A run stops at whichever comes first, the step budget or --duration, so
a clean run that reached the wall clock exited with fewer steps than the
budget and was still credited with the whole of it. The model arm pays a
network call and a screenshot per step, so it reaches the wall sooner and
was handed exposure it never had.
Nothing checked that two arms shared a budget either. Thirty identical
clean runs under budgets of 400 and 100 read a12 0.000 and p 1.685e-14
from the rank-sum while the log-rank in the same report read p 1.0000.
groupArms already refused this within one arm.
The claims the old convention left in comments and report lines are
corrected rather than left standing beside the new behaviour.
--paired contrasts two arms running the same seeds seed by seed with the wilcoxon signed-rank test rather than treating them as two independent samples, reporting the per-seed differences, the sign, a12 within pairs and the seeds usable in one arm only. --question names the family holm corrected within, and the family size is recorded next to the p-values rather than left to the reader to reconstruct.
