\caption{Sampling-strategy baselines. All three adapters are trained with identical QLoRA hyperparameters on the same underlying problem set; the only difference is which problems are drawn. Accuracy in \%; 95\% bootstrap CI in brackets; $p$-value from paired bootstrap against the quantized baseline.}
