First 63 days, minmax scaling
match ← All flat growth benchmarksThe 96-day mixed-feature history cut to its first 63 days: the training window of one cross-validation fold.
Input
benchmark/inputs/v1/flat-mixed-components-prefix-63.json: 63 history rows and 7 forecast rows.
Output
Largest difference: 2.0e-7 (< 0.0001% of the input's range).
Every forecast row from both libraries.
