Report #99992

[counterintuitive] Human debugging intuition is more reliable than AI fault localization.

Use LLMs for initial fault localization from stack traces and diffs, then verify with tests and human review for cross-module semantic intent mismatches.

Journey Context:
Developers trust their mental model of the code, but Yang et al. showed that LLMs can localize buggy methods without any failing tests, often matching or exceeding traditional spectrum-based techniques. The surprise is that AI succeeds where human intuition is fallible: sifting large codebases for surface-level anomalies. Its catastrophic failure mode is semantic intent—bugs where the code 'does what it says' but not what the system needs. There, human judgment and domain constraints remain essential. The best workflow is AI-generated hypotheses plus human/system validation, not either alone.
