docs: purge chain-of-thought leakage from prose

Delete design-session citations (decision/audit/plan ordinals, stack positions), change narration, review choreography, and reviewer-addressed justification from comments, JSDoc, docs, READMEs, Agent Notes, tests, and generator templates; restate every affected fact as current-state contract prose. Fix generated docs at their sources and regenerate the catalogs and cordis-surface regions; re-paste type-equiv blocks; update every bilingual counterpart and re-record the pairs. Record the citation rule in the committed-artifact-citations Agent Note.

 Local Service provider for the [`@deepseek-ai/dsh-subprocess`](../subprocess/README.md) seam. `LocalSubprocessService` resolves local executables, spawns ordinary detached process trees with explicit stdio, and implements terminal processes through `node-pty` plus platform process inspection. It has no config: every disposition, limit, terminal dimension, grace, and directory arrives from the calling capability seams ([`dsh-bash-local`](../../bash/bash-local/README.md), [`dsh-lsp-local`](../../lsp/lsp-local/README.md), and [`dsh-pty-local`](../../pty/pty-local/README.md)).

-## Behavior (and where it came from)
+## Behavior

- **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`. `terminate()` — the handle's only termination verb — sends SIGTERM then SIGKILL after the spec's grace (OpenCode's escalation; pipelines and subshells die with the parent) and is a no-op once the tree is gone; `waitForExit()` polls whole-tree liveness so consumer teardown confirms real quiescence. 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.

ESRCH is tolerated; daemons that re-parent away from the group can still survive.
 - **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*`/`*PASSWORD*`/`*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.

 [`@deepseek-ai/dsh-subprocess`](../subprocess/README.md) seam 的本地 Service provider。`LocalSubprocessService` 解析本地可执行文件，以显式 stdio spawn 普通 detached 进程树，并通过 `node-pty` 加平台进程检查实现终端进程。该实现没有任何配置：每项处置方式、限制、终端尺寸、宽限期与目录都来自调用方能力 seam（[`dsh-bash-local`](../../bash/bash-local/README.md)、[`dsh-lsp-local`](../../lsp/lsp-local/README.md) 和 [`dsh-pty-local`](../../pty/pty-local/README.md)）。

-## 行为（以及设计来源）
+## 行为

- **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。`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。

 - **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` 则只保留用于诊断的尾部。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，位于按需创建、权限为 `0700` 的每进程目录之下。
 - **凭据清除 + 显式合并**：以 `process.env` 为基础，移除形似凭据的变量（`*KEY*`／`*PASSWORD*`／`*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](../../../.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**：收集模式的读取器按完整流的字节坐标返回增量；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。
