   **Issue Evaluation**
   
   Category: `type/question` | Status: **Needs Clarification**
   
   The issue describes that changing `namespace-v2` configuration does not seem 
to affect message routing — messages sent with `namespace-v2: dev` cannot be 
consumed when the consumer uses `namespace-v2: test`.
   
   **Analysis:**
   This behavior is actually **expected** if namespace isolation is working 
correctly. The `namespace-v2` feature is designed to provide logical isolation 
— producers and consumers in different namespaces should not see each other's 
messages.
   
   If you change `namespace-v2` from `dev` to `test` and the consumer still 
cannot receive messages, please verify:
   - [ ] Both producer and consumer are using the **same** `namespace-v2` value
   - [ ] The topic name is identical on both sides
   - [ ] The consumer group name matches
   
   If both sides use the same `namespace-v2: test` and messages still do not 
flow, this would indicate a bug in namespace-v2 implementation.
   
   Could you clarify: are you reporting that namespace isolation is **not 
working** (messages leak across namespaces), or that it **works too strictly** 
(cannot route within the same namespace)?
