Map answers to controls, not questions

Two buyers will phrase 'do you encrypt data at rest' a hundred different ways. Store your answers indexed by SOC 2 / ISO 27001 / NIST 800-53 control, not by the question text. The matching engine handles the rest.

Always cite the artifact

Every yes/no answer should reference a supporting artifact: policy doc, control test result, pentest summary, SOC 2 Type II report excerpt. Bare 'Yes' answers prolong the review.
