The tuned baseline achieved test MSE 0.02255185, while the best PAC configuration achieved 0.36016439; paired delta was +0.33761254 with permutation p=0.0081, yielding the required verdict idea worse (significant). The trained-model mechanism signature was not confirmed: held-out miss rate was 0.3017 versus epsilon 0.1.",
