I'm not gonna go around unproving things which haven't been proven in the first place. You have failed to provide reference where it is explicitly noted that two are required, it is only said that a QRH is required onboard the aircraft. When you provide the appropriate reference for two being required then my argument of "as specified in the type certification of the aircraft" will still hold true. The fact of the matter is for all your detailed examples from the Airbus AFM, AOM or whatever manual you provide there has not been an explicit statement of two being required and in each case the QRH is referred to in the singular.
Now I'm gonna go beat my head against a wall because that might actually be more productive than arguing with CMLs.
