First 63 days, absmax scaling

match ← All flat growth benchmarks

The 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: 2.8e-7 (< 0.0001% of the input's range).

Every forecast row from both libraries.
