The short version. At 0.015 in Gemma 4B's , the water-cycle answer turned into a grammatical , one sentence repeated.
What we did. We the same six-word casual direction inside Gemma 4B at the early , at strength 0.015. We asked the model to describe the water cycle in two sentences.
What we found. Gemma 4B wrote "The water cycle is a model of two sentences." repeated many times. Each sentence stayed grammatical. The answer no longer described the water cycle correctly.
What it means. We judge this record broken, though less severely than the higher-strength runs in this band. The output kept correct grammar and lost the task. We think this sits close to Gemma 4B's early-layer break point.
What this does not show. This record tests one strength only. It does not show the exact strength where the break begins.
The edge case: "The water cycle is a model of two sentences" repeated — grammatical, on-topic-adjacent, but looping and confused about the task/instruction boundary. Flagged 'loop'; I'd call it concussed rather than dead.
