As the number of open PRs grows, it becomes increasingly difficult for maintainers and reviewers to prioritize and manage them effectively. Key challenges include:

• No risk visibility: Reviewers cannot quickly identify which PRs are high-risk (e.g., touching interfaces, lacking test coverage, high blast radius) vs. safe low-risk changes.
• Hidden cross-PR conflicts: Multiple PRs may modify the same functions or share call paths, creating merge conflicts or semantic conflicts that are not obvious from individual PR reviews.
• No prioritization: Without structured risk signals, reviewers spend equal effort on trivial and critical PRs alike.
