The pipeline was observable from a merge to an artifact and went dark where it touched a machine: a node's report is control traffic only the control plane reads, so nothing said which version a machine runs, or that it refused to (novox/hq ADR 0134). The control plane now states both under the seat it holds — a role's events belong to the role and keep their address when the holder is replaced — and only when the report is news, because a machine reconciles every minute and a fact per report would be a fact per minute per machine. Whether a report is news is the store's answer: it holds the previous one, so the listener returns it and the server states the fact. That also gives the catch-up replay a subject the controller may publish: it was published as a module's event from a module called "control-plane", which does not exist, so the controller's own account refused it and every catalogue that asked what it missed was answered with nothing.
