Disaster Index: 5.1 Entry: Succession Conditions Cause: The question of who follows Steve Clarke arriving before the question of what Clarke's tenure has actually built. Category: Administrative / Structural Evidence: Clarke's record includes two Euros qualifications and Scotland's first World Cup appearance in 28 years. The infrastructure that produced those results — tactical stability, squad continuity, expectation management — is not yet confirmed as transferable. The successor inherits a set of conditions they did not create. Historical precedent: Scotland has a documented pattern of appointing a successor to a successful manager and discovering that what the previous incumbent did was harder than it looked. Berti Vogts followed Craig Brown. The gap between inherited platform and delivered result was instructive. Affected parties: Scottish Football Association, incoming head coach, squad members whose international futures are tied to managerial continuity. Immediate outlook: No appointment has been made. The Index records the structural exposure, not the vacancy. The difficulty of the task is the entry. Filed: 30 June 2026 / Post-World Cup transition window
