[research] Generating plausible but incorrect explanations of code logic or execution flow

Require execution traces or symbolic execution for verification before explaining behavior; explicitly state 'Without executing, the behavior is X, but edge cases might exist' if execution is unavailable.

Journey Context:
LLMs suffer from 'reverse execution' hallucinations—they predict what \*should\* happen based on semantic priors rather than strictly tracing syntax. This is a known failure in code reasoning benchmarks where models confidently explain a logic path that doesn't exist, especially with edge cases like off-by-one errors or mutation.
