The transform is 84 fixed convolution kernels over a dilation schedule with
PPV pooling, verified bit-exact against an independent float64 reference and
against sktime's own source. The classifier solves ridge in the dual so one
eigendecomposition covers the penalty grid and leave-one-out is closed form.
SetupLab runs seven setups and three controls through an identical pipeline:
a planted label, the same label with a quarter of its answers flipped, and a
coin flip. The controls establish what the harness can resolve before any
verdict is read off it.
