Yes, intervals should always be closed-open, everywhere.
MB> 2. The --invert option does nothing for the `budget` report. Correct?
I wouldn't be surprised at all if that were the case.

I would, yes.

That sounds right.

I think so?

I'm glad it's useful, but definitely, custom code can always go further.

Absolutely! I'd be honored to accept your PR.
