[research] Failing to answer questions about the reverse relationship of a known fact \(Reversal Curse\)

When querying an LLM for bi-directional relationships, explicitly rephrase or provide context for both directions; never assume the model infers 'B is A' from 'A is B' training data.

Journey Context:
LLMs trained on 'A is B' do not automatically generalize to 'B is A' due to autoregressive left-to-right training. If an agent needs to traverse a graph of relationships \(like code dependencies or class hierarchies\) backwards, it will hallucinate or fail unless the context explicitly bridges the reversal.
