A magit-style TUI for Linux system runtime ops, and one of meowr's guest applications. systemctl-tui manages units well; btop and htop monitor resources well; nothing does both, and nothing applies magit's actual organizing idea — a status buffer that shows what needs attention, rather than a dashboard that shows everything.

A healthy machine produces a nearly empty screen. An unhealthy one puts the problems under it, worst first — a failed unit, a pressure spike, a disk running low — each buffer answering one question: what's running and why (Procs), what the units are doing (systemd, over zbus), what the disks and filesystems are carrying (IO), and — on a host with a declarative platform adapter like NixOS — what the running system and its declared configuration disagree about (Nix). That last buffer doesn't exist at all on a machine with no declared configuration to compare against; there's nothing there for a digit to open.
