 Even if all three environments share one RabbitMQ instance, they are fully isolated. A message published to `prod` cannot be consumed by a `dev` consumer.
 
 This was the operational pattern in the Namaste homelab — one RabbitMQ instance, three vhosts, multiple concurrent dev sessions running without interfering with each other.

+## POC Verification
+
+Current proof-of-concept verification for the two active appServer brokers is covered by integration tests:
+
+- `tests/broker_pool_test.rs` validates that configured rBroker/wBroker pool instances spawn.
+- `tests/broker_message_flow_test.rs` validates end-to-end message flow by publishing `ping` events to
+    `rec.read` and `rec.write` and asserting broker replies.
+
+These tests provide a lightweight deployment confidence check while the framework is still in the
+"POC before guardrails" phase.
