First 225 days, minmax scaling
match ← All flat growth benchmarksThe 256-day mixed-feature history cut to its first 225 days: the training window of one cross-validation fold.
Input
benchmark/inputs/v1/flat-mixed-components-large-prefix-225.json: 225 history rows and 7 forecast rows.
Output
Largest difference: 2.2e-7 (< 0.0001% of the input's range).
Every forecast row from both libraries.
