    "Because the panel accrues daily, a later re-run over a longer window will not reproduce these exact numbers — reproduce against shards as of the panel window above, or expect the estimate to move within its CI.",
    "The measurement is an association, not a direction and not advice. The case-study dataset that once accompanied it was withdrawn (the dated retirement object rides https://signalbureau.ai/api/record-data) and is not part of this bundle."
