Key legal question
Whether the appellant had a rent-entitling disability degree, especially from February 2008 onward under the mixed method.
Extracted holding
No rent-entitling disability degree was established; the household limitation was not shown to justify a pension.
Extracted reasoning
The court upheld the binding medical findings: no relevant somatic limitation for light to medium work, no additional psychically caused reduction in earning capacity, and the household report was sufficiently reliable without extra medical input.
