# The native_sim ztest suites are the only pre-hardware proof tier in this
# repo. Until this workflow existed they were run by hand, which meant
# "sim-green" decayed silently -- the suites were at one point unbuildable
# for weeks with no signal, because the break was invisible from the
# hardware side where the code is normally compiled.
