I've manually tested tapping the hardlock button on the lock screen, and then entering my password to unlock the device. Every time (5/5), EasyUnlock.AuthEvent.Unlock does not record "Password entry: User hardlock", but some other event, usually "Password entry: Phone authenticated". 

This logic being broken means that we don't have a good sense of whether or not users are tapping the hardlock icon regularly -- something we'd like to have a signal of in order to determine if the hardlock icon is confusing to users.
