Keep enough evidence for a product, legal, quality, or support reviewer to reconstruct the decision without relying on memory. The records should connect the product fact pattern to the specific MSR question: Article 4 role, distance-sales targeting, documentation request, border suspension, corrective action, serious-risk assessment, ICSMS case, or Safety Gate alert.
The strongest file is short but traceable: product identifier, applicable legislation, EU economic operator, source citation, authority or marketplace trigger, evidence reviewed, decision, owner, submission or action date, and open follow-up.
