Dm Image Probe

Probe whether a decisions-model judge reads image input.

A decisions model accepts any state, so a call that merely succeeds proves nothing. The probe instead asks the judge the color of solid-color squares and trusts it only when it names every one.

clear_cache()

Forget every cached probe verdict.
