The host-side coolant and fan tools call the ssh on PATH, or the client named by GF_SSH (a wrapper such as a WSL distro's ssh), instead of a fixed wrapper. The bench README lists every committed tool and data file, and explains how the coolant-flow fire-gate threshold was derived from the committed flow-matrix data and how to re-run that derivation on another machine.
