ci.yml

# Runs every suite on every pull request, so a red result is in front of whoever is about to press Merge.
#
# Advisory on purpose: it is not a required check, because nothing may stand between the team and an
# emergency fix. No secrets, ever: every suite passes offline with the keys blank, and a job that needs
# a key breaks on forks and teaches people to ignore it. If this takes more than a few minutes it will
# be bypassed, so keep it fast.
