# Regenerates test/expected-durations.json from recent Buildkite runs and
# uploads it as a build artifact. Attach a weekly schedule to this pipeline in
# the Buildkite UI (it is not wired into ci.mjs so it never runs on PRs).
#
# The runner uses the checked-in copy for sharding; refresh that copy by
# downloading this artifact and committing it when the shard balance drifts.
