themeless 11: check yourself

Quick lil themeless today! Kinda leaned into the “The Whole Point Of Indie Puzzles Is I Can Write Whatever Clues I Want” situation so I hope you enjoy that, or learn something. There’s unchecked squares in this… not for any reason! Just kinda felt like ignoring crossword conventions / idk was feeling nihilistic or whatever.

Many thanks to Wouter for a super quick test solve!
