Kernrechtsfrage
Whether the claimant proved a contributory employment of at least 12 months within the reference period.
Extrahierter Entscheid
The claimant did not sufficiently prove that she had worked in contributory employment for the required period.
Extrahierte Begründung
The record lacked credible proof of wage payments, individual insurance account entries, and any indication of contribution payments; later-produced documents were not persuasive.
