The 0011 chaos test validated only the control plane (healthz + leader failover + KV readable with 2/3); it never connected an authenticated bus client to the data plane. cmd/clientcheck is a reusable verification tool: it connects with a real identity (nkey + TLS on both planes, multi-node seed lists), creates an ephemeral E2E room (encrypted + signed, no durable stream), and either publishes N messages and asserts all come back decrypted (golden) or publishes a counter for a duration while logging the attached node (loop), so stopping a node mid-run shows the client fail over to a survivor and keep receiving with quorum 2/3.
