OptionalmetadataNavigation metadata, the native counterpart of the browser's history.state.
OptionaloriginWhere the intent came from, for logging and for handlers that care.
The URL to resolve. Relative paths are resolved against the configured base URL.
A navigation intent: the one cause this adapter captures.
Everything a native application can ask of the domain arrives as an intent to show a URL: the cold start, a deep link, a push-notification tap, an in-app navigation. They differ in where they come from, not in what they mean, so the adapter normalizes all of them into this shape before the kernel sees anything.
