This paper investigates the challenge of maintaining certification validity throughout the operational lifecycle of autonomous systems. Traditional certification approaches typically assume that certification is performed prior to deployment and remains valid throughout operation. However, autonomous systems increasingly operate in dynamic environments characterized by adaptation, learning, software updates, configuration changes, operational drift, and evolving system capabilities. The paper argues that these developments create a Certification Continuity Challenge: certification may remain formally valid while the operational conditions under which certification was originally granted continue to evolve. The study examines certification as a dynamic rather than static property and proposes Certification Continuity as an emerging research area concerned with preserving certification validity throughout operational change. The paper further explores the relationships between certification, assurance, governability, runtime monitoring, lifecycle management, and autonomous ecosystem governance. It argues that future autonomous ecosystems may require approaches capable of supporting continuous confidence in certification validity rather than relying exclusively on point-in-time certification decisions. The paper is intentionally conceptual and focuses on the scientific, regulatory, operational, and institutional implications of Certification Continuity without proposing implementation-specific architectures, protocols, or technical enforcement mechanisms.
