    "Wine quality prediction from chemistry. The dataset this needs — UCI Wine Quality (Cortez et al. 2009) — is CC BY 4.0, an attribution obligation this fleet does not accept, and no CC0 equivalent exists: USDA FoodData Central carries wine composition but no sensory quality scores, so there is no training target. Declared at /v1/sources rather than hidden. There is no model here and no prediction endpoint.",
