     * This was an unscoped Conversation::query(), so the sidebar and the search
     * modal on this page rendered other people's chat titles and linked to
     * their conversation ids. The scoping in ChatController exists precisely to
     * stop that, and the sidebar composer only fills the list when the page has
     * not supplied one - so supplying an unscoped list here actively defeated
     * it. ChatListIsScopedTest covers /chats, the dashboard and the chat page,
     * and did not cover this route.
     *
     * Participant-less rows are included for the same reason ChatController
     * includes them: they predate ownership being tracked and mayOpen() still
     * opens them, so hiding them here while the URL works is a different drift.
