Summarization quality is subjective at the margins, which makes it exactly the workload where judge-based scores need calibration receipts. The measured suite anchors judging against references and calibrates judges against tasks with deterministic truth, publishing the correlation rather than asking for trust.
These two are part of a larger measured frontier — what is the best model for summarization shows every measured option for this workload, and other workloads rank these models differently: a model that wins here can lose on another kind of work, which is the whole argument for routing per workload rather than picking one model for everything.
