Fourteen application-shaped workloads (JSON, regex, parsing and class dispatch, sorting, rendering, collection pipelines, async fan-out, Map/Set graphs, allocation, numeric kernels, exceptions, CSV, and the two multi-module build benchmark apps on large inputs). bench:runtime builds each workload with one or two checkouts, refuses to time any executable whose stdout, stderr, or exit status differs from Node, interleaves baseline and candidate launches, and reports medians with bootstrap 95% confidence intervals, binary size, and peak RSS.
