**Issue Evaluation** Category: `bug` | Status: **Confirmed** The reported issue has been verified against the current codebase (develop branch, commit 7eee0fc366). **Root Cause:** `SendMessageActivity.SendMessageQueueSelector` only reads `messageGroup` when `request.getMessagesCount() == 1`. For FIFO batch requests with multiple messages, the sharding key remains null and falls back to `selectOneByPipeline(false)`, breaking FIFO ordering guarantees. **Impact:** Proxy gRPC producer path, FIFO message ordering for batch sends **Severity:** High — violates FIFO semantic contract **Code Location:** `proxy/src/main/java/org/apache/rocketmq/proxy/grpc/v2/producer/SendMessageActivity.java` lines in `SendMessageQueueSelector.select()` The proposed scope is well-defined and addresses the root cause. An automated fix proposal can be generated. Reply `/approve` to proceed with PR generation. --- *Automated evaluation by RockteMQ-AI* -- This is an automated message from the Apache Git Service.
