Probably useful if you revisit the old Principles of Flight notes .. especially the CL against alpha curve. Maximum CL corresponds to stall. Artificial devices, such as stick pushers/shakers are used if the stall characteristics have some nasty aspects from a certification aspect and need some help to get a tick in the box.
While I know little about the Caravelle (other than that it was a lovely looking aeroplane from the sidelines), the description you give sounds not much different in the end play to a stick pusher ?
