# The macOS leg of the gate: `cargo xtask ci` on Apple silicon, through the suite's shared gate
# workflow. The Linux gate (ci.yml) has no real GPU and runs on x86, so GPU tests on Metal and
# results that depend on the platform's math library first ran on a contributor's Mac.
#
# On pushes to main, not on every pull request: macOS runners are scarce. A newer push cancels the
# older run, so main is checked at its latest commit. Pull requests that change this file run it.
