What changes when one material enters two garments?
The record may be the same. The questions change with the cut.

170 gsm is a record, not an answer.
S01 and S03 currently share a candidate record of 70% viscose, 30% linen and 170 gsm. The number stays the same; the questions change with the cut.
The jacket asks about the shoulder; the skirt asks about the hem.
In the jacket, the sample must answer whether the shoulder sits too hard and where folds appear in movement. In the six-panel skirt, show-through, waistband recovery and hem movement remain open. The number informs selection; it cannot judge the finished garment.
