+# Agent Note: Inspector development mount
+
+Status: implemented
+
+English | [中文](2026-08-27-inspector-development-mount.zh.md)
+
+## Problem
+
+`@deepseek-ai/dsh-experimental-inspector` is a private package no published dsh installation carries, yet development launches need to mount it into the shipped Web composition on demand. A row in a shipped bundle patch cannot express this: `verify-cordis-config` requires every named row of a bundle patch to resolve from that bundle's own `dependencies` — disabled rows included — and a published manifest must not depend on an unpublished package.
+
+## Decision
+
+The inspector package owns a development overlay, `packages/experimental/inspector/cordis.patch.yml`, holding a single `insert` of the `experimental-inspector` row. A launch selects it through the generic overlay flag; `pnpm run demo:inspector` is the shorthand for `pnpm dsh web --patch ./packages/experimental/inspector/cordis.patch.yml`.
+
+The overlay contributes only the row; the row's module resolves from the profile plane at entry import:
+
+- A source launch (`pnpm dsh`, tsx) resolves the workspace package through the tsconfig `paths` facade and needs no installation.
+- A built launch (`node apps/cli/lib/bin.js`) needs the package importable from the profile first: `dsh plugin --profile web add link:<absolute package path>`, once per profile. `link:` keeps dependency resolution inside the real package directory; `file:` re-installs the package's `workspace:^` dependencies in the profile and fails with `ERR_PNPM_WORKSPACE_PKG_NOT_FOUND`.
+
+A launch whose profile cannot import the package fails loud at entry import (`Cannot find package '@deepseek-ai/dsh-experimental-inspector' imported from <profile dir>`); nothing is skipped silently.
+
+## Consequences
+
+Published packages carry no trace of the inspector: no manifest entry, no composition row, no launcher flag. Mounting stays a per-launch choice — the same service without the overlay never loads the package — and every layer the launch composes is declared in a config file. The cost is launch-mode asymmetry: a built launch needs the one-time profile `link:` install, and the overlay must be named on every invocation, which `pnpm run demo:inspector` absorbs for the common case.
+
+## Alternatives considered
+
+- A `disabled: !!js` row in the shipped web-app patch: the dependency gate and npm publication both force the private package into the published manifest.
+- A `--inspector` launcher flag mounting the package as an extra bundle layer: the launcher owns neither app flags nor plugin package names.
+- An optional `peerDependencies` entry on `dsh-web-app` plus a dynamic `ctx.loader.create` from its glue plugin: it writes a never-published name into a published manifest and mounts a row no config layer declares.

+# Agent Note：Inspector 开发挂载
+
+Status: implemented
+
+[English](2026-08-27-inspector-development-mount.md) | 中文
+
+## Problem
+
+`@deepseek-ai/dsh-experimental-inspector` 是任何已发布 dsh 安装都不携带的 private 包，但开发启动需要按需把它挂进随货 Web 组合。随货 bundle patch 里的一行表达不了这件事：`verify-cordis-config` 要求 bundle patch 中每个具名行都能从该 bundle 自己的 `dependencies` 解析——disabled 行也不豁免——而已发布的 manifest 不得依赖未发布的包。
+
+## Decision
+
+inspector 包自有一份开发 overlay，`packages/experimental/inspector/cordis.patch.yml`，只含一个 `insert` 的 `experimental-inspector` 行。启动通过通用 overlay flag 选它；`pnpm run demo:inspector` 是 `pnpm dsh web --patch ./packages/experimental/inspector/cordis.patch.yml` 的简写。
+
+overlay 只贡献这一行；行的模块在 entry import 时从 profile 平面解析：
+
+- 源码启动（`pnpm dsh`，tsx）经 tsconfig `paths` 门面解析 workspace 包，无需任何安装。
+- built 启动（`node apps/cli/lib/bin.js`）需先让包可从 profile import：`dsh plugin --profile web add link:<包目录绝对路径>`，每个 profile 一次。`link:` 让依赖解析留在真实包目录内；`file:` 会在 profile 里重装该包的 `workspace:^` 依赖并以 `ERR_PNPM_WORKSPACE_PKG_NOT_FOUND` 失败。
+
+profile 无法 import 该包的启动会在 entry import 处响亮失败（`Cannot find package '@deepseek-ai/dsh-experimental-inspector' imported from <profile dir>`）；不存在静默跳过。
+
+## Consequences
+
+已发布的包不携带 inspector 的任何痕迹：没有 manifest 条目、没有组合行、没有 launcher flag。挂载保持按次启动选择——不带 overlay 的同一服务永远不会加载该包——且启动组合的每一层都由 config 文件声明。代价是启动方式不对称：built 启动需要一次性 profile `link:` 安装，且每次调用都要点名 overlay，常见场景由 `pnpm run demo:inspector` 吸收。
+
+## Alternatives considered
+
+- 随货 web-app patch 里放 `disabled: !!js` 行：依赖门禁与 npm 发布都会把 private 包逼进已发布 manifest。
+- `--inspector` launcher flag 把包挂成额外 bundle 层：launcher 既不拥有 app flag 也不拥有插件包名。
+- `dsh-web-app` 上加 optional `peerDependencies` 并由其 glue 插件动态 `ctx.loader.create`：向已发布 manifest 写入永不发布的名字，且挂载的行不在任何 config 层声明。
