Subject: [PATCH] refactor(subprocess): rename the process seam to subprocess
 and address review
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review feedback (tianyicui): 'process' is a poor service name. The family is
now packages/subprocess/ — @deepseek-ai/dsh-subprocess (ctx.subprocess,
abstract SubprocessService, Subprocess* vocabulary) and
@deepseek-ai/dsh-subprocess-local (LocalSubprocessService) — renamed
throughout code, compositions, docs (en+zh, pairs re-recorded), catalogs,
and gates. 'subprocess' is the precise term for managed OS children (the
Python-stdlib sense), avoids colliding with Node's global process object,
and reads as one system beside dsh-subagent-subprocess.

ds-review-bot findings addressed:
- kill() on a settled handle is now a no-op (no signal to a possibly-reused
  pgid, no referenced grace timer delaying exit); pinned by a spy test.
- The moved DshEnvironmentKey/DshEnvironment/CollectedOutput types get
  drift-checked type-equiv blocks on the new subprocess.md page, restoring
  their manifest registration.
- subprocess.md is registered in the core.md sub-page index (en+zh).

 Timeout handling was drifting apart across the tool-bearing capabilities, and the divergence was not superficial — it was the same logic re-implemented three ways, each with its own subtle correctness burden.
 
-- **bash** (then in the bash-local implementation's `run.ts`) had a full, correct timeout inside the process plumbing: a config-clamped `timeoutMs`, two independent triggers — a `killTimer` for the timeout and an `onAbort` listener for upstream cancellation — each calling one `kill()` closure that escalates SIGTERM→grace→SIGKILL on the process group, and two orthogonal outcome booleans (`timedOut`, `aborted`) latched independently. After this consolidation, the plumbing — today [packages/process/process-local/src/spawn.ts](../../../../packages/process/process-local/src/spawn.ts) — only reacts to aborts; [packages/bash/bash-local/src/index.ts](../../../../packages/bash/bash-local/src/index.ts) owns the fused deadline and the `timedOut`/`aborted` classification.

 - **web_search** ([packages/web/tool-web/src/search.ts](../../../../packages/web/tool-web/src/search.ts)) had **no timeout at all**: `WebSearchRequest` ([packages/web/web/src/types.ts](../../../../packages/web/web/src/types.ts)) carries no `timeoutMs` field, and each provider's `search()` only forwards `exec.signal`. (web_search stays untimed here — see Consequences.)

 超时处理在各个承载工具的能力之间逐渐分化，而且这种分化并非表面的：同一套逻辑被以三种方式重新实现，各自带有微妙的正确性负担。

-# Agent Note: The process manager is its own seam under the bash executors (`dsh-process` / `dsh-process-local`)
-
-Status: implemented
-
-English | [中文](2026-07-26-process-manager-seam.zh.md)

-## Problem
-
-`dsh-bash-local` bundled two capabilities that change for different reasons: *running a bash command* (command defaulting, timeout classification, model-friendly terminal environment, the stdout/stderr merge the bash tool renders) and *running and managing a child process* (detached process groups, bounded tail-keep output with spill files, the credential scrub and `DSH_*` merge order, SIGTERM→grace→SIGKILL escalation, kill-and-join disposal). The process half — `run.ts`, roughly half the package — had no seam of its own: a future non-shell runner (a direct-argv executor, a worker supervisor) would have to re-implement or reach into bash internals, and the shared `DSH_*`/`CollectedOutput` vocabulary lived in a package whose name promises shell semantics. The bundling also tied background-process lifetime to the executor's fiber: reloading the bash executor killed every live background process, unlike the sibling [task registry](2026-07-26-task-registry-seam.md), whose registrations deliberately outlive producer fibers.
-
-## Decision
-
-A new `process/` capability family owns "run and manage a process"; the bash family keeps "run a bash command" and consumes it:
-
-- **`@deepseek-ai/dsh-process` (interface)** — the abstract `ProcessManager` owning `ctx.processes` with one method, `spawn(spec): ProcessHandle`, and the shared vocabulary: the fully-explicit `ProcessSpawnSpec` (argv, cwd, per-stream caps, spill cap, grace — no defaults; deployment-varying knobs stay with the calling seam's config, per the `dsh-bash` request/spec template and the no-hidden-defaults rule), `ProcessHandle` with non-consuming offset-based readers, `ProcessOutcome` with deliberately no timeout/cancel classification, and the `DSH_ENV_PREFIX`/`DshEnvironment`/`CollectedOutput` types. `argv` is never shell-interpreted.
-- **`@deepseek-ai/dsh-process-local` (implementation)** — `LocalProcessManager` over the former `run.ts` plumbing (`spawn.ts`): detached groups, tail-keep truncation with private bounded spill files, credential scrub with the two-channel `DSH_*` merge, group kill escalation, and disposal that kills and joins every still-running managed process. It has no config; every limit arrives on the spec. The terminal `ENV_OVERRIDES` (`TERM=dumb` etc.) did NOT move — that is bash-tool presentation policy and stays in `dsh-bash-local`, merged through the ordinary env channel.
-- **`dsh-bash-local` (consumer)** — `inject: ['processes']`; maps each resolved `BashExecSpec` onto a `ProcessSpawnSpec` (`['bash', '-c', command]`), keeps its config, `resolve()` defaulting, fused-deadline `timedOut`/`aborted` classification, the `[stderr]`-marked background read merge with its consuming cursor, and the `onProcessDone` subclass hook. `dsh-bash-sandbox` is unchanged apart from redeclaring the inherited inject; it still wraps at the command-string level and re-enters the inherited spawn path.
-- **`dsh-bash` (seam)** — re-exports the moved vocabulary from `dsh-process`, so no bash consumer changes an import; `BashExecRequest`/`BashExecSpec`/`BashProcess` and the sandbox facts remain bash-owned.
-
-Every composition that loads a bash executor now also loads `@deepseek-ai/dsh-process-local` (CLI, examples, python bundled runtime, create-sdk's bash feature resources, inline test configs).
-
-Background-process lifetime moved from the executor to the manager: the executor no longer retains a live-process set, so an executor reload leaves background work running and readable, and composition teardown (the manager's disposal) remains the kill-and-join boundary. One behavioral seam shifted with it: a background spawn failure can no longer be buffered as fake stderr inside the plumbing (the manager rejects `done` and buffers nothing for a process that never ran), so the executor injects the `spawn failed: …` note into exactly one `readOutput()` delta.
-
-## Alternatives considered
-
-**Leave the process plumbing inside `dsh-bash-local` (status quo).** Rejected for the same reason the [task registry split](2026-07-26-task-registry-seam.md) landed: the boundary is stable and already documented in-code (`run.ts`'s module doc said "this layer reacts to an abort signal; the executor owns deadlines and classifies causes"), and keeping it private makes every future non-shell runner either fork the mechanics or depend on a bash-named package for non-bash work. The user-visible driver for this stack was exactly this split.
-
-**Migrate the repo's other spawn sites (lsp-local, pty-local, subagent-subprocess, sdk package-manager, test-support launchers) onto `ctx.processes` in the same change.** Rejected as scope creep with real design risk: those sites have materially different stream and lifecycle needs — node-pty ownership (pty), LSP framing over long-lived stdio with tree-kill fallbacks (lsp), stdin-EOF-first disposal ladders and no output buffering (subagent transports) — and forcing them under a handle shaped for bounded batch output would either bloat the seam or misfit the consumers.

+# Agent Note: The subprocess service is its own seam under the bash executors (`dsh-subprocess` / `dsh-subprocess-local`)
+
+Status: implemented
+
+English | [中文](2026-07-26-subprocess-seam.zh.md)
+
+## Problem
+
+`dsh-bash-local` bundled two capabilities that change for different reasons: *running a bash command* (command defaulting, timeout classification, model-friendly terminal environment, the stdout/stderr merge the bash tool renders) and *running and managing a child process* (detached process groups, bounded tail-keep output with spill files, the credential scrub and `DSH_*` merge order, SIGTERM→grace→SIGKILL escalation, kill-and-join disposal). The process half — `run.ts`, roughly half the package — had no seam of its own: a future non-shell runner (a direct-argv executor, a worker supervisor) would have to re-implement or reach into bash internals, and the shared `DSH_*`/`CollectedOutput` vocabulary lived in a package whose name promises shell semantics. The bundling also tied background-process lifetime to the executor's fiber: reloading the bash executor killed every live background process, unlike the sibling [task registry](2026-07-26-task-registry-seam.md), whose registrations deliberately outlive producer fibers.
+
+## Decision
+
+A new `process/` capability family owns "run and manage a process"; the bash family keeps "run a bash command" and consumes it:
+
+- **`@deepseek-ai/dsh-subprocess` (interface)** — the abstract `SubprocessService` owning `ctx.subprocess` with one method, `spawn(spec): SubprocessHandle`, and the shared vocabulary: the fully-explicit `SubprocessSpawnSpec` (argv, cwd, per-stream caps, spill cap, grace — no defaults; deployment-varying knobs stay with the calling seam's config, per the `dsh-bash` request/spec template and the no-hidden-defaults rule), `SubprocessHandle` with non-consuming offset-based readers, `SubprocessOutcome` with deliberately no timeout/cancel classification, and the `DSH_ENV_PREFIX`/`DshEnvironment`/`CollectedOutput` types. `argv` is never shell-interpreted.
+- **`@deepseek-ai/dsh-subprocess-local` (implementation)** — `LocalSubprocessService` over the former `run.ts` plumbing (`spawn.ts`): detached groups, tail-keep truncation with private bounded spill files, credential scrub with the two-channel `DSH_*` merge, group kill escalation, and disposal that kills and joins every still-running managed process. It has no config; every limit arrives on the spec. The terminal `ENV_OVERRIDES` (`TERM=dumb` etc.) did NOT move — that is bash-tool presentation policy and stays in `dsh-bash-local`, merged through the ordinary env channel.
+- **`dsh-bash-local` (consumer)** — `inject: ['subprocess']`; maps each resolved `BashExecSpec` onto a `SubprocessSpawnSpec` (`['bash', '-c', command]`), keeps its config, `resolve()` defaulting, fused-deadline `timedOut`/`aborted` classification, the `[stderr]`-marked background read merge with its consuming cursor, and the `onProcessDone` subclass hook. `dsh-bash-sandbox` is unchanged apart from redeclaring the inherited inject; it still wraps at the command-string level and re-enters the inherited spawn path.
+- **`dsh-bash` (seam)** — re-exports the moved vocabulary from `dsh-subprocess`, so no bash consumer changes an import; `BashExecRequest`/`BashExecSpec`/`BashProcess` and the sandbox facts remain bash-owned.
+
+Every composition that loads a bash executor now also loads `@deepseek-ai/dsh-subprocess-local` (CLI, examples, python bundled runtime, create-sdk's bash feature resources, inline test configs).
+
+Background-process lifetime moved from the executor to the subprocess service: the executor no longer retains a live-process set, so an executor reload leaves background work running and readable, and composition teardown (the service's disposal) remains the kill-and-join boundary. One behavioral seam shifted with it: a background spawn failure can no longer be buffered as fake stderr inside the plumbing (the service rejects `done` and buffers nothing for a process that never ran), so the executor injects the `spawn failed: …` note into exactly one `readOutput()` delta.
+
+## Alternatives considered
+
+**Leave the process plumbing inside `dsh-bash-local` (status quo).** Rejected for the same reason the [task registry split](2026-07-26-task-registry-seam.md) landed: the boundary is stable and already documented in-code (`run.ts`'s module doc said "this layer reacts to an abort signal; the executor owns deadlines and classifies causes"), and keeping it private makes every future non-shell runner either fork the mechanics or depend on a bash-named package for non-bash work. The user-visible driver for this stack was exactly this split.
+
+**Migrate the repo's other spawn sites (lsp-local, pty-local, subagent-subprocess, sdk package-manager, test-support launchers) onto `ctx.subprocess` in the same change.** Rejected as scope creep with real design risk: those sites have materially different stream and lifecycle needs — node-pty ownership (pty), LSP framing over long-lived stdio with tree-kill fallbacks (lsp), stdin-EOF-first disposal ladders and no output buffering (subagent transports) — and forcing them under a handle shaped for bounded batch output would either bloat the seam or misfit the consumers. The seam ships proven against its one real consumer family, per the shape-interfaces-around-current-consumers rule; the others are named as deferred work in the seam README.
+
+**Put `run_in_background`/task semantics into the process seam instead.** Rejected: that boundary already exists — `ctx.tasks` owns ids, ownership, and notices, and the bash tool adapts a `BashProcess` into task hooks. The process seam sits *below* the bash executor, not beside the task registry.
+
+**Move `ENV_OVERRIDES` (TERM=dumb, PAGER=cat …) into the subprocess service.** Rejected: a generic subprocess service must not impose terminal presentation policy on non-terminal consumers; the scrub and `DSH_*` channel rules are security/identity invariants and stay, but terminal friendliness is the bash tool's choice, expressed through the ordinary env channel where an explicit caller entry still wins.

 Design surveyed against the bash tools of Claude Code, OpenCode, Codex, and pi; the notable choices:
 
 - **Spawn per call, no shell state** — every call is a fresh non-login `bash -c` (deterministic; no rc files). All four surveyed tools spawn per call. `XXX(stateful-shell)` in `src/index.ts` records the two proven stateful designs (Claude Code's cwd-only persistence; Codex's PTY exec sessions) for when real workflows demand them.
-- **Configured budgets over managed groups** — `resolve()` fills `workdir`/`timeoutMs`/`stdoutMaxBytes` from config, and every spawn hands the manager explicit byte caps, spill cap, and `graceMs` (default 3s — OpenCode's escalation). Process-group kills, the post-exit pipe-drain grace, tail-keep truncation, and bounded spill files are [`dsh-process-local`](../../process/process-local/README.md) mechanics. A foreground `BashExecRequest.stdoutMaxBytes` can raise stdout's capture budget for one trusted caller; stderr and background runs still use `maxOutputBytes`.

A foreground `BashExecRequest.stdoutMaxBytes` can raise stdout's capture budget for one trusted caller; stderr and background runs still use `maxOutputBytes`.
 - **Timeout and cancel classification** — `run()` fuses its config-clamped timeout with the caller's signal through one deadline; only the executor's own timeout reports `timedOut`, an upstream cancel reports `aborted`, and a self-signaled command reports neither ([timeout-library Agent Note](../../../.agents/notes/implemented/architecture/2026-07-06-timeout-deadline-library.md)).
-- **Model-friendly terminal env** — `NO_COLOR=1 TERM=dumb PAGER=cat GIT_PAGER=cat` (Codex's hardcoded set) so pagers and ANSI color don't garble results, merged as ordinary env under the manager's credential scrub and `DSH_*` channel rules; an explicit caller entry still wins. 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).
-- **Background processes** — `start()` returns a live `BashProcess` handle immediately, no timeout applies (Claude Code detaches timeouts when backgrounding), and the handle's `readOutput()` merges the manager's offset-based stdout/stderr reads into one marked-section delta with a consuming cursor. A still-running process belongs to the manager, so it survives executor reloads and dies (killed and joined) with the manager's disposal. Everything task-shaped (ids, ownership, polling, notices) lives in the generic [`ctx.tasks` runtime](../../tasks/tasks/README.md), which the tool layer registers the handle with — this executor never sees a session or a registry.

-Local-subprocess implementation of the [`@deepseek-ai/dsh-process`](../process/README.md) manager seam: `LocalProcessManager` spawns each spec's argv as a detached process group, collects bounded output with size-limited full-stream spill files, and escalates kills SIGTERM→SIGKILL across the whole group. It has no config: every limit and directory arrives on the spawn spec, so the deployment-varying knobs stay with the calling seam's config ([`dsh-bash-local`](../../bash/bash-local/README.md) today).
+Local implementation of the [`@deepseek-ai/dsh-subprocess`](../subprocess/README.md) seam: `LocalSubprocessService` spawns each spec's argv as a detached process group, collects bounded output with size-limited full-stream spill files, and escalates kills SIGTERM→SIGKILL across the whole group. It has no config: every limit and directory arrives on the spawn spec, so the deployment-varying knobs stay with the calling seam's config ([`dsh-bash-local`](../../bash/bash-local/README.md) today).
 
 ## Behavior (and where it came from)
 
 - **Detached process groups with escalation** — children are spawned `detached` (own process group); kills send SIGTERM to the group, then SIGKILL after the spec's grace (OpenCode's escalation; pipelines and subshells die with the parent). After the leader exits, inherited stdout/stderr pipes receive the same bounded drain grace so a surviving descendant cannot hold the spawn open indefinitely. ESRCH is tolerated; daemons that re-parent away from the group can still survive — the same caveat as the surveyed tools.
 - **Tail-keep truncation + bounded spill files** — output beyond a stream's cap keeps the in-memory TAIL (errors and results cluster at the end — pi/OpenCode rationale) while the FULL stream is appended to a private temp file whose path is reported when available. A stream larger than the spill cap discards its now-incomplete spill and returns only the marked truncated tail; 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** — `ProcessHandle` readers return deltas in whole-stream byte coordinates; the manager never holds a cursor, so consumer-owned cursors (the bash background read path) and full-stream re-reads coexist.
-- **Kill-and-join disposal** — the manager retains live handles only so its own disposal can kill every running group and await its exit; settled and spawn-failed handles leave the live set on settlement.

-The child-process manager seam (`ctx.processes`). The abstract `ProcessManager` exposes one method — `spawn(spec): ProcessHandle` — plus the vocabulary shared by every consumer: the fully-explicit `ProcessSpawnSpec`, `ProcessHandle` with its non-consuming offset-based output readers, `ProcessOutcome`, `CollectedOutput`, and the managed `DSH_*` environment namespace (`DSH_ENV_PREFIX`, `DshEnvironment`). The local implementation lives in [`dsh-process-local`](../process-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 and rejects only for spawn-level failures.
-- The spec is fully explicit — argv, cwd, per-stream byte caps, spill cap, grace — because deployment-varying defaults belong to the calling seam's config, not to a hidden process-manager default (the `dsh-bash` request/spec split is the owning template). `argv` is never shell-interpreted here; a consumer that wants a shell passes `['bash', '-c', command]` itself.

 - Output readers take whole-stream byte offsets and never consume: 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 full-stream spill file when one exists.
-- `kill()` and the spec's abort signal escalate SIGTERM→grace→SIGKILL across the whole detached group; the manager reacts to the abort but never classifies why (callers own deadlines and cause classification).
+- `kill()` and the spec's abort signal escalate SIGTERM→grace→SIGKILL across the whole detached group; the service reacts to the abort but never classifies why (callers own deadlines and cause classification).
