hub/apps/matrix reads apps/list and each app's config on every server (the read token first, the admin token once if a server refuses) and returns per app and server the version, available update and a config hash, plus whether versions and configs match and how many JSON leaf paths differ. Config texts never leave the hub. In hub mode the Apps section has the server selector: All servers shows the matrix with filters for differing versions, differing configs and updates; one server shows its list without write actions. The dev mock takes --variant a|b with differing apps. Co-Authored-By: Claude Opus 5.5 <[email protected]>
