Use the reviewed server-only selector in the existing-installation menu and bind automatic selection to available channel rows. A current selected release is a no-op; unavailable metadata or an automatic downgrade stops before mutations. Preview selection retains its channel, numeric beta/RC revisions compare correctly, and deliberate reinstall pins the actual current version.
Execute the actual menu through confined offline transport and stopped mutation boundaries. Preserve explicit version, interactive removal, signature and all-unit quiescence contracts; reconcile the inherited comment-only preview assertion with the real selector consumer.
