- TCP: wider drain budgets, TCP_NODELAY, no flush, PSRAM buffers, queue announces until hub ID - GUI: object pool Messages/Contacts screens, partial MessageView status, targeted tab refresh - LVGL throttled to 5fps when dimmed, non-blocking RSSI monitor, bounded I2S writes - LXMF batch drain, BLE frame mutex, LoRa interrupt-driven RX, name cache cap 300 - Developer mode in settings: custom radio params (freq/txp/SF/BW/CR/preamble) behind warning
