Size classes: girth not doubled · case 01

Parcels far above the oversize threshold are treated as standard.

ROOT CAUSE

Girth is the sum of the two shorter sides instead of twice that sum.

VERIFIED REPAIR

Girth is 2*(width + height).

Unsuccessful approach: Doubling only the second side still undercounts girth.

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.
