Entropy of the Limit Remnant: How Much Disorder Survives Evaporation

At the remnant mass of 8.659e+10 kilograms the entropy is 1.989e+38 in units of Boltzmann's constant, or 2.870e+38 bits. A hole one hundred times heavier carries 1.989e+42 in the same units, ten thousand times more, displaying the quadratic law. A stellar-mass progenitor exceeds the remnant's budget by nearly forty orders of magnitude, so a remnant that stores everything must do so in degrees of freedom that the horizon entropy does not count, an extra assumption that should be stated as such rather than smuggled in. The value of the calculation is that it separates two claims that are often blurred. Computed from stated assumptions, not measured.
