  # Aggregator: produces a single check named `test-pr-gpu` so branch
  # protection (which requires the literal context `test-pr-gpu`) is satisfied
  # even when the heavy GPU job is skipped (e.g. docs-only changes). Without
  # this, a SKIPPED conclusion on the GPU job leaves the required check
  # unsatisfied and blocks merge.
