Kernrechtsfrage
Whether the appellant is entitled to an invalidity pension.
Extrahierter Entscheid
No pension entitlement was shown because no relevant incapacity to work before the expert assessment could be established with sufficient probability, and from the assessment date onward the appellant was deemed fully capable of adapted work.
Extrahierte Begründung
The cantonal court could rely on the comprehensive expert report; for the earlier period the medical file did not prove a relevant incapacity. Where proof remains unavailable after reasonable investigation, the party relying on the unproven facts bears the risk of evidentiary uncertainty.
