Why this formula appears here
This model has an explicit conservation ceiling built in: it cannot be extended past the compass’s own total intrinsic Fisher information = 4/ , since no amount of radiation can reveal more about g than the original state ever carried. A tolerance tighter than 1/ is not a slower recovery — it is a request for better precision than the compass itself possessed, which no observer, inside or outside any horizon, could ever meet. Within that ceiling, grows toward the hole’s full evaporation lifetime as is tightened, which is a specific, checkable form of the “information remnant” Nakata, Wakakuwa, and Koashi found…
