I don’t think the pieces of advice contradict each other. If exceptions are handled at the lowest scope possible, and exceptions are most useful when the rise above many scopes, then exceptions are most useful when the scope that encounters the error is very deep compared to the scope that can handle the error. This agrees with my intuition, that error codes are most fragile when they must be checked and re-raised across many scopes.
