This records the lesson of the 2026-10-04 outage, when a full upgrade restarted a workstation's system bus and its logins hung.

node-message-bus becomes a node seat. The first holder is a dbus module.
The bus is never restarted or reloaded by the mesh. A new version waits for the next boot.
Only curated events go out: the bus's health, well-known system services coming and going, and policy denials. Its traffic never leaves the machine.
The seat receives nothing yet.

To-be 42 cites it. Checks: records.py and index.py pass. cycle.py passes for this record; it still flags ADR 0214 (backups), which already fails on main and isn't part of this PR.
