# Concurrency is resolved at run creation, before the job `if:` is evaluated, so
# a run that will skip (e.g. an ordinary PR comment) would otherwise cancel the
# real in-flight run. Runs that will not do any work get their own unique group
# (keyed on run_id) and cancel nothing; only runs that will actually execute
# share the per-PR group, so a new push still supersedes a stale wait.
# The predicate below mirrors the `coverage-report` job `if:` — keep them in sync.
