This component replaces reCAPTCHA and hCaptcha with a self-contained behavioral analysis engine. When a user interacts with the widget, it captures up to 300 pointer telemetry samples recording position, velocity, angular direction, and acceleration then runs them through a Naive Bayes classifier trained on human vs. bot movement profiles. The result is a probability score. If it crosses the configurable threshold, the user passes silently. No image grids. No audio challenges. No third-party network requests.
