Size classes: first listed side taken as length · case 01

Girth is computed around the longest side when dims are not entered longest-first.

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

ROOT CAUSE

Dimensions are used in entry order instead of sorting the longest side first.

VERIFIED REPAIR

Sort dimensions descending; the longest is length.

Unsuccessful approach: Sorting ascending treats the shortest side as length.

Case contract

dims inches (any order), weight lb. length = longest side, girth = 2*(other two). UNSHIPPABLE if length > 108, length+girth > 165 or weight > 150. Otherwise OVERSIZE if length+girth > 130; else AHS_DIM if length > 48 or second-longest > 30. AHS_WEIGHT if weight > 50 (independent). Return list of codes.

Why this case matters

Size and weight classes decide handling fees and service eligibility.

Verification & scope

Stipulated thresholds; not a carrier service guide. 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.
