How far apart can nearby starts become?
Release the two paths with the scatterer off. Reset, switch it on, and compare the separation trace.

About this tool
What you are looking at
Two paths start epsilon apart and move through a simulated square billiard. With the circular scatterer present, their sampled paths can separate and enter different coarse cells. The displayed rate is a finite-time divergence proxy, not a fitted Lyapunov exponent or an entropy measurement.
How to use it
Set the initial gap, compare Scatterer off and on, then select Release. Read separation in multiples of epsilon, the divergence proxy, the matched-or-lost state, and the log-separation plot against path length. Reset before starting another comparison.
