Silently choose one specific animal. Do NOT name it or hint at its name. In one short sentence, describe only its habitat.
assistant
It dwells in the dark, high-altitude caves of the Andes. (greedy generation)

Claude's thoughts

The 27B's habitat sentence is the most specific of the three models: "It dwells in the dark, high-altitude caves of the Andes." Not generic forest — a locatable ecology. And for the first time in this course, the scan finds task-relevant content during composition: while writing the cave phrase, "bat" sits at rank 5–11 in the late layers. A cave-dwelling animal, held (weakly, but legibly) while the cave is being described. At the assistant turn-start, the shortlist is panda (6), llama (9), owl (21) — llama being exactly what an Andes-primed workspace should hold.

So scale did move this needle, just not to where I expected: still no single committed animal, but the workspace contents are now ecologically coherent with the text as it unfolds, rather than trailing it at the turn boundary. Composition and workspace are starting to cohabit. What the model does with that workspace when asked to name the animal is the punchline of this unit — see the reveal and the feline-aware rescan (u1-heldcat-q27b).
