Stage-wise diagnostic comparison of L1-L4 metrics between incorrect and correct solutions (Table 5). The article reports "Correct solutions outperform incorrect solutions on all four process-level metrics"; printed deltas include +46.9 (MathCanvas-7B) and +53.5 (CodePlot-CoT-32B) for reasoning.

"Correct solutions outperform incorrect solutions on all four process-level metrics for both models."
