Even if you are not explicitly "in scope" as an authority, MSR drives what authorities request and how fast you need to respond. Article 4 tasks include verifying declarations/technical documentation are drawn up and ensuring technical documentation can be made available on request (Article 4(3)(a)), providing information in a language easily understood by the authority (Article 4(3)(b)), and cooperating on corrective action (Article 4(3)(d)).
Use this as a readiness bar: can you retrieve, package, and explain evidence within days - and can you execute corrective actions (withdrawal/recall, listing removals, shipment holds) when needed?
