Budget rule received from the coordinator at the restart: the per-warp scratch is capped so the whole working set (1 GiB table + hot table + scratch for every resident warp + buffers) stays under 6 GB on an 8 GB card, which puts the scratch in the tens of KB per warp; the layer 5 hot table shares that budget.
