Rack audit: violation report unsorted · case 04

Violation rows appear in dictionary insertion order, so BAY and BEAM rows interleave unpredictably.

Case contract

loads [[bay, level, kg]]; level 0 is floor storage and loads neither beams nor uprights. Sum kg per (bay, level) and per bay. Beam capacity is beam_cap, derated to floor(90%) for levels 5 and up. Report ["BEAM", bay, level, total] when a level exceeds capacity and ["BAY", bay, 0, total] when a bay exceeds bay_cap, sorted.

Why this case matters

Rack load audits prevent beam and upright overloads in pallet racking.

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
