        # — no in-repo gate.) Keep this status informational so Codecov
        # measurement noise — carryforward flags, sharded/partial uploads —
        # can't fail PRs that don't change source (e.g. a dependency bump
        # reporting a spurious -0.01%). codecov/project is not a required check.
