If the validation rules don't specify (either explicitly or implicitly) what the "length" in the rule corresponds to (if it concerns a natural-language field, it's probably grapheme clusters), then either you should fix the rule, or you care only about checking the box of "I checked the validation rules", in which case it's a people problem and not a technology problem.
I agree about Palantir but that’s a big deflection. And don’t patronise me. Paying your bills and paying enough attention to technical details to write good programs are in no way mutually exclusive.
