**Issue Evaluation** Category: `bug` | Status: **Confirmed** The reported index misalignment in `PopConsumerService` has been verified against the current `develop` branch. **Root Cause:** In `PopConsumerService.java` (line ~434-436), the loop iterates `getMessageResultList` by index `i` and looks up `popConsumerRecordList.get(i)` with the same index. When a single fetch result contains multiple messages, the record list has one entry per message while the result list has one entry per fetch — so after a multi-message batch, index `i` points into the wrong batch. **Impact:** With `popResponseReturnActualRetryTopic` enabled, a retry result can be misidentified as normal and skip retry-message recoding, leading to incorrect message routing. **Severity:** High — affects POP consumption correctness under multi-message batch scenarios. **Verified at:** `broker/src/main/java/org/apache/rocketmq/broker/pop/PopConsumerService.java:434-446` An automated fix proposal can be generated.
