Struct ClientSession 

pub struct ClientSession {
    pub client_id: String,
    pub runtime: Arc<Runtime>,
    pub channel: Arc<WsChannel>,
    pub host: Arc<HostState>,
    pub memgine: Arc<Mutex<MemgineEngine>>,
    pub browser: BrowserSessionSlot,
}

Per-client session.

Fields

client_id: String

runtime: Arc<Runtime>

channel: Arc<WsChannel>

host: Arc<HostState>

memgine: Arc<Mutex<MemgineEngine>>

Memgine handle. Wrapped in tokio::sync::Mutex so dispatcher handlers can hold the lock across .await points without risking poisoning. Migrated from std::sync::Mutex in the car-server-core extraction (U1) per the “one-wrapper rule”.

browser: BrowserSessionSlot

Lazy browser session — first browser.run call launches Chromium, subsequent calls reuse it so element IDs resolve across invocations within the same WebSocket connection.
