DairyDan milk yield models

History pathway (≥3 records) — scale-free autoregressive linear regression over the last 7 sessions (ts_linear_regression.joblib). Test MAPE 3.41% vs moving average 7.98% (monthly series, 1973–75).

Cold-start pathway (<3 records) — Keras MLP on the cow profile (coldstart_nn.keras + coldstart_preprocessor.joblib), anchored to Kenyan breed baselines (breed_baselines.json). Target: knowledge_informed. Test MAE 1.391 L/day vs breed lookup 8.624 L/day.
