Reproduction steps:

docker run --rm -it --network host node:20.11.1 bash

mkdir -p /root/.cache/node/corepack
npm install -g corepack@0.25.1
corepack enable

git clone --depth=1 https://github.com/nodejs/corepack
cd corepack
yarn
yarn build
NOCK_ENV="replay" CI=true yarn test up

That doesn't make sense to me, I don't see how the global Corepack version would be relevant in this context 🤔

Note that it doesn't reproduce with the following:

docker run --rm -it --network host node:20.11.1 bash

mkdir -p /root/.cache/node/corepack
npm install -g corepack@0.25.1
alias yarn="corepack yarn"

git clone --depth=1 https://github.com/nodejs/corepack
cd corepack
yarn
yarn build
NOCK_ENV="replay" CI=true yarn test up
