    "classification": "hard",
    "classification_meaning": "a hard saving is a reduction evidenced in adjudicated paid claims against the prior period's run rate, expressed on a plan membership basis",
    "classification_reason": "the lower rate shows up on the claims that are actually paid, so the reduction is read off the run rate rather than modelled",

    "evidence_required": "adjudicated paid claims for the same code mix, before and after, incremental to the prior period's run rate and expressed on a plan membership basis",
    "is_not": "NOT a savings figure and NOT evidence that the declared mechanism operates: this payload classifies the mechanism the caller declared against this world's cited definitions and carries no number anywhere. Whether the mechanism delivers anything is settled by the evidence class named above, which this world does not hold.",

    "mechanism_meaning": "the same services are delivered and each unit is paid at a lower rate",
    "not_summed_note": "hard and soft are classified one mechanism at a time and never summed, because a claims-evidenced reduction added to a modelled counterfactual reports one number with two different evidence classes behind it.",
