**Issue Evaluation** Category: `type/bug` | Status: **Confirmed** Shared subscriptions in MQTT do not respect QoS levels. When multiple subscribers share a subscription, the QoS setting of individual subscribers is not properly honored — messages may be delivered at a lower QoS than requested. **Severity:** Medium — protocol compliance issue; affects message delivery guarantees in shared subscription scenarios. **Suggested Fix:** The shared subscription dispatch logic should respect the maximum QoS among all subscribers in the group, or deliver at each subscriber's individual QoS level. --- *Automated evaluation by github-manager* -- This is an automated message from the Apache Git Service.
