The whole made for tv script came apart because two SEALS were at Benghazi. No one had planned for that. The SEALS became the ambassador's security and rewrote the script thus saving America.
I do not believe Stevens was part of the plan. A good plan works when few people know what is going on. Also more realistic in negotiations that he doesn't know of the plan. When questioned afterward he will tell the truth according to what he knows and block any further digging into exactly what happened. He was no in the plan as a designer of said plan.

I agree —i think it’s VERY unlikely Stevens knew of the plan.

It just adds more risk to an already risky operation.
