The host side of the dsh web GUI: the API gateway every client shape shares, and the plain HTTP server it rides on. The browser side lives in client/; the composed application is apps/cli booting the dsh-base bundle serving apps/web. All product packages.

Package	Role	ctx key
`apiproxy/`	Shared host API gateway and wire contract	`ctx.apiProxy`
`webserver/`	HTTP route carrier	`ctx.webServer`
`frontend-static/`	SPA dist server on the webserver fallback seat	consumes `ctx.webServer`
`directory-picker/`	Workspace-directory picking seam	`ctx.directoryPicker`
`directory-picker-native/`	Native directory-picker backend and browser interaction	registers `ctx.directoryPicker`
`directory-picker-browse/`	In-app directory-browser backend and interaction	registers `ctx.directoryPicker`
`directory-picker-auto/`	Host-adaptive picker composition	mounts a backend
`plugin-inventory/`	Read-only projection of current Loader entries	Remote `pluginInventory/list`

apiproxy remains transport-independent; client/connection supplies the browser/HTTP carrier. Picker implementations replace one another behind the shared seam.

The subsystem references: web-server.md and workspace.md (the picker seam).
