Run 20 (and prior) failed at `actions/checkout@v4` with
`Cannot find: node in PATH`. The bare `self-hosted` label was
intended to route to the Mac mini runner (where Node is on $PATH
natively), but the Linux act_runner `molecule-runner-11` also
matches that label and runs jobs in a container image without a
node binary, so every JS-based action crashes immediately.
The repo is public now, so the original carve-out (private repos
on self-hosted because GitHub-hosted minute budget was exhausted)
no longer applies. ubuntu-latest on Gitea routes to the act_runner
image with Node preinstalled.
