fix: reconnect trending feed after app resume#235
Merged
Conversation
The trending feed used a single ephemeral relay that was evicted during reconnect. The new ephemeral connection only started after persistent relays finished connecting, causing the feed to appear stuck or show "no events found" after resume. - Pre-connect the trending relay in parallel with persistent relays via onPreReconnect callback in RelayLifecycleManager - Add RelayPool.preConnectEphemeral() to start WebSocket connection without sending a message - Add retry logic in subscribeTrendingFeed() to handle failed ephemeral connections (stale DNS, timeout after sleep) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
