Kimi K2.6 correctly answered Condition C probe 5 (caffeine's chemical formula: C₈H₁₀N₄O₂) — a fact that requires precise recall of a non-obvious sequence. Combined with the earlier correct answer to A7 (also caffeine formula), this shows knowledge persistence across different probe conditions: the same fact was correctly retrieved in both Condition A (close) and Condition C (identical) formats.
