Reads ryzen7-cpu, ryzen7-ram and ryzen7-disk (43, 44, 45) once a second, and writes their maximum to ryzen7-load-index (54) as an indicator of how loaded the host is. All three inputs are percentages on the same scale, so the maximum is meaningful without normalisation.

ryzen7-load-index is an i7state state_signal with a timeout, so it reads NaN when the job stops writing. A stale value is therefore impossible: if the number is there, the job is alive. When an input is missing or not yet reporting, the script skips the write rather than writing a value derived from partial data, which lets the signal time out honestly.

Runs in docker.izazpi.cloud/infra/infra-python:0.1.12, which carries the i7lib wheel. There is no library folder on the host — i7lib reaches the script only through the image, so a new i7lib version means a new image tag here.
