Duplicate analyses and uncertain within-point correlation are handled in separate sensitivity/bootstrap calculations. The fitted slope measures integrated decay; a radiometric age is not imposed as an independent clock. Right: a declared 4.56-Gyr record and 2-Gyr Oklo window illustrate temporal coverage only. Those dates do not independently constrain the changing-decay fit.",
