Hardly “complete details”,
Hardly “complete details”, especially with the bulk of the text prefixed with “likely” and “potentially”.
One thing owners can do is keep your foot firmly on the brake while moving the gear selector between forward and reverse and not accelerate until the transmission stops making noise. Unlike old automatics that you used to be able to “rock the car” out of various situations when stuck, the CVT takes a couple seconds to motor internal components into position. This is entirely speculation (based on 50 years of working on cars and aircraft), but I’d guess this is where the bulk of the damage from this particular issue is occurring (since the chain is being clamped after the input shaft is already spinning).
