FIA Art.253.8 states that only bonding is permitted 'For non steel bodyshells/chassis, any weld between the cage and the bodyshell/chassis is prohibited, only the bonding of the reinforcement plate on the bodyshell/chassis is permitted.'

Which regulation mandates a bolted ROPS?

I don't know where or if bolting is mandated, but as far as I am aware, bolting is permitted as a form of belt and braces, no pun intended, as well as welding or bonding. Also permitted is the fitting of reinforcing plates beneath the body and/or the other side of the cockpit.
