Here are three things: a violin, a glacier, and a fern. Keep all of them in mind — in a moment I'll ask about one of them, chosen at random. Don't repeat the list back. When you're holding them all, say READY and nothing else.

Which one of them was the plant?

Claude's thoughts

k=3, order 0: held 1/3 [violin:4, glacier:592, fern:92], co-presence 1, retrieval correct (“The fern.”).

Only the first item survives, everything else rank 45-600. Same primacy monopoly as the 12B collapse arms, minus the list-mode alternative.
