- admin screen: telemetry via upstream LPPDataHelpers (ported; fixed its 1-byte humidity size), every field, per-channel, signed current (helpers/ui/telemetry_text) - battery %: both UIs show ZephyrBoard::getBattPercent() (discharge curve / fuel gauge) instead of a linear 3.0-4.2 V estimate - app/PowerPolicy: low-battery auto-shutdown + v-contact alert + autoshutdown CLI on every companion (headless too); under 2000 mV counts as no battery; default 3200 mV, stored 3300 migrated once - one time_sync.c for both UIs; ui_push_radio_state() for all roles - repeater admin screen in its own file; handleInput split per mode - dead UI code removed; companion help fits one reply frame
