- gpu: the test modules share one GPU_LOCK, and timing and vector_mask take it too, so one process drives one wgpu device at a time. - ui-egui: the wgpu tests in pattern_preview_canvas, adjust_preview_gpu, marquee_autoscroll and layout_perf take gpu_lock(). - affinity compound_limits: the child process selects its test by the module path (compound_limits::<name>); with --exact, the bare name matches no test and the child passes without running the check. - xtask scorecard reads crates/io/tests/it/corpus.rs. - Docs and comments name the new test paths and the --test it filters.
