Ysayle could control Shiva, Zenos via the Resonance could control Shinryu, but as for the rest, did they effectively temper themselves?
Which box does Ryne fall into?

Do I have this correct as per canon, or have I inferred sonething not explicitly stated in game?
Yotsuyu starts the Tsukuyomi fight in control. However, she loses it after the add phase, when the projection of Gosetsu protects her. It breaks her focus enough that the primal takes over ("From mortal husk, I rise anew!").

Thordan's summon wasn't intended to be channeling another entity; he was literally summoning himself as a god-king. It's kinda hard to say if he tempered himself to himself, and it's probably academic anyway.

Ryne has the Blessing of Light from Minfilia, so she's protected from tempering. She just wasn't mentally strong enough to control Shiva. Her perception being colored by the WoL's stories of Ysayle and Hraesvelgr probably didn't help.
