- Add track filtering by uploader (my tracks / all tracks) with UI tabs - Add WebSocket ping/pong keepalive (30s interval) to prevent disconnects - Add auto-reconnect on WebSocket close (3s delay) - Add request logging middleware with DATABASE_URL output on startup - Handle missing S3 files gracefully (return 404 instead of 500) - Add debug logging for audio ended event 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
