 The automation-only ACP stdio application as a `dsh` profile bundle over [`dsh-base`](../base/README.md). It inherits the base's disabled module-HMR policy; its patch sets the coding-agent persona and default model route, mounts an app-owned zero-option command provider, and starts [`dsh-acp`](../../acp/acp/README.md) only after that provider accepts the invocation. `dsh --profile acp --help` therefore writes help and exits without claiming stdin or stdout.
 
-The startup provider binds stdin EOF to the launcher's bounded successful shutdown. ACP connection close, SIGINT, and SIGTERM drain the bridge-owned agents and the root profile tree before exit. Stdout is reserved for newline-delimited ACP JSON-RPC frames. The bundle disables model-generated session titles because ACP exposes no title surface; deterministic fallback titles remain durable without an auxiliary model request. A deployment selects a different complete composition through profile bundles and patch files, not another app bin.

Stdout is reserved for newline-delimited ACP JSON-RPC frames. The bundle disables model-generated session titles because ACP exposes no title surface; deterministic fallback titles remain durable without an auxiliary model request. It also keeps the base projection cache disabled: ACP exposes no session-listing surface, and the cache's write-behind would force session-log flushes at cache-chosen times, changing the durable JSONL batching this profile's keyless transcripts pin. A deployment selects a different complete composition through profile bundles and patch files, not another app bin.
 
 The shipped row creates sessions with `deepseek-official` and `deepseek-v4-flash`; a later patch can replace that row's complete config. The base profile owns adapters, tools, persistence, policy, settings, credentials, and the per-session workspace supplied by the ACP client.

 以 [`dsh-base`](../base/README.zh.md) 为基础的 automation-only ACP stdio 应用 `dsh` profile 组合包。它继承 base 默认禁用模块 HMR（热模块替换）的策略；其 patch 设置 coding agent（编程智能体）persona 与默认模型路由、挂载应用自有的零选项命令提供方，并且只在该提供方接受调用后启动 [`dsh-acp`](../../acp/acp/README.zh.md)。因此，`dsh --profile acp --help` 会写出 help 并退出，不会占用 stdin 或 stdout。
 
-启动提供方把 stdin EOF 绑定到启动器的有界成功关闭。ACP 连接关闭、SIGINT 与 SIGTERM 会在退出前排空 bridge 自有 agent 以及根 profile 树。Stdout 仅保留给换行分隔的 ACP JSON-RPC frame。ACP 不提供 title 表层，因此本组合包禁用模型生成的 session title；确定性的 fallback title 仍会持久化，但不发起辅助模型请求。部署方通过 profile 组合包与 patch 文件选择另一套完整组合，而不是使用另一个 app bin。

 随附配置项使用 `deepseek-official` 与 `deepseek-v4-flash` 创建 session；后续 patch 可以替换该配置项的完整 config。base profile 负责适配器、工具、持久化、策略、settings 与 credentials；ACP client 为每个 session 提供工作区。
