Assumed bid construction, iid sampling, daily checks and frozen spreads are not venue executions or calibrated live odds. Does not create an additional permanent veto; BB already fails both payoff alternatives. Contrast forbidden hold-through counterfactual: training11 mean-$22.39 per ticket,2wins, not a traded backtest.
