Initial-condition universality of the KPZ upper tail field

Let the KPZ fixed point have a general initial condition that grows sufficiently more slowly than $f(x)=x^2$ as $|x|$ becomes large, so that the KPZ fixed point exists at $(0,1)$. General-initial-condition upper-tail conjecture. Theorem 1 holds for the KPZ fixed point with such a general initial condition, and the upper tail field of the KPZ fixed point is independent of the initial condition. This is proposed as a generalization of the paper's main result beyond the narrow-wedge initial condition; the supplied text gives no resolution.
