lib/services holds the host-tested logic: - Settings: typed, validated, persisted, SettingChanged events, transmit gated on a confirmed Region - BatteryEstimator: LiPo curve, median smoothing against TX sags - ClockModel: source priority GNSS > NTP > mesh, relative ages, Europe/Brussels local time via POSIX TZ - StorageMonitor: warning once per boot at 80%, Logs stop at 90%, Captures stop with < 2 MiB left - PowerPolicy / PowerButton: dim/off timeouts, wake key swallowed only when the screen was off, G0 long press src/services wires them to the hardware (NVS, battery ADC, SD on the shared SPI bus with the LoRa CS held high, backlight, deep sleep), and main.cpp is a temporary diagnostics screen for the hardware checks.
