Be interesting if there was a sanity check functionality where you can define the Rules for Sanity. I think they are hard coded now.
About the only places I’m aware of Sanity Checks upon commit is warn on unknown Gender and the Child to Parent relationship. (There are validator for Date & GPS CSV entry, but they are ultimately indifferent to commiting an unvalidatable value.)
I’d like a Sanity check for ‘unknown’ roles on Events. Because they are NEVER usable. added to the 5.2 Verify tool
