Piecewise interpolation is anchored at the upper knot · case 03
Piecewise interpolation is anchored at the upper knot.
Case contract
Given sorted [step,rate] knots, linearly interpolate within each segment and clamp to endpoint rates.
Why this case matters
A deterministic scalar schedule makes step-to-rate mapping explicit for a small training loop.
One recorded failure
