[research] LLM fails to answer 'Who is X's mother?' when it only learned 'Y is X's mother'

When checking facts, do not assume bidirectional knowledge. If a reverse query fails, rephrase to the canonical forward direction or perform a retrieval step.

Journey Context:
LLMs suffer from the Reversal Curse—they do not automatically generalize 'A is B' to 'B is A'. An agent might confidently hallucinate an answer to a reverse query instead of recognizing it as a simple logical inversion of a known fact. Recognizing this architectural limitation prevents false negatives and unnecessary hallucinations by simply rephrasing the query.
