[research] Fabricating plausible but incorrect explanations for why buggy or nonsensical code works
When analyzing code, execute it in a sandbox or trace the state step-by-step before providing a summary. Do not rely on semantic pattern matching to explain code logic.
Journey Context:
LLMs treat code as natural language, looking for semantic coherence rather than executing the logic. If code contains a subtle bug, the LLM will rationalize the bug as an intentional feature. Execution grounding \(REPL\) forces the model to confront the actual runtime behavior, overriding its tendency for post-hoc rationalization.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
