B.2.2:5.2 - Cloud Platform

Independent services become a platform only if the current claim concerns a result system: a shared control plane, system-level SLO, deployment and rollback coordination, platform-level evidence, and external commitments.

If the only change is a better dashboard or one more service, use architecture-description, publication, measurement, or component patterns. Use B.2.2 only when B.2 identifies the operating platform itself as the exact candidate new whole and that candidate passes A.1 plus the direct U.System criterion.
