  "why": "One measured cell of the committed breadth grid (reorder_bytes_max of packet_spray on clos_2tier/incast/16/0.0, the first data row) is doubled, so the wall-payer geomean is no longer 3886.0. The generator still exits 0 (it ends `return 0` unconditionally, audit A4 F7); repro.sh goes red because the printed geomean it parses differs from EXPECTED.md. It is the lab's own planted defect for this id (top40.json `defect_demonstration`)."
