--fetch also exported and stopped on the absent dist/truth before any
download, so CI skipped every exporter fidelity case and tolerated the
step. --refresh-cache only downloads: the step can no longer fail
unseen.
validate.yml runs export_native with continue-on-error, and pr_checks
failed the whole run on it. The step is now shown and does not fail
the run, and a test keeps that list equal to the workflow's.
validate.yml runs mypy against its baseline and checks that shellcheck
is installed, and pr_checks ran neither. The guard test only knew the
python, vermin and npm commands, so it missed both. A step can now pipe
its output into a second command, as mypy into mypy-baseline filter.
