+// A "human" peer (alice, a plain SDK client) sets up a connection and sends a
+// message to a coding agent (bob) that runs entirely through plugin-tinyplace with
+// the `mock` harness. The real per-agent daemon drains the relay, decrypts once

+// it in the outbox; the daemon encrypts + sends it back. Alice decrypts it.
