Balance Assertions in Beancount - Beancount Documentation
https://beancount.github.io/docs/balance_assertions_in_beancount.html#beginning-vs.-end-of-day
> It might be worthwhile to provide an alternate version of date-based assertions that applies at the end of the day, e.g. “balance_end”. Beancount v1 used to have this (“check_end”) but it was removed in the v2 rewrite, as it wasn’t clear it would be really needed.
