RealHW exposes GitLab-compatible SaaS runner tags for convenience. If your job already uses GitLab hosted runner tags, start there.

## AMD64

- `saas-linux-small-amd64`
- `saas-linux-medium-amd64`
- `saas-linux-large-amd64`
- `saas-linux-xlarge-amd64`
- `saas-linux-2xlarge-amd64`

## ARM64

- `saas-linux-small-arm64`
- `saas-linux-medium-arm64`
- `saas-linux-large-arm64`

## Compatibility behavior

Larger hosts can advertise smaller compatible tags. For example, a host that can run `saas-linux-xlarge-amd64` can also advertise `saas-linux-small-amd64`, `saas-linux-medium-amd64`, and `saas-linux-large-amd64`.

Use the smallest tag that fits the job. Add RealHW hardware markers only when the job needs specialized hardware.
