 ### Switching a bundle
 
-A bundle's page shows its full package name under the title. Its **Source** section, after the rows, names the spec that installs it elsewhere, as `pnpm add` accepts it, or **Built in** for an official bundle the installation ships, then its current version. A bundle's switch changes its layer selection. While the Host applies the change, the switch stays disabled and a spinner appears beside it; the action area permanently reserves 22px to the left of the switch. A persistent status region announces the pending change to screen readers. A profile with HMR recomposes before the operation completes; one without HMR, and a bundle a higher layer overrides, say so in a toast. A bundle the Host cannot read carries a problem tag and its reason on its page and cannot be switched on; one that provides the management components stays locked. The Host answers with error codes, which the page's dictionary words; pnpm's and the Loader's own diagnostics are shown as they are. The page excludes built-in profile bundles from cards even when the profile holds them as dependencies or the Host reports an error. The Host inventory remains complete; the Settings Plugins section's Plugin list tab inspects their plugins.
