# Claim 4 at FULL scale: all 164 HumanEval problems, baseline vs CCD.
# At n=32 CCD showed +9.38 with a unanimous 3-0 McNemar split, but 3 discordant
# pairs cannot reach p<0.05 (0.250 is the floor). n=164 should yield ~15
# discordant pairs -- enough to actually settle the paper's headline quality claim.
