Uniform exponential decay below one-half for circle packings

Let ES,p(s0,r)E_{\mathcal{S},p}(s_0,r) be the event that s0s_0 is connected to distance rr by open disks in site percolation with parameter pp. Uniform exponential decay conjecture. There exists a function f:(0,1/2)(0,)f:(0,1/2)\to(0,\infty) such that, for every 0<p<1/20<p<1/2, every circle packing S\mathcal{S}, and every s0Ss_0\in\mathcal{S} with

D:=supsSdiam(s)<,D:=\sup_{s\in\mathcal{S}}\operatorname{diam}(s)<\infty,

for every r>0r>0,

P(ES,p(s0,r))exp(f(p)rD).\mathbb{P}(E_{\mathcal{S},p}(s_0,r))\leq \exp\left(-f(p)\frac{r}{D}\right).

This is conjectured as the subcritical counterpart to the critical one-half conjecture and would provide decay uniform over circle packings with bounded disk diameters. The source does not state a resolution.
