Page.getResourceTree must aggregate frame/resource tree data from all WebProcesses. The tree structure is known in UIProcess (WebFrameProxy hierarchy), but resource details (mimeType, content size, etc.) live in individual WebProcesses. Work items: - IPC from ProxyingPageAgent to each WebProcess to collect resource data - Aggregate fragments into complete tree in UIProcess - Handle race conditions if frames navigate during aggregation - Consider hybrid approach: UIProcess builds tree from WebFrameProxy, fills in resource details from WebProcess responses Radar cross-reference: rdar://157031522
