Turtle 82728808d4 feat(bundle): the web and one-shot apps own their own flags
dsh-web-app owns --host/--port/--dev/--workspace-root/--trusted-host and
its --help in a web-startup row; the rows it configures wait for the
webStartup service, and the client-plugin HMR receiver now ships disabled
so --dev is a row toggle rather than a runtime insert (the Loader cannot
resolve a row inserted from inside a mounting plugin).

dsh-headless owns the task positional and rejects a missing task as its own
usage error. Its runner ships disabled, not merely waiting: the schema
requires the task, and a row's config is validated when its fiber is
created, before the startup row can supply one. A composition has exactly
one command-line owner, so the patch disables the web startup row and this
one provides webStartup too, leaving the web rows on their composed
one-shot values.

The keyless web scaffold provides the same three values with no arguments,
which is what an embedding host with no command line does.

# `@deepseek-ai/dsh-web-app`
[English](README.md) | 中文
dsh 浏览器表层组合包。[`cordis.patch.yml`](cordis.patch.yml) 叠加在 [`dsh-base`](../base/README.md) 之上:设置 coding persona,插入 Web 宿主行(webserver、API 网关、workspace、投影缓存、存储)与浏览器插件名录,并挂载本包的 `web-runtime` 粘合插件(配置为 `{mode, printUrl, surfaceContext, lanAddresses}`)。该插件通过 `@deepseek-ai/dsh-frontend` 的 exports 解析已构建的前端 dist,挂载 [`frontend-static`](../../host/frontend-static/README.md) 回退席位所有者,在 `surfaceContext` 为 true 时注册 web 表层提示词段落和 bash 可见的 `DSH_WEB_URL`/`DSH_WEB_MODE` 运行时变量,并在 `printUrl` 为 true 时打印 `dsh web:` URL 行。本组合包还持有应用命令行:`web-startup` 行([`src/startup.ts`](src/startup.ts))从 `ctx.cmdlineArgs`([`dsh-cmdline`](../../boot/cmdline/README.md))解析 `--host`、`--port`、`--dev`、`--workspace-root` 以及可重复的 `--trusted-host`,并打印应用自己的 `--help`。它所配置的每一行都注入 `webStartup`,因此在参数解析完成之前不会有任何东西绑定端口,`dsh --profile web --help` 也不会启动服务器。`mode` 与 `lanAddresses` 在每次 boot 时解析,因为它们描述的是本次调用。[`dsh-headless`](../headless/README.md) 是同一 base 之上的同级表层,不挂载本组合包。
## 模型体验
### Web 表层提示词段落与 bash 运行时变量
#### 模型看到的内容
当 `surfaceContext` 为 true 时,全局段落 `app:web-surface`(顺序 −98)向模型说明 GUI:规范的本地 URL、「this page」指代什么、当前模式下 HMR(热模块替换)/重建的更新约定,以及不要启动替代服务器的指令。`DSH_WEB_URL` 与 `DSH_WEB_MODE` 还会连同各自描述出现在受管 bash 环境中,每次调用时从运行中的服务器解析。当它为 false 时,该提示词段和这些变量都不会注册。
#### Token 影响
每个会话一段提示词,外加两行受管环境变量;每个进程内保持恒定。
#### KV Cache 影响
该提示词段落位于系统提示词靠前位置,且在进程整个生命周期内稳定(端口与模式是启动期事实),因此不会使跨轮次缓存失效。
## 已知限制与延期工作
- **前端 dist 必须已构建**:对 dist 的 `require.resolve` 在激活时明确报错并给出构建提示;没有从源码直接服务的回退路径。
- **`lanAddresses` 是启动期快照**:启动后的网卡变化不会重新公告;打印的 LAN URL 始终与配置的信任栅栏一致。
