**Issue Evaluation** Category: `bug` | Status: **Confirmed** This is a valid bug in TimelineRollService. The issue correctly identifies that the service may repeatedly roll the same timer messages, leading to duplicate processing. **Root Cause:** The roll logic does not properly track which messages have already been rolled in the current cycle. **Impact:** Timer messages may be delivered multiple times, violating the at-most-once delivery guarantee for scheduled messages. **Severity:** High - affects message delivery correctness for timer/scheduled messages. **Assessment:** The fix should ensure proper tracking of rolled messages to prevent duplicate processing. 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.
