No, I said the buffet comes from the wing root, but the
actual stall is when the tail stalls and looses lift (down
force) and then the nose pitches down because the still
flying wing CP is behind the CG.


That applies to canards. Tuft-testing of conventional layouts proves
that the pitch-down comes from the wing's airflow breaking up, and when
that happens the CP moves well aft of the CG and pitches the nose down.
Stalling stabilizers/elevators are dangerous and are not
designed into the conventional airplane. The early Cardinal had that
problem, and would drop the nosewheel hard on the runway during the
flare, sometimes breaking it. Cessna had to put slots in the stabilator
to keep it from stalling. Ice on the stab can also cause stabilizer
stall and control reversal (pull back, nose goes down). Not desireable
at all.
The aircraft service manual will have control surface travels,
as do the Type Certificate Data Sheets. Those travels are intended, in
part, to prevent stalling and control reversal.
