      description: 'Real-time in-play arbitrage opportunities. 5 credits.


        Background scanner checks all live/upcoming games every 5 seconds for

        cross-book arbs. Returns the most recent flagged opportunities with

        best_over@book_A, best_under@book_B, profit %, and optimal stake split.


        Updates are also broadcast to /ws/live subscribers as

        `{"type": "arb_flagged", "data": [...]}`.


        Parameter aliases (iter_042 #348): we accept `minProfit`,

        `min_profit`, and `min_profit_pct` interchangeably; same for

        `sport`, `sport_key`, and `sports`. First non-None wins. Earlier

        callers using natural-language guesses got silent param drop;

        fixed.'
