}Not scored: fewer than three checks apply, usually because no remote answered a credential-free probe or the server is a local package.

A server's first observation is its baseline; later probes record what changes.
Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.
