  "notes":"No UN candidate is claimed. The downloaded IB artifact is a frozen 19-input policy; its params input_count is 19 and its new_input_formulas are raw_amountY, step_trade_count, prev_bid_fee/prev_ask_fee, steps_since_arb_like_print, and router_implied_vanilla_spot. The downloaded FA artifact instead has a different 19-input order with T_bid_fee, T_ask_fee, prev fees, (spot-pHat)/pHat, and retail_flow_rate. Combining these into the requested 23-input policy requires implementation and fresh gate/search/real-engine measurements, which are not available here.",
