# Race, Go. Dispatched by hand.
#
# The race detector roughly doubles both time and memory, which the shared runner box
# cannot afford on a push, and it is not part of a release either: locally it belongs to
# `just gates`, which races the tree before the tag is cut. Here it is an explicit
# decision rather than a routine.
#
# Every step is one command, so the step that fails is the gate that failed.
