Engine failure during a derated takeoff

[de facto]

My question was simple: with derated thrust option, are the CLB and MCT=CON N1 limits also reduced to be equal or below max N1(derated)?

Basic indeed.NO
If you use derate thrust V2,lest say (22k) and then bump it to CLB,then your thrust has gone up to 26K,so your VMCA increased,so your selected V2 may be below your new vmc a.
