Function ruleset_satisfies 

pub fn ruleset_satisfies(
    ruleset: &Value,
    default_branch: Option<&str>,
    actions_id: Option<u64>,
    spec: &ProtectionSpec,
) -> Result<bool>

Whether ruleset — GitHub’s JSON for one repository ruleset, as GET /repos/{owner}/{repo}/rulesets/{id} returns it — already enforces spec on a repository whose default branch is default_branch, with the required check pinned to actions_id. The same test the adapter runs before it rewrites its managed ruleset, so a client that converges on it leaves a ruleset alone exactly when the bridge would.
