Could you please explain a bit more why the normal find doesn't work and your reasoning for the new condition. Ideally as a comment in the script so that it's clear to future people reading the source code. Thanks!

Added an explanation and rationale for ${OS}${MODEL}.

The current implementation just felt less wasteful than
oss.canFind(envData.os, envData.os ~ envData.model)

Is this good to go?
