+**Added 2026-10-04.** Two more modules for every machine:
+- `power` holds `node-power` ([ADR 0211](../../02-DECISIONS/0211-a-machines-power-is-a-node-seat-its-moments-take-contributions-and-its-states-are-events.md)). Other modules contribute code for
+  its moments (after boot, before sleep, after waking, before shutdown, on mains, on battery), and it
+  publishes the machine's power states on the bus.
+- `dbus` holds the message bus. Modules shipping D-Bus policies or services contribute them to it.
+  It shares curated events, never raw traffic. An upgrade never restarts the bus live: its package
+  waits for a reboot. A live restart in the middle of a full upgrade took down a workstation's
+  logins on the day this was written.
