Module: Menuconform::Rules::AgeRules

Defined in:
lib/menuconform/rules/age_rules.rb

Overview

AGE-001..002. AGE-001 is a name heuristic by necessity: menus don't label alcohol, which is exactly the problem. The exclusion list guards the known soda/dessert traps (root beer, ginger ale, rum raisin); keep both lists tight — a false 'unlabeled alcohol' error costs the report credibility.
