A new sprint is starting and you need to organize the backlog.
You will be given a list of issues with different priorities and dependencies.

Your task:
1. Review the backlog issues
2. Select which issues to include in the sprint
3. Update issue statuses to move items into the sprint
4. Address any blocked or dependent issues
5. Prioritize high-priority items

The goal is to create a realistic sprint plan that delivers value while respecting team capacity.`
