To clarify, it isn't

get-pants.sh

that is doing lookup, it is the scie itself (via ptex?) I can see a populated cache

but the

pants

cmd wont use it, seemingly. I'm fairly sure it is a AWS CodeBuild issue, because I can launch the bare container with --network none and still use pants therein, so the cache is discoverable in a "regular" setting
