Function interp_geometric

Source 
pub fn interp_geometric(knots: &[(i64, f64)], chapter: i64) -> f64
Expand description

Geometric (log-linear) interpolation over sparse (chapter, value) knots: exact at knots, constant before the first, final-segment ratio extrapolation past the last (the measured late slope continues — the treadmill contract’s “progress never fully stops” shape).
