How to remove fixture box for fan bracket?

I'm trying to put up a ceiling fan in my bedroom while the wife is on a trip and this is the 3rd fan I've put up in this house.

I can't get the bracket for the old cheapo fixture out and can't figure out why without cutting back more drywall.

House is 70s era manufactured (the kind rolled in as 2-3 big pieces and dropped on a traditional foundation). Crawl space above would require crawling across fiberglass, but i suspect this bracket is original from the factory, and had to have been put up before drywall.

How is this thing attached and how to get it out? Or is it possible I've gotten lucky and it's fan rated? Tia

Even though this paper is about 18 mo old, I'm on the Mirror hype train now. WHAM/Realta team make the case for classic mirror end loss to actually be not that bad.

The results of the scaling laws are interesting too, Q is mostly dependent on NBI beam energy rather than mirror ratio which has a log dependence.

Tldr is they're going to recover energy from escaping particles, use the open fields as a natural exhaust port instead of divertors and balance that with fueling from the NBIs. Paraphrasing the authors, but ambitiously they think thermal net gain with Q_wp > 0.40 and electrical net gain Q_wp >0.85.
