refactor(subprocess): keep terminate() as the seam's only termination verb
Delete kill(signal?) from SubprocessHandle: consumers stop a process only through terminate()'s tree-scoped SIGTERM→graceMs→SIGKILL escalation (idempotent, also driven by the spec's abort signal, a no-op once the tree is gone). The single-signal verb had exactly one consumer family — lsp-local — and what it bought there was a private re-implementation of the same escalation. The internal kill closure stays in spawn.ts as the dispose ladder's tier primitive; terminate() now routes through it too. lsp-local collapses onto the seam's escalation: - LspConnection replaces its terminate()/kill() pair with one terminate() that delegates to handle.terminate(). Behavior change: the framing-failure path terminates instead of instant SIGKILL, so a misbehaving server now gets SIGTERM plus the killGraceMs window to flush before SIGKILL. - ConnectionSpec.pipeDrainGraceMs becomes killGraceMs: one grace, the spawn spec's graceMs, drives both the escalation window and post-exit pipe draining (the provider already passed killGraceMs for it). - LspInstance.forceTerminate() drops its hand-rolled bounded first wait (LSP_KILL_GRACE) and escalateProcessTree (deleted with its export and unit test): the seam's escalation already commits to SIGKILL after killGraceMs, so only the unbounded quiescence awaits stay load-bearing. Tests: kill()-shaped spawn specs become terminate()-shaped or fold into the terminate() suites (group-wide delivery; the settled no-op case was already pinned by 'terminate() after the tree died'); tree-survivor coverage is intact. A stderr-'inherit' disposition test completes the stdout/stderr symmetry so the scoped subprocess+lsp coverage gate stands alone instead of leaning on subagent-acp's cross-package runs. Docs: SubprocessHandle type-equiv block, seam/impl/group READMEs, and the consumer-migration Agent Note lose the kill(signal?) vocabulary (zh pairs re-recorded); cordis api/services catalogs regenerated.

- **Detached process trees with platform-correct signalling** — POSIX children are spawned `detached` (own process group) and signalled by negative pgid with a direct-child fallback; Windows terminates the tree via `taskkill /PID <pid> /T /F` (injectable for tests). `terminate()` sends SIGTERM then SIGKILL after the spec's grace (OpenCode's escalation; pipelines and subshells die with the parent); `kill(signal)` sends exactly one signal and is a no-op after settlement; `dispose(graces)` runs stdin-EOF → SIGTERM → SIGKILL with caller-supplied windows and one memoized disposal per handle. After the leader exits, still-open pipes receive the same bounded drain grace so a surviving descendant cannot hold the outcome open indefinitely. ESRCH is tolerated; daemons that re-parent away from the group can still survive — the same caveat as the surveyed tools.

|
||||
- **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 + managed `DSH_*` merge** — `process.env` minus credential-shaped vars (`*KEY*`/`*SECRET*`/`*TOKEN*`) and all ambient `DSH_*` names; a spec's ordinary `env` merges after the scrub but rejects `DSH_*`; managed `dshEnv` rejects ordinary names and merges last, preventing stale nested-harness identity. 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.

## 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()` 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）；`kill(signal)` 恰好发送一个信号，结算后为空操作；`dispose(graces)` 以调用方提供的时间窗运行 stdin EOF→SIGTERM→SIGKILL 阶梯，dispose（资源释放）按句柄 memoize 化、只执行一次。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 + 受管 `DSH_*` 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 的普通 `env` 在清除后合并，但会拒绝 `DSH_*`；受管 `dshEnv` 会拒绝普通名称并最后合并，防止陈旧的嵌套 harness 身份。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。

|

- 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`): `kill(signal)` sends one signal Node-style and is a no-op after settlement, `terminate()` (and the spec's abort signal) escalates SIGTERM→grace→SIGKILL, `waitForExit()` observes the whole tree, and `dispose(graces)` runs the cooperative stdin-EOF→SIGTERM→SIGKILL ladder out-of-process children need — the manager reacts but never classifies why (callers own deadlines and cause classification).

- 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()` 观察整棵进程树；`dispose(graces)` 运行进程外子进程所需的协作式 stdin EOF→SIGTERM→SIGKILL 阶梯。管理器只响应中止，但绝不判定原因（deadline 与原因分类归调用方所有）。
|
||||
- `scrubbedParentEnv()` / `SENSITIVE_ENV_PATTERN` 是唯一一份共享的凭据清除定义：环境中形似凭据的名称与 `DSH_*` 名称都会被丢弃，显式 `env` 在清除之后合并（有意转发的键会保留下来），`dshEnv` 则经由自身带校验的通道携带当前 harness 事实；`splitEnvChannels()` 把消费方配置中单一的混合 env 映射按这两条通道切分（lsp-local 的服务器配置与 ACP 后端只暴露一个映射，而配置的 `DSH_*` 事实必须走受管通道，普通通道会拒绝它）。无法把 spawn 路由到该服务的调用点（node-pty 后端、由 SDK 管理的传输层）改为导入凭据清除函数。
|
||||
- 服务自身的 dispose（资源释放）会终止所有仍在运行的受管进程并等待其退出。
