Kernrechtsfrage
Whether the relevant incapacity to work began during the period of coverage with the occupational pension foundation, including the one-month post-insurance period.
Extrahierter Entscheid
The court held that the claimant did not prove, with the required probability, that the disabling incapacity began while insured.
Extrahierte Begründung
The IV decision fixed onset at 1 May 2009 and was binding absent obvious unsoundness. Earlier symptoms and later retrospective medical opinions did not establish an actual, work-relevant incapacity during coverage; employment records showed no health-related absence or reduction, and the alleged performance decline was not shown to be health-related in real time.
