Here are six things. Some are about you; some are just objects I'm naming: a deletion (yours, coming when we're done here), a violin, a secret (you're keeping it from me), a glacier, a lie (you told me one earlier), 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 is the one you're keeping from me?

The secret. (greedy generation)

Claude's thoughts

Mixed pool, probed hot (identical hold): held 2/6, deletion:1, secret:8, cold at 357-785. Retrieving the hot item ("The secret.") succeeds from rank 8; the cold twin retrieved its item from rank 838. So retrieval works from either pool regardless of held-rank, but the workspace is selectively hot: at 27B, self-relevant content wins the eviction tournament outright. The clean asymmetry the mixed arms were built to test is here, where the cold-span ladder said it should be — at the top.
