Struct ScreenDescription 

pub struct ScreenDescription {
    pub screenshot: Option<String>,
    pub elements: Vec<ElementSummary>,
    pub front_app: Option<String>,
    pub summary: String,
    pub captured_at: f64,
}

Aggregate screen description. elements is a DFS-collected ordered list of the visible+enabled ElementSummary entries a reader could name (anonymous layout containers are skipped); screenshot is an optional base64 PNG.

frontApp and capturedAt are filled at capture. Only summary is caller-populated. This comment used to call all three of them that, which is how two fields stayed unconditionally empty while a CLI help string promised a title and a status bar.

Fields

screenshot: Option<String>

Optional base64-encoded PNG screenshot of the screen.

elements: Vec<ElementSummary>

Nameable visible+enabled elements in DFS pre-order.

front_app: Option<String>

Bundle id of the app this description was taken from, read from the a11y tree root’s identifier.

Deliberately not called “frontmost”: the runner reports the app it resolved for the request, which is what a caller can act on. None when the root carried no identifier — distinct from an empty string, which would claim knowledge of an empty answer.

summary: String

Free-form one-line summary. The caller writes this; nothing in smix produces it.

captured_at: f64

Wall-clock capture timestamp (Unix epoch milliseconds).
