One honest picture of your month, whoever opens it.
The monthly check-in now builds one household snapshot for the month, the same numbers no matter which of you opens it. It leads with what you actually built, then reconciles the rest in the open: your saving, plus accounts you newly tracked, plus what the currency moved, adds up to the total you see. And a change to a planning assumption, like your expected return, now shows as a re-projection instead of a month's gain.
