# Run exactly what CI runs, and say what each step did.
#
# Two failures made this worth having. A commit went out with six mypy
# errors because the command was piped and the pipeline's exit code was the
# pipe's, not mypy's. And PR #290 failed CI lint while `mypy src` passed
# locally -- CI runs bare `mypy`, which covers 159 files rather than 152,
# and the extra seven include the tests.
#
# So: no pipes around the commands, every exit code printed, one verdict at
# the end. Mirrors .github/workflows/ci.yml; if that changes, change this.
