What the article says around this equation

Nt\mathcal N_t is the effective channel from A to R\!∪\cup\!CtC_t induced by the hole’s own scrambling dynamics up to time t ; ϵL(t)\epsilon_L(t) is a dimensionless number in [0,1] , and tLt_L has units of time. This is a yes-or-no-shaped promise sharpened into a number: either a decoder within ϵ\epsilon of perfect exists on the stated resources, or it does not, and ϵL(t)\epsilon_L(t) falls, in the regime this article works in, toward zero as t grows past a threshold.
