Because, beatification requires proof of a miracle through the candidate’s intercession

and since the candidate cannot hear prayers in purgatory, the miracle itself is 'proof' that the candidate has departed purgatory and is now in heaven. Is that correct?

"...and since the candidate cannot hear prayers in purgatory, the miracle itself is 'proof' that the candidate has departed purgatory and is now in heaven. Is that correct?"

It's more accurate, I think, to say it's proof that God wants this servant of His to be honored, since it's God who actually wills and does the healing or whatever the miracle was.
