Validation boundary

Forecast accuracy and inventory performance are reported separately.

  • Chronological holdout demand is shared across both policies.
  • Supplier profiles and lead-time seeds stay fixed for the comparison.
  • The values shown here come from the representative UI fixture, not a completed full-source run.
  • Median recommendation stability across fixed lead-time seeds is 80%.
