From fbc8d4d43a975426a01983e309762d7454520a82 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Tue, 17 Feb 2026 16:35:36 +0000 Subject: [PATCH 1/4] feat: Implement global MediaCache to deduplicate media across rooms - Move MediaCache to a global thread-local storage. - Update MediaCacheEntry to support multiple subscribers for pending requests. - Remove per-room MediaCache from TimelineUiState. - Update RoomScreen, LinkPreview, and RoomImageViewer to use the global cache. - Reduce memory usage and network requests for shared media.
