Floor-pressure finding cites a per-compartment index · case 05

Load controllers are pointed at the wrong manifest line for over-pressure pieces.

Case contract

Input {'compartments':{name:[max lb, area sqft, max lb/sqft]},'pieces':[[compartment, lb, footprint sqft]]}. Per piece in order: unknown compartment -> 'UNKNOWN:i'; footprint <= 0 -> 'FOOTPRINT:i'; both exclude the piece from totals. Piece weight/footprint above the floor limit -> 'PSF:c:i' (piece still loaded). Then per compartment in sorted order, total above max -> 'OVER:c'. i is the zero-based index in the whole piece list.

Why this case matters

Hold loading is limited both by total compartment weight and by floor bearing pressure under each individual piece.

One recorded failure

Sample boundary fixture

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