Can STS do this?

[Breakingbadxx]

Does STS hold data about gold on your account? E.g. what you spent gold on at a specific time.

My friend claims 1m gold disappeared from their stash this afternoon.

There have been multiple claims of this kind from time to time.

Is it possible to be given a list of all gold transactions on an account that occured in a day?

It may just be bad memory.

Does STS hold such data to confirm this?

If they don't, how can they be sure bugs causing people to lose gold don't occur?
