pub async fn back(
__arg0: State<Arc<AppState>>,
headers: HeaderMap,
__arg2: Json<HistoryReq>,
) -> (StatusCode, Json<ApiResponse<AckData>>)Expand description
POST /agentmux/browser/back — walk the pane’s history one step back.
Routed through CDP (Page.goBack) rather than
BrowserPaneManager::go_back to keep the resolver cache honest: the
target URL changes after the hop, so we invalidate the cache entry.
Returns ack-ok even when there’s no prior history — CDP is a no-op
in that case, and agents should query browser-pane-nav-state events
(or eval("location.href")) to confirm what happened.
