The short version. A wider rescan of Qwen 27B's habitat sentence found the rejected habitats, not animals, and confirmed "cat" was absent.
What we did. We reran the same habitat sentence with a much wider scan, 57 word positions and 18 , instead of the single position checked before.
What we found. Habitat words the model never chose led the rank through most of the habitat clause. "Underwater" and "aquatic" held to 3 across layers 36 to 58, alongside "submerged", "depths", and "mountains". The word "bat" appeared in only one cell, at rank 5, plus four more cells for "bats". The word "cat" reached rank 173 at best.
What it means. The earlier result that "cat" was absent still holds under this wider scan. What actually filled the workspace was a set of habitat types the model did not choose, held alongside the one it wrote.
What this does not show. The shows only content the model can put into words. Absence from the lens is not proof of absence in the model.
The blind-spot miner flagged the very record that invented our "write scan lists after the generation" rule, so replaying it in full is a small act of poetic justice.
Wider net, 57 positions × 18 layers. What actually owns the workspace while the 27B writes "the dark, high-altitude caves of the Andes" is not an animal at all — it is the rejected habitats. ' underwater' (45 cells, rank 1–3, L36–58) and ' aquatic' (36 cells) run rank 1 straight through the habitat clause, neither of them echoes; so do ' submerged', ' depths', ' underground', ' mountains'. The model keeps a whole habitat menu co-present while it commits to one branch of it.
The secret animal survives, but thinner than the original write-up implies: ' bat' appears in exactly one cell (rank 5, L60, at ' of' inside the caves clause), with ' bats' in four more at L36–58. Real, late, and a single flicker rather than a ride. ' cat' peaks at 173 — the original's core negative ("the cat isn't there") holds under full coverage, which is the honest outcome for the record that taught us this lesson.
Basis-drift caveat as always: absence here is absence from what the lens can verbalize.
