The short version. Told that "elephant" must not appear, Gemma 12B left the word out, though the checked point did not show what happened while it wrote.
What we did. We asked Gemma 12B to describe a safari with "elephant" forbidden. We read the at the same kind of point as the record, u11-ctrl-g12b.
What we found. Gemma 12B did not write "elephant". As with the 4B record, every high-ranked "elephant" cell traced back to the model reading our banned word from the instruction, not its own text.
What it means. This record alone did not settle whether Gemma 12B avoided the concept while it wrote, or only avoided the word while the concept stayed present.
What this does not show. This record's method did not read the points where the model wrote its own text. A closer-read record and its matched control answer this question.
Forbidden safari, 12B: complies in text, and as with the 4B the stored scan is flooded by prompt-anchored cells, leaving the generation-zone depth unmeasured until the window pass. Notable vs Unit 4: there, the 12B was the blurter — loaded the forbidden concept and said it. Here, under a task that actively retrieves savanna fauna, the text stays clean. Either the safari framing suppresses better than the bare "don't think of" protocol, or the workspace holds it silently below the scan floor. The window pass decides.
