Scope & fairness
This is the Documented-Policy tier: it measures how clearly the cancellation policy is published (cited, dated facts), not the behavioural experience of cancelling (Verified-Flow audit pending). Every company is scored on the same five dimensions with the same published weights, scores cannot be bought or removed. It is opinion grounded in disclosed facts, and not legal advice.
