# noswap.sh MINUTES — night 2026-10-21 Part 2.1: does the freeze come back on a host with NO swap? On the soak VM
# (host 192.168.0.128, NOT demo-hp): record → `swapoff -a` → the same upload burst (load2.py cycles on the helper CT 9332,
# via noswaprun.sh) for MINUTES → `swapon -a` → record. The 10 s recorder and the outside probe keep running.
# Run from DooPlex. Prints a timeline; nothing secret.
