Do those OHKO moves break through High Affection?

Say a ground-type Pokemon uses Fissure against a, say, Sylveon. On normal circumstances, if the Sylveon DOESN’T have high affection (which it should because it needed high affection to evolve in the first place), then it would faint. But if it DOES have high affection, would those OHKO moves kill it?

If it has Sturdy, it is unaffected by OHKO moves.

Generations III and IVSturdy makes the Pokémon unaffected by one-hit knockout moves.

Generation V onwardIn addition to Sturdy’s previous effect, Sturdy now works like a Focus Sash, causing the Pokémon to have 1 HP remaining if another Pokémon’s attack or confusion damage would have brought it from full health to 0 HP.

Focus Sash also prevents OHKO moves.

If the holder has full HP and is hit by an attack that would otherwise cause fainting (including a one-hit knockout move), it survives with 1 HP.

As forAffection,it is currently unknown whether or not Affection can stop an OHKO move. Affection can sometimes guarantee an effect like Focus Sash, but for OHKO movesspecificallyI can’t find any sources that indicate if that is the case. If you guys know the answer to this please tell me.

And, for clarificstion, the only OHKO moves at the time of writing this are:

No! It won’t kill the Pokémon with any one of the above conditions exceptHigh affection. Because High affection won’t work always.It may or may not happen. So we can’t surely say that High affection will help to survive a KO move. So don’t trust affection.
