You say that high speed protection is available in alt law.
What I read from (dated) material is that high speed stability is available. Pilot can overcome that, according to my dated sources. Overspeed prot, as I understand it, is only available in Normal Law. Protection as in "won't let the pilot go that far out of the box" by making control inputs to counter a tendency/trend to get out of the box.
What am I misunderstanding about the difference between overspeed protection and high speed stability?
