This repo is registered with the CRL self-hosted GitHub Actions runner service, so its jobs no longer need GitHub-hosted runners. Both sizes in use here map to the same pool. ubuntu_2404 provisions a 4 vCPU / 32 GB VM with a 64 GB disk, so ubuntu-latest-4-core keeps its core count while ubuntu-latest gains memory and disk over the GitHub-hosted standard runner. The runner group is the single non-default label alongside self-hosted; the service spawns one ephemeral VM per queued job. The e2e jobs stand up k3d clusters, which the runner image is already set up for: it ships docker and raises fs.inotify.max_user_instances, the limit that otherwise wedges multi-node k3s clusters part-way through startup. No step in this repo needs root, so nothing had to change beyond the labels.
