So there's this thing called "Setup Scripts" but they don't explicitly say these are equivalent to AWS Metadata and configured inside of Codex web interface - not a setup.sh or a package.json preinstall declaration. I wasted several hours (and lots of compute where Codex was as confused as I was) trying to figure out how to convince codex to pnpm install.
I didn't realize the setup script had to be done in the UI over in the environment tab. I assumed it would be reading something like setup.sh from the codebase.
