…theus docs Documents the new total time in queue histogram metric, which measures end-to-end queue duration from entry to exit across all phases. Useful for teams using batching, bisection testing, or pending failure modes where wait+test time alone understates total latency. Pairs with trunk-io/trunk2#3439.
