(deleted) It seems I might be missing something indeed...

Actually, I believe part of my original question still holds.
Looking at the definition of closed monoidal categories
/-- An object `X` is (right) closed if `(X ⊗ -)` is a left adjoint. -/
class Closed {C : Type u} [Category.{v} C] [MonoidalCategory.{v} C] (X : C) where
/-- a choice of a right adjoint for `tensorLeft X` -/
rightAdj : C ⥤ C
/-- `tensorLeft X` is a left adjoint -/
adj : tensorLeft X ⊣ rightAdj
It's defined as adjunction , but it seems the convention is (so ). Is that "intended"?

when I was working on a proof of Lawvere's fixed-point theorem I noticed that the evaluation map seemed to have the arguments reversed from what was in the literature... I wonder if this is why

@Bhavik Mehta might know why it's designed this way
