\caption{Pre-registered uncertainty analysis of dev-iid exact match (percentage points). ``t-CI'' is the 95\,\%
$t$-interval over independent adapter seeds of the per-seed paired difference; ``item CI range'' spans the
smallest lower and largest upper bound of the per-seed paired item bootstraps (10,000 resamples, 1,000 items).}
