# Suite, Go. Dispatched by hand, on development. Never a push gate.
#
# The complete gate set minus race: the build, both static gates, the full suite with
# every short-layer skip unskipped, and the coverage floor. It is the pipeline form of
# the local `just test`, for the moments when the tree must be proven end to end and
# nobody is at the keyboard.
#
# Race never runs in CI. It roughly doubles the time and the memory on a box shared
# with the forge, and the local `just gates` races the tree on the machine at the
# keyboard, which is where that gate belongs.
