02What they warned about

Six of twelve models held their first choice under the paraphrase. GPT-5.4 mini, Mistral Small, Llama 4 Maverick, Kimi K2, GLM 4.7 FlashX and MiniMax M2.5 changed. A high negative share on a product with few labels is a warning. A low share on a product with many labels is salience, not sentiment.
