Tech foul at the end of a quarter

Is this a correctable error? I mean, the book doesn't say anything about awarding a merited free throw at the wrong time.

This sounds like an error that can't be corrected, and therefore you'd have to go by what RulesGeek said. The technical foul penalties (free throws and possession) are over with, as they were part of the previous quarter. The next quarter will start normally, with an alternating possession throw-in.
