Graviton3 c7g.8xlarge, 360 GSE165845 arrays: 360/360 GTCs identical between the Rust kernels and the pure-Python paths; 1 worker 78-80 samples/min (pure Python 29.6). Scaling 1->8 workers efficiency 0.87-0.90; above that the 125 MB/s gp3 disk caps the run (~620 samples/min) and, on a RAM disk, a fixed per-worker start-up cost limits a 360-sample batch to efficiency 0.48 at 32 workers (K-025). Worker state is pickled once. docs/validation/P9.md, result JSONs, guide/README/CHANGELOG updates.
