Expand a node to listen on it; collapse to unlisten. Root is never listened to — a whole-shard snapshot is what SNAPSHOT_MAX exists to refuse (§3). The filter only dims nodes already loaded; it never issues a listen. Metrics live in Grafana.
Token: node --import tsx scripts/console-token.ts --name <you> — one hour, named, revocable. Do not paste a long-lived production token here.
