Kurogiri's Grand rank

The closest I could find were these posts on Beast Lair.

From what I can get, what is now “Grand” was “Master” once upon a time. In KnK volume 6 maybe? That one was not translated, and the translation there is by cokesato is infamously bad.

I'm more confused as to where is it said that Ayaka is Frame.

Here is the portion as translated by cokesato:

My mastery of the arcana of the Runes at twenty years of age is often considered early, but there have been those who reached it earlier. One of those individuals, a man who studied in the Collegium of the African Atlas Mountains, I have not personally met, though all Collegium know his names and titles. The Master of Babel, Godword Mayday. The only weaver of an Art so potent and ancient, it borders on mythic sorcery.
