Yeah, I'm expecting to not be pretty. After all, it's had years to get
like this, and undoing it in an afternoon won't be possible.

But at the very minimum we need to stop it from getting any worse. We
have to at least try.

There doesn't appear to be any toenailing on the joists themselves,
just that plywood gusset. And the subfloor is glued (can see the drips)
and screwed (can see screws hanging down where they missed the joist
from above).

I'm expecting some possible mess upstairs with stuff popping up or
maybe cracking, but since we need to recarpet and repaint the whole
house interior this is a good time to do it.

No 400 lb TVs, but we do have a bunch of books.
