# A new commit supersedes the previous one's jobs, so stop paying for them
# across the whole matrix below. Only pull request runs share a group; every
# other run gets a group of its own (`github.run_id`), because a group holds
# at most one pending run and a later push would otherwise evict the one
# waiting — `cancel-in-progress` protects the running run, not the queued one.
# The branches this also builds on push (`main`, `next`, `v4`) publish the
# coverage later comparisons are measured against, and losing one of those runs
# would also hide a breakage that is already on the branch.
