Flat vs weight: box dims not rotated · case 01

Items that fit a flat box on their side are told the box is too small.

Verified by executionVariant 1 · 8 checks per implementationDownload source bundle ↓JSON ↗

ROOT CAUSE

Box inner dimensions are compared in catalogue order against sorted item dims.

VERIFIED REPAIR

Sort both item and box dimensions before comparing.

Unsuccessful approach: Leaving item dims unsorted still depends on how the item was measured.

Case contract

boxes [[name, L, W, H, price]] inner dims; an item fits a flat box in any orientation and flat boxes accept up to 70 lb. Weight price = weight_rates[lb-1] with lb = ceil(weight) (min 1) when lb is within the table. Choose the cheapest option; on equal price prefer flat boxes, then name. Return [option, price] or ["NONE", 0].

Why this case matters

Shippers compare flat-rate packaging with zone weight pricing.

Verification & scope

Single zone weight table; stipulated flat box catalogue. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.

Observations recorded using Python 3.12.14 at 2026-09-29T14:52:15.422121+00:00.
