    "A fixed 8 October funding review, not the latest observation for every instrument.",
    "System funding evidence does not measure an individual institution's liquidity or probability of failure.",
    "A rate difference alone does not establish rising or falling stress; this brief makes no historical trend claim.",
    "Reserve balances are a weekly average for the week ended 7 October; other rows have separate source dates.",
    "Archive time begins at first verified capture. This is not complete historical publisher-vintage data.",
    "Publisher terms remain attached; chart and API availability do not grant blanket data redistribution rights."
