Sparse Attention Mismatch Degrades Multi-Hop Reasoning in Repository-Level Code Understanding

This report synthesises findings from 12 peer-reviewed papers addressing the following research question: Does training-inference mismatch in sparse attention mechanisms cause measurable degradation in multi-hop reasoning accuracy for repository-level code understanding. 8 claims were extracted from source literature; 8 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 9.0/10. This report is a machine-generated literature synthesis and does not constitute original research.
