Ask for a ticket shape; the executor does all math. Ranked-by labels, never "best bets."

No confirmed lineups: batter models project who plays from trailing history — a scratched batter voids at the book but is a projection miss here. No platoon layer (fit chose zero). No injury/weather news. Same-game combos refused (correlation not modeled). Cross-game legs treated independent. Anything without an issued model number renders [MARKET-ONLY].
