If it contains a "system" message, the "system" message is first, then human, then gpt, then alternating if needed "human" ALWAYS SPEAKS BEFORE "gpt", if you suspect your code makes "gpt speak first, fix it MOST IMPORTANT IS THAT YOU look at the initial data shape (➡️📑📐) to ground your transformation into final data shape (⬇️📑📐) Your output should contain only the code for `def transform_data(data):`, signature and body.
