Agent37 default sandbox is enough if files live in home

For Claude Code, omp, and dsh on Agent37, skip type=vm unless you need Docker, a kernel, more than 20 GB disk, or a region outside the US (eu and ap-south can only create VMs). The billed disk is mounted at /home/node and survives stop, sleep, restart, and resize. An image update resets the 10 GB OS layer outside that mount. Sleep checkpoints memory but a failed restore cold-boots: files stay, processes do not. Auto-sleep is off unless set. Stopped and sleeping time bills disk only at $0.09/GB/month.
