 ## Packaged profile resolution
 
-`dsh` initializes shipped profiles under the explicit home, composes their bundle patches, and loads bundled plugins from the executable's virtual filesystem. Because operating-system symlinks cannot enter that filesystem, packaged launches maintain small real ESM proxy packages under `$DSH_HOME/profiles/node_modules`. Each proxy mirrors explicit runtime exports, records the original package identity, and re-exports the virtual module URL. Built-in rows and external plugin peers therefore share one Cordis/module instance. Native shared libraries and Windows ConPTY addons are packaged with native addons, while ripgrep and the macOS PTY helper remain executable sidecars.
+`dsh` initializes shipped profiles under the explicit home, composes their bundle patches, and loads bundled plugins from the executable's virtual filesystem. Runtime resolution uses an in-memory generation instead of disk symlinks or proxy packages. Fallback imports use recorded declaring-package paths, including paths inside the executable's virtual filesystem, so built-in rows and external plugin peers share the bundled Cordis/module instance. Native shared libraries and Windows ConPTY addons are packaged with native addons, while ripgrep and the macOS PTY helper remain executable sidecars.
 
 The Python bootstrap resolves the Office kit from its adjacent directory so native helpers and URL Workers use real filesystem paths. The kit owns engine selection and validation; the Python bootstrap adds no runtime download or compilation.

 ## 打包后的 profile 解析
 
-`dsh` 在显式指定的主目录下初始化随附 profile、组合其 bundle patch，并从可执行程序的虚拟文件系统加载内置插件。操作系统符号链接无法进入该文件系统，因此打包运行会在 `$DSH_HOME/profiles/node_modules` 下维护小型真实 ESM 代理包。每个代理复现运行时的显式导出项、记录原包身份，并重新导出虚拟模块 URL。因此，内置配置项与外部插件 peer 会共享同一个 Cordis／模块实例。原生共享库与 Windows ConPTY addon 会同其他原生 addon 一起打包；ripgrep 与 macOS PTY helper 仍是可执行伴随程序。
