Package-level declarations

The nearest enclosing PortholeScreen name, so leaf nodes know where they live.

Semantics key carrying the porthole's node id.

Like collectAsState, but tells the porthole what the resulting State is called.

Reports a back stack the app owns, such as Navigation 3's.

Counts recompositions of the composable that applies it, and stamps the node id into semantics so the two trees line up.

Stable identity for a call site.

Wrap your app's root composable once. Gives the semantics collector a View to walk and establishes the timeline's root scope.

Marks a screen. Recompositions of this scope are counted and attributed, and every portholeNode underneath inherits the name.

remember { mutableStateOf(...) } with a name attached.
