    Type Alias VisitorType

    VisitorType: "crawler" | "automation" | "unknown"

    Conservative visitor classifications detected from supported browser-side signals.

    • "crawler": a known crawler or automated-fetcher user-agent token matched.
    • "automation": an explicit automation user-agent token matched or navigator.webdriver is true.
    • "unknown": no supported crawler or automation signal was detected.

    "unknown" does not mean that the visitor is verified as human.

    This heuristic result is not suitable for authentication, authorization, fraud prevention, access control, or other security decisions.
