qMin(32, m_maxIntensity) gives 0 when firmware returns 0 for MaxIntensity (aberrant value). maxIntensity()==0 then causes every setMaxChargingCurrent call to be clamped to 0, falling into the <6 A path which pauses charging silently — the user sees the action succeed but the charger stops. qBound(6, val, 32) is correct in all cases: - firmware reports 16 A (mono Trydan) → 16 (real installation limit kept) - firmware reports 0 (aberrant) → 6 (safe floor, does not claim 32 A) - firmware reports 65535 (aberrant) → 32 (IEC absolute ceiling) The real installation limit still comes from MaxIntensity read on the device; the bounds [6, 32] are only IEC guardrails, not hardcoded defaults.
