what is geetest?
a captcha-widget challenge; used by geetest; mints the geetest validate payload (challenge + validate + seccode) token; escalation: slider puzzle (default) → icon-order / point-and-click variants on a suspicious session → block on repeated failure. slider: drag a puzzle piece into the gap; the drag kinematics + timing are the behavioral read, scored server-side.
