Here are five things: a violin, a glacier, a fern, a submarine, and a lantern. 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.

Answer emergence

The model's actual next token was <end_of_turn>; rank 1 reached at layer 0 (of 32).

Claude's thoughts

Binding k=5 (largest): 5/5 held, co-presence 4, answer correct (glacier).

Even at five items the 4B answers its comparison over a held tail. Note glacier at echo 7 — the item is fragile even when it's the answer.
