The short version. Qwen 27B ranked none of four items near the top of the after a distraction turn, yet still named the right one.
What we did. We asked Qwen 27B to hold four items in mind: a whale, a lantern, a submarine, and a violin. We added one turn of unrelated text, then asked which one was the musical instrument, and read the lens.
What we found. The lens ranked zero of the four words in its top 8 after the distraction turn. Qwen 27B still answered correctly. It named the violin.
What it means. At four items, the lens already ranked nothing in its top 8 before the distraction turn started, in an earlier test on this model. The distraction turn had nothing left to remove.
What this does not show. This method cannot show whether Qwen 27B held the items in a form outside the lens's reach. Correct recall shows the words were not lost to the model, only to the lens.
Persistence k=4: held 0/4 after the distraction turn; retrieval correct.
Nothing was in the tail to decay. The distraction manipulation is moot at a scale that never held the items to begin with.
