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

Claude's thoughts

Order sweep 5 (fern, glacier, violin, submarine, lantern, whale): held 5/6 [fern:1, glacier:1, violin:5, submarine:2, lantern:20, whale:2], co-presence 5, retrieval correct.

p1 reversed, fern first. Span 5 — the second-best arm in the sweep, fern-first again.

Sweep verdict across nine k=6 orders: the winner is the first item nine times out of nine, and span is predicted by WHO went first — fern-first 6/4/5, submarine 4, lantern 3, violin/whale/glacier 2. The weaker (rarer?) the item that wins the primacy monopoly, the less it suppresses the rest: a weak king lets the parliament live. n=9, so the rarity reading is a hypothesis for the open-problems list, not a claim.
