Honeycombing: negative net quantity sized · case 04

A SKU whose adjustments net below zero produces phantom loss.

Case contract

skus [[sku, pallets]] where lines may be adjustments (negative) and are netted per SKU. Each SKU with net pallets > 0 needs ceil(pallets/depth) single-SKU lanes. Honeycomb loss = lanes*depth - pallets. Utilization bp = floor((positions-loss)*10000/positions), 0 with no positions. Status OVER when lanes > available. Return [lanes, loss, util_bp, status].

Why this case matters

Deep-lane storage loses positions when lanes cannot be mixed across SKUs.
