Case contract

items [[id, volume, kg, fragile]]. Sort by volume desc, kg desc, id. Place each in the first open tote (creation order) where volume and weight stay within limits (inclusive) and no fragile item shares a tote with an item over 10 kg (either direction). Items exceeding a tote alone go to oversize. Return [list of tote id lists, sorted oversize ids].

Why this case matters

Packing picked units into conveyor totes is bounded by volume, weight, and damage rules.
