+### Signals the car does not provide

+Checked 2026-10-17 against what actually reached InfluxDB (`schema.measurementFieldKeys`). The car
+sends soc, est_battery_range, odometer, power, voltage, current, speed, hvac_setpoint, the four
+tyre pressures, GPS (lat, lon, elevation, heading) and the is_* flags. It does **not** send:
+
+- **Battery temperature:** read from `EV_BATTERY_AVERAGE_TEMPERATURE`, an Android 14 property; the
+  head unit runs Android 9, and the SAIC services offer none.
+- **Cabin temperature:** `HVAC_TEMPERATURE_CURRENT` is not published; only the setpoint is.
+- **Outside temperature:** not published by the vehicle (upstream noted the same). Upstream used
+  the head unit's weather service as a stand-in (`HeadUnitWeather`, removed in `ea8032a`);
+  restoring it was considered and declined.
+- **Pack energy (`soe`) and capacity:** not published. The Live dashboard computes energy in pack
+  as SOC × usable capacity, from the hidden dashboard constant `usableKwh` (50.8 kWh for the
+  51 kWh battery) in `k8s/grafana/dashboards/live.json`.
