消亡后为空操作；`waitForExit()` 轮询整棵进程树的存活状态，使消费方的拆卸能确认真正的完全停稳。组长进程退出后，仍然打开的管道也只获得同样有界的排空宽限期，因此存活的后代进程无法无限期地拖住结果不结算。系统会容忍 ESRCH；重新指定父进程并脱离该组的 daemon 仍可能存活，这与所调研工具的局限相同。

## 已知限制与暂缓事项
|
||||
|
||||
- **Windows 进程树支持仅为尽力而为，且未经 CI 测试**：终止经由 `taskkill /PID <pid> /T /F` 完成，所有结果都被就地吸收，不向外抛出（进程树已不存在、竞态、二进制缺失），存活探测则回退到直接子进程边界；测试套件只通过注入的运行器覆盖这条路由，且 `packages/subprocess/*` 被排除在 Windows 测试矩阵之外。
|
||||
- **终端进程检查仅支持 Linux／macOS**：检查器没有受支持的平台实现时，终端原语会失败；Linux 精确探针覆盖 x64 与 arm64，macOS 使用 `ps` 快照。
|
||||
- **守护化的终端后代仍可能逃出可观察边界**：在 macOS 上，子进程若在任何前台检查快照产生前重新设定父进程，便无法再从 `node-pty` 根发现；在 Linux 上，调用 `setsid` 的子进程会同时离开进程树与该提供方拥有的终端会话。本地提供方不会增加持续运行的进程表监视器。
|
||||
- **凭据清除依赖名称启发式规则**：只匹配 `*KEY*`／`*SECRET*`／`*TOKEN*`；名称不同的 secret（例如 `*PASSWORD*`）会继续传递，对误删变量引入白名单属于已记录的后续工作。

|
||||
- **不会删除已完成的 spill 文件**：有界的完整输出恢复文件（以及每个进程的私有 spill 目录）会在 OS tmpdir 下累积，直到外部机制进行清理；超大的不完整 spill 会被丢弃并立即尝试删除，但清理失败可能留下一个有界文件。

The subprocess seam (`ctx.subprocess`) is the process half of one execution world. The abstract `SubprocessService` exposes its canonical `cwd`, private `runtimeRoot`, executable lookup, ordinary managed `spawn`, and one terminal-process primitive; its vocabulary covers raw/collected stdio, process and terminal handles, exit facts, tree/session cleanup, and the managed `DSH_*` environment namespace. The local implementation lives in [`dsh-subprocess-local`](../subprocess-local/README.md).

The local implementation lives in [`dsh-subprocess-local`](../subprocess-local/README.md).
|
||||
|
||||
## Contract
|
||||
|
||||
- `spawn(spec)` returns immediately with a live handle; `done` resolves at process close with exit facts (`SubprocessOutcome` carries no output and no cause classification) and rejects only for spawn-level failures.
|
||||
- `cwd` and `runtimeRoot` are absolute paths in the provider's execution world. Consumers materialize private helpers below `runtimeRoot`, never in a host-only temp directory. `resolveExecutable(command, env?, signal?)` verifies absolute commands or resolves bare names against that world's scrubbed PATH plus explicit overrides.
|
||||
- `cwd` and executable paths belong to the provider's execution world. `resolveExecutable(command, env?, signal?)` verifies absolute commands or resolves bare names against that world's scrubbed PATH plus explicit overrides.
|
||||
- The spec is fully explicit — argv, cwd, per-stream stdio dispositions, grace — because deployment-varying defaults belong to the calling seam's config, not to a hidden subprocess-service default (the `dsh-bash` request/spec split is the owning template). `argv` is never shell-interpreted; a consumer that wants a shell passes `['bash', '-c', command]` itself.
|
||||
- Stdio is Node-shaped per stream: `'pipe'` hands the caller the raw stream for its own protocol framing (LSP JSON-RPC, ACP ndjson), `'inherit'` passes the parent descriptor through for diagnostics, and collect mode (`{ maxBytes, spill? }`) buffers a bounded tail with an optional full-stream spill file. Collect readers take whole-stream byte offsets and never consume, so independent readers cannot steal one another's deltas; a read whose offset slid out of the in-memory tail is `lossy` and points at the spill file when one exists. Collected output stays readable after settlement.
|
||||
- Termination is tree-scoped on every platform (POSIX detached groups with direct-child fallback; Windows `taskkill /T`): `terminate()` — the only termination verb — escalates SIGTERM→grace→SIGKILL (idempotent, driven by the spec's abort signal too, a no-op once the tree is gone), and `waitForExit(signal?)` observes whole-tree liveness so a consumer-owned teardown ladder holds each tier on real quiescence — the manager reacts but never classifies why (callers own deadlines, teardown ladders, and cause classification).

子进程 seam（`ctx.subprocess`）是一个执行世界的进程部分。抽象的 `SubprocessService` 公开其规范化 `cwd`、私有 `runtimeRoot`、可执行文件查找、普通受管 `spawn` 和一项终端进程原语；其词汇涵盖原始／收集式 stdio、进程与终端句柄、退出事实、进程树／会话清理，以及受管的 `DSH_*` 环境命名空间。本地实现位于 [`dsh-subprocess-local`](../subprocess-local/README.md)。

|
||||
|
||||
## 契约
|
||||
|
||||
- `spawn(spec)` 立即返回一个活动句柄；`done` 在进程关闭时以退出事实 resolve（`SubprocessOutcome` 不携带输出，也不携带原因分类），仅在 spawn 层面失败时 reject。
|
||||
- `cwd` 和 `runtimeRoot` 是提供方执行世界中的绝对路径。消费方在 `runtimeRoot` 之下物化私有辅助程序，绝不使用仅宿主可见的临时目录。`resolveExecutable(command, env?, signal?)` 验证绝对命令，或根据该执行世界清理后的 PATH 加显式覆盖来解析裸名称。
|
||||
- `cwd` 和可执行文件路径属于提供方的执行世界。`resolveExecutable(command, env?, signal?)` 验证绝对命令，或根据该执行世界清理后的 PATH 加显式覆盖来解析裸名称。
|
||||
- spec 完全显式（argv、cwd、按流划分的 stdio 处置方式（disposition）、宽限期），因为随部署变化的默认值属于调用方 seam 的配置，而不属于某个隐藏的子进程默认值（`dsh-bash` 的 request/spec 拆分是这条规则的所属模板）。`argv` 绝不经过 shell 解释；需要 shell 的消费方自行传入 `['bash', '-c', command]`。
|
||||
- stdio 按流采用 Node 风格：`'pipe'` 把原始流交给调用方做自己的协议分帧（LSP 的 JSON-RPC、ACP（Agent Client Protocol）的 ndjson），`'inherit'` 直通父进程描述符以承载诊断输出，收集模式（collect）`{ maxBytes, spill? }` 则缓冲一段有界尾部，外加可选的完整流 spill 文件。收集模式的读取器接受全流字节偏移量且从不消费，因此独立的读取器不会抢走彼此的增量；偏移量滑出内存尾部窗口的读取标记为 `lossy`，并在 spill 文件存在时指向它。收集到的输出在结算后仍可读取。
|
||||
- 终止在每个平台上都以进程树为范围（POSIX 用 detached 进程组并以直接子进程回退；Windows 用 `taskkill /T`）：`terminate()`（唯一的终止动词）执行 SIGTERM→宽限期→SIGKILL 升级（幂等，也由 spec 的 abort 信号驱动，进程树消亡后为空操作）；`waitForExit(signal?)` 观察整棵进程树的存活状态，使消费方自有的拆卸阶梯能在真正完全停稳后才进入下一层。管理器只响应中止，但绝不判定原因（deadline、拆卸阶梯与原因分类归调用方所有）。
