    "Logic allocations, converter efficiency and diode drop are design allowances to measure, not guaranteed component maxima.",
    "TPS1H100 external-limit accuracy requires its datasheet voltage/load/overload conditions. Do not apply the 9-20 V arithmetic as a guaranteed 5 V limit or fast transient cap.",
    "R13 measures the motor-feed branch; the VBUS_RAW-to-D2 logic branch bypasses it.",
    "The knob runtime uses motor_permitted with calibrated readings, but the shipped PROFILE=None keeps motor drive disabled. No commissioned motor settings exist.",
    "No motor phase-current rating is assigned until the MCT profile, shunt/gain calibration, waveforms and thermal limits are verified.",
    "5 V motor operation remains unqualified; cable loss, startup, ADC error and 4.5 V driver headroom require physical testing."
