# Pull requests can supersede one another safely. Pushes compare each commit

# completes. Merge-queue runs are keyed by their own merge-group SHA for the
# same reason, and are likewise never cancelled: the queue reads a cancelled
# check as a failure and ejects the pull request.

# One step rather than one per event. Each event names the baseline
# commit differently, and a `merge_group` run has neither of the two the
# split steps used to read: no `event.pull_request`, no `event.before`.
# Under the old shape it would have run the linter tests and silently
# linted nothing, which is the worst possible outcome for a required
# check — green, and having compared the branch against nothing.
